Description

The present invention relates to a system that assists vehicle drivers by providing information on various traffic monitoring activities, such as traffic enforcement and checkpoints.

Conventionally, systems to assist vehicle driving include on-board devices such as radar detectors that sound an alarm when they receive speed enforcement radar waves, alerting the driver. Some such on-board devices have a GPS function that determines the vehicle's current location and a database of GPS content, such as the installation points of speed enforcement systems, and can detect approaching specific GPS content and alert the driver (see, for example, Patent Document 1). By notifying drivers of approaching traffic monitoring locations, such on-board devices can prevent them from unknowingly driving too fast.

The GPS content that an in-vehicle device configured as described above will notify of is approaching includes permanent points such as speed enforcement system installation points and police stations, as well as temporary points where traffic monitoring activities such as speed enforcement by mobile speed cameras and drunk driving checkpoints are frequently carried out. By notifying of the approach of various GPS content, the in-vehicle device aims to raise driver awareness of safe driving.

In particular, vehicle speed measurement devices used for speed enforcement are generally installed at dangerous points where excessive speeding is likely to be induced. Alerting drivers to approaching such points is highly effective in raising drivers' awareness of safe driving and preventing danger before it occurs. In-vehicle devices such as radar detectors are extremely useful for motivating drivers to drive safely, contributing to ensuring traffic safety and assisting drivers.

Some radar detectors equipped with a database of GPS content are equipped with a display that can show a map of the area around the vehicle. Such in-vehicle devices can perform a variety of alert functions, such as plotting the location of GPS content on a map or displaying an animated warning overlaid on the map.

However, the above-mentioned conventional in-vehicle devices have the following problem: User preferences vary, and while there are users who want very detailed information, there are also quite a few users who, because too much information can be difficult to understand, want only important information presented in an intuitive and easy-to-understand manner. Therefore, it is necessary to respond in detail to various user needs.

Japanese Patent Application Laid-Open No. 2007-248180

The present invention was made in consideration of the above-mentioned problems with the conventional technology, and aims to provide a vehicle system that can communicate information in an easy-to-understand manner to a variety of users.

A first aspect of the present invention is a vehicle system for controlling the display of monitoring information related to traffic monitoring activities on a screen, comprising:
A map area for drawing a map to display target icons representing implementation points of traffic monitoring activities and a panel area for notifying the monitoring information can be displayed on the screen,
The vehicle system is capable of setting the number of map areas to be displayed and the number of panel areas to be displayed, including zero, when a map is displayed on a screen.

A second aspect of the present invention is a program for causing a computer to implement the functions of the vehicle system of the first aspect.

In the vehicle system according to the present invention, the number of map areas and panel areas to be displayed can be set according to preference. In this system, by appropriately setting the number of map areas and panel areas to be displayed, the frequency of information notification and the level of detail can be adjusted.
In this way, the vehicle system according to the present invention is a system that can precisely meet various user needs.

The map displayed by the vehicle system of a preferred embodiment of the present invention may be a map of the area around the vehicle, or a map of the area around the location where traffic monitoring activities are being carried out. It may also be possible to display two types of maps with different scales of the area around the vehicle. It may also be possible to display two types of maps with different scales of the area around the location where traffic monitoring activities are being carried out.

In a preferred embodiment of the vehicle system of the present invention, a scope area can be displayed on the screen, which represents an equidistant range based on the current position of the vehicle and in which mini icons representing the locations where the traffic monitoring activities are carried out are displayed,
Link information can be displayed that indicates the correspondence between the mini-icon displayed in the scope area and the panel area that displays the monitoring information related to the mini-icon.
The display of the link information makes it easier to understand the correspondence between the mini-icons displayed in the scope area and the panel area. Even in a situation where multiple mini-icons are displayed, it becomes easier to understand the location of the traffic monitoring activity related to the monitoring information displayed in the panel area. The link information can be various information such as a text display showing the relationship, an arrow display showing the relationship, or a specific display of the same color. Any information can be used as long as it can show the relationship between the mini-icons and the panel area.

In a vehicle system according to a preferred aspect of the present invention, the link information is a line segment connecting the panel area and the mini icon.
By connecting the mini icon and the panel area with a line, the correspondence between the two can be understood at a glance, reducing the burden on the driver while driving.

In a vehicle system according to a preferred embodiment of the present invention, the panel area and the scope area are displayed so as not to overlap each other.
By avoiding overlap between the two, it is possible to prevent situations in which the mini icon is hidden by the panel area. It is also possible to display the scope area and panel area in predetermined, independent positions. By setting the display position of each area to a fixed position, it is possible to increase the user's sense of security and improve the ease of viewing the screen. When driving, there is no need to search for the display position of information, which improves safety.

In a preferred embodiment of the present invention, the vehicle system is capable of outputting monitoring information of traffic monitoring activities as audio,
The display mode of the link information relating to the panel area which notifies the monitoring information which is being output as audio differs from the display mode of the link information relating to the panel area which notifies the monitoring information which is not being output as audio.
In this case, the correspondence between the monitoring information to be output by voice and the link information can be clarified. The link information makes it easy to understand the correspondence between the monitoring information to be output by voice and the panel area and mini icon. It becomes relatively easy to understand the location and content of the monitoring information output by voice without having to look closely at the screen. If there is no need to look closely at the screen to understand the correspondence, usability is improved, and safety, especially while driving, can be improved.

In a preferred embodiment of the vehicle system of the present invention, a display color is defined according to the type of traffic monitoring activity, and the link information is controlled to be displayed in a display color according to the type of traffic monitoring activity related to the monitoring information reported by the panel area.
In this case, the type of traffic monitoring activity can be understood only by the display color of the link information, which reduces the burden on the driver while driving. Whether the monitoring information is important or not can be determined at a glance by the display color of the ring information.

In a preferred embodiment of the vehicle system of the present invention, an alarm level indicating the importance of the monitoring information is defined based on the type of traffic monitoring activity and the positional relationship between the current position of the vehicle and the location where the traffic monitoring activity is being carried out, and two display positions of the panel area with different priorities are set,
The panel area in the first display position, which has a higher priority, reports monitoring information at a higher alarm level than the monitoring information reported by the panel area in the second display position, and at a predetermined alarm level or higher.

In this case, the difference between the monitoring information presented in the first display position and the monitoring information presented in the second display position is clearly defined, and, for example, if you want to know monitoring information related to speed enforcement, you can simply pay attention to the panel area in the first display position. In this way, if the panel area to check is determined depending on the information you want, the burden on the user when obtaining information is reduced, thereby improving safety.

In a preferred embodiment of the present invention, the vehicle system is capable of outputting monitoring information of traffic monitoring activities as audio,
In the panel area of the first display position, monitoring information that meets the notification conditions is notified regardless of whether audio is being output or not,
In the panel area in the second display position, when audio is being output, notification of monitoring information of the traffic monitoring activity that is the subject of audio output is given priority over other monitoring information.

In this case, the monitoring information to be output by voice can be notified using the panel area in the second display position. Because the position of the panel area to be checked when voice output occurs is determined, there is less chance of missing the monitoring information output by voice. For example, even if the voice cannot be heard clearly, the content of the monitoring information output by voice can be confirmed by checking the content of the notification in the panel area in the second display position in accordance with the voice output. This reduces the risk of the driver becoming impatient and losing attention if they cannot hear the voice, thereby improving safety.

In a preferred embodiment of the vehicle system of the present invention, the display size of the panel area can be set to a first size, a second size smaller than the first size, or an automatic setting in which the display is switched between the first size and the second size depending on the situation.
If the display size of the panel area can be set according to the user's preference, it will be possible to respond to user needs in a more detailed manner. In particular, the above configuration is even more effective when the panel area is displayed superimposed on the map area. This is because user needs are diverse, with some users prefering a larger map display and others prefering a larger panel area.

In a preferred embodiment of the vehicle system of the present invention, a display field can be displayed on the screen to display the type of traffic monitoring activity, and the display mode of the target icon or mini icon related to the traffic monitoring activity displayed in the display field is different from the display mode related to other traffic monitoring activities.
In this case, the target icon or mini icon relating to the traffic monitoring activity displayed in the display field can be seen at a glance. The correspondence between the traffic monitoring activity displayed in the display field and the target icon, etc. can be quickly grasped, thereby reducing the burden on the user. There are various display modes, for example, a change in display color, a blinking display, an enlarged display, a display with movement such as enlargement and contraction, etc. Furthermore, the display mode of the display field may be set to the same display mode as the target icon, etc. In this case, it is even easier to grasp the correspondence.

In a preferred embodiment of the vehicle system of the present invention, two or more map areas having different scales can be displayed.
For example, by displaying two or more maps with different scales around the vehicle, it becomes easier to understand the positional relationship between the traffic monitoring activity site and the current location. This reduces the burden on the user and improves safety, especially while driving.

In a preferred embodiment of the vehicle system of the present invention, the panel area is displayed so as to be superimposed on a part of the map area.
In this case, the display area of the screen can be used effectively. It is preferable to display the panel area as a pop-up when the monitoring information is notified, and to erase it when the notification is not necessary. In this case, the display area for the map can be secured when the notification is not necessary, and the map can be made easier to see. On the other hand, if the panel area is made to appear when the monitoring information is notified, it becomes possible to attract the attention of the driver or the like according to the appearance action. The driver or the like who is driving only needs to pay attention to the appearance of the panel area, and can therefore concentrate on driving and ensuring traffic safety.

The microwave receiver 122 and the wireless receiver 123 are built into the case body 2 so as to be located on the rear side of the radar detector 1. This built-in position is suitable for receiving radio waves and the like coming from the front of the vehicle. The microwave receiver 122 has five levels of microwave field strength set, from Lv1 to Lv5, from lowest to highest.

The acceleration sensor 124 is a sensor that detects acceleration of the vehicle in the front-rear, left-right, and up-down directions.
The gyro sensor 125 is a sensor that detects angular velocity that occurs in response to running.
The geomagnetic sensor 126 is a sensor that measures the magnitude and direction of the geomagnetic field to detect the north direction.
The illuminance sensor 127 is a sensor that detects the external brightness.

The clock unit 129 is a clock that outputs calendar information. The calendar information includes data indicating the year, month, and date, and data indicating the current time. Once a day, when the current time is acquired from the GPS receiver 121, that time is used to calibrate the current time (including the date and time) of the clock unit 129.
The speaker 16 is mounted inside the case body 2 so as to be able to output sound and the like through a speaker hole (not shown) that opens on the bottom surface of the case body 2 .
The memory card reader 17 reads data recorded on the memory card 171 and transfers it to the control unit 10. The memory card reader 17 receives the memory card 171 inserted into the card slot 27.

The control unit 10 is configured by a microcomputer (not shown) including a CPU, a ROM, a RAM, a nonvolatile memory such as an EEPROM, an I/O, and the like.
The ROM stores software programs to be executed by the CPU.
The storage area of the nonvolatile memory such as an EEPROM is provided with a setting information storage area for storing setting information such as alarm settings.

The database 100 is configured as a non-volatile memory (e.g., EEPROM) either within the microcomputer of the control unit 10 or external to the microcomputer. At the time of product shipment, the database 100 contains map data, GPS targets including location information for warning targets, various facilities, and tourist spots, regulatory information such as speed limits, as well as various information for audio output.

The data stored in database 100 can be updated using memory card 171. When memory card 171 storing update data such as map data, GPS targets, and audio output information is inserted into memory card reader 17, the update data is read out under the control of control unit 10, and the data in database 100 can be updated. It is also possible to update database 100 by connecting a PC with update data stored on a hard disk or the like via USB.

A posting pin memory area is provided in the memory area of the microcomputer in the control unit 10 or in a non-volatile memory (e.g., EEPROM) external to the microcomputer, for storing information about the traffic monitoring activity to be posted. The posting pin memory area can store up to four pieces of posting pin information about the traffic monitoring activity to be posted. The data specifications of the posting pin information will be explained in detail later.

■ 3. Basic operation ■
The radar detector 1 realizes various functions by having the CPU execute software programs read from the ROM. The functions of this radar detector 1 include a current information display function, a GPS log function, an alarm function that issues various alarms, an OBD function, a setting function, and a registration function. The alarm functions include functions that are common to radar detectors, such as a GPS alarm function, an RD alarm function, and a wireless alarm function. Furthermore, the radar detector 1 of this example also has a posting function that generates posted information. Each of the means for realizing these functions is formed in the control unit 10.

The current information display function displays current information by displaying a preset standby screen on the touch panel 15. Current information includes various types of information such as map information around the vehicle, location information of surrounding GPS targets, time information, tide information, vehicle information, fuel efficiency information, eco-driving information, satellite information, and altitude information. The current information to be displayed can be selectively set by selecting the standby screen. Selective setting of the standby screen is achieved using the setting function described below.

The OBD function acquires vehicle information. This OBD function only functions when the radar detector 1 is connected to the vehicle via an OBD adapter cord that is connected to the vehicle's OBD connector. By connecting the radar detector 1 to the vehicle using the OBD adapter cord, various vehicle information can be acquired every 0.5 seconds. Vehicle information that can be acquired from the vehicle includes, for example, vehicle speed, engine RPM, engine load factor, ignition timing, intake manifold pressure, intake air flow rate (MAF), injection open time, engine coolant temperature (coolant temperature), temperature of air drawn into the engine (intake temperature), temperature outside the vehicle (outside air temperature), fuel flow rate, instantaneous fuel consumption, accelerator position (throttle position), turn signal information (operation information for left and right turn signals), brake position, and steering wheel rotation angle information.

The GPS log function is a function that stores the current position output from the GPS receiver 121 every second as a position history in the database 100. This position history is recorded in, for example, the NMEA format. The stored current position is associated with the time and speed (vehicle speed) at which the control unit 10 detected the current position.
The registration function is a function that allows the driver, who is the user, to register personal locations (my points) and areas (my areas), and is executed by a registration means realized in the control unit 10 as software.

The GPS warning function warns of approaching objects such as speed cameras (automatic speed enforcement devices). The GPS warning function repeatedly performs calculations at predetermined intervals (e.g., every second) to determine the distance between the location of the object to be warned and the current location. When this distance reaches a predetermined approach distance and an event known as approaching a warning point occurs, a GPS warning indicating this is issued.

The targets that may be alerted by the GPS alert function include speed cameras, enforcement areas, checkpoints, intersection monitoring points, no-parking monitoring areas, N systems, traffic monitoring systems, red light ignorance prevention systems, police stations, accident-prone areas, areas prone to vehicle theft, sharp curves, junctions and merging points, ETC lanes, etc. Database 100 stores information about the type of these targets, location information (latitude and longitude) indicating their location (specific position), schematic diagrams (animations) or photo data to be displayed on touch panel 15, and audio data in a correlated state as GPS targets (POI data). Alert targets may also include locations of drowsy driving accidents, radar, speed limit change points, etc.

Note that GPS targets other than those alerted by the GPS warning function include service areas (expressways), parking areas (expressways), highway oases (expressways), smart interchanges (expressways), gas stations inside PAs/SAs (expressways), tunnels (expressways), highway radio reception areas (expressways), prefectural border announcements, roadside stations, and viewpoint parking areas.

In the radar detector 1 of this example, GPS targets are managed in four levels of classification, as shown in Figure 4, in descending order of alarm level indicating urgency: "Red" → "Yellow" → "Blue" → "Green." Each color corresponding to the GPS target classification is set as the display color of the icon, as well as the scope color on the classic scope screen (reference numeral 32 in Figure 15, described below), the display color of the ring action by the ring display (reference numeral 34 in the same figure, described below), and the light color of the multi-color LED 137.

The RD alarm function alerts you to the incidence of radar waves (microwaves) emitted by a radar enforcement device. When an event occurs in which the microwave receiver 122 receives radar waves (hereinafter referred to as RD reception), an RD alarm is issued to indicate this.

The radio warning function issues warnings so as not to interfere with the operation of emergency vehicles, etc. When an event occurs in which radio waves emitted by an emergency vehicle, etc. are received (hereinafter referred to as radio reception), a radio warning is issued to alert the driver. Warnings can be issued for police radio, car location radio, digital radio, special small radio, police station radio, police telephone, police activity radio, towing radio, helicopter radio, fire helicopter radio, fire department radio, ambulance radio, highway radio, security radio, etc.

The posting function is a function for generating posted information such as traffic enforcement information. In this example, the radar detector 1 converts the generated posted information into a two-dimensional code image 15C (described below with reference to FIG. 163) and displays it on the touch panel 15. In this example, a QR code (registered trademark) is used as the two-dimensional code image. Various code images, such as one-dimensional barcodes, can be used as the code image. Instead of a code image, characters can be displayed and the characters can be recognized. Alternatively, wireless communication such as IRDA, IRDX, NFC, or Bluetooth (registered trademark) can be used. The operation for generating posted information is as described below.

The setting function is a function for making various settings related to the radar detector 1. Settings include standby settings related to the standby screen, mode settings, alarm settings related to alarm operation, screen/LED settings related to the touch panel 15 and light-emitting unit 23, audio settings, posting settings, reminder settings, system settings, custom settings, and OBD settings. The contents of each setting will be explained later.

Next, an overview of the operation of the radar detector 1 of this example will be described. In standby mode, when no events requiring an alarm, such as RD reception, radio reception, or approach to an alarm point, are occurring, the control unit 10 displays the standby screen on the touch panel 15. In the radar detector 1 of this example, the default standby screen is the map screen 31. When operation of the MEMORY button 222 is detected while the standby screen is displayed, the control unit 10 pops up four registration menu buttons 313 on the screen (center screen), as shown in Figure 5. The registration menu buttons 313 include a pin setting button for registering a posting pin 44 (see Figure 157), as described below, an IT map button for displaying a two-dimensional barcode containing the latitude and longitude of the vehicle's position when the MEMORY button 222 was pressed, a My Area button for registering a My Area, and a Cancel button for registering a My Cancel Area.

When operation of the MEMORY button 222 is detected when all four possible posting pins 44 have been registered, the control unit 10 displays a pop-up message saying "Full of pins" instead of the pin setting button, as shown in FIG. 6(a). When operation of the MEMORY button 222 is detected when the vehicle is not moving at all, the control unit 10 displays a pop-up message saying "Direction undetermined" instead of the pin setting button, as shown in FIG. 6(b). When GPS positioning is not in progress, the control unit 10 displays the text "Searching for GPS" at the top as shown in FIG. 6(c) when it detects operation of a menu button other than the ITY map button, and switches to a screen with the message "Searching for GPS" in the center as shown in FIG. 6(d) when it detects operation of the ITY map button.

When any of the following events occurs during standby: approaching an alert point, receiving a radio signal, or receiving a radio signal, the control unit 10 executes processing to execute the corresponding function: GPS alert function, radio signal alert function, or radio signal alert function. When two or more events occur simultaneously, the priority of each function is, from highest to lowest, the radio signal alert function, followed by the GPS alert function.

■ 4. Standby screen settings and specifications ■
In the radar detector 1 of this example, when there are no alarms or notifications, a standby screen that displays various information useful for driving is displayed on the touch panel 15. The standby screens available are (1) radarscope screen, (2) clock screen, (3) speed screen, (4) eco-driving screen, (5) acceleration screen, (6) tilt screen, (7) digital meter screen, (8) tide information screen, (9) preset A screen, (10) preset B screen, (11) preset C screen, (12) photo frame screen, (13) graph screen, (14) altitude screen, (15) satellite information screen, (16) fuel consumption plan screen, and (17) OBD data screen.

When the control unit 10 detects operation of the VIEW button 221, it switches to displaying the standby list screen 3A shown in Figure 7. This standby list screen 3A displays a list of the 17 types of screens listed above that can be set as standby screens to be displayed while waiting for an alarm event. This standby list screen has operation buttons that display the 17 types of screens (1) to (17) in reduced size, as well as an AUTO button 302 and an OFF button 303 arranged in two dimensions.

All of the operation buttons on the standby list screen 3A, including the AUTO button 302 and OFF button 303, are touch switches. However, the operation button corresponding to the (17) OBD data screen is only enabled when the device is connected to the vehicle via the OBD adapter cord so that it can communicate with the vehicle. When not connected, the control unit 10 shades the operation button corresponding to the (17) OBD data screen so that it cannot be selected. Note that instead of shading, the button may be hidden.

When the control unit 10 detects a touch operation on any of the operation buttons, it sets that screen as the standby screen. Furthermore, when the control unit 10 detects a touch operation on the AUTO button 302, it switches between pre-set screens out of 17 types of screens that can be set as standby screens every minute and displays them on the touch panel 15. The screen that is switched by operating the AUTO button 302 can be set appropriately from among the 17 screens by user operation. Note that the initial settings at the time of product shipment are set to all 17 types of screens (16 types of screens excluding the OBD data screen when the OBD adapter connector is not connected) as the screen that is switched by operating the AUTO button 302. When the control unit 10 detects a touch operation on the OFF button 303, the control unit 10 makes the touch panel 15 blank in standby mode, thereby setting a completely black screen as the standby screen.

(1) The radarscope screens available are the map screen 31 (see Figure 12), which mainly displays a map, and the classic scope screen 32 (see Figure 15), which mainly displays a radarscope. The radarscope screen in Figure 7 is a reduced version of the map screen 31. The screen specifications for the map screen 31 and the classic scope screen 32 will be explained in detail in "5. Radarscope Screen Specifications" after an overview of the 17 types of screens has been given.

In the initial settings at the time of product shipment, the map screen 31 of the radarscope screens (1) above is set as the standby screen. On the standby list screen 3A in the product shipment state, the map screen is displayed as a reduced version of the radarscope screen 32 (see Figure 7). Whether the map screen 31 or the classic scope screen 32 is set as the radarscope screen can be selected using the setting function described below.

(2) The clock screen is a screen that combines an analog clock-style display with a date and day of the week display.
(3) The speed screen is a screen that combines an analog meter that displays the vehicle speed and a compass that displays the direction.
(4) The eco-driving screen (FIG. 8) is a screen that has a radar chart display section on the left, an overall evaluation display section on the upper right, and a driving speed display section on the lower right. The radar chart display section displays points for sudden acceleration on the upper side, sudden deceleration on the right, idling on the lower side, and economical speed on the left. The overall evaluation display section displays the average value of each point displayed on the radar chart display section. The driving speed display section displays the current speed obtained from the GPS receiver 121.

(5) The acceleration screen has an acceleration image display section on the left and an acceleration numerical value display section on the right. The acceleration image display section displays the direction and strength of acceleration as an arrow direction and magnitude (vector).
(6) The tilt screen is a screen that has a tilt image display section on the left side that displays an image of the vehicle's tilt state, and a numerical display section on the right side.
(7) The digital meter screen is a screen that digitally displays heading, vehicle speed, etc. FIG. 9 is an example when the display item is set to heading, and FIG. 10 is an example when the display item is set to RPM. On these digital meter screens, numbers representing heading and vehicle speed are displayed in segments like a digital clock. A compass is located on the right side of these digital meter screens. This compass is formed by drawing an elliptical area viewed obliquely from the north-south-east-west plane and a magnetic needle rotating inside this elliptical area inside a ring-shaped outer periphery. The time is displayed numerically in the upper right corner of the screen, above the compass, and the date and day of the week are displayed numerically in the lower right corner of the screen, below the compass.
(8) The tide information screen is a screen that includes a tide level graph display section.
(9) to (11) Preset A to C screens are screens that allow the placement of up to three circular ring displays (information display areas) 34. Each ring display 34 displays a type of display item preset by user operation. To ensure as large a display area as possible, as shown in FIG. 11 , the ring display 34C is positioned higher than the ring displays 34L and 34R on either side, resulting in the three ring display sections 34 arranged in a mountain shape. Furthermore, the ring display sections 34 are positioned so that they partially overlap, thereby ensuring a large display area. The central ring display 34C is displayed in the foreground, and the ring displays 34L and 34R on either side are displayed behind. When the ring display section 34C is displayed, the outer peripheries of the ring displays 34L and 34R are partially hidden.

The display items that can be preset for each ring display 34 differ depending on whether the OBD is connected or not. When the OBD is not connected, the following display items can be preset: clock, vehicle speed, acceleration, incline, tide information, compass, eco-driving, and satellite information. When the OBD is connected, in addition to these display items, the following can be preset: instantaneous fuel economy, average fuel economy, general road average fuel economy, highway average fuel economy, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow, engine water temperature, intake air temperature, outside air temperature, engine load, intake manifold gauge, boost gauge, tachometer, battery voltage, throttle opening, etc.

As shown in Figure 11, on a preset screen where the ring display 34 is arranged in a mountain shape, the status icon 35 is displayed blinking in the gap at the top left of the screen. This figure shows an example where a no parking area icon 351 and a high-theft-prone area icon 352 are displayed. When not within an area, the status icon 35 is lit very dimly and cannot be recognized against the background. However, if the no parking area or high-theft-prone area setting is turned off by mode setting or manual setting, the status icon 35 is completely off without lighting up. The display specifications for the status icon 35 are the same for all standby screens except the radarscope screen. The display of the status icon 35 is omitted on the map screen 31 in Figure 12. On the classic scope screen 32 in Figure 15, the status icon 35 is displayed in the lower left (see Figure 84).

(12) The photo frame screen is a screen that displays image data set by user operation. Multiple image data can be set, and when multiple image data are set, each image data is displayed in a rotating sequence.
(13) The graph screen is a screen that includes a graph display section and a numerical display section. The graph display section displays the type of graph set by the user. The numerical display section displays the current value. The types of graphs that can be displayed are speed, altitude, and acceleration.
(14) The altitude screen is a screen that displays a graph of altitude changes.
(15) The satellite information screen is a screen that displays the positions of satellites currently receiving GPS signals on an illustration of a globe.
(16) The fuel consumption planning screen is a screen that includes a display section that displays OBD data in text and a meter display of fuel consumption.
(17) The OBD data screen is a screen that displays selected OBD data. The OBD data includes various data such as “speed,” “average speed,” and “maximum speed.”

■ 5. Radarscope screen specifications ■
The radarscope screens include a map screen 31 (FIG. 12) and a classic scope screen 32 (FIG. 15). In the radar detector 1 of this example, either the map screen 31 or the classic scope screen 32 can be selectively set as the radarscope screen by using the radarscope setting described below.

■ 5.1 Map screen specifications ■
As shown in Fig. 12, the map screen 31 displays a map of the area around the vehicle. Within the map screen 31, the vehicle's position is displayed by a triangular vehicle icon 311. At the top of the map screen 31, there are arranged a direction display section 312 that displays the north direction on the map, a vehicle speed display section 315 that displays the vehicle speed, and a time display section 314 that displays the time digitally. At the bottom of the map screen 31, there is arranged a strip-shaped caption display section 37. This caption display section 37 is composed of a first display section (display field) 371 on the left and a second display section 372 on the right. A target icon 316 that represents the location of a GPS target (such as a location where traffic monitoring activities are being carried out) is plotted on the map screen 31.

If there is no GPS target to focus on (focus target), the first display unit 371 displays the name of the current location as shown in Figure 13, and if there is a focus target, target information is displayed as shown in Figure 14. As shown in Figure 12, the second display unit 372 displays public enforcement information related to the current date and time. Here, the focus target is the target located in front of the vehicle and at the shortest distance. However, if audio output is generated, the target for which audio output is made will be set as the focus target even if it is not the shortest distance. Note that in the case of targets with a surveillance direction, such as speed cameras, the vehicle must be within an angular range of ±40 degrees of that direction in order to be set as the focus target. The target icon for this focus target is the focus target icon.

The first display unit 371 is designed to display the map while hiding it. On the other hand, the vehicle speed display unit 315, time display unit 314, and second display unit 372 are designed to display text that appears to float on the displayed map. This display specification allows the map to be displayed in as large an area as possible. For example, even when the second display unit 372 is displayed, encroachment on the map display area can be suppressed, ensuring a wide display area.

Depending on the settings, the map screen 31 displays an alarm panel 36 or a mini radarscope 38. The alarm panel 36 is a rectangular display area that pops up in response to an alarm sound (voice). The alarm panel 36 displays information about an alarm event that has occurred using photos and animations. Note that with the radar detector 1 of this example, it is also possible to select a setting that does not display the alarm panel 36 using the map detail settings described below. This type of specification is effective for meeting a wide range of user needs in detail.

The mini radarscope (scope area) 38 is a circular display area that appears when approaching a GPS target, etc. The mini radarscope 38 is a roughly circular window modeled after the radar screen of an airport control tower. In this mini radarscope 38, a triangular vehicle icon 381 is displayed in the center of the circular display area, and the target's position is displayed using a granular mini icon 383. The mini radarscope 38 allows for intuitive display of the positional relationship between the vehicle's position and the target's position, as well as the distance to the target. Furthermore, within the mini radarscope 38, the distance to the target is displayed numerically below the vehicle icon 381. The mini radarscope 38 fades in while expanding into a circular shape as the target appears, and fades out while shrinking into a circular shape as the target disappears. Among the mini icons 383 displayed on the mini radarscope 38, the GPS target displayed in the first display unit 371 flashes to indicate its correspondence with the GPS target displayed in the first display unit 371. The display on the first display unit 371 also alternates between a colored state corresponding to the type of GPS target and an uncolored black and white display state.

■ 5.2 Classic Scope Screen Specifications ■
As shown in FIGS. 15 and 16 , the classic scope screen 32 is a display simulating the radar screen of an airport control tower. The classic scope screen 32 displays a scope surface on which circular areas are drawn every 500 meters, based on the vehicle's position, so that the distances can be distinguished. Specifically, equidistant circles of 500 meters, 1000 meters, etc. are displayed with white lines 323, and each area 321 separated by these white lines 323 has a different brightness, etc. Furthermore, white lines are displayed to indicate the heading of zero degrees, ±25 degrees relative to the heading, ±80 degrees relative to the heading, and ±90 degrees to the left and right. The area between the white line 325D representing the heading of zero degrees and the white line 325B representing the heading of ±25 degrees corresponds to the vehicle's heading. The area sandwiched between the white lines 325C representing the ±80° direction and the white lines 325H representing the left and right directions is the area that will be the direction of travel when turning at an intersection.

On the classic scope screen 32, the vehicle position is indicated at the bottom of the screen by a triangular vehicle icon 322. There are three positions for the vehicle icon 322 on the left and right sides of the classic scope screen 32. In addition, there are two positions on the top and bottom sides of the screen. As will be explained in more detail below, on the classic scope screen 32, one of the vehicle icon 322 positions is selected depending on whether the scope sub-display 34 is displayed, the position and type of the focus target, etc. The classic scope screen 32 is provided with four scales ranging from 2000m far to 500m close, and the maximum distance of the displayed circular area differs for each scale.

On the classic scope screen 32, a scope sub-display 34 surrounded by a circular ring (outer periphery) 340 is displayed in the upper left corner depending on the settings and situation. This scope sub-display 34 has the same specifications as the ring display 34 in the preset screen (Figure 11). In the following explanation, the ring display 34 in the classic scope screen 32 will be specifically referred to as the scope sub-display 34. Unless the scope sub-display 34 is set to OFF (non-display), one of the following display items will be displayed according to the setting: clock, vehicle speed, eco-driving, acceleration, incline, tide information, satellite information, alarm panel, compass, air pressure, reminder days, reminder distance, instantaneous fuel economy, average fuel economy, average fuel economy on ordinary roads, average fuel economy on expressways, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow rate, engine water temperature, intake air temperature, outside air temperature, engine oil temperature, battery voltage, throttle opening, intake manifold gauge, boost gauge, tachometer, battery current, HV battery capacity, HV battery current, HV motor RPM, HV motor torque, and HV generator RPM.

The initial setting of the scope sub-display 34 is the warning panel 36 in FIG. 15. When the warning panel 36 is set, the control unit 10 pops up the scope sub-display 34 in conjunction with an alarm sound (voice). When an alarm sound has not been generated, the scope sub-display 34 is not displayed. On the other hand, for example, when vehicle speed is set as the scope sub-display 34 ( FIG. 16( a)), or when a compass is set as the scope sub-display 34 ( FIG. 16( b)), the scope sub-display 34 is always displayed on the classic scope screen 32.
In addition, in the scope sub-display 34 in which the alarm panel 36 is set, the ring action described below is executed using the ring 340 that forms the outer frame. Note that this ring action also applies to the ring display 34 in which the alarm panel 36 is set within the preset screen.

■ 6. Settings ■
In the radar detector 1 of this example, various settings can be configured using a settings list screen 1A, which is switched in response to touch operations on the standby screen, as shown in FIG. 17 . This settings list screen 1A has setting buttons corresponding to (1) standby settings, (2) mode settings, (3) alarm settings, (4) screen/LED settings, (5) audio settings, (6) posting settings, (7) reminder settings, (8) system settings, (9) custom settings, and (10) OBD settings. The contents and operations of each setting are explained below. However, (6) posting settings will be explained in detail in "10. Posting."

■ 6.1 Standby settings ■
The standby settings are settings for each screen that is a candidate for the standby screen. When the control unit 10 detects an operation of the standby setting button in the setting list screen 1A in Fig. 17, it switches to displaying the standby setting screen A as shown in Fig. 18. This standby setting screen A has setting buttons arranged corresponding to the radarscope setting, tide information setting, graph setting, auto item setting, preset screen setting (three types A to C), photo frame setting, digital meter setting, fuel consumption meter setting, and OBD data setting.

■ 6.1.1 Radarscope settings ■
When the control unit 10 detects operation of the radarscope setting button, it displays one of the radarscope selection screen AA1, the standby⇔radarscope switching screen AA2, and the GPS target search range setting screen AA3, as shown in Fig. 19. When the radarscope setting button is operated, the control unit 10 first displays the radarscope selection screen AA1, and switches the screen display sequentially in response to operation of the right arrow button (page forward button) or the left arrow button (page back button) in the lower right corner.

The standby⇔radarscope switching screen AA2 has setting buttons for alarm/1000m proximity switching, alarm/500m proximity switching, and fixed standby. For example, when alarm/1000m proximity switching is set, the control unit 10 switches to the radarscope screen when an alarm sound is generated or the focus target is within 1000m. On the other hand, when fixed standby is set, the control unit 10 does not switch to the radarscope screen. Note that the setting buttons on the standby⇔radarscope switching screen AA2 are only operable when a screen other than the radarscope screen is selected as the standby screen. When the radarscope screen is selected as the standby screen, the message "If the standby screen is radarscope, it will be fixed to radarscope" is displayed, and the setting buttons are disabled (made inoperable). Note that even when fixed to a standby screen other than the radarscope screen, various alarms can be issued if the alarm panel 36 is set in the ring display 34 within the preset screen.

The GPS target search range setting screen AA3 has setting buttons for optimal range and wide range. The optimal range is a setting that makes GPS targets appear according to the alarm distance and facing angle, narrowing down the targets on the radarscope screen to only those necessary, improving visibility. The wide range is a setting that makes red targets (red GPS targets in Figure 4) and yellow targets (yellow GPS targets) appear within the range that can be seen on the screen. Note that even when the wide range is set, the control unit 10 controls targets other than the red and yellow targets in the same way as when the optimal range is set.

When the control unit 10 detects operation of the map detail settings button on the radarscope selection screen AA1, it displays one of the following screens, as shown in Figure 20: the map display format setting screen (a), the map mode setting screen (b), the focus movement setting screen (c), the zoom display setting screen (d), or the icon display setting screen (e). As with the radarscope settings described above with reference to Figure 19, each screen can be switched by operating the right arrow button (page forward button) or the left arrow button (page back button) in the lower right corner.

The map display format setting screen (a) has setting buttons for north-up and heading-up. North-up is a display format in which north is at the top of the screen. Heading-up is a display format in which the direction of travel of the vehicle is at the top. Note that display format setting cannot be performed on wide-area maps when two maps are selected in the next map mode.

The map mode setting screen (b) has setting buttons corresponding to each map mode: No 1 Map Panel, Automatic 1 Map Panel, Small 1 Map Panel, Small 1 Map and 2 Panels, No 2 Map Panels, and Small 2 Map Panels. Here, "map" refers to the map area, and "panel" refers to the alarm panel area. "1 map" refers to one map area, and "2 maps" refers to two map areas (map areas). "2 panels" means that two alarm panel areas can be displayed. "Small panel" means that the maximum display size of the alarm panel is small. "Automatic panel" means that the alarm panel size will automatically switch to large when the distance to the GPS target is within 600 m. Map mode settings and the map screen under each mode are explained in detail in "7.1 Map Screen Settings and Operation."

The focus movement setting screen (c) has setting buttons corresponding to ON and OFF. ON is a setting where the screen moves so that the focus target is at the center while an alarm sound is being output. OFF is a setting where the screen does not move even when an alarm sound is output. Note that when two maps are selected in map mode, the focus movement setting is disabled on the wide-area map and is fixed to OFF. The default value for the focus movement setting is ON.

The zoom display setting screen (d) has setting buttons for ON and OFF. ON is a setting that automatically changes the scale so that the focus target can be displayed on the screen as much as possible. OFF is a setting that fixes the scale. Note that the zoom display setting is disabled on the wide-area map when two maps are selected in map mode. When set to ON, as shown in Figure 21, the scale of the map screen 31 is automatically changed according to the distance from the focus target under the control of the control unit 10. As shown in the same figure, when detailed view is displayed, place names and facility icons are displayed on the map screen 31 (a), and when the map scale becomes wider than a certain size, the place names and facility icons are erased (b).

The icon display settings screen (e) has setting buttons for convenience stores ON/OFF, fast food restaurants ON/OFF, family restaurants ON/OFF, gas stations ON/OFF, and other ON/OFF. By operating each setting button appropriately, you can turn facility icons on the map ON or OFF. By default, only "other" is set to ON. Multiple setting buttons can be selected. However, when a two-map map mode is selected using the map mode settings described below, the icon display setting is disabled on the wide-area map, and all settings are turned OFF.

When operation of the classic selection button on the radarscope selection screen AA1 (Figure 19) is detected, the control unit 10 switches to the display settings screen for the classic scope screen 32 (Figure 15), as shown in Figure 22. The classic scope screen 32 includes the following setting screens: a scope sub-display setting screen (a in the figure), a scope sub-backlight setting screen (b), a scope sub-backlight color setting screen (c), a scope sub-semi-transparent mode setting screen (d), a scope sub-additional information display setting screen (e), a public enforcement automatic pop-up setting screen (f), and an in-scope clock display setting screen (g). The specifications of the classic scope screen 32 are explained in detail in "7.2 Operation of the Classic Scope Screen."

The scope sub-display setting screen (a) is a screen for setting the display items of the scope sub-display 34 (see Figures 15 and 16) in the upper left corner of the classic scope screen 32. The display items of the scope sub-display 34 can be selected from the following: OFF, clock, vehicle speed, eco-driving, acceleration, incline, tidal information, satellite information, alarm panel, compass, atmospheric pressure, reminder days, reminder distance, instantaneous fuel economy, average fuel economy, general road average fuel economy, highway average fuel economy, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow, engine water temperature, intake air temperature, outside air temperature, engine oil temperature, battery voltage, throttle opening, intake manifold gauge, boost gauge, tachometer, battery current, HV battery capacity, HV battery current, HV motor RPM, HV motor torque, and HV generator RPM. When the scope sub-display 34 setting operation is performed, the control unit 10 displays a preview for a certain period of time. In the case of AUTO (see Figure 7), the first half of the preview is displayed OFF and the second half is displayed ON.

The scope sub backlight setting screen (b) has setting buttons corresponding to OFF, AUTO, and ON. OFF is a setting that keeps the backlight in the scope sub display 34 (see Figures 15 and 16) always OFF. AUTO is a setting that automatically switches ON/OFF using a dimmer function linked to the vehicle lights. ON is a setting that keeps the backlight in the scope sub always ON. When a setting operation is performed, the control unit 10 displays a preview for a certain period of time.

The scope sub-backlight color setting screen (c) has setting buttons corresponding to Aqua Blue, Yellow Green, Dark Red, Deep Blue, Green, Yellow Green, Orange, and Purple. When a setting operation is performed, the control unit 10 displays a preview for a certain period of time.
The scope sub semi-transparent mode setting screen (d) has setting buttons corresponding to ON and OFF. ON is a setting to display the scope sub-display 34 semi-transparently. OFF is a setting to not display the scope sub-display 34 semi-transparently. When set to semi-transparent display, the scope sub-display 34 is displayed so that the background image can be seen through.

The scope sub-additional information display setting screen (e) has setting buttons corresponding to ON and OFF. Additional information is information that is displayed in addition to the original display items in the scope sub-display 34. The control unit 10 starts displaying the additional information in the scope sub-display 34 approximately three seconds after detecting that the vehicle has stopped, and ends displaying the additional information when the vehicle starts moving.

The following additional information is set for some of the display items that can be set on the scope sub-display 34. This additional information includes the maximum and average values of the display items set on the scope sub-display 34. Note that this additional information is not saved while the power is off, and is the maximum or average value for the most recent drive since the power was turned on (the current drive).

The public enforcement automatic pop-up setting screen (f) has setting buttons corresponding to ON and OFF. ON is a setting in which a window is automatically displayed for a certain period of time when public enforcement information is changed. OFF is a setting in which the window is not automatically displayed even when public enforcement information is changed. Note that even when set to OFF, the control unit 10 displays the window when the MUTE button 223 (see Figure 1) is (manually) operated.
The in-scope clock display setting screen (g) has setting buttons corresponding to ON and OFF. ON corresponds to displaying the clock, and OFF corresponds to not displaying the clock.

■ 6.1.2 Tide information settings ■
As shown in Figure 23, when the control unit 10 detects operation of the tide information setting button on the standby setting screen A, it switches to displaying the tide information setting screen AB. Setting buttons corresponding to auto and manual are arranged on the tide information setting screen AB. When it detects operation of the manual button on this tide information setting screen AB, the control unit 10 displays a tide station setting screen (b) or the like on which tide stations such as Wakkanai, Abashiri, Ishigaki Island, and Yonaguni Island can be set.

■ 6.1.3 Graph Settings ■
As shown in FIG. 24 , when the control unit 10 detects operation of the graph setting button on the standby setting screen A, it displays graph setting screens AC1 and AC2. The two graph setting screens AC1 and AC2 are provided with setting buttons and manual setting buttons corresponding to the target data for which the graph is to be displayed. The target data includes speed ( FIG. 25 ), altitude ( FIG. 26 ), atmospheric pressure ( FIG. 27 ), acceleration ( FIG. 28 ), gyro ( FIG. 29 ), fuel consumption ( FIG. 30 ), temperature ( FIG. 31 ), RPM ( FIG. 32 ), engine 1 ( FIG. 33 ), engine 2 ( FIG. 34 ), fuel ( FIG. 35 ), and voltage ( FIG. 36 ). The manual setting button, as shown in FIG. 37 , allows multiple types of graphs (combinations of speed, altitude, and coolant temperature are exemplified) to be displayed according to the user's preferences. The altitude graph, as shown in FIG. 38 , displays differently depending on whether the mileage is less than 3 km or greater. In Fig. 1(a), which is a display example for distances less than 3 km, a graph of altitude from 0.0 km up to that point is displayed. In Fig. 1(b), which is a display example for distances 3 km or more, an altitude graph is displayed in two rows, upper and lower. The upper graph is a graph of altitude for the most recent 3 km of travel, and the lower graph is a graph of altitude from 0.0 km up to that point.

When the control unit 10 detects operation of the manual setting button on the graph setting screen AC1 as shown in FIG. 24 , the control unit 10 switches to displaying the manual setting screen (a). This manual setting screen (a) includes item buttons for setting target data and a cycle setting button for setting the sampling cycle. The item buttons display the names of the set target data, such as speed, forward/backward acceleration, and yaw. When the control unit 10 detects operation of the item button, the control unit 10 switches to displaying the target data selection screen (b). On the target data selection screen (b), data can be scrolled using the up arrow button (page forward button) and the down arrow button (page back button). The scrolled data includes speed, altitude, air pressure, instantaneous fuel consumption, current fuel consumption, coolant temperature, intake air temperature, engine speed, throttle opening, MAF, INJ, intake manifold pressure, remaining fuel, no graph, forward/backward acceleration, left/right acceleration, up/down acceleration, pitch, roll, and yaw. When the control unit 10 detects operation of the BACK button, it sets the target data selected on the target data selection screen as the selected data.
The manual setting screen (a) displays a cycle setting button corresponding to the target data selected on the target data selection screen (b). When the operation of the cycle setting button is detected, the control unit 10 switches to display a cycle selection screen (c) including cycle icons corresponding to cycles such as 500 ms, 1 s, 2 s, 5 s, and 10 s. The cycle selected on this cycle selection screen (c) is set as the sampling cycle of the target data.

■ 6.1.4 Auto item settings ■
As shown in FIG. 39 , when the control unit 10 detects operation of the auto item setting button on the standby setting screen A, the control unit 10 switches to display the auto item setting screens AD1 and AD2. The auto item setting screens AD1 and AD2 are screens for selectively setting the standby screens that the control unit 10 cycles through on the touch panel 15 when the AUTO button 302 (see FIG. 7 ) on the standby list screen 3A is selected. The auto item setting screens AD1 and AD2 include setting buttons for the clock, speed, eco-driving, acceleration, incline, digital meter, tide information, preset A screen, preset B screen, preset C screen, photo frame, graph, altitude, positioning information, fuel consumption meter, OBD data, and the like. Each setting button has an illuminated area at its left end. The control unit 10 illuminates the illuminated area of the setting button corresponding to the currently set item in green.

■ 6.1.5 Preset screen settings ■
As shown in FIG. 40, when an operation of the preset screen setting button on the standby setting screen A is detected, the control unit 10 sequentially displays one of the preset item setting screen AE1, GPS window interruption setting screen AE2, backlight setting screen AE3, backlight color setting screen AE4, semi-transparent mode setting screen AE5, and additional information display setting screen AE6. The standby screen set using these setting screens is stored and held by the control unit 10. There are three types of preset buttons, A to C, which correspond to the preset screens A to C, respectively. The same settings can be made for each preset screen. Three preset screen setting buttons are provided, corresponding to the preset screens A to C. The setting procedures for each preset screen setting button are all the same.

The preset item setting screen AE1 allows you to set preset items (display items) such as OFF, clock, vehicle speed, eco-driving, acceleration, incline, tidal information, satellite information, alarm panel, compass, reminder days, reminder distance, instantaneous fuel economy, average fuel economy, general road average fuel economy, highway average fuel economy, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow, engine water temperature, intake air temperature, outside air temperature, engine oil temperature, battery voltage, throttle opening, intake manifold gauge, boost gauge, tachometer, battery current, HV battery capacity, HV battery current, HV motor RPM, HV motor torque, and HV generator RPM. Note that of the above, items from instantaneous fuel economy onwards can only be set when OBD data is enabled. By default, the clock, speed, and eco-driving are set as preset A screen, acceleration, incline, and satellite information are set as preset B screen, and tidal information, compass, and barometric pressure are set as preset C screen. When a setting operation is performed, the control unit 10 displays a preview for a certain period of time. If the backlight is set to AUTO, the first half of the preview is displayed with the backlight OFF, and the second half with the backlight ON.

The GPS window interrupt setting screen AE2 has setting buttons corresponding to ON and OFF. ON is a setting that displays the type, distance, and direction of a GPS target when it enters the alarm range. OFF is a setting that does not display the type, distance, and direction of a GPS target even when it enters the alarm range. When the setting is ON and a GPS target approaches, a GPS window (display field) 391 displaying information about that target is displayed in an interrupt manner, as shown in Figure 41 (b). At this time, of the three ring displays 34 on the preset screen, the display positions of the left and right ring displays 34L and R are raised, thereby ensuring an interrupt area for the GPS window 391. Note that in the radar detector 1 of this example, the initial setting for the GPS window interrupt setting is ON.

The backlight setting screen AE3 has setting buttons corresponding to OFF, AUTO, and ON. OFF is a setting where the backlight is always OFF. AUTO is a setting where ON/OFF is switched by automatic determination. ON is a setting where the backlight is always ON. When the setting is made, the control unit 10 displays a preview for a certain period of time. The content of the automatic determination when AUTO is set differs depending on the flex dimmer setting. In the case of a flex dimmer based on a signal from the GPS receiver 121, it is ON when tunnel guidance is being performed without GPS positioning, and is OFF from sunrise to sunset at other times, and ON from sunset to sunrise. In the case of a flex dimmer based on signals from the illuminance sensor 127 and GPS receiver 121, it turns on when tunnel guidance is in progress without GPS positioning, and takes precedence over the settings of OFF from sunrise to sunset and ON from sunset to sunrise otherwise, and turns on when it is determined to be dark by the illuminance sensor 127. In the case of a flex dimmer linked to a vehicle illumination signal via the OBD function, it turns on when illumination is ON and off when illumination is OFF.

As shown in Figure 42, the backlight color setting screen AE4 has setting buttons corresponding to Aqua Blue, Yellow Green, Dark Red, Deep Blue, Green, Yellow Green, Orange, and Purple. When one of the setting buttons corresponding to a backlight color on the backlight color setting screen AE4 is operated, the control unit 10 displays a preview of the backlight color corresponding to that setting button for a certain period of time, and then switches back to the original backlight color setting screen AE4. The default setting is Aqua Blue.

As shown in Figure 43, the semi-transparent mode setting screen AE5 has setting buttons corresponding to ON and OFF. When the ON or OFF setting button on the semi-transparent mode setting screen AE5 is operated, the control unit 10 displays the preview screen corresponding to that setting button for a certain period of time, and then switches back to the original semi-transparent mode setting screen AE5. The preset screen (a) in Figure 43 is an example when semi-transparent display is set. In the preset screen (a), the ring display 34 is displayed semi-transparently so that the background image set as a custom image can be seen through it. The preset screen (b) is an example display where the background image of the ring display 34 is not visible through it. The semi-transparent mode is a display mode that respects the wishes of the user who set the background image as a custom image.

The additional information display setting screen AE6 has setting buttons for ON and OFF. The function to display additional information is only enabled when OBD is connected. When the vehicle speed obtained by the OBD function (OBD vehicle speed) remains zero for three consecutive seconds, a 17-segment scrolling display is performed, assuming that additional information is available for the set item. When the OBD vehicle speed exceeds zero, the display of additional information ends and the display returns to normal. Note that if the screen changes, it will start again three seconds later, even if the OBD vehicle speed remains zero for three consecutive seconds.

When the additional information display setting is ON, the control unit 10 starts displaying additional information on a portion of the meter approximately three seconds after the OBD vehicle speed reaches zero, and then returns to normal display when the vehicle starts moving. The display of additional information is executed under the control of the control unit 10 as shown in the example in Figure 44. The displayed additional information is the same as the additional information on the scope sub-display 34 described above, as follows:

Display items: Additional information

(1) Clock: Date, day of the week (2) Speed: Average speed (AVESPD), maximum speed (MAXSPD)
(3) Acceleration: Maximum forward acceleration (MAXFWD), maximum lateral acceleration (MAXL/R)
(4) Current fuel economy: Maximum current fuel economy (MAXAVE). Note that a NULL such as "-" is displayed until the current driving distance reaches 1 km.
(5) Moving average fuel consumption: Maximum moving average fuel consumption (MAXMOV). Note that until the mileage reaches 16 km or more (until the graph is filled up), NULL such as "-" is displayed.
(6) Fuel flow rate: Maximum fuel flow rate (MAXFLW)
(7) Engine water temperature: Maximum engine water temperature (MAXENG)
(8) Intake temperature: Maximum intake temperature (MAXITK)
(9) Outside temperature: Maximum outside temperature (MAXAMB)
(10) Engine oil temperature: Maximum engine oil temperature (MAXOIL)
(11) Throttle opening: average throttle opening (AVETHR), maximum throttle opening (MAXTHR)
(12) Engine load: average engine load (AVELOD), maximum engine load (MAXLOD)
(13) Intake manifold pressure gauge: Maximum intake manifold pressure (MAXINM)
(14) Boost gauge: Maximum boost pressure (MAXBST)
(15) Tachometer: Average RPM (AVERPM), Maximum RPM (MAXRPM)
(16) HV motor rotation speed: HV motor maximum rotation speed (MAX RPM)
(17) HV motor torque: HV motor maximum torque (MAXTRQ)

■ 6.1.6 Photo frame settings ■
The photo frame setting allows you to set up a photo frame standby screen that displays photos (JPEG data) stored on an SD card. By providing an SD card containing photo data, you can set up the photo frame standby screen without using a PC or other conversion tool. The photo frame standby screen sequentially displays up to 100 JPEG files stored in the /user/photo/ directory on the SD card. Subfolders are automatically searched up to four levels below /user/photo/. Photos stored on mobile phones and PCs are often organized in folders by date. This setting allows you to conveniently copy data organized in folders as is. JPEG files are supported in baseline JPEG or progressive JPEG YUV444/YUV422/YUV420/Y only formats. The maximum JPEG data size is 8000 x 8000 pixels, with a file size of approximately 3MB.

If the inserted SD card does not contain any photo data, the message "No valid JPEG files" will be displayed. The photo frame settings in this example do not have a function to fix one photo when there are multiple photos. One way to fix one photo as the standby screen is to turn off all items in the preset screen settings, thereby hiding the ring display 34. The photo frame settings may also include a setting to permanently display one photo. The photo frame settings may also include a function to set the order in which multiple photos are displayed.

When in photo frame standby mode, a clock is displayed in the upper right corner of the screen. It is possible to hide the clock by changing the settings. Note that when the photo frame is on standby, GPS target messages will not be displayed. However, volume control and radar and radio warning messages will still be displayed.

When the control unit 10 detects operation of the photo frame setting button on the standby setting screen A as shown in Figure 45, it sequentially displays one of the photo switching time setting screen AF1, photo switching effect setting screen AF2, photo zoom setting screen AF3, photo special effect setting screen AF4, and clock display setting screen AF5.
The photo changeover time setting screen AF1 has setting buttons arranged corresponding to photo changeover times of 3 seconds, 5 seconds, 10 seconds, 30 seconds, 1 minute, 5 minutes, and 15 minutes.
The photo switching effect setting screen AF2 has setting buttons arranged corresponding to no effect, fade, slide, window, zoom, and all (all effects). Fade is an effect in which the previous photo gradually disappears and the next photo appears. Slide is an effect in which the next photo slides in from the right. Window is an effect in which the next photo appears in a window-like shape from the center. Zoom is an effect in which the next photo enlarges and disappears, and then the next photo appears. "All" is an effect in which fade → slide → window → zoom → fade is executed repeatedly.

The photo zoom setting screen AF3 has setting buttons for each zoom setting: full, normal, normal no magnification, and forced screen size. Full is a zoom that enlarges or reduces the photo to fill the screen while maintaining the photo's aspect ratio. If the aspect ratio of the screen and the photo differ, the top and bottom or left and right sides will be cut off and some of the image will not be displayed. Normal is a zoom setting that enlarges or reduces the photo to fill the screen either vertically or horizontally while maintaining the photo's aspect ratio. If the aspect ratio of the screen and the photo differ, black bands will appear. Normal no magnification is a zoom setting that does not enlarge the photo when it is smaller than the screen size, filling the empty space with black in normal operation. Forced screen size is a zoom setting that enlarges or reduces the photo both vertically and horizontally to fit the screen size, which may result in the image being longer in landscape or portrait orientation. Note that the aspect ratio of the screen of the touch panel 15 in this example is 400:240 = 10:6.

The photo special effect setting screen AF4 has setting buttons for normal, negative, grayscale, and sepia.Normal is a setting without special effects, which displays the image as is.Negative is a special effect that displays the image in inverted brightness like a negative of a photo.Grayscale is a special effect that displays the image like a black and white television.Sepia is a special effect that displays the image in colors like an old photograph.
The clock display setting screen AF5 has ON and OFF setting buttons. By selecting either setting button, the user can set whether or not to display a clock in the upper right corner of the photo frame standby screen according to their preference.

■ 6.1.7 Fuel economy meter settings ■
The fuel consumption meter setting is a setting function for the fuel consumption planning screen as shown in FIG. 46. When the control unit 10 detects operation of the fuel consumption meter setting button on the standby setting screen A as shown in FIG. 47, it switches between displaying one of six fuel consumption meter setting screens AG1 to AG6. On the fuel consumption meter setting screens AG1 to AG6, setting buttons for data to be displayed as text are arranged on the left side of the fuel consumption planning screen as shown in FIG. 46. Each setting button is switched on and off each time it is operated. The left end of a setting button that is switched on is displayed in green.

To calculate braking mileage, for example, estimate the degree to which brake pad strain has been reduced based on the integrated value of power generated by brake regeneration current in hybrid or electric vehicles, and then calculate a distance less than the actual mileage based on that degree.

"0-20km/h Acceleration Time" displays the time taken to reach 20km/h from a stopped state in seconds. "0-20km/h Average Acceleration" displays the average time taken to reach 20km/h from a stopped state in seconds. "0-20km/h Shortest Acceleration" displays the shortest time taken to reach 20km/h from a stopped state in seconds. "0-40km/h Acceleration Time" displays the time taken to reach 40km/h from a stopped state in seconds. "0-40km/h Average Acceleration" displays the average time taken to reach 40km/h from a stopped state in seconds. "0-40km/h Shortest Acceleration" displays the shortest time taken to reach 40km/h from a stopped state in seconds. "0-60km/h acceleration time" displays the time taken to reach 60km/h from the most recent standstill in seconds.

"0-60km/h average acceleration" displays the average time taken to reach 60km/h from a stopped state in seconds. "0-60km/h minimum acceleration" displays the shortest time taken to reach 60km/h from a stopped state in seconds. "0-80km/h acceleration time" displays the time taken to reach 80km/h from the most recent stopped state in seconds. "0-80km/h average acceleration" displays the average time taken to reach 80km/h from a stopped state in seconds. "0-80km/h minimum acceleration" displays the shortest time taken to reach 80km/h from a stopped state in seconds. "0-20km/h driving time" displays the total time spent driving at 20km/h from a stopped state in hours:minutes:seconds format. "20-40km/h Ride Time" displays the total time spent traveling at speeds between 20km/h and 40km/h in the format of hours:minutes:seconds. "40-60km/h Ride Time" displays the total time spent traveling at speeds between 40km/h and 60km/h in the format of hours:minutes:seconds. "60-80km/h Ride Time" displays the total time spent traveling at speeds between 60km/h and 80km/h in the format of hours:minutes:seconds. "80km/h or above Ride Time" displays the total time spent traveling at speeds above 80km/h in the format of hours:minutes:seconds.

In addition to the data listed above, there is also "Illumination," which indicates the ON/OFF status of the illumination power line and is linked to the switch position for the parking lamps and above (including when the light is judged to be dim in AUTO); "Battery Current," which is the current value input and output to the battery, commonly called an ammeter, and is expressed as + when charging and - when discharging; "Engine Oil Temperature," which is the temperature of the engine oil, and is slightly higher than the coolant temperature because the engine is cooled by coolant; "Maximum Engine Oil Temperature," which is the temperature of the engine oil (SOC = State Of Charge); "Hybrid Vehicle Battery Capacity," which indicates the percentage of charge of the hybrid battery; "Hybrid Vehicle Battery Current," which is the current of the hybrid battery, is expressed as + when charging and - when discharging; "Hybrid Vehicle Motor RPM," which indicates the rotational speed of the hybrid motor; "Hybrid Vehicle Maximum Motor RPM," which indicates the maximum motor rotational speed after the ignition is turned on; "Hybrid Vehicle Motor Torque," which indicates the shaft rotational force of the hybrid motor; and "Hybrid Vehicle Torque," which indicates the maximum motor torque after the ignition is turned on. It is also a good idea to include "maximum motor torque" and "hybrid vehicle generator rotation speed," which indicates the rotation speed of the hybrid generator.

■ 6.1.8 OBD data setting ■
The OBD data setting is a setting function for the OBD data screen as shown in FIG. 48. When the control unit 10 detects an operation of the OBD data setting button on the standby setting screen A as shown in FIG. 49, it switches to display one of the OBD setting screens AH1 to AH6. The OBD setting screens AH1 to AH6 have setting buttons arranged corresponding to the following data. Each setting button is similar to the fuel consumption meter setting button in FIG. 47, and the left end lights up green when on. Data includes speed, average speed, maximum speed, 5-second speed, average 5-second speed, maximum 5-second speed, RPM, average RPM, maximum RPM, engine load, average load, maximum load, throttle opening, average throttle opening, maximum throttle opening, ignition timing, fuel level, intake manifold pressure, maximum intake manifold pressure, MAF, INJ, coolant temperature, maximum coolant temperature, intake air temperature, maximum intake air temperature, outside temperature, maximum outside temperature, engine oil temperature, maximum engine oil temperature, remaining fuel, fuel flow rate, maximum fuel flow rate, fuel consumed, lifetime fuel consumption, instantaneous fuel consumption, current fuel consumption, maximum current fuel consumption, lifetime fuel consumption, average fuel consumption, general road average fuel consumption, highway average fuel consumption, moving average fuel consumption, maximum moving average fuel consumption, driving time, driving These include driving time, idle time, idle ratio, mileage, lifetime mileage, 0-20km/h acceleration time, 0-20km/h average acceleration, 0-20km/h minimum acceleration, 0-40km/h acceleration time, 0-40km/h average acceleration, 0-40km/h minimum acceleration, 0-60km/h acceleration time, 0-60km/h average acceleration, 0-60km/h minimum acceleration, 0-80km/h acceleration time, 0-80km/h average acceleration, minimum acceleration, 0-80km/h minimum acceleration, 0-20km/h driving time, 20-40km/h driving time, 40-60km/h driving time, 60-80km/h driving time, 80km/h or higher driving time, lifetime engine mileage, and lifetime engine mileage ratio.

■ 6.2 Mode setting ■
The mode setting is a setting for an alarm mode with a different alarm frequency. As shown in FIG. 50, when the control unit 10 detects operation of the mode setting button on the setting list screen 1A, it switches the display to the mode setting screen B. The mode setting screen B has setting buttons corresponding to the normal, minimum, special, all-on, and manual alarm modes. The settings for each alarm mode except for manual mode, and examples of settings under manual mode, are shown in FIG. 51. Normal mode is the default mode when the product is shipped. In each mode except manual mode, the operation (on/off) corresponding to each alarm target is predefined. In manual mode, the user can manually set the operation corresponding to the alarm target. Minimum mode is a setting that alerts only to the minimum necessary alarm targets for all RD alarm functions, wireless alarm functions, and GPS alarm functions. Normal mode emphasizes the balance between functions, and in addition to the items in minimum mode, it alerts to items related to enforcement that are of high importance. Special mode is a setting that alerts to all items related to enforcement in addition to the items in normal mode.

When the control unit 10 detects operation of the manual setting button on the mode setting screen B as shown in Figure 52, it switches to displaying the manual setting screen BA, which has setting buttons corresponding to wireless settings, radar settings, and GPS settings.
As shown in Figure 53, when the control unit 10 detects operation of the radar setting button on the manual setting screen BA, the control unit 10 switches to displaying the radar setting screen. This radar setting screen has setting buttons corresponding to I-cancel, cancel sound, and reverse cancel. I-cancel is a function that automatically registers GPS location information when a false alarm occurs and cancels any further alarms at the same location. Cancel sound is a function that issues a voice message saying "Cancelling" once every 10 seconds during I-cancel. Reverse cancel is a function that cancels the RD alarm when passing a point where a radar speed camera or similar device is installed, if the installed lane is the opposite lane. Each setting button is toggled on and off with each operation, and the left end of a setting button that is toggled on is lit green.

When the control unit 10 detects operation of the wireless setting button on the manual setting screen BA as shown in Figure 54, it switches between displaying either the wireless setting screen (a) or (b). The two types of wireless setting screens (a) and (b) have setting buttons arranged corresponding to reception sensitivity, car location, enforcement, digital, special small, police station activity system, police phone, police activity, towing, helicopter TV, fire helicopter TV, fire, new ambulance, highway, and security. Each setting button is an on/off button whose left end lights up green when set to the on state.
When the control unit 10 detects an operation of the GPS setting button on the manual setting screen BA as shown in Fig. 55, it switches between and displays one of five types of GPS setting screens (a) to (e). The GPS setting screens (a) to (e) are provided with setting buttons corresponding to speed cameras, last-minute speed notifications, camera position notifications, passing notifications, speed limit notifications, speeding notifications, enforcement areas, checkpoint areas, speed limit change notifications, intersection monitoring points, red light ignorance prevention, highway traffic police, no-parking monitoring areas, stop sign warnings, N system, traffic monitoring systems, police stations, police boxes, accident-prone areas, vehicle theft areas, sharp curves, junctions and merging points, railroad crossings, ETC lanes, service areas, parking areas, highway oases, smart ICs, gas stations, tunnels, highway radio, prefectural borders, roadside stations, viewpoints, parking lots, fire stations, public restrooms, etc.

■ 6.3 Alarm settings ■
The alarm setting is a setting related to the mode of the alarm. When the operation of the alarm setting button on the setting list screen 1A is detected as shown in Fig. 56, the control unit 10 causes the touch panel 15 to display one of a radar reception sensitivity setting screen C1, a road selection screen C2, an alarm panel operation setting screen C3, and an alarm panel photo setting screen C4.
The radar reception sensitivity setting screen C1 has setting buttons corresponding to City, Extra, Super Extra, AAC/ASS, and AAC/SE. When the operation of any of the setting buttons is detected, the control unit 10 sets the radar reception sensitivity corresponding to that setting button.
The road selection screen C2 has setting buttons for ordinary roads, expressways, all roads, no auto air pressure, and with auto air pressure. The no auto air pressure setting is a setting in which the road is automatically determined by GPS, while the with auto air pressure setting is a setting in which the road is automatically determined by GPS and the air pressure sensor.

The alarm panel operation setting screen C3 has setting buttons corresponding to animation loop, animation → still, and still. The animation loop setting is an operation setting in which the animation loops while the alarm panel 36 (see FIGS. 12 and 15) is displayed. However, with this operation setting, the photo display on the alarm panel 36 is set to ON, and if there is a photo for the target, it switches to the photo midway through. The animation → still setting is an operation setting in which an animation is displayed for a while while the alarm panel 36 is displayed and then stills at the final frame. With this operation setting, the frequency of the alarm operation is reduced by the ring 340 when an automatic speed camera is not approaching. The still setting is an operation setting in which the alarm panel 36 is still at the final frame while it is displayed. With this operation setting, the alarm operation by the ring 340 when an automatic speed camera is not approaching is also still.
The alarm panel photo setting screen C4 has setting buttons corresponding to ON and OFF. When the ON setting button is operated, the control unit 10 sets the case where a photo of the target is displayed on the alarm panel 36. On the other hand, when the OFF setting button is operated, the target photo is no longer displayed on the alarm panel 36.

■ 6.4 Screen and LED settings ■
The screen/LED settings are settings related to the display screen of the touch panel 15 and the light-emitting operation of the multicolor LED 137. When an operation of the screen/LED setting button on the setting list screen 1A as shown in Fig. 57 is detected, the control unit 10 displays one of a brightness setting screen D1, a flex dimmer setting screen D2, a screen inversion setting screen D3, a window touch correction screen D4, a multicolor LED setting screen D5, and a button LED setting screen D6.
The brightness setting screen D1 has setting buttons corresponding to minimum, dark, normal, and bright.
The flex dimmer setting screen D2 has setting buttons corresponding to GPS, illuminance sensor + GPS, and OBD illumination interlocking. GPS is a dimmer setting that calculates sunrise and sunset times based on the time and latitude/longitude to determine brightness. Illuminance sensor + GPS is a dimmer setting that prioritizes brightness reduction determined by the illuminance sensor 127 in addition to GPS determination. OBD illumination interlocking is a dimmer setting that controls the illumination signal based on illumination detection from OBD information to daytime brightness when the illumination signal is OFF and nighttime brightness when the illumination signal is ON. Note that if the flex dimmer is installed in a vehicle that cannot detect the illumination signal, the control unit 10 disables the setting button corresponding to OBD illumination interlocking. Note that the initial setting for the dimmer setting is the OBD illumination interlocking dimmer setting when illumination is enabled with the OBD adapter connected, and the illuminance sensor + GPS dimmer setting otherwise.
The window touch correction screen D4 has an operation button arranged thereon for executing correction. When an operation of this operation button is detected, the control unit 10 switches and displays a series of correction screens in order, as shown in FIG.

The multicolor LED setting screen D5 has setting buttons for OFF, audio linkage, area linkage, and audio + area linkage. Using the multicolor LED setting screen D5, it is possible to set the operation of the multicolor LED 137 to four types. OFF is a setting where the multicolor LED 137 does not light up at all. Audio linkage is a setting where the color changes depending on the type of audio output, such as GPS alert, radar alert, or radio alert, and the brightness changes depending on the sound volume (amplitude) and dimmer.

The area linkage is a mode in which the multicolor LED 137 emits light in association with the area as follows.
Red: Orvis (2100m)
Yellow: Enforcement area (1100m/100m (stop)), checkpoint area (1100m), highway police waiting area (1100m), my area (1100m), intersection monitoring point (600m), red light ignorance prevention system (600m)
Both include targets inside the tunnel and just after the exit.

When area-linked, if you are heading in the above target direction and are within its valid range (including enforcement areas other than stop zones and checkpoint areas until you are out of range), the color of the "highest priority" will be output. The color conditions are the same as the system alert level. However, the 2100m for the above-mentioned speed camera is always extracted for highway attributes, but for general road attributes it depends on the "GPS target search range" setting. In this example, the blinking period is changed depending on the distance to the highest priority target. Specifically, the blinking period is determined by linear interpolation between the two points of 3000ms at 2000m and 750ms at 0m. The PWM ON time is fixed at 80ms, and the ON target value for the PWM brightness itself is 30% x dimmer coefficient. However, since these are target values, in reality, when it gets brighter, it moves by 1/2 the difference between the current value and the target value every 4 ms, and when it gets darker, it moves by 1/64 the difference between the current value and the target value every 4 ms, performing a process to bring them closer together, creating the illusion of the light fading away. Note that higher system warning levels are given priority.

Audio + Area Linkage is a setting that always prioritizes audio linkage output when the audio linkage conditions are met, and performs area linkage operation when the audio linkage conditions are not met. With this setting, the multicolor LED 137 turns off when the area linkage conditions are not met either.

■ 6.5 Audio settings ■
The audio settings are settings related to sound output such as warning sounds (alert voices), etc. When an operation of the audio setting button on the setting list screen 1A is detected as shown in Fig. 59, the control unit 10 displays one of a narrator switching screen E1, a voice mode setting screen E2, a radar warning sound setting screen E3, a radio warning sound setting screen E4, an Orbis location guide setting screen E5, a speed warning sound setting screen E6, a positioning announcement setting screen E7, a relaxation chime setting screen E8, a time signal setting screen E9, and an operation sound setting screen E10.

The narrator switching screen E1 has setting buttons arranged corresponding to the narrators Female 1, Female 2, Female 3, Female 4, and Male.
The voice mode setting screen E2 has setting buttons for normal, assistant, and advice. As shown in Figure 60, different sounds are generated depending on the selected mode. In the Best Partner+ (Plus) shown in the figure, in addition to conventional radio wave reception alerts, radar, radio, and GPS combined alerts are used. More accurate sounds are generated based on combined conditions of radio, radio, and GPS, rather than just radio alerts. Combined conditions for radio and GPS include changing the sound content of the radio alert only for the first time when radio waves are received within the speed trap area (500 m) after the speed trap area alert has started, and treating receiving radio waves after leaving the area and then re-entering the area as the first time. Note that the treatment of the first time is independent of the combined conditions for radio and GPS, described below. Best Partner+ sounds have the highest priority, so they will interrupt other sounds being played. Examples of voices include "♪ (same as stealth alert, Ayeen x 3) Speed measurement warning."

The combined radio and GPS conditions include a condition that changes the radio alert sound only "on the first occasion" when a specific radio signal is received within range (500 m) after the alert is initiated in a police or checkpoint area, and a condition that treats a radio signal received after leaving the area and then re-entering the area as a first alert. The "first occasion" is treated independently from the combined radio wave and GPS conditions described above. Note that this sound does not have the highest priority, so it will not interrupt other sounds being played. Target radio signals include car location proximity, car location distance, 350.1 police radio, digital radio, police signal, checkpoint signal, parallel tracking, special small radio, tow truck radio, police station activity radio, police phone, and police activity radio. If within a police tracking area, an example voice would be "♪ (preset radio jingle) Beware of police tracking."
In the radar detector 1 of this example, the timing of generating the warning sound (warning voice) is set as shown in FIGS.

The greetings in Fig. 60 include the greetings that are pronounced when GPS initial positioning is performed, etc. It is advisable to change the pronunciation content according to the date and time period as shown in Fig. 64.
The sunset announcement in Fig. 60 is sounded when the sunset time calculated from the vehicle position and weather output by the GPS receiver 121 arrives. An example of the voice is "♪ (GPS announcement jingle) It's sunset. Check your lights." Note that the sunset time changes as the vehicle moves, but once a sunset announcement has been made, it is best not to make another announcement until the power is turned off.

The reminder notification in Figure 60 is a notification display when a reminder has been set. If the number of days or distance has reached the set value at the time of activation, the notification display will be displayed up to three times (cancelled by operation). When this notification is made, a voice such as "♪ (reminder jingle) It's time to change the engine oil" is played, for example.
The speed camera countdown in the figure is a function that reads out the remaining distance when approaching a speed camera in 100m increments. Because the countdown sound does not have the highest priority, if other sounds are being made, it is possible that the distance has already been reached. Such distance sounds are canceled. The countdown is established when the sound count distance is equal to or less than 50m, but if multiple sound count distances are established at the same time (when the distance has increased), the closest one is output. Note that distances beyond the first countdown output will not be output. Once the separation distance is reached, it will be possible to output again from 900m or 400m. Sounds will not be made at 1000m or 500m.
In addition, to prioritize the countdown, the radar warning sound is temporarily changed. When the countdown is enabled, the radar warning sound setting temporarily switches to an electronic sound when the countdown state begins, and then returns to the set warning sound after the object has passed (radar warning sound countdown priority control).

Other audio-related functions include the following:
The low illuminance notification function is a function that sounds a sound when the surrounding brightness becomes dark using the illuminance sensor 127. Note that this may occur frequently in a series of tunnels, so it is recommended to set it so that the notification does not sound if the brightness changes from dark to bright within 30 seconds. For example, the voice output may say, "♪ (jingle) The illuminance has decreased. Please check your lights."
The eco-driving notification function sounds when the eco-driving points reach full points or when the points decrease. For example, it outputs sounds such as "♪ (jingle) Your eco-driving points are full points" or "♪ (jingle) Your eco-driving points are decreasing."

The OBD function also provides audio output. Regarding the outside temperature, a sound is emitted when the temperature is above 30°C, and once emitted, it will not be emitted again until the power is turned off. For example, the audio output is "♪ (jingle) The outside temperature is above 30°C." Regarding the throttle opening, a sound is emitted when the throttle opening is above 80% for three consecutive seconds, for example, "♪ (jingle) You're pressing the accelerator too hard." Regarding the engine load, a sound is emitted when the throttle opening is above 80% for three consecutive seconds, for example, "♪ (jingle) The engine is overloaded." Regarding the engine speed, a sound is emitted when the engine speed is above 5000 rpm for three consecutive seconds, for example, "♪ (jingle) The engine speed is too high." Mode-independent audio functions include speed warnings and radio alarm sounds.

The radar warning sound setting screen E3 (FIG. 59) has setting buttons arranged corresponding to electronic sound, voice, quiet voice, melody 1, melody 2, melody 3, and melody rotation.
The wireless alarm sound setting screen E4 has setting buttons for Voice, Demodulation, Voice Classic, Demodulation Classic, and OFF. As shown in Figure 65, in addition to the wireless jingle (Pirorororon), an electronic jingle can be selected as the wireless alarm. The electronic jingle sounds can be used to some extent to identify the type of wireless signal.
The speed camera location guide setting screen E5 has setting buttons corresponding to ON and OFF.

The speed warning sound setting screen E6 has setting buttons for OFF, chime, and voice. In this example, the speed warning sound is an electronic sound "king dong king dong...". When the speed warning sound and radar warning sound (electronic sound setting) are active simultaneously, the control unit 10 executes control to prioritize the radar warning (electronic sound setting). The speed warning is a function that sounds a speed warning chime when the vehicle speed is 110 km/h or higher (with a hysteresis setting of 5 km/h), regardless of the target speed limit. Because the chime is output as an electronic sound, it can be output simultaneously with other voices. When the radar warning is being output as an electronic sound, the radar warning takes priority. The speed warning sound can be turned ON/OFF on the speed warning sound setting screen E6 in Figure 59. The initial setting is OFF.

The positioning announcement setting screen E7 has setting buttons corresponding to ON and OFF.
The relaxation chime setting screen E8 has setting buttons corresponding to 30 minutes, 1 hour, 2 hours, and OFF.
The time signal setting screen E9 has setting buttons corresponding to ON and OFF.
The operation sound setting screen E10 has setting buttons corresponding to ON and OFF.

■ 6.6 Reminder settings ■
The reminder setting is a setting for the timing of maintenance such as oil changes. When the operation of the reminder setting button on the setting list screen 1A as shown in Fig. 66 is detected, the control unit 10 switches to and displays a reminder setting screen F on which setting buttons corresponding to oil, oil element, tires, and battery are arranged.
As shown in Fig. 67, when the control unit 10 detects operation of the oil setting button on the reminder setting screen F, it switches to the oil setting screen FA. When the control unit 10 detects operation of the oil element setting button, it switches to the oil element setting screen FB. When the control unit 10 detects operation of the tire setting button, it switches to the tire setting screen FC. When the control unit 10 detects operation of the battery setting button, it switches to the battery setting screen FD.
These setting screens, such as the oil setting screen FA, display the remaining distance and number of days until the oil change, and also have a change button. When the control unit 10 detects operation of the change button in the upper row, it switches to a screen (a) for inputting the distance until the oil change. When the control unit 10 detects operation of the change button in the lower row, it switches to a screen (b) for inputting the number of days until the oil change.

When considering hybrid vehicles, it is best to use the distance traveled with the internal combustion engine running (burning gasoline or diesel) (engine mileage) to determine the distance for oil and oil elements (reminder distance). In hybrid vehicles that have an engine and electric motor as their driving power source, the distance traveled by battery is unrelated to the deterioration of engine oil and oil elements, and the engine mileage excluding this can determine the actual distance required for maintenance. In vehicles other than hybrids, mileage = engine mileage, so it is possible to determine the distance for maintenance based on engine mileage, just as with hybrid vehicles.

■ 6.7 System Settings ■
When the control unit 10 detects operation of the system setting button on the setting list screen 1A as shown in Figure 68, it switches to display one of the log function setting screen G1, SD output setting screen G2, data erasure screen G3, demo mode setting screen G4, and version information screen G5.
As shown in FIG. 69 , the data deletion screen G3 has operation buttons corresponding to My Area, Cancel Area, Post Pin, Log Data, Eco Driving, and Initialization. When the control unit 10 detects operation of an operation button, it switches to display the corresponding deletion screen. For example, when it detects operation of the operation button corresponding to a post pin, it switches to display a post pin deletion screen that allows the user to select whether or not to delete the post pin. Each deletion screen, including the post pin deletion screen, has operation buttons corresponding to Yes and No. When it detects operation of the Yes operation button, the control unit 10 switches to display a deletion completion screen that indicates that the deletion has been completed. On the other hand, when it detects operation of the No operation button, the control unit 10 switches to display the original data deletion screen.

■ 6.8 Custom Settings ■
The custom settings are various detailed settings tailored to the user's preferences. When the operation of the custom setting button on the setting list screen 1A is detected as shown in Fig. 70, the control unit 10 switches between displaying a custom audio setting screen H1, a custom image setting screen H2, or a custom image zoom setting screen H3.
The custom sound setting screen H1 includes setting buttons corresponding to the following items: opening, speed camera jingle, GPS alert jingle, GPS notification jingle, radio jingle, GPS initial positioning, and radar melody 1. Each setting button switches between using a normal sound and a custom sound each time it is operated. Each setting button has a green light on its left end. The control unit 10 turns off the light for setting buttons set to use a normal sound and turns on the green light for setting buttons set to use a custom sound. Note that setting buttons corresponding to items for which no custom sound data file exists do not light up green even when operated. Furthermore, if a custom sound cannot be played for some reason, the setting button does not light up green even when operated. Note that if a custom sound data file is valid, the normal sound or custom sound set by that operation is output each time the setting button is operated.

The conditions for a file to be set as a custom sound are that it must be in MP3 audio format, have the file name as shown in Figure 71, and the path to the SD card where the file is stored must be \user\sound\. If the sound file is not mono, it will be played back in mono mixed format. To prevent alarm delays, playback is forcibly stopped after 15 seconds for all sounds other than the startup sound and radar melody 1 (Figure 71). For this reason, jingles and other sounds with short playback times are recommended. While the startup sound is playing, no other sounds other than electronic tones will be played until the startup sound has finished playing. To forcibly stop playback, the MUTE button 223 must be operated. Note that there is no automatic sound pressure adjustment function for the sound file. If the difference in sound pressure with the built-in sound is uncomfortable, the user must adjust the gain of the sound file. The built-in sound is adjusted to an average sound pressure of -13 dB.

In the default setting, if a replacement audio file is stored on the SD card, the left edge of the corresponding setting button on the custom audio output screen in Figure 70 will light green, and that custom audio will be checked. Operating the setting button corresponding to the target custom audio will toggle the check between ON and OFF. Operating ON will use the custom audio with the check ON, and that custom audio will be test played. Custom audio with the check OFF will not be used, and normal audio will be test played. Note that test playback can be stopped with the audio stop button.

The custom image setting screen H2 contains setting buttons for the startup screen and preset screens A through C. Operating each setting button allows you to set a custom image as the background for the corresponding screen (Figure 70(a) → Figure 70(b)). Custom image files must be in JPEG format, support YUV444/YUV422/YUV420/YUV411/Y Only sampling, and support baseline/progressive scanning. The maximum file size per image is approximately 3MB, the maximum resolution is 8000 x 8000 pixels, the file name is optional, the SD card path for storing files is \user\photo\, and the subfolder search range is \user\photo\ and below, up to four levels. Since the screen size is 400 x 240 pixels, if the image size does not match, it will be enlarged or reduced for display. In this case, you can select your preferred enlargement/reduction pattern using the custom image zoom setting screen H3 (Figure 70). For progressive JPEG files, only the final image will be displayed. If you add or delete files under \user\photo\, you will need to select an image.

The method for setting a custom image will be explained with reference to Figure 72. This figure illustrates the steps for setting a custom image on the startup screen. To set a custom image, first store a JPEG file under \user\photo on the SD card. Next, select the target screen by operating one of the setting buttons on the custom image setting screen. This will display a thumbnail list screen, from which you can select a photo to set as the custom image. The cursor will move to the currently set photo. You can scroll to the next page by operating the right triangle mark located at the bottom of the thumbnail list screen, and to the previous page by operating the left triangle mark. The upper left corner of the thumbnail list is the initial display. If the user prepares a logo of a vehicle manufacturer, etc., it is possible to set a photo of the manufacturer's logo as the startup screen, as shown in Figure 73.

The custom image zoom setting screen H3 (Figure 70) has setting buttons for Full, Normal, Normal No Enlargement, and Force Screen Size. Full is a zoom setting that enlarges or reduces the image to fill the screen while maintaining the aspect ratio of the photo. With the Full zoom setting, if the aspect ratio of the screen and the aspect ratio of the photo differ, the top, bottom, or left and right will be cut off. Normal is a zoom setting that enlarges or reduces the image to fill the screen either vertically or horizontally while maintaining the aspect ratio of the photo. With the Normal zoom setting, if the aspect ratio of the screen and the aspect ratio of the photo differ, black bars will appear. Normal No Enlargement is a zoom setting that, in normal operation, does not enlarge the image if it is smaller than the screen size, filling the empty space with black. Force Screen Size is a zoom setting that enlarges or reduces the image both vertically and horizontally to fit the screen size, which may result in the image being longer in width or height. The zoom settings selected on the custom image zoom setting screen H3 are not only reflected in the background settings of the actual startup screen/preset A, B, and C screens, but are also applied to the display of the custom image settings.

■ 6.9 OBD settings ■
As shown in Fig. 74, when an operation of the OBD setting button on the setting list screen 1A is detected, the control unit 10 switches to display the OBD setting screen I. This OBD setting screen I has setting buttons arranged corresponding to full tank start, full tank correction, coefficient correction, average clear, and all clear, and various operations are possible as shown in Fig. 75.

■ 7. Radarscope screen settings and operation ■
As described above, there are two types of radarscope screens: the map screen 31 (see FIG. 12) and the classic scope screen 32 (see FIG. 15). Here, we will explain in detail the settings and operation of the map screen 31, the operation of the classic scope screen 32, and the content of ring actions using the ring 340. The ring 340 is the outer frame part of the ring display 34 in the preset screen or the classic scope screen 32 (scope sub-display 34 in the case of the classic scope screen 32).
■ 7.1 Map screen settings and operation ■
Regarding the map screen 31, the control unit 10 executes the following setting process in response to an operation on the map mode setting screen (FIG. 20(b)).
When the operation of the "1 No Map Panel" setting button on the map mode setting screen is detected, the map screen 31 shown in Fig. 76 is set as the radarscope screen. The "1 No Map Panel" setting is a map mode for users who want to display a wide map and do not need to display an animation or photo warning panel 36.
When detecting the operation of the 1 Map Panel Automatic setting button, the control unit 10 sets the map screen 31 illustrated in Fig. 77 as the radarscope screen. The 1 Map Panel Automatic setting is a map mode for users who want to display a large warning panel 36 when approaching. When displaying the map screen 31 in Fig. 77 as the standby screen, the control unit 10 enlarges the warning panel 36 when the distance to the target is 600 m or less, and reduces the warning panel 36 when the distance is more than 600 m.
When the operation of the "Small Map Panel 1" setting button is detected, the map screen shown in Fig. 78 is set as the radarscope screen. The "Small Map Panel 1" setting is a map mode for users who want to display the alarm panel 36 but want to keep the alarm panel 36 at a small size because a large display would narrow the map area. In the radar detector 1 of this example, the "Small Map Panel 1" is set as the initial setting.

When the control unit 10 detects operation of the 1 map 2 small panel setting button on the map mode setting screen (Figure 20 (b)), the control unit 10 sets the map screen 31 shown in Figure 79 as the radarscope setting screen. If there is only one alarm panel 36, even if an important target is behind, closer targets or targets issuing an audio alarm will be displayed preferentially, which may make it difficult for the user to recognize the urgency of important targets behind. To address this situation, the 1 map 2 small panel setting is a map mode that prioritizes the display of important targets such as speed cameras, police, and checkpoints in the display position on the left side of the touch panel 15.

When 1 map 2 small panels is set, the control unit 10 draws a link line (a line segment serving as link information) 312 connecting the mini icon 383 in the mini radarscope 38 and the alarm panel 36 so that the user can accurately identify the target corresponding to the alarm panel 36. Furthermore, during an audio alarm, the control unit 10 flashes the corresponding link line 312 so that the user can immediately recognize the target.

When the control unit 10 detects operation of the setting button for no two map panels, it sets the map screen 31 shown in Figure 80 as the radarscope screen. In this map mode without two map panels, the control unit 10 divides the display screen of the touch panel 15 into two halves, left and right, displaying a detailed map 31A on the left side and a wide-area map 31B on the right side. The wide-area map 31B has a fixed scale and its orientation is fixed to heading-up. The scale and orientation of the detailed map 31A depend on the zoom setting and display format setting. In this map mode without two map panels, it is possible to display nearby targets on the detailed map 31A while also displaying distant targets on the wide-area map 31B. Note that the alarm panel 36 is not displayed in this map mode.

When operation of the setting button for the small 2 map panel is detected, the control unit 10 sets the map screen shown in Figure 81 as the radarscope screen. This map mode for the small 2 map panel is a map mode that adds the display of a small alarm panel to the map mode without the two map panels described above.

Here, the operational processing of the map screen 31 in FIG. 79 in the map mode of 1 map and 2 small panels will be described.
For the map screen 31 in the map mode of 1 map, 2 small panels in Figure 79, the control unit 10 sets the alarm panel 36 in the left display position to the high priority panel 36A, and sets the alarm panel 36 in the right display position to the low priority panel 36B. The control unit 10 assigns "GPS first priority" to speed cameras, police enforcement, checkpoints, my area, highway police, red light ignition prevention, intersection monitoring (yellow targets and above), etc., and displays them on the high priority panel 36A in the left display position (first display position) with high priority based on distance, target angle, and facing angle, regardless of audio output. The control unit 10 assigns "GPS second priority" to speed cameras, police enforcement, checkpoints, my area, highway police, red light ignition prevention, intersection monitoring, etc., which have the next highest priority after the targets displayed on the left, and displays them on the low priority panel 36B in the right display position (second display position).

However, when an audio target is detected, if it is not GPS first priority, the audio target will be displayed on the low priority panel 36B on the right, and if it is GPS first priority, it will be displayed on the high priority panel 36A on the left. Also, if neither an audio target nor GPS second priority is displayed on the low priority panel 36B on the right, other targets that are within the warning distance and angle (this is called GPS normal priority) will be displayed. Meanwhile, the mini radar scope 38 displays up to three targets: GPS first priority, GPS second priority, and GPS normal priority. However, if the same target exists, duplicate displays will be avoided.

GPS 1st/2nd priority begins displaying when the distance from the vehicle's position is long, and is unlikely to end display until the vehicle has passed. This setting increases the likelihood that GPS 2nd priority will be displayed with priority over GPS normal priority, allowing for more important targets to be displayed with greater reliability. Furthermore, when swapping the left and right display positions of an alarm panel 36 containing both animation and photos based on distance and angle conditions, the control unit 10 controls the display status to be maintained before and after the swap. This is a specification that takes into consideration the nuisance of always starting from the animation again. Furthermore, if RD reception or radio reception occurs, it is determined to have a higher priority than GPS 2nd priority, and is displayed on the low priority panel 36B on the right.

■ 7.2 Classic Scope Screen Operation ■
The scale of the classic scope screen 32 is controlled by the control unit 10 and is automatically changed according to the distance and facing angle of the focus target, as shown in Figures 82(a) to 82(c). When the scale is changed, it is controlled so as to zoom in and out smoothly.
A scope sub-display 34 surrounded by an annular ring 340 can be displayed in the upper left corner of the classic scope screen 32. This scope sub-display 34 has the same specifications as the ring display 34 on the preset screen, and performs the same display operation.
In the initial state, an alarm panel 36 is set as the scope sub-display 34, as shown in Fig. 82. When the alarm panel 36 is set as the scope sub-display 34, the scope sub-display 34 automatically disappears if no alarm event has occurred. On the other hand, as with the ring display, various display items can be set in the scope sub-display 34. Fig. 83 shows an example of the scope sub-display when vehicle speed and compass are set as the scope sub-display.

The position of the vehicle icon 322, which indicates the vehicle's position on the classic scope screen 32, changes in a stepped manner depending on whether the scope sub-display 34 is displayed and the position and type of the focus target. There are three horizontal positions for the vehicle icon 322: center of the screen, toward the right of the screen, and a position midway to the right. Furthermore, there are three vertical positions: bottom of the screen and top of the screen. By combining the three horizontal positions and the three vertical positions, there are six possible positions for the vehicle icon 322. The position of the vehicle icon 322 is changed appropriately so that the focus target can be displayed appropriately. When the position of the vehicle icon 322 is changed, the vehicle icon 322 does not suddenly move to a new position, but is displayed smoothly so that the vehicle icon 322 gradually approaches.

For example, if the focus target is located in the area to the right of the direction of travel, the vehicle icon 322 is located on the left so that the right-hand area can be displayed more widely, and if the focus target is located in the area to the left of the direction of travel, the vehicle icon 322 is located on the right so that the left-hand area can be displayed more widely. Furthermore, when the scope sub-display 34 is displayed in the upper left, the vehicle icon 322 moves to the right to utilize the remaining area. Furthermore, target icons for no parking areas, etc. are displayed in a central position in that area to indicate the enforcement area. When reporting that a no parking area, etc. has been passed (passage information), the vehicle icon 322 moves to the top of the screen so that the target icon for the no parking area, etc. located in the opposite direction of travel can be displayed.

As shown in FIG. 84 , the classic scope screen 32 displays a cross gauge 327 to clearly indicate the position of the focus target and to clearly indicate its movement when switching between them. This cross gauge 327 is composed of a horizontal line 327H that spans the entire horizontal area of the screen and a vertical line 323V that spans the entire vertical area, and they intersect at the position of the focus target. A lateral deviation 324H representing the horizontal component of the distance to the focus target is displayed at the upper end of the vertical line 323V. As shown in FIG. 84 , the lateral deviation 324H "13" displayed adjacent to the left of the vertical line 323V indicates that the focus target is offset 13 meters to the left of the vehicle position. A vertical deviation 324V representing the vertical component of the distance to the focus target is displayed at the right end of the horizontal line 327H. As shown in FIG. 84 , the vertical deviation 324V "796" displayed adjacent to the lower side of the horizontal line 327H indicates that the focus target is offset 796 meters forward of the vehicle position. When the focus target is switched between different targets, the cross gauge 327 does not immediately change position, but is displayed so as to approach the new target. At this time, the vertical deviation 324V and the horizontal deviation 324H display values that correspond to the position of the cross gauge 327. Such display control of the cross gauge 327 is effective for making it easier to grasp the new focus target when the focus target is switched.
For the target icon 326 of the focus target on the classic scope screen 32, a cursor 325 is displayed surrounding the target icon 326. This cursor 325 is animated and repeatedly enlarged and reduced in size during an audio warning for the target.

The control unit 10 controls the scope color (the display color of the scope surface) to change as needed while the classic scope screen 32 is displayed. The control unit 10 represents the system alert level with the color of the scope surface. In this example, the radar detector 1 allows the driver to determine the vehicle's status from the color of the scope surface on the classic scope screen 32. The scope color changes very smoothly. In this example, the radar detector 1 has 10 system alert levels (alert levels) as shown in Figure 85, with a color assigned to each level. The scope color on the classic scope screen 32 is set to a color corresponding to the target's system alert level. In the case of multiple targets, the level for which the highest condition is met is set as the system alert level, and that color is set as the scope color. Figure 86 shows an example of radio information (weak), in which the scope color is set to blue, corresponding to system alert level 1. Note that even when the scope color changes, the display colors of the crosshair gauge 327, vertical deviation 324V, and horizontal deviation 324H do not change, preventing the driver from losing sight of the focus target due to a change in scope color.

In this example, the classic scope screen 32 displays all public traffic enforcement information in a window, as shown in Figure 87, eliminating the need to follow long caption displays while driving. This window display is displayed on the front side of the classic scope screen 32. The public traffic enforcement window 32P is automatically displayed for 10 seconds when entering a city, ward, town, or village that has public traffic enforcement information posted to it, to display information about that city, ward, town, or village. Note that if the automatic public traffic enforcement pop-up setting is OFF, the public traffic enforcement window 32P will not automatically start displaying. If you want to see the public traffic enforcement window 32P again while it is hidden, press the MUTE button 223 to display the window again. In this way, when the display is started manually, the display state is maintained for one minute. Furthermore, if the MUTE button 223 is operated while the public traffic enforcement window 32P is displayed, the window can be immediately hidden. In this public traffic enforcement window 32P display, the current address, year, month, date, day of the week, etc. are displayed below the text display of the public traffic enforcement information. The above public enforcement window feature is only available when the Radarscope is set to Classic.

As shown in Figure 88, a triangular orientation mark 326M representing the monitoring direction is animated around the outer periphery of all target icons 326 displayed on the classic scope screen 32 that have a directional characteristic, such as a monitoring direction. The orientation mark 326M is displayed at a position that corresponds to the monitoring direction with the target icon 326 at its center, with the apex of the triangle pointing toward the monitoring direction. When a new target icon 326 appears on the classic scope screen 32, it flashes to attract the user's attention.

As shown in FIG. 89, a message window 32M is displayed at the bottom of the classic scope screen 32, displaying various information. The message window (display area) 32M displays the focus target icon, information corresponding to the target (if available), an arrow indicating the direction of the target as viewed from the vehicle, and the distance to the target (for targets not displaying a target icon 326 on the classic scope screen 32). The message window 32M for the GPS target shown in FIG. 89 displays the speed limit as information corresponding to the target. Note that for GPS targets corresponding to the icons in FIG. 90 that do not display a target icon 326 on the classic scope screen 32, the arrow and distance are omitted. The icons in FIG. 89 are, from left to right, for sharp curves, merging points, branching points, prefectural borders, ETC lanes, no-parking priority areas/high-priority no-parking areas, and high-risk areas for vehicle theft. Note that a speed limit icon is displayed at speed limit switching points.
Fig. 91 is an example of a message window 32M related to an RD alarm, and Fig. 92 is an example of a message window 32M related to a wireless alarm. In the message window 32M related to a wireless alarm, icons (display colors differ) shown in Fig. 93 are displayed in conjunction with text characters depending on the type of alarm.

On the classic scope screen 32, a status icon 35 (see Figure 84) is displayed in a flashing manner in the lower left of the screen. Examples of status icons 35 include a no parking area icon and an area with high rates of theft. The status icon 35 lights up brightly when the vehicle is located within a no parking area or other area so that it can be clearly identified, and lights up dimly even if the vehicle is outside the area. If the no parking area or high rate of theft area setting is turned off by mode or manual setting, the status icon 35 is completely turned off. When the message window 32M is not displayed, the status icon 35 is displayed in the lower left corner of the classic scope screen 32, and when the message window 32M is displayed, it is displayed above the left edge of the message window 32M. Note that on standby screens other than the classic scope screen 32, a similar status icon 35 is displayed in a flashing manner in the upper left corner of the screen.

■ 8. Preset screen ■
■ 8.1 Ring display ■
A maximum of three ring displays 34 (see FIG. 41) can be set on the preset screens A to C. The following describes the settings of display items that can be set on the ring displays 34. The scope sub-displays 34 (see FIGS. 15 and 16) on the classic scope screen 32 have the exact same specifications as the ring displays 34.

Display items that can be preset on the ring display 34 include a clock, vehicle speed, eco-driving, acceleration, incline, tide information, satellite information, alarm panel, compass, barometric pressure, reminder days, reminder distance, instantaneous fuel economy, average fuel economy, general road average fuel economy, highway average fuel economy, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow, engine water temperature, intake air temperature, outside air temperature, battery voltage, throttle opening, engine load, intake manifold gauge, boost gauge, and tachometer. Of these display items, vehicle information can only be selected when the OBD is connected. In addition to these display items, additional settings may be made, such as engine oil noise, battery current, hybrid battery capacity, hybrid battery current, hybrid motor RPM, hybrid motor torque, and hybrid generator RPM.

When an alarm panel 36 is set in the ring display 34, the same display operation as when the alarm panel 36 is set in the above-described scope sub-display 34, and a ring action by the ring (outer periphery) 340, are performed. In this way, in the radar detector 1 of this example, the scope sub-display 34 in the classic scope screen 32 and the ring display 34 of the preset screen have the same specifications. The reference numeral 34 is set for both the scope sub-display and the ring display. Regardless of whether the classic scope screen 32 or a preset screen is set as the standby screen, the same alarm notification operation can be received as long as the alarm panel 36 is set in the scope sub-display 34 or the ring display 34.
The following describes display items that can be set in the ring display 34. The contents of the display items are the same for the scope sub-display of the classic scope screen 32.

As shown in Fig. 94, the clock display has the left display mode when the semi-transparent mode is not selected on the mode setting screen (see Fig. 43), the center display mode when the semi-transparent mode is selected, and the right display mode when additional information is set on the additional information setting screen (Fig. 40). In the display mode when the semi-transparent mode is selected, the background image is displayed so that it can be seen through. In the clock display, the month, date, and day of the week are set as additional information.
For the vehicle speed display, average speed (AVESPD) or maximum speed (MAXSPD) is set as additional information. When either additional information is set to be displayed, the vehicle speed display will be as shown in FIG. 95. Note that the vehicle speed display and each of the following display items can also be selectively set to semi-transparent mode. The display mode when semi-transparent mode is selected and the display mode when it is not selected are the same as those for the clock display.

In the eco-driving display of Figure 96, points are displayed as a radar chart with sudden acceleration on the top, sudden deceleration on the right, idling on the bottom, and economical speed on the left. Each point is displayed with an upper limit of 100 points and a lower limit of 0 points. Each point has an initial value of 70 points, and points are deducted when the acceleration output from the acceleration sensor 124 and the speed output state from the GPS receiver 121 become an output state that is determined not to be eco-driving, and points are added when the output state becomes an output state that is determined to be eco-driving. The eco-driving display displays the numerical value of each point and a graph plotting that value on a radar chart.

As shown in Figure 97, the acceleration display features a meter for FR (forward/reverse acceleration) and a meter for LR (left/right acceleration). For forward/reverse acceleration, the F side is displayed as a negative value and the R side is displayed as a positive value. For left/right acceleration, the L side is displayed as a negative value and the R side is displayed as a positive value. Each meter has a first needle on the outer circumference and a second needle on the inner circumference. The first needle moves to a position equivalent to a maximum of 0.5 G and a minimum of -0.5 G, and holds if it exceeds this range. The second needle rotates at 0.03 G/360° (one revolution) to indicate changes in acceleration. This second needle rotates clockwise, with positive acceleration. Additional information set for the acceleration display includes the maximum forward acceleration (MAXFWD) and the maximum left/right acceleration (MAXL/R), which is the maximum absolute value of the left/right acceleration. Selecting either additional information will result in an acceleration display like the one shown on the right of Figure 97 (A).

In the tilt display of Figure 98, the vehicle's tilt of 30 degrees forward, backward, left, and right is displayed as a sphere. A detailed display, as shown in Figure 98 (B), is available for this tilt display. The tilt display is triggered when the output value of the vehicle's lateral acceleration (either rightward or leftward) from the acceleration sensor 124 reaches 0.1 G or greater. The upper white hemisphere of the spherical image in Figure 98 (A) becomes transparent, and the lower black hemisphere is displayed in gray. Then, as shown in Figure 98 (B), a white disk of the same radius as the hemisphere is drawn on the top surface of the lower hemisphere (the boundary surface between the upper and lower hemispheres (the surface passing through the equator)), and an image of a 3D car object placed on top of it is displayed. This 3D car object is rotated on the top surface of the lower hemisphere in accordance with the current heading direction detected by the geomagnetic sensor 126. In this detailed display, the vertical direction into the screen is north, the vertical direction toward you is south, the horizontal direction to the right of the screen is east, and the horizontal direction to the left of the screen is west. When the car inside the ball is heading due north, the taillights are displayed parallel to the screen, making the entire taillight side visible. In Figure 1B, red markers are displayed in vertical bands around the periphery of the disk, indicating the direction of travel. The right image in Figure 1B shows the car facing south-southeast, with the front of the car facing slightly to the right and the marker positioned slightly to the right. This display continues for three seconds after the output value of the acceleration sensor 124 in the vehicle's lateral direction (either rightward or leftward) falls below 0.1 G, and then returns to the display in Figure 1A. When a turning movement is detected based on a certain level of lateral G, the car inside the ball becomes visible for a certain period of time, and the turning movement is represented. In this way, the turning situation can be confirmed using the detailed display (B).

The tidal information display in Figure 99 shows tide levels calculated based on data, rather than measured quantities. The tidal information display first displays the name of the tide observation station closest to the current location, the moon phase for the current date, and the tide name, as shown in Figure (A). The tidal information display then cycles through the following displays every 10 seconds, as shown in Figure (B), including the name of the tide observation station closest to the current location, the moon phase for the current date, and the tide name (left image), the time and tide level of the first low tide of the day, the time and tide level of the first high tide (middle image), and the time and tide level of the second low tide of the day, the time and tide level of the second high tide (right image).

In the satellite information display of Figure 100, a grid is displayed with the vehicle's position at the center, with the top representing north, the bottom representing south, the right representing east, and the left representing west. The grid is configured with three concentric circles of different radii centered on the vehicle's position, and lines passing through the center in the left-right and up-down directions (although no lines are drawn within the smallest concentric circle). In the satellite information display, a circular satellite object is drawn at a position corresponding to the satellite's position acquired by the GPS receiver 121. After three seconds of display, the satellite numbers are displayed periodically, one satellite at a time, as shown in Figure 100 (B). That is, after all acquired satellites are displayed at their corresponding positions as shown in Figure 100 (A), after three seconds have elapsed, the first satellite number (18 in the figure) is displayed as shown in Figure 100 (B). The display time per satellite is three seconds, and after all satellite numbers have been displayed, the display returns to the original display as shown in Figure 100 (A). This display operation is repeated. It is recommended that the satellite information display be a heading-up display with the vehicle's direction of travel facing upwards. With this heading-up satellite information display, the displayed satellite positions will also change when the vehicle turns. It is recommended that the display color of each satellite be displayed in stages according to the C/N. For example, the display colors could be numbered 0 to 5 (0: red, 1: pink, 2: orange, 3: yellow, 4: yellow-green, 5: green), and the display color determined using the formula Color Number = C/N ÷ 8 (display color 5 for numbers 5 or greater).

As shown in Figure 101, when an alarm starts, the alarm panel displays the alarm animation followed by a photo. However, if the alarm panel photo setting is OFF or for targets without photos, no photos will be displayed. Depending on the alarm panel operation setting, the animation will either continue or stop. Once a target has finished a certain amount of animation, after switching to another target, the animation will not start again from the beginning, but will start from the photo display. However, if the alarm panel photo setting is OFF or for targets without photos, the animation will start from the beginning.

Furthermore, the alarm panel display operates differently when there is no alarm between the ring display 34 on the preset screen and the scope sub-display 34 in the classic scope screen 32. In the case of the preset screen, when there is no alarm, the logo display shown in Figure 101 (B) is displayed. On the other hand, in the case of the scope sub-display 34 in the classic scope screen, once the alarm disappears and the logo display is displayed, the scope sub-display 34 itself disappears after a while.

In the compass display of FIG. 102, the direction is displayed based on the geomagnetism detected by the geomagnetic sensor 126, with the direction of travel of the vehicle being the upper direction of the screen.
The barometric pressure display is a display of the current barometric pressure, as shown in Fig. 103. In this example, the barometric pressure display shows a range from a minimum of 700 hPa to a maximum of 1050 hPa.
The reminder days display shows the number of remaining days set in the reminder, as shown in Figure 104. If no reminder is set or if the remaining days reach zero, "----" is displayed. The number of days shown in the figure is the number of remaining days for oil, oil filter, tires, and battery, from the top row.
As shown in Figure 105, the reminder distance display is selectable when the OBD is connected and displays the remaining distance set by the reminder. This reminder distance display is a subtraction trip meter that displays the remaining distance. If no setting is made or if the remaining distance reaches zero, "----" is displayed. Note that when the remaining distance is less than 10,000 km, units of 100 meters are displayed. The distances illustrated in the figure are, from top to bottom, oil, oil filter, tires, and battery. The reminder distance subtraction target is lifetime engine mileage for oil and oil filter, and lifetime mileage for tires and battery.

The instantaneous fuel economy display in Figure 106 displays instantaneous fuel economy in the range of 0.0 to 99.9 km/L. The needle indicates 5 km/L at the lower limit of the scale, 50 km/L at the upper limit of the scale, 0 km/L at the lowest point, and 100 km/L at the highest point. This scale specification is common to each fuel economy display in Figures 107 to 111. The lower section contains a numerical display and an indicator. This indicator indicates whether fuel economy is good or bad, and displays red for 0 to 5 km/L, a complementary red-to-yellow range for 5 to 10 km/L, a complementary yellow-to-green range for 10 to 30 km/L, and a green indicator (a circle resembling a lamp) for 30 km/L or above.
In the average fuel consumption display of FIG. 107, the average fuel consumption is displayed.
In the general fuel consumption display of FIG. 108, the average fuel consumption on general roads is displayed.
The highway fuel consumption display in FIG. 109 displays the average fuel consumption on the highway.

The current fuel economy display, as shown in Figure 110, shows the fuel economy since the radar detector 1 was turned on, as a number ranging from 0.0 to 99.9 km/L. The value may change suddenly if not enough time has passed since the radar detector 1 was turned on, but as time passes, the value will converge. It can be reset even with the power on by operating OBD Settings - Clear Average. Additional information on the current fuel economy display is the maximum current fuel economy (MAXAVE). This maximum current fuel economy (MAXAVE) display setting becomes effective once the mileage reaches 1 km after the radar detector 1 is turned on. This is because a short mileage may result in an extremely good value.
In the lifetime fuel efficiency display of FIG. 111, lifetime fuel efficiency is displayed.

The moving average fuel consumption display, as shown in Figure 112, is a moving average fuel consumption displayed in a range of 0.0 to 99.9 km/L. The upper row displays a bar graph showing the fuel consumed over a 2 km section. The bar graph has a maximum of 10 squares, each square being 25 cc high, allowing a maximum of 250 cc of fuel to be represented by one bar graph. Every 2 km traveled, the most recent section fuel consumption starts at zero, and the section fuel consumption of each existing bar graph moves to the right (older). Only the most recent section fuel consumption displays with its top edge flashing. Assuming that the section fuel consumption is an array of nine items (fuel[0] to fuel[8]) and the most recent section distance is dist, the moving average fuel consumption m, which represents the fuel consumption of the most recent 16 km, is calculated using the following formula:
(Formula 1)

Fuel consumption for the section is stored in non-volatile memory, so it will be carried over the next time the device is started. Carrying over fuel consumption for the section in this way means that it will differ from the current fuel consumption, and an irrelevant value will not be displayed even if the distance is short. Fuel consumption for the section is reset by clearing the average in the OBD settings. Additional information displayed with the moving average fuel consumption is the maximum moving average fuel consumption (MAXMOV). This maximum moving average fuel consumption (MAXMOV) displays the maximum value for the current trip, which becomes effective after driving 16 km after resetting.

As shown in Figure 113, the fuel flow rate display shows the fuel flow rate per minute, with numbers ranging from 0 to 999 mL/min. The bar graph is updated each time fuel consumption is acquired via the OBD function. Some vehicles have an OBD communication cycle of 5 Hz and others 1 Hz, and the graph update speed differs depending on the vehicle model. Each square in the bar graph represents 20 mL/min, and a single bar graph can display up to 200 mL/min. Fractions below 20 mL are displayed in different brightness levels. Furthermore, if the fuel flow rate remains zero for approximately two seconds, the words "FUEL CUT" will scroll from right to left. Additional information on the fuel flow rate display includes the maximum fuel flow rate (MAXFLW).

As shown in Figure 114, the engine water temperature display shows engine water temperature, with numbers ranging from -40 to 215°C. The needle is 0°C at the bottom of the scale (45° left), 80 to 105°C at the center (it barely moves within this 25°C range), -40°C at the bottom (53° left), and 160°C at the top (53° right). The same is true for the intake air temperature display (Figure 115). Additional information on the engine water temperature display includes maximum engine water temperature (MAXENG). Additional information on the intake air temperature display includes maximum intake air temperature (MAXITK).

The intake temperature display in Figure 115 shows the intake temperature in the range of -40 to 215°C. An additional display to the intake temperature display is the maximum outside temperature (MAXAMB).
The outside temperature display, as shown in Figure 116, shows the outside temperature, and the numbers are displayed in the range of -40 to 215°C. The needle is at its lowest point (53° left) at -30°C and at its highest point (53° right) at 60°C. Additional information on the outside temperature display is the maximum outside temperature (MAXAMB).

As shown in Figure 117, the engine oil temperature display shows the engine oil temperature in numbers ranging from -40 to 215°C. The needle indicates 0°C at the bottom of the scale (45° left), 100 to 135°C in the center (it barely moves between these 35°C), -40°C at the lowest point (53° left), and 190°C at the highest point (53° right). Additional information on the engine oil temperature display is the maximum engine oil temperature (MAXOIL).

The battery voltage display is as shown in Figure 118. The number is displayed in the range of 0.0 to 25.5 V. The needle is at its lowest point (53° left) at 0 V and at its highest point (53° right) at 25.5 V.
The throttle opening display, as shown in Figure 119, shows the throttle opening. Numbers are displayed in the range of 0 to 100%. One color segment of the circular graph represents 4%. Fractions of 4% are expressed by brightness. Additional information on the throttle opening display includes the average throttle opening (AVETHR) and maximum throttle opening (MAXTHR).
The engine load display is shown in Figure 120. The numbers indicate the engine load in the range of 0 to 100%. One color segment of the circular graph represents 4%. Fractions of 4% are expressed by brightness. Additional information on the engine load display includes the average engine load (AVELOD) and maximum engine load (MAXLOD).

As shown in Figure 121, the intake manifold gauge display shows the intake manifold pressure relative to atmospheric pressure (101.325 kPa). The numbers range from -1.01 to 1.54 x 100 kPa. The intake manifold gauge is designed for vehicles without a supercharger, and in such vehicles, it will never show a value greater than 0.0 except for running pressure. It approaches 0.0 at full throttle and reaches -1.01 at vacuum. The indicator at the bottom left of the number uses color to indicate pressure. This indicator is always lit, and is green for values below -1, complementary between green and yellow for values between -1.0 and -0.5, complementary between yellow and red for values between -0.5 and 0.0, and red for values above 0.0. Because the amount of change is large, the needle has an afterimage, making it easier to recognize the movement. Additional information on the intake manifold gauge display is the maximum intake manifold pressure (MAXINM).

As shown in Figure 122, the boost gauge display shows the intake manifold pressure relative to atmospheric pressure (101.325 kPa). The numbers range from -1.01 to 1.54 x 100 kPa. The boost gauge display is for vehicles with a turbocharger, and may display a value higher than atmospheric pressure due to the turbocharger. When the value exceeds 0.00, boost begins and the boost indicator in the lower left corner flashes. When the value is less than 0.00, it turns off. The indicator colors are 0.0: green, 0.0 to 0.5: green to yellow, 0.5 to 1.0: yellow to red, and 1.0 or above: red. Because the amount of change is large, the needle has an afterimage, making it easier to recognize its movement. Additional information on the intake manifold gauge display is the maximum boost pressure (MAXBST).

The tachometer display, as shown in Figure 123, shows engine RPM. The numbers range from 0 to 9999 rpm, and the needle moves to a position appropriate to the RPM, even if the RPM exceeds 8000 rpm. Even when the amount of change is large, the needle has an afterimage, making the movement easy to recognize. Additional information on the tachometer display includes average RPM (AVERPM) and maximum RPM (MAXRPM).

In addition, for hybrid vehicles, it is also a good idea to add the following: battery current display (Figure 124), HV battery capacity display (Figure 125), HV battery current display (Figure 126), HV motor RPM display (Figure 127), HV motor torque display (Figure 128), and HV generator RPM display (Figure 129). Additional information for the HV motor RPM display is the maximum HV motor RPM (MAXRPM). Additional information for the HV motor torque display is the maximum HV motor torque (MAXTRQ).

■ 8.2 Background Settings ■
For the preset A to C screens, a background image (e.g., a photo) can be selectively set using the custom image setting screen H2 (see FIG. 70) in FIG. 130. A background image can be set for each of the preset A to C screens. The custom image setting screen H2 has selection buttons corresponding to the startup screen and the preset A to C screens. For example, operating the selection button for the preset A screen displays a background image selection screen for the preset A screen, as shown in FIGS. 131 and 132. The image currently selected on this selection screen is set as the background image for the preset A screen. If there is no photo data in the folder (four levels deep) under /user/picture/, the default background is displayed. If there is photo data in the folder (four levels deep) under /user/picture/, the photo data is displayed as a thumbnail (see FIGS. 131 and 132). By touching or using the remote control to select the desired photo from the thumbnail display, that photo can be set as the background of the preset screen. When touched, a preview of the photo set as shown in the center image in FIG. 132 is displayed for several seconds. It should be noted that, on the custom image setting screen H2, it is also possible to select a background image for the startup screen by operating the selection button corresponding to the startup screen.

In this example, the radar detector 1 allows the user to set the number and display positions of the ring displays 34 displayed on the preset screen as appropriate. This specification allows for flexible response to the needs of users who wish to display a background photo. By selecting the item selection button in the custom image setting screen H2 of Figure 130, a screen is displayed for setting the display items, including turning them OFF, for the three ring displays 34 on the preset screen, as shown in Figure 133, which illustrates the case of preset A screen. By turning OFF the center ring display 34 as shown in the left column, or the center and bottom left ring displays 34 as shown in the right column, it is possible to set a preset screen that allows the background photo to be seen clearly.

As shown in Figure 134, an alarm panel 36 can also be set on the ring display 34 in the preset screen. Setting an alarm panel 36 on the ring display 34 allows alarms to be displayed using the ring display 34 on the preset screen, even when the standby mode is fixed on the standby/radarscope switching screen AA2 (see Figure 19) and switching from the preset screen to the radarscope screen is not performed. Figure 134 (a) shows an example of an alarm in which an animated image of the N system is displayed on the alarm panel 36 of the ring display 34 in the preset screen. Figure 134 (b) shows an example of an alarm in which a photo image of an automatic speed camera is displayed on the alarm panel 36 of the ring display 34 in the preset screen. Figure 134 (c) shows an example of an alarm when no alarm event has occurred, in which case the default wallpaper is displayed on the alarm panel 36. It is also possible to configure the device so that a preferred image can be set as wallpaper. Note that the visibility of photo and animated images may be reduced if the backlight is turned on at night. In such cases, it is also possible to configure the alarm panel 36 without a backlight. Note that even if the ring display 34 is on the preset screen, if the alarm panel 36 is set, the ring action described below will be executed. This will be explained later with reference to Figures 148 to 152.

■ 9. Ring display specifications ■
■ 9.1 Transparent display ■
The ring display 34 on the preset screen or the scope sub-display 34, which is a ring display on the classic scope screen 32, can be displayed in a semi-transparent mode, allowing the background image to be seen through. In the radar detector 1 of this example, semi-transparent display is achieved using alpha blending technology, which blends multiple images using a coefficient alpha. Alpha blending technology is a well-known technology in software for game development and the like.

In the case of the ring display (scope sub-display) 34 of the alarm panel 36 shown in Figure 135, as shown in Figure 136, it has a four-layer structure consisting of a gray back panel 36A, a photo panel 36B that displays a photo, an animation panel 36C that displays an animation, and a ring panel 36D that includes a ring 340. In the case of a preset screen, this four-layer layer structure is displayed in front of the background image. In the case of a classic scope screen 32, this layer structure is displayed in front of the scope surface. Of the display panels that make up the layer structure, the display state of the display panels other than the ring panel 36D changes depending on the control of the coefficient α. For the ring panel 36D, the coefficient α is always displayed at 100%, and the display state is fixed.

In non-transparent mode, the coefficient α of the back panel 36A is set to 100%, resulting in zero transparency for the background image. Meanwhile, in semi-transparent mode, the coefficient α of the back panel 36A is set to 25%, resulting in the background image being visible through the back panel 36A. Note that in semi-transparent mode, the coefficient α is set to approximately 25% rather than zero to create a moderate sense of transparency. Setting the coefficient α to zero would result in a loss of the eyeglass-like appearance, similar to glasses without lenses, and would not effectively create a sense of transparency. On the other hand, setting the coefficient α to 25% creates a difference in appearance between the area of the background image without the ring display 34 and the area of the background image visible through the back panel 36A of the ring display 34, creating the impression that the ring display 34 is being seen through, i.e., a sense of transparency. Just as fashion glasses do not appear "realistic" without lenses, setting the coefficient α of the ring display 34 to zero and fully transparent would result in a loss of the appropriate sense of transparency.

When the warning panel 36 is displayed, the photo panel 36B and animation panel 36C are both controlled by a coefficient α ranging from 0% to 95%. When displaying the photo panel 36B, the coefficient α of the photo panel 36B is set to 95%, while the coefficient α of the animation panel 36C is set to 0%. This results in a photo image being displayed on the warning panel 36. By reversing the relationship between the two coefficients α, an animation image can be displayed on the warning panel 36 instead of a photo. When switching from a photo image to an animation image, the respective coefficients α are smoothly increased and decreased to create the effect of a gradual transition from the photo image to the animation image.

In this example, the radar detector 1 sets a difference between the coefficient α value when displaying the photo panel 36B and the coefficient α value when displaying the animation panel 36C. The coefficient α is set higher for the photo panel 36B, thereby suppressing the degree to which the background image shows through. This is because, in the case of photographic images, which have a higher spatial frequency and tend to appear more "cluttered" than animated images, the degree to which visibility is reduced by the background image showing through is particularly pronounced when a photograph is set as the background image. On the other hand, in the case of animated images in which areas are painted in solid colors, the impact of the background image showing through is minimal, and the degree of reduction in visibility is low. Alternatively, the coefficient α may be appropriately adjusted depending on the distribution of spatial frequencies of the photo panel 36B, animation panel 36C, etc. For example, a lower coefficient α may be set for panels with high spatial frequencies. The spatial frequency of the panel may also be determined from JPEG data. It is also possible to set the coefficient α to a constant value for both the animation image and the photograph image. In this case, it is possible to ensure consistency in the transparency of the ring display 34.

■ 9.2 Additional information display ■
In the case of a ring display 34 that displays a clock, speed, or boost pressure (e.g., FIG. 137), the display has a layered structure including a base panel 34A that corresponds to the dial of the clock, hands 34C of the clock, and a scale 34B that indicates the increments (see FIG. 138). The transmittance of the base panel 34A is adjusted by controlling the coefficient α, while the hands 34C and scale 34B are displayed without being transparent. The coefficient α of the base panel 34A is adjusted to 25% in semi-transparent mode and 100% in non-transparent mode.

Additional information can be set for some ring displays, such as the ring display 34 that displays a clock or boost pressure. For example, in the case of the ring display 34 for vehicle speed (see Figure 95), maximum speed can be set as additional information. When displaying additional information, specific letters or numbers are displayed by selectively lighting up one of the multiple segments used to display letters or numbers, thereby displaying the additional information. Unlit segments are displayed dimly with a coefficient α = 25%, while lit segments are displayed brightly with a coefficient α = 90%. In this example display, all segments are displayed to varying degrees, while numbers and other characters are displayed using the bright segments.

The additional information begins to be displayed three seconds (a predetermined time) after the vehicle speed reaches zero km/h, and then ends when the vehicle speed exceeds zero km/h. The additional information is overwritten and displayed on the ring display 34 (see Figure 95). For example, in the case of vehicle speed, when the display of the additional information begins, an animation is executed to make the speedometer-like needle and scale disappear, as shown in Figures 139 and 140. This animation is an operation in which each part, such as the numbers and needles representing the scale, gradually shrinks toward its center, eventually becoming a dot and disappearing. The numbers on the scale shrink toward their respective centers (the positions corresponding to the center of gravity). The needles shrink around the needle's axis of rotation, becoming a dot at that center and disappearing. After that, the maximum vehicle speed is displayed as additional information, as shown in Figure 141.

If the display start time for the additional information is set to three seconds after the vehicle speed reaches zero, there will be enough time for the driver to shift their line of sight from the front to the display screen of the radar detector 1 after the vehicle has stopped, allowing them to enjoy the animation described above. When the display ends, if the additional information is immediately made to disappear when the vehicle speed exceeds zero, the display of the ring display 34 can be switched when the display screen of the radar detector 1 is within the driver's field of vision. When the display of the additional information ends, an animation operation opposite to the above animation operation is executed. In this animation operation, each scale and pointer appears as if springing from a single point and expands, and is displayed at a predetermined position and size.

■ 9.3 Ring Action ■
On the classic scope screen 32, as shown in Figures 142 to 147, a scope sub-display 34 surrounded by a circular ring 340 may be displayed in the upper left corner. Except when the scope sub-display 34 is set to OFF (hidden), the scope sub-display 34 displays one of the following depending on the setting: clock, vehicle speed, eco-driving, acceleration, incline, tide information, satellite information, alarm panel, compass, air pressure, reminder days, reminder distance, instantaneous fuel economy, average fuel economy, average fuel economy on ordinary roads, average fuel economy on expressways, current fuel economy, lifetime fuel economy, moving average fuel economy, fuel flow rate, engine water temperature, intake air temperature, outside air temperature, engine oil temperature, battery voltage, throttle opening, intake manifold gauge, boost gauge, tachometer, battery current, HV battery capacity, HV battery current, HV motor RPM, HV motor torque, and HV generator RPM. When the alarm panel 36 is set, the scope sub-display 34 is displayed when a warning voice (voice) is generated and is hidden when no warning voice is generated.

When an alarm sound is generated, the control unit 10 causes the ring 340 forming the outer frame of the scope sub-display 34 of the alarm panel 36 to perform a predetermined display operation and display various alarm expressions. Note that the same alarm expressions using the ring 340 also apply to the ring display 34 to which the alarm panel 36 in the preset screen is set.

The predetermined operations that the control unit 10 causes the ring 340 to perform when the alarm panel 36 is set on the scope sub-display 34 include (1) an arrow operation, (2) a rolling operation, and (3) a flash operation.
(1) Arrow Action As shown in FIGS. 142 and 143 , in the case of a visible target alarm panel 36, the target's bearing is animated three times each time the target is focused. FIG. 143 shows a ring 340. Each frame constituting the ring 340 represents a location whose color can be changed. In this example, such locations are arranged around the entire circumference of the ring 340, with gaps between them. In the figure, the white areas indicate bare areas, and the hatched areas indicate lit (colored) areas (specific locations). The arrow action includes a movement from (a) to (b) to (c) in the same figure, like a clock face, moving from both sides toward a specific location (c) located approximately halfway between 2 and 3 o'clock. In this example, the arrow action (a) to (b) to (c) is repeated three times, and then a specific location approximately halfway between 2 and 3 o'clock is displayed, thereby indicating the target's bearing.

The alarm panel 36 in this example has three possible operation settings: animation loop, animation → still, and still. With the animation loop setting, the operation (a) → (b) → (c) is repeated three times, after which the display (c) → (d) is alternately repeated, and the target bearing is displayed in an oscillating manner. With the animation → still setting, the operation (a) → (b) → (c) is repeated three times, after which the display is fixed at (c) and the target bearing is displayed. With the still setting, the target bearing is immediately displayed as a still display of (c) without going through the arrow operation.

(2) Rolling Operation As shown in Figures 144 and 145, a warning is given by rotating the ring during an RD (radar) warning, a radio warning, or from 350 m before the speedometer (from the time when the vehicle's speed notification begins) until the speedometer passes. In particular, during an RD warning, the rotation speed increases according to the warning level. This rolling operation is performed regardless of the warning panel operation setting.
(3) Flashing Operation As shown in Figures 146 and 147, the entire ring flashes several times in the case of a target with no direction, such as a vehicle burglary, a parking ticket, a speed limit change, a merging, etc. If the alarm panel operation setting is set to animation loop or animation → still, the flashing operation is executed, and if it is set to still, the entire ring is lit.
The display color of the ring action is set to a color corresponding to the type of "red,""yellow,""blue," or "green" (see Figure 4), which indicates the urgency (alert level) of the target of the alert.

Examples of ring actions when the alarm panel 36 is set on the ring display 34 on the preset screen are shown in Figures 148 to 152. Figure 148 is an example of an alarm for a directional GPS target, such as a loop-coil speed camera, where the direction to the target is displayed by an arrow movement. Figure 149 is an example of a radio alarm, where attention is drawn by a rolling movement. The display color at this time is set according to the type of radio (see Figure 85). Figure 150 is an example of an RD alarm, where the rotation speed of the rolling movement changes depending on the reception level. Figure 151 is an example of a notification for a directionless GPS target (merging). At this time, the entire ring 340 flashes by means of a flashing movement. The display color is set according to the type in Figure 4. Figure 152 is an example of an alarm when the distance to the speed camera is within 350 m. Caution is drawn by a high-speed rolling movement.

■ 10. Posting ■
According to the radar detector 1 of this embodiment, it is possible to post information relating to traffic monitoring activities to an external server.
■ 10.1 Data Specifications of Posted Information ■ The data specifications of the posted information by the radar detector 1 of this example are as shown in Figure 153. Note that in this figure, header information and the like required for communication are omitted. The posted information of this example is composed of a combination of product information (serial number, etc.) of the radar detector 1 for identifying the poster and posted pin information. The breakdown of each piece of data such as X, Y, A, etc. that makes up the posted pin information is as shown in Figure 154(a). Of the data in Figure 154(a), the contents of the T, R, and M data are as shown in Figures 154(b), 154(c), and 154(d).

Freshness information is information that indicates the time when the traffic monitoring activity of the posted subject was carried out. As shown in FIG. 154(c), a data value indicating freshness is specified depending on the time when the traffic monitoring activity of the subject was carried out. For example, if the posted information is about a traffic monitoring activity that is currently being carried out, the freshness value will be zero, and if the posted information is about a traffic monitoring activity that was carried out more than one week but within the last month, the freshness value will be 20. On the other hand, if the posted information is about a permanently installed speed camera or the like, the freshness data value will be 255.
The direction type information is information that supplements the enforcement direction included in the location information. The direction type information can be used to specify the enforcement direction for monitoring the opposite lane, as well as to specify whether the traffic monitoring activity is to the right or left side of the driving lane. For example, if the traffic monitoring activity is targeting the driving lane, the enforcement direction type will be 0x01, which is 180 degrees reversed from the traveling direction (direction of travel of the vehicle) of 0x02 in Figure 155. For example, when posting pin 44 (Figure 157) is registered in front of an speed camera installed in the central reservation, this means that the speed camera is set diagonally to the right of the driving lane. In this case, the enforcement direction type will be direction 0x10 in the same figure.

■ 10.2 Submission process ■
(1) Generation of posted information When the control unit 10 detects an operation of the MEMORY button 222 while the standby screen is displayed, it pops up four registration menu buttons 313 including a pin setting button on the screen, as shown in Fig. 156. The registration menu buttons 313 include a pin setting button for registering a posting pin 44 (Fig. 157), an ITY map button for displaying the latitude and longitude of the vehicle's positioning position at the time the button is pressed as a two-dimensional barcode, a My Area button for registering a My Area, and a Cancel button for canceling the registered area.

When the pin setting button is touched, the control unit 10, as shown in FIG. 157, sets a posting pin 44 at the current location on the map screen 31 and registers the posting target's location information (latitude, longitude, address, enforcement direction) and the pin registration time in the posting pin memory area. In this example, the radar detector 1 can register up to four posting pins in the posting pin memory area, so up to four posting pins 44 can be registered, from pin 1 to pin 4. In this example, all pins are empty, so pin 1 is set at the current location as the posting pin 44, and the current location information, pin registration date and time, etc. are stored in association with pin 1. Activity content information indicating the type, implementation, method, etc. of traffic monitoring activity is generated in response to subsequent user operations (FIGS. 161 to 163) and stored in the posting pin memory area.

When all four posting pins 44 have been registered and four pieces of posting pin information are stored in the posting pin storage area, a registration menu button 313 in FIG. 158 pops up in response to operation of the MEMORY button 222. Here, the registration menu button, which includes a message saying "Full of pins," indicates that the posting pin 44 cannot be registered.
In this example, since the police direction is essential information for posted information, the posting pin 44 cannot be registered when the traveling direction has not been determined by the GPS function. When the MEMORY button 222 is operated when the traveling direction has not been determined, the control unit 10 pops up a registration menu button 313 including a registration menu button indicating that the direction has not been determined (FIG. 159). Also, when the MEMORY button 222 is operated when positioning is not being performed by the GPS function, the control unit 10 displays a caption at the top of the map screen 31 indicating that a GPS search is in progress (FIG. 160).

When the control unit 10 detects a touch operation on the map screen 31, it displays the settings list screen 1A in the top row of Figure 161. This settings list screen 1A has various setting buttons arranged, including a post button for posting posted information. When the post button is touched, the control unit 10 switches to displaying the post pin menu J1 in the middle row of the figure. This post pin menu screen J1 is a screen in which a confirm button and a delete button are arranged for each posted pin. Note that for unregistered posted pins, both the confirm button and the delete button are displayed in a shadow and are inoperable. When the control unit 10 detects a touch operation on the pin confirmation button, it reads the posted pin information corresponding to that posted pin from the posted pin memory area. The control unit 10 then displays a pin confirmation screen J2, which displays text of the location information (latitude and longitude, address, police direction) and time information (pin registration date and time) from the read posted pin information, as well as a post button for starting the posting process. The generation of posted information is initiated in response to a touch operation on the post button.

The posting buttons include a registration posting button for posting pin information, and a delete posting button for requesting the deletion of posted information. A delete posting for deleting posted information is a posting made when the traffic monitoring activity corresponding to the posted information has already ended, etc., and is no longer being carried out. When the control unit 10 detects a touch operation on the delete posting button, it generates a code image 15C in which the posted information for the deletion request is recorded, and displays a posting screen J81 including this code image 15C on the touch panel 15.

As shown in Figure 162, when the control unit 10 detects a touch operation on the registration posting button on the pin confirmation screen J2, it appropriately displays posting screens J3 to J80 shown in Figure 162 and Figure 163 on the touch panel 15 depending on the type of traffic monitoring activity, etc. Posting screens J3 to J5 in Figure 162 are screens that generate activity content information (Figure 153) such as the type (category) of the traffic monitoring activity to be posted, its implementation, method, etc.

Posting screen J3 is a screen for selecting the type (category) of traffic monitoring activity. Posting screens J4 and J5 are screens for selecting the implementation and method of traffic monitoring activity. Here, the types of traffic monitoring activity include speed cameras, N systems, checkpoints, and enforcement. The variations in implementation and method of traffic monitoring activity differ depending on the type of traffic monitoring activity. For example, with the N system, there are no variations in implementation or method. On the other hand, for enforcement, there are variations such as speed traps and mobile speed cameras, and for mobile speed cameras, there are variations such as radar and stealth types. Whether or not the posting screen is displayed during the posting operation depends on the type of traffic enforcement activity, etc.

All posting screens J4 and J5, except for posting screen J3, which allows users to select the implementation method and method of traffic monitoring activities, have an "Other" operation button. When the "Other" operation button is operated, the control unit 10 confirms the activity content information stored in the posting pin memory area and immediately switches the posting screen to display. With this type of specification, the radar detector 1 of this example can relatively easily post detailed information such as "An Orbis has been installed" depending on a user's level of knowledge, even if the user does not know the differences between Orbis (speeding) methods. On the other hand, a user with a high level of knowledge who is familiar with the differences between Orbis methods can post highly detailed information by selecting one of the methods on the posting screen.

The control unit 10 adds the activity content information generated in response to user operations on the posting screens J3 to J5 to the posting pin information stored in the posting pin memory area. Except for posting screen J3, which selects the type of traffic monitoring activity to be posted, posting screens J4 and J5, which select the implementation method, method, etc., have operation buttons for selecting "Other" or "Unknown." The purpose of providing operation buttons for selecting "Other" on posting screens J4 and J5 is to simplify posting by users who are not very familiar with traffic enforcement, thereby encouraging more posting.

The posting screen J6 in Fig. 163 is an operation screen for inputting freshness information (Figs. 153 and 154) that indicates when the traffic monitoring activity to be posted was implemented. This posting screen J6 has an operation button for selecting currently ongoing, as well as operation buttons for within one week, within one month, and within three months. The control unit 10 adds the freshness information corresponding to the operation button selected on the posting screen J6 to the posting pin information stored in the posting pin storage area.
The posting screen J7, enlarged in Fig. 164, is a posting screen for selecting the type of enforcement direction. This posting screen J7 has operation buttons for "driving lane,""oppositelane,""rightdirection," and "left direction." Below each operation button, an intuitive illustration of the corresponding content is displayed. The direction type information (Figs. 153 to 155) corresponding to the operation button selected on the posting screen J7 is added to the posting pin information stored in the posting pin storage area.

When any operation button is operated on the posting screen J7, the generation of posting pin information (Figure 153) is completed. The control unit 10 reads the posting pin information from the posting pin memory area and adds product information (Figure 153) to generate posting information. Then, a code image 15C is generated with this posting information recorded, and as shown in Figure 163, a posting screen J80 including this code image 15C is displayed on the touch panel 15. A user wishing to post can simply photograph the code image 15C with a mobile device such as a smartphone (multi-function mobile phone) running posting software compatible with code images. The mobile device that photographed the code image 15C performs image processing to extract the code image from the captured image and read the posting information recorded in the code image 15C, and then sends the posting information to the server.

Registered posting pins 44 (such as those in Figure 157) can be deleted by pressing the Delete button on the posting pin menu screen J1 in the middle of Figure 161. When this Delete button is pressed, the deletion of the corresponding posting pin is completed, following a screen to confirm the deletion and a screen indicating that the deletion has been completed, as shown in Figure 165(a). By pressing the System button on the settings list screen 1A at the top of Figure 161, the data deletion screen can be switched to and displayed, as shown in Figure 165(b). By selecting the Post Pin button on this data deletion screen, it is also possible to delete the posting pin and the corresponding posting pin information all at once.

In this example, the radar detector 1 transfers the posted information to the mobile terminal via the code image 15C (Figure 163). Alternatively, the radar detector 1 and the mobile terminal may be connected in a communicable state via wireless communication such as Wi-Fi, and the posted information may be transferred. For example, when dedicated software is running on the mobile terminal, operating the post button displayed on the touch panel 15 of the radar detector 1 may post the posted information via the mobile terminal. To equip the radar detector 1 with Wi-Fi functionality, a Wi-Fi module or the like may be incorporated. The mobile terminal may be any mobile terminal with access point (tethering) functionality. If the radar detector 1 is capable of wireless communication with the mobile terminal, it may also be possible to receive posted target information via the mobile terminal. This makes it possible for the radar detector 1 to issue notifications and warnings about the posted target information.

■ 11. Summary ■
As described above, the radar detector 1 of this embodiment allows for a variety of settings to be configured by the user, making it a vehicle system that can precisely meet a wide range of user needs. For users who require detailed information, it can provide highly detailed, specialized information. On the other hand, for users who require information that is intuitively easy to understand, various features are incorporated to make it easier to understand the information. Furthermore, the alarm panel 36 can be configured for the information display area (ring display) for setting vehicle speed, etc., so that an alarm can be issued for users who want to set the vehicle information display screen (preset screen) based on the OBD function as the standby screen.

In particular, on the classic scope screen 32 (see Figure 13, etc.), targets around the vehicle are clearly displayed on the scope surface. On this classic scope screen 32, one of the targets is selected as the focus target, and information about that focus target is displayed. The focus target is marked with a cross gauge 327 or cursor 325, making it easy to tell at a glance which target is the focus target. This also makes it easy for the driver to understand while driving.

Information about the focus target is communicated using the display color of the scope surface, the scope sub-display 34, and the message window 32M. All displays are very easy to understand, allowing the information to be grasped intuitively. This radar detector 1, which allows various information to be grasped intuitively, is a system that can encourage drivers to concentrate on driving by providing appropriate support. Furthermore, instead of the default alarm panel 36, the scope sub-display 34 can also display a clock, vehicle speed, etc., according to the user's preferences. This radar detector 1 can respond precisely to a wide range of user needs, making it a useful system for a variety of users.

Preset screens (such as Figure 43) allow the ring display 34 to be set in up to three locations, allowing the user to set a wide variety of display items to the ring display 34 according to their preferences. The ring display 34 has the same specifications as the scope sub-display 34 of the classic scope screen 32, and it is also possible to set an alarm panel 36. Therefore, when the preset screen is set to standby, it is also possible to place the ring display 34 for the alarm panel 36 along with the ring displays 34 for vehicle speed and acceleration. By setting an alarm panel 36 to one of the ring displays 34, it is possible to receive notifications of monitoring information related to traffic monitoring activities even when the preset screen is fixed to standby.

In this example of radar detection 1, in which the ring display 34 and scope sub-display 34 are set to the same specifications, consistency of operation is ensured between the preset screen and the classic scope screen 32, improving ease of learning how to operate and ease of use. In particular, by adopting a circular display area for the scope sub-display 34, compatibility with the ring display 34, which displays information such as vehicle speed and acceleration on the preset screen, is improved, achieving common specifications. On the preset screen, setting an alarm panel 36 in one of the ring displays 34 does not create any sense of incongruity (see Figure 148, etc.).

The outer periphery of the scope sub-display 34 and ring display 34 is formed by a circular ring 340. In this example, the radar detector 1 is configured with a display action (ring action) that utilizes the ring 340, which also serves as the decorative frame of the scope sub-display 34. By using the ring 340, various movements can be expressed by moving the area displayed as if a lamp is lit, such as an arrow movement (e.g., Figure 142), a rolling movement (e.g., Figure 144), and a flashing movement (e.g., Figure 146). Incorporating movements easily detectable by the human eye into the notification action can reliably attract the attention of drivers and other users while driving, ensuring reliable communication of notification information. This reduces the need for drivers to pay attention to the radar detector 1 screen when no notification is being made, thereby focusing the driver's attention on the road ahead and improving safety. The display color of the ring 340 display action corresponds to the type of traffic monitoring activity being notified. Users who are familiar with the relationship between the type of traffic monitoring activity and its color can immediately understand the vehicle's driving situation at a glance at the color displayed by the ring action.

In addition, it is possible to set a background image prepared by the user on the preset screen (Figure 133, etc.). If an important photo is set as the background image, by setting one of the ring displays 34 to hidden, the display area of the background image can be enlarged to show the photo to passengers or to look at it yourself. Which of the three ring displays 34 is hidden can be set at will, so it is a good idea to set the hidden ring display 34 to display the important parts of the photo. It is also possible to select a semi-transparent display mode for the ring display 34. By selecting semi-transparent mode, it is possible to create a tasteful screen by allowing the background image to be seen through.

The map screen 31 allows users to set the number of map areas and the number of warning panel areas to their liking. This allows for a wide range of detailed support for users with various needs, such as those who want a larger map display or those who want warning panels to pop up when approaching a traffic monitoring location. In particular, when two warning panel areas are set (Figure 79), a link line 312 links the mini icon 383 on the mini radarscope 38 to the warning panel 36, making it easy to grasp the location corresponding to the monitoring information on the warning panel 36. The two warning panel areas have different priorities. Only information with a certain level or higher is displayed on the left warning panel. Important information is always displayed on the left warning panel, resulting in a display that is very easy for users to understand.

The alarm panel 36 displayed on the map screen 31 has the same specifications as the alarm panels that can be set on the scope sub-display 34 and ring display 34. Therefore, consistency in operation is maintained whether the map screen 31 is set to standby, the classic scope screen 32 is set, or a preset screen is set. In this way, the radar detector 1 of this example achieves consistent specifications that are very easy for users to understand.

This example is an example of a device that displays not only monitoring information related to traffic monitoring activities, but also road information related to roads such as forks and ETC lanes, and driving information such as parking lots, tourist spots, and scenic spots. It is also possible to display various information including location information, such as information about amusement parks, restaurants, gas stations, etc., in the map area or panel area. Furthermore, with the hardware configuration of this example, not only can monitoring information related to traffic monitoring activities be displayed, but various information including location information can also be displayed clearly on the map screen 31. The map screen 31 of this example is also suitable as a screen for displaying information other than monitoring information.
