JP7059456B2 - Road regulation position distance guidance system - Google Patents

Description

The present invention relates to a system that guides a vehicle traveling on a road, particularly a highway, to a distance from a current position to a road regulation position at a desired interval.

Conventionally, when driving on a highway, voice guidance such as "How many meters away there is traffic jam" or "How many meters away there are traffic restrictions" comes on the radio. This is because there is a broadcasting device in a specific position section, and the broadcasting device sends specific information as a distance from a certain position. It does not provide guidance at any time according to the exact position of the traveling vehicle.
Patent Document 1 discloses a "vehicle display device".
Citing paragraph number 0005 of Patent Document 1 below,
"To explain the present invention in association with FIG. 1, which is a claim correspondence diagram, the present invention includes a position detecting means 100 for detecting the current position of a vehicle, a destination setting means 101 for setting a destination, and a progress of the vehicle. A traveling direction detecting means 102 for detecting a direction, a traveling speed detecting means 103 for detecting a traveling speed of a vehicle, a static road information storing means 104 for storing at least static road information including a road map, and at least a traffic congestion. Dynamic road information input means 105 for inputting dynamic road information including road construction and traffic regulation, at least the traveling direction of the vehicle detected by the traveling direction detecting means 102, and the traveling speed detected by the traveling speed detecting means 103. And the movement input by the dynamic road information input means 105 according to the current traveling condition of the vehicle including the distance from the current position detected by the position detecting means 100 to the destination set by the destination setting means 101. Dynamic within the display range calculated by the display range calculation means 106 from the display range calculation means 106 for calculating the display range of the target road information and the dynamic road information input by the dynamic road information input means 105. The information extraction means 107 for extracting road information and the static road information around the current position of the vehicle detected by the position detection means 100 are read from the static road information storage means 104, and the information extraction means 107 is used for the static road information. It is provided with a display means 108 for displaying the dynamic road information extracted by the above in association with each other. "
Therefore, the display range of the dynamic road information is determined according to the current traveling condition of the vehicle (direction of travel of the vehicle, traveling speed, distance to the destination), and the dynamic road information (traffic congestion, road) in this range is determined. (Including construction and traffic regulations) is displayed.
This device is for the means of determining the display range.
Since the distance to the dynamic road information is visually confirmed, the distance is not directly indicated, so that the distance information cannot be easily obtained even by visually recognizing the road on the screen. It may be overlooked if it is not always visually checked, which is inconvenient for providing information at any time.

This will be described below with reference to the figure.

FIG. 4 is a diagram illustrating an embodiment of the operation of the road regulation position / distance guidance system according to the present invention. FIG. 4 describes an outline of the operation of the road regulation position / distance guidance system according to the present invention.
A car equipped with a road regulation position distance guidance system is running on the up route road and is in the current position. Roads, especially high-speed roads, have kilometer posts to indicate distance. Let's assume that the kilometer post KP at the current position is 150.10. Naturally, this value changes as the car runs. The car is about to reach a target position. There is a restricted position on the road in the meantime for construction and other reasons. In the example of FIG. 4, there is a construction regulation position on the up line, and the section is shown to be from 200.04 to 200.17 on the kilometer post display. The actual kilometer posts on the road are arranged in units of 0.1 km, but based on this, the data of the regulated section (computer registration data) can be expressed in as much detail as possible.
Since the car detects the direction of travel, it can be seen that the car is traveling on an up route in this case.
Then, at present, the distance from the car to the regulated position is 49.94 km to 50.07 km as the difference of the kilometer post on the road.
Road officials want to be aware of the distance to the regulated position at any time while driving the car.
However, there are many regulated positions on the road. It is necessary to give limited treatment to which of the restricted positions should be targeted by road personnel at the site where the road is driven. When displaying on the display screen, multiple displays can be displayed, but visual recognition is required, and if the road is complicated, it cannot be seen at a glance. Since viewing the screen interferes with driving, I would like to use the screen display as an auxiliary means. Voice notification does not have this drawback, but instead can only notify one thing at a time. Therefore, even in this correspondence, it is necessary to notify the limited restricted position in a simple notification form suitable for voice notification.

FIG. 5 is a diagram illustrating an embodiment of a voice guidance pattern for the operation of the road regulation position / distance guidance system according to the present invention.
As a simple notification form suitable for voice notification, the voice guidance pattern shown in FIG. 5 is shown in 5-A. As you can see in the example, it is simple as voice information such as "A regulated position was found in the monitoring distance range" or "There is a yyy regulation from xx destination to xy destination." For example, in the case of Fig. 4, it means that "there is an overtaking lane restriction from 49.94 km ahead to 50.07 km ahead." In 5-B, voice guidance conditions are shown. Here, under the fixed interval condition, guidance is provided at regular time intervals or distances. Under the variable interval condition, guidance is provided at small intervals as the vehicle approaches the regulated position.

FIG. 3 is a diagram showing an embodiment of an incident identifying means in the road regulation position / distance guidance system according to the present invention.
I mentioned earlier that I want to make voice notifications about the limited restricted positions. FIG. 3 describes this limitation. At 3-A, the car is currently traveling at the kilometer post KPR (t) position. The direction of travel is assumed to be uphill. There are numerous regulatory cases on roads, including roads that are not displayed. These are the data registered in the memory of the computer as a list of regulated cases. However, considering the destination of this car, the roads that it passes through are limited, so there should be few regulatory cases. The designation of the destination is included in the designation of the road range in the designation of the reading condition 1121 of the incident reading condition setting means 1120.
Considering the current date and time, past and future regulatory cases are not covered. It is only necessary to identify and respond to cases where the scope of the regulated case includes the current date and time. Suppose that there are four regulatory cases, including regulation A, regulation B, regulation C, and regulation D, including the surrounding area to the destination, and each kilometer post is shown.
If we limit the area from road regulation cases nationwide to the area to the destination, there will be extremely few regulation cases.
3-B outlines the limitation of regulatory cases.
Since R1 and R2 are specified in the route designation, they are limited to regulation A, regulation B, and regulation C. In the designation of all lists around the current location, everything from regulation A to regulation D is shown. In the destination designation, only regulation A and regulation B are shown. Here, in the designation that the determination of the regulation period agreement (the traveling date and time of the vehicle is included in the regulation period) is made, only the regulation B is applicable. Regulation A is out of range for the date and time. Alternatively, the regulation type or single designation can be limited to regulation A only. However, in this case, there is no target because the regulation period is also matched. It is also possible to specify the order of distance and the latest.
Various types of regulated species are shown in 3-C. All are common on the road.

FIG. 1 is a diagram showing an embodiment of a configuration of a road regulation position / distance guidance system according to the present invention. Further, FIG. 2 is a diagram showing an embodiment of the operation flow of the road regulation position / distance guidance system according to the present invention.
Using the operation flow of FIG. 2, the outline of the operation of the road regulation position distance guidance system according to the present invention will be described.
There are roughly two flows: road regulation case registration and regulation period management 200 described in the upper right, and regulation position distance guidance 300 described in the upper left.
In the road regulation case registration and regulation period management 200, if the regulation as shown in the regulation type of 3C in FIG. 3 has occurred or is expected to occur, each regulation case is registered in the regulation case registration memory 210 on the computer. To register with. The contents of the regulated case registration are the case name, road range (region, road, section), regulation period, regulation KP range (up / down), regulation type, registrant name (or / and ID), etc. Is entered, and the registration number and registration time are automatically entered. As a result, all of the regulation data exists in the memory. Registration can be performed on the registration screen of the display monitor 220.

Next, the conditions for performing the regulated position and distance guidance are input, and the guidance is performed.
In the restricted position / distance guidance 300, when the start 310 process is performed, the case reading condition setting 320 process is performed. Here, the setting described in the lower right is performed.
In the case reading condition setting 320 process, as the setting item of the reading condition 321, it is possible to specify and input a plurality of (incident) sequential correspondence, specific, regulated type, road range, and the like.
In multiple (incident) sequential correspondence, multiple incidents shown in the list are dealt with in the order of the list or in the order of closeness. Only those selected from multiple case lists are dealt with as specific. As for the regulated species, for example, by selecting and designating one of the regulated species shown in 3-C of FIG. 3, only the same regulated species are selected and dealt with. In terms of road range, for example, the Tomei Expressway, or the Tomei Expressway between Toyota and Nagoya, which is a part of the Tomei Expressway, will be designated. In addition, it is possible to specify by region, for example, it is possible to specify the western part of Shizuoka prefecture.
As the setting items of the voice output condition 322, there are designated inputs such as a voice guidance pattern and a voice guidance condition. Both are shown in 5-A and 5-B of FIG. 5, and have already been described. When the designation is completed, the process of determining whether the vehicle is inside or outside the regulation period 330 is automatically performed, and among the regulation cases registered in the regulation case registration memory 210, only the regulation cases in which the driving date of the vehicle matches within the regulation period are selected and limited. Will be done. Incident list display / specific / unspecified 340 processes are performed on the display screen in the vehicle, and all of the displayed cases can be specified or unspecified.

Since the preprocessing is now completed, the button of the execution run 350 step is pressed, or the traveling direction change detection 351 step is automatically performed first. Here, since the sensor detects the direction of travel, it is possible to know whether or not the direction has changed. Of course, rough direction detection such as up direction and down direction may be sufficient. Normally, they are running in the same direction, but if it is detected that the direction has changed, the process returns to the start 310 process and the process is restarted. If the direction does not change, the current position data acquisition step 352 on the road is performed.
The traveling direction / change detection 351 and the current position data acquisition 352 on the road can be performed in reverse order.
The position of this is determined by the GPS (Global Positioning System) and the inertial navigation system using the traveling speed, the traveling direction, and the traveling time.
In the former, the earth coordinate position is obtained, and in the latter, the direction and distance from a specific earth coordinate position are obtained. Of course, since the earth coordinate position is on the road, this position coordinate can be expressed by the value of the kilometer post determined on the road. Therefore, both can be represented by the value of the kilometer post.
The values and earth coordinate positions of all kilometer posts on the road are stored in the data memory of the center management device (or in-vehicle terminal) as a KP-earth coordinate position table. Data can be read into the in-car terminal as far as necessary up to the target position. If the KP-earth coordinate position table is used, the KP of the current position can be obtained in the current position KP value acquisition 353 with respect to the earth coordinate position of the current position. Next, the out-of-range determination 356 step is performed. If the car deviates from the assumed predetermined road from the position where the button of the execution run 350 process is pressed to the target position, it is out of the monitoring range, and the process ends at the end 359 process. For example, if you pass the target position or go out on an unexpected road in the middle, the obtained kilometer post value will indicate ahead of the target position or will be separated from the kilometer post in the road by a distance of more than 0.1 km. It will be. This is because there is usually kilometer post data at intervals of 0.1 km on a road, but if the user is away from the road, the distance from the predetermined kilometer post on the road is 0.1 km or more. In this way, the out-of-range determination is possible.

Next, the distance between the KP at the current position and the KP at the case position of the regulation is calculated by taking the difference in value. This is the process of calculating the difference between the current position and the incident position KP value 354.
Now that the distance is known, voice guidance is performed on the distance in the process of distance guidance 355 based on the already specified voice guidance pattern and voice guidance conditions. It is also possible to display it on the screen at the same time.
If there is an end instruction by a human, it will end at the end 359 process. Therefore, it is determined whether or not the end instruction has been given in the end instruction determination step 357. If there is no end instruction, measurement is performed until the time or distance specified in advance in the guide interval timekeeping / total distance 358 step is reached, and after that, the process returns to the traveling direction change detection step 351 and is repeated. This makes it possible to guide (especially voice) the distance to the regulated position at a desired time or distance. If you select the voice guidance pattern as described above, you can also guide the distance to the beginning and end of the regulated section.
The programs of these operation flows are stored in the control memory 410 (program memory), and other data such as registration data and measurement data are stored in the data memory 420. Based on this, the controller 400 (computer) controls these operations. The data memory 420 includes data such as the regulated case registration memory 210, the KP-ground coordinate position table, and the case reading condition setting.

Next, an example of the configuration of the road regulation position distance guidance system for performing the above operation flow will be described. FIG. 1 is a diagram showing an embodiment of a configuration of a road regulation position / distance guidance system according to the present invention.
The road regulation position distance guidance system 1000 is between the in-vehicle terminal 1100 and the in-vehicle terminal 1100 that voice-guides the distance along the road from the current position on the road of the vehicle running on the road to the regulation incident position on the road. It is equipped with a center management device 1200 for exchanging necessary data. If the scale of guidance is extremely small and everything can be done within the range of the in-vehicle terminal 1100, it may be possible to configure only the in-vehicle terminal 1100.

First, the configuration of the in-vehicle terminal 1100 will be described.
The passenger of the car uses the in-car terminal 1100 to make necessary settings. Settings are made using the input IF (interface) 1111 such as a keyboard or touch key on the screen of the terminal display 220A and the case reading condition setting means 1120 as the setting means. The case reading condition setting means 1120 corresponds to the case reading condition setting 320 step of FIG. As described in the explanation of the flow, the read condition 1121 and the audio output condition 1122 can be set here. The contents have already been explained in the case reading condition setting 320 process.
The operation program for setting is stored in the terminal control memory 1130, and the terminal controller 1140, which is a computer, operates according to this program. The set data is stored in the terminal data memory 1150. For example, the data set by the case reading condition setting means 1120 is stored in the terminal case reading condition setting memory 1153 in the terminal data memory 1150. As the structure of the memory, the in-vehicle terminal 1100 has a terminal memory, which is a terminal control memory 1130 which is a memory for storing an operation program which is a program for executing the operation of the in-vehicle terminal, and data necessary for the operation. , Or the terminal data memory 1150 for storing the data generated as a result of the operation. As described above, the terminal data memory 1150 includes a terminal regulation case registration memory 1151, a terminal KP-earth coordinate position memory 1152, a terminal case read condition setting memory 1153, a terminal voice guidance pattern memory 1154, and the like.

Next, after making the necessary settings, the passenger of the car will receive the regulation guidance as explained in the flow of the regulation position distance guidance in FIG. 2, but in reality, it is the in-vehicle terminal 1100. The processing in the center management device 1200 required for the processing has already been completed. The processing in the center management device 1200 will be described after the description of the processing in the in-vehicle terminal 1100 is completed.
When the setting is completed in the case reading condition setting means 1120, only the case list corresponding to the setting is selected. The setting data set in the case reading condition setting means 1120 is stored in the terminal case reading condition setting memory 1153 and used.
In the in-vehicle terminal 1100, the selected incident list is further limited by the incident list determination means 1161 which is the determination means 1160 and the regulation period inside / outside determination means 1162. The case list determination means 1161 selects only regulated cases that meet the conditions set by the case reading condition setting means 1120. Further, in the regulation period inside / outside determination means 1162, only those whose operation date and time by car (date and time on the driving day) are included in the regulation period of the regulation case are selected. In this way, the minimum necessary and sufficient regulatory cases are identified. When this is done, the operation program prompts the execution run by screen or voice, or the execution run is automatically performed. In the execution run, first, the traveling direction / change detecting means 1112 detects the traveling direction, and further detects the change in the traveling direction. This is the direction of travel, such as going up or down. A gyro sensor is generally used as the detection sensor, and it is possible to distinguish which direction the vehicle is traveling in, and therefore to distinguish between ascending / descending and even its change. If the traveling direction changes, the flow returns to the start 310 again. If the traveling direction does not change, the process of acquiring the current position data on the road 352 is started, which is performed by using the current position data acquisition means 1113. Specifically, the position is acquired by GPS or inertial navigation. Next, in the process of acquiring the current position KP value 354, the current position is converted into the KP position on the road. On the road, a kilometer post position is set along the road, and since the geographic coordinate position of that position is also known, the difference from that position can be known. Therefore, the current position can be expressed as, for example, 100.15 km. This is a position 50 m away from the 100.1 kilometer post point in the direction in which the numerical value increases. For this purpose, there is a KP value acquisition means 1171 as one of the calculation means 1170. In the KP value acquisition means 1171, the distance between the earth coordinate of the current position and the earth coordinate of KP is obtained as described above, and the KP value is calculated based on the distance difference from the latest KP. Here, the KP on the road and its earth coordinate value are stored in the terminal KP-earth coordinate position memory 1152 in the terminal data memory 1150.

Next, corresponding to the step of out-of-range determination 356, the out-of-range determination means 1173 in the calculation means 1170 determines whether or not the KP value at the current position is out of range.
If the KP value of the current position passes the route on the way to the destination, or if it exits from the middle, it passes the nearest kilometer post point on the road on the route to the destination, or that point. It should be larger than the kilometer post interval. For example, on a normal highway, the distance between kilometer posts is set in units of 100 m. In this case, if you are on the target road, you are between the front and rear kilometer posts, so 100m will not open for either kilometer post. However, if you go out of the target road, a further opening will occur, so you can judge that it is out of range.
However, while driving on the boundary near the interchange, the distance and curve may cause inconveniences in the direction of travel, the kilometer post value of the current location, and the out-of-range judgment, so if the current location is around the interchange, in front of the system. It is better to maintain the operation of and restart the voice guidance after leaving the surrounding area.

Next, since the KP value of the incident position, which is the regulated position, is known, the distance along the road from the current position to the regulated position can be obtained by taking a difference from the KP value of the current position.
This was the process of calculating the difference between the current position and the incident position KP value 354. As a means, this calculation is performed by the distance calculation means 1172 in the calculation means 1170.
The KP value of the case position is stored in the terminal regulation case registration memory 1151 in the terminal data memory 1150.
Since the distance has been obtained, voice guidance is performed by the process of distance guidance 355 and the output (guidance) means 1180. The terminal is based on the setting in the case reading condition setting means 1120 in the guidance information creating means 1181. Voice guidance pattern The distance information is fitted into the guidance pattern in the memory 1154 for guidance. Guidance information is output to the voice output means 230 (speaker) and the display 220.
The voice guidance pattern described in 5-A of FIG. 5 is stored in the terminal voice guidance pattern memory 1154.
After the voice guidance, corresponding to the process of the end instruction determination 357, the end determination means 1174 in the calculation means 1170 determines whether or not the end instruction is via the input IF 1111. The end instruction may be given from the center management device 1200 via communication.
If it is determined that there is an end instruction, the operation ends.
If there is no end instruction, timekeeping or measuring distance is performed by the guidance interval measuring / measuring distance means 1175, position measurement is performed at a desired interval, and distance guidance is performed.

Now that the explanation of the in-vehicle terminal 1100 has been completed, the center management device 1200 will be described. In a small-scale system, the entire system can be configured with only the in-vehicle terminal, but considering the fact that it is common to each in-vehicle terminal 1100 such as incident position data and KP-horizontal coordinate position data, and the scale becomes large, It is more convenient to include the center management device 1200 in the configuration.
The configuration of the center management device 1200 is not so different from that of the in-vehicle terminal 1100.
For the sake of distinction, the letters of the center are attached.
In the center management device 1200, the following registration can be performed by using the registration input means 1210 while looking at the center display 220B.
First, the kilometer post of the kilometer post point on the road and the data of the earth coordinate position can be registered and stored in the KP-earth coordinate position memory 1252. When there is a road regulation case, the case name, identification code, position represented by the numerical value of the kilometer post, regulation period, etc. can be registered and stored in the regulation case registration memory 1251. The voice guidance pattern memory 1254 can register and store usable voice guidance patterns. Incident reading condition setting The incident reading condition can be set in the case reading condition memory 1253.
Each of the above memories constitutes a center data memory 1250.
Of course, the settings can be modified or added. These operations are stored in the center control memory 1230 as an operation program, read by the center controller 1240, and executed.
The center management device 1200 and the in-vehicle terminal 1100 are connected by a communication means 1300.
Since the center management device 1200 stores the above data related to a large number of roads, the in-vehicle terminal 1100 reads only the data necessary for its own driving via the communication means 1300, and the terminal in the in-vehicle terminal. It can be stored and used in each memory in the data memory 1150.

It should be noted that the position data is transmitted to the center management device by communication without being read into each memory in the terminal data memory 1150, the operation performed by the above-mentioned in-vehicle terminal is performed by the center management device, and the guidance data is returned by communication. Other actions such as getting guidance are possible, but mutual communication is frequent and it is not a good idea. That is, as the configuration in this case, most of the configurations of the in-vehicle terminal 1100 of FIG. 1 are on the center management device 1200 side, and the in-vehicle terminal 1100 includes the current position data acquisition means 1113 and the traveling direction / change detecting means 1112. It has an input IF 1114 for the input means 1110 and the case reading condition setting means 1120, and other things are to be performed by the center management device 1200. As mentioned earlier, it is possible to have a small-scale system that does everything on the in-vehicle terminal side without having the center management device 1200.
Further, in the explanation of the process flow in FIG. 2, the flow as an entire system is described without separating the in-vehicle terminal 1100 and the center management device 1200. In FIG. 1, the means configuration is described separately for the in-vehicle terminal 1100 and the center management device 1200. Therefore, for example, in FIG. 2, the controller 440 is a terminal controller 1140 and a center controller 1240 in FIG. 1.
Similarly, the display 220 in FIG. 2 is a terminal display 220A and a center display 220B in FIG. 1. The control memory 410 in FIG. 2 is a terminal control memory 1130 and a center control memory 1230 in FIG. 1, and the data memory 420 in FIG. 2 is a terminal data memory 1150 and a center data memory 1250 in FIG.
When the case registration means 1114 on the road is provided in the input means 1110 of FIG. 1, the KP value is obtained at the position when the car is driven and the case position is reached, and this is used as the terminal regulation case registration memory 1151 or / and regulation. It is convenient to be able to register in the case registration memory 1251 and provide data for guiding other vehicles.

In the above explanation, the position measurement interval, the display interval, and the voice guidance interval are the same, but the display interval / voice guidance interval adjustment means is provided in the case reading condition setting means 1120, and the position measurement is different. It is natural that it can be as small as possible to thin out. That is, although the measurement is fine, the guidance can be performed with a rough feeling. Further, the voice guidance can be performed not always but when the voice guidance switch is pressed (selection with voice). By doing this, it is possible to limit the time when the voice is noisy to the required time as much as possible. Here, the switch can select the presence / absence of voice guidance or start voice guidance.
Of course, it is displayed so that it can be checked at all times. It is also convenient to display "voice" or "voice present" on the display surface when there is audio output, and conversely, "no audio" is displayed on the display surface when there is no audio output to be displayed.

As described above, the road regulation position distance guidance system according to the present invention limits the target road, the regulation position, and the period along the road traveling to the destination, and from the current position of the traveling vehicle to the regulation position. Since the distance can be measured at any time based on the difference in KP and voice guidance can be provided, it is extremely convenient for industrial use.
