[0042]
Next, a basic operation of the navigation system having the above configuration will be described.
[0043]
First, when the operation unit 34 is operated by the driver and the navigation device 14 is activated, a navigation initialization processing unit (not shown) of the CPU 31 performs navigation initialization processing, and the current location and direction detected by the GPS sensor 15. While reading the direction of the vehicle detected by the sensor 18, various data are initialized. The matching processing means (not shown) of the CPU 31 performs matching processing, and the current location is determined on which road link based on the read current location trajectory and the shape and arrangement of each road link constituting the surrounding road. The current location is specified by determining whether the current location is located.
[0044]
Subsequently, an information acquisition processing unit (not shown) of the CPU 31 performs an information acquisition process, and reads and acquires the navigation information from the data recording unit 16 or receives it from the information center 51 or the like via the communication unit 38. get. When acquiring from the information center 51, the information acquisition processing means downloads the received navigation information to a flash memory or the like. In addition, when the navigation information is acquired via the communication unit 38, the program can also be acquired.
[0045]
A display processing unit (not shown) of the CPU 31 performs a display process, forms a map screen on the display unit 35, and maps the vehicle position and a map around the vehicle position on the map screen based on navigation information. And the direction of the vehicle is displayed. Therefore, the driver can drive the vehicle according to the vehicle position, the map around the vehicle position, and the vehicle direction.
[0046]
Next, an operation when the navigation system is used for searching for a route will be described.
[0047]
First, when a driver inputs a destination by operating the operation unit 34 (FIG. 1), a destination setting processing unit (not shown) of the CPU 31 performs a destination setting process to set the destination. When the driver registers a predetermined point as a memory point in advance and selects the memory point as a destination, the destination setting processing means can also set the selected memory point as a destination. .
[0048]
In addition, since the destination set in this way is sequentially recorded in the RAM 32, the driver operates the operation unit 34 to set a predetermined destination from the destinations set in the past, that is, the destination history. When a place is selected, the destination setting processing means sets the selected destination again as the destination.
[0049]
When the destination is set in this way, the route search processing means (not shown) of the CPU 31 performs route search processing, reads the current location, the destination, etc., and reads the search data, etc. from the data recording unit 16, Based on the current location, the destination, and the search data, a route from the departure point represented by the current location to the destination is searched, and route data representing the searched route is output. When the driver inputs a point different from the current location as the departure point, the route search processing means searches for a route from the input departure point to the destination.
[0050]
Subsequently, a guidance processing means (not shown) of the CPU 31 performs guidance processing and guides the driver on the searched route, that is, route guidance. For this purpose, the route display processing means of the guidance processing means performs route display processing, reads the route data, and displays the searched route on the map screen according to the route data.
[0051]
If necessary, the voice output processing means of the guidance processing means performs voice output processing and outputs a search route by voice from the voice output unit 37 to perform route guidance.
[0052]
Incidentally, route search processing can also be performed in the information center 51. In that case, the CPU 31 transmits the current location, the destination, and the like to the information center 51. When the information center 51 receives the current location and destination, the route search processing means (not shown) of the CPU 54 performs the same route search processing, reads search data from the database 57, and based on the current location, destination and search data. Thus, a route from the departure point represented by the present location to the destination is searched, and route data representing the searched route is output. Subsequently, a transmission processing unit (not shown) of the CPU 54 performs transmission processing and transmits the route data to the navigation device 14. In the navigation device 14, when the information acquisition processing unit receives route data from the information center 51, the guidance processing unit performs route guidance as described above.
[0053]
In this way, route guidance is performed, and the driver can drive the vehicle according to the searched route displayed on the map screen.
[0054]
The navigation device 14 can receive traffic information, general information, and the like via the communication unit 38. For this purpose, the additional information acquisition processing means of the information acquisition processing means performs additional information acquisition processing, and receives and acquires the traffic information, general information, and the like as additional information. Therefore, the route display processing means displays additional information on the map screen.
[0055]
The traffic information specifies information type data indicating the type of information, secondary mesh X and Y data for specifying a secondary mesh as a mesh, and a road link connecting two points (for example, intersections). And link number data representing the uplink / downlink and link information representing the content of information provided corresponding to the link number data. The link information includes, for example, a traffic jam from the start point of the road link. Consists of traffic jam head data representing the distance to the head, traffic jam degree data representing the degree of traffic jam, traffic jam length data representing a traffic jam section from the head of the traffic jam to the end of the traffic jam, and the like.
[0056]
Therefore, the route display processing means converts each link information in the traffic information into, for example, a traffic congestion arrow as a traffic condition index indicating a traffic congestion index indicating whether the traffic is congested or not. The congestion arrow is displayed along the road on the map screen. In this case, the color of the road, the traffic jam arrow, etc. is changed to red, orange, etc. according to the degree of traffic jam.
[0057]
In this manner, the driver can know the traffic jam situation on the route on which the vehicle is to travel, the searched route, and the like.
[0058]
By the way, in setting the memory point as the destination, the display processing unit forms a destination search screen d1 as shown in FIG. 2 on the display unit 35, and various destinations are displayed on the destination search screen d1. The place search method is displayed as the menu list mt1. An area t1 for displaying a title is formed on the destination search screen d1, and the title “Search by destination” is displayed in the area t1.
[0059]
Further, a return key kb for displaying the previous screen is formed beside the area t1, and selection keys k1 to k4 for selecting a destination search method are formed under the area t1. In k1, the character “search in Japanese syllabary” indicating a destination search method for searching for a destination in Japanese syllabary is displayed on the selection key k2 in “phone” indicating the destination search method for searching for a destination by telephone number. The “Search by number” character is the selection key k3, and the “Search by memory point” character indicates the destination search method for searching the destination at the memory point. The text “Search by address” indicating the location search method is displayed. Note that the destination search screen d1 displays the number of destination search methods that can be displayed on one screen, and the remaining destination search methods are the destination search screen d1. It will be displayed by scrolling.
[0060]
Therefore, for example, when the driver touches the selection key k3 and selects a destination search method using a memory point from among the destination search methods in the menu list mt1, the display processing means selects the selected destination. A search method is set, a memory point screen d2 as shown in FIG. 3 is formed on the display unit 35, and each memory point is displayed as a menu list mt2 on the memory point screen d2. In the memory spot screen d2, an area t2 for displaying a title is formed, and the title of “memory spot list” is displayed in the area t2.
[0061]
Next to the area t2, the return key kb is formed, and selection keys k11 to k14 for selecting a memory point are formed below the area t2. The selection keys k11 to k14 include “Parlor XX”. Characters such as “×”, “Café △△△”, “XX store”, “□□□□ bookstore” are displayed. The memory location screen d2 displays the number of memory locations that can be displayed on one screen, and the remaining memory locations are displayed by scrolling the memory location screen d2. Will come to be.
[0062]
Then, when the driver touches a predetermined selection key among the selection keys k11 to k14 and selects a predetermined memory point from the menu list mt2, the destination setting processing means selects the selected memory point. Set as destination.
[0063]
Since the destination set in this manner is sequentially recorded in the RAM 32, the driver operates the operation unit 34, for example, touches a destination history key formed on a menu screen (not shown), and When the history display is requested, the display processing means forms a destination history screen d3 as shown in FIG. 4 on the display unit 35, and displays the destination history on the destination history screen d3 as a menu list mt3. . On the destination history screen d3, an area t3 for displaying a title is formed, and the title of “destination history” is displayed in the area t3.
[0064]
Next to the area t3, the return key kb is formed, and selection keys k21 to k24 for selecting a destination set in the past under the area t3 are formed, and the selection keys k21 to k24 are formed. In addition, characters such as “XX Bank”, “△△ Hotel”, “Parlor XXX”, “□□ Hospital” are displayed. The destination history screen d3 displays the number of destinations that can be displayed on one screen, and the remaining destinations can be scrolled on the destination history screen d3. Will be displayed.
[0065]
Then, when the driver touches a predetermined selection key among the selection keys k21 to k24 and selects a predetermined destination from the menu list mt3, the destination setting processing means displays the selected destination. Set it as the destination again.
[0066]
By the way, if the selection key k3 can be arbitrarily touched on the destination search screen d1 or the destination history key can be touched arbitrarily on the menu screen, the memory locations and destinations of the menu lists mt2 and mt3 Other people can easily acquire personal information such as history.
[0067]
Therefore, in the present invention, by operating the operation unit 34 in a predetermined method, the predetermined screen is locked, and in order to prevent personal information from being easily acquired by another person, That is, screen formation is regulated.
[0068]
Next, the operation of the screen formation restriction processing by the screen formation restriction processing means (not shown) of the CPU 31 will be described.
[0069]
FIG. 5 is a flowchart for explaining the operation of the screen formation restriction process in the embodiment of the present invention, FIG. 6 is a first view showing a state in which the screen formation is restricted in the embodiment of the present invention, and FIG. It is a 2nd figure which shows the state by which the screen formation in this embodiment was controlled.
[0070]
In the present embodiment, when the return key kb is operated by a predetermined method, it is set as a specific function operation unit having a specific function, that is, a function for restricting screen formation. That is, in the present embodiment, when the return key kb is touched (long pressed) for a set time, for example, 3 seconds or longer, a predetermined screen can be locked and subsequent screen formation can be regulated. ing.
[0071]
For this purpose, first, the restriction condition establishment judgment processing means of the screen formation restriction processing means performs restriction condition establishment judgment processing to determine whether or not a condition for restricting screen formation, that is, whether or not a restriction condition is satisfied. In this case, the restriction condition establishment determination processing means determines whether or not the return key kb is touched on a predetermined screen, for example, the memory point screen d2 of FIG. Determine if touched for more than a second. When the return key kb is touched for 3 seconds or more, the restriction condition establishment determination processing means determines that the restriction condition is satisfied. In this embodiment, it is determined whether or not the return key kb is touched for 3 seconds or more. When the return key kb is touched for 3 seconds or more, the restriction condition establishment determination processing means establishes the restriction condition. However, if the return key kb is touched in a predetermined pattern and the return key kb is touched in a predetermined pattern, the restriction condition establishment determination processing means It can also be determined that
[0072]
When the restriction condition is satisfied, the lock processing means of the screen formation restriction processing means performs a lock process, sets a predetermined screen, in this embodiment, the memory point screen d2 as the restriction screen, and then The formation of the memory spot screen d2 is restricted.
[0073]
For this purpose, the regulation guidance information notification processing means of the screen formation regulation processing means performs regulation guidance information notification processing, and displays the screen immediately before the memory point screen d2, that is, the screen shown in FIG. By forming a destination search screen d1 as shown, setting it as a prior screen and a regulation guidance information notification screen, and graying out the selection key k3 for forming the memory point screen d2 in the destination search screen d1, The driver is informed and notified that the contents of the screen formation restriction, that is, the formation of the memory point screen d2 is restricted.
[0074]
In this case, since the selection key k3 is grayed out, even if another person who is an operator touches the selection key k3, the display processing unit cannot set the destination search method based on the memory point, The memory point screen d2 cannot be formed on the display unit 35. That is, another person cannot select a destination search method based on memory points.
