As the display unit 126, a liquid crystal monitor or an organic EL monitor can be adopted. In the present embodiment, the display unit 126 displays a route including a plurality of toll roads having different toll systems according to the shape on the map by being controlled by the first control unit 110, and together with the route, the toll road. Display the price for each. Details of the display contents displayed by the display unit 126 will be described later.

The touch panel 124 is provided so as to be superimposed on the display unit 126, and receives a touch operation from the user with a finger or a pen. The route display device 100 is not limited to the touch panel 124, and may include other input devices such as various buttons, a joystick, and a touch pad.

The positioning unit 136 is provided with a GNSS (Global Navigation Satellite System) receiver, and positions the latitude and longitude which are the current positions of the route display device 100 based on the radio waves received from the artificial satellites constituting the GNSS. To do.

The first control unit 110 is configured as a computer provided with a CPU and a memory, and controls the entire operation of the route display device 100 including the display unit 126. When the computer program recorded in the memory provided in the first control unit 110 is executed by the CPU, the first control unit 110 functions as the bypass processing unit 112. The computer program may be recorded on a non-temporary tangible recording medium such as a memory card. The detour processing unit 112 has a function of accepting the selection of the toll road to be detoured from the toll roads displayed on the display unit 126 and causing the route search server 200 to search for a route that does not pass through the toll road to be detoured.

The route search server 200 includes a second communication unit 202, a map information storage unit 214, a charge information storage unit 216, and a second control unit 204. The second communication unit 202 is a circuit for communicating with the route display device 100 via the Internet 80.

Map data and road network data are stored in the map information storage unit 214. The map data represents the shape of the topography of the whole country. The road network data is data representing a road connection state by link data representing a road and node data representing an intersection, a bend point, and a dead end. Node data contains information that represents latitude and longitude. The link data includes information indicating the nodes constituting the link data, cost information indicating the travel time required to pass the road, and type information indicating whether the road is a toll road or a general road. included.

The toll information storage unit 216 stores toll data representing tolls between interchanges, between junctions, and between interchanges / junctions for each toll road having a different toll system. Toll roads include national highways, general toll roads, urban highways, and toll bridges. Toll roads with different toll systems generally have different business entities. The route search server 200 acquires the latest toll data of each toll road from a server provided in each business entity.

The second control unit 204 includes a CPU and a memory, and controls the entire operation of the route search server 200. When the computer program stored in the memory provided in the second control unit 204 is executed by the CPU, the second control unit 204 functions as the route search unit 206.

More specifically, the route search unit 206 uses the road network data stored in the map information storage unit 214 for the route from the departure point to the destination specified by the route search request received from the route display device 100. Search and generate route information. The route represented by the route information has a shape on the map. That is, the route represented by the route information is not a mere straight line, but has a shape that reflects the connected state of the roads on the map. As the algorithm used for the route search, a well-known Dijkstra method, A-Star algorithm, or the like can be used. The route searched by the route search unit 206 may include a plurality of toll roads having different toll systems. When the searched route includes a toll road, the route search unit 206 refers to the toll data stored in the map information storage unit 214, and the toll for passing through each toll road and the total charge thereof. The charges including these charges are calculated, and the charge information including these charges is generated. The route search unit 206 transmits the route information and the toll information thus generated to the route display device 100.

FIG. 2 is a flowchart of a route display process executed by the route display device 100. This process is executed when a predetermined operation for displaying the route is performed on the route display device 100.

In step S10, the first control unit 110 receives the designation of the departure place and the destination from the user. When the departure place is not specified, the first control unit 110 may use the current position determined by the positioning unit 136 as the departure place.

In step S12, the first control unit 110 transmits a route search request for searching a route from the designated departure point to the destination to the route search server 200. When the route search server 200 receives the route search request from the route display device 100, the route search server 200 generates route information and charge information and transmits the route information to the route display device 100.

In step S14, the first control unit 110 receives the route information, the charge information, and the map data from the route search server 200.

In step S16, the first control unit 110 displays the route represented by the route information on the display unit 126. In the present embodiment, the first control unit 110 displays a map represented by map data on the display unit 126, and displays a route on the map. The displayed route has a shape on the map. That is, the displayed route is not a straight route but has a shape that follows the actual road shape on the map. Further, in step S18, the first control unit 110 displays the charge represented by the charge information together with the route.

FIG. 3 is a diagram showing an example in which a map, a route, and a toll are displayed on the display unit 126. FIG. 3 shows an example in which a route including a plurality of toll roads from the Honda interchange on the Hanshin Expressway to the Marunouchi interchange on the Nagoya Expressway is displayed on the map. Fig. 3 shows (1) Hanshin Expressway section S1 from Honda Interchange to Higashi Osaka Junction, (2) Kinki Expressway section S2 from Higashi Osaka Junction to Monshin Junction, and (3) From Monshin Junction to Katano Minami Interchange. No. 2 Keihan Road Section S3, (4) Meishin Expressway from Katano Minami Interchange to Nagoya West Junction / Shin Meishin Expressway / Higashi Meihan Expressway Section S4, (5) Nagoya Expressway Section from Nagoya West Junction to Marunouchi Interchange The five sections S1 to S5 of S5 are represented. Each of these sections is a toll road with a different toll system. It is preferable that the first control unit 110 controls the display unit 126 to color-code each of these toll roads.

As shown in FIG. 3, the first control unit 110 controls the display unit 126 to display the toll of each toll road near the end point of each toll road. In the present embodiment, the first control unit 110 displays the toll on the display unit 126 by providing a balloon-shaped display area near the end point of each toll road. In the present embodiment, the first control unit 110 controls the display unit 126 so that the entire route and the charge are contained in one screen. Further, in the present embodiment, the first control unit 110 displays the toll of the entire route on the display unit 126 in addition to the individual toll of each toll road.

With reference to FIG. 2, in step S20, the detour processing unit 112 determines whether or not the user has accepted the selection of the toll road to be detoured. The toll road to be detoured is hereinafter referred to as a detour target road. The user selects a detour target road by performing a touch operation using the touch panel 124 on each toll road displayed on the display unit 126 or the toll corresponding to each toll road. That is, the user selects the toll road section that he / she wants to pass on the general road from the currently displayed routes by touch operation. The first control unit 110 controls the display unit 126 to change the color of the toll road selected as the detour target road to a color different from that of the toll road that does not detour, so that the detour target road and the detour are not performed. Display separately from toll roads. When the detour processing unit 112 detects that the detour target road is selected by the user and the detour button B1 displayed on the display unit 126 is operated, the detour processing unit 112 determines that the selection of the detour target road has been accepted. The user can select a plurality of toll roads as detour target roads until the detour button B1 is operated. The display of the detour button B1 may be omitted. In this case, each time the user touch-operates the detour target road or the corresponding toll, the detour processing unit 112 may determine that the selection of the detour target road has been accepted.

When the detour processing unit 112 accepts the selection of the detour target road in step S20, the detour processing unit 112 requests the route search server 200 to search for a route to avoid the detour target road in step S22. The route search unit 206 of the route search server 200 performs the route search again without using the link data and the node data of the detour target road. In addition, the route search unit 206 may search the route by increasing the cost data of the detour target road. Then, the first control unit 110 returns the process to step S14, receives new route information, charge information, and map data from the route search server 200, and executes the processes of steps S16 and S18 described above. A new route and a new charge are displayed on the display unit 126.

In step S20, when the detour processing unit 112 does not accept the selection of the detour target road line and detects the operation of the guidance start button B2 displayed on the display unit 126, the first control unit 110 performs the route display processing. To finish. After the route display process is completed, the first control unit 110 executes a route guidance process that guides the user to the destination based on the route information received from the route search server 200 and the current position determined by the positioning unit 136. To do.

According to the route display device 100 of the present embodiment described above, the toll of each toll road included in the route from the departure point to the destination is displayed together with the route having a shape on the map, so that each of the routes is displayed. You can visually check the relationship between the distance of the toll road and the toll. Therefore, it can be easily determined whether or not the charge for traveling on the route is a charge suitable for traveling on the route, in light of the criteria of each user.

Further, according to the present embodiment, since the toll for each toll road is displayed near the end point of each toll road, it can be easily grasped that the toll is the toll when passing through the toll road.

Further, in the present embodiment, since the route and the toll are displayed on the map, the relationship between the distance of each toll road and the toll can be more easily grasped.

Further, in the present embodiment, since the entire route and the toll are displayed on one screen, the relationship between the distance of each toll road and the toll on the route can be seen at a glance without scrolling or switching screens. Can be grasped.

Further, in the present embodiment, since the route information and the charge information are acquired from the route search server, the processing load of the route display device 100 can be reduced. Further, since the road network data and the toll data are stored in the route search server 200, the route display device 100 can always present the latest route and toll.

Further, in the present embodiment, after displaying the route, it is possible to accept the selection of the toll road to be detoured and search for the route to detour the toll road, so that the user can easily perform each toll after confirming the toll of each toll road. You can specify whether to use the road. As a result, for example, if it is determined that a toll road in the route is a small distance from the total distance, but the ratio of the amount of money to the total amount is large, the toll road is bypassed. Can be judged.
