DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road pricing system for charging a vehicle entering a specific area, and more particularly, for charging a route in a route guidance device mounted on the vehicle. The present invention relates to a detour route guidance device for guiding a detour route without inadvertently passing through an area.

[0002]

2. Description of the Related Art As a device for guiding a route from a starting point to a destination, a car navigation device is used.

[0003]

According to the above prior art, a car capable of calculating a shortest distance to a destination or estimating a shortest required time to provide a route guide according to a purpose of use of a user. Navigation devices are used.

[0004] In order to restrict vehicles entering a specific area or the like, road pricing for charging the entering vehicles has been studied. In the road pricing system currently under study, a similar system to an automatic toll collection system in which onboard equipment mounted on a vehicle and on-road equipment installed on the road perform wireless communication is being studied. If you enter the charging area for road pricing, you are automatically charged. However, in the conventional car navigation device, route guidance is performed based on the shortest distance to the destination and the estimated shortest required time, and thus the guided route may pass through the charging target area for road pricing. At this time, even if the user does not want to pass through the chargeable area for road pricing, the user may pass through the chargeable area without being conscious of the user's intention.

[0005] It is an object of the present invention to provide a detour route guidance device for guiding a route bypassing a chargeable area when a user does not want to pass through a chargeable area for road pricing.

[0006]

According to the first aspect of the present invention, the detour route calculating means stores the departure point set by the departure point setting means and the destination set by the destination setting means in map information. Reference is made by means. Further, when calculating the guide route from the departure point to the destination, the detour route calculating means refers to the charging area stored in the charging area storage means and does not select a route that passes through the charging area so that the detour route is not selected. Since the calculation is performed, it is feasible to provide guidance on a route that bypasses the charging area.

According to the second aspect of the present invention, the detour route calculating means refers to the departure point set by the departure point setting means and the destination set by the destination setting means from the map information storage means. Further, when the detour route calculating means is instructed to detour the charging area by the charging area detour instructing means, when calculating the guide route from the starting point to the destination, the detour route calculating means is stored in the charging area storage means. Since the detour route is calculated by referring to the charging area and not selecting a path passing through the charging area, it is possible to realize guidance of a route that bypasses the charging area. Conversely,
If it is not instructed to detour the charging area by the charging area detour instructing means, the shortest distance from the departure point to the destination and the shortest route calculation are performed without detouring the charging area, and It becomes feasible to provide route guidance as needed.

[0008] According to the third aspect of the present invention, the detour route calculating means refers to the departure point set by the departure point setting means and the destination set by the destination setting means from the map information storage means. Further, the detour route calculation means can obtain a part or all of the latest information on the chargeable area from the outside by the communication means. When calculating the guidance route from the departure point to the destination, the detour route is calculated by referring to the latest information on the charging area obtained by the communication means and not selecting the route passing through the charging area. Even in the case of charging areas that change depending on the day of the week or the day of the week, or when the charging area and charging amount change depending on how crowded the charging area is, it is possible to reliably provide guidance on a route that bypasses the charging area Will be possible.
