Abstract

A route searching device for a rechargeable vehicle includes an acquisition unit and a movement plan creation unit. The acquisition unit acquires facility information regarding a use state of a supply facility which includes at least one of vehicle supply facilities which supplies a rechargeable vehicle, and a charging facility which supplies power to a battery of the rechargeable vehicle. The movement plan creation unit creates a movement plan based on map information and the facility information. The movement plan includes a route to a destination, which includes the supply facility to be used, and supply details received by the supply facility on the route.

Claims

1. A route searching device for a rechargeable vehicle, comprising:

an acquisition unit that acquires facility information regarding a use state of a supply facility which includes at least one of a vehicle supply facility which supplies a rechargeable vehicle, and a charging facility which supplies power to a battery of the rechargeable vehicle; and

a movement plan creation unit that creates a movement plan based on map information and the facility information, the movement plan including a route to a destination, which includes the supply facility to be used, and supply details received by the supply facility on the route.

2. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit creates the movement plan which includes, as the supply facility, at least one of:

a next vehicle supply facility on the route or the vehicle supply facility ensuring a rechargeable vehicle which has a state of charge allowing to travel to the next charging facility; and

the charging facility including an available charger which is usable by the rechargeable vehicle upon arrival, as the supply facility used on the route.

3. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit creates the movement plan which includes at least one of:

a transferring vehicle supply facility at which the rechargeable vehicle which has traveled is replaced with another rechargeable vehicle; and

the charging facility as the supply facility used on the route which supplies power to the rechargeable vehicle which has traveled.

4. The route searching device for a rechargeable vehicle according to claim 1, further comprising:

a storage unit that stores the facility information; and

an update unit that updates the facility information in the storage unit based on details of the reserved movement plan, and updates the facility information in the storage unit based on information indicating a state of charge of the rechargeable vehicle acquired by the acquisition unit.

5. The route searching device for a rechargeable vehicle according to claim 1, wherein

the acquisition unit acquires, as the facility information, at least one of:

information indicating a rechargeable vehicle ensured by the vehicle supply facility;

information indicating a state of charge of the rechargeable vehicle;

information indicating a reservation state of the rechargeable vehicle;

information indicating a reservation state of a charger provided in the charging facility;

information used to calculate a fare of the rechargeable vehicle or the charging facility; and

information used to calculate a waiting time in the vehicle supply facility or the charging facility.

6. The route searching device for a rechargeable vehicle according to claim 1, wherein

the acquisition unit acquires positional information indicating a current position of the rechargeable vehicle,

the movement plan creation unit creates the movement plan including a route from the current position to the destination, based on the positional information acquired by the acquisition unit, the map information, and the facility information, and

the route includes the supply facility to be used.

7. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit creates a new movement plan in a case where the acquisition unit acquires new facility information, a case where a predetermined time elapses from when the movement plan was created the previous time, or a case where the route of the movement plan being performed by the traveling rechargeable vehicle is changed.

8. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit creates the movement plan based on the map information and the facility information, the movement plan including:

a moving route between a departure point or the current position, and the first supply facility on the route;

or

a moving route between the destination and the last supply facility on the route.

9. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit creates the movement plan which includes, as the supply details received by the supply facility on the route, at least one of:

information indicating the rechargeable vehicle or the charger used on the route;

a use start time point;

a use end time point;

information indicating a fare of the supply facility on the route; and

information indicating a waiting time of the supply facility used on the route.

10. The route searching device for a rechargeable vehicle according to claim 1, wherein

in a case where a movement plan having a priority in a predetermined priority condition which is higher than a priority order of the reserved movement plan is provided among movement plans of which the details are created after reservation, the movement plan creation unit determines that the movement plan having a high priority is advantageous.

11. The route searching device for a rechargeable vehicle according to claim 1, wherein

the movement plan creation unit selects an optimal movement plan satisfying the priority condition among a plurality of movement plans, based on the set priority condition.

12. A route searching method for a rechargeable vehicle, the method comprising:

an acquisition step of acquiring facility information regarding a use state of a supply facility which includes at least one of a vehicle supply facility which supplies a rechargeable vehicle, and a charging facility which supplies power to a battery of the rechargeable vehicle; and

a movement plan creation step of creating a movement plan based on map information and the facility information, the movement plan including a route to a destination, in which the supply facility to be used is included, and supply details received by the supply facility on the route.

13. A program for causing a computer to execute a process, the process comprising:

an acquisition process of acquiring facility information regarding a use state of a supply facility which includes at least one of a vehicle supply facility which supplies a rechargeable vehicle, and a charging facility which supplies power to a battery of the rechargeable vehicle; and

a movement plan creation process of creating a movement plan based on map information and the facility information, the movement plan including a route to a destination, in which the supply facility to be used is included, and supply details received by the supply facility on the route.
