Abstract

An object of the present invention is to provide a navigation apparatus, a vehicle information display apparatus, and a vehicle information display system, that enables a travelable range to be recognized even while a user is not riding on an electric vehicle.

A vehicle information display system according to the present invention includes a navigation apparatus and a vehicle information display apparatus. The navigation apparatus includes: a storage section mounted on an electric vehicle, for storing map information and a destination; an own vehicle position information acquisition section for obtaining own vehicle position information; a remaining power amount acquisition section for obtaining a remaining power amount; a travel cost calculation section for calculating a power cost based on the map information, the destination, and the own vehicle position information; a travelable range calculation section for calculating a travelable range based on the power cost and the remaining power amount; and a communication section for transmitting vehicle information including the travelable range to the outside. The vehicle information display apparatus includes: a communication section installed outside the electric vehicle, for receiving the vehicle information; and a control section for outputting the vehicle information.

Claims

1. An apparatus comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, results in performance of steps comprising;

acquiring a remaining power amount of a battery of an electric vehicle;

calculating a travelable range based on said remaining power amount; and

outputting vehicle information that includes said travelable range to a display device located outside said electric vehicle,

wherein said vehicle information is displayed so as to be visible to a vehicle user not riding on said electric vehicle, and

wherein a travel cost calculation condition is inputted by the vehicle user not riding on said electric vehicle, and said travel cost calculation condition is used when said travelable range is calculated.

2. The apparatus according to claim 1, wherein said apparatus is located outside said electric vehicle.

3. The apparatus according to claim 2, wherein the steps further comprise:

receiving a charge start signal; and

outputting the charge start instruction to outside of said apparatus when the charge start signal is received.

4. The apparatus according to claim 3, wherein the steps further comprise:

receiving a charge completion signal; and

notifying completion of charging when said charge completion signal is received.

9. The apparatus according to claim 1, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

10. The apparatus according to claim 2, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

11. The apparatus according to claim 3, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

12. The apparatus according to claim 4, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

5. An apparatus located outside an electric vehicle, comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, results in performance of steps comprising;

acquiring vehicle information that includes travelable range calculated based on a remaining power amount of a battery of said electric vehicle and a travel cost calculation condition; and

outputting said vehicle information to a display device located outside said electric vehicle,

wherein said vehicle information is displayed so as to be visible to a vehicle user not riding on said electric vehicle; and

wherein said travel cost calculation condition is inputted by the vehicle user not riding on said electric vehicle.

6. The apparatus according to claim 5, wherein the steps further comprise:

receiving a charge start signal; and

outputting the charge start instruction to outside of said apparatus when the charge start signal is received.

7. The apparatus according to claim 6, wherein the steps further comprise:

receiving a charge completion signal; and

notifying completion of charging when said charge completion signal is received.

13. The apparatus according to claim 5, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

14. The apparatus according to claim 6, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

15. The apparatus according to claim 7, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

8. An apparatus mounted on an electric vehicle, comprising:

a processor to execute a program; and

a memory to store the program which, when executed by the processor, results in performance of steps comprising;

acquiring a remaining power amount of a battery of an electric vehicle;

outputting vehicle information that includes said remaining power amount to the outside of said electric vehicle,

wherein a travelable range is calculated based on said remaining power amount and a travel cost calculation condition; and

wherein said travelable range is displayed so as to be visible to a vehicle user not riding on said electric vehicle, and

wherein said travel cost calculation condition is inputted by the vehicle user on the outside of said electric vehicle.

16. The apparatus according to claim 8, wherein said travel cost calculation condition is ON/OFF of an air conditioner.

17. A vehicle information display control method comprising:

acquiring a remaining power amount of a battery of an electric vehicle;

calculating a travelable range based on said remaining power amount; and

outputting vehicle information that includes said travelable range to a display device located outside said electric vehicle,

wherein said vehicle information is displayed so as to be visible to a vehicle user not riding on said electric vehicle, and

wherein a travel cost calculation condition is inputted by the vehicle user not riding on said electric vehicle, and said travel cost calculation condition is used when said travelable range is calculated.

18. A vehicle information display control method comprising:

acquiring vehicle information that includes travelable range calculated based on a remaining power amount of a battery of said electric vehicle and a travel cost calculation condition; and

outputting said vehicle information to a display device located outside said electric vehicle,

wherein said vehicle information is displayed so as to be visible to a vehicle user not riding on said electric vehicle; and

wherein said travel cost calculation condition is inputted by the vehicle user not riding on said electric vehicle.

19. A vehicle information display control method comprising:

acquiring a remaining power amount of a battery of an electric vehicle;

outputting vehicle information that includes said remaining power amount to the outside of said electric vehicle,

wherein a travelable range is calculated based on said remaining power amount and a travel cost calculation condition; and

wherein said travelable range is displayed so as to be visible to a vehicle user not riding on said electric vehicle, and

wherein said travel cost calculation condition is inputted by the vehicle user on the outside of said electric vehicle.
