Abstract

A vehicle power-supplying system that wirelessly supply power to a vehicle includes a power-supplying coil installed at a location at which the vehicle can be stopped, first and second positioning posts whose positional relationship with the power-supplying coil is fixed, a position-identifying means installed in the vehicle and configured to identify a positional relationship of the power-supplying coil with the vehicle by detecting the first and second positioning posts, and a traveling support means configured to support traveling of the vehicle to the power-supplying coil based on the positional relationship with the power-supplying coil identified by the position-identifying means.

Claims

1. A vehicle power-supplying system that wirelessly supply power to a vehicle, the vehicle power-supplying system comprising:

a power-supplying means installed at a location at which the vehicle is able to stop;

at least one positioning mark whose positional relationship with the power-supplying means is fixed;

a position-identifying means installed in the vehicle and configured to identify a positional relationship of the power-supplying means with the vehicle by detecting the positioning mark; and

a traveling support means configured to support traveling of the vehicle to the power-supplying means based on the positional relationship of the power-supplying means identified by the position-identifying means.

2. The vehicle power-supplying system according to claim 1, wherein

the location at which the vehicle is able to stop is a rectangular location, and

one of the positioning marks is installed behind an vehicle entrance set to one of a pair of short sides of the rectangular location and one of the positioning marks is installed at one of a pair of long sides of the rectangular location.

3. The vehicle power-supplying system according to claim 1, wherein the position-identifying means identifies, as the positional relationship of the power-supplying means, distance data in two perpendicular axial directions including a widthwise direction and a lengthwise direction in plan view of the vehicle.

4. The vehicle power-supplying system according to claim 2, wherein the position-identifying means identifies, as the positional relationship of the power-supplying means, distance data in two perpendicular axial directions including the widthwise direction and the lengthwise direction in plan view of the vehicle.

5. The vehicle power-supplying system according to claim 1, wherein the position-identifying means photographs a peripheral image of the vehicle using a camera, and identifies the positional relationship of the power-supplying means based on the peripheral image.

6. The vehicle power-supplying system according to claim 2, wherein the position-identifying means photographs a peripheral image of the vehicle using a camera, and identifies the positional relationship of the power-supplying means based on the peripheral image.

7. The vehicle power-supplying system according to claim 3, wherein the position-identifying means photographs a peripheral image of the vehicle using a camera, and identifies the positional relationship of the power-supplying means based on the peripheral image.

8. The vehicle power-supplying system according to claim 1, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

9. The vehicle power-supplying system according to claim 2, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

10. The vehicle power-supplying system according to claim 3, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

11. The vehicle power-supplying system according to claim 4, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

12. The vehicle power-supplying system according to claim 5, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

13. The vehicle power-supplying system according to claim 6, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.

14. The vehicle power-supplying system according to claim 7, wherein the traveling support means displays a driving support image showing the positional relationship of the power-supplying means on a display unit.
