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 supplies power to a vehicle including a power-receiving coil, the vehicle power-supplying system comprising:

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

at least two positioning marks with unique patterns 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 positioning mark; and

a control device configured to support positioning the vehicle to the power-supplying coil based on the positional relationship of the power-supplying coil identified by the position-identifying means,

wherein

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

a first position mark of the at least two positioning marks is installed in the vicinity of the other short side of a vehicle entrance set to one of a pair of short sides of the rectangular location and a second position mark of the at least two positioning marks is installed at one of a pair of long sides of the rectangular location,

the position-identifying means includes;

a first camera or a first laser sensor installed at a rear or front section of the vehicle; and

a second camera or a second laser sensor installed at a left and/or right section of the vehicle,

the control device includes a central processing unit (CPU) and controls a touch panel and a speaker to support the positioning of the vehicle to the power-supplying coil by images and sounds, and

when the power-supplying coil and the power-receiving coil face each other, the first camera or the first laser sensor, and the second camera or the second laser sensor detect the first and second positioning marks.

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

3. 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 coil based on the peripheral image.

4. The vehicle power-supplying system according to claim 3, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

5. The vehicle power-supplying system according to claim 2, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

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

7. The vehicle power-supplying system according to claim 6, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

8. 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 coil based on the peripheral image.

9. The vehicle power-supplying system according to claim 8, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

10. 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 coil based on the peripheral image.

11. The vehicle power-supplying system according to claim 10, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

12. The vehicle power-supplying system according to claim 1, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

13. The vehicle power-supplying system according to claim 1, wherein the control device displays a driving support image showing the positional relationship of the power-supplying coil on a display unit.

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

the second camera or the second laser sensor is installed at either one of the left or right section of the vehicle.

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

the position-identifying means calculates a relative position of the power-supplying coil with the vehicle based on a first peripheral image input from the first camera, a second peripheral image input from the second camera and a pre-stored relative position table.

16. A vehicle including a power-receiving coil that wirelessly receives power from a power-supplying coil, the vehicle comprising:

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 two positioning marks with unique patterns; and

a control device configured to support traveling of the vehicle to the power-supplying coil based on the positional relationship of the power-supplying coil identified by the position-identifying means, wherein

the position-identifying means includes;

a first camera or a first laser sensor installed at a rear or front section of the vehicle; and

a second camera or a second laser sensor installed at a left or right section of the vehicle,

the control device includes a central processing unit (CPU) and controls a touch panel and a speaker to support the positioning of the vehicle to the power-supplying coil by images and sounds, and

when the power-supplying coil and the power-receiving coil face each other, the first camera or the first laser sensor, and the second camera or the second laser sensor detect the two positioning marks.
