Abstract

A movable vehicle power-supplying system of the present disclosure includes power-supplying coils configured to wirelessly supply power to a movable vehicle and provided in a place in which the movable vehicle can stop, a positioning mark provided at a position at predetermined distances from the power-supplying coils, a power-receiving coil provided in the movable vehicle and configured to receive power from the power-supplying coils, a distance identification means provided in the movable vehicle and configured to identify distances between the power-supplying coils and the movable vehicle by detecting the positioning mark, and a control unit configured to assist running of the movable vehicle to the power-supplying coils based on the distances between the power-supplying coils and the movable vehicle identified by the distance identification means.

Claims

1. A movable vehicle power-supplying system for wirelessly supplying power to a movable vehicle, the movable vehicle power-supplying system comprising:

a power-supplying means provided in a place in which the movable vehicle can stop;

a positioning mark provided at a position at a predetermined distance from the power-supplying means;

a power-receiving means provided in the movable vehicle and configured to receive power from the power-supplying means;

a distance identification means provided in the movable vehicle and configured to identify a distance between the power-supplying means and the movable vehicle by detecting the positioning mark; and

a running assist means configured to assist running of the movable vehicle to the power-supplying means based on the distance between the power-supplying means and the movable vehicle identified by the distance identification means.

2. The movable vehicle power-supplying system according to claim 1, wherein the distance identification means captures an image of surroundings of the movable vehicle using a camera and calculates the distance between the power-supplying means and the movable vehicle based on the image of the surroundings.

3. The movable vehicle power-supplying system according to claim 1, in which a plurality of power-supplying means are provided and the positioning mark is provided at a position at predetermined distances from the plurality of power-supplying means, the movable vehicle power-supplying system further comprising:

a power-supplying place notification means configured to notify the movable vehicle of, as a power-supplying place, the power-supplying means at which the movable vehicle does not stop,

wherein the distance identification means calculates a distance to the power-supplying place based on the power-supplying place of the notification provided from the power-supplying place notification means and a detection result of the positioning mark.

4. The movable vehicle power-supplying system according to claim 2, in which a plurality of power-supplying means are provided and the positioning mark is provided at a position at predetermined distances from the plurality of power-supplying means, the movable vehicle power-supplying system further comprising:

a power-supplying place notification means configured to notify the movable vehicle of, as a power-supplying place, the power-supplying means at which the movable vehicle does not stop,

wherein the distance identification means calculates a distance to the power-supplying place based on the power-supplying place of the notification provided from the power-supplying place notification means and a detection result of the positioning mark.

5. The movable vehicle power-supplying system according to claim 1, wherein the running assist means causes the display unit to display a driving assist image indicating a distance between the power-supplying means and the movable vehicle.

6. The movable vehicle power-supplying system according to claim 2, wherein the running assist means causes the display unit to display a driving assist image indicating a distance between the power-supplying means and the movable vehicle.

7. The movable vehicle power-supplying system according to claim 3, wherein the running assist means causes the display unit to display a driving assist image indicating a distance between the power-supplying means and the movable vehicle.

8. The movable vehicle power-supplying system according to claim 4, wherein the running assist means causes the display unit to display a driving assist image indicating a distance between the power-supplying means and the movable vehicle.
