Vehicle And Contactless Power Feeding System
First Claim
1. A vehicle capable of receiving power from a power transmission device in a contactless manner, comprising:
- a power reception unit that receives power from a power transmission unit included in the power transmission device in a contactless manner;
a moving device configured to move the power reception unit from a standby position in a direction toward the power transmission unit; and
a control device configured to perform first detection operation of detecting a position of the power transmission unit when the power reception unit is located in the standby position, and second detection operation of detecting a position of the power transmission unit when the power reception unit is located in a position closer to the power transmission unit than in the standby position,the control device causing the power transmission device to start power transmission, when it is detected that the power transmission unit is located within a first predetermined range in the first detection operation and when it is detected that the power transmission unit is located within a second predetermined range in the second detection operation.

Abstract
A contactless power feeding system is capable of supplying power from a power transmission unit to a power reception unit in a contactless manner. The contactless power feeding system includes a raising and lowering mechanism that moves the power reception unit from a standby position toward the power transmission unit, and a vehicle ECU. The vehicle ECU performs first detection operation of detecting a position of the power transmission unit when the power reception unit is located in the standby position, and second detection operation of detecting a position of the power transmission unit when the power reception unit is located in a power reception position. The vehicle ECU causes the power transmission unit to start power transmission when it is detected that the power transmission unit is located within a predetermined range in both of the first and second detection operations.

10. A contactless power feeding system that supplies power from a power transmission unit to a power reception unit in a contactless manner, comprising:
-
a moving device configured to move at least one of the power transmission unit and the power reception unit from a standby position in a direction in which the power transmission unit and the power reception unit are brought closer to each other; and a control device configured to perform first detection operation of detecting positional relation between the power transmission unit and the power reception unit when the power transmission unit and the power reception unit are located in the standby positions, and second detection operation of detecting the positional relation when a distance between the power transmission unit and the power reception unit is shorter than the distance with the power transmission unit and the power reception unit being in the standby positions, the control device causing the power transmission unit to start power transmission, when it is detected that the positional relation satisfies a first predetermined condition in the first detection operation and when it is detected that the positional relation satisfies a second predetermined condition in the second detection operation.
