DEVICE AND METHOD OF ADJUSTING RELATIVE POSITION BETWEEN POWER-SUPPLYING COIL AND POWER-RECEIVING COIL
First Claim
1. An adjusting device for adjusting a relative position between a power-supplying coil and a power-receiving coil of an electric vehicle when the electric vehicle has entered and stopped in a stop area for wireless supply of electric power from the power-supplying coil to the power-receiving coil,wherein, the power-supplying coil and a wheel stopper are provided in the stop area, a wheel of the electric vehicle which has entered the stop area touches the wheel stopper, and the power-supplying coil wirelessly supplies power to the power-receiving coil of the electric vehicle stopping as the wheel touches the wheel stopper,the adjusting device comprises:
- a receiver configured to receive, from the electric vehicle, distance data showing a distance between the power-receiving coil and the wheel in a front-back direction of the electric vehicle;
a drive device configured to move the wheel stopper or the power-supplying coil in an approach direction of the electric vehicle to the stop area or in an opposite direction of the approach direction; and
a controller configured to control the drive device, andthe controller makes a distance in the approach direction between the power-supplying coil and the wheel stopper equal to the distance shown by the distance data by controlling the drive device based on the distance data received by the receiver.

Abstract
A power-supplying coil and a wheel stopper are installed in a stop area, and distance data showing a distance in front-back direction between a power-receiving coil and a wheel of an electric vehicle is received by a receiver. Based on the distance data, as a controller controls a drive device, the wheel stopper or the power-supplying coil is moved and a distance in an approach direction between the power-supplying coil and the wheel stopper shown by distance data is made equal to the distance in the front-back direction. Accordingly, in a state in which the wheel of the electric vehicle which has entered the stop area touches the wheel stopper and stops, a position of the power-receiving coil coincides with a position of the power-supplying coil in the approach direction.
