PROBLEM TO BE SOLVED: To more properly position a power transmitting coil and a power receiving coil.SOLUTION: A solenoid coil 37a for position detection is disposed in such a manner that a winding axis comes in a longitudinal direction of a vehicle and becomes a center location of a power receiving coil 34.When the vehicle moves backwards and the power receiving coil 34 approaches a power transmitting coil 134, an induction voltage Vi of the solenoid coil 37a for position detection induced by weak power that is transmitted by the power transmitting coil 134 is detected. When the induction voltage Vi reaches a maximal value, a distance equal to a radius of the power transmitting coil 134 or a distance a littler shorter than the radius is output as a movement recommendation distance. By moving the vehicle while using such a movement recommendation distance, the power transmitting coil 134 and the power receiving coil 34 can be positioned more properly.SELECTED DRAWING: Figure 3

    【課題】送電用コイルと受電用コイルの位置決めをより適正に行なう。【解決手段】位置検出用ソレノイドコイル37aを巻回軸が車両前後方向となるように且つ受電用コイル34の中心位置となるように配置する。車両が後進して受電用コイル34が送電用コイル134に近づいたときに、送電用コイル134が送電している微弱電力によって誘起する位置検出用ソレノイドコイル37aの誘起電圧Viを検出する。そして、誘起電圧Viが極大値に至ったときに送電用コイル134の半径に等しい距離やそれより若干短い距離を移動推奨距離として出力する。こうした移動推奨距離を用いて車両を移動させることにより、送電用コイル134と受電用コイル34との位置決めをより適正に行なうことができる。【選択図】図3
