To provide a parking assisting device of an electric vehicle which can smoothly perform coil alignment for a short time.SOLUTION: A parking assisting device of an electric vehicle, which has a travelling battery for accumulating travelling power and a power receiving coil capable of receiving power from a power transmitting coil of a ground facility in a non-contact manner and is mounted on an electric vehicle for charging the travelling battery by the power received by the power receiving coil, includes a first detection part capable of detecting a distance between the power transmitting coil and the first detection part in a state in which the electric vehicle and the power transmitting coil are separated from one another in a horizontal direction, a second detection part for detecting excitation for aligning the power transmitting coil through the power receiving coil, and a parking assist control part capable of controlling travelling of the electric vehicle. The parking assist control part performs speed control (T1 and T2) of the electric vehicle based on detection of a first detection part and speed control (T3 and T4) of the electric vehicle based on detection of a second detection part at the time of parking assisting of aligning the position of the power receiving coil with the power transmitting coil.SELECTED DRAWING: Figure 5
【課題】スムースで短時間にコイルの位置合せを行うことのできる電動車両の駐車支援装置を提供する。【解決手段】走行用の電力を蓄積する走行用バッテリと、地上設備の送電コイルから非接触で受電可能な受電コイルとを有し、受電コイルが受けた電力で走行用バッテリを充電する電動車両に搭載される電動車両の駐車支援装置であって、電動車両と送電コイルとが水平方向に離れている状態で送電コイルまでの距離を検出可能な第1検出部と、送電コイルの位置合せ用の励磁を受電コイルを介して検出する第2検出部と、電動車両の走行の制御が可能な駐車支援制御部とを備える。そして、駐車支援制御部は、受電コイルの位置を送電コイルに合わせる駐車支援の際に、第1検出部の検出に基づく電動車両の速度制御(T1、T2)と、第2検出部の検出に基づく電動車両の速度制御(T3、T4)とを行う【選択図】図5
