PROBLEM TO BE SOLVED: To effectively control a power supply amount from a power supply unit with respect to the drive power of a vehicle in response to transmission efficiency between the power supply unit and a power receiving unit.SOLUTION: A power receiving device for a vehicle comprises: a power receiving unit 11 for receiving power from a power supply unit F which is installed outside a vehicle 1; necessary drive power amount calculation means 12 for calculating a necessary drive power amount X according to a drive state of the vehicle 1; and required power supply amount calculation means 13 for calculating a required power supply amount Z to the power receiving unit 11 on the basis of the necessary drive power amount X. When the necessary drive power amount X exceeds a preset first prescribed power amount α, the required power supply amount calculation means 13 performs second control for setting the required power supply amount Z small with respect to the necessary drive power amount X, and when the necessary drive power amount X goes below a second prescribed power amount β which is set to a value smaller than the first prescribed power amount α, setting the required power supply amount Z large with respect to the necessary drive power amount X.SELECTED DRAWING: Figure 1

    【課題】給電ユニットと受電ユニットとの間の伝送効率に対応して、車両の駆動電力に対する給電ユニットからの給電量を効率的に制御する。【解決手段】車両1の外部に設置された給電ユニットFから電力を受電する受電ユニット11と、車両1の運転状態に応じて必要駆動電力量Xを算出する必要駆動電力量算出手段12と、必要駆動電力量Xに基づいて受電ユニット11への要求給電電力量Zを算出する要求給電電力量算出手段13とを備え、要求給電電力量算出手段13は、必要駆動電力量Xが予め設定された第一所定電力量αを超える場合に必要駆動電力量Xに対して要求給電電力量Zを小さく設定し、必要駆動電力量Xが前記第一所定電力量αよりも低い値に設定された第二所定電力量βを下回る場合に必要駆動電力量Xに対して要求給電電力量Zを大きく設定する第二制御を行う。【選択図】図1
