To provide an electrically-operated all-wheel drive vehicle that is configured so that front wheels are driven directly by a front electric motor and rear wheels are driven directly by a rear electric motor, which can give a driver a feeling of acceleration which is above vehicle acceleration which is actually generated, when an accelerator pedal is stepped on, in a high-vehicle speed area where output torque of the front electric motor and of the rear electric motor decrease.SOLUTION: An electrically-operated all-wheel drive vehicle 1 comprises: a front motor generator 21 that directly drives front wheels 10FL and 10FR; a rear motor generator 22 that directly drives rear wheels 10RL and 10RR; and an EV-CU 60 that controls driving of the front motor generator 21 and the rear motor generator 22 on the basis of operation amounts of an accelerator and a vehicle speed. In a state where the vehicle speed is above a predetermined speed, the EV-CU 60 changes front and rear distributions of driving force so that weight of the driving force is imposed on the rear wheels, when the operation amounts of the accelerator increase to a predetermined speed or higher.SELECTED DRAWING: Figure 1

    【課題】前輪をフロント電動モータで直接的に駆動し、後輪をリヤ電動モータで直接的に駆動する電動式全輪駆動車であって、フロント電動モータ、リヤ電動モータの出力トルクが低下する高車速域において、アクセルペダルが踏み込まれた場合に、実際に発生する車両加速度以上に、運転者に加速感を与えることが可能な電動式全輪駆動車を提供する。【解決手段】電動式全輪駆動車1は、前輪10FL、10FRを直接的に駆動するフロントモータジェネレータ21と、後輪10RL、10RRを直接的に駆動するリヤモータジェネレータ22と、アクセルの操作量及び車速に基づいて、フロントモータジェネレータ21及びリヤモータジェネレータ22の駆動を制御するEV-CU60とを備える。EV-CU60は、車速が所定速度以上である状態において、アクセルの操作量が所定速度以上で増大された場合に、駆動力の前後配分を後輪偏重側に変化させる。【選択図】 図1
