A vehicle comprises: an alternating current (AC) motor generator (MG) connected to a driving wheel; a battery; an inverter converting direct current (DC) from the battery into AC and supplying the AC to the MG; and a vehicle electronic control unit (ECU) controlling the inverter. The vehicle ECU performs a zero torque control to drive the inverter so that output torque from the MG is zero when the battery is prohibited from being charged while the MG is rotated by power from the driving wheel.

차량은, 구동륜에 접속된 교류의 MG(모터 제너레이터)와, 전지와, 전지로부터의 직류를 교류로 변환하여 MG에 공급하는 인버터와, 인버터를 제어하는 차량 ECU를 구비한다. 차량 ECU는, MG가 구동륜으로부터의 동력으로 회전하고 있는 상태에서 전지의 충전이 금지되어 있는 경우, MG의 출력 토크가 제로가 되도록 인버터를 구동하는 제로 토크 제어를 실행한다.
