To suppress overheat of an inverter, while suppressing charging of a battery by regenerative electric power, when charging of the battery is prohibited in the state where a rotary electrical machinery is rotated by power from a driving wheel.SOLUTION: A vehicle includes an alternating current MG (motor generator) connected to a driving wheel, a battery, an inverter for converting a direct current from the battery to an alternating current and supplying it to the MG, and a vehicle ECU for controlling the inverter. The vehicle ECU executes null-torque control for driving the inverter so that output torque of the MG becomes null, when charging of the battery is prohibited in the state where the MG is rotated by power from the driving wheel.SELECTED DRAWING: Figure 6

【課題】回転電機が駆動輪からの動力で回転している状態で電池の充電が禁止されている場合に、回生電力で電池が充電されることを抑制しつつ、インバータの過熱を抑制する。【解決手段】車両は、駆動輪に接続された交流のＭＧ（モータジェネレータ）と、電池と、電池からの直流を交流に変換してＭＧに供給するインバータと、インバータを制御する車両ＥＣＵとを備える。車両ＥＣＵは、ＭＧが駆動輪からの動力で回転している状態で電池の充電が禁止されている場合、ＭＧの出力トルクがゼロとなるようにインバータを駆動するゼロトルク制御を実行する。【選択図】図６
