To provide a hybrid vehicle control device that can prevent a situation where a function of a motor cannot be used under an extremely low temperature in the hybrid vehicle that performs zero torque control.SOLUTION: A hybrid vehicle includes: an engine 2; a motor 4 mechanically and directly connected to the engine 2; a high-voltage battery 6 that supplies electric power to the motor 4; an inverter 5 that charges/discharges the electric power between the motor 4 and the high-voltage battery 6; a contactor that is brought into one of an on-state where electric connection is provided between the high-voltage battery 6 and the inverter 5 and an off-state where the electric connection between the high-voltage battery 6 and the inverter 5 is shut down; and a controller 8 that performs zero torque control to control motor torque such that a load applied from the motor 4 to the engine 2 reaches zero during traveling only with a drive source by the engine 2 and that brings the contactor into the off-state when the temperature of the high-voltage battery 6 is lower than a predetermined temperature.SELECTED DRAWING: Figure 1

    【課題】ゼロトルク制御を行なうハイブリッド車両において、極低温状況下でモータの機能が使用できなくなる状況を防止することができるハイブリッド車両の制御装置を提供すること。【解決手段】エンジン2と、エンジン2に機械的に直結されるモータ4と、モータ4に電力を供給する高電圧バッテリ6と、モータ4と高電圧バッテリ6との間で電力の充放電を行なうインバータ5と、高電圧バッテリ6とインバータ5との間を電気的に接続するオン状態と、高電圧バッテリ6とインバータ5との間を電気的に遮断するオフ状態とのいずれか一方の状態をとるコンタクタと、エンジン2のみを駆動源とした走行時にモータ4からエンジン2に与える負荷をゼロにするようにモータトルクを制御するゼロトルク制御を行ない、高電圧バッテリ6の温度が所定温度より低い場合に、コンタクタをオフ状態とする制御部8と、を備える。【選択図】図1
