PROBLEM TO BE SOLVED: To suppress deterioration of an idling vibration regardless of the performance of an elastic mount supporting the engine when controlling idling on an inclined road.SOLUTION: A hybrid vehicle includes an engine, a motor-generator, a left drive wheel and a right drive wheel in a drive system, with the engine supported onto a vehicular body with an elastic mount. In the vehicle, whether a road inclination is a given inclination zone in which a spring function is possibly undermined due to acting force exerted to the elastic mount is determined. When controlling idling on a road whose inclination is the given inclination zone, idling-vibration countermeasure control is executed to raise an engine revolution speed to an engine revolution speed target value that is higher than a normal idling-engine revolution speed and to limit engine torque at an engine torque target value that is lower than normal idling-engine torque, at maximum.SELECTED DRAWING: Figure 9

    【課題】勾配路でのアイドル制御時、エンジンを支持する弾性マウントの性能にかかわらずアイドル振動の悪化を抑制する。【解決手段】駆動系にエンジンとモータジェネレータと左駆動輪及び右駆動輪を有し、エンジンが弾性マウントによって車体に支持されている。このハイブリッド車両において、道路勾配が、弾性マウントに加わる作用力によりバネ機能が損なわれる可能性がある所定勾配領域であるかどうかを判断する。道路勾配が所定勾配領域でのアイドル制御時、エンジン回転数を通常のアイドル時エンジン回転数より高いエンジン回転数目標値に上げ、かつ、エンジントルクを通常のアイドル時エンジントルクよりも低いエンジントルク目標値で上限制限するアイドル振動対策制御を実行する。【選択図】図9
