PROBLEM TO BE SOLVED: To obtain a control device of a power train with a centrifugal pendulum damper which can satisfy both an acceleration requirement by a driver and a vibration reduction requirement by the centrifugal pendulum damper at the transition of an operation state of an engine.SOLUTION: When an engine is in a full-cylinder operation, a connection/disconnection control part controls a connection/disconnection state to a first state, and when the engine is in a reduced-cylinder operation, the connection/disconnection control part controls the connection/disconnection state to a second state which is higher than the first state in a fastening degree. When there is a transition requirement to the full-cylinder operation from the reduced-cylinder operation of the engine, the connection/disconnection control part transits a clutch mechanism to the first state from the second state, and an engine control part transits the engine to the full-cylinder operation from the reduced-cylinder operation, and when there is a transition requirement to the reduced-cylinder operation from the full-cylinder operation of the engine, the connection/disconnection control part transits the clutch mechanism to the second state from the first state, and the engine control part transits the engine to the reduced-cylinder operation from the full-cylinder operation at timing which is retarded by a prescribed period rather than timing at which there is the transition requirement of an operation state to the full-cylinder operation from the reduced-cylinder operation.SELECTED DRAWING: Figure 4
【課題】エンジンの運転状態が移行する際、運転者による車両の加速要求と遠心振子ダンパによる振動低減要求とを共に満たすことが可能な遠心振子ダンパ付きパワートレインの制御装置を実現する。【解決手段】断接制御部は、エンジンの全筒運転時には断接状態を第1状態に制御し、エンジンの減筒運転時には断接状態を第1状態より締結度合いが高い第2状態に制御し、かつ、エンジンの減筒運転から全筒運転への移行要求があったときは、断接制御部は、クラッチ機構を第2状態から第1状態へ移行させ、エンジン制御部は、エンジンを減筒運転から全筒運転へ移行させると共に、エンジンの全筒運転から減筒運転への移行要求があったときは、断接制御部は、クラッチ機構を第1状態から第2状態へ移行させ、エンジン制御部は、運転状態の減筒運転から全筒運転への移行要求があったときよりも所定期間遅い時期に、エンジンを全筒運転から減筒運転へ移行させることを特徴とする。【選択図】図4
