Abstract
【解決手段】 係合装置(切換クラッチC0或いは切換ブレーキB0)を備えることで、変速機構10が無段変速状態と有段変速状態とに切り換えられて、電気的に変速比が変更させられる変速機の燃費改善効果と機械的に動力を伝達する歯車式伝動装置の高い伝達効率との両長所を兼ね備えた駆動装置が得られる。また、上記変速機構10において、エンジン8が停止させられる時には、切換制御手段50により切換クラッチC0或いは切換ブレーキB0が解放されるので、エンジン回転速度NEが伝達部材18の回転速度に拘束されない自由回転状態とされ、第1電動機M1を用いてエンジン回転速度NEが共振の発生が抑制されるように回転制御させられてエンジン停止性が向上する。
