PROBLEM TO BE SOLVED: To perform efficient drive and regeneration using a motor generator provided in auxiliary power transmission means, in a vehicular power transmission apparatus that includes a crank-type transmission unit.SOLUTION: Auxiliary power transmission means S2 that connects an input shaft 12 and an output shaft 13 is disposed parallel to plural transmission units, and a motor-generator MG is disposed in a power transmission path of the aforementioned arrangement, and therefore it is possible to perform and an engine E start and a vehicle start and travel by motor-driving, and power generation by generator-driving. A change ratio of the auxiliary power transmission means S2 is set lower than that of the plural transmission units, and therefore it is possible to prevent a torque lock by a one-way clutch of the transmission unit engaging when drive power is reverse-transmitted toward the engine E through the auxiliary power transmission means S2. Further, the auxiliary power transmission means S2 integrally includes the motor-generator MG, making it possible to improve the workability of assembling to a vehicular power transmission apparatus.SELECTED DRAWING: Figure 6

    【課題】クランク式の伝達ユニットを備える車両用動力伝達装置において、補助動力伝達手段に設けたモータ・ジェネレータを用いて効率的な駆動および回生を行う。【解決手段】入力軸12および出力軸13を接続する補助動力伝達手段S2を複数の伝達ユニットに対して並列に配置し、その動力伝達経路にモータ・ジェネレータMGを配置したので、モータ駆動することによるエンジンEの始動や車両の発進・走行と、ジェネレータ駆動することによる発電とを行うことができる。補助動力伝達手段S2の変速比を複数の伝達ユニットの変速比よりも小さく設定したので、駆動力が補助動力伝達手段S2をエンジンE側に逆伝達するときに、伝達ユニットのワンウェイクラッチが係合してトルクロックの発生を防止することができる。しかも補助動力伝達手段S2はモータ・ジェネレータMGを一体に備えるため、車両用動力伝達装置に対する組付作業性が向上する。【選択図】図6
