PROBLEM TO BE SOLVED: To start a vehicle with only a motor generator, and also, to start the rotation of an engine in stop, and suppress and prevent the change in drive power at that time. SOLUTION: The first clutch 36 is interposed between a pinion carrier C rotated by a motor/a generator 2 at start of a vehicle and an engine, and a second clutch 37 is interposed between the engine 1 and a ring gear R, and to start the rotation of the engine 1 in idling stop, only the first clutch 36 is coupled to reduce the rotational torque of the ring gear 4 thereby suppressing the reduction of drive force, and after the engine 1 starts its explosive rotation, the second clutch 37 is coupled, and the torque of the engine 1 is distributed to the rotation of the ring gear R to suppress the sharp increase in drive force. |
