PROBLEM TO BE SOLVED: To lighten a shifting shock to smoothly start and restrain enlargement of the device by providing a second oil pressure generating means capable of supplying oil pressure by which a frictional engagement element for forward or backward becomes directly before engagement, when an engine stops during operation of a vehicle at setting a shift lever on the forward or backward position. SOLUTION: In a hybrid vehicle supplying creep torque to a drive shaft by a second motor generator during stop of a vehicle, oil pressure is supplied by a second oil pressure generating source 9. Hereby a forward clutch 12 or a backward clutch 13 in response to the position of a shift lever 81 is maintained in the condition directly before engagement, and a shifting shock by operation of the shift lever 81 during stop is restrained. While improving operability, the clutch is quickly engaged at restarting the vehicle, and restart of the vehicle can be smoothly performed. At detecting the restarting, translation from running by the second motor generator 4 to ordinary running by driving force of an engine 1 can be smoothly performed, and manufacturing cost can be also reduced by the small size and light weight. |
