PROBLEM TO BE SOLVED: To prevent the corotation of an output shaft of an electric motor due to pre-shift and improve fuel economy.SOLUTION: An ECU 300 provided in a DCT 60 of a hybrid electric vehicle executes a pre-shift control to synchronize a rotation speed of a first input shaft IMS or a second input shaft SS corresponding to the other gear position switched from one gear position during traveling at one gear position out of first and second transmission mechanisms with a rotation speed of a counter shaft CS in advance. In a case of traveling while a first clutch C1 is switched to be disengaged to engage a second clutch C2 and a torque of an engine 20 is transmitted from an even-numbered gear position of the second transmission mechanism to the counter shaft CS, the synchronization of the first transmission mechanism under the pre-shift control is cancelled to set the first input shaft IMS into a neutral state. |
