PROBLEM TO BE SOLVED: To provide a control unit that controls engagement devices, which form a gear train other than a one-way gear train, into a slid and engaged state, controls engagement of a one-way engagement device even when a rotating speed of a rotary electric machine is raised, and shifts gear trains as readily as possible when a request for shifting the gear trains is issued.SOLUTION: A transmission includes a one-way gear train formed with engagement of first and one-way engagement devices, and a low gear train formed with engagement of first and second engagement devices. When a request for starting an internal combustion engine is issued, a control unit controls the second engagement device into a slid and engaged state, and decides on the possibility that the one-way engagement device is engaged when a rotating speed of a rotary electric machine is augmented. If the possibility is low, the second engagement device is controlled into the slid and engaged state. If the possibility is high, the first engagement device is controlled into the slid and engaged state. |
