摘要:
Mutual interference between a hydraulic pressure of a first engagement device and a hydraulic pressure of a second engagement device is suppressed even in the case where operation of the first engagement device and operation of the second engagement device coincide with each other. A vehicle drive device includes a first engagement device that selectively couples a rotary electric machine to an internal combustion engine, and a fluid coupling. The first engagement device includes a first oil chamber that is formed to apply a back pressure to a first piston. The fluid coupling includes a second oil chamber configured to control an engagement state of a second engagement device. The vehicle drive device includes a first control valve that controls a first oil chamber hydraulic pressure, and a second control valve that controls a second oil chamber hydraulic pressure independently of the first oil chamber hydraulic pressure.
