A vehicle drive including an input coupled to an engine, an output coupled to wheels, an intermediate member between the input and output and coupled to a rotary electric machine, a friction engagement device between the input and intermediate member, and a control device. The control device, when starting the engine with the friction engagement device disengaged, engages the friction engagement device when a rotational speed difference between the input and intermediate member is equal to or less than a predetermined value; raises a rotational speed of the input using the rotary electric machine with the friction engagement device engaged to start the engine; and, when a rotational speed of the engine is equal to or more than a predetermined value, reduces an engagement pressure of the friction engagement device and the friction engagement device is returned to the engaged state when the rotational speed difference reaches a threshold.
A vehicle drive device including an input member drivably coupled to an internal combustion engine, an output member drivably coupled to wheels, an intermediate member provided on a power transfer path connecting between the input member and the output member and drivably coupled to a first rotary electric machine, a friction engagement device capable of releasing drivable connection between the input member and the intermediate member, and a control device, wherein
