Beschreibung
Zusammenfassung:	A vehicle drive device includes: a rotating electrical machine; a speed change mechanism including an input member and an output member drivingly connected to wheels, and configured to change a speed ratio between the input member and the output member; a friction engagement device interposed between the rotating electrical machine and the input member and including a friction engagement element configured to connect and disconnect power transmission between the rotating electrical machine and the input member as an engagement pressure is supplied and discharged; and a control device that controls the rotating electrical machine and the friction engagement device. The control device performs learning control when the input member is held stationary and non-rotatable, the learning control being control in which the control device drives the rotating electrical machine while controlling the engagement pressure to an engagement start pressure at which the friction engagement element starts to engage, and learns the engagement start pressure based on a change in driving state of the rotating electrical machine at the time the friction engagement element starts to engage.
