Abstract:
A vehicle drive device that includes an input member that is drivingly connected to a driving force source for wheels; a hydraulic transmission device that includes a transmission input member coaxially disposed with the input member and changes a speed of rotation of the transmission input member and transmits the rotation to a transmission output member; a differential gear device that has an axis different from an axis of the input member and distributes a drive force transmitted from the transmission output member to the wheels; a case that houses at least the transmission device and the differential gear device; an electric oil pump that is driven by a pump rotary electric machine; and a hydraulic control device that controls a hydraulic pressure of oil discharged from the electric oil pump and supplies the oil at least to the transmission device.
