摘要： A vehicle drive unit includes a clutch pressure control valve that controls hydraulic pressure for operating the clutch; a clutch control valve that is provided in a first oil passage between the clutch pressure control valve and the clutch, and that controls hydraulic pressure in an engagement state between full engagement and disengagement of the clutch; a second oil passage that bypasses the clutch control valve and that is arranged parallel to the first oil passage; and a shift valve that connects, to an oil passage connected to the clutch, the first oil passage when controlling the engagement state between full engagement and disengagement of the clutch, and the second oil passage when not controlling the engagement state between full engagement and disengagement of the clutch.

摘要： A vehicle drive apparatus for supplying oil pressure to a hydraulic servo at restart of an engine. The vehicle drive apparatus includes an accumulator that accumulates the oil pressure, an electromagnetic switching valve that retains oil pressure of the accumulator when an oil pump is stopped, a switching valve control unit that controls opening and closing of the electromagnetic switching valve, and a restart determining unit that determines whether or not to restart the vehicle drive source from a stopped state. When it is determined by the restart determining unit to restart the vehicle drive source, the switching valve control unit is started so as to supply the oil pressure accumulated in the accumulator to the hydraulic servo. As a result, engine friction engagement elements are quickly engaged to enable starting of a vehicle.
