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.

摘要: A vehicle drive unit is provided which includes a hydraulic circuit capable of efficiently supplying a hydraulic pressure from an accumulator to a hydraulic servo while minimizing the capacity of the accumulator. In a hydraulic circuit included in a continuously variable transmission, an accumulator is connected through an electromagnetic switch valve to an oil passage connecting a clutch pressure control valve and a manual valve, a one-way valve for allowing oil to flow only in the direction from the clutch pressure control valve toward the accumulator and the forward clutch is provided in the oil passage. The electromagnetic switch valve switches an oil passage to a communicating state when the oil pump is driven and switches the oil passage to a shut-off state when the oil pump is stopped.
