    摘要： A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.

    摘要： A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space.
