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.

A hydraulic pressure control circuit of a torque converter includes a torque converter control valve for controlling a line pressure supplied from a line regulator valve stably controlling a hydraulic pressure supplied from a hydraulic pump to be directly supplied to a fluid chamber inside a torque converter case as an operation hydraulic pressure, a reducing valve for stably controlling the hydraulic pressure, a torque converter control solenoid valve for controlling the hydraulic pressure supplied from the line regulator valve to be supplied to an engage hydraulic chamber of the lock-up clutch, and a switch valve for supplying the hydraulic pressure supplied from the reducing valve to a releasing hydraulic chamber of the lock-up clutch or exhausting the hydraulic pressure of the releasing hydraulic chamber of the lock-up clutch while being controlled by a control pressure of the torque converter control solenoid valve.

Actuator arrangement for a drive train, which has at least one friction clutch for transmitting drive torque and has a transmission. The friction clutch can be actuated by means of a hydraulic clutch cylinder, which is connected directly to a pump port of a pump driven by an electric motor in order to actuate the friction clutch, such that the friction clutch can be actuated by varying the speed of the pump. The actuator arrangement has a parking lock actuator device for actuating a parking lock arrangement of the drive train. The parking lock actuator device has at least one hydraulic parking lock cylinder, which can be connected to the pump, such that the parking lock arrangement can be actuated by varying at least one of the direction of rotation or the speed of the pump.
