Abstract: A hydraulic control system includes a linear solenoid valve, an ON-OFF solenoid valve and a hydraulically-operated frictional engagement device. A first hydraulic pressure is regulated by the linear solenoid valve within a predetermined pressure-regulation control range, and is supplied to the frictional engagement device. In a state in which the frictional engagement device is placed in a predetermined engaged state based on the first hydraulic pressure, a second hydraulic pressure, which is higher than the pressure-regulation control range, is supplied from the ON-OFF solenoid valve to the frictional engagement device, such that the frictional engagement device is placed in a fully engaged state with a high engaging torque based on the second hydraulic pressure.

Abstract: In a converter circuit of an electric power conversion device, an adjustment portion divides a voltage of a battery input to a semiconductor module, by a first capacity element and a second capacity element that are connected in series to each other. Then, a middle point between the first capacity element and the second capacity element is connected to a cooler to fix a potential thereof. The electric power conversion device can ensure that a waveform of a surge voltage that is generated on a creepage surface between a lead frame terminal and the cooler has a negative voltage range (a range where an offset voltage is applied).

Abstract: 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.
