摘要： A hydraulic control system for an automatic transmission of automotive vehicles is provided. The hydraulic control system includes a pressure source, a plurality of solenoid valves, and a plurality of directional control valves. Each solenoid valve selectively supplies and release hydraulic pressure to and from one of frictional element of a power train of the automatic transmission according to a given schedule of transmission operation for establishing a given gear ratio. The directional control valves are interposed between the frictional elements of the power train and the solenoid valves, respectively. Each of the directional control valves is responsive to input of the hydraulic pressure supplied from the pressure source through a preselected hydraulic line to assume first and second valve positions, the first valve position being to allow the hydraulic pressure to be directed to one of the frictional elements, the second valve position being to release the hydraulic pressure acting on one of the frictional element. Additionally, the hydraulic pressure to activate the frictional elements is reduced in pressure level temporarily upon supply thereto for absorbing mechanical shock caused by engagement of the frictional elements.

摘要： A hydraulic control method is applied to a continuously variable speed change gear mechanism including a pulley having a fixed pulley member fixed to a rotary shaft and a movable pulley member movable by oil pressure toward and away from the fixed pulley member so that a groove width between the fixed and movable pulley members is decreased or increased to thereby reduce or increase the effective rotational radius of a belt extending between the pulley members and thus change a change gear ratio and control the gear change. In this method, first to third three-way electromagnetic pressure control valves control the oil pressure and an electronic control unit (ECU) controls the electromagnetic valves, and driving frequencies of the valves are switched by the ECU in accord with the oil temperature and/or vehicle speed so that the hydraulic clutch is smoothly and effectively operated, the lifetime of the electromagnetic valves is extended, and vibration of the vehicle body due to pressure fluctuation in the hydraulic circuit is prevented.
