Hydraulic control system for automatic transmissions to improve shift quality |
摘要 |
A hydraulic control system for an automatic transmission includes a pressure regulator to regulate hydraulic pressure produced by an oil pump; a manual and automatic shift controller to form shift modes; and a hydraulic pressure controller to regulate shift quality and responsiveness such that shift modes are smoothly formed during shifting. A damper clutch controller operates a damper clutch of a torque converter. A hydraulic pressure distributor supplies and distributes appropriate amounts of hydraulic pressure to friction members that operate as input and reaction members in each shift stage.
