摘要： A control system for a hydraulic clutch comprises a starting valve and a complete engagement control valve coupled with the starting valve. The starting valve supplies to the clutch a regulated fluid pressure which is elevated in accordance with a revolution speed of an engine when it is in a start fluid pressure regulating state and which is higher than the regulated fluid pressure provided in said start fluid pressure regulating state when it is in said complete engagement fluid pressure regulating state when it is in a complete engagement fluid pressure regulating state. The complete engagement control valve shifts the starting valve from the start fluid pressure regulating state to the complete engagement fluid pressure regulating state when the vehicle speed exceeds a complete engagement vehicle speed.

摘要： The control system comprises a starting valve wherein an engine revolution speed indicative fluid pressure and a start adjustment fluid pressure act on a spool of the valve against each other. The starting valve generates a start pressure to be used as a clutch engagement pressure for a hydraulic clutch. The start adjustment fluid pressure is generated by a start adjustment valve coupled with an electronic control unit. Under the control of the electronic control unit, the start adjustment offsets a variation in the engine revolution fluid pressure when the engine idles with the vehicle at a standstill.

摘要： A hydraulic control system is provided wherein a predetermined delay is provided by controlling the flow of fluid from or to frictional element which contributes to shifting into a neutral state within the transmission. With this delay, the engine can sustain rotational speed necessary for restarting upon resumption of fuel supply even after the manual valve is shifted to the neutral state during running condition of an automotive vehicle where the fuel supply to the engine is interrupted.

摘要： A control device for an automatic transmission comprises an electromagnetic valve that is subject to pulse duty factor control and generates an adjustment pressure variable in a first pattern after a rod of a shift operation mechanism has moved into an overstroke range beyond a maximum reduction ratio position. The adjustment pressure is variable in a second pattern when the rod fails to move into the overstroke range. An adjustment pressure change-over valve is formed integral with the rod and applies the adjustment pressure to a servo actuating pressure regulator valve (i.e., a throttle valve) when the motor vehicle is at a standstill and the engine idles so as to effect a creep torque control. When the motor vehicle starts moving at a speed above a certain vehicle speed, the adjustment pressure change-over valve applies the adjustment pressure to a lock-up control valve, thereby to effect a lock-up control.
