The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.

摘要： A hydraulic control system of an automatic transmission for a vehicle, wherein, in order to achieve an up shift from a specific gear stage to another gear stage in a drive range, there are provided a frictionally engaging device for the normal engagement arranged in series with a one-way clutch and a frictionally engaging device for coasting during engine braking action arranged in parallel to said frictionally engaging device for normal engagement. Hydraulic oil pressure of the frictionally engaging device for normal engagement is controlled in response to a rise or fall in hydraulic oil pressure of the frictionally engaging device for the coasting mode. Thus, combined use of the frictionally engaging device for the coasting mode makes it possible to improve the durability of the frictionally engaging device for normal engagement and decrease the occurrence of shocks generated during shifting operation.

摘要： An hydraulic control system for automatic transmissions includes at least first and second engaging members, a transmission for establishing at least two change gear ratios due to the selective engagement of said first and second engaging members, a first servo-mechanism for controlling the engagement of the first engaging member for shifting to a high speed, and a second servo-mechanism for controlling the engagement of the second engaging member for shifting to a low speed. Shifting to a high speed is established due to engagement of the first engaging member and release of the second engaging member, and shifting to a low speed is established due to release of the first engaging member and engagement of the second engagement member. A shift timing valve controls the communication of the second servo-mechanism with an accumulator for use with the second servo-mechanism, in response to the build-up of a pressure to a given level in the first servo-mechanism.

摘要： A motor vehicle drive system controller is adapted to automatic drive control, the engine and the transmission being among the objects of control. The power output of the motor is controlled so as to maintain either a consistent drivable mode or a consistent undrivable mode as the automatic transmission shifts gears while the vehicle is running under automatic drive control. The consistent drivable mode refers to a state where the output torque of the motor is greater than the sum of the average running resistance and the variation in the running resistance and the consistent undrivable mode refers to a state where the output torque of the motor is smaller than the difference of the average running resistance and the variation in the running resistance. The automatic drive control function is prohibited when the controller detects abnormality in the transmission.
