摘要： An automatic transmission mechanism having multiple ratio gearing and clutch and brake elements operated by fluid pressure operated servos for changing speed ratio in the transmission and a controller for actuating and releasing the clutches and brakes in response to operating demands determined by sensed variables such as vehicle speed, engine torque, manual valve position, transmission turbine speed, and engine temperature, and means for achieving improved control of a synchronous downshift event by electronically regulating the exhaust pressure from an off-going friction element of the clutch and brake structure, thus controlling the torque-carrying capacity of that off-going element during the downshift interval.

摘要： A transmission includes a plurality of friction units to effect shifting between gear ratios, one of which includes driving and driven elements which may operate with a speed differential at the time of shifting between gear ratios. A first or line pressure is generated which is variable in a first pattern corresponding approximately to the pattern of torque output of the vehicle engine. This pressure is supplied to a friction unit other than the one friction unit to operate such other friction unit. A second pressure is generated which is variable in a second pattern corresponding approximately to a combination of the pattern of the engine torque output and the pattern of differential speed between the driving and driven elements of said one friction unit at the time of engagement of the elements. The second pressure is directed to said one friction unit to operate such one friction unit.

摘要： In a hydraulic control system of an automatic power transmission for an automotive vehicle, the frictional units in the transmission mechanism are operated by a line pressure which is regulated to vary with torque output of the engine and which is reduced to be variable with energy output of the engine when one frictional unit is to be actuated to make an upshift between predetermined forward drive gear ratios or reduced to a substantially constant when another frictional unit is to be actuated to make a downshift between other predetermined forward drive gear ratios for thereby reducing or eliminating shocks which would otherwise be created during the upshift or downshift.
