摘要： A shift control system of an automatic transmission includes a first element which is to be released in a shift operation, a second element which is to be engaged in the shift operation, and a target shift time set section for setting a target time period of the shift operation needed for releasing the first frictional element and engaging the second frictional element. A shift time calculation section is provided for obtaining an actual time period of the shift operation needed for releasing the first frictional element and engaging the second frictional element, and a releasing pressure control section is provided for receiving output of the target shift time set section and the shift time calculation section for controlling a releasing pressure of the first frictional element in the shift operation based on the difference between the target and actual time periods of the shift operation. An engaging pressure control section is used for controlling an engaging pressure of the second frictional element in the shift operation. A shift shock is effectively suppressed by the shift control system.

摘要： An automatic transmission control system, which includes a 2-4 brake having a servo apply fluid chamber and a servo release fluid chamber and a 3-4 clutch having a fluid chamber and causes a 3-2 shift by engaging the 2-4 brake and disengaging the 3-4 clutch, controls engaging pressure for the 3-4 clutch by way of controlling servo apply pressure for the 2-4 brake to disengage the 3-4 brake so as thereby to increase turbine speed during the 3-2 gear shift and, at near the end of the 3-2 gear shift, brings the 2-4 brake into engagement. During control of disengagement of the 3-4 clutch, the pressure difference between servo apply pressure and servo release pressure is changed to become greater at the beginning of the gear shift.
