发明名称 AUTOMATIC TRANSMISSION AND HYDRAULIC CONTROL METHOD THEREFOR
摘要 A command hydraulic pressure learning control unit includes an output-side torque time rate of change calculation unit for calculating a time rate of change of a torque at an output side of an automatic transmission, and a correction unit for correcting a command hydraulic pressure when transmission of a drive force of a friction element to be engaged is started at the time of a next shift based on a difference between the calculated time rate of change of the output-side torque and a target value.
