发明名称 CONTROL METHOD AT SHIFT TRANSITION
摘要 PURPOSE:To reduce shift shock even if the condition is changed by controlling the line pressure so as to let the drive shaft torque detected value follow to a target torque signal, and further giving a signal to an engine control part so as to control the engine torque to reduce. CONSTITUTION:A target torque generation part 9 which generates a drive torque target value during shifting in a transmission is provided, a drive torque computation part 10 which computes drive torque is provided, the deviation obtained by comparing both outputs with each other is given to a line pressure command part 11, and the clutch pressure of the transmission 3 is controlled through a line pressure control part so as to let the drive torque dur-ing shifting follow to a target torque and adjust the clutch transmission torque. Simultaneously with the line pressure control, when the deviation becomes a negative value over a prescribed value, a torque reduction command part 21 outputs a torque reduction signal to an engine control device 7, and controls the engine torque to reduce. Hereby, even if the condition is changed, the shift shock can be reduced.
