摘要:
A method for responding to a rapid change in engine torque includes monitoring a change in engine torque and determining a rapid change in engine torque when the change in engine torque exceeds a threshold change in engine torque. Subsequent to determining a rapid change in engine torque, an increase in the torque converter slip is provided by reducing the torque converter clutch pressure command by a selected value and thereafter the feedback control is deactivated for a predetermined duration. Subsequent to the predetermined duration, the feedback control is reactivated to decrease the torque converter slip toward a desired torque converter slip value.
