Abstract
A method and control module for controlling a transmission of a vehicle includes a clutch torque load predictor module generating a predicted clutch torque load signal for the shift command and a minimum clutch pressure module generating a minimum clutch pressure signal corresponding to a minimum clutch pressure. The control module includes a pressure command module generating a commanded clutch pressure signal for the predicted clutch torque load signal based on the minimum clutch pressure signal and commanding operation of a clutch with a commanded clutch pressure signal. The control module also includes a transmission control module generating the shift command after the clutch torque load predictor module generates the predicted clutch signal, the minimum clutch pressure module generates the minimum clutch pressure signal and the pressure command module generates the commanded clutch pressure signal.
