Abstract
A dual clutch transmission (DCT) control module includes a pressure determination module that determines a measured pre-charge pressure of an accumulator. A motor control module determines an actual pre-charge pressure based on the measured pre-charge pressure, stored previous pre-charge pressures, and ambient temperature, and controls a pump motor based on the actual pre-charge pressure.
