ABSTRACT:
A method to control a powertrain including a transmission, an engine, and an electric machine includes monitoring a rotational speed of the engine, monitoring a temperature of a transmission fluid, determining a maximum hydraulic pressure within a hydraulic control system based upon the rotational speed of the engine and the temperature of the transmission fluid, determining a predicted clutch torque capacity based upon the maximum hydraulic pressure, generating a preferred input torque from the engine based upon the predicted clutch torque capacity, and utilizing the preferred input torque to control the engine.
