摘要
A method to control a powertrain having an electric motor includes monitoring a torque command to the motor, predicting a motor torque for the motor based upon the torque command, monitoring an actual motor torque of the motor, comparing the actual motor torque to the predicted torque, and indicating a motor fault when the actual motor torque and the predicted torque differ by more than a calibratable threshold.
