1. A method for a powertrain having an engine, a motor, and a transmission, comprising:

  • operating the powertrain according to a motor power loss term that is adapted based on battery power supplied to the motor, motor power output, and an estimated motor power loss such that the motor power loss term changes over time and converges to a constant value to thereby be indicative of actual motor power loss.
