Abstract
A method is disclosed for managing power in a hybrid electric vehicle powertrain having multiple components, including at least two of a group comprising an engine, a motor, a generator and a high voltage battery. Power losses in the individual components are computed. An engine operating speed and torque for a given vehicle speed and total power command is determined so that total power losses for powertrain components are minimized.
