Abstract

A control system and control method for a hybrid electric vehicle powertrain having an engine, an electric motor and an electric generator with gearing for effecting split power distribution from separate power sources. Power delivery to vehicle traction wheels is coordinated to meet a driver's demand for power as much as possible without violating predefined maximum and minimum powertrain limits, including the limits of the battery subsystem.
