ABSTRACT:
A method is disclosed for enhancing reverse driving torque in a hybrid electric vehicle powertrain in which an electric motor is used for providing forward driving torque as well as reverse driving torque. An electric generator, functioning as a motor, supplies an added reverse driving torque using a gearset in which the engine provides a reverse driving reaction torque for the gearset.
