Abstract:
1. A hybrid electric powertrain for an automotive vehicle comprising: an engine, an electric motor, a battery, a generator and transmission gearing; the transmission gearing defining in part a first power flow path from the engine to a power output member; the generator being mechanically coupled to the engine by the transmission gearing; the motor, the battery and the generator being electrically coupled and defining in part an electro-mechanical power flow path to the power output member; a generator torque reaction brake means for anchoring the generator when the electro-mechanical power flow path is disabled; and a slipping clutch mechanically connecting a torque reaction element of the gearing to the generator whereby a mechanical power flow path from the engine to the power output member is maintained when the electro-mechanical power flow path is disabled.
