Abstract

An electro-mechanical transmission has interconnected simple planetary gear sets having one member connected to each of a pair of motor/generators and another member connectible with an engine through a selectively operable torque transmitting device. Three additional selectively operable torque transmitting devices cooperate with the gear sets, engine and/or the motor/generators to provide three modes of electro-mechanical power transmissions. One of the motor/generators is stationary, at one speed point in each of two modes, thereby providing two high efficiency operating points.
