Abstract
An electro-mechanical hybrid powertrain uses the electric motor during engine starting. A planetary gear arrangement is disposed in torque transmitting relation between the prime mover, the electric motor and the transmission output. A pair of brake members, which are self-engaging, are provided to establish reaction members in the planetary gear arrangement during engine starting. A fluid-operated piston selectively enforces disengagement of the brakes after the engine has started.
