ABSTRACT:
An integrated power transmission has an internal combustion (IC) for engine power input, an electrical motor power input and a combining planetary transmission coupled with both power inputs. The power transmission also includes a multi-speed transmission input. The combining planetary transmission can be driven by the electric motor input only with a one-way device providing a reaction path for the combining planetary transmission and a stationary power input at the IC engine. A friction clutch member is provided to selectively establish a drive path including both power input members in a multi-speed transmission input. This clutch permits both power sources, electrical and internal combustion, to provide power to the combining planetary and also permits starting of the IC engine while the vehicle is in motion.
