Abstract: An electric vehicle drive system includes an electric motor, first and second planetary gear sets, including sun gear, carrier and ring gear members, first and second output shafts, and a housing. The members of the first planetary gear set are connected with the electric motor, the first output shaft, and a member of the second planetary gear set. The members of the second planetary gear set are connected with the first planetary gear set, the housing, and the second output shaft. The first planetary gear set provides differential reduction and the second planetary gear set provides reversal and reduction. Optional clutches can provide the function of a limited slip differential and distribute torque preferentially to one output shaft or the other.

Abstract: A hybrid vehicle includes an engine drivingly connected to a first pair of drive wheels by a transmission. A first motor generator is coupled to the engine to provide drive torque to the transmission for driving the first pair of drive wheels. A second motor generator is drivingly connected to a flywheel by a planetary gear system. The planetary gear system is connected to a second pair of drive wheels.
