Abstract
A drive train for a vehicle includes an engine having an output shaft, a first gear set including a sun gear, a ring gear and planetary gears coupling the sun gear to the ring gear, a second gear set including a sun gear, a ring gear and planetary gears coupling the sun gear to the ring gear, a first motor/generator coupled to the first gear set, a second motor/generator coupled to the second gear set and electrically coupled to the first motor/generator, a first clutch that selectively engages the output shaft of the engine with the second motor/generator, and a second clutch and a third gear set that cooperate to selectively engage the ring gear of the second gear set with the planetary gear carrier of at least one of the first gear set and the second gear set.
