Abstract:
A vehicle drive includes a first gear set and a second gear set both having a sun gear, a ring gear and planetary gears which couple the sun gear to the ring gear. The planetary gears of both sets are rotatably supported by respective planetary gear carriers which are coupled to each other. The vehicle drive also includes an engine, a first clutch which selectively engages the engine to the ring gear of the first gear set, a first motor/generator coupled to the sun gear of the first gear set and a second motor/generator coupled to the sun gear of the second gear set and electrically coupled to the first motor/generator, a second clutch which selectively engages the engine to the second motor/generator, and a third clutch and a third gear set which operate to selectively engage the ring gear of the second gear set to the planetary gear carriers.
