Abstract:
A drive system includes a first gear set and a second gear set, each including a sun gear, a ring gear, a plurality of planetary gears coupling the sun gear to the ring gear, and a carrier rotationally supporting the plurality of planetary gears, a first electrical machine coupled to the sun gear of the first gear set, a second electrical machine coupled to the sun gear of the second gear set, a connecting shaft coupled to the ring gear of the first gear set, a driveshaft that transports power from the electrical machines to a tractive element, a first clutch selectively rotationally coupling the first carrier and the second carrier to the driveshaft, and at least one of a second clutch selectively rotationally coupling the second electrical machine to the connecting shaft and a third clutch selectively rotationally coupling the second gear set to the driveshaft.

Claim (Index 1):
A drive system for a vehicle, comprising:\n a first gear set including a first sun gear, a first ring gear, a first plurality of planetary gears coupling the first sun gear to the first ring gear, and a first carrier rotationally supporting the first plurality of planetary gears; a second gear set including a second sun gear, a second ring gear, a second plurality of planetary gears coupling the second sun gear to the second ring gear, and a second carrier rotationally supporting the second plurality of planetary gears, wherein the first carrier is directly coupled to the second carrier; a first electrical machine directly coupled to the first sun gear of the first gear set; a second electrical machine directly coupled to the second sun gear of the second gear set; a connecting shaft coupled to the first ring gear of the first gear set; a driveshaft configured to transport power from the first electrical machine and the second electrical machine to a tractive element of the vehicle; a first clutch selectively rotationally coupling the first carrier and the second carrier to the driveshaft when engaged; and at least one of:\n a second clutch selectively rotationally coupling the second electrical machine to the connecting shaft when engaged; and \n a third clutch selectively rotationally coupling the second gear set to the driveshaft when engaged.
