Patent ID: 8651989

Claim:
A transmission comprising: a transmission input shaft; a first planetary gear set comprising: a first sun gear, at least two first pinion gears meshed with the first sun gear, a first carrier coupled to the at least two first pinion gears and the transmission input shaft, and a first ring gear meshed with the at least two first pinion gears; a first electric motor coupled to the first sun gear; a second electric motor coupled to the first ring gear; and an output gear selectively coupled to the first electric motor to provide a first transmission gear ratio and selectively coupled to the second electric motor to provide a second transmission gear ratio; a first driver gear selectively coupled to the first electric motor and meshed with a first driven gear, the first driven gear being coupled to the output gear; a second driver gear selectively coupled to the second electric motor and meshed with a second driven gear, the second driven gear being coupled to the output gear; a reverse driver gear selectively coupled to the second electric motor; a reverse idler gear meshed with the reverse driver gear; and a reverse driven gear meshed with the reverse idler gear, the reverse driven gear being coupled to the output gear to provide a reverse gear ratio.
