Abstract:
1. A transmission comprising: a first planetary gear set providing at least part of a first torque path from an input shaft to an output shaft; a second planetary gear set connected in parallel with the first planetary gear set and providing at least part of a second torque path from the input shaft to the output shaft; a plurality of gears configured to transmit torque selectively from the first torque path to the output shaft, and to transmit torque selectively from the second torque path to the output shaft; a first coupling configurable to couple both a primary power source and a first secondary power source to the input shaft; and a second coupling configurable to couple a second secondary power source to the output shaft, wherein when the primary power source and the first secondary power source are decoupled from the input shaft, the output shaft is configured to receive torque solely from the second secondary power source.
