Abstract
A system and method for a multi-speed electric axle. The multi-speed electric axle includes, in one example, an electric machine rotationally coupled to an input shaft, a planetary gear set including a ring gear meshed with a gear fixedly coupled to the input shaft and a carrier that is rotationally coupled to a shaft, a first clutch configured to selectively ground a sun gear in the first planetary gear set, and a second clutch configured to selectively rotationally couple a sun gear in the planetary gear set with the shaft.
