Abstract

Systems and methods for transmission systems for electric vehicles are provided. In one example, a transmission system is provided that comprises an input shaft rotationally coupled with a first electric motor and a second electric motor, the input shaft having a second clutch; an intermediate shaft having a first clutch and a mechanical clutch system, where the intermediate shaft is selectively coupled to the input shaft via the second clutch or via the first clutch; an idler shaft selectively coupled to the intermediate shaft via a low output of the mechanical clutch system or via a high output of the mechanical clutch system; and an output shaft rotationally coupled with the idler shaft.
