Abstract

Systems and methods for an electric drive unit are provided. A transmission system, in one example, includes a higher-lower range clutch assembly positioned downstream of a multi-speed clutch assembly and designed to shift the transmission system between a higher range operating mode and a lower range operating mode. The higher-lower range clutch assembly includes a lower range clutch and a higher range clutch each positioned on one of a first layshaft and an output shaft.
