Abstract

A vehicle propulsion system includes an electric machine (EM) configured to generate an unconditioned output. The vehicle propulsion system also includes a continuously variable transmission (CVT) having an input side and an output side, the input side mechanically coupled to the EM and configured to receive the unconditioned output from the EM and produce a conditioned output on the output side. A fixed-ratio transmission is mechanically coupled to the output side of the CVT and configured to receive the conditioned output from the CVT and produce a reconditioned output.
