PROBLEM TO BE SOLVED: To provide a vehicle propulsion system that has a continuously variable transmission (CVT) while reducing the size, cost and inefficiency.SOLUTION: A vehicle propulsion system (12) includes an electric machine (EM) (16) configured to generate an unconditioned output; and a CVT (14) having an input side (20) and an output side (22), the input side mechanically coupled to the EM (16) and configured to receive the unconditioned output from the EM (16) and produce a conditioned output on the output side (22). A fixed-ratio transmission (40) is mechanically coupled to the output side (22) of the CVT (14) and configured to receive the conditioned output from the CVT (14) and produce a reconditioned output.SELECTED DRAWING: Figure 1 【課題】サイズ、コスト及び効率低下を軽減した連続可変トランスミッション（ＣＶＴ）を有する車両推進システムを提供する。【解決手段】車両推進システム（１２）は非条件付け出力を発生させる電気式機械（ＥＭ）（１６）と、入力側（２０）及び出力側（２２）を有するＣＶＴ（１４）であって、該入力側はＥＭ（１６）に対して機械的に結合されると共にＥＭ（１６）からの非条件付け出力を受け取り該出力側（２２）上に条件付け出力を生成するＣＶＴ（１４）を含む。ＣＶＴ（１４）の出力側（２２）には固定比トランスミッション（４０）が機械的に結合されており、該固定比トランスミッション（４０）はＣＶＴ（１４）から条件付け出力を受け取りかつ再条件付け出力を生成する。【選択図】図１
