Review of Electronic-continuously Variable Transmission Propulsion System for Full Hybrid Electric Vehicles

Abstract

In this paper, the electronic-continuously variable transmission (E-CVT) propulsion system for full hybrid electric vehicles (HEVs) is reviewed. Firstly, the E-CVT propulsion systems are classified as two main groups, namely the gear E-CVT and the gearless E-CVT. Consequently, the development of E-CVT propulsion systems is discussed, with emphasis on their system architecture, principle of operation, merits and drawbacks. Finally, the development trend of E-CVT propulsion systems will be briefed.
