This paper presents a small urban plug-in hybrid electric vehicle whose propulsion architecture includes a conventional internal combustion engine connected with a continuously variable transmission in the front wheels and two in-wheel electric machines in the rear wheels. Various operation modes, including zero emission vehicle mode, boost mode, and regenerative braking mode, are possible with this solution. In this paper, the authors describe the different components used in the vehicle and the different operating modes. First experimental results, in particular the ones concerning the regenerative braking, are shortly presented at the end of the digest.
