The purpose of this paper is to describe the design and simulation of the urban vehicle power train system of the University of Wisconsin at Madison. The objective of the power train is high fuel efficiency as well as low emissions.

Fuel efficiency is achieved by an on-off operation of the internal combustion engine with the “on” operation at only the minimum brake specific fuel consumption area. Emission control is partially achieved by utilizing an electric drive system for transient response. Furthermore, low emissions and fuel efficiency are bettered by techniques such as special starting without choke, no deceleration, and no idle requirements on the internal combustion engine.
