Achieving a Low CO2 Emissions Hybrid Vehicle with a Well to Wheel Approach

A parallel hybrid drive train, consisting of a downsized IC-engine, an automated gearbox and an electric motor is being designed at the University of Liege and Breuer Technical Development, Belgium.

Objectives of the concept are the reduction of CO₂ emissions without performances loss and a zero-emission driving mode in inner cities. The battery can be connected to the mains for recharging.

This paper presents the original management strategy that minimizes CO₂ emissions over the complete energy supply, from well to wheel. Metropol, a homemade software, simulates energy consumption and emissions on different driving cycles.
