Computer modelling of the automotive energy requirements for internal combustion engine and battery electric-powered vehicles

In the paper the road vehicle simulation package Janus, developed in the Engineering Department at Durham University, is described. Janus is a flexible simulation package that allows internal combustion engine vehicles, electric vehicles and hybrid vehicles to be simulated, and their performance and energy consumption evaluated over standard driving cycles. The simulation techniques used in these programs are described and the simulation program shown to produce results comparable with experimental data.
