A SIMULATION FOR INVESTIGATION OF HYBRID VEHICLE CONCEPTS

This note outlines a dynamic system simulation for a heat engine/electric hybrid road vehicle, based on work by Ricardo and the Volvo Car Corporation. The simulation model was developed using the Simulink extension to Mathwork's Matlab package. It is well suited to hybrid vehicle simulation, and has several relevant advantages. The model's use is illustrated by results based on the Volvo Environmental Concept Car (ECC), developed to explore many ways of reducing the environmental impact of a practical family car. The ECC can use a diesel-fuelled high-speed gas turbine generator in a hybrid vehicle configuration, where the gas turbine can be decoupled from the wheels and operated under optimal running conditions to generate electric power. Volvo's calculations of total life environmental load, compared with that of a conventional family car, showed reductions ranging from 20%, using only an on-board generator and diesel fuel, to 70% with a mix of 70% hydro-electric power and 30% on-board generated power. The resulting performance depends very much on the total system's behaviour, in terms of component interactions and control algorithms. Thus the use of dynamic system simulation is essential for a cost-effective investigation of the widest possible range of options. For the covering abstract see IRRD 865940.
