Abstract:

Environmentally friendly ground vehicles with range and performance capabilities surpassing those of conventional vehicles require a careful balance among competing goals of fuel efficiency, performance and emissions. The research objective here is to integrate hybrid electric vehicle simulations with high-fidelity engine modules to increase the accuracy of predictions and to allow design studies in the concept evaluation stage. This paper describes a methodology for integrating vehicle and engine simulations. The feed-forward model of the engine is modified to allow its linking with the vehicle model and an engine component scaling routine is added to facilitate system sizing studies. As design optimization framework is then used to find the best overall engine size, battery pack and motor combination for minimum fuel consumption within proposed US government performance criteria.
