Abstract: In this paper, three different modelling and simulation methods (forward dynamic, quasi-static backwards, and inverse dynamic) will be compared and the simulation results using these methods will be analysed. From a Forward Dynamic (FDM) model, a Forward Quasi-static (FQM) and a Backward Quasi-static Model (BQM) for the engine will be derived. The difference in simulation results for the vehicle used on representative driving cycles will be discussed. The forward dynamic model contains a scalable engine model based on physical laws. The accuracy of this model will be investigated by comparing simulation results with measured quasi-static efficiency data of actual engines.

Keywords: dynamic modelling; simulation; engine scaling; computation time; powertrains; propulsion systems; driving cycles.
