This work presents an investigation of the influence of different
modeling approaches on the quality of fuel economy simulations of hybrid
electric powertrains. The main focus is on the challenge to accurately
include transient effects and reduce the computation time of complex
models. Methods for the composition of entire powertrain models are
analyzed as well as the modeling of the individual components internal
combustion engine and battery. The results shall help with the selection
of suitable models for specific simulation tasks and provide a deeper
understanding of the dynamic processes within simulations of hybrid
electric vehicles.
