Abstract
Nowadays in the automobile sector, seeking reductions in emission and fuel consumption in Hybrid Electric Vehicles (HEVs) is an increased focus. In different architectures of HEVs the most favourable architecture is a series-parallel HEV, because of its high operation modes and performance as it joins the advantages of both series and parallel HEVs. In spite of its advantages, this system is more complex and intricate to model. Lying in the heart of this type of architecture is the planetary gear which has a vital role because of its power distribution. This paper aims to reduce the complexity of the system with a modelling comparison of the planetary gear for a series-parallel HEV by both structural and functional approaches. In order to describe the two modelling approaches, Energetic Macroscopic Representation (EMR) is used for the functional approach and Simdriveline by MATLAB-Simulink™ for the structural modelling approach. These two different topologies are shown and discussed through simulation results.
