Modeling and simulation of hybrid electric vehicles using HEVSIM and ADVISOR

Abstract

This paper discusses a simulation and modeling package developed at Wuhan University of Technology, HEV Simulator (HEVSIM). HEVSIM was written in the Matlab/Simulink graphical simulation language and is portable to most computer platforms. First, comparisons are made for three different hybrid electric topologies according to their power assembly, power-train, control strategies and drive cycles. Then it has been reviewed that two different modeling and simulation methods, the forward- and backward- facing simulation approaches. The modeling and simulation capabilities of existing tools such as ADvanced VehIcle SimulatOR (ADVISOR), HEVSIM are demonstrated through application examples. Differences are given between HEVSIM and ADVISOR2002 based on the two simulation methods. A series HEV and a parallel HEV drive train have been designed using the ADVISOR and HEVSIM respectively. Simulation results such as fuel consumption, vehicle emissions, and complexity are illustrated and discussed for each vehicle.
