Establishment and Analysis of a Simulation Model for the Two-Mode Hybrid Electric Vehicle

Hongwei Cai

Abstract

The two-mode hybrid(TMH) system jointly developed by General Motors,Daimler-Chrysler and BMW companies was token as study object in this paper.By using Matlab/Simulink,secondary development was made based on the model of the first-generation Prius,which can be found in the simulation software ADVISOR.The model of vehicle speed calculation,as well as the model of the key component of the power system was built.Through this way,a simulation platform for the two-mode hybrid electric vehicle was created.An advanced control strategy,combined with electric assistant control and fuzzy logic control,was proposed.At last,the urban dynamometer driving schedule(UDDS) and city-suburban heavy vehicle route(CSHVR) were chosen as the testing driving cycle.With the comparison of the simulation results of the Toyota Prius,it is easily to find that two-mode hybrid vehicle has very good fuel economy while maintaining reasonable emission characters.
