The Modeling And Simulation Of HEV Based On Bond Graph

Firstly, this paper gives an analysis on the type and hybrid configurations of hybrid electric vehicle, and summarizes the characters of all the driving types and their working conditions. Through the introducing of common simulation software of HEV in world, and takes ADVISOR as an example, show the advantage and disadvantage of working the simulation software in china. The fact point out that we must develop the simulation software of HEV suitable for the china's actual condition.Secondly, introduce the basic theory of the bond graph, show out the advantage of simulating the characters of multi-power and multi-type of HEV using bond graph. In order to test this point, I analyze the driving system of Honda Insight and Toyota PRIUS based on the application of bond graph, and establishes the mathematic models. The MATLAB/SIMULINK is used to visual programming it. The simulation results show that using the bond graph could not only reflect the dynamic characteristic in effect, but also having the following advantages.1) Based on the commonness of the multi-power field, using the uniform mathematic analyze way, programming the software from beginning , holding the key technology.2) Based on the application of the bond graph, analyze the characters of engine , motor ,battery and vehicle, uniform the electric power , heat power and mechanical power into the same mathematic model in order to alter the types and parameters of hybrid electric vehicle in convenience.3) The system based on the bond system can also simulate in different direction.Lastly, give some advices for the development of the simulation software of the hybrid electric vehicle in the future.
