Research & Simulation Of Energy Distribution Control System For HEV-C Based On CAN

With rapid development in holding automobiles in the world since the end of 20th century, along with increasingly calling for environmental protection and increasing shortage of oil reserves, the hazard which is caused by conventional internal combustion engine vehicle to human environment would be noticed. Creating high efficient and saving energy power system is brought to the agenda. The perfect zero emission or low emission electric automobile becomes one of the main choices after groping for different new energy.There are three types of Electrical Vehicle has there types: Pure Electrical Vehicle,Hybrid Electrical Vehicle, Fuel Cell Vehicle. The Hybrid Electrical Vehicle is the feasible outcome from new and traditional Automobile technique. It not only has the advantages of low emission and high efficiency of Pure Electrical Vehicle, but also has the performances of long running mileage and fast fuel supplement in tradition internal-combustion engine automobile. Accordingly, Hybrid Electrical Vehicle becomes the feasible scheme for saving energy and protecting environment in this century.The paper is relying on"985"project--The research on Hybrid Electrical Vehicle which is presented by ministry of Science of P. R. China and assumed by Hunan University. The Series-Parallel Hybrid Electric Vehicle based on CVT, whose controllers are communicated by CAN Bus, is developed by Hunan University, Jianglu Rodar Vehicle Transmission Co. ,Ltd .In this paper, the worldwide development of HEV is analyzed. The importance of developing HEV in China along with the characteristic and superiority of combining HEV and CVT are presented. HEV-C power assembly control system and its topology network result are analyzed. The Hybrid Electric Vehicle controller network communication protocol based on CAN Bus of HEV is established on the basis of J1939 protocol and the project. And by using of different ID, the bus conflict can be avoided.Then, the typical HEV power assembly system is deeply analyzed on the basis of the development and research of the currently power assembly system. The mathematics model of combined coupling power assembly based on CVT transmission is built in combination with experimental data and theoretical analysis of theexperimental bench. The professional simulation platform of HEV-C is designed and built by using MATLAB/SIMULINK simulation language. The Hybrid Electric Vehicle Energy Distribution control algorithm based on logic threshold control is studied on the HEV-C simulation bench. The control flow charts of the main controller energy distribute control algorithm are written on the basis of the project. At the same time, the control algorithm based on fuzzy control has been studied on.Finally, the results and graphs of simulation based on HEV-C energy distribute Strategy which can be used for guiding the experiments are contended in the paper.
