Energy Distribution Strategy And CAN Communication About The HEV Based On CVT

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 from environment in this century.In this paper, the worldwide development of HEV is analyzed. Along with the characteristic and superiority of combining HEV and CVT, the importance of developing HEV in China is presented. The typical HEV power assembly system is deeply analyzed on the basis of the development and study of the currently power assembly system. The mathematics model of combined coupling power assembly is built in combination with experimental data and theoretical analysis of the experimental bench. The professional simulation platform of CVT-HEV is designed and built by using MATLAB/SIMULINK simulation language.Then, the Hybrid Electric Vehicle Energy Management control algorithm based on logic threshold control method is studied on the CVT-HEV simulation bench. The control flow charts of the main controller energy management algorithm is written on the basis of the project. At the same time, the control algorithm based on fuzzy control has been studied on. The results and graphs of simulation based on CVT-HEV Energy Management Strategy which can be used for guiding the experiments are contended in the paper.Finally, the network's topology of CVT-HEV power assembly control system is analyzed. Considering the practical project, the CAN Bus controller network communication protocol of HEV is established on the basis of J1939 protocol. Later on, the hardware and software of CAN module and the contronl node of liquid crystal display are developed.
