In the 《Automobile industry policy》of 2004 version , Our country have pointed out to develop the technique of Hybrid Electric Vehicle . In this thesis, firstly introducing the importance of development the Hybrid Electric Vehicle on the basis of checking the large quantity of domestic and international data, analyzing the domestic and international present condition of Hybrid Electric Vehicle, introducing the advantage of Hybrid Electric Vehicle. Then further analyzing kinds of problems needed resolving on Hybrid Electric Vehicle at present. Secondly, introducing the work principle of Hybrid Electric Vehicle, then regarding one kind of Hybrid Electric Vehicle as the research object, established the mathematics model of whole car ′motive and economic and its each statures system. On the basis of above work, application the tool box of MATLAB/ SIMULINK developed the software of automotive function in Hybrid Electric Vehicle. Analyzing on the known circulation condition the claim of Hybrid Electric Vehicle to the speed and power of electrical machine, to the power of the storage battery and the engine. Finally, contrast introduce the storage battery of every type , combining to describe the work principle of the sour battery in lead and establish in details the theories modle of charge and discharge characters of the sour battery in lead .Because the electri
