| At present, atmosphere pollution is worse and worse in the world. Petroleum resource is less and less. Hybrid Electric Vehicle(HEV) resolve the energy-saving and environmental protection of vehicles. And HEV satisfies the combined demand, such as less releasing, less oil wear, higher cost performance. Thus HEV becomes the developing hotpot of every big manufacturing enterprises of vehicles in the world.Firstly, according to the kinetics equation, control-oriented mathematical model, the quasi-stationary simulink model of drive system is set up, including the bodywork of vehicle, engine, electric motor, electric generator, battery, gear box, and so on. Secondly, on the MVEG-95 driving cycle, a model is built according to the configuration of parallel hybrid electric vehicles(PHEV) transmission system. On the Japan 10-mode driving cycle, a model is built according to the configuration of series hybrid electric vehicles(SHEV) transmission system. Compared with the conventional vehicle of similar dynamic performance, the fuel economy of the parallel hybrid electric vehicle increase above 30%, and the deviation of SOC is kept at a low level, which fully prove the validity of the control strategy.Then the emulational data and results of MATLAB output is demonstrated with MCGS configuration software. It is realized that the real-time data communication between MATLAB and MCGS by DDE. The alternation of every emulational parameter and power real-time flow and distribution in the whole course can be observed in MCGS surface. Through the Excel link toolbox and ACCESS database, it is realized that the historical data communication between MATLAB and MCGS. The emulational results can be displayed visually in MCGS.The perfect visual technologies of MCGS and excellent computational function of MATLAB are combined in this paper. The visual man-machine condition which can be observed multi-angle and multi-level emulational course is provided for users. |
