奥运场馆用混合动力电动汽车建模与仿真研究

Modeling and Simulation Study of HEV Used in Olympic Gymnasium

为实现2008年北京"绿色奥运"的目标,开发低排放和零排放的电动汽车成为必然。根据奥运场馆用车的特殊要求,通过分析奥运场馆用混合动力电动汽车各子系统的工作原理,建立了相应的数学模型,在此基础上采用图形化建模仿真工具MATLAB/Simulink建立了整车仿真模型,并进行了纯电动和混合动力行驶工况下的仿真分析。结果表明,所确定的参数合理,所制定的控制策略切实可行,能够满足奥运场馆用车的要求,从而为开发奥运场馆用车提供了理论依据,奠定了技术基础。

In order to have a ＂Green Olympic Game＂ in Beijing in 2008, the study on low-emission and zero-emission Electric Vehicles is necessary. On the requirements of vehicles used in Olympic gymnasium, several mathematic models were made by analyzing the principles of all the subsystems of Hybrid Electric Vehicle, and then on this basis, the models were made by using MATLAB/Simulink. The simulation analyzed two types of working conditions in which the vehicle was driven by electric power and hybrid power. The results show that the parameters and the control strategies are reasonable which can meet the requirements of vehicles used in Olympic gymnasium. Theoretic support and technical foundation for designing the vehicles used in Olympic gymnasium were proposed.
