面向动态需求的混合动力电动汽车能量模糊控制方法研究

Study on Fuzzy Control Method of Hybrid Electric Vehicle Energy Based on Dynamic Requirement

利用PID和模糊控制两种方法,对并联混合动力电动汽车的动态特性和燃油经济性进行仿真分析。结果表明,与PID控制方法相比,模糊控制方法不但可以满足汽车的动态特性要求,而且可以降低油耗。

By using PID and fuzzy control method,the authors carry out the simulation analysis of HEV＇s dynamic and fuel consumption character.The result shows that the fuzzy control method can not only meet vehicle＇s dynamic requirement,but also reduce the fuel consumption.
