摘　　要：以整车燃油经济性的评价为基础,通过分析混合动力汽车动力系统的组成,建立燃油经济性最佳的数学模型。考虑汽车的动力性要求以及动力电池的荷电系数要求,使用复合形优化方法对目标函数进行优化。利用具体车型对优化方法进行验证,使用ADVISOR2002仿真软件对优化前后的汽车性能进行仿真分析。结果表明百公里油耗降低9.02%,经济性得到较大提高,动力性仍然保持设计要求。A mathematical model with objective function of the best fuel performance is built by analyzing the components of HEV based on the evaluation of fuel economy. The objective function is optimized with the complex optimum method in consideration of the dynamic performance of the PHEV and the SOC of the power battery. The optimization method is validated, and the performance is simulated and analyzed by the software ADVISOR2002. The result shows that the 100km fuel consumption is reduced by 9.02%, the fuel economy is highly improved when the dynamical performance keeping design requirement.
