摘　　要：采用查表法和解析法建立了并联式混合动力电动汽车的发动机、蓄电池和电动机的模型。提出了基于发动机燃油经济性,并考虑到废气排放,分不同综合工况的目标函数,对发动机的工作点进行优化处理。利用模糊控制技术,实现了蓄电池的荷电状态值、发动机的期望转矩、以及发动机优化转矩三者之间的合理匹配。仿真结果表明,较之传统的并联电气辅助控制,模糊优化能够更好地提高燃油经济性,并且各种排放也得到了很好的抑制。An Internal Combustion Engine (IC Engine), Battery and Electrical Machine of parallel Hybrid Electrical Vehicle (HEV) are modeled. A comprehensive objective function based on the efficiency of IC Engine as well as the emissions is applied, and the IC Engine working curves are optimized. Based on the battery SOC constraints and the road load conditions (drivers request), the actual output torque is computed by a fuzzy logical controller. From the results of simulation results compared with Parallel Electrical Assistant Control strategy, this control strategy improves on the comprehensive level between the efficiency and emissions, and the consumption of fuel and emissions are decreased obviously.
