摘要
以四川汽车工业集团野马混合动力电动汽车设计要求为基础,提出了一种混合动力电动汽车模糊逻辑控制策略。这种策略通过对油耗和各排放参数动态地分配权重值确定出发动机的最佳转矩,然后再根据模糊控制原理,以电池SOC值、汽车驱动需求的输出转矩和电动机转速为模糊输入确定出发动机的实际输出转矩,最终实现整车油耗和排放的综合优化。通过在S imu link软件中搭建该控制策略的仿真模型并与基础的电力辅助控制策略相比较,证明了这种控制策略有利于整车运行经济性和环保性的提高。
A Fuzzy Logic Control （FLC） strategy for hybrid electric vehicle （HEV） is put forward based on the design requirements of Yema HEV of Sichuan Automotive Industry Group. In the control strategy, an optimal torque of IC engine is determined by dynamically choosing a set of weights on fuel consumption and emissions of different pollutants. Then based on the battery SOC, the required driving torque and the rotation speed of electric motor as fuzzy inputs, the actual output torque of IC Engine is determined by FLC principle. And the overall optimization on fuel consumption and emissions of complete vehicle is finally realized. The comparison of simulation model for the control strategy established by software Simulink with baseline electric assist control strategy shows that the FLC is more effective for improving fuel economy and emissions of complete vehicle.
