摘要
通过对内燃机典型万有特性曲线进行研究,以发动机效率优化为依据,提出了一种以并联式混合动力汽车(Parallel Hybrid Electric Vehicle,简称PHEV)需求扭矩、电池荷电状态和发动机转速为输入,发动机的实际输出扭矩为输出的并联式混合动力汽车模糊控制策略。并在EUDC路况下进行了仿真。结果表明,所设计的模糊控制策略在满足车辆动力性能指标的前提下,与电辅助控制策略相比,PHEV的平均耗油量降低了11.5%,发动机效率提高了7%,证明了该策略的有效性。
After investigation of a typical specific fuel consumption map for internal combustion engine（ICE）,based on instantaneous engine efficiency optimization,a fuzzy control strategy was proposed for PHEV.The required torque,the battery state of charge（SOC） and the engine speed were considered as the inputs to the fuzzy control where the output of the fuzzy control was the actual output torque delivered by ICE.The optimization results were provided for EUDC driving cycle.The results from the computer simulation show the fuzzy control can meet the vehicle performance,and comparing with the electric assist control strategy,the average fuel consumption is reduced by 11.5%,and the ICE efficiency is improved by 7%.
