摘　　要：为进一步提高新型插电式混合动力汽车(PHEV)的整车经济性,考虑到影响整车经济性的2个主要因素——行驶工况和行驶里程,提出了变参数能量管理策略。为减小车辆行驶工况的影响,应用模糊欧几里德贴近度方法,建立了基于典型循环工况的车辆行驶工况识别控制策略;为减小车辆行驶里程的影响,应用模糊识别的方法,建立了以车辆行驶里程和车辆启动时的动力电池荷电状态(SOC)为输入,行驶里程模式为输出的车辆里程模式识别控制策略;最后对整车能量管理策略进行了仿真分析。结果表明:在同等行驶里程的新欧洲行驶循环(NEDC)工况下,与定参数能量管理策略相比,变参数能量管理策略可以降低整车等效百公里油耗5%以上,从而提高了PHEV的整车经济性。To further improve the economy of a novel plug-in hybrid electric vehicle（PHEV）,a variable parameter energy management strategy was proposed based on driving cycle and trip distance,which would influence the vehicle economy.To reduce the influence of driving cycle,fuzzy Euclid’s degree of nearness was used to establish the driving cycle recognition control strategy based on typical driving cycles.To reduce the influence of trip distance,the vehicle trip distance mode recognition control strategy was proposed by using fuzzy recognition,with the trip distance and the power battery SOC of vehicle at start as inputs and the trip distance mode as output.Eventually,the simulation for energy management strategy was carried out for analysis.The results show that compared with the constant parameter energy management strategy,the equivalent fuel consumption of PHEV under the condition of the variable parameter energy management in the same distance of new European driving cycle（NEDC）can be reduced by more than 5%.The variable parameter energy management strategy can be used to improve the economy of PHEV.
