摘要
针对纯电动汽车存在的不足,本文主要对增程式电动汽车动力参数匹配与控制策略进行研究。给出了整车参数及车辆动力参数,并借助AVL-Cruise和Simulink联合仿真平台,对增程式电动汽车动力参数进行匹配,对各部件进行选型,利用Stateflow搭建控制策略,将整车仿真模型和控制系统很好的联系起来并进行仿真验证。仿真结果表明,整车动力参数匹配比较合理,满足基本动力性和经济性要求,控制策略能使动力电池在合理区间工作,实现增程器高效工作,延长电动汽车续驶里程,降低有害气体的排放,与目前存在的公交汽车相比,百公里油耗明显降低。该研究为进一步研究增程式电动汽车提供了理论依据。
In view of the deficiencies of pure electric vehicles,this paper mainly studies the matching and control strategies of power parameters of extended-range electric vehicles.The vehicle parameters and vehicle dynamic parameters are given.Based on the joint simulation platform of AVL Cruise and Simulink,the power parameters of the extended-range electric vehicle are matched,the components are selected,and the control strategy is built using state flow.The vehicle simulation model and the control system are well linked and verified by simulation.The simulation results show that the vehicle's dynamic parameter matching is more reasonable and meets the basic dynamic and economic requirements.The control strategy can make the power battery work in a reasonable range.The efficiency of the range extender is increased,the driving range of the electric vehicle is extended,and the emission of harmful gases is reduced.The fuel consumption per 100 kilometers is significantly lower than that of the existing bus and the research provides a theoretical basis for further research on the extended range electric vehicle.
