摘要:
提出将一款固定速比传动的纯电动汽车改为两挡传动的方案,分析了满足整车性能指标要求的动力传动系统部件主要参数的匹配方法.为了验证参数匹配的合理性,分别制定了动力性换挡规律和经济性换挡规律,通过Matlab/Simulink建立的整车性能仿真平台,对不同换挡规律下的整车动力性和续驶里程进行了仿真.仿真结果表明,动力系统参数匹配合理,满足整车动力性和续驶里程要求;其中经济性换挡规律下的NEDC工况续驶里程比动力性换挡规律下高0.14%;动力性换挡规律下百公里加速时间比经济性换挡规律下缩短了6.02% .
Abstract:
A pure electric vehicle with a fixed speed ratio was changed into two gear transmission scheme.Thematching method of main parameters for powertrain components was analyzed based on specifications of vehicleperformance.In order to prove that the parameter matching is reasonable,the dynamic shift schedule and the e-conomy shift schedule were formulated.Through the vehicle performance simulation platform which was estab-lished under Matlab/Simulink,the vehicle dynamic performance and the driving range under the different shiftscneaue were simuLalea. Ine simuaion resuIs snow nat ne parameter maicnng is reasonane,ana tne powerperformance and the driving range can meet the design requirements.The driving range of the NEDC conditionunder economy shift schedule is 0.14% higher than under the dynamic shift schedule. The acceleration time in100km under the dynamic shift schedule decreased by 6.02% than under the economy shift schedule.
