| 摘 要： | 针对某款紧凑型纯电动汽车的设计要求,以整车动力性和经济性为匹配目标,运用汽车纵向动力学理论确定驱动电机型号和动力电池参数。在动力系统速比的约束下,完成了固定速比变速器、两挡电控机械式自动变速器(AMT)动力传动2种方案的设计。利用Cruise软件平台搭建整车动力系统模型,对NEDC循环工况续驶巡航、100km/h加速时间以及最大爬坡度等工况进行了仿真试验。结果表明,所设计的传动方案均能满足整车性能设计要求,动力系统参数选取合理。通过方案对比分析,两挡AMT在整车动力性和经济性上都优于固定速比变速器。

| Abstract: | According to the design requirements of a compact pure electric vehicle,matching of the dynamic performance and economy as the target,driving Motor Type and Power Battery parameters were determined by the theory of vehicle longitudinal dynamics.Under the constraint of transmission gear ratio,the fixed speed ratio transmission and two gears Automatic Manual Transmission(AMT)drive scheme were designed.The Cruise software platform was used to build the vehicle dynamic system model,the simulation tests of the driving range of NEDC cycle,100km/h acceleration time and maximum ability were carried out.The results show that the designed transmission scheme meet the requirements of design targets,the Dynamic Systems parameters are selected reasonably.Compared with different schemes,the two gears AMT is superior to the fixed speed ratio transmission in terms of dynamic performance and economy. |
