【摘要】 针对目前电动汽车(EVS)续驶里程短的问题,从车辆动力学的角度建立了较为系统的续驶里程计算模型。讨论了电动汽车动力传动系统参数设计和整车质量对续驶里程的影响,并以XL2000型纯电动轿车为研究对象,分析计算了匹配两种不同传动系统时的续驶里程,并给出了计算结果。进一步的实验表明,计算结果与实验值误差小于5%,验证了所建模型的合理性。在样车设计阶段,利用该方法进行仿真研究,具有一定的参考价值和指导意义。更多还原

【Abstract】 In view of the weak point in driving range of electric vehicles (EVS), the more systemic calculation model of driving range is proposed in the EVS dynamics aspect. Influence of the parameters design in power train and gross mass of EVS on the driving range is discussed. Based on the type of XL2000, the driving range is calculated and analysed in matching to the two sorts of different power trains. The calculation results are listed. Test results ulteriorly indicate that the error is smaller than 5% between calculated results and test datum. The rationality of established model is verified. It has reference value and guiding meaning for making simulation study using this method in the sample design of EVS.更多还原
