摘要

以提高电动汽车动力性与经济性为目标,对两挡纯电动汽车传动系速比进行优化设计。以0,8,0 km/h加速时间和ECE-EUDC-LOW循环工况百公里耗电量分别作为电动汽车动力性与经济性的两个分目标函数,建立了双目标函数下的速比优化模型。考虑到换挡规律在速比优化过程中的耦合效应,确定了与速比关联的兼顾动力性与经济性的换挡规律制定准则。设计一种具有非支配比较筛选功能的枚举算法,求取双目标函数的Pareto最优解集。结果表明,相对于初始速比,电动汽车采用某组优化速比时加速时间缩短了3.5%,百公里耗电量降低了2.4%,电动汽车动力性与经济性得到了提高。

Abstract

In order to improve the power performance and fuel economy of the electric vehicle,the transmission ratio optimization design for a two- speed electric vehicle transmission system is studied. The 0 ,8,0km / h acceleration time and hundred kilometers power consumption are respectively taken as two sub- objective functions for dynamics and economic performance. A speed ratio optimization model for the dual objective functions is built. Taking the coupling effect of the shift schedule in optimization process into account,the rule of developing a comprehensive shift strategy,which associates with ratios and considers the dynamic and economic performances is determined. An enumeration algorithm,which has the function of non- dominated comparing and filtering,is designed to obtain the Pareto- optimal solution set for the dual objective function. Finally the proposed electric vehicle with a set of the optimal ratio solutions is compared with this vehicle with the initial ratios. The results show that the acceleration time is shortened by 3. 5% and the energy consumption is decreased by 2. 4%,the power performance and fuel economy of the electric vehicle are improved.
