针对现有分布式驱动电动汽车驱、制动系统容量分配多采用四轮平均分配的问题,提出了一种驱、制动系统轴间容量分配的方法。其中,基于动力性的驱动系统前后轴容量分配的目的是改善最大加速度、最大爬坡度和百公里加速时间;基于制动性的电液复合制动系统前后轴容量分配的目的是改善制动距离和平均制动减速度。分析结果表明,提出的驱、制动系统容量分配方法有效改善了车辆的动力性和制动性。

英文摘要：

Most of the existing capacity allocation methods of driving braking systems for distributed drive electric vehicles adopt uniform distribution amongst the four wheels. Therefore, in this paper a novel capacity allocation method was proposed. The capacity allocation of driving system based on the power performance was aimed to improve the maximum acceleration and the maximum gradability and to shorten the 0-100 km/h acceleration time. The capacity allocation method of electro-hydraulic braking system based on the braking performance was aimed to reduce the braking distance and to increase the average braking deceleration. The results of theoretical analysis indicate that the proposed capacity allocation method effectively improves the power performance and braking performance of the vehicle.
