摘　　要：为解决某后驱纯电动汽车续航能力不足的问题,提出基于制动I曲线的并联混合制动力分配控制策略。在满足制动I曲线、f曲线以及ECE法规的前提下,分析ABS、车速、电池SOC等因素对再生制动的影响以及不同制动强度下制动力的分配情况,并通过Simulink搭建制动力分配控制策略模型,联合Cruise整车模型进行仿真。结果表明:在NEDC工况下制动能量回收效率为19.6%,续航里程贡献度达21%,整车续航里程提升约52 km。To solve the problem of insufficient endurance of a rear-drive pure electric vehicle,a paral⁃lel hybrid braking force distribution control strategy based on braking I curve was proposed.On the premise of braking I curve,f curve and ECE regulation curve,the impact of ABS,vehicle speed,SOC of battery and other factors on regenerative braking,and the distribution of braking force between front and rear wheels and motor under different braking intensity were analyzed.The model of braking force distribution control strategy was constructed by Simulink,and co-simulation was carried out in AVL Cruise vehicle model.The results show that under NEDC condition,the braking energy recovery effi⁃ciency is 19.6%and the driving range contribution is 21%,the range of the vehicle is increased by about 52 km.
