摘　　要：为保证纯电动轻型货车在具有最佳制动力分配的前提下多回收制动能量,仿真模拟了双能量源再生制动系统,设计了理想制动力分配再生制动控制策略。以东风EQ5030轻型货车为原型,根据纯电动轻型货车对能量和功率的双重要求,组成超级电容+蓄电池的双能量源储能结构。利用Matlab/Sumilink软件,建立再生制动系统仿真模型。在典型的道路循环工况下,对两种控制策略进行仿真对比。结果表明:本文设计的理想制动力分配再生制动控制策略比传统并联再生制动控制策略能量回收率提高了37.33%,增加了汽车的续驶里程。A dual-energy-source regenerative braking-system simulation model was established to ensure an electric light-truck recover braking-energy as much as possible within a best braking force distribution. A dual energy source regenerative braking system was simulated to design an ideal braking force distribution of regenerative braking control strategy. A light truck named Dongfeng EQ5030 was taken as the prototype with a super capacitor being introduced into a pure electric-vehicle energy-storage-system to meet the demand of energy and power for a pure electric vehicle light truck. An ideal braking force distribution of regenerative braking control strategy was designed. A simulation model of regenerative braking system was established using the Matlab/Sumilink software to simulate and contrast two different control strategies under typical road cycle. The results show that the energy recovery rate increases by 37.33% than that of the traditional paralel control strategy for the ideal braking force distribution of regenerative braking control strategy designed. It causes electric cars increase travel distance.
