摘要 通过对纯电动小型城市物流车的改装和实验,为解决电动车单次充电后行驶里程不足的问题,对其引入再生制动系统。在车辆安全制动的前提下,对物流车前后轴的制动力进行合理分配,以获得良好的能量回收效率。根据永磁同步电机和蓄电池的工作特性,对分配策略进行优化。在MATLAB中建立电动物流车的各部分模型,并在ECE-EUDS混合行驶工况下进行仿真。仿真结果表明:该种制动力分配方法回收能量的效率明显高于ADVISOR自带的并联控制策略,安全性能有了很大提高。 Based on the modification and experiment of the pure electric mini logistics vehicle, to solve the problem of insufficient driving range of electric vehicle after charging, the system of braking energy recovery is introduced. The power of the front and rear axle is allocated reasonably to obtain good energy recovery efficiency in the principle of vehicle safety braking. According to the working characteristics of motor and battery, the distribution strategy is optimized. The model of electric vehicle is built in the MATLAB and the simulated in ECE-EUDS driving cycle. The simulation results show that this brake force distribution has a better effect of barking energy recovery than original control strategy of ADVISOR, security peyote has been greatly improved.
