Research on Braking Energy Recovery Control Strategy of In-wheel Electric Drive Vehicle

本文以四轮轮毂电驱动汽车为研究对象,针对其续航能力不足等缺点,选用模糊控制对制动能量回收控制策略进行设计,利用Amesim和Simulink软件建立整车控制仿真模型并进行联合仿真。设置不同工况进行仿真,结果表明:所设计的制动能量回收控制策略在保证车辆制动性能的同时,提高了能量回收效率,并减少了动力电池荷电SOC值的损耗,为提高续航能力及减少能量消耗提供一定的研究基础。

Taking four-wheel hub electric drive vehicle as the research object,aiming at its shortcomings such as insufficient endurance,the control strategy of brake energy recovery is designed by using fuzzy control,and the whole vehicle control simulation model is established and co-simulated by using Amesim and Simulink software.The simulation results under different conditions show that the designed brake energy recovery control strategy not only guarantees the braking performance of the vehicle,but also improves the energy recovery efficiency and reduces the loss of SOC value of the power battery,which provides a certain research basis for improving the endurance capacity and reducing energy consumption.
