摘　　要：电动汽车制动系统由机械-液压制动和再生制动组成。再生制动指车辆制动时,电机输出反向转矩,辅助车辆制动,同时将车辆的部分动能转换成电能储存在回收装置里。提出一种根据路面附着系数合理分配再生制动力,同时可以最大限度回收回馈能量的再生制动控制策略,该策略可对回馈能量进行有效控制,确保充电安全性。最后进行仿真分析和实验研究,结果证明本策略可使车辆实现稳定制动,并能最大限度回收回馈能量。The electric vehicle brake system consists of a mechanical-hydraulic braking and a regenerativebraking. The regenerative braking means that,when the vehicle brakes,the motor output reverse torque to assistbraking,and at the same time the part of the kinetic energy of the vehicle is converted into electrical energy stored inrecovery unit. A regenerative braking control strategy was proposed,which could allocate the regenerative brakingforce according to road adhesion coefficient and recover the feedback energy maximally,and the regenerative energycould be effectively controlled. Finally,the simulation and experiment was carried out,the results show that thestrategy allows the vehicle to achieve stable braking,and could recover the feedback energy as much as possible.
