摘　　要：电动汽车在实现快速停车的过程中,会出现车辆抱死的可能,为实现纯电机制动防抱死系统(电气ABS)优化控制,以纯电动汽车为研究对象,通过对传统ABS系统进行分析,在Matlab环境下建立了单轮电气ABS模型,提出了以滑移率为门限值的控制策略,采用控制电机电压脉冲宽度调制的控制方法,分析了电动汽车在制动过程中电机三种不同的状态,分别为能耗制动、反接制动和再生制动,最终选择了反接制动、再生制动和电机驱动3种不同的状态来实现电气ABS。仿真结果表明电气ABS能够有效的防止车轮抱死,所运用的控制策略取具有良好的控制效果。In achieving rapid parking processing, electric vehicle may be locked. In order to achieve the pure motor anti -lock braking （Electrical ABS） control, treating the purely electric vehicles as research object, based on the traditional ABS systems analysis, a single wheel electric ABS model was built withMatlab/Simulink. A slip rate threshold control strategy was proposed, and the control of motor voltage PWM duty cycle method was used. Motor＇s three states in the braking process of the electric vehicle were analysed, which were the dynamic braking, reverse braking and regenerative braking. Finally, three conditions： reverse braking, regenerative braking and motor driving, were chosen to realize the electrical ABS. The simulation results show that the electrical ABS can effectively prevent the wheels from locking, and the results has achieved good control effect by using the control strategy in this paper.
