利用Simulink软件建立车辆防抱死制动系统的仿真模型；基于PID控制原理设计以车轮滑移率为控制对象的防抱死制动系统控制器，对防抱死制动控制系统进行仿真。将普通制动系统与防抱死制动系统仿真结果进行对比，结果表明PID控制的防抱死制动系统能有效提高车辆的方向操纵性和制动效能。%Firstly, the simulation model of Anti-lock braking system is established by the software of simulink; Secondly, this paper designs a kind of Anti-lock Braking System (ABS) controll system and targeted at the wheel slip ratio based on the PID control strategy, which simulated the system of ABS and analysed the result. The simulation results of the ordinary brake system is contrasted with the Anti-lock braking system, and the results show that PID control ofAnti-lock braking system can effectively improve the direction of the vehicle maneuverability and braking performance.
