在simulink环境下对汽车防抱死制动系统进行数学建模,采用基于车轮加、减速度门限值及参考滑移率的控制策略,控制器以车轮的角加、减速度和滑移率的大小为输入,根据输入值的大小控制器输出相应的信号给制动模型,进而对轮速和滑移率进行调节,使其在理想范围内.对汽车ABS模型进行仿真研究,通过得出的仿真曲线,验证了ABS制动系统拥有良好的制动性和操纵性.

Mathematical modeling to the automotive anti-look braking system was built based on simulink.It adopted the wheel add,substract speed threshold method and referenced slip ratio control strategy.The size of the wheel angular velocity and slip ratio study were input into the controler,the corresponding signal was output to the model of the brake based on the size of the input value to adjust the wheel speed and slip ratio.Simulation was carried out on the automobile ABS model and simulation curve was obtained.The results confirmed that the ABS braking system has good brake and maneuverability.
