研究了汽车制动过程中车速、轮速等的变化过程和影响因素；以化整为零的思想，研究得到制动过程中各物理量间的微分方程关系；进而建立在ABS下的数学模型；继而通过使用simulink建立仿真模型；采取逻辑门限的控制方法，综合仿真的整个动态变化过程；得到车速、轮速、滑移率、路面附着系数和制动距离随时间的变化曲线；最后利用图像分析的方法对各物理量进行分析、比较，对比有无ABS系统下制动距离的变化，得出使用ABS控制策略能显著缩短制动距离，提高制动安全性。数据分析和处理主要应用MATLAB软件。(The braking dynamics model of quarter vehicle ABS is established. It simulates the dynamic behavior of a vehicle under hard braking conditions. We researched the change of the vehicle speed and wheel speed during the vehicle braking. According to Newton s first and second law, then dfferential equations are obtained, so we get the Mathematical model. Next the response of the system is simulated by using Simulink in MATLAB . Based on the logic threshold control, we get the curve that Speed, wheel speed, slip ratio and road adhesion coefficient and brake distance changes over time. Contrasting with ABS or without ABS , using the ABS control strategy can significantly shorten the braking distance. Data analysis and processing mainly used MATLAB software.)
