Abstract: The automobile anti-lock braking system (ABS) adjusts the wheel speed according to the adhesion coefficient and slip ratio curve to achieve the best braking effect. However, the adhesion coefficient and slip rate curves of different roads are different, and the peak value of adhesion coefficient and the corresponding optimal slip rate are also different. In order to achieve better ABS control effect for vehicles on different roads, a method for measuring adhesion coefficient and slip rate curve is proposed in this paper, which can calculate the adhesion coefficient and slip rate curve in real time.

摘要： 汽车防抱死制动系统（ABS）依据附着系数-滑移率曲线对车辆轮速进行调节，使车辆 达到最好的制动效果。但不同路面的附着系数-滑移率曲线不同，且附着系数的峰值和对应的 最佳滑移率也不同。为便于车辆在不同路面均达到更好的 ABS 控制效果，文章提出一种附着 系数-滑移率曲线的测定方法，可实时计算附着系数-滑移率曲线。
