Direct determination of the maximum grip coefficient on the basis of measurement of the circumferential extension in a sidewall of a tire
Abstract:
A method of determining the grip coefficient μ in the contact area of a tire on a road includes the steps of selecting a plurality of fixed points in space (that is to say ones that are fixed in the reference frame associated with the vehicle) which points lie at different azimuths along the circumference in at least one sidewall of the tire, obtaining a corresponding number of measurements of circumferential distance variation (extension or contraction) at these fixed points when the tire is rolling on the road, and the measurement signals are processed so as to extract the grip coefficient μ.
Abstract(Chinese):

确定道路上的轮胎的接触区域中的抓地系数μ的方法包括以下步骤：在空间（即，与车辆相关联的参考系中固定的固定点）中选择多个固定点 沿着轮胎的至少一个侧壁中的圆周处于不同的方位角，获得在轮胎在道路上滚动时在这些固定点处的圆周距离变化（延伸或收缩）的相应数量的测量，并且处理测量信号 以提取握力系数μ。
