通过实验研究带防抱死制动系统车辆刹车痕迹形态特征。选取22辆不同小型乘用车在不同路面进行刹车实验,采集制动减速度与时间关系曲线,观察测量刹车痕迹形态特征,得出防抱死系统车辆刹车痕迹留痕时间在一般制动力上升至最大之后,痕迹形态受不同刹车条件影响很大,要顺光、远点、低角度进行观察的结论。 The experimental study of the shape of braking marks on vehicles with anti-lock brake system. Twenty-two different small passenger cars were chosen to carry out braking experiments on different road surfaces. The braking deceleration versus time curve was collected, and the morphological characteristics of the braking traces were observed. The brake traces of the anti-lock braking system were obtained. After the maximum, the shape of the trace is greatly affected by different braking conditions, and the conclusions to be observed along the light, the far point and the low angle.
