摘　　要：分析了车轮附着系数和滑移率的关系,研究了汽车防抱死制动系统(Antilock Brake System,ABS)对制动距离的影响。结果表明:ABS对车轮滑移率的精确控制,使每个车轮始终保持在最佳的滑移率范围;充分利用轮胎与地面的附着系数,获得稳定和最大的制动减速度;缩短制动时间和制动距离,对车辆的安全性能大大提升。The relation between wheel adhesion coefficient and slip rate was analyzed,and the influence of ABS on braking distance was studied.The results show that the precise control of the wheel slip rate by ABS keeps each wheel always in the optimal range of slip rate,making full use of the adhesion coefficient between the tire and the ground to obtain stability and maximum braking deceleration,shorten braking time and braking distance,greatly improve the safety performance of the vehicle.
