摘  要: 运用功能概念,对汽车防抱死制动系统(ABS)的作用及ABS汽车的紧急制动过程进行了分析.根据功能原理,提出了ABS汽车在平路、上坡、下坡3种不同道路上制动距离的计算方法和公式.分析表明:ABS能防止车轮被制动抱死,提高汽车制动时的方向稳定性和转向操纵能力;ABS汽车在滑动率为15%~20%时获得最大制动力系数,制动距离最短.汽车总质量与制动距离无直接关系,计算方法和结果适合各种ABS汽车,在汽车制动性能分析和公路交通安全分析方面具有实用性.<Abstrcat>The paper analyzes the function of Antilock Braking System (ABS) and the urgent braking course of ABS automobiles with the concept of work-energy. According to the principle of work-energy, the paper proposes the calculating methods and formulas of the braking distance of ABS automobiles on three different kinds of roads such as level roads, up-sloping roads and down-sloping roads. The analysis indicates that ABS can prevent wheels from locking, and raise the direction steadiness and the steering ability of automobiles under hard braking; the ABS automobile obtains maximum braking-force coefficient and needs a much shorter distance to stop at the slipping rate of 15%~20%. As the total mass of an automobile isn't directly related to braking distances, the calculating methods and results suit all ABS automobiles, and are useful for analyzing automobile braking-properties and road traffic-safety.
