摘　　要：分析了汽车防抱死制动系统中参考车速的多种确定方法。在分析了各种方法优、缺点的基础上提出了一种综合法,并利用该方法进行了首次制动循环和常规制动循环参考车速的计算。道路试验结果表明,采用该综合法确定的参考车速与车速仪测得的实际车速之间的偏差最大值为4.53 km/h,均差为0.35 km/h,从而验证了采用该综合法确定汽车防抱死制动系统中参考车速的准确性。Many methods to determine reference speed of automotive ABS system is analyzed in the paper,in which a comprehensive method is proposed based on advantages and disadvantages of these methods,and this method is used in calculation of automotive reference speed in the initial braking cycle and conventional braking cycles.The results of road test indicate that the greatest deviation between the reference speed obtained with this comprehensive method and the actual vehicle speed measured with tachograph is 4.53 km/h,with mean deviation of 0.35 km/h,verifying accuracy of reference speed of ABS system obtained with this comprehensive method.
