摘　　要：分析了汽车制动防抱系统控制中多种参考车速的确定算法,提出了参考车速的自适应斜率算法,给出了其构建方法。进行了大量的试验验证,结果表明该算法大大提高了参考车速确定的准确度及其自适应性,改善了ABS控制效果。In a practical ABS system the vehicle speed can not be determined directly without a correlative sensor equipped. So it is very important to calculate vehicle reference speed exactly in ABS. In this paper, the methods of determination of vehicle reference speed were analyzed, such as the max wheel speed method, the slope method and the adaptive slope method. The merits and defects of each method, as well as their applying conditions, were stated. By the road test of a car modeled VW Jetta GTX, the adaptive slop method showed a better performance.
