对ABS控制中路面识别的重要性和路面识别的方法进行了介绍,对单个车轮在制动过程中的受力情况进行了分析,由此提出了基于估计车身减速度的路面识别方法,指出在路面识别过程中将制动力系数的变化率略大于零的时刻作为保压时刻.进行了大量的实车试验,试验结果表明,利用以上方法可以在ABS的控制过程中较准确的对路面进行识别.
對ABS控製中路麵識彆的重要性和路麵識彆的方法進行瞭介紹,對單箇車輪在製動過程中的受力情況進行瞭分析,由此提齣瞭基于估計車身減速度的路麵識彆方法,指齣在路麵識彆過程中將製動力繫數的變化率略大于零的時刻作為保壓時刻.進行瞭大量的實車試驗,試驗結果錶明,利用以上方法可以在ABS的控製過程中較準確的對路麵進行識彆.

The importance and methods of road condition identification during ABS control processing were introduced. The method of ABS road condition identification based on body deceleration was put forward according to single wheel force analysis during braking. In - vehicle tests were done, the braking pressure was kept when brake force coefficient change rate slightly greater than 0. Tests showed that the road condition can be exactly i-dentified during ABS control processing with this method.
