摘　　要：以滑移率区间[0,0.16]上附着系数曲线的封闭面积作为参数指标,在Burckhardt轮胎—路面模型的基础上设计了7种典型路面的识别区间,据此在制动时完成路面识别。使用制动单轮模型进行了仿真试验,结果表明:该方法只需一次判定即可完成识别,识别快速准确,能充分利用不同路面的附着条件,提高车辆的制动效能。In order to complete road identification, identification intervals of seven typical roads were de- signed with the closed area of adhesion coefficient curve on the slip rate interval [0,0.16] as parameter index under the tyre-road model of Burckhardt. The simulation tests based on brake single wheel model show this method is capable of managing to conduct road identification accurately and immediately, and a single judgment can complete recognition. The method can make best use of the adhesive conditions of different roads and improve the braking efficiency of vehicle.
