摘　　要：为了在制动过程中完成当前路面的识别,在Burckhardt轮胎-路面数学模型的基础上设计了6种典型路面峰值附着系数的变化范围,以路面附着系数为参数指标在制动时进行路面识别。使用单轮模型分别在单一路面和跃变路面上进行了仿真试验,结果表明该方法能够准确快速地完成路面识别,充分利用了不同路面的附着条件。最后通过车载六分力测试系统在干沥青路面上进行了道路实验,进一步验证了该方法的有效性和可行性。In order to complete road identification durittg braking, the peak adhesion coefficient variation ranges of six typical roads were designed with the road adhesion coefficient as parameter index to complete dynamic identification of road condition during braking under the mathematical tyre-road model of Burckhardt. Simulation tests about the single road and variational road based on the single-wheel model are conducted separately and it＇ s concluded that road identification can be completed quickly and accurately by this method, the adhesive conditions of different roads are fully utilized. Finally the result of road experiment on dry asphalt by on-board six-component testing system also verified the feasibility and effectiveness of this method.
