| 摘 要： | 在MF轮胎模型的基础上，针对影响路面附着系数的因素，详尽分析了在6种典型路面上滑移率与附着系数之间的关系，提出了利用轮速等汽车动力学参数便捷识别路面状态的方法。该方法在典型路面特性的基础上，将估计的路面附着系数与典型路面的特性进行比较，并给出路面的状态。最后在直线制动工况下模拟了该路面状态识别方法在分离路面和组合路面上的可靠性和有效性。结果表明该方法能够较好地识别路面的状态。

| Abstract: | The relationship of wheel slip ratio and road adhesion coefficient was analyzed with the application of the magic formula tire model. An approach for road identification based on wheel velocity and other vehicle dynamic parameters was developed. The road characteristics were determined by the comparison of the estimated road adhesion coefficient and the characteristics of the regular road surface conditions. In order to illustrate the accuracy and effectiveness of the approach, two simulations of straight line braking were conducted on split and tessellated road surfaces, respectively. The simulation results showed that the approach could identify road surface condition well. |
