| 摘 要： | 轮胎与地面间的附着系数是影响车辆安全性能的重要因素.在理论分析的基础上,提出了基于线控制动的路面附着系数检测方法,利用踏板位置传感器估计制动器制动力,采用MMA6260Q加速度传感器检测车辆制动减速度,由制动器制动力与地面制动力判断轮胎运动状态,根据车辆载荷转移公式得到车轮法向载荷,获得进入滑动区域的利用附着系数,并由此得到地面附着系数.分析显示该检测方法可以较准确地识别轮胎与地面附着系数,具有一定的实用价值.

| Abstract: | The adhesion coefficient between tire and road is one of important factors which influence vehicle safety performance. On the basis of theoretical analysis, the detection method of adhesion coefficient based on brake-by-wire is put forward. Brake force is estimated according to pedal position sensor, and vehicle braking deceleration is detected through MMA6260Q acceleration sensor. The motion state of tire is distinguished according to brake force and road braking force, the vertical load of tire is received in view of the formula about vehicle load transfer. Adhesion coefficient used for sliding area is got and is taken as adhesion coefficient of road. Analysis shows that the detection method may identify adhesion coefficient between tire and road accurately, and has certain practical value. |
