轮胎故障是造成交通事故的主要原因之一 .但是目前大多数轮胎故障监测方法由于需要使用各种复杂的传感器因此制造代价高昂且不可靠 .为此 ,提出了一种新型实用的轮胎故障观测器 .基于考虑外界不确定干扰的新型动态轮胎 /路面磨擦模型 ,该观测器仅仅使用汽车驱动力及轮胎转速数据 ,跟踪估计轮胎 /路面磨擦系数的变化 ,并通过对磨擦状况的分析对轮胎状态做出合理的判断 .由于转速传感器是汽车防滑刹车控制系统 (ABS)的基本组成部分 ,因此该观测器可与ABS结合工作 ,低成本的实现轮胎故障监测 .
Tire failure is one of the major causes of traffic accidents.However, most current tire fault monitoring methods are expensive and unreliable because of the need to use a variety of complex sensors.Therefore, a new and practical tire fault observer Based on the new dynamic tire / pavement friction model considering uncertainties in the outside world, the observer tracks the tire / pavement friction coefficient only by using the driving force of the vehicle and the tire speed data, and analyzes the condition of the tire to do the tire condition Reasonable Judgment Since the speed sensor is an integral part of the ABS, this observer works in conjunction with ABS to achieve low cost tire monitoring.
