摘要
本文中介绍了一种基于嵌入式平台的轮胎垂直载荷数据采集与信号处理系统设计方案。在轮胎内部嵌装了MEMS加速度、胎压和温度传感器,以获取轮胎径向加速度、胎压和温度等基础实时数据,并从中提取特征信息来表征轮胎垂向载荷。分别进行了室内台架试验和实车试验,对多种工况下的智能轮胎的垂向载荷测量方法和特征提取算法进行了验证。结果表明,基于智能轮胎的垂向载荷测量方法可行,精度满足工程应用要求。
A scheme of the data acquisition of tire vertical load and the design of signal processing system is presented in this paper based on embedded platform.Specifically,MEMS sensors are embedded inside the tires to obtain their basic real-time data of radial acceleration,pressure and temperature,from which characteristic information is extracted to represent tire vertical load.Then bench test and real vehicle test are conducted respectively to verify the measurement method of vertical load of intelligent tire and characteristics extraction algorithm.The results show that the vertical load measurement method of intelligent tire is feasible,with its accuracy meeting the requirements of engineering application.
