摘要
虚拟传感技术用于估计系统中不能或者难以直接放置传感器的位置处的物理量的大小。本文介绍以虚拟传感理论为基础的轮胎压力监测系统,从不同的角度建立相关参数的轮胎模型,利用ABS轮速传感器获取的轮速信号,通过相应的算法来间接实现对轮速的监测。分别运用有效滚动半径、扭转刚度以及纵向刚度等参量,通过不同的算法来监测气压的变化,并预测了今后发展的趋势。
The virtual sensing technology is applied to estimate signals where direct sensors can not be placed. A tire pressure monitoring system based on the theory of virtual sensing is introduced. Signals from ABS, effective rolling radius, torsional stiffness and longitudinal stiffness are all used as parameters to monitor tire pressure. The developing trend is also predicted here.
