轮速传感器的研究及应用

Research and Application of Wheel Speed Sensor

主要论述一种轮速传感器,它分为无源磁电被动式传感器和有源霍尔主动式传感器,是以导体和磁场发生相对运动而产生电动势为基础的。它安装于车轮上,主要为ABS(防抱死制动系统)开发的。为了防止车轮抱死,控制程序必须知道单个车轮的速度,足以可见,轮速传感器在汽车上的重要性。

This paper mainly discusses a kind of wheel speed sensor, which is divided into passive magnetoelectronic passive sensor and active Hall sensor. It is based on the electromotive force generated by the relative motion of conductor and magnetic field. It is installed on wheels, mainly developed for ABS(Anti-lock Braking System). In order to prevent the wheel from locking, the control program must know the speed of a single wheel,enough to see the importance of the wheel speed sensor in the car.
