浅述汽车ABS系统中有源和无源轮速传感器的区别

Studied on the Differences between Active and Passive Wheel Speed Sensor in ABS

阐述有源和无源轮速传感器的工作原理、信号特征及信号处理电路三个方面的内容,并进行了优缺点的比较。结论是有源轮速传感器在信号特征及电路处理上远远优于无源轮速传感器,并在许多基于ABS平台的具有安全制动功能的新装置不断得到开发和应用的现况下,必将取代无源轮速传感器。

The working principle, signal characteristics and circuits of active and passive wheel speed sensor were studied, and their advantages and disadvantages were compared. It was concluded that the active wheel speed sensor was far superior to passive wheel speed sensor in signal characteristics and circuits. Active wheel speed sensor will gradually replace the passive wheel speed sensor in the new device being developed and applied.
