| Abstract: | An InSb magneto-resistive wheel speed sensor is introduced. And its circuit for signal processing is designed, which involves two-stage band-pass filters and hysteresis comparator. This sensor has simple structure and low cost. The experiment shows that magneto-resistive wheel speed sensor is reliable. Also it has high sensitivity and can minimize the effect of electromagnetic interference. It is suitable for the variety from high speed to low speed. It can be widely used in ABS. |
