Design of Teaching Platform for ABS Wheel Speed Sensor

Abstract In order to ensure driving safety, ABS brake systems are currently installed on cars. When the ABS is working, it needs to detect the wheel speed signal through the wheel speed sensor to realize continuous braking and relaxation to prevent the wheels from locking up. In daily teaching, it is difficult for students to observe the working process of the wheel speed sensor, and then understand the working condition of ABS in the braking process. So according to the working principle of electromagnetic induction wheel speed sensor, a simple experimental bench was designed and manufactured. This bench can clearly display the changes of the voltage generated by the sensors at different speeds during the rotation of the wheel, and then simulate the changes in the signal when the ABS is working.
