Where is the car ABS sensor located?
1 Answers
Car ABS sensors are located on the inner side of the car tires and can be seen when the vehicle is lifted. The ABS sensor is used in the anti-lock braking system of motor vehicles, mostly using inductive sensors to monitor vehicle speed. By interacting with a toothed ring that rotates synchronously with the wheel, the ABS sensor outputs a set of quasi-sinusoidal AC signals whose frequency and amplitude are related to wheel speed. This output signal is transmitted to the ABS electronic control unit to achieve real-time monitoring of wheel speed. There are three types of ABS sensors: linear wheel speed sensors, ring-type wheel speed sensors, and Hall-effect wheel speed sensors. Linear wheel speed sensors mainly consist of permanent magnets, pole shafts, induction coils, and toothed rings; ring-type wheel speed sensors mainly consist of permanent magnets, induction coils, and toothed rings; Hall-effect wheel speed sensors consist of sensing heads and toothed rings.
