[0002] ABS sensor is the key component in the anti-lock braking system (ABS) of the automobile, which is used to monitor the rotational speed of the wheel to prevent the wheel from locking during emergency braking, thus maintaining the maneuverability and stability of the vehicle. ABS sensor is usually installed near the hub or brake disc of each wheel, and works in cooperation with the gear ring or encoder ring that rotates synchronously with the wheel to generate electrical signals related to the vehicle speed. These signals are transmitted to the ABS control unit (ECU) to realize real-time monitoring of the wheel speed.

[0003] The main functions of ABS sensor include:

[0004] Prevent wheel lock: When the vehicle is braking, the sensor detects the rotational speed of each wheel to determine whether it is about to lock, and sends the signal to the control module. The control module adjusts the braking force to prevent the wheel from locking.

[0005] Tire pressure monitoring: In the indirect tire pressure monitoring system, ABS sensor can compare the number of rotations of the four tires to monitor whether the tire pressure is too high or too low.

[0006] Monitoring tire screw loosening: On some vehicle models, ABS sensor can also sense tire vibration to monitor whether the tire screw is loose, and trigger an alarm through the electronic stability program (ESC) control unit.
