Description

TECHNICAL FIELD

[0002] Wheel speed sensor is one of the most important sensors in modern cars, which is responsible for detecting the rotational speed of the wheels. This information is crucial for vehicle dynamic control systems such as Anti-lock Braking System (ABS), Traction Control System (TCS), and Electronic Stability Program (ESP). Wheel speed sensors with axial calibration function can measure wheel speed more accurately, even when there is a certain offset between the sensor and the hub axis.

[0003] The working principle of wheel speed sensor is usually based on electromagnetic induction or Hall effect. Magnetic wheel speed sensors use the change of magnetic flux to generate induced electromotive force, while Hall wheel speed sensors use Hall effect to generate Hall electromotive force when the magnetic field changes.
