Principles of Signal Generation in ABS Sensors

ABS sensors operate based on the principle of electromagnetic induction to generate signals indicative of wheel speed. Typically, these sensors consist of a coil and a magnet, where variations in the magnetic field produce electrical signals. When a metal target, such as a tone ring or reluctor wheel, passes by, it distorts the magnetic flux. This distortion induces a voltage in the coil, producing an AC signal that corresponds to wheel rotation.

The frequency and amplitude of this signal directly relate to the wheel’s rotational speed and can be processed to detect slipping or locking situations. Since signal quality is vital for accurate ABS operation, understanding how signals are generated helps optimize sensor placement and calibration.
