The Audi A4 ABS Sensor is a capable wheel speed detector. It helps the brake control unit disable wheel lockup for a stable stop. Located adjacent to a toothed ring mounted on a wheel hub, axle shaft, or differential ring gear, the ABS Sensor reads the rotation of each wheel. The sensor generates an alternating current voltage which the control module uses to compare wheel speeds. In the event that one wheel experiences a more rapid deceleration in comparison to the other wheels when braking occurs, pressure is reduced by the module on the hydraulic brake of the corresponding wheel. By doing this, the module ensures that the wheel continues to rotate instead of skidding. The operating principle relies on the moving past an ABS Sensor tip of the ring teeth as a source of magnetic field variation. The variation provides an electric signal that carries speed information. They both work on the same principle of monitoring the position of a moving ring without contact. There are two internal designs usually applied for this purpose. One uses a magnet and a Hall effect element. The other uses a toothed wheel and electromagnetic coil. The slow rotation of the vehicle means that the magnetic field is changing slowly. This causes the voltage to be weak and the accuracy poor. It may also cause data transmission delay when the vehicle is nearly stationary. Notwithstanding this demerit of low-speed issue, the ABS Sensor is crucial to every Audi A4 brake system with anti lock control to achieve safer and more predictable stopping power on all surfaces. Audi drivers receive up-to-date responses from their wheel speeds so the system will be ready to act. This small electronic component illustrates Audi's commitment to A4 line sensing technology while maintaining some overall Audi brake operation familiarity.
