ABS sensors are small devices, but they play an extremely important role in vehicle safety systems. They are responsible for monitoring the wheel speed, and through a digital signal processing technology, they communicate the result of the measurement to the ABS control module. If different speeds of individual wheels are registered, the ABS pump adjusts the pressure in the system until the wheel rotates again. This process takes place several times every second.
ABS sensors are also responsible for providing information to all advanced vehicle safety systems such as traction control, lane stabilisation, hill descent control and others based on wheel speed control.
