The wheel speed sensor is an electromagnetic or optical detection system that measures the speed of wheel rotation and sends a signal to the control unit. This signal is processed by the vehicle electronics to determine whether a wheel is locked or spinning and to control the vehicle's braking behavior accordingly. The wheel speed sensor is an important component for safety-relevant functions of the vehicle, as it supports the ABS and ESP system in preventing accidents and increasing driving safety.
