What is the function of a wheel speed sensor in truck systems?

The function of a wheel speed sensor is to measure the rotational speed of the wheel. This data is crucial for various vehicle systems, including antilock braking systems (ABS), traction control, and stability control. By accurately monitoring the speed at which each wheel is rotating, the sensor provides real-time information that can influence the vehicle's handling and safety features.

For example, in the ABS, if a wheel begins to skid, the system can detect the reduction in speed from the sensor and adjust the braking force to that wheel to help maintain control. This capability not only enhances safety but also improves the overall driving experience. Understanding the role of the wheel speed sensor is essential for diagnosing issues related to handling and braking performance in truck systems.
