The Wheel Speed Sensor is a critical component in modern automotive electronics, specifically within the Vehicle Dynamics Control system under Chassis & Vehicle Dynamics. It measures the rotational speed of each wheel and provides real-time data to the vehicle's control units. This information is essential for maintaining stability, enhancing safety, and improving driving performance.

Wheel speed sensors are widely used in various advanced driver assistance systems (ADAS), such as Anti-lock Braking System (ABS), Electronic Stability Control (ESC), and Traction Control System (TCS). By continuously monitoring wheel speed, these systems can detect and respond to potential skidding, loss of traction, or uneven braking, helping to prevent accidents and improve overall vehicle handling.

In addition to safety features, wheel speed sensors also support functions like cruise control, hill start assist, and automatic transmission shifting. They are typically installed on each wheel hub, either inside the brake drum or mounted on the axle, depending on the vehicle design.

These sensors play a vital role in ensuring reliable and responsive vehicle dynamics, making them an indispensable part of modern automotive electronics. Their accurate and timely data transmission contributes to a safer and more efficient driving experience. Whether in passenger cars, commercial vehicles, or electric vehicles, wheel speed sensors are key to achieving optimal performance and safety.
