8P0498621A Wheel Hub for Audi

A vital application of modern wheel hub units is integrating wheel speed sensors for ABS and ESC systems. The built - in encoder ring and sensor continuously transmit real - time wheel rotation data to the vehicle's ECU. During emergency braking, the system uses this data to detect impending lock - up, modulating brake pressure per wheel to prevent skidding. It also aids traction control by identifying wheel spin. This integration enhances driving safety on slippery roads, shortens braking distances, and is standard on passenger cars and commercial vehicles, ensuring reliable operation in diverse driving conditions.
