This document presents a topic seminar on traction control systems. It discusses what traction and traction control systems are, provides a block diagram of how a TRAC system works, and describes how it controls wheel speed. Benefits include avoiding accidents on slippery surfaces by reducing wheel slippage and improving stopping distances. Traction control is useful for powerful cars, motorcycles, and off-road vehicles. While it improves safety, it can increase brake wear and limit performance driving by restricting wheel slip to 10%.
