The document discusses the traction control system (TCS), which is an active safety feature designed to maintain tire traction in slippery conditions, with its development tracing back to 1971. It outlines how TCS operates through the vehicle’s ECU by adjusting ignition timing, fuel supply, and throttle control based on wheel speed differences, thus enhancing vehicle stability and safety. While TCS is beneficial in various terrains and helps prevent accidents, it has limitations in snow and slippery conditions and is typically found in high-end vehicles with higher maintenance costs.
