What does Automatic Traction Control detect?

Automatic Traction Control (ATC) is designed to enhance the vehicle's traction by detecting when there is a loss of drive wheel traction. This system monitors the rotational speed of the wheels and can identify when one or more wheels are slipping or spinning faster than others, which typically occurs during acceleration on slippery surfaces. When ATC detects this loss of traction, it intervenes by reducing engine power or applying brakes to the slipping wheels, helping to restore traction and maintain control of the vehicle. This capability is particularly important for vehicles towing heavy trailers, as maintaining traction is critical for both safety and performance during driving conditions that may compromise grip.
