What is the main function of ATC?

The main function of an Automatic Traction Control (ATC) system is to transfer power to the drive wheels when traction is lost. This is essential for maintaining stability and control of the vehicle in slippery or challenging driving conditions. When the ATC system detects that one or more wheels are slipping—such as on ice, snow, or gravel—it adjusts the power distribution to ensure that the wheels with better traction receive more power. This helps to prevent loss of control and promotes safer driving by enhancing the vehicle's ability to maintain traction.

In addition to this primary function, ATC can also work in conjunction with other traction and stability systems, providing a more comprehensive approach to vehicle control. While improving fuel efficiency, reducing engine power, and preventing wheel lockup are all important aspects of vehicle performance and safety, they do not encompass the specific role that ATC plays in managing traction under varying conditions. Thus, the emphasis on transferring power to the drive wheels is what defines the core functionality of the ATC system.
