Abstract
A method of controlling a vehicle involves determining if the vehicle is swaying (e.g., if a trailer being towed by the vehicle is exerting a sway force on the vehicle), and if the vehicle is swaying, reducing a torque of an engine of the vehicle and applying independent braking forces to each wheel of the vehicle. A vehicle for controlling vehicle sway includes an engine, a plurality of wheels, a braking system configured to apply independent braking forces to each wheel, and a controller configured to control the engine and the braking system. The controller is configured to determine if the vehicle is swaying (e.g., if a trailer being towed by the vehicle is exerting a sway force on the vehicle), and if the vehicle is swaying, reducing a torque of the engine and applying independent braking forces to each wheel.
