Abstract
A method for mitigating sway of a trailer being towed by a leading vehicle is disclosed. The method may involve using a controller of the vehicle to determine when a trailer sway condition has arisen that requires a mitigating action. The controller may be used to actuate a plurality of brakes of the vehicle, or to increase braking pressure being applied by a driver of the vehicle, when the trailer is detected as swaying toward a centerline of the vehicle from one side or another of the vehicle centerline. The controller may further be used to release the plurality of brakes, or to decrease a braking pressure being commanded by the driver, before the trailer has swayed past the vehicle centerline, and to repeatedly apply and release the vehicle brakes only while the trailer is detected as swaying toward the vehicle centerline, until the trailer sway condition has been mitigated.
