Abstract
A trailer sway intervention system. The trailer sway intervention system includes a trailer having a plurality of wheels, each wheel having a brake, and a vehicle towing the trailer. The vehicle includes a plurality of sensors configured to sense operating characteristics of the vehicle, and a controller. The controller receives the sensed operating characteristics from the sensors, determines an error based on a difference between an expected yaw rate and a sensed yaw rate, asymmetrically applies braking forces to one or more trailer wheels based on the difference, and symmetrically applies braking forces to the trailer wheels when the absolute value of the difference between the expected yaw rate and the sensed yaw rate is declining.
