Abstract
A method for dampening trailer sway, includes: receiving, by a controller of a vehicle system that is coupled to a trailer, a vehicle speed signal of the vehicle system, wherein the vehicle speed signal is indicative of a vehicle speed of the vehicle system; determining a friction force to be applied to the trailer by an actuator using the vehicle speed of the vehicle system and a graph that establishes a relationship between the friction force to be applied to the trailer and the vehicle speed; and adjusting, by the controller, the graph that establishes the relationship between the friction force and the vehicle speed using the decay rate of the plurality of oscillation amplitudes to create an updated graph.
