    摘要: 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.

    摘要: The present disclosure is directed toward sway control systems for adjustably controlling sway between a trailer and towing vehicle through use of frictional forces that include a tow bar assembly, a connector assembly, a tensioner spanning the width of the housing of the tow bar assembly, and a crank assembly. Within the tow bar assembly, a slide bar is frictionally engaged with the housing, and the relative friction may be controlled by increasing or decreasing compression of the at least one brake pad through adjustment of the compression plate toward or away from the interconnecting web. The present disclosure attempts to improve ease of use by utilizing a single adjustment point.
