System and method for preventing trailer sway

A method of operating a tow vehicle and a trailer to prevent trailer sway. The method includes detecting a predetermined maneuver for the tow vehicle and the trailer based on operating parameters. The predetermined maneuver corresponds to a subset of operating parameters from the plurality of operating parameters. A critical speed is determined based on the subset of operating parameters. The critical speed corresponds to a speed of the tow vehicle and trailer where a damping between the tow vehicle and the trailer cannot prevent trailer sway. A vehicle control is adjusted for the tow vehicle based on the critical speed.
