Abstract
An independent trailer sway controller and method for mitigating trailer sway. The independent trailer sway controller is a modular unit swappable between different trailer types. The independent trailer sway controller includes a trailer length input for receiving length data indicating a length of the trailer and a sway sensor for measuring sway movement of the trailer. The independent trailer sway controller also includes a trailer sway detector module that receives the length data and sway data and determines a level of trailer sway based on the length data and sway data. If the level of trailer sway exceeds the predetermined threshold, a brake controller outputs control signals that activate trailer brakes, which are part of an electric brake system or hydraulic brake system.
