Abstract:
1. An independent trailer sway controller configured to be mounted on a trailer, the independent trailer sway controller comprising: a first electrical connector operable to selectively couple the independent trailer sway controller to an electrically-actuated frictional trailer braking system; a second electrical connector operable to selectively couple the independent trailer sway controller to a hydraulically-actuated frictional trailer braking system; trailer length input operable to receive length data indicating a length of the trailer and output the length data; a sway sensor operable to sense sway of the trailer and output sway data; a trailer sway detector module operable to receive the length data and the sway data, determine a level of trailer sway based on the length data and the sway data, determine whether the level of trailer sway exceeds a predetermined threshold, and output a trailer sway condition signal if the level of trailer sway exceeds the predetermined threshold; and a brake controller module operable to receive the trailer sway condition signal and, in response, output a brake enable signal over at least one of the first electrical connector and the second electrical connector to be received by a trailer braking unit to enable a trailer brake to apply braking force to one or more trailer wheels to mitigate trailer sway.
