Abstract
A system for trailer loading suspension sway and rollaway (TLSR) detection in a vehicle includes a trailer attached to a vehicle via a hitch. Sensors detect a load on vehicle suspension. A TLSR application monitors vehicle state information, determines that initialization conditions have been met, and monitors, via the sensors, vertical loads on front and rear vehicle axles. The TLSR application determines rear axle vertical load and generates at least one of: an overload alert, a sway alert, and a rollaway alert. Upon generating at least one of the overload alert, sway alert, and rollaway alert, the TLSR application notifies a vehicle operator that a vertical load exerted by the trailer has exceeded a positive load threshold, a calibratable minimum negative load threshold, and/or a calibratable negative rear axle load threshold unless and until none of the thresholds have been exceeded.
