US Patent 10300928 Trailer load monitoring

Methods and systems for monitoring a load in a trailer coupled to a vehicle. One method includes determining, with an electronic processor, an initial weight on a rear axle of the vehicle when the load is engaged with the trailer coupled to the vehicle. The method also includes monitoring, with the electronic processor, a current weight on the rear axle of the vehicle based on data collected by a sensor. The method also includes comparing, with the electronic processor, the initial weight and the current weight. The method also includes automatically generating, with the electronic processor, a notification when the current weight is different than the initial weight by a predetermined threshold.
