This paper presents methodology for utilizing standard chassis rotary potentiometers to detect payload and tongue weight in a light duty truck application. A design of experiments was performed using different sensor setups, payload locations, road grade, etc to refine an algorithm for accurately detecting the load on the rear axle. The purpose, or benefit, of this detection is two-fold. First, the results of the load calculation can be provided to the end consumer via CAN communication and a visual screen to ensure that max vehicle weight limits are not violated. This provides a measure of safety for vehicle handling and ensures reliability of structural components. Second, the results can be used to develop improved electronically controlled suspension calibrations for ride performance. Instead of relying on the end consumer activating a tow / haul method and having discrete calibration modes these could be modified depending on a multitude of weight detection thresholds. There are other systems in the market which utilize custom, more complex, expensive sensors whereas we approached the solution from an analytical perspective using common industry components.
