Kevin R Carlstrom, Gerald L Larson, Matthew J Gumbel: System and method for vehicle axle load measurement with hysteresis compensation and acceleration filter. International Truck Intellectual Property Company, Jeffrey P Calfa, Dennis Kelly Sullivan, Susan L Lukasik, October 12, 2004: US06803530 (9 worldwide citation)

Vehicle on-board measurement of axle load and gross combined vehicle weight is improved for an air bladder suspended vehicle by allowing for suspension hysteresis. Suspension hysteresis results in at least two distinct air pressures being possible in an air bladder for a single load. The system also ...
