Abstract
A system for determining the load on each axle of a vehicle (150) uses load cells (130, 140) mounted on the bed of the vehicle (150) at load-bearing locations that are longitudinally spaced apart from the axles. Axle weight for each axle is determined from the load cell output signals based upon the moments about the effective longitudinal center point of each axle assembly, and the load-bearing points at which the load cells are mounted. System calibration is effected by using load cell signals when the vehicle (150) is unloaded and load cell signals when the vehicle (150) is loaded.
