Abstract

A method and apparatus for calculating the axle load on a motor vehicle having at least one axle, wherein the axle is coupled to the vehicle body, or the like, by a spring assembly. The frequency of the vibrations of the vehicle body opposite the axle that occur when driving are measured. The frequency measurements are in turn used to calculate a first axle load. A second axle load is calculated based on the displacement of the vehicle body relative to the axle due to the axle load. The first and second axle loads are evaluated to calculate a final axle load.
