Abstract
A method and system for determining the weight of a load when the load is placed on a chassis supported by a spring suspension. The method comprises measuring a first distance to a position fixed relative the ground by at least one sensor mounted on the chassis; detecting a displacement of the chassis relative to the position based on the first distance and a second distance measured to the position by the at least one sensor; determining the weight of the load on the basis of the chassis displacement; and communicating the determined weight of the load. The system comprises at least one sensor mounted on the chassis for measuring a first distance to a position fixed relative to the ground; a module for detecting a displacement of the chassis relative to the position based on the first distance and a second distance measured to the position by the at least one sensor, the module determining the weight of the load on the basis of the chassis displacement; and a communication module for communicating the determined weight of the load.
