Method and system for controlling a mining and/or construction machine

A system for estimating a level of stress that a mine truck is subjected to, the system being designed to estimate a level of stress of a mine truck comprising:

• a frame;
• a container for carrying payload supported by the frame;
• and
• at least one sensor, the at least one sensor delivering signals being dependent on a force acting on the mine truck;
• the system comprising:
• means for, for at least a first position of the frame, estimating a level of stress that said at least a first position is subjected to in response to a force acting on the mine truck, wherein said at least a first position is a position being different from the position of said at least one sensor;
• means for estimating said level of stress utilising a model representation of the level of stress for said at least a first position, wherein said model representation output said estimated level of stress utilising sensor signals from said at least one sensor as input signals;
• and
• means for utilising different model representations for different positions of the frame of the mine truck, different states of operation of the mine truck, and different levels of load.
