Measuring device for a motor vehicle

A process for determining a fatigue value characterizing the fatigue of a motor vehicle component mounted pivotably on a bracket, the process comprising:

• providing a joint connected to said bracket, said joint having a joint housing and a pivot pin mounted movably in said joint housing;
• providing the vehicle component connected to said joint so that said vehicle component is mounted pivotably on said bracket via said joint;
• providing an angle measuring device for determining an angle of said component in relation to said bracket;
• providing an analyzer connected to said angle measuring device;
• determining angle data by consecutive measurement of said angle between said component and said bracket;
• determining acceleration data by double differentiation of said angle data over time;
• determining sign-free force data on the basis of said acceleration data;
• and
• determining the fatigue value by summing up or integrating said sign-free force data over the time.
