Abstract

A method for determining a mechanical load to which a component was exposed. The component comprises at least one sensor that is arranged in a force flow of the mechanical load and that emits a measurement signal in the event of a mechanical load. The method comprises providing an increase function, which establishes a relationship between the measurement signal and the mechanical load for an increasing load, providing a decrease function, which establishes a relationship between the measurement signal and the mechanical load for a decreasing load, identifying reversal points at which a change in the measurement signal changes a sign, saving the measurement value and the corresponding increase functional value or decrease functional value at the reversal point, providing a new increase function or a new decrease function by displacing and compressing the increase function or the decrease function, wherein the compression is executed with regards to both the measurement signal and the mechanical load, and determining the mechanical load at least also using the saved values.
