1. A method for determining a failure probability of a component of a motor vehicle, the method comprising:

  • monitoring data in the form of damage-relevant influence parameters, which affect the failure probability of the component;

    storing the data during operation of the component; and

    evaluating the influence parameters in a control unit of the motor vehicle to determine the failure probability during the operation of the component, wherein the failure probability is determined within a scope of the evaluating of the influence parameters, by comparing a collective-damage sum, which is a measure of an accumulated loading of the component that is determined with the aid of the influence parameters, and a tolerable-damage sum of the component determined in preliminary stages of the evaluating of the influence parameters.
