Method and control unit for determining the probability of failure of a motor-vehicle component
First Claim
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.

Abstract
A method and control unit for determining the failure probability of a component of a motor-vehicle. Data in the form of damage-relevant influence parameters, which affect the failure probability of the component, are measured and stored during the operation of the component. To ascertain the failure probability, a collective loading is calculated as a determining influence parameter for establishing the fatigue limit of the component. To determine the collective loading as realistically as possible and therefore determine the failure probability as accurately as possible, the influence parameters may be evaluated during the operation of the component, in a control unit of the motor-vehicle for determining the failure probability.
