Abstract: A method for the maintenance of vehicle components is disclosed. The operating points of a plurality of vehicle components are captured over a first time period ?t1 and first developments of the plurality of operating points over time in the first time period ?t1 are determined. The operating points of the plurality of vehicle components are captured over a second time period ?t2 different from the first time period ?t1 and second developments of the plurality of operating points over time in the second time period ?t2 are determined. By comparing the first developments and the second developments of the operating points of the plurality of vehicle components over time, it is determined whether the second development of the operating point of a vehicle component over time deviates from the first development of the operating point of said vehicle component over time by more than a predefined limit value.
