1. A method for detecting a state of wear of a component of a door drive system of a rail vehicle, wherein the method comprises:
reading in a sequence of first motor parameters and second motor parameters, wherein the first motor parameters represent a different physical variable of a motor of the door drive system than the second motor parameters; and
testing whether a value which represents the sequence of the first motor parameters satisfies a predetermined criterion in order to detect the state of wear of the component of the door drive system.
