Abstract
A method detects the wear state of a component of a door drive system of a rail vehicle. The method includes reading 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. The method additionally includes checking whether a value which represents the sequence of the first motor parameters satisfies a specified criterion in order to detect the wear state of the component of the door drive system.
