A method for state-based maintenance of an access device of a vehicle, in particular of a public transport vehicle, wherein the access device includes a moveable element and an electric drive for moving the moveable element and is attached to the vehicle. The drive is controlled with control signals, wherein actual state signals for describing the state are generated based on a detected state of the access device. The control signals are applied to a physical simulation model for computationally simulating the access device and determining expected target state signals and wherein based on a comparison between the actual state signals and associated target state signals, a maintenance state of the access device is determined. The simulation model is adjusted based on the comparison between the actual state signals and the associated target state signals.
