Abstract: The present invention relates to a method for determining the door position in a door system which has a rail for guiding a movable door element and a sensor element (10) for detecting a free movement path of the door element (50), the method comprising the steps of: detecting the state of the at least one sensor element (10), which can either be free of the door element (50) or covered by the door element (50), such that, in the event of a change in the state of the sensor element (10), the arrangement position of the sensor element (10) corresponds to the door element (50), and a door control lines the door position with the aid of this information.

Abstract: A door control unit for controlling the actuation of a door. In at least one example, the door control unit may comprise a drive unit which is designed to output actuation signals for a door, and a computer unit which has a connection with the drive unit and is designed to communicate with an actuating unit for the door, wherein the computer unit furthermore is designed to operate an operating system which utilizes a software module for the communication with the actuating unit.
