Abstract
A method for operating a door system having a door leaf, which is movable by a door actuator, and having a sensor unit, which is arranged at a height above a floor of the door system and with which the approach of a person towards the door leaf is detected by a control unit, includes at least the following steps: determining a direct distance between the sensor unit and the person using the sensor unit; determining a horizontal distance between the sensor unit and the door leaf by a geometric relationship of the person, of the door leaf and of the height of the sensor unit; and determining the probable approach time of the person on the basis of the determined horizontal distance and opening the door leaf. A door system having a control unit may be used to carry out the method.
