    DETAILED DESCRIPTION OF THE DRAWINGS

    [0028] A door system 100 is shown in each of FIGS. 1 and 2 which has a door leaf 10 which can be automatically opened with a door actuator 1. A person 11 is represented before the door system 100 and approaches the door system 100 at a speed v.

    [0029] The approach is recorded with a sensor unit 12 which is particularly advantageously designed as a radar sensor. Therefore, the sensor unit 12 can detect not only the mere presence of the person 11, but an approach speed, an approach direction and, if applicable, also the size of the person 11, can also be detected with a sensor unit 12 having a radar sensor. The recorded sensor data of the sensor unit 12 is then transmitted to a control unit 13 which is for example part of the door actuator 1, but can also be arranged externally to the door actuator 1. Lastly, the control unit 13 serves to actuate the door actuator 1 in order to initiate a movement in the door leaf 10 and consequently to open and close the same.

    [0030] FIG. 1 shows the person 11 without an interaction with the door leaf 10, whereas FIG. 2 shows by way of example that the person 11 actuates the door leaf 10 by hand in addition to the automatic actuation by the door actuator 1. This manual actuation is detected by the door actuator 1 and a correction value is determined in order to perform a correction for future pivot movements of the door leaf 10 in such manner that the person 11 is, as far as possible, no longer compelled to interact with the door leaf 10.

    [0031] FIGS. 3 and 4 show by way of example a non-manual or non-tactile way of interacting with the door leaf 10. A walking speed v of the person 11 over a time tin seconds s is shown, with the person 11 first approaching the door system 100 at a roughly constant speed until a door opening time TO. The behavior of the person 11 can be recorded by means of the sensor unit 12 and transmitted to the control unit 13.

    [0032] FIG. 3 shows by way of example a door opening time TO which is stored such that the person 11 must increase their walking speed in order to ultimately reach a passage time D in which the door leaf 10 is still open. As a result, it can be read from this diagram that either the door opening time TO is designed to be too early or the door leaf 10 closes again although the passage time D of the person when passing through the door system 100 is still not reached. This interaction can be recorded by means of the sensor unit 13. FIG. 4, in contrast, shows a door opening time TO which is stored such that the person must reduce the walking speed v in order to for example wait for the door to open in order to ultimately pass the door system 100.

    [0033] Therefore, the delay must take place in order to reach the passage time D at the correct time in which the door leaf 10 is held as far as possible in the opening position.

    [0034] Both cases according to FIGS. 3 and 4 show ways of interacting which is attributable solely to the behavior of the person 11 who passes the door system 100. In this respect, a haptic interaction between the person 11 and the door leaf 10 does not necessarily have to take place and a behavior of a person 11 can also be detected by the sensor unit from which an optimization of the actuation of the movement of the door leaf 10 can be derived.

    [0035] FIG. 5 lastly shows a structure of a door system 100 with a door actuator 1 which is operatively connected to a door leaf 10. The operative connection comprises a sensor 15 or the sensor 15 is coupled to the operative connection and can detect whether external forces are applied to the door leaf 10, for example if a person pushes a door leaf or pulls it back to the closure position. The information from the sensor 15 can be transmitted to the control unit 13 which ultimately comprises a correction value memory 14. Therefore, the actuation of the drive unit 16 can be continuously optimized via the control unit 13 and the correction values stored in the correction value memory 14 in order to continuously improve the behavior of the door leaf 10 for the specified point of use. In this case, the control unit 13 receives additional information from the sensor unit 12 which is by way of example designed as a radar sensor and serves to detect the people 11.

    [0036] The design of the disclosure is not restricted to the preferred exemplary embodiment indicated above. In fact, a number of variants is conceivable which make use of the solution represented even in the case of essentially different embodiments. All features and/or advantages emerging from the claims, the description or the drawings, including constructive details or spatial arrangements, may be essential to the disclosure by themselves and in the most varied combinations.
