[0035] FIG. 4 a method for operating a door system with the method carried out according to the disclosure.

DETAILED DESCRIPTION OF THE DRAWINGS

[0036] FIG. 1 shows, in a side view, a door system 100 having a door leaf 10, which is arranged in a wall 15 so as to be rotatable. To actuate the door leaf 10, a door drive 16 is used, which has a control unit 14, and the control unit 14 does not have to be a structural component of the door drive 16, and the control unit 14 can also be arranged separately. The door drive 16 can open and close the door leaf 10, with the door leaf 10 being represented closed in the arrangement shown.

[0037] On a first door side A, a first sensor unit 11 is used to monitor a first distant area F and on the second door side B, a second sensor unit 12 is used to monitor a second distant area F. The near areas N adjoining the door system 100 can, but must not necessarily, be monitored by the sensor units 11, 12 which are preferably designed as radar sensors. The near areas N can be monitored by optical sensors or by ultrasound sensors, in particular incorporating closure edge monitoring.

[0038] In the image shown, a person 13 is drawn in multiple times, who moves towards the door system 100 from left to right on the first door side A and the person 13 shown moves away from the door system 100 on the second door side B.

[0039] If the person 13 now moves towards the door system 100 on the first door side A, then the first sensor unit 11 designed as a radar sensor detects the person 13 and a probable approach time ETA is determined from the distance and the approach speed of the person relative to the door system 100. The probable approach time ETA is the time which the person 13 requires, from the position shown, to cross the door system 100 and the probable approach time ETA is calculated with the control unit 14.

[0040] The person 13 shown on the second door side B is detected by the second sensor unit 12 and an exit time ETD is determined with the recording of the distance of the person 13 and the exit speed from the door system 100.

[0041] The method according to the disclosure is carried out with at least the following steps: determining a probable approach time ETA of the person 13 after which the person 13 passes through the door system 100 after being first detected; opening the door leaf 10; storing the approach time ETA; recording an exit time ETD of the person 13 from the second door side B by means of the second sensor unit 12 and holding open the door leaf 10 for an opening period which is determined from the recorded exit time ETD or the approach speed ETA, depending on which time is longer.

[0042] The comparison of the exit time ETD with the approach time ETA takes place in the control unit 14, which, for this purpose, has a comparison module to compare the times.

[0043] FIG. 2 shows a plan view of a door system 100 which is arranged in the opening of a wall 15. The door system 100 has a pivotable door leaf 10 in a manner known per se which is shown in an open position. A first sensor unit 11 is located above the passage region through the wall 15 and the first sensor 11 monitors the first door side A. For the sake of simplicity, a second sensor unit on the second door side B is not shown, but it is present.

[0044] The person 13 approaches the door system 100 according to this example not from the orthogonal direction drawn in, but rather at an approach angle α. The approach angle α is also monitored by the first sensor unit 11 and the approach time ETA can also be determined here taking into account the approach angle α.

[0045] FIG. 3 and FIG. 4 each show a schematic sequence of the method steps, with FIG. 3 reflecting the state of the art and FIG. 4 has, superimposed on the view of the state of the art, the features of the disclosure about which detail will be given later.

[0046] The method step 110 in FIGS. 3 and 4 designates the detected status of the door system as being closed. The detected status “closed” 110 precedes the method according to the disclosure as the first method step.

[0047] A second method step 111 follows the approach of the person which is detected by the first sensor unit. This is followed by the method step 112 or the determination of the approach time ETA and the determined approach time ETA is used in the method step 113 for the opening algorithm.

[0048] Then, the person passes the door system 100 according to method step 114 and in method step 115, the second sensor unit is used to measure the distance and the exit speed. In step 116, the exit time ETD is determined from the values of step 115 in order to provide a closing criterion to close the door leaf. Lastly, in method step 117, the close command is emitted to close the door leaf.

[0049] According to FIG. 4, the further method step 118 is indicated which relates to the immediate storage and provision of the approach time ETA, which follows from step 112. The value of the approach time ETA is then reused in method step 116 with the exit time ETD being determined. To this end, the comparison module 17 is provided in the control unit with which the approach time ETA and the exit time ETD are compared. Depending on which time is longer, i.e. which causes the door leaf 10 to close later, the method step 117 will be carried out to close the door leaf after the later time.

[0050] 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.
