[0031] FIG. 2 a flow diagram, which represents the method according to the disclosure.

DETAILED DESCRIPTION OF THE DRAWINGS

[0032] FIG. 1 shows the view of a door system with a door actuator 1 for actuating a door leaf 10. A control device 11 is shown as part of the door actuator 1, which is mounted on the upper side of the door. Sensor units 12 located on both sides of the door system are used to detect the three people 13, 14 and 15 shown by way of example. The people 13, 14 and 15 approach the door leaf 10 with the person vectors V1, V2 and V3 for example from both sides of the door system.

[0033] FIG. 2 presents the method according to the disclosure for operating the door actuator 1 on the basis of a simplified flow diagram. First, the method proceeds from the detection of at least one first person and, if a plurality of people are detected, calculated control parameters are compared. The reference numerals from FIG. 1 can be used accordingly for the following description.

[0034] First, a first person 13 is detected, with this step being labeled with 100. Then, the step 110 follows relating to a calculation of the probable arrival time of the first person 13 at the door leaf 10. The arrival time can be calculated from a person vector V1, with the person vectors V1, V2 and V3 being determined in step 110. The person vector V1 is at least determined from a speed of the detected person 13, which represents the vector length, and is determined from a movement direction of the detected person 13, which represents the vector direction.

[0035] Then, the calculation of first control parameters 16′ follows in step 120, for example shown saved in the index memory 17 and the first control parameters 16′ are used to actuate the door leaf 10 in relation to the first person 13 or based on a first person vector V1, if this is calculated from the first control parameters 16′. The first control parameters 16′ are then stored in the index memory 17 as shown, with the control parameters 16, in particular an opening time, an opening speed and an opening hold period of the door leaf 10, being saved in or by step 130.

[0036] Saving the control parameters 16′ in step 130 is followed by step 140 which relates to a query as to whether a control parameter set 16′ of a previously detected person is already stored in the index memory 17. If a control parameter set 16′ is not stored, the detected person 13 is thus the first person, the activation 190 of the door actuator 1 ultimately takes place with the opening time query 200, if the latest time for activating the opening movement of the door leaf 10 is reached.

[0037] However, if it is determined in the query 140 that a control parameter set 16′ is already stored in the index memory 17 and another person 14 is detected, then a comparison 150 is activated with the further determination of control parameters 16″ via the steps 110, 120 and 130, in which first control parameters 16′ are compared with second control parameters 16″ or a first control parameter set 16s1 from the index memory 17 and third control parameters 16″′ or a second control parameter set 16s2 are compared with one another. This method step 150 is followed by a tolerance query 170 and if the deviation of the parameters, as compared with one another above, is within a tolerance, the further opening time query 200 takes place such that an activation 190 of the door actuator 1 ultimately takes place on the basis of one of the control parameters 16′ or 16″ or control parameter set 16s1 or 16s2.

[0038] If the deviation of the parameters, as compared above, is not within the tolerance, only then is a control parameter set 16s1 formed and if no further person 15 is detected, then the activation 190 of the door actuator 1 and the opening time query 200 is carried out on the basis of the first control parameter set 16s1.

[0039] The generated control parameter set 16s1 or 16s2 results from the value integration 180, which takes place after the tolerance query 170, if the deviations between the parameters to be compared are not within the tolerance, labeled with “no”. The generated control parameter set 16s1 or 16s2 then forms the new index 1 or 2 to be stored in the index memory 17 such that the new index is formed 210 in the index memory 17 by saving 130 the control parameters.

[0040] As a result, an optimal actuation of the door leaf 10 is generated and, after the value integration 180 and the re-indexing of the memory 17, a reset 160 of the index memory 17 again lastly takes place and the control device 11 of the door actuator 1 is for example reset to a standby mode.

[0041] 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 emerging from the claims, the description or the drawings and/or also any indicated advantages, including constructive details or spatial arrangements, may be essential to the disclosure by themselves and in the most varied combinations.
