[0030] Further measures that improve the disclosure will be outlined in greater detail below together with the description of a preferred exemplary embodiment of the disclosure on the basis of the figures, which show:

[0032] FIG. 2 a door system in a plan view with a plurality of people who pass through the sensor detection region from respective directions, and

DETAILED DESCRIPTION OF THE DRAWINGS

[0034] FIG. 1 shows the door system 100 with a door actuator 1 and a movable door leaf 10 which is operatively connected to the door actuator 1 and can be pivoted with the same. The door system 100 also has a sensor unit 12, which is connected to a control device 11, with the control device 11 for example being part of the door actuator 1 or being designed so as to form a structural unit with the same.

[0035] The sensor unit 12 can cover a sensor detection region 15 in a region before the door system 100, and when a person 13 passes through the sensor detection region 15, the sensor unit 12 designed in particular as a radar sensor can record the speed S and the approach angle α of the person 13 at which the person 13 moves laterally towards the door system 100. The movement vector V is formed from the speed S and the approach angle α, with the speed S being represented by the length of the movement vector V. If the person 13 approaches the door system 100 from one side and the angle α at 0° represents an orthogonal direction perpendicular to the closed door leaf 10, then the angle α will be for example greater than 45° when the person 13 approaches laterally. If the person 13 approaches the door system 100 at the approach angle α=90°, then the person 13 moves parallel along the wall 16 in which the door system 100 is installed.

[0036] FIG. 2 shows a plan view of the door system 100 with the door actuator 1, the door leaf 10 and the control device 11 and a sensor unit 12 is shown which can cover the sensor detection region 15. Four people 13 are also shown who approach the sensor detection region 15 from different directions.

[0037] The movement vectors V1 to V4 have, in relation to FIG. 1, different approach angles α with an angle position according to FIG. 1 such that it can be detected from the length of the movement vectors V1 to V4 in conjunction with the approach angle α whether or not a person 13 has a desire to enter the door system 100.

[0038] The person 13, who enters the sensor detection region 15 with the movement vector V1, has, in this case probably with higher probability, an intention to enter than the person 13, who approaches the sensor detection region 15 with the movement vector V3 and crosses through it. The same applies to the tangentially running movement vector V2, which in this respect represents a simple cross movement, whereas the movement vector V4 represents a clear intention to enter and pass the door system 100.

[0039] The method according to the disclosure is represented in the form of a diagram in FIG. 3. In this case, the method provides for the following steps proceeding from the condition 105 of a closed door leaf: detecting 110 a person 13 approaching the door system 100 laterally, identifying 120 a parameter set P comprising the distance A changing in time, the approach angle α and/or the speed S of the person 13 relative to the door system 100 and determining 130 the desire to enter of the person approaching laterally on the basis of a comparison of the currently identified parameters with stored parameter sets P1, P2, P3 to which a desire to enter is assigned and stored. The comparison takes place in this case such that a parameter set P1, P2, P3 that is as similar as possible is identified in the memory and the desire to enter stored with the similar parameter set P1, P2, P3 forms the basis of the new evaluation of the current parameter set. It is assumed for the evaluation that if, when the older, stored parameter set P1, P2, P3 was recorded, the person in turn passed the door system, the person 13 or another person will do the same again on the next approach with the same or similar parameters and will pass the door system.

[0040] In the step of determining 130, there is the possibility that the desire to enter is confirmed, represented with a plus sign, such that ultimately the step 140 of opening the door leaf follows in the case of the determined desire to enter. If the determination 130 is negative such that there is no desire to enter, represented by a minus sign, then step 150 follows according to which the door leaf remains closed.

[0041] In this case, between the step 120, according to which the parameter set P is identified, and determining the desire to enter 130, the parameter sets P can be exchanged with a memory 14, with the memory 14 for example being part of the control device 11. The parameter sets P1, P2, P3 linked with the respectively actually determined desire to enter can be stored in the memory 14, with it also being conceivable that the memory 14 can contain pre-stored parameters P, which are represented by a plurality of parameter sets P1, P2, P3, etc. The newly added parameter sets P in conjunction with the determined desires to enter can in this case be included with the pre-stored parameter sets P1, P2, P3, etc., and the parameter sets P can also be correlated with one another.

[0042] 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.
