DETAILED DESCRIPTION OF THE DRAWINGS

[0039] FIGS. 1 and 2 each show a door system 100 with a door leaf 10 which can be swiveled by means of a door actuator 1. The door leaf 10 has a hinge side for this purpose which is represented on the left side of the door leaf 10 and forms the pivot point of the door leaf and the free side of the door leaf 10 forms the closure side which has a fitting of the door leaf 10 in a manner not shown in more detail. FIG. 1 shows here the door leaf 10 with a first opening width I, which is for example 75°, and FIG. 2 shows the door leaf 10 in a second opening width II, which is for example 45°. The door leaf 10 is located in the closed position, consequently in a 0° position.

[0040] FIG. 1 shows a person 13 who moves perpendicularly towards the door system 100. This perpendicular position forms an approach angle of 0°, whereas in FIG. 2 the person 13 is shown who approaches the door system at an approach angle α, for example at 30°.

[0041] The comparison of the FIGS. 1 and 2 shows that, in the case of a person 13 approaching obliquely from the hinge side, the door leaf 10 does not open as wide as in the case of a person 13 approaching the door system 100 perpendicularly, i.e. from the direction of 0°. The method for carrying out the disclosure provides in this case that the approach angle α of the person 13 is detected using a sensor unit 11 and the approach angle α forms the angle of the person 13 to the perpendicular direction of 0°, at which the person 13 moves obliquely towards the door system, the method also provides that the door leaf 10 opens either at the first opening width I or at the second opening width II, which depends on the detected approach angle α. Additionally, a first or second opening speed can be provided when opening the door leaf 10, and, in the case of a greater first opening width I, the opening speed results with a greater value than in the case of a smaller second opening width II.

[0042] FIGS. 3 and 4 each show door systems 100 with door leaves 10 configured to move in a sliding manner and the movement of the door leaves 10 is controlled via the control unit 12. The sensor unit 11 is for example shown only on an approach side of the door system 100, it can also be present in an identical manner on the exit side of the door system 100.

[0043] In FIG. 3, the person 13 approaches from the perpendicular of the door system 100, reflected with the angle 0° and the two door leaves 10 open along the same path and at the same speed.

[0044] In FIG. 4, the person 13 approaches at the angle α to the perpendicular at 0° and the example shows that the door leaf 10 is opened further on the approach side of the person 13 than the door leaf 10 on the side facing away from the approach side. In this case, the door leaf 10 on the left side facing away from the approach can still of course open by a certain distance and the door leaf 10 on the right side does not also have to open fully. The opening widths of both door leaves 10 ideally enable a passage section for the movement path of the person 13, as they walk through the door system 100. For example, the left door leaf 10 in this case presents the smaller first opening width I and the right door leaf the greater second opening width II.

[0045] The movement of the door leaves 10 is controlled via a control unit 12 which is electrically connected to the at least one sensor unit 11 in a manner not shown in more detail. The sensor unit 11 is for example a radar sensor or a camera, which allows not only the presence of the person 13 to be detected, but rather the sensor unit 11 can also detect the distance of the person 13 from the door system 100 as well as the angle α, at which the person 13 approaches the door system 100. Moreover, a radar sensor or a camera with a corresponding image evaluation system can determine the approach speed of the person 13.

[0046] FIG. 5 shows a door system 100 with a door actuator 1 for actuating a door leaf 10 and a sensor unit 11 is arranged on both sides of the door system 100. A detection region 14 can in each case be detected using the sensor unit 11 such that people 13 located inside the detection region 14 can be detected using the sensor units 11. An inner region 15, which cannot be monitored using the sensor units 11, is located between the two detection regions 14, in particular directly inside or below the door system 100 and the door leaf 10 respectively. The sensor units 11 are in this case configured such that a movement vector V can be determined, which results from an approach angle and the approach speed of the person 13 who approaches the door system 100. The movement vector V in this case forms the parameter for the opening widths I, II, at which the door leaf or door leaves 10 should be opened; similarly, the opening speed of the door leaf 10 can be determined on the basis of the parameter, based on the movement vector V. The movement vector V can in this case be formed beginning from the detection region 14 on the approach side up to the end of the detection region 14 on the exit side of the door system 100. The inner region 15, which cannot be detected using the sensor units 11, can also be determined by way of calculation. Consequently, a continuous, single movement vector V, which is calculated in real time for each section of the approach, can be determined from the two individual movement vectors V shown by way of example.

[0047] FIG. 6 shows a door arrangement 100 with a sensor unit 11 which is rotated in the direction towards a closure side of the door leaf 10. The sensor unit 11 is for example a radar sensor, which is fixedly arranged, and in this respect is no longer rotated during the permanent operation of the door system 100.

[0048] The sensor unit 11 designed as a radar sensor has a main detection region H, which, in the non-rotated arrangement, has a central axis of 0° orthogonal to the door system 100. This main detection region H extends for example from −50° to +50° around the 0°. If the sensor unit 11 rotates by a rotation angle β, then a rotated main detection region H′ also results. The then applicable 0° are drawn in with dashed lines with the two boundaries of the main detection region H′.

[0049] The regions which cannot be detected further with full field strength or are no longer detectable, in addition to the main detection region H′, are drawn in as a wide area Z1 and a narrow area Z2. If the sensor unit 11 were not rotated, both areas Z1 and Z2 would be the same size. However, the rotation results in a narrow area Z2 from the direction of the closure side of the door leaf 10, whereas, on the hinge side of the door leaf 10, the area spreads out such that a wider area Z1 results.

[0050] Since the narrow area Z2 has been reduced by the sensor unit 11 being rotated, people can then be detected in an improved manner when they approach the door system 100 from the narrow area Z2 or in the edge region to the adjoining main detection region H′. This results in the advantage of an improved function during the operation of the door system 100 such that people, who approach from the closure side, can be better detected. People, who approach the door system 100 from the hinge side, naturally preferably walk around the wide area Z1 since people know that the door has an opening direction which is counter to the direction of travel. In this respect, an enlargement of the wide area Z1 on the hinge side of the door leaf 10 is not necessarily disadvantageous. 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, including constructive details or spatial arrangements, which emerge from the claims, the description or the drawings, may be essential to the disclosure by themselves and in the most varied combinations.
