1. A method for operating an automatic door system with at least one movable, adjustable and/or pivotable door leaf, whereby an immediate door opening region with a door width can be cleared as well as closed, the automatic door system further comprising a control and evaluation device; and a sensor device, wherein the sensor device implements a monitoring region assigned to or disposed upstream of the leaves and wherein the sensor device detects objects which are situated within or moving into the monitoring region, the method comprising the steps of:
detecting by means of the sensor device or the control and evaluation device, an object or an object group situated in the monitoring region, wherein a position and direction of movement thereof are determined and wherein a width, size or contour or overall contour thereof is determined,
calculating a safety and/or side spacing, wherein the safety and/or side spacing is determined based on at least one additional parameter, wherein the additional parameter includes one or more of a temperature, an energy consumption, a temperature difference between spaces separated from one another by the automatic door system, an object class, an object orientation, and a collision risk;
determining by the control and evaluation device an opening width of the at least one door leaf as a function of time, wherein the opening width depends on a current position and direction of movement of the detected object and the safety and/or side spacing, wherein a cross section of the object in the immediate door opening region is determined by the width, size and/or contour or overall contour and the current position of the detected object with respect to door opening region of the detected object plus the safety and/or side spacing, wherein the opening width changes as the current position changes during the progressive movement of the detected object through the door region,
performing an opening of the at least one door leaf wherein the at least one door leaf is moved increasingly further in an opening direction so that the opening width varies with the cross section of the object at the current position passing through the immediate door opening region, and wherein the opening movement of the at least one door leaf first ends when the current position of the detected object is situated at least partially in the immediate door opening region of the at least one door leaf,
and
performing a closing of the at least one door leaf, wherein the at least one door leaf is moved increasingly further in a closing direction, so that the opening width varies with the cross section of the object at the current position passing through the immediate door opening region and wherein the closing movement of the at least one leaf starts when the current position of the detected object is still at least partially situated in the immediate door opening region of the at least one door leaf.
