<p>A device for automatically controlling the operation of a door (10) with a vertically adjustable door leaf (14) detects the presence of an object (22) moving towards the door (10) to pass therethrough. In response to this detection, the door (10) is opened. A first sensor means (24) detects the height (H) of the object (22) approaching the door (10) and emits a first signal (S1) representing the detected height (H) of the object (22). A second sensor means (34) responds to the opening movement of the door leaf (14) by continuously emitting a second signal (S2) representing the current degree of opening (h) of the door leaf (14). A signal-processing means (32) receives the first signal (S1) and the second signal (S2) to compare the detected height (H) with the current degree of opening (h) of the door leaf and, in response to the result of this comparison, steplessly guides the door leaf (14) towards a stop position in which its degree of opening (h) corresponds to the detected height (H) of the object (22).</p> |
