Abstract

A device for controlling a driven moving element including an electronic unit with an object sensor. According to the invention, the electronic unit is designed, by means of the object sensor, to determine an object distance between the driven moving element and an object in the region of the moving element and to control the movement of the moving element depending on said object distance.

Claims

1. A device for controlling a driven moving element comprising an electronic unit with an object sensor, wherein the electronic unit is designed, by means of the object sensor, to determine an object distance between the driven moving element and an object in the region of the moving element and to control the movement of the moving element depending on said object distance, wherein the electronic unit is furthermore designed to use a front edge of the moving element as reference at the moving element for determining the object distance.

2. The device as claimed in claim 1, wherein means are provided to determine the object distance from a distance between the object sensor and the object, a distance between the object sensor and the moving element and the angle α

between the distance directions.

3. The device as claimed in claim 1, wherein the object sensor comprises a transmitter and receiver for a signal, e.g. for sound or electromagnetic waves, in particular light, wherein the electronic unit is designed to determine a distance which a signal emitted by the transmitter covers via a reflection surface to the receiver, by an evaluation of a signal profile, e.g. in the case of light, of a phase of an oscillation modulated onto the light, and to determine the object distance with this type of distance measurement.

4. The device as claimed in claim 1, wherein the electronic unit generates a control signal for the control of the driven moving element depending on the velocity (V₀) of the object and/or the velocity (V_l, V_r) of the driven moving element.

5. The device as claimed in claim 1, wherein the electronic unit performs the control of the driven moving element in such a way that the object distance between a location of the driven moving element, preferably the front edge of the driven moving element, and the object is kept at a predetermined value.

6. The device as claimed in claim 1, wherein a plurality of driven moving elements can be controlled independently.

7. The device as claimed in claim 1, wherein a plurality of driven moving elements cannot be moved independently, the smallest distance determined is crucial for the control of the moving elements.

8. The device as claimed in claim 1, wherein the electronic unit generates a control signal for the control of the driven moving element which takes account of a deceleration distance of the driven moving element.

9. The device as claimed in claim 1, wherein the electronic unit controls the driven moving element in such a way that the moving element is closed as rapidly as possible after an object has passed the moving element, and/or that the moving element is opened as late as possible when an object moves toward the moving element.

10. The device as claimed in claim 1, wherein the electronic unit controls the velocity of the moving element to an inherently undisturbed movement path depending on the object distance.
