Device and method for operating a closing part, driven by a drive, on a device of transportation

1. A device for operating a closing part, driven by a drive, on a device of transportation, the device comprising:

a control apparatus associated with the drive and configured to actuate the drive to initiate a measure which is opposed to a movement of the closing part, the drive being selected from the group consisting of an electric drive and an electromechanical drive, the drive being actuated by said control apparatus such that the drive becomes active in a braking fashion with respect to the movement of the closing part;

a decision device assigned to the control apparatus, which decides, on a basis of predefined decision criteria, whether the drive will become active in a braking fashion;

a sensor system for detecting at least one of a spatial position and a direction of movement of the closing part; and

a plausibility-checking device for checking a plausibility of output signals supplied by said sensor system, and a decision as to whether the drive will become active in a braking fashion being taken with consideration of a plausibility-checking result.

2. The device according to claim 1 , further comprising a short-circuit-generating device with which a short-circuit, which ultimately gives rise to a braking effectiveness of the drive, can be generated at the drive.

3. The device according to claim 2 , wherein the short-circuit can be generated between terminals of the drive.

4. The device according to claim 1 ,

wherein said control apparatus is configured to actuate the drive in dependence on a setpoint movement sequence plan which is stored in said control apparatus;

further comprising a determining apparatus configured to determine a deviation of an actual movement sequence of the closing part from a setpoint movement sequence; and

wherein said control apparatus is configured to cause the drive to become active in a braking fashion when the deviation is determined.

5. The device according to claim 1 , further comprising a warning apparatus with which a warning signal can be output after a decision that the drive will become active in a braking fashion.

6. A method for operating a closing part, driven by a drive, on a device of transportation,

providing a device having a control apparatus which is assigned to the drive and is configured to actuate the drive to initiate a measure which is opposed to a movement of the closing part, and the drive is selected from the group consisting of an electric drive and an electromechanical drive, the control apparatus has a decision device which decides, on a basis of predefined decision criteria, whether the drive will become active in a braking fashion;

actuating the drive via the control apparatus such that the drive becomes active in a braking fashion with respect to the movement of the closing part;

making available a sensor system for detecting at least one of a spatial position and a direction of movement of the closing part; and

providing a plausibility-checking device used for checking a plausibility of output signals which are supplied by the sensor system, and the decision as to whether the drive will become active in a braking fashion being taken with consideration of a plausibility-checking result.

7. The method according to claim 6 , which further comprises providing a short-circuit-generating device with which a short-circuit, which ultimately brings about a braking effectiveness of the drive, is generated at the drive.

8. The method according to claim 7 , which further comprises generating the short-circuit between terminals of the drive.

9. The method according to claim 6 , which further comprises:

configuring the control apparatus to actuate the drive in dependence on a setpoint movement sequence plan which is stored in the control unit;

providing the device with a determining apparatus configured to determine a deviation of an actual movement sequence of the closing pan from the setpoint movement sequence; and

configuring the control apparatus to cause the drive to become active in a braking fashion when the deviation is determined with respect to the movement of the closing part.

10. The method according to claim 6 , wherein the device has a warning apparatus with which a warning signal is output after the decision that the drive will become active in a braking fashion.
