Method for controlling door movements of the door of a motor vehicle, and motor vehicle component

A method for controlling a door movement of a controllable door of a motor vehicle, wherein at least one control device and at least one sensor arrangement are associated with the door and wherein the door includes a controllable motion influencing device configured to at least partially control and influence a motion of a door wing of the door to alternate between a closed position and an open position, the motion influencing device including a driving device with a drive motor and a braking device, the method comprising:

• providing the sensor arrangement with a sensor configured to detect a measure of a rotational force required for a closing motion of the door;
• providing the braking device with:
• a first component equipped with a rotary takeup, a second component rotatably received on the rotary takeup, the second component being rotatable about a rotation axis, and a third component coupled to the second component;
• a first connector unit and a second connector unit that are movable relative to each other, the first connector unit being disposed on the first component and the second connector unit being pivotably coupled to the third component for rotation about a pivot axle;
• the first and second connector units being mounted to relatively moving the door, and the pivot axle extending transversely to the rotation axis of the second component;
• and
• wherein bearings are disposed between the rotary takeup and the second component, and wherein between the bearings electric coils are arranged in order to provide a magnetic field source to generate a magnetic field in order to create a braking momentum between the first component and the second component;
• and
• during a closing motion of the door wing, detecting an obstacle by the control device when the door wing is not yet closed, and the rotational force increases above a predetermined threshold;
• and
• when the obstacle is detected, stopping the drive motor with the control device by activating the braking device.

A motor vehicle component for controlling a door movement of a controllable door of a motor vehicle, comprising:

• a control device and a sensor arrangement;
• a controllable motion influencing device for controlling and influencing a motion of a door wing of the controllable door to alternate between a closed position and an open position;
• said motion influencing device including a driving device with a drive motor and a braking device, and said sensor arrangement including a current sensor for detecting a motor current of said drive motor;
• said braking device having:
• a first component equipped with a rotary takeup, a second component rotatably received on said rotary takeup, said second component being rotatable about a rotation axis, and a third component coupled to said second component;
• a first connector unit and a second connector unit that are movable relative to each other, said first connector unit being disposed on said first component and said second connector unit being pivotably coupled to said third component for rotation about a pivot axle;
• said first and second connector units being mounted to relatively moving the door, and said pivot axle extending transversely to said rotation axis of said second component;
• and
• wherein bearings are disposed between said rotary takeup and said second component, and wherein between said bearings electric coils are arranged in order to provide a magnetic field source to generate a magnetic field in order to create a braking momentum between said first component and said second component;
• and
• said control device being configured, at least while closing the door wing, to detect an obstacle, when the door wing is not yet closed and a power input of the drive motor rises above a predetermined threshold;
• and
• said control device being configured to stop the drive motor when the obstacle is detected and activate the braking device.
