Abstract
The invention relates to a motor vehicle door comprising a door leaf with a drive, a magnetic device as a component of the drive, and at least one sensor which is associated with the door leaf. According to the invention, said magnetic device also comprises a magnetorheological element and/or a magnetohydrodynamic element which can be actuated by at least one magnet.
Claims19
Motor vehicle door comprising a door leaf with a magnetic device and a hinge shaft that pivotally couples the door leaf to a motor vehicle, the magnetic device containing at least one magnet and a magnetorheological element, arranged around and acting on the hinge shaft, which is provided as a damping element allowing adjustable damping and can be actuated by the at least one magnet with the magnetorheological element, at least one sensor assigned to the door leaf for transmitting a door position via sensor signals, wherein the at least one sensor and the at least one magnet are connected to a control unit, said control unit actuating the magnet depending on the sensor signals, wherein the magnet varies a damping of the magnetorheological element depending on an acceleration of the door leaf as monitored by the at least one sensor, and wherein the control unit actuates the magnet and varies the damping depending on an external temperature monitored by the at least one sensor.
Method for actuating a door leaf of a motor vehicle door, wherein actuating the door leaf includes one or more actions from the group consisting of braking, fixing, closing and opening the door leaf, in which the motor vehicle door contains the door leaf, a hinge shaft that pivotally couples the door leaf to the motor vehicle and a magnetic device containing at least one magnet and a magnetorheological element, arranged around the hinge shaft, which is provided as a damping element allowing adjustable damping and can be actuated by the at least one magnet, at least one sensor assigned to the door leaf for transmitting a door position via sensor signals, in which the at least one sensor determines individual functional states of the door leaf in relation to the motor vehicle body and transmits them to a control unit and in which the control unit energizes the magnetic device containing the magnetorheological element and actuatable by the magnet in such a way that the door leaf is either stopped, retained or closed, opened or pushed out, the method further comprising actuating the magnet thereby varying the damping of the magnetic device depending on an external temperature monitored by the at least one sensor.
Motor vehicle door comprising a door leaf with a magnetic device and a hinge shaft that pivotally couples the door leaf to a motor vehicle, the magnetic device containing at least one magnet and a magnetorheological element, arranged around and acting on the hinge shaft, which is provided as a damping element allowing adjustable damping and can be actuated by the at least one magnet with the magnetorheological element, at least one sensor assigned to the door leaf for transmitting a door position via sensor signals, wherein the at least one sensor and the at least one magnet are connected to a control unit, said control unit actuating the magnet depending on the sensor signals, wherein the magnet varies a damping of the magnetorheological element depending on a speed of the door leaf as monitored by the at least one sensor, and wherein the control unit actuates the magnet and varies the damping depending an external temperature monitored by the at least one sensor.
