Abstract

Official abstract text for this publication.

A vehicle door assembly including a vehicle door pivotally arranged on a vehicle body, a force-transmitting device for adjusting and/or fixing the vehicle door relative to the vehicle body, wherein the force-transmitting device includes a transmission element for producing a flux of force between the vehicle door and the vehicle body in order to adjust the vehicle door relative to the vehicle body or hold it in position relative to the vehicle body, and a control device for controlling the force-transmitting device. In addition, there is provided a sensor device in the form of an acceleration sensor arranged on the vehicle door for measuring the acceleration of the vehicle door, or a gyrosensor arranged on the vehicle door for measuring the angular velocity of the vehicle door, or a force sensor arranged in the flux of force between the vehicle door and the vehicle body.

First claim

Opening claim text (preview).

The invention claimed is: 1. A vehicle door assembly, comprising: a vehicle door pivotally arranged on a vehicle body; a force-transmitting device configured to adjust and selectively fix the vehicle door relative to the vehicle body, wherein the force-transmitting device includes, a transmission element, configured to establish a flux of force between the vehicle door and the vehicle body in order to adjust the vehicle door relative to the vehicle body or hold it in position relative to the vehicle body, and a drive shaft coupled to the transmission element and including at least one magnetic portion; at least one sensor device including a force sensor arranged in the flux of force between the vehicle door and the vehicle body and configured to measure a magnetic field produced by the at least one magnetic portion of the drive shaft, wherein the magnetic field is indicative of torsion applied to driveshaft; and a control device for controlling the force-transmitting device and configured to evaluate a sensor signal of the at least one sensor device to identify a user command for adjusting the vehicle door, wherein the control device is further configured to actuate the force-transmitting device based on the evaluation to enable adjustment of the vehicle door. 2. The vehicle door assembly of claim 1 , wherein the force-transmitting device includes an electrically actuatable coupling device which in a coupling, first condition couples a drive motor to the transmission element in order to exert an adjusting force for adjusting the vehicle door on the transmission element, and in a decoupling, second condition decouples the drive motor from the transmission element. 3. The vehicle door assembly of claim 2 , wherein in a holding position of the vehicle door the coupling device is in the coupling, first condition in order to fix the vehicle door relative to the vehicle body. 4. The vehicle door assembly of claim 3 , wherein the control device is configured to actuate the coupling device upon recognition of user's wish for adjustment for transferring from the coupling, first condition into the decoupling, second condition. 5. The vehicle door assembly of claim 1 , wherein the force-transmitting device includes a drive motor for electromotively adjusting the vehicle door, wherein the control device is configured to actuate the drive motor upon recognition of a user's wish for adjustment for electromotively adjusting the vehicle door. 6. The vehicle door assembly of claim 5 , wherein the drive motor is stationarily arranged on the vehicle door and the transmission element is articulated to the vehicle body. 7. The vehicle door assembly of claim 1 , wherein the drive shaft is coupled to the transmission element via a flexible coupling element configured for the transmission of tensile forces. 8. The vehicle door assembly of claim 7 , wherein a sensor device in the form of a force sensor is arranged on the transmission element for measuring a force on the coupling element. 9. The vehicle door assembly of claim 8 , wherein the sensor device in the form of the force sensor is arranged on a tensioning device for tensioning the coupling element relative to the transmission element. 10. A vehicle door assembly comprising: a vehicle door pivotally arranged on a vehicle body; a force-transmitting device configured to adjust and selectively fix the vehicle door relative to the vehicle body, wherein the force-transmitting device includes, a stationary portion, and a transmission element configured to establish a flux of force between the vehicle door and the vehicle body in order to adjust the vehicle door relative to the vehicle body or hold it in position relative to the vehicle body; at least one sensor device including a force sensor arranged in the flux of force between the vehicle door and the vehicle body and configured to measure deformation of the stationary portion; and a control device for controlling the force-transmitting device and configured to evaluate a sensor signal of the at least one sensor device for identifying a user command for adjusting the vehicle door, wherein the control device is further configured to actuate the force-transmitting device based on the evaluation to enable adjustment of the vehicle door. 11. The vehicle door assembly of claim 10 , wherein the force sensor is disposed on the stationary portion. 12. The vehicle door assembly of claim 10 , wherein the force sensor is an inductive sensor or as a piezosensor.
