Assembly group for adjusting an adjustment element relative to a stationary section of a vehicle

An assembly for adjusting an adjustment element relative to a stationary section of a vehicle, the assembly comprising:

• a drive motor for electromotively adjusting the adjustment element,
• an electrically actuatable coupling device which includes a coupling element for coupling the drive motor to a transmission element for adjusting the adjustment element, wherein in a slip state of the coupling device a slip exists between the coupling element and a further coupling element or the transmission element,
• a sensor device for measuring an acceleration value of the adjustment element during an adjustment of the adjustment element, and
• a control device for controlling the drive motor and the coupling device, wherein the control device is configured to calculate a force value or torque value acting on the coupling device with reference to the acceleration value obtained via the sensor device during an adjustment of the adjustment element in the slip state of the coupling device.
