Abstract
A method for operating a motor vehicle drive train device for a motor vehicle, which includes a motor, connected at least temporarily to at least one wheel of the motor vehicle via a torque transmission assembly, and a park lock device. The park lock device form-fittingly fixes a locking element coupled in a rotationally fixed manner to the torque transmission assembly in a first setting and releases in a second setting and, when the park lock device is switched from the first setting to the second setting, a compensating torque is generated on the locking element by the motor, which compensating torque counteracts a tensioning torque by a tensioning of the torque transmission assembly when the locking element is fixed. The compensating torque is determined from a torsional angle of the torque transmission assembly determined after fixing of the locking element and a torsional stiffness of the torque transmission assembly.
