A vibration damper for a tubular propeller shaft in the drive train of a motor vehicle having a mass body mounted concentrically, in the propeller shaft or in a sleeve attached in the propeller shaft, by way of at least one rubber spring element. Metal and/or flexible rubber stop elements that limit the vibration travel of the mass body at least in the radial direction are arranged between the mass body and the sleeve. Alternatively, the mass body and/or the sleeve are configured at least locally, in mutually opposite regions, as stop elements that limit the vibration travel of the mass body at least in the radial direction.

Vibration damper for a tubular drive shaft

In a method for operating a motor vehicle having an automatic transmission in the time of a selection action for a driving-mode range, first a driver's requirement for a change in the driving-mode range is transferred to a selection device, a change signal is then generated by the selection device, the change signal is subsequently transferred to a control unit, and, finally, a change in the driving-mode range of the automatic transmission is brought about by the control unit according to the change signal. In the time of the selection action for the driving-mode range, at least one braking device is actuated in an automated manner by the or a control unit. Drive-train oscillations may be reduced or avoided by the method.
