Abstract
A method for operating a control device for a transportation vehicle to assist a driver maneuvering the transportation vehicle up to a trailer to couple the transportation vehicle to the trailer, wherein target coordinates of a coupling position provided for the transportation vehicle for coupling are determined by the control device and the process repeated, while a graphical distance display element is displayed to the driver by a display apparatus, a current distance value of a distance of the transportation vehicle from the coupling position is determined, and a size parameter of the graphical distance display element is adjusted based on the current distance value. A non-linear scaling function brings about a higher position resolution in a near region around the coupling position than outside the near region is used for a conversion from the respectively current distance value into a value of the size parameter.
