Method for operating an operating device for a transportation vehicle to assist a driver when coupling the transportation vehicle to a trailer, operating device, and transportation vehicle

A transportation vehicle comprising a control device with a computing apparatus to carry out 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 and repeated by the control device, 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 predetermined size parameter of the graphical distance display element is adjusted based on the current distance value,

• wherein a non-linear scaling function which brings about a higher position resolution at least in a predetermined near region around the coupling position than outside the respective near region is used for a conversion from the respectively determined current distance value into a value of the size parameter that is to be set.
