Method and device for operating a head-up display for a vehicle

A method of operating a head-up display of a vehicle, the head-up display having a predefined display field, the method comprising the acts of:

• providing predefined route data for a driving route situated in front of the vehicle in a driving direction;
• providing at least one predefined predictive operating variable for the vehicle;
• determining a three-dimensional model for a predefined environment of the vehicle as a function of the provided predefined route data;
• determining a graphic element as a function of the three-dimensional model and the predefined predictive operating variable;
• displaying the determined graphic element in the predefined display field, wherein the graphic element is, from a predefined viewing position, perceived by a viewer of the display field as an enhanced feature of an actual environment of the vehicle;
• providing a predefined position of at least one predefined object;
• as a function of the provided predefined position and the determined three-dimensional model, determining an additional graphic element;
• and
• displaying the additional graphic element in the predefined display field, wherein the additional graphic element is, from the predefined viewing position, perceived by the viewer of the display field with direct reference to the actual environment of the vehicle.

A device for operating a head-up display of a vehicle, the head-up display having a predefined display field, the device comprising:

• a control unit configured to receive predefined route data for a driving route situated in front of the vehicle in a driving direction, at least one predefined predictive operating variable for the vehicle, and a three-dimensional model determined for a predefined environment of the vehicle as a function of the provided route data;
• and
• wherein the control unit is operatively configured to execute a program to:
• determine a graphic element as a function of the three-dimensional model and the predefined predictive operating variable;
• display the determined graphic element in the predefined display field, wherein the graphic element is, from a predefined viewing position, perceived by a viewer of the display field as an enhanced feature of an actual environment of the vehicle;
• acquire a control signal generated in response to the displaying of the graphic element in the predefined display field, said control signal being representative of a predefined actuation of an operating element in an interior of the vehicle;
• as a function of the acquired control signal and the determined three-dimensional model, determine a second graphic element;
• and
• display the second graphic element in the predefined display field, wherein the second graphic element is, from the predefined viewing position, perceived by the viewer with direct reference to the actual environment of the vehicle.
