Method and device for operating a head-up display for a vehicle
First Claim
1. 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; and
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 with direct reference to an actual environment of the vehicle;
acquiring 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; and
as a function of the acquired control signal and the determined three-dimensional model, determining a second graphic element; and
displaying 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.

Abstract
Predefined route data for a driving route situated in front of the vehicle in the driving direction are provided. Further, at least one predefined predictive operating variable for the vehicle is provided. A three-dimensional model for a predefined environment of the vehicle is determined as a function of the route data. A graphic element is determined as a function of the three-dimensional model and of the at least one predictive operating variable. A head-up display of the vehicle has a predefined display field. The graphic element is displayed in the predefined display field. The graphic element is determined and displayed such that the graphic element is perceived by a viewer of the display field from a predefined viewing position with direct reference to the real environment of the vehicle.
