Abstract

A dataset is determined as a function of a specified navigation information, where the dataset includes a specified metadata structure which is suitable for textually characterizing the navigation information. The dataset is transmitted by way of a specified communication interface. As a function of the dataset received by way of the communication interface, pixel values are determined for at least a portion of pixels of a digital image and/or of a graphic element. Furthermore, a signalization signal is determined for signalizing the pixel values of the pixels by means of the optical display device.

Claims

1. A method of operating an optical display device of a vehicle, wherein

a dataset is determined as a function of a specified navigation information, the dataset having a specified metadata structure which is suitable for textually characterizing the navigation information, wherein the dataset consists of only non-graphic text data,

the dataset is transmitted by way of a specified communication interface and, as a function of the dataset received by way of the communication interface, pixel values are determined for at least a portion of pixels of a digital image and/or a graphic element, and

a signalization signal is determined for signalizing the pixel values of the pixels by means of the optical display device.

2. The method according to claim 1, wherein the navigation information comprises a driving instruction for a vehicle user.

3. The method according to claim 1, wherein as a function of specified route data and/or specified environment data, a three-dimensional model is determined for a specified environment of the vehicle, and

the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element are determined as a function of the three-dimensional model.

4. The method according to claim 2, wherein as a function of specified route data and/or specified environment data, a three-dimensional model is determined for a specified environment of the vehicle, and

the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element are determined as a function of the three-dimensional model.

5. The method according to claim 3, wherein the optical display device comprises a head-up display with a specified display field, and

the pixel values of the graphic element are determined such as a function of the dataset and the three-dimensional model and are displayed on the display field that a viewer of the display field perceives the graphic element from a specified viewing position with a direct reference to the real environment of the vehicle.

6. The method according to claim 4, wherein the optical display device comprises a head-up display with a specified display field, and

the pixel values of the graphic element are determined such as a function of the dataset and the three-dimensional model and are displayed on the display field that a viewer of the display field perceives the graphic element from a specified viewing position with a direct reference to the real environment of the vehicle.

7. A data determination unit configured to:

determine a dataset as a function of a specified navigation information, the dataset having a metadata structure which is suitable for textually characterizing the navigation information, wherein the dataset consists of only non-graphic text data; and

send the dataset by way of a specified communication interface.

8. An image determination unit, which can be coupled with respect to signals with an optical display device of the vehicle, configured to:

receive a specified dataset which is transmitted by way of a specified communication interface, wherein the dataset consists of only non-graphic text data,

as a function of the received dataset, determine pixel values for at least a portion of pixels of a digital image and/or of a graphic element, and

determine a signalization signal for signalizing the pixel values of the pixels by means of the optical display device.

9. The image determination device according to claim 8, further configured to:

determine, as a function of specified route data and/or specified environment data, a three-dimensional model for a specified environment of the vehicle, and

determine the pixel values for the at least one portion of the pixels of the digital image and/or of the graphic element as a function of the three-dimensional model.

10. The image determination unit according to claim 9, wherein the optical display device comprises a head-up display with a specified display field, and wherein the image determination unit is configured to:

determine the pixel values of the graphic element as a function of the dataset and the three-dimensional model and causing them to be displayed on the specified display field of the head-up display such that a viewer of the display field will perceive the graphic element from a specified viewing position with direct reference to the real environment of the vehicle.

11. A display system for a vehicle comprising:

a data determination unit configured to determine a dataset as a function of a specified navigation information, the dataset having a metadata structure which is suitable for textually characterizing the navigation information, and further configured to send the dataset by way of a specified communication interface;

an image determination unit, which can be coupled with respect to signals with an optical display device of the vehicle, the image determination unit configured to;

receive a specified dataset which is transmitted by way of a specified communication interface, wherein the dataset consists of only non-graphic text data,

as a function of the received dataset, determine pixel values for at least a portion of pixels of a digital image and/or of a graphic element, and

determine a signalization signal for signalizing the pixel values of the pixels by means of the optical display device;

a specified communication interface which, with respect to signals, couples the data determination unit and the image determination unit; and

at least one optical display device which is coupled, with respect to signals, with the image determination unit and which is designed for receiving a signalization signal determined by the image determination unit and for signalizing.

12. The display system according to claim 11, wherein the optical display device is coupled with respect to signals with the image determination unit by way of a specified multimedia interface.
