Method of using GPS map information to highlight road markings on a head up display that otherwise may be non-visible due to inclement weather

1. A head up display arrangement for a motor vehicle, the arrangement comprising:

a global positioning system module configured to emit geographic location coordinates associated with the motor vehicle;

an electronic processing device communicatively coupled to the global positioning system module, the electronic processing device being configured to:

receive the geographic location coordinates;

retrieve from a database lane marking location data stored in association with the received geographic location coordinates; and

transmit the retrieved lane marking location data; and

a head up display communicatively coupled to the electronic processing device and configured to:

receive the transmitted lane marking location data; and

display virtual lane markings dependent upon the received lane marking location data, wherein the virtual lane markings comprise transparent colored highlighting.

2. The head up display arrangement of claim 1 wherein the electronic processing device is configured to determine a direction of travel of the motor vehicle, the lane marking location data being stored in the database in association with corresponding said directions of travel.

3. The head up display arrangement of claim 1 wherein the lane marking location data comprise positions of the lane markers in the driver's field of view.

4. The head up display arrangement of claim 1 wherein the global positioning system module, the database, the electronic processor, and the head up display are each disposed within the motor vehicle.

5. The head up display arrangement of claim 1 wherein the database is disposed remotely from the vehicle, and the electronic processing device is configured to wirelessly retrieve from the database the lane marking location data.

6. The head up display arrangement of claim 1 wherein the virtual lane markings are displayed such that the virtual lane markings are superimposed over locations of actual lane markings.

7. A method of providing a head up display in a motor vehicle, the method comprising:

receiving a set of said geographic location coordinates, the set of geographic location coordinates being associated with a position of the motor vehicle at a particular point in time;

retrieving from storage a set of said lane marking location data, the set of lane marking location data being stored in association with the received set of geographic location coordinates; and

displaying virtual lane markings on a head up display within the motor vehicle, the displaying being dependent upon the retrieved set of lane marking location data, wherein the virtual lane markings comprise transparent colored highlighting.

8. The method of claim 7 further comprising determining a direction of travel of the motor vehicle, the lane marking location data being stored in association with corresponding said directions of travel.

9. The method of claim 7 wherein the lane marking location data comprise positions of the lane markers in the driver's field of view.

10. The method of claim 7 wherein each of the steps occurs entirely within the motor vehicle.

11. The method of claim 7 wherein the lane marking location data is stored remotely from the motor vehicle, and the set of said lane marking location data is wirelessly retrieved from storage.

12. The method of claim 7 wherein the virtual lane markings are displayed such that the virtual lane markings are superimposed over locations of actual lane markings.

13. A head up display arrangement for a motor vehicle, the arrangement comprising:

a global positioning system module configured to emit current geographic location coordinates associated with the motor vehicle;

an electronic processing device communicatively coupled to the global positioning system module and to the database, the electronic processing device being configured to:

receive the current geographic location coordinates;

forecast, based on the received current geographic location coordinates, future geographic location coordinates associated with the motor vehicle at a future time;

retrieve from a database lane marking location data stored in association with the forecasted future geographic location coordinates; and

transmit the retrieved lane marking location data; and

a head up display communicatively coupled to the electronic processing device and configured to:

receive the transmitted lane marking location data; and

display, at the future time, virtual lane markings dependent upon the received lane marking location data, wherein the virtual lane markings comprise transparent colored highlighting.

14. The head up display arrangement of claim 13 wherein the electronic processing device is configured to determine a direction of travel of the motor vehicle, the lane marking location data being stored in the database in association with corresponding said directions of travel.

15. The head up display arrangement of claim 13 wherein the lane marking location data comprise positions of the lane markers in the driver's field of view.

16. The head up display arrangement of claim 13 wherein the global positioning system module, the database, the electronic processor, and the head up display are each disposed within the motor vehicle.

17. The head up display arrangement of claim 13 wherein the database is disposed remotely from the vehicle, and the electronic processing device is configured to wirelessly retrieve from the database the lane marking location data.

18. The head up display arrangement of claim 13 wherein the virtual lane markings are displayed such that the virtual lane markings are superimposed over locations of actual lane markings.

19. The head up display arrangement of claim 18 wherein the virtual lane markings are displayed such that the actual lane markings are not visible.

20. The head up display arrangement of claim 18 wherein the virtual lane markings are displayed such that the actual lane markings are visible.
