Abstract

A method to display a registered driving path image upon a transparent windscreen head-up display in a source vehicle includes monitoring an operating environment of the source vehicle, monitoring a driver registration input, determining a registered driving path image based upon the operating environment of the source vehicle and the driver registration input, and displaying the registered driving path image upon the head-up display.

Claims (46)

1. Method to display a registered driving path image upon a transparent windscreen head-up display in a source vehicle, the method comprising:

monitoring an operating environment of the source vehicle travelling upon a road surface, comprising:

monitoring a location of the source vehicle through a global positioning device, and

determining a geometry of the road surface proximate to the source vehicle based upon the location of the source vehicle and a three dimensional map database;

monitoring a driver registration input;

determining a registered driving path image defining a recommended plot for the source vehicle to use for travel upon a given section of the road surface based upon the operating environment of the source vehicle and the driver registration input, comprising:

when the given section of the road surface comprises a curved section, the registered driving path image including a closest point to an inside edge of the curved section that the source vehicle should reach during a turning maneuver through the curved section to enable a maximum desired vehicle speed at an exit of the curved section;

when the source vehicle operates upon public roads:

monitoring a driving priority;

monitoring historical driving paths cross-referenced with the driving priority, wherein the registered driving path image is based upon the historical driving paths; and

displaying the registered driving path image upon the head-up display.

2. The method of claim 1 , wherein monitoring the operating environment of the source vehicle further comprises:

monitoring a vehicle sensor device; and

wherein determining the road geometry proximate to the source vehicle is further based upon the monitored vehicle sensor device.

3. The method of claim 1 , wherein determining the registered driving path image comprises determining an ideal driving path illustrating a recommended path for the source vehicle irrespective of a current position of the source vehicle with respect to the road surface.

4. The method of claim 1 :

wherein the operating environment of the source vehicle comprises a current position of the source vehicle with respect to the road surface; and

wherein the registered driving path image comprises a tactical driving path image illustrating a recommended path for the source vehicle.

5. The method of claim 4 , further comprising:

determining an ideal driving path image illustrating a recommended path for the source vehicle irrespective of the current position of the source vehicle with respect to the road surface; and

displaying the ideal driving path image upon the head-up display.

6. The method of claim 1 wherein the operating environment of the source vehicle further-comprises monitoring a location of traffic proximate the source vehicle.

7. The method of claim 1 , wherein the source vehicle comprises a racing source vehicle operating upon a closed course.

8. The method of claim 1 , wherein the driving priority comprises fuel economy.

9. The method of claim 1 , wherein monitoring the operating environment of the source vehicle further comprises monitoring a planned route of travel when the source vehicle operates upon public roads.

10. The method of claim 1 , wherein monitoring the operating environment of the source vehicle further comprises monitoring an obstacle in a roadway.

11. The method of claim 10 , wherein monitoring the obstacle in the roadway comprises monitoring historical data stored in a database.

12. The method of claim 10 , wherein monitoring the obstacle in the roadway comprises monitoring vehicle-to-vehicle communications from another vehicle located in front of the source vehicle.

13. The method of claim 1 , further comprising:

monitoring a current location and orientation of the source vehicle; and

comparing the current location and orientation of the source vehicle to an ideal driving path to determine a driving path variance; and

wherein determining the registered driving path image is further based upon the driving path variance.

14. The method of claim 1 , wherein the operating environment of the source vehicle comprises a proximity to an emergency vehicle.

15. System to display a registered driving path image upon a transparent windscreen head-up display in a source vehicle, comprising:

a transparent windscreen head-up display;

an enhanced vision system

monitoring an operating environment of the source vehicle travelling upon a road surface, comprising:

monitoring a location of the source vehicle through a global positioning device, and

determining a geometry of the road surface proximate to the source vehicle based upon the location of the source vehicle and a three dimensional map database,

monitoring a driver registration input, and

determining a registered driving path image for a given section of the road surface based upon the operating environment of the source vehicle and the driver registration input, comprising

when the given section of the road surface comprises a curved section, the registered driving path image including a closest point to an inside edge of the curved section that the source vehicle should reach during a turning maneuver through the curved section to enable a maximum desired vehicle speed at an exit of the curved section;

when the source vehicle operates upon public roads:

monitoring a driving priority;

monitoring historical driving paths cross-referenced with the driving priority, wherein the registered driving path image is based upon the historical driving paths; and

a graphic projection system displaying the registered driving path image upon the head-up display.
