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.

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.
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.
