Turn by turn graphical navigation on full windshield head-up display

摘要

A system to display graphical images upon a windscreen of a vehicle including navigational aids includes the windscreen having a transparent windscreen head up display, an enhanced vision system manager monitoring a planned travel route, and generating display requirements based upon the planned travel route. The system further includes a graphics system generating the graphical images to be displayed based upon the display requirements, and a graphics projection system communicating with the graphics system and displaying the graphical images.

1. System to display graphical images upon a windscreen of a vehicle including navigational aids, the system comprising:
the windscreen comprising a transparent windscreen head up display; an information system comprising:
a global positioning device, anda map database; a navigation system configured to determine a position of the vehicle within a lane currently being traveled by the vehicle based upon data from the information system; a device monitoring informational inputs representing an operational environment for the vehicle comprising one of road geometry in front of the vehicle and objects proximate to the vehicle, the device comprising one of a camera device and a radar device; an enhanced vision system system manager
monitoring a planned travel route and the informational inputs, andgenerating display requirements based upon the planned travel route and the informational inputs, said display requirements including navigational graphics providing turn by turn navigational instructions based upon GPS data improved by the informational inputs, wherein each navigational graphic is registered to overlay a portion of a road surface visible through the windscreen whereat a corresponding maneuver is required to follow the planned route, and wherein a size of each registered navigational graphic is cyclically increased as a distance between the vehicle and a location whereat the corresponding maneuver is required decreases based upon the position of the vehicle determined by the navigational system; a graphics system generating the graphical images to be displayed based upon the display requirements; and a graphics projection system communicating with the graphics system and displaying the graphical images; wherein the display comprises one of a plurality of light emitting particles, with each light emitting particle having a diameter less than 500 nanometers, and a plurality of micro-structures configured to scatter light from the display; wherein generating display requirements based upon the informational inputs further comprises including within the display requirements one of lane change instructions based upon the informational inputs and a navigational graphic based upon avoiding the objects proximate to the vehicle.
