Problems solved by technology
However, known systems that project light directly onto the windshield typically require coatings or materials that greatly reduce the transparency of the windshield
As a result, head-up displays are often restricted to a limited area on the windshield

Embodiment Construction
[0076] Now referring to the accompanying drawings, the accompanying drawings are only for the purpose of illustrating certain exemplary embodiments, and are not used to limit the embodiments. It discloses a vehicle windshield using an enhanced vision system (EVS, enhanced vision system). A method for displaying graphic images on glass, the graphic images describing the operating environment of the vehicle. The graphic images come from sensors and / or data inputs that describe the operating environment, and include processing of these inputs to convey key information to the operator or occupant of the vehicle. The graphic image to be displayed on the windshield is additionally registered to the visible related features observable through the windshield, so that the occupant who wants to see can view the related features and the registered graphics in a separate recognizable input way image.

A method to selectively project graphical images upon a transparent windscreen head up display of a vehicle based upon visual information present in a peripheral zone of vision includes monitoring a location of visual information corresponding to critical information with respect to the windscreen, processing the location of the visual information to generate display requirements describing the visual information as present in the peripheral zone of vision, generating the graphical images to be projected based upon the display requirements, and projecting the graphical images upon the transparent windscreen head up display based upon the estimated operator gaze location.
Description
[0001] Cross references to related applications [0002] This application is a continuation of the U.S. application with application number 12 / 417,077 filed on April 2, 2009, which is incorporated herein by reference. Technical field [0003] The invention relates to image imaging on the windshield of a motor vehicle. Background technique [0004] The content in this section only provides background information related to the present invention and does not constitute prior art. [0005] It is desirable to provide information to the operator of the vehicle in an effective manner and reduce operator fatigue. Display technology is known, in which light is projected onto a screen and the light is transformed into a visible display on the screen. Such displays for transportation purposes are known as head-up displays, in which information is projected onto the sun visor, the screen between the operator and the windshield, or directly onto the windshield. However, known systems that proj...
