Vehicle simulator having head-up display
First Claim
1. A vehicle simulator for a human user for simulating a real vehicle having an actual head-up display that displays a real head up display image and has optical characteristics that limit viewing of the real head up display image from some points of view within the real vehicle, said simulator comprising:
- a tracking apparatus providing a time-dependent signal relatable to or representative of a position of an eye of the user;
an image system forming a visual image viewable by the user, said image including a scene representing a simulated out-the-window view outside the vehicle and a simulated head-up display image simulating the real head up display image and superposed on said scene;
said image system generating said simulated head-up display image using the signal provided by the tracking apparatus so that the simulated head-up display image displayed to the user is limited when the tracking apparatus signal indicates that the user is viewing the simulated head-up display from a point of view wherein the optical characteristics of the actual head-up display in the real vehicle limit viewing of the real head up display image thereof.

Abstract
A vehicle simulator having a projection system for projecting a generated scene and symbology onto a common viewing screen. Tracking apparatus is provided for providing position and/or angular orientation signals representative of the eye of a person viewing the projected scene and symbology. An image generation system is included for generating the scene and symbology for the projection system, such scene and symbology being generated as a function of the position and/or angular orientation signals provided by the tracking apparatus. Such symbology is representative of symbology produced by a head-up display. The image generation system generates the scene and symbology with characteristics which simulate vignetting and/or occulting effect characteristics of the head-up display. The OTW scene and symbology are projected onto a screen and are co-located while the image generator, base or data of the eye position of the user, produces the symbology to simulate the collimation, vignetting and occulting effects of the HUD optical type used in the vehicle that is simulated.

27. A method of simulating a vehicle for a user, said method comprising:
-
determining a position of an eye of the user; projecting on a simulator screen an out-the-window scene corresponding to a simulated situational environment of the vehicle; deriving a simulated head-up display image from the determination of the position of the eye of the user using a model of occulting or vignetting of an optical system of a HUD display for the vehicle so that a portion of said simulated head-up display image is occulted when the determined position of the eye of the user is one in which said portion of the simulated head-up display image would be occulted in a HUD display in the vehicle being simulated; and projecting said simulated head-up display image on said screen. - View Dependent Claims (28, 29, 30)
