- a vehicle display system is proposed with a position-variable reflection means (adjustable element), for example a mirror, by means of which the projection surface is adjustable in space, and a correction means by which on the projection surface perceptible aberrations are compensated (such as by predistortion in the image or via an optical element located in the beam path), wherein the effect of the correction means can be changed and parameters influencing the action of the correction means are determined by a measuring method.
- measurements are carried out for a plurality of layers (or positions) of the reflection means and thus of several locations of the projection surface, and the determined correction parameters are stored in a memory associated with the display device.
- the measurements may be performed using a height-adjustable camera that represents various head positions of motor vehicle operators due to body size or seat adjustment.
- an individually adjustable projection vehicle display system is shown with adjustment-dependent variable compensation of image errors, as they occur for example by manufacturing scattered vehicle individually, the determination and deposit of the correction parameters with advantage already during vehicle production takes place.
- the change in position of the virtual image is a change of the virtual image along a vertical axis. In this way, a height adaptation of the virtual image for adaptation to different positions of the eyes of the driver or user of the vehicle display system (due to different body size and / or posture) can be achieved in a simple manner.
- the change in position of the virtual image is a change of the virtual image along a vertical and a horizontal axis.
- a sensor means is provided for detecting the viewing position of the user.
- a sensor means for detecting the viewing position of the user.
- due to the distortion characteristic of the optical system occurring display errors that depend on the head position, ie in particular depend on the viewing angle, particularly effectively by means of the preset (and depending on the height adjustment of the vehicle display system or in dependence of the height and lateral adjustment the vehicle display system) correction data can be compensated.
- the determination of the head position or eye position of the user according to the invention can be done either passive or active.
- a passive determination of the head position is for example possible by the image supplied by the detection device or the camera image is searched for the relative position or position of a pattern, the geometry and contrast as a part of the user's face, in particular as an eye , is identified.
- the head position it is also possible according to the invention for the head position to be determined actively, for example by illuminating the viewer or the driver by an IR light source, which is easily detectable on the image recorded by the camera , from the eye caused light reflexes causes.
- an additional advantage of such a sensor means may also be provided as a means of observation of the driver, an alternative use of the camera.
- the occurrence of signs of fatigue for example slowed eye blink or characteristic eye movements
- visual warnings can then be generated by the imaging element and thus given to the driver for information.
- the risk to the user can be reduced by falling asleep, for example by optimally adjusting an existing headrest.
- the adjustment of the height adaptation functionality of the vehicle display system is performed manually by the user.
- the adjustable element is a movable mirror element, in particular a rotatable mirror element and / or a translatable mirror element is.
- a projection of image information from the display device onto the windshield is provided for generating the virtual image, wherein the distortion of the virtual image due to a reflection on the windshield and the distortion by the correction means mutually in Essentially cancel.
- a change in the display of the display device is provided to bring about the distortion of the correction means and / or that for causing the distortion of the correction means, a change in the distortion characteristic of the optical system, in particular a contour change of an optical element and / or a mirror and / or a lens is provided.
- the distortion correction can take place in a particularly simple manner.
- Another object of the present invention relates to a method for calibrating a vehicle display system according to the invention, wherein for different positions of the virtual image by means of a detection device, the distortion of the virtual image is measured and derived derived position-dependent correction data for setting correction means and stored in the memory device of the vehicle display system.

- the light source 20 may either be part of the vehicle display system 10 or may be separate therefrom.
- the light emitted according to the first direction 41 or propagating in the first direction 41 is transmitted through the optical system 40 inventively deflected in particular several times.
- a first deflecting mirror 45 is provided, which deflects the light arriving in the first direction 41 in a second direction 42.
- the light propagating in the second direction 42 is in turn reflected by a second deflecting mirror 47 and deflected in a third direction 43.
- the light propagating in the third direction 43 is again reflected by a windshield 48 and deflected in a fourth direction 44.
- the fourth direction 44 is directed toward the eye of the observer 60.
- the second deflecting mirror 47 is formed as a so-called adjustable element 47 in the context of the embodiment shown in the figure 1. This means that a movement of the adjustable element 47, a change in the height adjustment of the virtual image can be made.
- the first mirror or the first deflection mirror 45 is designed as an adjustable element 47. In the following, however, the adjustable element 47 is always designated by the reference numeral 47.
- the adjustable element 47 is any element of the optical system 40 or of the display device 30 which has height adaptation (or height and side adaptation) of the virtual image by either different (ie approximately at different angles) projection onto the virtual image Windscreen and / or ("equal", ie at the same angle) projection on different areas of the windshield for projection of the virtual image allowed.
- the adjustable element 47 For different settings of the adjustable element 47 are usually make different corrections to the projected image, which by a correction means are generated as part of the optical system 40.
- the different adjustments or corrections to be made for different settings of the adjustable element 47 are stored as correction data in a memory device of the vehicle display system. For example, multiple sets of correction data may be stored for different discrete adjustment positions. Depending on which of the discrete adjustment positions of the adjustable element 47 (and thus which of the accessible or adjustable height positions (or height and side positions) of the virtual image) has been selected, then a different set of correction data is used for the image correction.
- the correction means changes the representation of the virtual image. This can be done, for example, by influencing the image-forming element 30 or the display device 30.
- the correction means is either part of the display device 30 or the correction means affects at least the display device 30.
