Abstract: An operating method for a vehicle head-up display device has an imaging unit, which is designed to generate a light beam with display content, and a partially transparent reflecting plate which is disposed in a user's field of view, reflects the light beam to their eye box and thereby presents the display content to them in a virtual image plane behind the reflecting plate. The particular display content is divided into a plurality of presentation sub-areas, each of which is pre-distorted, as it is generated in the imaging unit, using an associated individual digital warping matrix which is predetermined or dynamically determined independently of the other presentation sub-areas, so that the individual sub-areas can be presented in the virtual image plane with different perspective characteristics.

Abstract: An LCD display unit for a reflection display system in a motor vehicle includes an LCD pixel matrix for selectively controlling picture elements for presenting a display image on a display area; a backlight arrangement, which is divided into selectively controllable dimming zones in order to illuminate regions containing multiple picture elements with background light; and a control unit, which is configured to control the LCD pixel matrix so that the display image is output, the display image being distorted using a warping function in order to compensate for a distortion of the display image as a result of reflection from a reflection region. The dimming zones have a shape and a size determined by the warping function.

The system includes a display unit which is designed to display the display image on a display surface, a detection sensor system for detecting the displayed display image on the display surface, and a control unit which is designed to actuate the display unit for displaying purposes, ascertain detection information on the basis of the detected displayed display image, ascertain the presence of a foreign object on the display surface of the display unit on the basis of the displayed display image and on the basis of the detection information, and signal a disruption of the display if the presence of a foreign object on the display surface of the display unit has been ascertained.

Abstract: A method, apparatus and computer software for fault management for a vehicle having at least one camera unit configured to provide image data includes a step of, responsive to detection of a respective fault condition in relation to the vehicle, creating a respective fault entry which is representative of information relating to the respective detected fault condition. Respective image data of the at least one camera unit is requested depending on the respective detected fault condition in such a way that the respective image data has a temporal reference to the respective detected fault condition. The respective requested image data is assigned to the respective fault entry.

Abstract: A method for operating a reflection display system for displaying a display image for a vehicle occupant of a motor vehicle by reflection of the display image on a reflection surface, in particular on a front windscreen, includes outputting a sequence of measurement display images with different patterns with different lighting intensities in some regions; detecting a brightness signal by an ambient brightness sensor while each measurement display image of the sequence is being displayed in order to obtain a brightness profile of the brightness signals; evaluating the profile of the brightness signals with respect to a predefined reference brightness profile which specifies brightness signals when the display surface is uncovered, for the sequence of measurement display images with constant ambient brightness; and signaling the presence of a foreign object on the display surface depending on the result of the evaluation.

Abstract: A display screen for a reflection display system in a motor vehicle has, for arrangement in front of or on a lower region of the windshield, a reflection layer, in order to reflect a display image in a display region without a double image.
