Method for Representing Items of Information in a Means of Transportation, and Instrument Cluster for a Motor Vehicle

Abstract

In a method for displaying items of information in a transportation device, the items of information are displayed in the form of hierarchical menu structures. A device for displaying items of information includes a control unit and a display unit for the stereoscopic and/or autostereoscopic display of items of information. In the method, the display is implemented stereoscopically, at least two different menus or menu items being displayed to the viewer at different distances. The instrument cluster includes the placement of a mask in front of the display of a display unit, the mask modifying the light emission of the light emitted by the display so as to result in a display of autostereoscopic images.

What is claimed is: 
     
         1 . An instrument cluster for a motor vehicle for displaying items of information in close proximity to a primary visual field of a driver, comprising:
 a display unit having a display;   a control unit configured to control the display; and   a mask arranged in front of the display and configured to modify light emission of light emitted by the display such that autostereoscopic images are displayed on the display unit.   
     
     
         2 . The instrument cluster according to  claim 1 , wherein the mask includes a wavelength-selective filter mask. 
     
     
         3 . The instrument cluster according to  claim 1 , wherein the display unit includes a flat screen on which an optical structure mask is affixed and is configured to allows separation of partial images for an autostereoscopic display. 
     
     
         4 . The instrument cluster according to  claim 1 , wherein a resolution of the display unit in a horizontal direction is greater than  150  dpi. 
     
     
         5 . The instrument cluster according to  claim 1 , wherein the control unit is configured to control the display unit to represent a display image such that at least eight autostereoscopic images are displayable simultaneously, the images emittable in a horizontal visual fan. 
     
     
         6 . The instrument cluster according to  claim 5 , wherein a plurality of stereoscopic visual fans is generatable next to each other and form a visual zone. 
     
     
         7 . The instrument cluster according to  claim 5 , wherein a horizontal cone angle of the visual fan is greater than 15°. 
     
     
         8 . The instrument cluster according to  claim 7 , wherein the horizontal cone angle is between 25° and 30°. 
     
     
         9 . The instrument cluster according to  claim 1 , further comprising a device configured to track eye position connected to the control unit; the mask displaceable in a plane parallel to the display device; displacement of the mask implementable as a function of a signal of the device configured to track the eye position. 
     
     
         10 . The instrument cluster according to  claim 1 , wherein the display includes an area for displaying at least one of (a) a speed and (b) an engine speed in the form of a dial-type gauge. 
     
     
         11 . The instrument cluster according to  claim 1 , wherein the display includes an area for displaying at least one of (a) a radiator temperature and (b) a fuel level of a tank. 
     
     
         12 . The instrument cluster according to  claim 1 , wherein the display includes an area for stereoscopically displaying a compass, in which a compass dial is viewable obliquely from above. 
     
     
         13 . A motor vehicle, comprising:
 an instrument cluster configured to display items of information in close proximity to a primary visual field of a driver, the instrument cluster including:   a display unit having a display;   a control unit configured to control the display; and   a mask arranged in front of the display and configured to modify light emission of light emitted by the display such that autostereoscopic images are displayed on the display unit   
     
     
         14 . The motor vehicle according to  claim 13 , wherein the instrument cluster is arranged underneath a windshield. 
     
     
         15 . The motor vehicle according to  claim 14 , wherein the instrument cluster is arranged behind a steering wheel. 
     
     
         16 . The motor vehicle according to  claim 13 , further comprising an operating device connected to the control unit and actuable in a three-dimensional manner, the control unit configured to control the display unit such that three-dimensional actuation of the operating device is reproduceable autostereoscopically.
