Definitions
- the invention relates to display systems for motor vehicles for the visual representation of driving and vehicle-relevant information, navigation, communication and/or media information.
- the invention further relates to measures for suppressing glare caused by reflected ambient light incident on the display surface of a display device.
- a large number of display devices are installed in motor vehicles, which can be designed as simple illuminated symbols, pointer instruments or screen displays.
- the display devices are arranged in such a way that the driver can grasp the information to be transmitted as quickly as possible.
- projection displays such as head-up displays
- a combiner surface in particular in the form of a reflection surface on the windshield, is used to reflect a light beam projected by the projection device, so that the image to be displayed can be perceived by the driver without changing the direction of view.
- projection devices for head-up displays require a considerable amount of installation space, and in smaller motor vehicles in particular it is difficult to implement a large-area display in the form of a head-up display, since the installation space required for this is not available within the instrument panel, i.e. under the top of the instrument panel.
- panoramic HUD displays are known, which are formed by arranging display devices on the upper side of an instrument panel. These produce a bright display image on their display surface, which is reflected via a lower area of the windshield into the eye area of a vehicle occupant. Such a panoramic HUD display therefore does not require a complex optical system, and the display image reflected there can be seen by all vehicle occupants via the windshield. There is no option with such display devices to show certain image content only to one or some of the vehicle occupants.
- Such conventional panoramic head-up display systems which reflect a display image via the transparent area of the windscreen, lack the necessary contrast of image perception, so that such a display device cannot be approved as the sole display for legally required displays in motor vehicles.
- a reflection can be made via an opaque lower area of the windscreen, also known as the black print area or pane root area. Since the upper edge of this black print area must not restrict the line of sight vertically downwards by less than 4° compared to the horizontal due to legal requirements, the height of the black print area is limited.
- a reflection display system in a vehicle comprising:
- the display surface is inclined rearward relative to the horizontal with respect to the longitudinal direction of the vehicle.
- a windscreen can extend rearward at an angle of between 45 and 65° relative to a perpendicular to the vehicle longitudinal direction, wherein a lower portion of the windscreen is designed as an opaque reflection surface, wherein a front wall of the recess directly adjoins a lower edge of the windscreen or is offset rearward at a distance of not more than 5 cm from the lower edge of the windscreen relative to a vehicle longitudinal direction.
- one problem is to design it in such a way that an optical display of information with sufficient contrast is possible in all possible eye positions within an eye area (eye box). Furthermore, the arrangement of the display system should avoid direct or indirect glare of vehicle occupants as far as possible.
- the eye area indicates possible positions of pairs of eyes of vehicle occupants sitting on regular vehicle seats.
- the eye area is defined around an eye pair point according to 77/649/EEC as position V2 of the eye pair in the vehicle interior.
- the eye area can be based on this and span an area around the eye pair point V2, which is defined, for example, in the vehicle's longitudinal direction V2 - 200mm to V2 +2000mm, in the transverse direction V2 - 100mm to V2+100mm and in the vertical direction V2 to V2+150mm.
- the above display system can provide for arranging a display device on a bottom surface of a recess in the instrument panel, the front wall of which (with respect to a vehicle longitudinal direction) is immediately adjacent to the lower edge of the windscreen or is offset to the rear at a small distance of no more than 5 cm from the lower edge of the windscreen with respect to a vehicle longitudinal direction. Arranging the recess close to the lower edge of the windscreen enables the best possible use of the entire height of a black print area of the windscreen for reflecting the display image.
- the arrangement of the display device in the recess prevents a vehicle occupant from directly viewing the display surface of the display device.
- the display surface of the display device is arranged at the bottom of the recess in such a way that a rear edge of the recess with the top of the instrument panel does not allow a direct view of the display surface from the eye area of the vehicle occupants. Conversely, this means that the recess has a corresponding depth.
- the black print area represents a blackened area, i.e. non-transparent area, in a lower part of the windscreen and serves to reflect the display image of the display device so that a vehicle occupant (with a pair of eyes in the eye area) can perceive a display image in the black print area with high contrast without interference from external light.
- the reflection surface has an upper edge that limits the viewing angle of the vehicle's surroundings to no less than 4° downwards from the horizontal for all eye positions within the defined eye area (eye box). (4° only applies to drivers)
- the distance between the rear edge of the display surface (with respect to a vehicle longitudinal direction) and the upper edge of the black print area (in the direction perpendicular to the transverse direction of the vehicle) may form a shielding angle to the perpendicular or vertical to the rear between 0 and 20°. This means that ambient light falling on the display surface does not reach the angle range from -90° (from the front) to the shielding angle.
- the arrangement and design of the black print area, the dimensions of the recess and the display surface of the display device are also coordinated in such a way that incident ambient light from the angle range between the shielding angle and the angle of inclination of the windscreen to the perpendicular or vertical to the rear (from the rear in relation to the vehicle's longitudinal direction) does not lead to a direct reflection into the eye of a vehicle occupant.
- the upper edge of the reflection region can be arranged such that a first angle a to the surface normal of the display surface in the longitudinal direction towards the rear satisfies the following relationship: where the first angle ⁇ corresponds to an angle between the surface normal of the inclined display surface and the distance between the rear edge of the display surface and the upper edge of the reflection region in the vertical direction, the second angle ⁇ corresponds to the angle of incidence of the visual ray from the eye pair point onto the front pane with respect to the surface normal of the front pane and d corresponds to the smallest distance of the front edge of the display surface to the front pane.
- angles 17° ⁇ a ⁇ 53°, 60° ⁇ ß ⁇ 80°, and 5mm ⁇ d ⁇ 25mm can be selected If ambient light or direct sunlight falls through the windscreen directly onto the display surface of the display device, the inclination of the display surface causes the ambient light to be reflected onto the black print area and from there onto the absorption surface or directs the reflection safely in a direction outside the eye area. In this way, vehicle occupants are prevented from being dazzled by reflected ambient light even if ambient light falls on the display surface at an angle.
- a rear wall (with respect to a vehicle longitudinal direction) can be provided with a recess with an optically weakly reflective or light-absorbing absorption surface onto which ambient light incident from outside can be reflected.
- the absorption surface thus serves as a mirror bank to eliminate ambient light from the display system so that it does not reach the eye area.
- the edge that the recess forms with the top of the instrument panel thus serves on the one hand to prevent a vehicle occupant from directly viewing the display surface of the display device and on the other hand as the upper edge for the absorption surface.
- such a display system can be designed over the entire width of the windscreen. To do this, it is sufficient to arrange several display devices, in particular at a distance along the windscreen in a corresponding recess. The display devices are arranged at an angle to one another according to the curvature of the windscreen, so that an essentially horizontal image is perceived in the reflection area of the windscreen.
- the display surfaces can be arranged at an obtuse angle to each other in the horizontal plane, depending on the curvature of the front panel.
- the The corners of each of the display surfaces facing the windscreen are the same distance from the windscreen.
- the display surfaces can be inclined inwards to the vertical, i.e. around a vehicle longitudinal axis (x-direction), so that in the case of several display devices, an interior of the display surfaces is arranged parallel to the horizontal and the display surfaces offset from the centre in the y-direction (transverse direction) are each inclined with their outer edge upwards or downwards, so that a substantially horizontal image is perceived via the curved reflection surface of the windscreen.
- curvatures of the windshield can be compensated by pre-distortion (warping) of the display contents, so that a floating, seemingly continuous display image is created for the vehicle occupants.
- the display surfaces can be arranged according to the curvature of the front pane with an obtuse angle to each other with respect to a rotation about the z-direction, so that the average distance from a lower edge of the front pane is the same or as constant as possible.
- the angle of rotation around the z-direction can be between 0 and 25°.
- the display surfaces can be inclined inwards around a vehicle's longitudinal axis in accordance with the curvature of the windscreen to the vertical, so that in the case of several display devices, a middle display surface is arranged parallel to the horizontal and the display surfaces offset from the center in the transverse direction (y-direction) are each inclined with their outer edge upwards or downwards, so that an essentially horizontal image is perceived on the reflective surface of the windscreen.
- the corresponding angle of inclination can be between -22° (downwards) and +22° (upwards).

- Figure 6 is a schematic representation of the dimensions and angle designations of the display device.
- Figures 7a and 7b show a plan view of a motor vehicle and a schematic interior view illustrating the arrangement of several display devices distributed across the width of the vehicle.
- Figures 1 a and 1 b show a schematic longitudinal sectional view through a motor vehicle with a reflection display system 1 and a view from the perspective of the driver of the motor vehicle.
- the reflection display system 1 has a display device 2 which is mounted on a substantially horizontal extending upper side of an instrument panel 4.
- the instrument panel 4 has a substantially horizontal upper surface 41 which extends substantially over the entire width (perpendicular to the direction of representation) of the motor vehicle 1.
- the display device 2 comprises an upwardly directed display surface 3 for displaying a display image.
- the display device 2 is arranged on the upper side of the instrument panel 4 and in a conventional manner below a section of a windshield 5 which serves as a reflection surface 8.
- the windshield 5 is inclined rearward in a manner known per se with an angle of inclination between 40 and 60° to the vertical with respect to the longitudinal direction of the vehicle.
- the instrument panel 4 has a substantially horizontal upper surface 41 which extends substantially over the entire width (perpendicular to the direction of view) of the motor vehicle 1.
- the reflection surface 8 can extend over a large part of the width of the front pane 5 directly at a lower region of the front pane 5.
- the reflection surface 8 represents a pane root region, which can be designed as a black print region, i.e. non-transparent, wherein the inside of the front pane 5 can be designed to be reflective in the region of the black print region.
- An upper edge 81 of the black print region, at which the front pane 5 becomes transparent, generally has a height of between 8 and 25 cm from the lower edge of the front pane 5, particularly depending on the inclination of the front pane 5.
- the upper edge 81 of the reflection surface 8 forms a line of sight with a lowest eye position in the eye region B, which is not less than 4° downwards from the horizontal.
- the display device 2 is controlled by a control unit 9 in order to output a desired display image as a display image, which is to be perceived by the vehicle occupant after reflection via the reflection surface 8.
- the display device 2 is preferably designed as a light-emitting display device, in particular as an LCD display unit with a high-brightness backlight or as a micro-LED display unit in order to provide a bright display image.
- the display device 2 adjoins the lower edge 51 of the windscreen 5 or is only a short distance away from it, e.g. up to 5 cm, so that the display device 2 extends rearward into the interior 4 of the motor vehicle 1.
- the display device 2 can be mounted in the recess 6 on the upper side 41 of the instrument panel 4 such that the vehicle occupant cannot have a direct view (visual ray S dashed) of the display surface 3 of the display device 2 and the vehicle occupants are prevented from being dazzled by direct display light from the display surface 3 into the eye area B.
- the recess 6 forms an edge K with the upper side of the instrument panel 4, which has a height with respect to the display surface of the display device 2 arranged in the recess 6, so that no direct view of the display surface 3 of the display device 2 is possible from any possible position of the pair of eyes within the eye area B.
- the eye area can extend around a position V2 in accordance with standard 77/649/EEC.
- the eye area can be defined starting from the eye pair point of position V2, which can extend in the vehicle longitudinal direction V2 - 200mm to V2 +2000mm, in the transverse direction V2 - 100mm to V2+100mm and in the vertical direction V2 to V2+150mm.
- the display surface 3 of the display device 2 is arranged such that a display image to be output is reflected on the reflection surface 8 and can be viewed by a vehicle occupant for each Eye position in the eye area B can be perceived.
- the position of the eye area B, the angle of the front screen 5 and its distance from the eye area B and the distance of the display surface 3 from the lower edge of the reflection surface 8 are coordinated with one another, so that an output display image can be perceived completely via the reflection surface 8 by both a lowest and an uppermost position of a pair of eyes in the intended predetermined eye area B.
- the recess has a front wall 61 and a rear wall 62, whereby the rear wall 62 can be designed as an absorption surface, i.e. as a weakly reflective surface.
- the wall 62 is preferably aligned such that it cannot be seen from the eye area B, either directly or via the reflection in the front window 5 or reflection surface 8.
- the upper edge 81 of the reflection surface 8 can be arranged to extend directly above a rear edge of the display surface 3 with respect to a vertical or can be arranged further rearward so that first ambient light U1 from a first angle range W1 between -90° (frontward) to the vertical and a shielding angle does not fall directly on the display surface 3.
- the upper edge of the black print area can be offset further rearward so that a shielding angle between 0° and 40° is formed between the rear edge of the display surface 3 and the upper edge 81 of the reflection surface 8 to the vertical.
- directly incident second ambient light U2 can be totally reflected on the inside of the front pane 5 in a second angular range W2 between 40° and 90°.
- the edge K can additionally prevent ambient light from the angular range between the angular ranges W2 and W3 from falling on the display surface, thus protecting the display surface from overheating and from harmful light emissions.
- Incident third ambient light U3 from directions within a third angular range W3 between the shielding angle and the lower angle of the second angular range W2 can reach the display surface 3.
- the display surface 3 can be tilted backwards with respect to the horizontal in order to reflect the third ambient light U3, which is not totally reflected, is shielded by the reflection surface 8 or is shielded by the edge K of the recess, onto a lower region of the reflection surface 8, from where it is directed onto the absorption surface of the rear wall 62 of the recess 6.
- the third ambient light U3, which is reflected twice in this way, is absorbed on the absorption surface and thus cannot lead to glare for a vehicle occupant.
- Figure 6 shows the angle designations of the reflection angle ß at the reflection surface 8, the angle a of the distance between the rear edge G of the display surface 3 and the upper edge 81 of the reflection surface and the distance of the front edge D of the display surface 3 from the front pane 5.
- the upper edge 81 of the reflection region 8 can be arranged such that a first angle a to the surface normal of the display surface 3 in the longitudinal direction towards the rear satisfies the following relationship: where the first angle a corresponds to an angle between the surface normal of the inclined display surface 3 and the distance between the rear edge G of the display surface 3 and the upper edge 81 of the reflection region 8 in the vertical direction, the second angle ß corresponds to the angle of incidence of the visual ray from the eye pair point onto the front pane 5 with respect to the surface normal of the front pane 5 and d corresponds to the smallest distance of the front edge D of the display surface 3 to the front pane 5.
- angles 17° ⁇ a ⁇ 53°, 60° ⁇ ß ⁇ 80° and the distance d with 5mm ⁇ d ⁇ 25mm can be selected
- FIG. 7a As shown in the schematic plan view of the vehicle in Figure 7a and the interior view in Figure 7b, several separate display devices 2 can be arranged in corresponding recesses in the instrument panel 4 distributed over the width W of the vehicle or the width of the windscreen 5.
- the essentially rectangular display devices 2 can follow the curved contour of the lower edge 51 of the windscreen 5.
- the display surfaces 3 can be rotated around the z-direction, i.e., for example, in the case of several display devices 2, a middle one of the display devices 2 can be arranged with its surface parallel to the horizontal and with its longitudinal dimensions parallel to the transverse direction (y-direction).
- the outer display devices 2 (offset from the center in the width direction) can be arranged with respect to their longitudinal directions at an angle of rotation ö in the horizontal so that the arrangement adapts to the curvature of the front screen 5.
- the angle of rotation ö around the z-direction can be between 0° and 25°, with 0° corresponding to the transverse direction.
- the display surfaces 3 can be inclined to the vertical in the longitudinal direction (x-direction), ie, for example, in the case of several display devices 2, a middle one of the display devices 2 can be arranged with its surface parallel to the horizontal and the outer display devices 2 (offset from the center in the width direction) can each be inclined with their outer edge upwards or downwards by an inclination angle £.
- the inclination angle can be between -22° and +22°. This enables curved front screen 5 provides an essentially unadulterated representation of information about the reflection surface 8.
- the display image shown on the display device 2 can be transformed using the control unit 9 in order to present the reflected display image to a vehicle occupant with as little distortion as possible.
