Description

The invention relates to a motor vehicle with a display system.

For an occupant of a motor vehicle, in particular a driver of the motor vehicle, it can be of interest to have vehicle-related information displayed while driving the motor vehicle. Based on the vehicle-relevant information displayed, the occupants can, for example, visually use optical signals to establish a connection attempt to communicate with a person outside the motor vehicle, an acceleration process to reach a set target speed, an intended steering process selected by actuating a direction indicator or the charge level of a mobile terminal device coupled to the motor vehicle signals are issued. In this context, the optical signals can be used to generate a real and/or virtual image against a black background, for example in the field of screen printing.

To this end, the DE 10 2009 020 824 A1 a virtual imaging system for multi-layer windshields that reflects an image source off the windshield. For this purpose, the image source can generate light that is reflected on the windshield in such a way that the driver can see a virtual image behind the windshield. The virtual image may be in the form of a laterally arranged plurality of side-by-side displays, each display conveying information to the driver regarding respective selected states of the motor vehicle.

The disadvantage of such a virtual image system is that a large number of display devices have to be provided in order to generate a large-area virtual display.

Alternatively, a laminated glass pane of a conductor foil or printed circuit board arranged between two panes can also be implemented as a display. Such an embodiment is disclosed, for example, by DE 10 2013 003 686 A1 and the DE 10 2015 016 281 A1 .

Furthermore, a display can be provided by means of lighting means, which are arranged between panes of a laminated windshield and can emit light when appropriately stimulated. Such configurations can be found, for example, in WO 2009/122094 A1 , the WO 2017/103426 A1 and the U.S. 2014/355106 A1 .

The disadvantage of such displays integrated into the windshield is that replacing the display and/or the windshield itself involves a great deal of technical effort and high costs.

It is the object of the invention to provide a solution by means of which a virtual image can be provided in a motor vehicle.

The object is solved by the subject matter of the independent claims. Advantageous developments of the invention are described by the dependent claims, the following description and the figures.

The invention is based on the knowledge that a windshield of a motor vehicle itself and components of the motor vehicle arranged on the windshield, such as linings of a dashboard, can be used as a display area of a display system for an occupant of the motor vehicle. For this purpose, at least one image source can emit, that is to say send out, light rays which can be reflected in a reflection area for generating a virtual image. In order to be able to achieve a particularly high contrast in the virtual image, an opaque background, in particular a black background, for example in the area of a so-called black print of the pane, can be used as the reflection area. With such a display, costs for providing and maintaining the display system can be dictated by both the at least one image source and the reflection area. A targeted use of the at least one image source can therefore be sufficient, for example, to selectively display vehicle-related information with sufficient information content, but still allow a driver to look at current traffic events.

The invention provides a motor vehicle with a display system. The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle. Here, the motor vehicle includes a windshield with at least one pane layer. In particular, it is the windshield made of laminated glass, which comprises a plurality of pane layers which are connected to one another by means of a lamination process. The at least one pane layer can be made transparent in a central region, so that when the windshield is installed in the motor vehicle, a passenger can see what is happening on the road. In an edge A screen-printed edge (black print) can be applied in the area of the at least one pane layer, which protects a UV-sensitive adhesive connection from premature aging. Furthermore, the motor vehicle has at least one image source positioned in a dashboard of the motor vehicle, which is set up to emit light beams. For this purpose, the at least one light source can be positioned in the dashboard and emit light rays. The dashboard can be a display or instrument panel with gauges (e.g. for a speedometer and/or a tachometer, indicator lights for a direction indicator) and control levers (e.g. the direction indicator, a high beam) of the motor vehicle. The at least one image source can be in the form of an electric light source, which can be, for example, a semiconductor-based LED light source (light-emitting diode). The emitted light rays are reflected by a reflecting portion to generate a virtual image. This means that the light beams are reflected on a reflecting surface of the reflection area and create the virtual image. The virtual image appears to float in space and is locally decoupled from the reflection area.

The reflection area extends parallel to a side edge of the at least one pane layer, which is arranged on the dashboard when the windshield is installed in the motor vehicle. In other words, the reflection area is arranged in a root area of the windshield, the root area being defined by the respective roots of the respective A pillars of the motor vehicle. In this case, the side edge of the at least one pane layer and a boundary edge of the reflection region, which is arranged opposite the side edge, optionally form two straight lines which lie in one plane and do not intersect one another. According to the invention, the reflection area is arranged along at least one side area of the at least one pane layer on at least one pane surface. In other words, the reflection area is positioned on the side area of the at least one pane layer, so that at least three side edges of the pane layer enclose it, ie delimit the reflection area. This results in the advantage that the reflection area can be provided automatically by means of the built-in windshield. Alternatively or additionally, the reflection area is provided, for example, along at least one component on a windshield frame that is separate from the at least one pane layer. In other words, the at least one separate component includes the reflection area, wherein the at least one component is arranged differently from the windshield and on the windshield frame. For example, it is a cover placed on the dashboard. This results in the advantage that replacing the windshield can be done independently of the display system. Thus, for example, a conventional windshield can be installed that does not have any specific reflection properties.

Furthermore, it can be provided that the at least one image source provides at least one strip display that can be switched exclusively one-dimensionally. In other words, the at least one image source is implemented as the at least one strip display configured to display a visual line. In particular, the at least one strip display can be an LED strip, with surface-mountable light-emitting diodes (SMD-LEDs or surface-mounted device LEDs) being able to be arranged, for example, on a flexible printed circuit board. It is therefore a matter of individual light sources lined up in a chain, which together form the at least one strip display. Since this is a technically simple and extremely robust display that can be implemented over a large length, it can be provided particularly inexpensively and replaced if necessary. A complex display can thus be implemented particularly simply using a small number of image sources, ie the at least one image source, using the at least one strip display. The at least one strip display is positioned parallel to a side edge of the at least one pane layer, which is predetermined by a radius of curvature, and alternatively or additionally to the at least one component. In other words, the side edge of the at least one pane layer and/or the at least one component defines a radius of curvature, with a radius of curvature of the at least one strip display corresponding to this, so that a course of the at least one strip display and a course of the side edge of the at least one pane layer and/or or of the at least one component lie in one plane and do not intersect one another.

In addition, the invention provides that the virtual image is provided by a control device of the motor vehicle. For this purpose, for example, the at least one strip display is selectively controlled by the control device. In this case, a dynamic running light for generating an animation effect is provided by means of the at least one strip display as the virtual image. In other words, the at least one strip display is controlled in such a way that as the virtual image the dynamic running light is created. For this purpose, subsequent light sources of the at least one strip display can be controlled in at least one direction in order to create the impression that the virtual image is moving in at least one direction. This results in the advantage that the dynamic running light draws the occupant's attention to a particularly high level, and the occupant's attention can thereby be drawn particularly efficiently to a critical situation. Alternatively or additionally, the static light stripe can be output as the virtual image. The generated virtual image is thus a line-shaped light strip. This results in the advantage that a line shape focuses the occupant's gaze and, as a design element, creates an impression of interior equipment of the motor vehicle. A setting process, a setting made for a control parameter and/or a remaining ratio of a storage capacity to a total storage capacity is displayed by means of the dynamic running light and alternatively or additionally the static light strip. In other words, the virtual image is used to optically simulate the setting process, for example an attempted connection setup by a mobile terminal device to set up a communication connection with a person outside the motor vehicle or an acceleration process to reach a self-set target speed. As an alternative or in addition, the set control parameter is output based on the virtual image, for example an intended steering operation announced by actuating a direction indicator or its use as a hazard warning system. Alternatively or additionally, a capacity ratio is also displayed as the virtual image, with a current state of charge, i.e. the storage capacity in relation to the total storage capacity, of the mobile terminal device coupled to the motor vehicle being displayed or a fuel display (e.g. a fuel display, an oil level display) being implemented can be. Furthermore, it is advantageous that the virtual image can be recognizable for each vehicle occupant from a respective seating position in a vehicle interior compared to a conventional head-up display (HUD or head-up display). Thus, for example, the same image content can be perceived by a driver and a passenger using the virtual image, with a distortion of the virtual image being dependent on a viewing position.

The invention also includes embodiments that result in additional advantages.

A further advantageous embodiment provides that the at least one image source additionally has an at least two-dimensionally switchable image display, which is set up to generate a virtual image assigned to the at least one image display by selectively controlling pixels forming the at least one image display by the control device. In other words, the at least one image source also has an electrically controllable flat display, by means of which optical signals can be generated. This can be a screen, for example as a field emission screen (FED), as a liquid crystal screen (LCD), in particular a thin film transistor screen (TFT-LCD), a cathode ray tube screen (CRT), as a plasma screen, as an organic light emitting diode screen (OLED) or as a surface conduction electron emitter display (SED). Alternatively or additionally, the screen can include an LED backlight in the form of at least one mini-LED or an arrangement of at least one micro-LED. The at least one image display can, for example, output a surface (a two-dimensional object) and/or a body (a three-dimensional object). This results in the advantage that, if required, for example if a required information content can only be displayed incompletely by the at least one strip display, the information content can be output completely by means of the at least one image display.

A further advantageous embodiment of this provides that the at least one image display covers the at least one strip display in the direction of the reflection area. In other words, the at least one image display is superimposed on the at least one strip display, so that the at least one image display is arranged between the reflection area and the at least one strip display. Alternatively or additionally, the at least one strip display is interrupted in the area of the at least one image display and borders on two opposite sides of the at least one image display if the at least one strip display is arranged within an image plane formed by the at least one image display. In other words, the at least one image display and the at least one strip display are located in one plane, with the at least one image display being surrounded by the at least one interrupted strip display on the two opposite sides. Alternatively or additionally, the at least one image display and the at least one strip display are arranged without overlapping in relation to one another in the direction of the reflection area. The two displays that are different from one another are thus arranged next to one another in the direction of the reflection area, without one of the displays covering the other display, ie overlaying it. Wherein is the Installation position of the windshield the at least one strip display between the at least one image display and the side edge of the at least one pane layer comprising the reflection area and/or the at least one image display between the at least one strip display and the at least one pane layer comprising the reflection area. Thus, the two displays and the reflection area form a sandwich-like structure. Depending on the type of arrangement, the at least one strip display or the at least one image display is delimited on one side by the reflection area and on the other side by the display deviating from it. This results in the advantage that a large number of display options can be realized by means of a flexible arrangement of the two displays.

A further advantageous embodiment provides that the reflection area forms an optically continuous display surface which is bordered laterally by at least one of the A-pillars of the motor vehicle adjoining the windshield and/or is delimited by at least one digital display of a side mirror. In other words, the virtual image is displayed over a large area by means of the reflection area, with the optically continuous display area extending from one of the A pillars on a driver's side to the other of the A pillars on a passenger's side. Alternatively or additionally, the at least one digital display of the side mirror is arranged on at least one end of the optically continuous display surface. This results in the advantage that information can be displayed in a vehicle occupant's entire field of vision, with the occupant's gaze still being able to rest on a section of road to be driven on. At least one of the A-pillars and/or at least one of the digital display of the side mirror can be used as the respective lateral delimitation of the optically continuous display surface. Alternatively or additionally, the view of the occupant can be guided through the display area from a center of the display area to one side of the display area using the virtual image if a critical situation is identified based on a detected environment of the motor vehicle. The critical situation can be, for example, an unexpected overtaking maneuver by another motor vehicle that is located in a blind spot for the occupant.

A further advantageous embodiment provides that the control device, when activating the at least one image source, takes into account a position and/or orientation of a vehicle user detected by a detection device, in particular his head and/or eyes, and/or a detected user preference. Thus, the vehicle user himself and alternatively also the user preference entered by him are recorded in order to control the at least one image source depending on this. For example, the detection device includes a camera, in particular a driver observation camera, which detects data that describes the position and/or orientation of the head and/or the eyes of the vehicle user. A location of the motor vehicle user, ie the position in a room, the room comprising an interior of the motor vehicle, can then be determined on the basis of the recorded data. Alternatively or additionally, a position of the vehicle user, ie the orientation in space, can be determined based on the recorded data. Alternatively or additionally, the activation of the at least one image source can be dependent on the recorded user preference. In this context, the user preference is understood as an input initiated by the vehicle user that defines the respective output parameters, for example a display intensity, a display duration, a display color, a relative position and/or a relative location of the virtual image in relation to the vehicle user. Based on the detected vehicle user and/or the detected user preference, the virtual image is shifted along at least one spatial axis specified by a vehicle direction in order to generate a display that is free of occlusion in relation to the vehicle user. In other words, the virtual image is shifted along the at least one spatial axis, so that the vehicle user always has a direct and unrestricted view of the virtual image. Thus, for example, a size difference between two different vehicle users can be taken into account in the display. This results in the advantage that the display can be adapted as a function of the vehicle user, that is to say his physique and/or his movement and/or his preferred display settings. Alternatively or additionally, a perspective display can be implemented and thus a spatial effect can be generated, for example.

A further advantageous embodiment provides that the at least one strip display comprises at least two individual strips positioned next to one another. In other words, there are two individual strips arranged next to one another, which form the at least one strip display. In this case, a respective longitudinal extension axis of each of the at least two individual strips is arranged in a plane oriented correspondingly to the reflection area. This level is specified, for example, by a specific distance of the virtual image from the viewer in the longitudinal direction of the vehicle as a function of the reflection area. Within this level, the at least two Individual strips positioned in such a way that a respective axis of the respective individual strip, which corresponds to a respective direction of a respective greatest extent, lie in the plane. To generate the virtual image associated with the at least one strip display, only one of the at least two individual strips is to be activated in each case. As a result, the virtual image can be changed by means of selective activation of the respective individual strips, for example in order to shift the virtual image in a vertical direction of the vehicle, with the specific distance of the virtual image from the occupant being able to be kept constant. This results in the advantage that a position of the light strip and/or the running light can be changed particularly easily, with complex display technology, in particular that of a screen, being able to be dispensed with.

A further advantageous embodiment provides that the at least one strip display is arranged on an actuator which can be controlled by the control device and is set up to change a relative position of the at least one strip display to the reflection area in order to shift the virtual image. In other words, the at least one strip display can be spatially displaced by means of the actuator, a relative position of the at least one strip display in relation to the reflection area being changed depending on a displacement of the at least one strip display. The actuator is, in particular, a technical drive unit that can convert an electrical control signal from the control device into a mechanical movement. Here, the actuator can be designed, for example, as a frame with a movable arm, with a scissor construction or a vertical mast. This results in the advantage that the at least one strip display can be used in a particularly variable manner and the number of LED strips used and installed can thus be reduced.

Provision is made for the reflection area to have at least one surface section which can be switched by the control device from a transparent to at least a partially opaque and partially black-colored state for generating the virtual image. The at least one surface section is thus selectively actuated in order to specify transparency and/or blackening of the at least one surface section. In particular, a corresponding gradient, for example a tint gradient, can be generated. This results in the advantage that the at least one surface section can be used for different purposes. Thus, the at least one surface section can be used in the at least partially opaque and partially black-colored state for generating the virtual image and in the transparent state for undisturbed observation of a vehicle environment by the occupant.

A further advantageous embodiment of this provides that the at least one permanently opaque and black-colored surface section comprises a screen-printed edge. Thus, the at least one surface section, which is always opaque and black, comprises a screen-printed border. The screen-printed edge, that is, a so-called black print, can be formed, for example, as a black disk edge that has a solid black section and a dotted section. In this case, the screen-printed edge has several reflection particles. That is to say, the screen-printed edge comprises particles which are designed to reflect the light rays emitted by the at least one light source. This results in the advantage that the screen-printed edge can be used as a background for the virtual image and an area occupied by this can be used to generate the virtual image. Alternatively or additionally, the at least one switchable surface section is formed from an electrochromic, thermochromic and/or liquid-crystal-based material. In other words, the at least one switchable surface section comprises the electrochromic, photochromic, thermochromic and/or liquid-crystal-based material. These are, in particular, materials that are designed to produce tintable glazing, in that light transmission can be changed by applying an electrical voltage, changing lighting conditions and/or as a reaction to heating. Tungsten trioxide or polyaniline, for example, is used as the electrochromic material, vanadium dioxide, for example, is used as the thermochromic material, and the photochromic material includes, for example, halogens or nitrates. The material based on liquid crystals is, for example, an LC glass (liquid crystal) or a PDLC glass (polymer dispersed liquid crystal).

If necessary, a method for operating an embodiment of a motor vehicle according to the invention can be implemented with a display system, the motor vehicle comprising a windshield with at least one pane layer, at least one image source, a reflection area and a control device. The control device has, for example, a processor device that includes at least one microprocessor, at least one microcontroller, at least one FPGA (Field Programmable Gate Array) and/or at least one DSP (Digital Signal Processor). Furthermore, the processor device can have a program code that is in a Data memory of the processor device can be stored and is set up to carry out the method when executed by the processor device. The at least one image source is positioned in a dashboard of the motor vehicle and optionally provides an exclusively one-dimensionally switchable strip display, the at least one strip display in the dashboard parallel to a side edge of the at least one layer of panes and/or at least one of the at least one layer of panes, which is predetermined by a radius of curvature separate component is positioned. Furthermore, the reflection area extends parallel to a side edge of the at least one pane layer and is arranged on the dashboard in an installation position of the windscreen in the motor vehicle, the reflection area along at least one side area of the at least one pane layer on at least one pane surface and/or along the at least one Component is provided on a windshield frame. The method may include detecting an adjustment process and/or an adjustment made to a control parameter and/or a remaining ratio of the storage capacity to a total storage capacity. Light beams are then emitted by the at least one image source depending on the detection, the at least one image source being controlled by the control device, and the emitted light beams reflected by the reflection area to generate a virtual image. For example, a dynamic running light for generating an animation effect and/or a static strip of light for displaying the adjustment process and/or the adjustment made to the control parameter and/or the remaining ratio of the storage capacity to a total storage capacity is provided as the virtual image.

The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle.

The motor vehicle 10 may further include a windshield 16 which may have a lens layer 18 . In particular, the windshield 16 can be designed as a laminated glass pane and have a plurality of respective pane layers 18 arranged one on top of the other. The pane layer 18 can be delimited by two pane surfaces 20', 20" and a side edge 22, in particular four side edges 22. For this purpose, one pane surface 20' can face an interior 24 of the motor vehicle 10 and another pane surface 20' can face an area 26 of the motor vehicle 10 In an installation position of the windshield 16, the side edge 22 can be arranged via a windshield frame 28 on the motor vehicle 10, in particular between two A-pillars 30', 30" and respective side mirrors 32', 32" or on a dashboard 34, with 1 only the A-pillar 30' visible in the illustration and the side mirror 32'' are provided with a respective reference number.

Furthermore, this can 1 Motor vehicle 10 shown--each shown in simplified form as a box--have a control device 36, a detection device 38 and an image source 40. In this case, the control device 36 can control the image source 40 as a function of data acquired with the acquisition device 38 . The detection device 38 can detect a head and eyes of the vehicle user 14 in particular as a driver observation camera, using which a position and an orientation of the vehicle user 14 can be determined by the control device 36 . Furthermore, the detection device 38 can be used in particular as one, for example in 4 and 5 shown user interface 47, be designed to capture a user preference, that is, an input of the vehicle user 14 can. The image source 40 is discussed below in connection with 2 and 3 described in detail.

Motor vehicle 10 with display system 12 is in 2 and 3 further elaborated. while showing 2 a schematic representation of a section of the motor vehicle 10 with the display system 12 in a plan view and 3 a corresponding sectional view AA with respective components associated with 1 have already been described. 2 thus shows the pane surfaces 20" of the windshield 16 facing the surroundings 26, which adjoin the two A-pillars 30', 30" and an upper side of the dashboard 34, a steering wheel 45 being arranged on the dashboard 34.

In 2 and 3 a possible embodiment of the image source 40 is shown as an example. In this case, the image source 40 can comprise, for example, a plurality of electrical light sources, respective displays 42, 50', 50", 50", which are set up to emit light beams S1, which are shown as arrows in 3 are shown. The image source 40 can have an exclusively one-dimensionally switchable strip display 42, which is in the dashboard 34 parallel to the side edge 22 specified by a radius of curvature 44 and alternatively to a component 46 specified by a radius of curvature 44 that is separate from the pane layer 18. In particular, the strip display 42 can be an individual strip 48', 48'' designed as an LED strip. Here—as shown for the individual strip 48'', the strip display 42 can be arranged in a fixed position in the dashboard 34. It is also possible for the individual strip 48" of the strip display 42 to be arranged on an actuator 53 that can be controlled by the control device 36, by means of which a relative position P1, P2 of the strip display 42 can be changed, as indicated by an arrow the arrow indicates only one possible direction of movement of the actuator 53.

In the 2 and 3 The image source 40 shown can additionally have a two-dimensionally switchable image display 50, three individual image displays 51′, 51″, 51′″ being shown as screens in the present case. A relative arrangement of the image display 50 and the strip display 42 can be configured variably. The strip display 42 comprising the individual strip 48" can be interrupted in the area of the image display 50, as shown for the single image display 51`, and can adjoin the image display 50 on two opposite sides 52`, 52" if the strip display 42 is within one of the Image display 50 formed display level E1 is arranged. The image display 50, as shown for the single image display 51', can also cover the strip display 42, which includes the individual strip 48', in the direction of the windshield 16. This would be the case if a position-variable arrangement by means of the actuator 53 were dispensed with and the individual strip were permanently arranged at the relative position P1. In this case, the two individual strips 48', 48" of the strip display 42 would be positioned next to one another, with a respective longitudinal axis A1, A2 of each of the individual strips 48', 48" being arranged in a common plane E2, with only one of the two individual strips 48` , 48" is to be actuated by means of the control device 36. In 3 For example, the display level E1 and the level E2 are congruent. Furthermore, it may be possible to arrange the image display 50 and the strip display 42 without overlapping one another, so that in the installation position of the windshield 16 the strip display 42 is between the image display 50 and the side edge 22 of the window layer 18 or the image display 50 is between the strip display 42 and the side edge 22 of the disk layer 18, such an arrangement not being shown for the sake of clarity.

In 3 also shows how to reflect the light beams S1 emitted by the image source 40 to generate a virtual image 54`, 54" at a reflection area 58 as reflected light beams S2. The virtual image 54` corresponds to the individual strip 48` of the strip display 42 in the respective relative position P1, P2 and the virtual image 54" with the individual strip 48" of the strip display 42. The virtual image 56 assigned to the image display 50 is generated by the control device 36 by selectively driving pixels forming the image display 50. The reflection area 58 can extend parallel to a side edge 22 of the disc layer 18, the reflection region 58 along a side region 61 of the disc layer 18 at one of Pane surfaces 20 ', 20 "is provided. Alternatively or additionally, the reflection area 58 can be provided along the component 46 that is separate from the pane layer 18 on the windshield frame 28, with a representation having been omitted for the sake of clarity. The reflection area 58 forms an optically continuous Display area 60, the in 4 and 5 is shown in detail, which is bordered laterally by the A-pillars 30', 30" of the motor vehicle 10 and can be delimited by a digital display 62`, 62" of the side mirror 32`, 32", the digital display 62`, 62"" than covered by the respective A-pillar 30', 30" in 3 is indicated schematically.

The image source 40 can be controlled by means of the control device 36 . Depending on the data recorded with the recording device 38, the virtual image 54`, 54" of the strip display 42 and/or the virtual image 56 of the image display 50 along a vertical axis, designated as the x-axis, and a transverse axis, designated as the y-axis, of the Motor vehicle 10 to be relocated in order to generate an unobscured display in relation to the vehicle user 14. Also, only one of the two individual strips 48', 48" can be controlled to generate the virtual image 54', 54" associated with the strip display 42. Des Furthermore, the relative position P1, P2 of the individual strip 48` of the strip display 42 to the reflection area 58 can be changed in order to shift the virtual image 54'.

4 and 5 each show a different design of the reflection area 58 and the virtual image 54', 54", 56' with respective components that are associated with 1 , 2 and 3 have already been described. The perspective illustrations shown show the interior 24 of the motor vehicle 10 with the display system 12 in two embodiments, with a viewing direction through a windshield 16 corresponding to a forward movement direction of the motor vehicle 10 . The reflection area 58 can have two surface sections 64`, 64". For this purpose, the surface section 64` can be permanently opaque and colored black and the surface section 64" can be switched from a transparent to at least a partially opaque and partially black-colored state by means of the control device 36 in order to generate the virtual image 54', 54'', 56 are switched. The one permanently opaque and black-colored surface section 64` can - as in 4 shown - include a screen printed border 66 having a plurality of reflective particles. 5 shows the switchable surface section 64", which is formed, for example, from a material based on liquid crystals. Thus, for example, a tint or a color gradient can be implemented by means of the switchable surface section 64".

In 4 the display area 60 can be displayed as the virtual image 54', 54", 56 of the strip display 42 for displaying a setting made for a control parameter, for example actuating a direction indicator 65. A dynamic running light 68' can display an animation effect for displaying a selected direction of travel and a static light stripe 68" indicate a direction of travel that differs from the selected direction of travel. In addition, an arrow symbol 70 showing the selected direction of travel can be displayed by means of the image display 50 . Furthermore, a remaining ratio of a storage capacity to a total storage capacity, for example as an available fuel supply, or an adjustment process, for example increasing a current speed to a maximum permissible speed, can be displayed. In this case, a redundant display by means of an instrument cluster can be dispensed with, or the attention of the vehicle user 14 can be controlled in a targeted manner due to the redundant display.

To generate the virtual image 54`, 54", 56, in a first step V1 the adjustment process, the adjustment made to the control parameter and a storage ratio are recorded, by means of which these can be provided as data by the recording device 38 to the control device 36. Subsequently, in a second step V2 depending on the detection, i.e. based on the detected data, the light beams S1 are emitted by means of the image source 40, the image source 40 being controlled for this purpose by the control device 36. The emitted light beams S1 are in a third step V3 by means of the reflection area 58 and generate the virtual image 54', 54", 56 as reflected light beams S2, in particular as a dynamic running light 68` and as a static light stripe 68".

The invention is based on the recognition that an application of a black print, ie a black area formed by the screen-printed edge 66, normally remains unused. This can be used for an at least two-dimensional display as a display surface 60 that appears optically continuous. For example, symbols that describe a warning or infotainment content of an instrument cluster or a virtual assistant can be displayed. Optionally, a three-dimensional impression of the display can be achieved through the use of a dynamic perspective that continuously rotates the vehicle user's 14 head or eyes detected (head or eye tracking) and a perspective of the virtual image 54 ', 54'', 56 adjusts. Thus, warning symbols can be displayed dynamically in a viewing direction of the driver (vehicle user 14). Furthermore, the visual display content in the instrument cluster can also be reduced and information can be displayed in the driver's field of vision (vehicle user 14) in front of the stationary and monochromatic background (reflection area 58). The image source 40 can reflect in particular in the black area at a pane root (side edge 22 of the windshield 16), with the image source 40 being able to have the strip display 42 and the image displays 50. A particularly high contrast value can thus be implemented in the display, giving the impression that the black area itself is the strip display 42 or the image display 50 .

Overall, the examples show how the invention can provide a column-to-column display (pillar-to-pillar display) by reflecting into the black area (reflection area 58) of the pane (windshield 16).
