Description

The invention relates to a motor vehicle having a front window, a dashboard and a display device, the display device having a HUD module with a housing and the display device having a first display area for displaying information against a transparent background. The invention also relates to a HUD module.

To display information for a driver, a motor vehicle usually has a so-called combination instrument, which is typically inserted in a so-called dashboard. In addition, a motor vehicle often has a display screen which is usually positioned in the area of the so-called center console or in a central area of the dashboard. In addition, so-called head-up displays, such as those in the DE 10 2016 003 430 A1 are described.

The object of the present invention is to create an advantageously designed motor vehicle and an advantageously designed HUD module.

This object is achieved by a motor vehicle with the features of claim 1 and by a HUD module with the features of claim 10. The advantages and preferred refinements cited with regard to the motor vehicle can also be applied to the HUD module and vice versa. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.

The motor vehicle according to the invention has a front window or windshield and a so-called dashboard, which is also referred to as a dashboard or instrument panel. The motor vehicle also has a display device, the display device having a head-up display module or HUD module for short with a housing. The motor vehicle and in particular the display device is designed and set up in such a way that it has a first display area for displaying information in front of a transparent or at least approximately transparent background and a second display area for displaying information in front of an opaque or non-transparent background. The opaque or non-transparent background is formed by a display unit which has the HUD module, which is therefore part of the HUD module.

An embodiment is preferred here in which the display unit forms a dark, for example dark gray, and in particular black background as an opaque background, in which the opaque or non-transparent background is in particular formed as a black background.

Depending on the application, no so-called combination instrument is then installed in the motor vehicle. The classic instrument cluster is therefore preferably omitted. Instead, the information that is usually displayed by such an instrument cluster is displayed by the display device and in particular by the display unit. The corresponding information is thus displayed in the first display area and / or in the second display area. The display device and in particular the display unit then replace the combination instrument.

It is also useful if the display unit is molded or attached to the housing of the HUD module. That HUD module is typically prefabricated and installed as part of a final assembly. The dashboard typically has a receptacle, for example a type of trough or recess, for the HUD module, into which the HUD module is inserted during final assembly.

It is also advantageous if the HUD module has a so-called mirror bank. A corresponding mirror bench is, for example, in the DE 10 2016 003 430 A1 and typically molded or attached to the housing of the HUD module. The mirror bench and / or the housing of the HUD module are preferably configured in accordance with one of FIG DE 10 2016 003 430 A1 described embodiment and therefore reference is expressly made at this point to the explanations in the DE 10 2016 003 430 A1 .

An embodiment of the HUD module in which the display unit is molded onto or attached to the mirror bench described above is also considered to be advantageous and furthermore. Particularly advantageous here is a design in which the display unit sits on top of the mirror bench or in which the mirror bench is designed to be extended, in particular extended into the so-called viewing area or upward, and in which this extension is used as a holder for the display unit acts.

Furthermore, the housing of the HUD module is typically arranged sunk in the dashboard. The fitting support usually has a receptacle, for example a type of trough or recess in which the housing rests. However, the display unit and / or the mirror bench preferably protrude at least partially or out of the recess or receptacle. That means that the Instrument carrier, for example, has a recess as a receptacle for the HUD module, that the housing rests in this recess after positioning in the receptacle and is thus arranged sunk in the dashboard and that the display unit and / or the mirror bench protrude at least partially from this recess and thus at least are partially arranged outside of the recess or receptacle.

The display unit further preferably projects completely out of this recess and is thereby positioned completely outside the recess or receptacle. Irrespective of this, it is typically in the so-called field of vision of a driver of the motor vehicle or protrudes into the field of vision. This means that the display unit is visible to a driver.

Depending on the application, a screen element also forms the display unit. In this case, the motor vehicle and in particular the display device is designed and set up in such a way that an image can be projected onto the screen element in order to display information in the second display area.

Alternatively, a display forms the display unit. In this case, the display unit is then designed, for example, as a so-called LCD display, as a so-called OLED display or something similar. That display is part of the HUD module and is therefore controlled, for example, during operation via electronics in the HUD module.

Regardless of the configuration of the display unit, the front panel preferably forms the transparent background. Accordingly, the motor vehicle and in particular the display device is then designed and set up in such a way that an image can be projected onto the windshield to display information in the first display area and, if necessary, is projected.

Further advantages, features and details of the invention emerge from the claims, the following description of preferred embodiments and on the basis of the schematic drawings. Show:

• 1 a detail from a sectional view of a motor vehicle with a display device;
• 2 an enlarged sectional view of a first embodiment of the display device; and
• 3 an enlarged sectional view of a second embodiment of the display device.

A motor vehicle described below as an example 2 has a windshield 4th , a so-called dashboard 6th and a display device 8th on.

Part of the display device 8th is in the exemplary embodiment a head-up display module or a HUD module for short 10 , which is usually in a recording 12th , typically a kind of trough or recess, in the dashboard 6th is positioned. There is a housing 14th of the HUD module 10 preferred in the recording 12th in the dashboard 6th sunk arranged and a top 16 of the housing 14th is towards the windshield 4th of the motor vehicle 2 aligned.

The car 2 and in particular the display device 8th is now designed and set up in the exemplary embodiment in such a way that the display device 8th a first display area 18th for displaying information against a transparent background. This forms the front pane 4th of the motor vehicle 2 the transparent background and the HUD module 10 is designed and set up, if necessary for the purpose of displaying information, an image on the windshield 4th to project.

The corresponding image projection is then reflected in the direction of a driver's seat, which is not explicitly shown, so that a driver 20th that on the windshield 4th projected image can see, whereby this the information obtained in the image are displayed. According to the principle that is known per se, the driver takes 20th that on the windshield 4th projected image positioned at a virtual image position 22nd outside the vehicle 2 true.

To now the previously described projection of an image onto the windshield 4th to enable, assigns the HUD module 10 in the exemplary embodiment a first integrated display 24 on, so a display, which is in the housing 14th of the HUD module 10 is housed. With the help of this first integrated display 24 , which is designed, for example, as a so-called LCD display or as a so-called OLED display, an image is generated if necessary, which is then usually applied to the front pane by means of an optical device 4th is projected. In the exemplary embodiment, the optical device has, for example, two mirrors 26th on, of which, for example, one is fixed and one is movably mounted so that it can be aligned.

The projection of a corresponding image onto the windshield 4th takes place according to a principle known per se through the top 16 of the housing 14th of the HUD module 10 which for this purpose is designed to be transparent in at least one area. To avoid unwanted reflections, especially from ambient light on the top 16 of the HUD module 10 towards the windshield 4th to avoid or reduce, instructs the HUD module 10 in the exemplary embodiment further a so-called mirror bench 28 on.

This is typically a type of panel, for example made of plastic, which is attached to the housing, for example 14th of the HUD module 10 molded or on the housing 14th is attached and which is expediently designed from the top 16 of the housing 14th of the HUD module 10 absorb reflected light. In the exemplary embodiment is the mirror bench 28 designed matt black for this purpose.

An embodiment in which the mirror bench is also typical is typical 28 at least partially from the recording 12th in the dashboard 6th protrudes. The mirror bench 28 also usually extends in a transverse direction from one of the so-called A-pillars of the motor vehicle 2 to the other A-pillar of the vehicle 2 and is, for example, strip-shaped. The mirror bench extends further 28 typically in an upstanding direction 30th transverse to the transverse direction, the upright direction 32 from the dashboard 6th towards the roof 32 or headliner of the motor vehicle 2 shows. The extension of the mirror bench 28 in a rising direction 30th is typically in the range 40 mm to 80 mm and in particular in the range 50 mm to 60 mm.

In addition to the first display area 18th instructs the display device 8th in the exemplary embodiment a second display area 34 to display information in front of an opaque and in particular black background. This is what the HUD module 10 a display unit which forms the opaque or black background.

In the embodiment according to 2 is the display unit as a screen element 36 designed, so as a kind of screen on which an image is projected if necessary, which then in turn in the direction of the aforementioned driver's seat and possibly in the direction of the driver 20th is reflected. A corresponding screen element 36 preferably has a glossy black surface.

Next is in the embodiment according to 2 the screen element 36 at the mirror bench 28 attached or molded or in a protruding direction 30th on the mirror bench 28 put on. Here is the screen element 36 depending on the application, for example with the help of a type of strip or panel, for example made of plastic, which is coated, for example, in at least one area for the benefit of good reflectivity.

According to an embodiment variant, a single panel or bar forms both the mirror bench 28 as well as the screen element 36 from, wherein the screen is made, for example, of plastic and, for example, in an area for forming the screen element 36 is coated with a first coating and in another area to form the mirror bench 28 coated or uncoated with a second coating. Alternatively, the panel has different surfaces in the two corresponding areas, for example a rough surface to form the mirror bench 28 and a smooth surface for forming the screen member 36 .

Regardless of this, the screen element 36 in a rising direction 30th usually an extension in the range 40 mm to 80 mm and in particular in the range 50 mm to 60 mm. An extension in the transverse direction in the range of 200 mm to 300 mm is also typical. The mirror bench 28 regardless of this, usually has an extension in the transverse direction in the range in the range from 200 mm to 300 mm.

To now, if necessary, a picture on the screen element 36 to project, assigns the HUD module 10 according to one embodiment variant, a second integrated display 38 on, i.e. a second display, which is in the housing 14th of the HUD module 10 is arranged. Alternatively, the HUD module 10 just an integrated display to show an image in the first display area 18th and to project an image into the second display area 34 to project. In this case, the HUD module 10 then typically an adapted optical device.

The motor vehicle is independent of this 2 and in particular the display device 8th designed and set up in such a way that information is displayed simultaneously in the first display area 18th and information in the second display area 34 can be displayed.

Another variant of the display device 8th is in 3 shown. Here the display unit is not a screen element 36 designed but as a display 40 , for example as an LCD display or as an OLED display. The dimensions of the display 40 , the position of the display 40 and the orientation of the display 40 preferably correspond to those of the screen element described above 36 , just the thickness of the display 40 is usually different.
