Description

Technical Field

[0001] This invention relates to a head-up display (HUD) for motor vehicles or other road, air, or water vehicles. The HUD includes an imaging display surface disposed on the upper side of the vehicle's dashboard and extending along the windshield in the lateral direction of the vehicle, so that vehicle occupants, such as the driver or front passenger, see a reflected display surface (virtual image) when looking at the lower section of the windshield. The invention also relates to a vehicle equipped with said HUD. Background Technology

[0002] Using a HUD, also known as a panoramic HUD (PHUD), one wants to present a continuous virtual image (including entertainment, communication, or navigation content) or image content relevant to the vehicle or driver to the driver or front passenger. This virtual image, in particular, should extend as far as possible across the entire width of the windshield, i.e., in the lateral direction of the vehicle, like a panoramic image. For this purpose, the display surface of the image must extend accordingly along the windshield.

[0003] The PHUD display can display different graphic objects arranged side-by-side across the width of the PHUD. Currently, the arrangement of information and display objects is fixed and offers virtually no personalization in terms of appearance, i.e., the arrangement and selection of display objects across the width of the PHUD. Summary of the Invention

[0004] The objective of this invention is to provide an improved display system with a PHUD display that enables the configuration of display objects across the width of the PHUD display in a personalized manner.

[0005] The task is accomplished by a display system having a PHUD display according to claim 1 and by a method for configuring a PHUD display according to the co-claims.

[0006] Other embodiments are given in the dependent claims.

[0007] According to the first aspect, a display system for a vehicle is provided, the display system comprising:

[0008] A PHUD display with a display device, wherein the displayed image is perceptible to the user through reflection on the display surface, and the arrangement and selection of display objects can be configured and represented on the display surface in corresponding display areas;

[0009] An operating device having a display unit and an input unit for performing operation input;

[0010] The control unit is configured to display an icon of a display object on a display unit and to assign the icon of the display object to or remove it from the display area of ​​the display surface by means of an operation input using an input unit, so as to define configuration settings.

[0011] It can be specified that the operating device is configured to assign the display object assigned to the display object icon to the display area of ​​the display surface of the PHUD display by virtually moving the display object icon represented on the display unit in the configuration mode, so as to output or display there.

[0012] The display object may be, for example, a text representation, a symbol representation, or a graphic representation, where the text representation, the symbol representation, or the graphic representation is the output of a function implemented in the vehicle. Thus, the display object may include:

[0013] The display of vehicle-related information, such as speed indicator, engine temperature indicator, etc.

[0014] Indications related to the driver, such as fatigue level, etc.

[0015] The display of entertainment functions, such as the title and album art of the music being played, the name and logo of the radio station, volume display, video display of movies, and image display.

[0016] Navigation features include directional arrows, lane displays, map representations, and an input screen window for destination input.

[0017] The output of communication functions is represented, such as call lists, text messages, icons for connecting to mobile devices along with corresponding signal strength, mobile device battery status, etc.

[0018] The representation of output from third-party functions or third-party applications (Apps) implemented in the vehicle system, such as weather indicators, social media functions, smart home functions, etc.

[0019] The display of the screen content of the mobile device, thereby mirroring or transmitting the screen content of the mobile device onto the display area of ​​the display object.

[0020] The display objects can be provided in the form of so-called widgets, each widget defining a display area in which the associated display object is represented or output as the output of vehicle functions.

[0021] The width of the perceptible display surface generally follows the width of the windshield, and in particular corresponds to at least 80% of the width of the windshield.

[0022] The operating device allows for the allocation of corresponding display objects to areas of the PHUD display's screen surface in configuration mode for output or representation there. This enables personalized configuration of the arrangement, selection, and order of display objects on the PHUD display's screen surface.

[0023] Display objects that are not allowed to be displayed during driving, such as video displays, can be gradually faded or dimmed during driving so that the display objects do not distract the driver from driving the vehicle.

[0024] The operating device may have a touchscreen that includes a combination of a display unit and an input unit.

[0025] It can be specified that the control unit is configured to define or select configuration settings via touchscreen operation gestures "click", "drag" and "release", wherein the display object icons can move between a pool of display objects with multiple selectable display object icons and a configuration bar, wherein the arrangement of the display object icons in the configuration bar indicates the position and selection of the display objects on the display surface.

[0026] The operating device may include at least one input unit and at least one display unit (screen), and for example, a touch screen with combined display unit and input unit (touch functionality) included in the center console or as part of a vehicle assistance system.

[0027] In configuration mode, a reduced representation of the side-by-side display areas can be symbolically indicated in the configuration bar, for example as an empty frame or an icon, which identifies the display object assigned to that display area.

[0028] In the display object pool represented on the display unit, the area of ​​the display unit represents multiple display object icons, each of which represents a display object to be represented.

[0029] By operating the input unit, for example by clicking the display object icon and "dragging" the display object icon to the corresponding display area of ​​the configuration bar, the display object can be assigned to a specific display area of ​​the display surface. The order of the display object icons on the display unit corresponds to the order and arrangement of the display objects on the display surface of the PHUD display.

[0030] Display object icons can be removed from the display surface by clicking to select the display object icon from the configuration bar, and then "dragging" and "releasing" the display object icon from the configuration bar, specifically to the trash can icon. These "dragging" and "releasing" are typical touchscreen operation gestures where a finger moves along or lifts off the screen surface. Alternatively, the display object can be removed from the configuration bar by clicking the "remove" icon on the corresponding display object, such as "-" or "x".

[0031] Display objects can be moved within the display surface by clicking and holding the relevant display object icon and dragging it to another area of ​​the configuration bar. The corresponding display object icon is "released" from the touchscreen within the display area of ​​the configuration bar, corresponding to the display area of ​​the PHUD display's screen.

[0032] To map the entire width of the display surface onto the configuration bar, the configuration bar can be selected in segments using input units, such as "left side," "middle," and "right side." This allows the configuration bar to represent display objects on the upper left, middle, or right side of the display surface and to be assigned to the corresponding display objects. When, for example, the left side segment is not configurable, fewer segments can be considered, such as only "middle" and "right side."

[0033] In configuration mode, once the display object icon has been assigned to the display area of ​​the configuration bar, the configuration of the display object and the display area of ​​the display surface can be made visible directly in the display surface.

[0034] It can be specified that the control unit is configured to display a selection element on the display unit, wherein the display object is displayed according to a determined predefined configuration setting by operating the selection element. Attached Figure Description

[0035] The various implementation methods are further illustrated below with the aid of the accompanying drawings. In the drawings:

[0036] Figure 1 A schematic diagram showing a vehicle equipped with a PHUD display and a touchscreen as an operating device; and

[0037] Figures 2a to 2c A diagram is shown illustrating the operation of the operating device in a configuration mode for a PHUD display. Detailed Implementation

[0038] Figure 1A vehicle 1 with a PHUD display 2 is schematically shown, which is operable via a control unit 3. The PHUD display 2 includes a self-illuminating display device 4, which is planarly disposed on the upper side of a dashboard 5. The display surface 6 of the PHUD display 4 has a width that substantially corresponds to the width of the windshield 9, but is at least 80% of the width of the windshield 9.

[0039] The display device is positioned near the lower edge of the windshield 9, so that the displayed image can be perceived by the driver through reflection on the lower region 7 (reflective surface) of the windshield 9. Therefore, the lower region 7 of the windshield 9 is preferably configured as a black printed area, i.e., an opaque area.

[0040] The display surface of the display device can represent display objects, which are presented as text symbols or graphics and are outputs of functions implemented in the vehicle. This allows for the representation of the following types of display objects:

[0041] The display of vehicle-related information, such as speed indicator, engine temperature indicator, etc.

[0042] Indications related to the driver, such as fatigue level, etc.

[0043] The display of entertainment functions, such as the title of the music being played, the name of the radio station, the volume, and the video and image representation of movies.

[0044] Navigation functionality is indicated by features such as directional arrows, map displays, and input screen windows for destination input.

[0045] The output of communication functions is represented, such as call lists, text messages, icons for connecting to mobile devices along with corresponding signal strength, mobile device battery status, etc.

[0046] The representation of the output of third-party functions or third-party applications implemented in the vehicle system, such as weather indicators, social media functions, smart home functions, etc.

[0047] The display of the screen content of the mobile device, thereby mirroring or transmitting the screen content of the mobile device onto the display area of ​​the display object.

[0048] Furthermore, the control unit 3 is connected to the operating device 8, which may correspond to, for example, a touchscreen of a vehicle assistance system, or be provided as a separate input option. Alternatively, the operating device may be a mobile device connected to the control unit 3 via a suitable interface.

[0049] Figures 2a to 2c This demonstrates the possibility of configuring the representation of displayed objects via the PHUD display 4. Figures 2a-2c The image shows a view from the driver's perspective inside the vehicle 1. The display surface 6 of the PHUD display 2, along with the displayed objects 61 and an operating device 8 having a display unit showing a configuration interface, includes a configuration bar 81 and a pool of display objects 82 with multiple display object icons 83. The configuration bar 81 represents a scaled-down representation of the structure of the display surface 6 or a scaled-down representation of the arrangement of the display objects on the display surface. Using the operating device 8, the configuration interface can be operated in configuration mode to individually position the display object icons 83 within areas of the display surface based on their arrangement in the configuration bar 81.

[0050] The display surface 6 is divided into display areas 62, where display objects, i.e., widgets, can be installed. Display object 61 is a graphical output of vehicle functions.

[0051] like Figure 2b As shown, the configuration bar, for example, uses an empty frame to indicate the position of the display area of ​​the display surface, and display objects or widgets can be configured for the display area.

[0052] Due to the large width of the display surface, a section of the display surface can be represented by a configuration bar, and the selection element 85 can be used to switch between the sections.

[0053] like Figure 2c As shown, by clicking the display object icon in the display object pool and dragging the display object icon to the corresponding area of ​​the configuration bar, the display object assigned to the display object icon can be positioned on the corresponding display area of ​​the display surface, which corresponds to the area within the configuration bar.

[0054] Similarly, the display object icon can be moved out of the corresponding area of ​​the configuration bar by clicking the display object icon and dragging it out of the area of ​​the configuration bar.

[0055] If you drag the relevant display object icon to another area of ​​the configuration bar, you can swap the display object icons assigned to the corresponding area and thus swap the display objects in the relevant assigned area of ​​the display surface.

[0056] This point is passed Figure 2c The arrow drawn in the middle is shown.

[0057] After each configuration action and / or after the end of configuration mode, the corresponding display object is displayed in the configured area on the display surface of the PHUD monitor.

[0058] However, objects that are not allowed to be displayed during driving are dimmed or blacked out to avoid unauthorized distractions for the driver.

[0059] Once the PHUD display is configured, the settings can be personalized for the user and automatically applied to the display when a specific driver is identified. Furthermore, selection elements can be displayed, allowing users to switch between different configuration settings for the display surface via clicks.
