Description

[0001] The invention relates to a vehicle display system, in particular for a motor vehicle.

[0002] Displays are playing an increasingly important role in motor vehicles, leading to a significant increase in their applications and sizes. Currently, displays, particularly in the dashboard or rear passenger compartment, are arranged two-dimensionally as so-called flat screens, side by side. This has the disadvantage of severely limiting the total display area, resulting in information that is either relatively small and therefore difficult to read, or incomplete. Furthermore, the adjacent passenger always has an unintentional view of the neighboring display. This applies equally to the driver and front passenger.

[0003] Vehicle display systems with multiple screens, which are also swivel-mounted, are known from the prior art. For example, German patent application DE102019126106 A1 discloses multiple screens that can be arranged or swiveled in different ways to display information individually on two screens or together on a combined screen formed by merging both screens. For this purpose, the two screens move along a respective path that allows collision-free movement. The screens can be combined into a single display unit in a merged position. However, this has the disadvantage that the rails and / or swivel arms require installation space, and the screens for displaying different information are comparatively small.

[0004] In contrast, US patent application US 2011 / 0006892 A1 discloses a concept for vehicle instrumentation that uses a flexible, contour-following display and control panel ("Bendable On-Demand Display"). This replaces static displays with flexible, dynamically adaptable displays that conform to the interior contours of the vehicle and provide individually configurable information to the vehicle occupants. In addition to classic operating data, telematics, entertainment, comfort, and safety functions can also be integrated. Through touch and voice control, wireless connectivity, and networked driver assistance functions, the dashboard becomes a central control and information platform. However, the solution shown in the aforementioned document has the disadvantage that the flexible display loses its shape due to vibrations and / or heat, generates noise, and wobbles, which can negatively affect the legibility of the displayed information.

[0005] The object of the present invention is to provide a vehicle display system which eliminates the disadvantages of the prior art described above.

[0006] This problem is solved by a vehicle display system having the features of independent claim 1. The dependent claims relate to advantageous further developments and variants of the invention.

[0007] A vehicle display system according to the invention for a motor vehicle with at least two displays is characterized in that the direction of projection of the content displayed on the displays is directed towards each occupant of the motor vehicle. This enables advantageous personalization of the information displayed on the screens. By using displays designed for at least two occupants, for example, the driver and the front passenger, the driver can receive information relevant to driving the motor vehicle, while the front passenger can, for example, use an additional infotainment system. Each occupant can, through this "spatial division," receive the information relevant to them or additionally selectable information. This has the advantage that the driver is not distracted by information (films) on a display that is also easily visible to the driver, as is currently the case with central displays.For example, a passenger can watch a movie without distracting the driver.

[0008] In addition, the vehicle display system can include at least one further secondary display, which can advantageously increase the area for displaying information.

[0009] Furthermore, at least one display and at least one secondary display can be combined to form a single, larger display. This allows for a significant increase in display size, enabling the presentation or magnification of the information itself and / or multiple pieces of information. In particular, the at least one display and the at least one secondary display can be seamlessly integrated. This can contribute to a superior viewing experience for the occupant.

[0010] In a further embodiment of the invention, the at least one secondary display can be arranged in a door of the motor vehicle. Alternatively, the at least one secondary display can be arranged in a center console of the motor vehicle. Alternatively, both arrangements can be used simultaneously.

[0011] In a further embodiment of the invention, a sensor can be provided to detect a connection between the secondary display and the main display when the door is closed. This can be achieved, in particular, by integrating the sensor into the vehicle structure, especially the opening and closing mechanism of the door(s).

[0012] In a further embodiment of the invention, at least one display can be curved, in particular concave. A concave design of the display increases personalization for the occupant sitting in front of the display. The available area is larger compared to a flat screen, and at least a partially wraparound view can be achieved, thus creating a wide viewing angle.

[0013] Furthermore, the entire display can be designed with an angle of inclination of 5° to 60° towards the occupant. This angle can be fixed or, at least within a portion of the specified range, variably adjusted.

[0014] Furthermore, the overall display can have an arc angle ranging from 50° to 180°. Depending on the size of the main display and any secondary displays, the arc angle can vary. This arc angle ensures that the overall display completely covers at least the occupant's field of vision. This means that the arc angle may even be larger than the field of vision. For example, in the case of the front passenger, a film can be shown within their field of vision, while incoming social media posts or the remaining travel time can be displayed outside their field of vision, but still within their view. These can be viewed with a slight head turn and / or eye movement. The field of vision is the area perceived without eye movement, and the viewing area is the area perceived with eye movement. The arc angle of the overall display can be divided between one of the main displays and at least one secondary display.For example, the at least two displays can each have an arc angle of at least 35°, and the at least one secondary display can have an arc angle of at least 15°. The displays and / or the secondary display can have a height of 100 mm to 600 mm.

[0015] In a further embodiment of the invention, the vehicle display system can include a control unit. This unit can, for example, adjust the screen resolution when a secondary display is activated. It can also be responsible for selecting the information displayed on the individual displays. The control unit ensures, for example, that all legally required information is visible on the driver-facing display at all times while the vehicle is in motion.

[0016] In a further embodiment of the invention, multiple displays can be configured in the driver's, front passenger's, and / or rear passenger areas. This can be offered as optional equipment. The standard equipment of a motor vehicle might, for example, only include the displays according to the invention for the driver and front passenger, while secondary displays and / or displays for the rear passengers are optional extras. This allows, for example, the basic mechanism to remain unchanged for all vehicles, and in the standard configuration, the secondary displays are concealed by "normal" door panels. Furthermore, simple operation via voice control or button presses can be implemented.

[0017] Exemplary embodiments and variants of the invention are explained in more detail below with reference to the drawing. The drawing shows Fig. 1a,b a schematic representation of the invention, and Fig. 2 a detail of the invention.

[0018] Fig. Figure 1a shows a partial schematic representation of a vehicle display system 1 of a motor vehicle 20. The one in the Fig. The vehicle display system 1 shown in Figure 1a comprises two total displays 1.1, 1.2, each of which has one display configured as a main display 2, 4 and two secondary displays 3.1, 3.2, 5.1, 5.2. In the example shown, the main displays 2, 4 have a height h of, for example, less than or equal to 500 mm. The angle of attack ω to the dashboard 6, which is assumed to be parallel to the road, is greater than or equal to 45° in the example shown.

[0019] Alternatively, displays 2, 4, 3.1, 3.2, 5.1, 5.2 can have a variable height h and a variable angle of attack ω. For example, the secondary displays 3.1, 3.2, 5.1, 5.2 can have a slightly reduced height h relative to the main display 2, 4, and the angle of attack ω can also vary in the direction away from the main display 2, 4 towards the edge of the secondary displays 3.1, 3.2, 5.1, 5.2.

[0020] The arc angle of the overall display in the example shown is almost 180°, thus roughly corresponding to the human field of vision, which is typically between 180° and 200°. The main displays 2 and 4 have an arc angle α of 90°, and the secondary displays 3.1, 3.2, 5.1, and 5.2 each have an arc angle β and δ of 45°. The orientation of the overall displays 1.1 and 1.2 is directed towards the occupants, as shown in the Fig. 1a using the example of the passenger represented as a circle 21.

[0021] The overall display 1.1 on the driver's side is partially obscured by the steering wheel 7, but this can be compensated for by a slight head movement of the driver.

[0022] The secondary displays 3.1, 3.2, 5.1, 5.2 are arranged on one side on the seat-facing side of the center console 9 and on the other side are integrated into the door trim 8.2.1 of the doors 8.1, 8.2.

[0023] Fig. Figure 1b shows the identical section of the motor vehicle 20 with the vehicle display system 1, wherein in the Fig. In illustration 1b, door 8 on the passenger side is shown open. This is indicated by a curved double arrow in the Fig. 1b is indicated. In this state, a signal is transmitted via a sensor (not shown) in door 8 to a control unit (also not shown) of the vehicle display system 1, indicating that door 8 is open and the secondary display 5.2 is not connected to display 4. The control unit can then adjust the screen resolution on display 4 and the second secondary display 5.1 so that all content previously displayed on the main display 1.2 continues to be shown.

[0024] Fig. Figure 2 shows a schematic representation of the rear compartment 16 of the motor vehicle 20 with a view to the front seats 10.1, 10.2 with the total displays 1.3, 1.4 arranged on them. These are as in the Fig. Section 1a explains the structure, which is why the structure is not described again here. The BZ symbols are derived from the BZ list. Each fund location 15.1, 15.2 has in the Fig.In the example shown, there is a combined display 1.3, 1.4, each of which is directed at the occupants of the individual seats 15.1, 15.2. Due to the identical design of the displays for both rear seats 15.1, 15.2, the same reference symbols are used for display 11 and the secondary displays 12.1, 12.2 for both combined displays 1.3, 1.4.

[0025] Alternatively, with suitable design of the secondary displays 12.1, the overall displays 1.3, 1.4 can also be combined to form a single screen (not shown) for both rear seats 15.1, 15.2.
