[0003] LIGHTING SYSTEM FOR A VEHICLE

[0004] The present invention relates to a lighting system for a vehicle, a vehicle and a method for operating a lighting system.

[0005] Vehicles incorporate a variety of lighting systems, each with different functions. Headlights illuminate the surroundings, particularly the roadway. Taillights signal the vehicle's arrival or braking. Both headlights and taillights also serve as turn signals and, in modern vehicles, provide daytime running lights that are activated regardless of the time of day or ambient light. Daytime running lights allow vehicles to have a distinctive appearance.

[0006] In addition to the lighting systems described above, whose integration into the vehicle and operation are strongly influenced by functionality (daytime running lights, illumination, direction indicator, braking process, taillight, etc.), there are lighting systems designed to signal information.

[0007] From DE 10 2011 111 422 A1, a multifunctional strip for a motor vehicle is known, which is designed as a strip-shaped trim element for the body of the motor vehicle and with which various pieces of information can be displayed independently of one another. The multifunctional strip can be attached to the outside of the body of the motor vehicle. This allows the driver, for example, to view relevant information from the motor vehicle before entering the vehicle.

[0008] The multifunction strip can retrieve information about the vehicle's operating components. It can also provide information to other road users. An optical display element of the multifunction strip can be, for example, a screen or display.

[0009] US Patent 2021 / 0 199 871 A1 discloses a lighting system comprising one or more light sources and one or more light guides. The lighting system can be integrated into a window, a skylight, an exterior light (headlight, taillight, or high-mounted brake light), or other external or internal components of a motor vehicle's system. Each light guide is embedded in an adhesive layer within a vehicle structure. The light guide is adapted to the adhesive layer such that 23-3765

[0010] Two unilluminated parts of the light guide are indistinguishable from the vehicle structure. The light guide can be formed from optical fibers. The optical fibers can include a light-scattering optical fiber that scatters the light out of the vehicle structure. The light-scattering optical fiber can be fused with a non-scattering optical fiber that guides the light from a light source to the light-scattering optical fiber.

[0011] US Patent 9,196,164 B1 discloses a system for notifying a pedestrian of the intentions of a self-driving vehicle. The vehicle includes sensors that detect an object, such as a pedestrian, attempting or about to cross in front of the vehicle. A processing unit within the vehicle then determines the appropriate response to the pedestrian. For example, it determines whether the vehicle should stop or slow down, swerve, or stop if it is safe to do so. The vehicle can inform the pedestrian of what it will do or is currently doing. For this purpose, the vehicle includes a physical signaling device, an electronic sign or lights, a speaker for audible notifications, etc.

[0012] User interfaces for a vehicle, designed to present visible information and capture user input, are also known, for example, from DE 102022 107 164 A1 or EP 3 916442 A1. Both documents describe the further development of screens with two-dimensional surfaces to replicate the perceived value and three-dimensional details of an analog instrument. Specifically, the use of an optical aperture with a two-dimensional display is proposed. The optical aperture comprises a contact surface on its underside for contacting the two-dimensional display, a three-dimensional display surface on its top side, and an optical light guide material positioned between the contact surface and the three-dimensional display surface. By using the optical aperture, a display system with a 3D surface can be provided, for example, by...B. conventional 2D display technologies are used.

[0013] It is an object of the invention to provide a lighting system for a vehicle that is structurally and / or functionally improved to make the interaction between the vehicle and a person more intuitive and safer. It is a further object of the invention to provide a vehicle that includes an improved lighting system to make the interaction between the vehicle and a person more intuitive and safer. Another object of 23-3765

[0014] 3

[0015] The invention consists of providing a method for operating a lighting system for a vehicle, which makes the interaction of the vehicle with a person more intuitive and safer.

[0016] These tasks are solved by the features of the independent claims. Advantageous configurations result from the dependent claims.

[0017] According to a first aspect of the invention, a lighting system for a vehicle is proposed. A vehicle is understood to be, in particular, a motor vehicle, a commercial vehicle, a motorcycle, etc. The lighting system is, in particular, an exterior light of the vehicle, such as a front light and / or a rear light and / or a decorative light. However, the lighting system can also be arranged inside the vehicle.

[0018] The lighting system includes a control unit, a display for showing information on a display section, and at least one optical aperture.

[0019] The control unit is a computing or data processing unit configured to display information on the display section of the screen in a predefined manner. The display section includes, or comprises, a light-emitting unit with a plurality of light sources, in particular an active-matrix display comprising a plurality of micro-LEDs, micro-OLEDs, OLEDs, or LCDs for emitting light. The display section specifically includes a pixel array. Alternatively, the display section can comprise an array of surface-mount LEDs (SMT LEDs). The display technology can have any resolution, e.g., 32 ppi to 300 ppi (pixels per inch).

[0020] Each optical aperture comprises a contact surface as a light coupling surface, a three-dimensional display surface with multiple display sections as light coupling surfaces for displaying information, and a fused optical waveguide material provided between the contact surface and the three-dimensional display surface. The contact surface faces the display or display section and is configured to transmit information from the light-emitting unit, e.g., pixel array, to the three-dimensional display surface. The term "fused optical waveguide material" refers to a melt in which multiple glass or polymer fibers are drawn, combined, and repeatedly drawn. The result is a solid, homogeneous glass or polymer into which 23-3765

[0021] Four optical fibers with controlled resolution are incorporated. The fiber diameter and density can be controlled or determined depending on the application, for example, to be compatible with the resolution of the display in the display area. The ends of the optical fibers are positioned in the contact surface and the three-dimensional display surface for coupling light in and out.

[0022] The control unit is designed to selectively display information on one or more of the display sections of at least one optical aperture, depending on an input signal received by the control unit.

[0023] The lighting system according to the invention is thus designed to selectively control one or more of the display sections of the display surface of the optical aperture or a plurality of optical apertures depending on an input signal. This enables interaction with an object, in particular a person located outside the vehicle, such as a pedestrian or cyclist, or another road user who is in the vicinity of the vehicle and / or moving along or around the vehicle. If the lighting system is located inside the vehicle, interaction with an occupant of the vehicle is possible.

[0024] In particular, a lighting system is created which makes it possible to control the lighting situationally depending on the presence of an object located near the vehicle, so that, regardless of the location and / or movement of the object relative to the vehicle, the displayed information is visible to the object.

[0025] According to a suitable embodiment, the display of information for each of the one or more display sections of the at least one optical aperture includes an individual setting of brightness (luminance and / or intensity) and / or color and / or content. In other words, this means that, depending on the input information, a single display section or a subset of the display sections of an optical aperture can have different settings with regard to brightness and / or color and / or content than other display sections of the same or other optical apertures.

[0026] This makes it possible, for example, to vary the brightness, color, and / or content settings depending on the object's location relative to the vehicle's lighting system. For example, on one or 23-3765

[0027] 5. In several display sections in the direction in which the object can perceive the information, brightness and / or color and / or content are displayed very clearly, while in display sections that deviate from the direction in which the object can perceive the information, the corresponding information is only dimmed or not displayed.

[0028] According to a further advantageous embodiment, the information displayed on several of the display sections of the at least one optical aperture is independent of one another. In other words, this means that the settings regarding brightness and / or color and / or content are, or can be, different on several of the display sections. The settings can also be varied, for example, depending on the distance of the object relative to the vehicle. For instance, by detecting the distance of a person (or object), the lighting pattern can be varied with regard to effective and / or perceived resolution. This makes it possible to increase or decrease the light output and / or optimize the lighting effect and / or the communication of content / information.

[0029] The term "content" refers to the ability to vary the lighting characteristics of each pixel or light source in each individual display area. This allows for the creation of visual effects or the reproduction of text or images.

[0030] Another advantageous design provides that the information displayed on several of the display sections of at least one optical aperture exhibits a dependency on each other, particularly in terms of timing. This makes it possible to display the information on several of the display sections according to the direction of movement of the object relative to the vehicle.

[0031] According to a further advantageous embodiment, the input signal is a sensor signal from a sensor of the vehicle or a signal fused from several sensor signals of respective sensors of the vehicle. In particular, the input signal can represent distance information, comprising a distance and / or a direction, to an object in the vicinity of the vehicle. The sensor can be, for example, an ADAS sensor (Advanced Driver Assistance System sensor), a lidar, a radar, a camera, an antenna (e.g., a UWB antenna), one or more ultrasonic sensors, or a combination of the aforementioned sensors. Using the aforementioned sensors, for example, 23-3765

[0032] 6. It is possible to detect objects in the vicinity of the vehicle and determine further information, e.g., distance and / or direction and / or speed of movement relative to the vehicle. This information can be processed to generate the input signal, which is then used to display the information appropriately on one or more of the display sections.

[0033] Alternatively or additionally, the input signal can be a signal representing the current status of the vehicle.

[0034] According to a further advantageous embodiment, the display comprises a flexible, curved, or pre-formed display layer or several flat display layers arranged in series, wherein a first optical aperture and at least one second optical aperture are arranged with different orientations in space on the display layer(s). Such a lighting system is known, for example, from EP 4224225 A1 of the applicant. The control unit is configured to selectively display the information, depending on the input signal, on the display sections of the first optical aperture and the at least one second optical aperture that are oriented in the same spatial direction. According to this embodiment, it is possible to output the same information on those display sections of a portion of the optical apertures that are oriented, for example, in the direction of the object, e.g., the pedestrian.In conjunction with a control system that includes a temporal dependency, those display sections can then be supplied with information that follow a direction of movement of the object.

[0035] According to a further advantageous embodiment, the control unit is designed to determine the spatial direction depending on an object outside the vehicle detected by one or more of the sensors and its relative position to the vehicle. The term "relative position" refers in particular to a (vector) direction relative to the vehicle as well as a distance from the vehicle. The (vector) direction can, for example, be represented by a vector in a vehicle coordinate system that is oriented, for instance, to the vehicle's longitudinal axis, transverse axis, and vertical axis.

[0036] In particular, the control unit can be configured to determine the spatial direction depending on a, especially predicted, direction of movement of the object relative to the vehicle. This makes it possible to direct the information specifically to that 23-3765

[0037] 7

[0038] to display sections that can be best perceived by the object located outside the vehicle.

[0039] According to a second aspect of the invention, a vehicle with a lighting system according to one or more embodiments of the invention is described. The vehicle has the same advantages as those explained above in connection with the lighting system according to the invention.

[0040] According to a third aspect of the invention, a method for operating a lighting system according to one or more embodiments of the invention is described. The method comprises the following steps: receiving a sensor signal; processing the sensor signal into a control signal for the lighting system; and generating information to be displayed selectively on one or more of the display sections of the at least one optical aperture, based on the control signal. The method according to the invention has the same advantages as those explained above in connection with the lighting system according to the invention.

[0041] The invention is described in more detail below with reference to an exemplary embodiment shown in the drawing. The drawing shows:

[0042] Fig. 1 shows a schematic representation of a vehicle according to the invention with several lighting systems according to the invention in a top view;

[0043] Fig. 2 shows a schematic representation of a lighting system according to the invention of the vehicle according to the invention from Fig. 1, which comprises a plurality of optical apertures on a curved display, wherein the lighting system illustrates by way of example a left rear light;

[0045] Fig. 4 shows the optical aperture from Fig. 3 in a side view; and

[0046] Fig. 5 shows a flowchart to explain the inventive method for operating the inventive lighting system. 23-3765

[0047] 8

[0048] Fig. 1 shows a schematic representation of a vehicle 1 according to the invention. The vehicle 1 is shown in a top view and moves in the plane of the sheet from top to bottom in the direction of arrow FR. The four wheels 2 on the left and right sides of the vehicle 1 are shown schematically. Also visible in the top view are a left front light 3, a right front light 4, a left rear light 5, and a right rear light 6. The left front light 3, the right front light 4, the left rear light 5, and the right rear light 6 constitute a lighting system 10 according to the present invention.

[0049] Vehicle 1 is, for example, a motor vehicle or a commercial vehicle. In particular, vehicle 1 may be equipped for at least partially autonomous driving, although the necessary technical components are not shown in detail.

[0050] In particular, the vehicle 1 can include several sensors. By way of example only, sensor 7 represents a camera, sensor 8 a radar (e.g., lidar), and sensor 9 an ADAS, i.e., a sensor unit designed to enable at least partially autonomous vehicle operation.

[0051] Sensors 7, 8, and 9 are coupled to a control unit 11. The control unit 11 receives corresponding sensor signals from sensors 7, 8, and 9 in order to process them in a predetermined manner. The control unit 11 is configured to control one or more of the lighting systems 10 in a manner described below. For this purpose, the control unit 11 is coupled to the left front light 3, the right front light 4, the left rear light 5, and the right rear light 6.

[0052] The control of one or more lighting systems 10 is achieved by processing the sensor signals received from sensors 7, 8, 9. These sensor signals therefore constitute input signals for the control unit 11. The control of each lighting system 10 can be based on the signal from a single sensor 7, 8, or 9, or on a fusion of the signals from multiple sensors 7, 8, and / or 9.

[0053] The processing of the sensor signals serves to determine objects 30 located in the vicinity of the vehicle 1 and their relative position to the vehicle. In Fig. 1, an example of an object 30 is a pedestrian outside the vehicle 1, who is moving from the front right side of the vehicle 1 along the right side in the direction 23-3765.

[0054] 9 of the rear of vehicle 1 moves. The processing of the sensor signals from sensors 7, 8, 9 by the control unit 11 can alternatively or additionally serve to enable at least partially autonomous vehicle control.

[0055] The relative position includes, for example, a (vector) direction relative to the vehicle, the vector preferably being defined in a vehicle-specific coordinate system. A Cartesian coordinate system, for instance, can be used, with its axes defined by a longitudinal axis, a transverse axis, and a vertical axis. In Fig. 1, such a vector is represented by the arrow marked with the reference symbol V.

[0056] The front lights 3, 4 and the rear lights 5, 6 (hereinafter referred to generally as: lighting system 10) are arranged in the body of the vehicle 1 in such a way that light can be emitted in several directions, e.g. forwards and to the right or forwards and to the left or to the rear and to the right or to the rear and to the left.

[0057] The respective lighting system 10 comprises, as can be seen more clearly in Figures 2 to 4, a display 12 for showing (light) information, wherein a plurality of optical apertures 20 are arranged on the display 12. The optical apertures

[0058] The 20 optical apertures are arranged in a regular grid, i.e., matrix-like, on a flexible display layer 14 of the display 12. The shape of the flexible display layer 14 follows the shape of the vehicle body 1. Each optical aperture 20 is arranged on a display section 13 of the display 12. The display 12, or each display section 13, comprises a light-emitting unit in the form of a pixel arrangement, which is not shown in detail in the figures. The display 12 is thus formed by the flexible substrate in the form of the flexible display layer 14 (see Fig. 4).

[0059] Each optical aperture 20 comprises a contact surface 21 as well as a three-dimensional display surface 22 with multiple display sections 22A-22E for displaying information and an optical light guide material 23 that is located between the contact surface

[0060] 21 and the three-dimensional display surface 22. The pixel arrangement of the display 12 or of a respective display section 13 is arranged in the area of ​​the contact surface 21, wherein each pixel of the display 12 in the display section 13 is assigned to a respective light guide of the light guide material 23. The ends of the light guides (not shown) facing away from the contact surface 21 terminate at respective display sections 22A-22E. As can be seen from the top view of Fig. 3 23-3765

[0061] In the present embodiment, the three-dimensional display surface 22 has five display sections 22A-22E, such that the sections have the shape of facets.

[0062] The detailed design of the optical apertures can be found, for example, in EP 3 916 442 A1 or EP 4224225 A1 of the applicant. The content of these publications is incorporated by reference and briefly described below.

[0063] The optical aperture 20 can be positioned, for example, on a 2D display, specifically on the flexible display layer 14. The contact surface 21 can touch the display surface of the flexible display layer 14, allowing the light emitted by the flexible display layer 14 in the area of ​​its display section 13 to be received by the contact surface 21. The optical light guide material 23 is configured to transmit the light from the contact surface 21 to the three-dimensional display surface 22. Consequently, when using the optical aperture 20, the light, i.e., the display content in the area of ​​the display section 13, can be displayed and appear on the three-dimensional display surface 22 of the optical aperture 20. Since the three-dimensional display surface 22 has a more complex (three-dimensional) surface geometry, the optical aperture 20 enables the provision of a 3D display using 2D display technology.

[0064] The optical waveguide material intended to transmit light from the contact surface 21 to the three-dimensional display surface 22 can, for example, consist of polymer and / or glass. Any translucent material (e.g., a transparent material) can be used. Further improvements for controlled (e.g., directional) transmission can be achieved if the waveguide material is, for example, a fiber-based material. The optical waveguide material 23 can, for example, be configured to transmit light from a specific first section of the contact surface 21 to a specific first section of the three-dimensional display surface 22.For example, the light received at the first section of the contact surface 21 can only be transferred to the first section of the three-dimensional display surface 22, but not to other, second sections of the three-dimensional display surface 22.

[0065] Upon contact with the flexible display layer 14, light received in the area of ​​the display section 13 of the contact surface 21 is transmitted via the optical fibers and displayed on a corresponding display section 22A-22E of the three-dimensional display surface 22A. The two-dimensional display in the area of ​​23-3765

[0066] 11

[0067] Display section 13 of the flexible display layer 14 can have any shape, e.g. rectilinear (any aspect ratio), circular, octagonal, complex shape, etc.

[0068] For example, the surface area of ​​the contact surface 21 can differ from the surface area of ​​the three-dimensional display surface 22. This allows, for example, the size of the display to be changed for the user. For instance, the three-dimensional display surface 22 can be larger than the contact surface 21, thus achieving a larger display area.

[0069] The two-dimensional display in the area of ​​display section 13 of the flexible display layer 14 can, for example, be a small, high-resolution display, and the optical aperture 20 can be used to enlarge the surface area while accepting a lower resolution on the three-dimensional display surface 22. The two-dimensional display of the flexible display layer 14 can be a projection module, a micro-LED display, a micro-display, etc. For example, the dimensions of sections of display section 13 can be designed differently to achieve a magnification effect. In general, the optical aperture 20 can allow the display size of display section 13 to be increased or decreased.

[0070] ZB, the area of ​​the three-dimensional display surface (i.e., the display section 13) can be at least 1.3 times (or at least 1.5 times, at least 2 times, or at least 3 times) and / or at most 5 times (or at most 3 times or at most 2 times) the area of ​​the display section 13. This can make it possible to provide the optical aperture 20 with a modified display size, adapted, for example, to a specific two-dimensional display and / or a specific application, such as the front lights 3, 4 or rear lights 5, 6.

[0071] For example, the three-dimensional display surface 22 can be at least partially curved. For example, the three-dimensional display surface can be curved with respect to at least two axes. Likewise, the three-dimensional display surface 22 can have a dome shape, although the aforementioned examples are not shown in the figures.

[0072] As can be seen in the examples according to Figures 2 to 4, the three-dimensional display surface 22 can comprise a plurality of planar surface sections 22A-22E, which 23-3765

[0073] 12 are arranged at a predetermined angle to each other, e.g., at least 5° (or at least 10°, at least 20°, at least 30° or at least 45°) and / or at most 90° (or at most 60°). This ensures an improved appearance of the three-dimensional display surface 22 for the user.

[0074] For example, two separate display sections 22A-22E, e.g. for different display content, can be separated into two planes arranged at a specific angle to each other. The three-dimensional display surface 22 can, e.g., have a faceted shape, such as that of a cut diamond, as shown here.

[0075] It is also possible that the display sections 22A-22E form a specific shape to transmit information. For example, the display sections 22A-22E can have an arrow or triangle shape which, when illuminated, provides a directional indication (e.g., illuminated arrows). This allows different information, such as the status, direction, or movement of the vehicle, to be transmitted to object 30 depending on the actions of the sensor-detected object 30 and vehicle 1.

[0076] A two-dimensional display formed by the flexible display layer 14, which can be used with the optical aperture 20 or a plurality of optical apertures 20, can be a display or a display device with a substantially flat or curved display surface. For example, the entire display of the two-dimensional display device can extend in a plane. In the embodiment shown here, the flexible display layer 14 is curved and adapted to the shape of the body of the vehicle 1. Any display technology can be used for the display, e.g., liquid crystal display (LCD), light-emitting diodes (LEDs), backlit LCD, thin-film transistor LCD (TFT), LED display, OLED display, AMOLED display, plasma display (PDP), quantum display (QLED), or a projection-based approach.

[0077] The contact surface 21 can be a planar surface. The planar surface can be flat, e.g., in an XY coordinate system. As shown, the planar surface can be curved, e.g., with respect to a single axis, to enable its use in combination with the curved flexible display layer 14.

[0078] According to the invention, the control unit is designed to selectively display the information on one or more respective display sections 22A-22E of the plurality of optical apertures 20 of the 23-3765, depending on the input signal described above, which is derived from the signals of the sensor(s) 7, 8, 9.

[0079] 13

[0080] The lighting system 10, as shown in Fig. 2, is displayed. This makes it possible, depending on the relative position of the object 30 to the vehicle detected by the sensors 7, 8, 9, only to display information on those display sections 22A-22E of the optical apertures 20 which are oriented in the spatial direction of the object 30, i.e., the pedestrian. The display of the respective information on the display sections 22A-22E can, in particular, include individual adjustment of brightness (dominance and / or intensity) and / or color and / or content. In particular, in the case of a pedestrian moving in a direction of movement 31 around or along the vehicle, as shown in Fig.As can be seen from section 1, it is provided that, for example, display sections 22A are initially illuminated with the relevant information, while, as the pedestrian moves towards the text "vehicle", display sections 22E and finally display sections 22C are illuminated. This ensures that the pedestrian always receives visual information from vehicle 1, regardless of their location relative to the vehicle.

[0081] It is also possible that the information displayed on several of the display sections 22A-22E by the optical apertures 20 is temporally dependent on one another. In this way, it is possible to transmit animated information towards the pedestrian 30. This allows various visual effects to be displayed, which are generated independently of each other or coordinated between the display elements 22A-22E.

[0082] In principle, it is possible to display the information on the respective display sections 22A-22E independently of each other or in coordination with each other.

[0083] In particular, the sensor data acquired by sensors 7, 8, 9 can be used to display a time-based animation using the display sections 22A-22E on the lighting system 10.

[0084] Visibility and visual display effects towards pedestrians or other road users, e.g. drivers, can be varied depending on the angle or direction of viewing.

[0085] Fig. 5 shows a schematic flow chart of the method according to the invention. In step S1, the sensors 7, 8, 9 available in a vehicle are used to measure the available 23-3765

[0086] 14

[0087] Sensor data is acquired and fed to the control unit 11 for processing. In step S2, optionally publicly available data from the vehicle 1, which is retrieved, for example, from a decentralized database or provided to the vehicle via a vehicle user interface, is fed to the control unit 11 for processing. In step S3, the control unit 11 determines control signals (S31) from the received input data to control the individual display sections 22A-22E of the optical apertures 20 of one or more lighting systems 10 of the vehicle 1. For each display section 22A-22E of each optical aperture 20 of each lighting system 10, individual settings for brightness and / or color and / or content are determined independently.The relevant information is converted into suitable control signals for the respective display section 13 assigned to the optical aperture 20 and is thereby supplied either to individual display sections (S32) and / or the entire optical aperture (S33) and / or an array of optical apertures (S34) and / or the lighting system 10 as a whole (S35).

[0088] In a further development of the procedure, it may be provided that the vehicle mode or state is taken into account by control unit 11. Depending on whether, for example, the vehicle is parked, stationary, moving / driving, stopped (e.g., with the brakes applied), stopped at a stop sign or traffic light, charging an EV, etc., the communication with object 30 can differ depending on the vehicle mode / state. If the vehicle is parked, for example (either occupied or unoccupied), the display for object 30 would differ depending on its position and / or direction of travel compared to when the vehicle is in motion (accelerating, braking, or at a constant speed), e.g., for safety reasons.
