Description

[0001] Motor vehicle with lighting device

[0002] The present invention relates to a motor vehicle with a lighting device which is activated and illuminates depending on a state of the motor vehicle.

[0003] Such a motor vehicle is known from DE 102015 012 724 A1. The motor vehicle has a lighting system with at least one design element located outside the headlights, turn signals, and taillights of the motor vehicle. The at least one design element is illuminated depending on the vehicle's locking system.

[0004] DE 102018 101 956 A1 discloses vehicle lighting and in particular the lighting provided by windows, sunroofs, sliding roofs or other transparent vehicle elements.

[0005] DE 100 58 903 A1 discloses a lighting arrangement for a motor vehicle with lighting units for illuminating the surroundings of the motor vehicle in order to improve the visibility of a vehicle occupant located in a passenger compartment of the motor vehicle while driving.

[0006] DE 102 41 378 A1 discloses a lighting device which is intended for signalling various information on a vehicle and which fits into the structural conditions in the vehicle.

[0007] DE 10201 7202 924 A1 discloses a motor vehicle with a lighting arrangement that is individually adjustable.

[0008] The present invention addresses the problem of providing an improved or at least different embodiment for a motor vehicle of the aforementioned type. This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0009] The present invention is based on the fundamental idea of ​​installing a lighting device in a motor vehicle which, when activated, emits light that is visible from the outside surrounding the motor vehicle. The lighting device is activated depending on predetermined events, so that light associated with the event is generated and emitted, which light is visible from the outside and surrounding the vehicle to persons outside the motor vehicle. This increases safety, in particular because said person outside the vehicle is informed accordingly about the event, and the information is more easily recognizable due to the circulating emission of the associated light, in particular regardless of the person's current position.

[0010] Said events include objects in the vicinity of the motor vehicle and / or braking of the motor vehicle and / or activation of a hazard warning device of the motor vehicle and / or an operating state of a driver assistance system of the motor vehicle.

[0011] According to the inventive concept, the motor vehicle has a lighting device. The lighting device is housed in an interior panel of the motor vehicle and extends circumferentially around the motor vehicle, so that, when active, the lighting device generates light that is visible from outside the motor vehicle. Furthermore, the motor vehicle has a control device for activating the lighting device.

[0012] In a first solution according to the invention, the motor vehicle has a detection device for detecting objects in the surroundings of the motor vehicle. The detection device can, for example, have at least one camera, a radar sensor, and the like. The control device is designed such that it activates the lighting device depending on an object detected by the detection device, so that the lighting device generates light associated with the object, which light is visible from outside the motor vehicle all around the motor vehicle. Thus, both persons inside and outside the vehicle can be informed of the detection of the object. The lighting device expediently has at least one light source for generating the light.

[0013] Preferably, the lighting device is capable of generating light of different colors. For this purpose, the lighting device advantageously comprises at least one LED.

[0014] Preferably, the lighting device is arranged in the interior paneling of at least one window of the motor vehicle, preferably at a lower edge of the window. The window can be a window and / or a windshield and / or a rear window.

[0015] Preferred embodiments are those in which the lighting device extends circumferentially along the entire vehicle, so that, when active, the light from outside the vehicle can be seen circumferentially. The lighting device thus achieves what is known as 360° illumination projected outward. This 360° illumination can, of course, be interrupted within gaps, for example, doors and / or a trunk and / or a hood.

[0016] According to the invention, at least two objects, at least one motor vehicle owner and one third party, are each assigned a color of light.

[0017] This makes it possible to signal to a cyclist or pedestrian that they have been detected.

[0018] The vehicle owner, i.e., a person authorized to access the vehicle, can also be signaled that the person has been detected, or that the person has been detected approaching and / or departing from the vehicle. This can be part of a so-called "welcome" and "goodbye" signaling.

[0019] A third party, i.e., someone without access authorization to the vehicle, can thus be issued a warning, similar to a so-called "watchdog function." The corresponding light is selected accordingly. It is preferred if a corresponding light color is assigned to the respective object.

[0020] The motor vehicle may have a driver assistance system. Preferably, the control device is alternatively or additionally configured to activate the lighting device depending on an operating state of the driver assistance system, so that the lighting device generates light associated with the operating state, which is visible from outside the motor vehicle all around the motor vehicle. This makes it easy to signal to the outside that a driver assistance system of the motor vehicle is activated and / or deactivated.

[0021] The detection device can be part of the driver assistance system.

[0022] Alternatively or additionally, the control device can be designed such that it activates the lighting device depending on an activated service brake and / or a hazard warning function, so that the lighting device generates light associated with the service brake and / or the hazard warning function, preferably light with an associated color.

[0023] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0024] It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

[0025] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0033] A motor vehicle 1, as shown by way of example in Figures 1 to 7, has a lighting device 2, as shown by way of example in Figure 2. The lighting device 2 is, as can be seen from Figure 2, accommodated in an interior panel 3 of the motor vehicle 1 and generates light L in the active state. The lighting device 2 extends, as can be seen from the light L indicated in Figures 1 and 3 to 7, all the way around the motor vehicle 1, so that the lighting device 2 in the active state generates light L that can be seen from outside the motor vehicle 1 all the way around the motor vehicle 1. In the exemplary embodiments shown, the lighting device 2 extends all the way around the entire motor vehicle 1, so that in the active state the light L can be seen from outside the motor vehicle 1 all the way around the motor vehicle 1.In the active state, the lighting device 2 thus generates so-called 360° illumination to the outside. As can be seen in particular from Figure 2, in the exemplary embodiments shown, the lighting device 2 is arranged circumferentially on the lower edge of surfaces 4, namely window panes 5, a windshield 6 and a rear window 7 of the motor vehicle 1. The generated light L is thus easily recognizable for outsiders. In the exemplary embodiments shown, the lighting device 2 comprises, as indicated in Figure 2, at least one LED 8, so that the lighting device 2 can generate light L of different colors in the active state.

[0034] In the exemplary embodiments shown, the motor vehicle 1 has a detection device 9, only symbolically indicated in Figure 2, for detecting objects 11 in the surroundings of the motor vehicle 1. The detection device 9 can, for example, have at least one camera (not shown) and / or at least one radar sensor (not shown). The motor vehicle 1 has a control device 10, only symbolically indicated in Figure 2. The control device 10 is connected to the lighting device 2 (not shown) in such a way that the control device 10 can activate the lighting device 2.The control device 10 is configured such that it activates the lighting device 2 depending on an object 11 detected by the detection device 9, such that the lighting device 2 generates light L associated with the object 11, which light can be recognized from outside the motor vehicle 1 according to the path of the lighting device 2 surrounding the motor vehicle 1. The lighting device 2 generates respective light L for at least two different objects 11, in the exemplary embodiments shown, each light L with an associated color.

[0035] The object 11 may, as shown in Figure 1, be a cyclist 12, who is signaled by the associated light L, for example blue light L, that he has been detected.

[0036] The object 11 may, as shown in Figure 3, be a pedestrian 13, who is signaled with the associated light L, for example with blue light L, that he has been detected.

[0037] As indicated in Figure 4, the object 11 may be a stranger 14, i.e., a person 14 without access authorization to the motor vehicle 1. The associated light L, for example, a red light L, can signal the stranger 14 that he or she has been recognized, thus issuing a visual warning in the manner of a "watchdog" function.

[0038] As indicated in Figure 5, upon detection of a person (not shown) authorized to access motor vehicle 1 as object 11, corresponding light L can be emitted by the lighting device 2. It is conceivable to generate different light L, in particular light L of different colors, as the person approaches motor vehicle 1 and as the person moves away from motor vehicle 1. For example, white light L can be generated and emitted as the person approaches, and yellow and / or orange light L as the person moves away.

[0039] The motor vehicle 1 can have a driver assistance system 15, which is only symbolically indicated in Figure 2. The control device 10 can be configured such that, as indicated in Figure 6, it activates the lighting device 2 depending on an operating state of the driver assistance system 15, so that the lighting device 2 generates light L associated with the operating state, which light is recognizable from outside the motor vehicle 1 as encircling the motor vehicle 1. For example, when the driver assistance system 15 is activated, blue light L can be generated and emitted.

[0040] As indicated in Figure 7, the control device 10 can alternatively or additionally be configured such that it activates the lighting device 2 depending on an activated service brake (not shown) and / or a hazard warning function, so that the lighting device 2 generates and outputs light L associated with the service brake and / or the hazard warning function. For example, the service brake light L can be assigned red, and the hazard warning function light L can be assigned yellow / orange.
