Background Art

[0002] DE 10 2004 045 690 A1 discloses a device for determining external sound sources in a motor vehicle environment, the device having a microphone array arranged on the motor vehicle and an evaluation device for evaluating microphone signals. The microphone array has a plurality of microphones for receiving ambient noise of the motor vehicle. Summary of the invention

[0003] The object of the present invention is to provide a logo lighting device for illuminating a logo of a motor vehicle, a system for arranging a logo lighting device on a component of a motor vehicle, and a method for operating a motor vehicle, which allow the installation space of the motor vehicle to be designed particularly advantageously.

[0004] This object is achieved according to the invention by a logo lighting device for illuminating a logo of a motor vehicle having the features of claim 1, by a system for arranging the logo lighting device on a component of a motor vehicle having the features of claim 6, and by a method for operating a motor vehicle having a logo lighting device having the features of claim 10. Advantageous embodiments of the invention are the subject of the dependent claims and the description.

[0005] A first aspect of the present invention relates to a logo lighting device for illuminating a logo of a motor vehicle. The motor vehicle is preferably designed as a motor vehicle, in particular a passenger car, a commercial vehicle or a truck.

[0006] The identification can be understood in particular as an official identification of a motor vehicle. The identification can be referred to in particular as a motor vehicle identification (KFZ identification) or a number plate. For example, the identification is arranged on the outside of the motor vehicle in the rear region of the motor vehicle, in particular in or on the rear of the vehicle, in the fully manufactured state of the motor vehicle.

[0007] The marking lighting device has at least one housing element, which at least partially, in particular completely, delimits the receiving space. In other words, the receiving space is at least partially, in particular completely, surrounded by the housing element or formed by the housing element. The receiving space is therefore at least partially, in particular completely, covered by the housing element. The receiving space is part of the marking lighting device. This means that the marking lighting device includes the receiving space.

[0008] The identification lighting device has at least one lighting element arranged in the accommodating space for illuminating the identification. Therefore, the lighting element is arranged in the housing element. This means that the lighting device can be integrated in the housing element, which can be referred to as a housing in particular. In other words, the identification can be illuminated by means of the lighting element. For example, the lighting element has at least one light source. Preferably, the lighting element, in particular the light source, is configured to emit or transmit light. The identification can be illuminated by light emitted by means of the lighting element, in particular the light source. Therefore, the lighting element, in particular the light source, can be understood as a lamp in particular. For example, the lighting element is configured as a light emitting diode (LED). Preferably, a plurality of lighting elements, for example two lighting elements, which are configured to illuminate the identification are arranged in the accommodating space. The lighting element is configured as a light emitting diode (LED), for example.

[0009] For example, the marking lighting device is held on the outside of the body frame of the motor vehicle, in particular via a housing element, in particular at least indirectly or directly on the body frame or on a structural element of the motor vehicle that is constructed separately from the body frame. This means that the marking lighting device is arranged or fastened on the outside of the body frame in the fully manufactured state of the motor vehicle. Here, the marking lighting device can be held or fastened on the body frame, in particular at least indirectly, via a structural element. The marking lighting device can therefore be arranged or has been arranged outside the body frame. The body frame can be understood in particular as a structure of the motor vehicle. Preferably, the body frame is constructed as a body that is in particular self-supporting.

[0010] In order to be able to design the structural space of the motor vehicle particularly advantageously, in particular to be able to keep the structural space particularly small, it is provided according to the present invention that at least one, particularly acoustic, sensor element is arranged in the accommodation space, by means of which at least one acoustic signal from the surroundings of the motor vehicle can be detected or detected, particularly in the installation position of the identification lighting device in the motor vehicle. Therefore, the sensor element is arranged in the housing element. This means that the sensor element can be integrated in the housing element. In other words, the sensor element is at least partially, particularly completely surrounded by the housing element. In other words, the sensor element is at least partially, particularly completely covered by the housing element. Acoustic signals can be understood in particular as noise from the surroundings of the motor vehicle. This means that acoustic signals or noise emitted by a noise source located in the surroundings of the motor vehicle can be detected by means of a sensor element. Therefore, an acoustic signal in the form of sound or sound waves can be emitted by a noise source and received or detected by a sensor element. The noise source can be understood in particular as a sound source. The sensor element is configured as a microphone, for example.

[0011] For example, at least one variable characterizing the acoustic signal can be detected by means of the sensor element. For example, the detected variable is transmitted by the sensor element to an electronic computing device, wherein the acoustic signal can be ascertained or evaluated by means of the electronic computing device based on the detected or transmitted variable.

[0012] The noise source is preferably a person, especially in the surroundings of the motor vehicle. The acoustic signal can therefore be a noise emitted by a person, especially caused by a person. Preferably, the acoustic signal or noise is a person's, especially human speech. In particular, human speech can be understood to mean a sound generated by the vocal cords in the throat of a person and modulated in the vocal tract, in particular the oral cavity and / or pharynx and / or nasal cavity of the person. The acoustic signal or noise is therefore, for example, a voice command.

[0013] The present invention is based in particular on the following recognition and consideration: a vehicle, in particular a motor vehicle, can be operated from the outside using mechanical and / or electrical elements. For example, a handle, a button, a switch, a radio remote control or a targeted movement of an operator can be used here. For example, a wing element of a motor vehicle, in particular a rear hatch, can be operated by a tactile element, such as a button, a logo operating device or the like. Alternatively or additionally, a wing element, in particular a rear hatch, can be operated by an internal key, a remote control or a targeted movement of a person. The targeted movement of a person can be in particular a contactless operation, that is, a contactless movement involving a motor vehicle that is not touched by a person. Here, a targeted movement can be, for example, a movement of a person's foot, in particular called a kick. The operation or opening of a motor vehicle, in particular a wing element, such as a rear hatch, can be in particular called a smart opener (SMO). The rear hatch can be triggered in particular by a kicking movement of a foot or the rear bumper of a motor vehicle. The operation performed by a targeted movement in the form of a contactless operating part (smart opener) may be unintuitive and particularly error-prone for a person. This may have a negative impact on the comfort of the motor vehicle. By contrast, with the aid of the identification lighting device according to the invention with at least one sensor element, the motor vehicle can be operated from the outside, i.e. from the surroundings, by voice operation or by voice commands. This means that the motor vehicle can be voice-controlled by a person in the surroundings. Thus, for example, the wing elements and / or windows of the motor vehicle can be opened and / or closed by a person by means of voice operation or voice control. As a result, the motor vehicle can be controlled or operated from the outside particularly inexpensively and particularly particularly intuitively. In particular, the wing elements and / or windows can be opened or closed particularly inexpensively and particularly particularly intuitively. As a result, the comfort of the motor vehicle can be particularly increased.

[0014] Since the marking lighting device, in particular the sensor element, is arranged on the outside of the motor vehicle or the body frame, it is possible, for example, to detect acoustic signals particularly accurately and / or reliably. As a result, the motor vehicle, in particular the wing elements and / or the windows, can be operated particularly reliably by a person. This can particularly increase the comfort of the motor vehicle.

[0015] By arranging the sensor element in the marking lighting device or in the housing element or in the receiving space, the structural space of the motor vehicle can be designed particularly advantageously, in particular, kept particularly small. Here, in addition to arranging the sensor element, for example, an existing structural space in the form of a marking lighting device or in the form of a receiving space can be utilized, and the existing structural space can be used to arrange the lighting element. Therefore, the sensor element can be arranged in the motor vehicle in a particularly space-saving manner. In other words, the sensor element can be installed or arranged in an existing external component in the form of a marking lighting device or a housing element in the motor vehicle. In particular, a dual function can be achieved by means of the marking lighting device, namely illuminating the logo by means of the lighting element and detecting acoustic signals from the surrounding environment of the motor vehicle by means of the sensor element. This means that multiple functions or purposes of the motor vehicle can be achieved by means of the marking lighting device. Thus, for example, additional parts or components of the motor vehicle can be omitted. Therefore, for example, the weight of the motor vehicle can be kept particularly small.

[0016] In particular, by arranging the sensor element inside the receiving space or at least partially covered by the housing element, the sensor element can be arranged particularly reliably in the motor vehicle, in particular in the identification lighting device. The sensor element can thereby be protected particularly reliably from damage, for example. The service life of the sensor element can thereby be particularly increased. Furthermore, the sensor element can be arranged in the motor vehicle, in particular in the receiving space, covered or not visible from the surroundings. As a result, for example, the appearance or design of the motor vehicle can be designed particularly advantageously.

[0017] A wing element may be understood, for example, as a flap element, in particular a flap. For example, the flap element is a tailgate or a door, in particular a side door, of a motor vehicle.

[0018] In particular, if the wing element is designed as a tailgate, it can be provided that the person is located near the tailgate when the tailgate is opened or when the voice command is given. Since the identification lighting device is arranged in the rear region of the motor vehicle, in particular on the outer side of the motor vehicle, the acoustic signal can be detected particularly well, particularly precisely and / or particularly reliably. This can be achieved, for example, in that the person is located particularly close to the identification lighting device and is therefore located on the sensor element when the tailgate is opened or when the voice signal is given.

[0019] In another embodiment, it is provided that the lighting element and the sensor element are arranged directly on a carrier element which is constructed separately from the housing element and which is in particular a common carrier element. In other words, the lighting element and the sensor element are held or fastened directly on the carrier element. This means that the lighting element and the sensor element can be mounted together on a carrier element, in particular a circuit board. This makes it possible to design the structural space of the marking lighting device particularly advantageously, in particular to keep it particularly small. The carrier element is constructed, for example, as a circuit board. Preferably, the carrier element is arranged in particular completely in the receiving space.

[0020] Preferably, provision is made for the housing element to be liquid-tight, in particular water-tight. For example, at least one sealing element is arranged, in particular directly, on the housing element, by means of which the housing element can be sealed or sealed relative to the surroundings of the marking lighting device. Liquid-tightness, in particular watertightness, can thus be achieved by means of the sealing element. The marking lighting device, in particular the housing element, can thus be kept particularly tight. The sensor element can thus be particularly well protected from damage caused by moisture, for example. The sensor can thus be arranged or installed in a wet area of ​​a motor vehicle, in particular in the vehicle exterior.

[0021] Preferably, the sensor element has at least one opening, which is provided for the sound to enter the interior of the sensor element. In other words, the acoustic signal can be transmitted, in particular acoustically, into the interior of the sensor element through the opening for detecting the acoustic signal. This means that the opening is provided for the acoustic signal to enter acoustically into the sensor element, in particular into the interior.

[0022] It is preferably provided that the opening is covered by the diaphragm in a liquid-tight manner, for example watertightly, in particular directly. In other words, the opening is at least partially, in particular completely, surrounded by the diaphragm in its axial direction, in particular outwardly. In other words, the diaphragm is arranged in particular directly on the opening. This means that the opening is at least partially, in particular completely, closed by the diaphragm. As a result, the interior of the sensor element can be protected particularly reliably against the ingress of liquid or moisture.

[0023] The diaphragm is preferably configured to transmit sound or can transmit sound. Therefore, the diaphragm can be referred to as a sound diaphragm in particular. This means that the diaphragm can transmit sound waves, in particular acoustic signals, applied from a first side through the diaphragm to a second side of the diaphragm that is different from the first side and in particular opposite to the first side. The first side is preferably the outside of the diaphragm or the sensor element. The second side is preferably the inside of the diaphragm or the sensor element. This means that the second side is preferably facing the inner cavity and the first side is preferably facing away from the inner cavity.

[0024] Preferably, provision is made for the lighting element to be arranged in a first plane, in particular for the lighting element to be arranged in the first plane and for the opening to be arranged in a second plane different from the first plane, in particular spaced apart from the first plane. In other words, the opening is spaced apart from the first plane, in particular obliquely or perpendicularly to the extension direction of the first plane. As a result, the acoustic signal can be detected particularly well, in particular without errors or in a particularly interference-resistant manner, by means of the sensor element.

[0025] For example, it is provided that the carrier element is arranged in a first plane and the corresponding opening is arranged in a second plane. In other words, the opening is spaced apart from the carrier element, in particular obliquely or perpendicularly to the plane or the plane of extension of the carrier element. As a result, the acoustic signal can be detected particularly well, in particular particularly robustly or without faults, by means of the sensor element.

[0026] For example, at least one second sensor element, which is constructed separately from the sensor element and is particularly acoustic, is arranged in the accommodation space, by means of which acoustic signals from the surroundings of the motor vehicle can be detected or detected. As a result, for example, direction recognition and / or distance recognition of acoustic signals can be achieved particularly reliably and / or precisely. As a result, for example, background noise in the surroundings of the motor vehicle can be filtered out in a targeted manner. As a result, the detection of acoustic signals can be particularly improved, and in particular, acoustic signals can be detected particularly precisely and / or reliably. As a result, the motor vehicle, in particular the wing elements and / or the windows, can be operated particularly reliably by the personnel. As a result, the comfort of the motor vehicle can be particularly improved. Preferably, the second sensor element is spaced apart from the first sensor element, in particular, which is referred to as the first sensor element. For example, the second sensor element is configured as a microphone.

[0027] In another embodiment, the sensor element is arranged directly on the carrier element. In other words, the sensor element is held or fastened directly on the carrier element. This means that the sensor element can be mounted together on the carrier element, in particular on a circuit board. This makes it possible to design the structural space of the marking lighting device particularly advantageously, in particular to keep it particularly small.

[0028] For example, it is provided that the sensor elements are designed collectively as a sensor element array, in particular a microphone array. This allows, for example, particularly precise direction identification of acoustic signals. The detection of acoustic signals can thus be improved particularly precisely.

[0029] A second aspect of the present invention relates to a system for arranging a logo lighting device having a housing element for illuminating a logo of a motor vehicle, in particular according to the first aspect of the present invention, on a structural element of a motor vehicle. The structural element is, for example, configured as a body frame part of a body frame of a motor vehicle, or the structural element is configured separately from the body frame. For example, the structural element is configured as a wing element, in particular a rear hatch. The housing element at least partially, in particular directly, delimits a receiving space in which at least one lighting element for illuminating the logo is arranged. The advantages and advantageous designs of the first aspect of the present invention can be regarded as advantages and advantageous designs of the second aspect of the present invention, and vice versa.

[0030] The marking lighting device is preferably arranged on the outside of the motor vehicle, in particular the body frame. In other words, the marking lighting device is located on the outside of the motor vehicle or the body frame. This means that the marking lighting device is not arranged in the inner cavity of the motor vehicle, in particular the vehicle interior or the passenger compartment. The marking lighting device is therefore spaced apart from the inner cavity. The marking lighting device can be held on the outer side of the body frame, in particular at least indirectly or directly, on the structural element and / or on the body frame, in particular via a housing element.

[0031] The structural element being configured separately from the body frame can be understood in particular to mean that the structural element and the body frame are not configured integrally together. The structural element can therefore be a mounting part. In particular, when the body frame and the structural element are configured separately from each other, they are manufactured independently of each other. In particular, the structural element can be formed from a different material than the body frame.

[0032] In order to be able to design the installation space of the motor vehicle particularly advantageously, in particular to be able to keep the installation space particularly small, the invention provides that at least one sensor element is arranged in the receiving space of the marking lighting device, by means of which at least one acoustic signal from the motor vehicle surroundings can be detected.

[0033] In a further embodiment, at least one second sensor element, which is designed separately from the sensor element and is in particular acoustic, is arranged, by means of which acoustic signals from the surroundings of the motor vehicle can be detected or detected. The sensor elements are preferably designed in an identical manner. For example, the second sensor element is spaced apart from a sensor element, in particular the first sensor element. This can lead to direction recognition and / or distance recognition of acoustic signals emitted from the surroundings. This can, for example, particularly specifically filter out interfering noises, so that, for example, acoustic signals can be detected particularly reliably by means of the sensor element.

[0034] The second sensor element may be arranged in the receiving space, or the second sensor element may be arranged outside the receiving space, in particular outside the marking lighting device.

[0035] When the second sensor element is arranged outside the logo lighting device, it is preferably provided that the second sensor element is arranged in a second logo lighting device constructed separately from the logo lighting device, in particular in a second receiving space of the second logo lighting device that is different from the receiving space. This means that the second logo lighting device provided for illuminating the logo of the motor vehicle has, for example, a housing element, in particular called a second housing element, which at least partially delimits a receiving space, in particular called a second receiving space, of the second logo lighting device. In the second receiving space, for example, at least one lighting element, in particular called a second lighting element, of the second logo lighting device is arranged for illuminating the logo. It is preferably provided that two, for example exactly two, corresponding sensor elements are arranged in the corresponding receiving space of the corresponding logo lighting device.

[0036] For example, a cascade can be formed of two marking lighting devices, in particular of sensor elements of marking lighting devices, whereby spatial noise detection and in particular spatial noise filtering can be particularly improved. Here, the acoustic signal can be detected by means of four sensor elements, whereby spatial noise detection and / or noise filtering can be particularly improved, in particular even when the sensor elements are arranged symmetrically with respect to one another.

[0037] In another design, it is provided that the distance between the noise source emitting the acoustic signal and the motor vehicle, in particular the motor vehicle sub-area, can be determined or determined by means of an electronic computing device based on the acoustic signal detected by means of a sensor element. In other words, the distance between the noise source and the motor vehicle, in particular the motor vehicle sub-area, can be determined by means of an electronic computing device. When determining, for example, the distance is calculated. The motor vehicle sub-area can be understood as a reference point in particular. The reference point can be arranged inside the motor vehicle or on the outside of the motor vehicle. By determining a distance that can be particularly referred to as distance recognition, the acoustic signal can be filtered, for example, according to the determined distance. Therefore, for example, the particularly interfering background noise of another noise source that is different from the noise source and is particularly far away can be filtered out, that is, not considered. This means that the interfering noise can be particularly minimized. This can particularly improve the reliability for detecting or evaluating the acoustic signal.

[0038] Alternatively or additionally, it is provided that the direction in which the noise source is located with respect to the motor vehicle, in particular with respect to the motor vehicle subregion, can be detected or detected by means of the electronic computing device. This means that the direction in which the noise source is located starting from the motor vehicle, in particular the motor vehicle subregion, or is spaced from the motor vehicle, in particular the motor vehicle subregion, can be detected or detected. By determining the direction, which can be particularly referred to as direction identification, background noise or interference noise can be filtered out depending on the determined direction. In other words, during signal processing, directional sensitivity can be achieved while filtering interference noise.

[0039] In a further embodiment, it is provided that the wing element is pivotably held relative to the vehicle body frame between a closed position and at least one open position, in particular at least indirectly or directly on the vehicle body frame. In other words, the wing element is fastened, in particular at least indirectly or directly, to the vehicle body frame, wherein the wing element can be pivoted relative to the vehicle body frame between a closed position and an open position about a pivot axis. For example, in the closed position, an opening, for example a so-called flap opening, which is particularly defined by the vehicle body frame, is particularly completely closed by the wing element. For example, the opening is at least partially, in particular completely, released by the wing element in the open position. The opening is, for example, an access to an interior or cargo compartment of a motor vehicle.

[0040] Preferably, at least one coupling mechanism, in particular electrically and / or mechanically couplable or coupled to the wing element, is provided, by means of which the wing element can be pivoted or pivoted between a closed position and an open position according to an acoustic signal detected by means of a sensor element and / or a second sensor element. In other words, according to an acoustic signal detected by means of at least one of the sensor elements, the wing element can be pivoted about a pivot axis from a closed position to an open position and / or from an open position to a closed position. This means that the wing element, in particular the rear hatch, can be opened and / or closed by voice control. This makes it possible to open the wing element particularly cost-effectively, thereby particularly improving the comfort of the motor vehicle. For example, the wing element can be pivoted between a closed position and an open position by means of a coupling mechanism according to a variable detected by means of a sensor element and / or a second sensor element.

[0041] For example, it is provided that at least one control signal can be transmitted or transmitted to the coupling mechanism by means of an electronic computing device in accordance with an acoustic signal detected by means of at least one of the sensor elements or in accordance with a corresponding variable detected by means of at least one of the sensor elements to cause a pivoting of the wing element. Thus, the wing element can be opened and / or closed by means of the coupling mechanism in accordance with a control signal transmitted by the electronic computing device to the coupling mechanism. The coupling mechanism is preferably arranged outside the housing element. The electronic computing device can be arranged inside the housing element or outside the housing element.

[0042] Preferably, provision is made that an acoustic signal detected by means of at least one of the sensor elements is compared with at least one reference signal by means of an electronic computing device. Here, when a particularly predefined condition is met, for example when the detected acoustic signal corresponds to the reference signal, the wing element is pivoted between the closed position and the open position, for example by means of a coupling mechanism. The reference signal can be understood in particular as a reference voice signal, that is to say a reference voice message or a reference voice command. Preferably, when a particularly predefined criterion is not met, for example when the detected acoustic signal does not correspond to the reference signal, that is to say when the detected acoustic signal is, for example, different from the reference signal, the pivoting of the wing element between the closed position and the open position is stopped.

[0043] Preferably, provision is made that the comparison of the detected acoustic signal with the reference signal is performed when the determined distance has a first distance value or corresponds to the first distance value. Preferably, the comparison of the detected acoustic signal with the reference signal is stopped when the determined distance has a second distance value that is different from the first distance value, in particular greater than the first distance value, or corresponds to the second distance value.

[0044] Preferably, it is provided that when the determined direction has a first direction value or corresponds to a first direction value, the comparison of the detected acoustic signal with the reference signal is performed. Preferably, when the determined direction has a second direction value different from the first direction value or corresponds to the second direction value, the comparison of the detected acoustic signal with the reference signal is stopped.

[0045] For example, a sensor device is provided, which is especially designed separately from the identification lighting device, by means of which objects located in the surroundings and / or in the motor vehicle, especially different from noise sources, can be detected. The object is, for example, a key for the motor vehicle or the motor vehicle, especially a vehicle key. In particular, the distance between the object and the motor vehicle, especially a motor vehicle component, can be detected or ascertained by means of the sensor device.

[0046] Preferably, it is provided that the wing element is pivoted when the object is spaced apart from the motor vehicle by a first distance value or is located inside the motor vehicle. Preferably, the pivoting of the wing element is stopped when the object is spaced apart from the motor vehicle by a second distance value that is different from the first distance value, wherein the second distance value is preferably greater than the first distance value. The corresponding distance value can be understood in particular as a corresponding distance value detected by means of the sensor device. Therefore, the pivoting of the wing element can only be performed according to the detected acoustic signal when the object, in particular the key, is detected at least in the vicinity of the motor vehicle by means of the sensor device.

[0047] Preferably, provision is made that a comparison of the detected acoustic signal with a reference signal is performed as a function of the object detected by means of the sensor device. Provision is made, for example, that a comparison of the detected acoustic signal with a reference signal is performed when the difference between the determined distance and the determined spacing is less than a predefined threshold value. Preferably, the comparison of the detected acoustic signal with a reference signal is not performed if the difference between the determined distance and the determined spacing is greater than a predefined threshold value. Background noise, in particular interference noise, can thereby be particularly well filtered out.

[0048] Alternatively or additionally, it is provided, for example, that an object direction can be detected or ascertained by means of the sensor device, in which the object is located relative to the motor vehicle, in particular relative to a subarea of ​​the motor vehicle. It is preferably provided that a comparison of the detected acoustic signal with a reference signal is performed when the difference between the ascertained direction and the ascertained object direction is less than a predefined threshold value, in particular referred to as a second threshold value. Preferably, a comparison of the detected acoustic signal with a reference signal is not performed if the difference between the ascertained direction and the ascertained object direction is greater than a predefined threshold value. Background noise, which can be referred to as interfering noise, can thereby be particularly well filtered out.

[0049] A third aspect of the invention relates to a method for operating a motor vehicle having at least one identification lighting device, in particular according to the first aspect of the invention. The advantages and advantageous configurations of the first and second aspects of the invention can be regarded as advantages and advantageous configurations of the third aspect of the invention, and vice versa.

[0050] In the method, provision is made for detecting at least one acoustic signal from the surroundings of a motor vehicle by means of at least one sensor element, the sensor element being arranged in a receiving space at least partially, in particular completely, delimited by a housing element of an identification lighting device, in which at least one lighting element of the identification lighting device is arranged for illuminating an identification of the motor vehicle. The method may be referred to in particular as a method for operating an identification lighting device or as a method for detecting an acoustic signal of a motor vehicle. For example, the identification is illuminated by means of the lighting element.

[0051] The fourth aspect relates to a method for operating an arrangement system according to the second aspect of the invention. The advantages and advantageous designs of the first aspect of the invention and the second aspect of the invention as well as the third aspect of the invention shall be regarded as advantages and advantageous designs of the fourth aspect, and vice versa.

[0059] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0060] Figure 1 A motor vehicle 1 is shown in a schematic partial sectional view, which has an identification lighting device 2. Figure 1 The arrangement system 3 of the indicia lighting device 2 on the structural element 4 of the motor vehicle 1 is shown. The structural element 4 is designed as a wing element 5 in this embodiment, in particular as a tailgate. The motor vehicle 1 has at least one indicia 6, in particular a number plate, which is arranged or held, for example, on the wing element 5, in particular on the tailgate. The indicia lighting device 2 is provided to illuminate the indicia 6.

[0061] The structural element 4 is preferably designed separately from the body frame 7 of the motor vehicle 1. In particular, the structural element 4 is held directly on the body frame 7. The marking lighting device 2 is therefore held on the body frame 7 via the structural element 4. The marking lighting device 2 is arranged in particular on the outer side 8 of the motor vehicle 1, in particular on the body frame 7.

[0062] Figure 2The marking lighting device 2 is shown in a schematic partial view. The marking lighting device 2 has at least one housing element 9, which at least partially, in particular completely, delimits a receiving space 10. The housing element 9 can be constructed in a single piece or in multiple pieces. For example, the housing element 9 has a housing part 11. For example, a sealing element 12, which is constructed separately from the housing part 11, is arranged on the housing part 11. For example, the sealing element 12 is in particular directly against the body frame 7. Therefore, the housing element 9, in particular the housing part 11, is sealed relative to the body frame 7, for example, by the sealing element 12.

[0063] At least one lighting element 13 is arranged in the receiving space 10 and is provided for illuminating the logo 6 . Figure 2 In the embodiment shown, two, in particular exactly two, lighting elements 13, 14 are arranged in the receiving space 10 for illuminating the logo 6. The lighting elements 13, 14 are preferably spaced apart from one another. For example, the individual lighting elements 13, 14 are designed as corresponding LEDs.

[0064] In order to be able to design the installation space of motor vehicle 1 particularly advantageously, in particular to be able to keep the installation space particularly small, it is provided that at least one, in particular acoustic, sensor element 15, 16 is arranged in receiving space 10, by means of which at least one acoustic signal 17 from motor vehicle surroundings 18 can be detected or sensed. Figure 2 In the embodiment shown in , two, in particular exactly two sensor elements 15, 16 are arranged in the receiving space 10, wherein an acoustic signal 17 can be detected or detected by means of the sensor elements 15, 16. The respective sensor elements 15, 16 are designed, for example, as respective microphones. Here, the respective microphones are preferably designed as respective digital microphones. As a result, interfering influences, in particular compared to respective analog microphones, can be kept particularly low.

[0065] Acoustic signal 17 is emitted, for example, by a noise source 19 located in surroundings 18 of motor vehicle 1. Noise source 19 is, for example, a person.

[0066] Figure 3 A schematic method diagram shows a method for operating a motor vehicle 1 , in particular for operating an identification lighting device 2 . In the method, at least one acoustic signal 17 from a surrounding 18 of the motor vehicle 1 is detected by means of sensor elements 15 , 16 respectively arranged in the receiving space 10 .

[0067] It is preferably provided that the respective sensor elements 15, 16 are arranged on a carrier element 20 which is designed separately from the housing element 9, in particular a common carrier element, which is designed, for example, as a printed circuit board. For example, the respective sensor elements 15, 16 are mechanically and / or electrically connected to the carrier element 20. It is preferably provided that the respective lighting elements 13, 14 and the respective sensor elements 15, 16 are arranged on the carrier element 20.

[0068] In a further embodiment, it is provided that the respective sensor elements 15, 16 have at least one respective opening 21, 22 provided for the entry of sound into the respective interior of the respective sensor element 15, 16. This means that the first sensor element of the sensor elements 15 has a first opening of the opening 21 and the second sensor element 16 has a second opening 22. The respective openings 21, 22 are preferably each covered by a respective diaphragm 23, in particular in a liquid-tight manner.

[0069] The marking lighting device 2 has, for example, at least two, in particular, exactly two through holes, which are respectively assigned to a corresponding sensor element of the sensor elements 15, 16, in particular corresponding openings 21, 22 or diaphragm 23. The first through hole of the through holes is assigned to the first sensor element 15. The second through hole of the through holes is assigned to the second sensor element 16. Via the corresponding through holes, the corresponding sensor elements 15, 16, in particular the corresponding openings 21, 22 or the corresponding diaphragm 23 assigned to the corresponding through holes are connected or connectable to the surroundings 18 in a sound-transmitting and / or sound-transmissive manner. Therefore, the corresponding through holes are provided for the sound, in particular the sound of the acoustic signal 17, to enter the corresponding inner cavity of the corresponding sensor element 15, 16.

[0070] For example, the corresponding through hole can be shaped unevenly or irregularly, especially in its axial direction, for example in the radial direction and / or in the circumferential direction. Thus, the corresponding through hole can have an uneven radius, for example, especially along its axial direction. This means that the corresponding through hole can be shaped like a trumpet, for example. As a result, the acoustic signal 17 can be detected or received particularly well by means of the corresponding sensor element 15, 16.

[0071] Figure 4 The inscription lighting device 2 is shown in a schematic partial sectional view. The inscription lighting device 2 has, for example, at least one, in particular transparent, lens 32 .

[0072] For example, corresponding openings 21, 22 are arranged in the lens 32. The lens 32 therefore has openings 21, 22. In this context, corresponding openings 21, 22 may be understood to be corresponding holes in the lens 32, in particular.

[0073] Figure 5A schematic partial cross-sectional view of a marking lighting device 2 according to another embodiment is shown, wherein the marking lighting device 2, in particular the lens 32, does not have corresponding openings 21, 22, i.e., there are no corresponding openings 21, 22. For example, the lens 32 is particularly thinly constructed in the corresponding partial regions 21a, 22a relative to the other partial regions of the lens 32, in particular at least indirectly or directly adjacent to the corresponding partial regions 21a, 22a. This means that the lens 32 can be locally constructed with particularly thin walls. Therefore, the wall thickness of the lens in the corresponding partial regions 21a, 22a of the lens 32 is, for example, thinner than in the other partial regions of the lens 32. Thus, the diaphragm 23 and in particular the openings 21, 22 can be omitted. Therefore, the corresponding partial regions 21a, 21a of the lens 32 can be provided to allow sound to enter the corresponding inner cavity of the corresponding sensor element 15, 16. This means that sound can be transmitted to the inner cavity of the corresponding sensor element 15, 16 through the corresponding partial regions 21a, 22a. That is to say, for example, the opening 21 can be "replaced" by the partial region 21a, and the opening 22 can be "replaced" by the partial region 22a. Thus, the respective sensor element 15, 16 can be "heard" via the respective partial region 21a, 22a or via the particularly thin-walled lens 32. For example, the wall thickness of the lens 32 in the respective partial region 21a, 22a is 0.5 mm. For example, the wall thickness of the lens 32 in the other partial regions is 2 mm.

[0074] In a further embodiment, the respective lighting elements 13, 14, in particular the carrier element 20, are arranged in a first plane 24 and the respective openings 21, 22 are arranged in a second plane 25 different from the first plane 24, in particular spaced apart from the first plane 24. Preferably, the carrier element 20 extends in the first plane 24.

[0075] For example, the motor vehicle 1 has a logo support, by which the logo 6 is held, in particular directly, on the structural element 4, in particular on the tailgate. Preferably, the logo lighting device 2, in particular the corresponding lighting elements 13, 14 and / or the corresponding sensor elements 15, 16 are arranged above the logo support, in particular the logo 6, in the vehicle height direction of the motor vehicle 1. For example, the logo lighting device 2, in particular the housing element 9, extends obliquely or perpendicularly to the logo support, in particular to the logo 6.

[0076] For example, the motor vehicle 1 has at least one second identification lighting device which is designed separately from the identification lighting device 2, in particular spaced apart from the identification lighting device 2, for example in the vehicle transverse direction of the motor vehicle 1. Preferably, the second identification lighting device has at least two, in particular exactly two sensor elements, by means of which acoustic signals 17 from the surroundings 18 of the motor vehicle 1 can be detected. This means that, for example, two of the sensor elements can be integrated in each case in the respective identification lighting device, in order to be able to realize a cascade of four sensor elements, in particular in the rear region of the motor vehicle 1.

[0077] In a further embodiment, at least one electronic computing device 26 is provided, by means of which a distance 27 between a noise source 19 emitting the acoustic signal 17 and the motor vehicle 1 can be ascertained or determined as a function of the acoustic signal 17 detected by means of the respective sensor element 15, 16. Alternatively or additionally, provision is made for the electronic computing device 26 to ascertain or determine a direction 28 in which the noise source 19 is located with respect to the motor vehicle 1 as a function of the acoustic signal 17 detected by means of the respective sensor element 15, 16.

[0078] Preferably, it is provided that the wing element 5, in particular the tailgate, is held pivotably relative to the body frame 7 between a closed position 29 and at least one open position 30. In a further embodiment, at least one coupling mechanism 31 is provided which can be coupled or is coupled to the wing element 5, in particular the tailgate, by means of which the wing element 5, in particular the tailgate, can be pivoted or is pivoted between the closed position 29 and the open position 30 depending on the acoustic signal 17 detected by the corresponding sensor element 15, 16, in particular depending on the ascertained distance 27 and / or depending on the ascertained direction 28.
