Description

The invention relates to a detection device for a motor vehicle according to the features of patent claim 1. The invention also relates to an arrangement of a detection device on a component of a motor vehicle according to the features of patent claim 4.

From the DE 10 2017 200 361 A1 a detection device for a motor vehicle with a housing element is already known. The housing element at least partially delimits a receiving space. At least three sensor elements are arranged in the receiving space, by means of which at least one acoustic signal from the surroundings of the motor vehicle can be detected.

Furthermore, the DE 10 2004 045 690 A1 a device for determining external sound sources in the area surrounding a motor vehicle, which has a microphone array arranged on the motor vehicle with a plurality of microphones for recording ambient noise of a motor vehicle and an evaluation device for evaluating the microphone signals.

The object of the invention is to create a detection device for a motor vehicle and an arrangement of a detection device on a component of a motor vehicle, so that an acoustic signal from the surroundings of the motor vehicle can be detected particularly well.

This object is achieved according to the invention by a detection device for a motor vehicle having the features of patent claim 1 and by an arrangement of a detection device on a component of a motor vehicle with the features of patent claim 4 . Advantageous configurations of the invention are the subject matter of the dependent patent claims and the description.

A first aspect of the invention relates to a detection device for a motor vehicle. The motor vehicle is preferably designed as a motor vehicle, in particular as a passenger car, commercial vehicle or truck.

The detection device has at least one housing element which at least partially, in particular completely, delimits a 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 thus at least partially, in particular completely, covered by the housing element. The receiving space is part of the detection device. This means that the detection device encompasses the receiving space.

The detection device has at least three, for example four, in particular exactly four, in the receiving space, in particular acoustic, sensor elements, by means of which, in particular in the installation position of the detection device in the motor vehicle, at least one acoustic signal from an environment of the motor vehicle can be or is detected. Thus, the sensor elements are arranged within the housing element. This means that the sensor elements can be integrated in the housing element, which in particular can be referred to as a housing. The acoustic signal can be understood in particular as a noise from the surroundings of the motor vehicle. This means that an acoustic signal or noise emitted by a noise source located in the vicinity of the motor vehicle can be detected by means of the sensor elements. The acoustic signal, in particular in the form of sound or sound waves, can thus be emitted by the noise source and received or detected by the sensor elements. The noise source can be understood in particular as a sound source. The respective sensor element is designed, for example, as a respective microphone.

For example, at least one variable characterizing the acoustic signal can be detected by means of the sensor elements. For example, the detected variable is transmitted by the sensor elements to an electronic computing device, and the acoustic signal can be determined or evaluated by the electronic computing device depending on the detected or transmitted variable.

The noise wave is preferably a person, in particular a person located in the vicinity of the motor vehicle. The acoustic signal can thus be a noise emitted by the person, in particular caused by the person. The acoustic signal or the noise is preferably a voice, in particular a human voice, of the person. The, in particular human, voice can be understood in particular as sound generated by vocal folds in the larynx of the person and modulated in the vocal tract, in particular the oral cavity and/or pharyngeal cavity and/or nasal cavity of the person. Thus, the acoustic signal or the noise is a voice command, for example.

The detection device is on an outside, in particular via the housing element a body shell of the motor vehicle, in particular at least indirectly or directly on the component. This means that the detection device is arranged or fastened on the outside of the bodyshell when the motor vehicle is in the fully manufactured state. The detection device can be held or fastened at least indirectly to the shell, in particular via the component. The detection device can thus be or is arranged outside of the shell. The shell can be understood in particular as a body of the motor vehicle. The body shell is preferably designed as a body, in particular a self-supporting body.

• Beispielweise sind ein erstes der Sensorelemente und ein zweites der Sensorelemente in der Erstreckungsrichtung in einem ersten Abstand voneinander beabstandet. Beispielweise sind das zweite Sensorelement und ein drittes der Sensorelemente in der Erstreckungsrichtung in einem von dem ersten Abstand unterschiedlichen, zweiten Abstand voneinander beabstandet. Beispielsweise ist das zweite Sensorelement in der Erstreckungsrichtung zwischen dem ersten Sensorelement und dem dritten Sensorelement angeordnet. Somit handelt es sich bei dem ersten und dem zweiten Sensorelement um jeweilige, insbesondere unmittelbar, benachbarte Sensorelemente. Bei dem ersten und dem dritten Sensorelement handelt es sich somit insbesondere um keine jeweiligen, insbesondere unmittelbar, benachbarten Sensorelemente. Bei dem zweiten und dem dritten Sensorelement handelt es sich um jeweilige, insbesondere unmittelbar, benachbarte Sensorelemente. Insbesondere schließt sich das zweite Sensorelement entlang der Erstreckungsrichtung in dem ersten Abstand zumindest mittelbar an das erste Sensorelement an. Insbesondere schließt sich das dritte Sensorelement entlang der Erstreckungsrichtung in dem zweiten Abstand zumindest mittelbar an das zweite Sensorelement an. Beispielweise sind das dritte Sensorelement und das vierte der Sensorelemente in der Erstreckungsrichtung in einem von dem ersten und/oder dem zweiten Abstand unterschiedlichen, dritten Abstand voneinander beabstandet. Somit handelt es sich bei dem dritten und dem vierten Sensorelement um jeweilige, insbesondere unmittelbar, benachbarte Sensorelemente. Bei dem zweiten und dem vierten Sensorelement und bei dem ersten und dem vierten Sensorelement handelt es sich insbesondere um keine jeweiligen, insbesondere unmittelbar, benachbarten Sensorelemente. Insbesondere schließt sich das vierte Sensorelement entlang der Erstreckungsrichtung in dem dritten Abstand zumindest mittelbar an das dritte Sensorelement an.

In order to be able to detect the acoustic signal from the surroundings of the motor vehicle particularly well, it is provided that the sensor elements are arranged in pairs, in particular directly, adjacent and in pairs spaced apart from one another along a direction of extent and have different distances from one another in pairs, running in the direction of extent. In other words, respective distances relative to the extension direction between two respective sensor elements that are adjacent in the extension direction, in particular directly, are different from one another. In other words, the sensor elements are distributed asymmetrically along the direction of extent, in particular in the receiving space or the housing element. This can be understood to mean the following in particular:

• For example, a first of the sensor elements and a second of the sensor elements are spaced apart from one another by a first distance in the extension direction. For example, the second sensor element and a third of the sensor elements are spaced apart from one another in the extension direction by a second distance that is different from the first distance. For example, the second sensor element is arranged between the first sensor element and the third sensor element in the extension direction. The first and the second sensor element are therefore respective, in particular immediately adjacent, sensor elements. The first and the third sensor element are therefore in particular not respective, in particular directly adjacent sensor elements. The second and the third sensor element are respective, in particular immediately adjacent, sensor elements. In particular, the second sensor element is at least indirectly adjacent to the first sensor element along the direction of extent at the first distance. In particular, the third sensor element is at least indirectly adjacent to the second sensor element along the extension direction at the second distance. For example, the third sensor element and the fourth of the sensor elements are spaced apart from one another in the extension direction by a third distance that is different from the first and/or the second distance. The third and the fourth sensor element are therefore respective, in particular immediately adjacent, sensor elements. The second and the fourth sensor element and the first and the fourth sensor element are in particular not respective, in particular directly adjacent sensor elements. In particular, the fourth sensor element is at least indirectly adjacent to the third sensor element along the extension direction at the third distance.

The direction of extent of the detection device can be a direction of transverse extent of the detection device or a direction of longitudinal extent of the detection device. Alternatively, the direction of extent can run obliquely or perpendicularly to the direction of transverse extent and/or to the direction of longitudinal extent of the detection device. For example, the extension direction of the detection device in the installation position of the detection device in the motor vehicle can run parallel to the longitudinal direction of the vehicle and/or to the transverse direction of the vehicle and/or to the vertical direction of the motor vehicle. Alternatively, the extension direction of the detection device can run obliquely or perpendicularly to the longitudinal direction of the vehicle and/or to the transverse direction of the vehicle and/or to the vertical direction of the vehicle.

The invention is based in particular on the following findings and considerations: Vehicles, in particular motor vehicles, can be operated from the outside with mechanical and/or electrical elements. Here, for example, handles, buttons, switches, radio remote controls or specific movements of a person can be used to operate. For example, a wing element, in particular a tailgate, of the motor vehicle can be operated via haptic elements, such as buttons, emblem actuation or the like. Alternatively or in addition, the wing element, in particular the tailgate, can be operated via internal buttons, remote control or the targeted movement of the person. The targeted movement of the person can in particular involve contactless operation, that is to say a contactless movement in which the motor vehicle is not touched by the person. The targeted movement can in this case, for example, be a movement of a foot of the person, referred to in particular as a foot kick. Operating or opening the motor vehicle, in particular the wing element, for example the tailgate, can in particular be referred to as a smart opener (SMO). The tailgate can be brought about in particular by a kicking movement of the foot under a rear bumper of the motor vehicle. Operating by means of the targeted movement in the form of a non-contact operating point (smart opener) can be unintuitive for the person and particularly error-prone. This can have a negative effect on the comfort of the motor vehicle.

In contrast, using the detection device according to the invention, the motor vehicle can be operated from outside, ie from the environment, by voice control or by voice command. This means that the motor vehicle can be voice-controlled by the person in the vicinity. Thus, for example, the wing element and/or a window of the motor vehicle can be opened and/or closed by the person using voice control or voice control. As a result, the motor vehicle can be controlled or operated from the outside with particularly little effort, in particular particularly intuitively. In particular, the casement element and/or the window can be opened or closed with particularly little effort, in particular particularly intuitively. As a result, the comfort of the motor vehicle can be particularly increased. Because the detection device has at least the three sensor elements, and in particular the sensor elements have different distances, a direction detection and/or a distance detection of the acoustic signal can be made possible, in particular particularly reliably and/or particularly precisely. As a result, for example, background noise from the area surrounding the motor vehicle can be filtered out in a targeted manner. As a result, the detection of the acoustic signal can be particularly improved; in particular, the acoustic signal can be detected particularly precisely and/or particularly reliably. The motor vehicle, in particular the sash element and/or the window, can thus be operated particularly reliably by the person. As a result, the comfort of the motor vehicle can be particularly increased.

The wing element can be understood, for example, as a flap element that is referred to in particular as a flap. For example, the flap element is a tailgate or a door, in particular a side door, of the motor vehicle.

In a further refinement, provision is made for the sensor elements to be arranged on an imaginary straight line in the direction of extent. This means that the straight line runs through the sensor elements. In other words, the sensor elements are arranged in a row, in particular in the direction of extension, that is to say in a row, in the receiving space. This can be understood to mean, for example, that the sensor elements are combined in the form of a sensor element array referred to in particular as a microphone array. As a result, for example, the direction of the acoustic signal can be identified with particular precision. The detection of the acoustic signal can thus be particularly improved.

In a further refinement, it is provided that the sensor elements are arranged, in particular directly, on a carrier element which is formed separately from the housing element and is in particular common. In other words, the sensor elements are held or fastened, in particular directly, to the carrier element. This means that the sensor elements can be installed together on the carrier element, in particular the circuit board. As a result, an installation space of the detection device can be designed in a particularly advantageous manner, in particular can be kept particularly small. The carrier element is designed, for example, as a circuit board. The carrier element is preferably, in particular completely, arranged in the receiving space.

Provision is preferably made for the housing element to be liquid-tight, in particular watertight. 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 off or is sealed off from the surroundings of the detection device. The liquid tightness, in particular the water tightness, can thus be brought about by means of the sealing element. As a result, the detection device, in particular the housing element, can be kept particularly tight. As a result, the sensor elements can be particularly well protected, for example, against damage caused by moisture. The detection device can thus be arranged or installed in a wet area of the motor vehicle, in particular in the vehicle exterior.

Provision is preferably made for the respective sensor element to have at least one respective opening provided for sound entry into a respective interior space of the sensor element. In other words, the acoustic signal via the respective opening to the Detection of the acoustic signal in the interior of the respective sensor element, in particular acoustically, transferrable. This means that the opening is provided for the sound entry of the acoustic signal into the respective sensor element, in particular into the respective interior space.

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

The membrane is preferably designed to be sound-transmitting or sound-transmitting. The membrane can therefore be referred to as a sound membrane in particular. This means that sound waves acting on the membrane from a first side, in particular the acoustic signal, can be transmitted via the membrane to a second side of the membrane that is different from the first side, in particular that is opposite the first side. The first side is preferably an outside of the membrane or of the sensor element. The second side is preferably an inside of the membrane or of the sensor element. This means that the second side preferably faces the interior space and the first side preferably faces away from the interior space.

Provision is preferably made for the carrier element to be arranged in a first plane and for the respective opening to be arranged in a second plane which is different from the first plane, in particular spaced apart from the first plane. In other words, the respective opening is at a distance from the carrier element, in particular obliquely or perpendicularly to the direction in which the detection device extends. As a result, the acoustic signal can be detected particularly well, in particular error-free or particularly resistant to interference, by means of the respective sensor element.

A second aspect of the invention relates to an arrangement of at least one detection device having a housing element and at least three sensor elements, for example four, in particular exactly four, sensor elements, in particular according to the first aspect of the invention, on, in particular in, a component of a motor vehicle. Advantages and advantageous configurations of the first aspect of the invention are to be regarded as advantages and advantageous configurations of the second aspect of the invention and vice versa.

The housing element delimits a receiving space at least partially, in particular completely, in which the sensor elements are arranged. At least one acoustic signal from the surroundings of the motor vehicle can be detected by means of the sensor elements.

The detection device is arranged on an outside of a shell of the motor vehicle. In other words, the detection device is located on the outside of the shell. This means that the detection device is not arranged in an interior of the motor vehicle, referred to in particular as the vehicle interior or as the passenger cell. Thus, the detection device is spaced from the interior. The detection device can be held, in particular via the housing element, on the outside of the shell, in particular at least indirectly or directly, on the component and/or on the shell.

In order to be able to detect the acoustic signal from the environment particularly well, provision is made for the sensor elements to be arranged in pairs, in particular directly, adjacent and in pairs spaced apart from one another in a direction of extent of the detection device, and for pairs to have different distances from one another running in the direction of extent.

Provision is preferably made for the component to be formed separately from the shell. This means that the component and the shell are not formed together in one piece. The component can thus be an add-on part. In particular, the shell and the component are manufactured separately from one another. For example, the component is formed from a material that is different from the shell.

The detection device can be integrated into the component, it being possible for the detection device to be held or fastened at least indirectly to the body shell via the component. This enables direct acoustic access of the respective sensor element, in particular without a cover, to the environment, which is referred to in particular as the exterior of the motor vehicle. Furthermore, the sensor elements can be particularly inconspicuous, in particular more on the outside of the shell, are integrated into the vehicle. In particular, an installation space of the motor vehicle can be designed particularly advantageously. For example, existing installation space of the component can be used to arrange the detection device. This means that the installation space of the motor vehicle can be designed particularly efficiently.

In a further embodiment, it is provided that the structural element as a wing element, in particular as a wing element part of the wing element, or as an air guiding element, in particular as an air guiding element part of the air guiding element, or as an exterior mirror, in particular as an exterior mirror part of the exterior mirror, or as a sill, in particular as a sill part of the sill, or is designed as a cover element, in particular as a cover element part of the cover element. In other words, the wing element, the air guiding element, the exterior mirror, the sill or the cover element is formed at least partially, in particular completely, by the component. The detection device can thus be arranged on, in particular in, the wing element, the air guiding element, the exterior mirror, the sill or the cover element. As a result, the installation space of the motor vehicle can be designed in a particularly advantageous manner. In particular, the detection device can be accommodated in the motor vehicle in a particularly space-saving manner.

The wing element is designed, for example, as a door, in particular as a side door, or as a flap, in particular as a tailgate or front flap. The component can thus be designed as a tailgate, in particular as a tailgate part of the tailgate. In particular, the front flap can be operated at least partially electrically if the motor vehicle has a loading space, in particular referred to as a frunk, which is covered or can be covered by the front flap. In this case, the use of voice control can be particularly attractive since, for example, sensible haptic alternatives cannot be present in the front area of the motor vehicle. The cover element is designed, for example, as a strip, in particular as a window strip. For example, the bar or the window bar is a decorative bar. The air guiding element is designed, for example, as a spoiler, in particular as a rear spoiler. For example, while the motor vehicle is being driven, the air guiding element is arranged in an air flow that flows against or around the motor vehicle. This means that the air guiding element is acted upon by the air flow when the motor vehicle is moving, in particular the air flow flows against or around it. The sill is, for example, a side sill.

In particular when the component is designed as a wing element, in particular as a tailgate, provision is preferably made for the detection device to be located in the area of a lower end, in particular in the area of a lower edge of the wing element, in particular the tailgate, is arranged. In other words, the detection device is located in the vertical direction of the vehicle in the region of the lower end, in particular the lower edge, of the wing element. In other words, the detection device is arranged in the vehicle vertical direction of the motor vehicle in the area of the lower end of the wing element. As a result, an installation space of the wing element, in particular of the tailgate, can be designed in a particularly advantageous manner. The lower end of the wing element can in particular be understood to mean a lower end region of the wing element in relation to the vertical direction of the vehicle. For example, the lower end is a handle strip of the wing element. Thus, the component can be designed in particular as the grip strip of the wing element.

For example, the detection device is designed as a module. The module can preferably be arranged, in particular integrated, in the component, in particular in the wing element and/or the air guiding element and/or in the exterior mirror and/or in the rocker panel and/or in the cover element.

In a further refinement, it is provided that the detection device is arranged in a receiving area which is delimited, in particular directly, at least partially, in particular completely, by a wall formed separately from the detection device, in particular of the component. In other words, the receiving area is at least partially, in particular completely, surrounded by the wall, in particular directly. The receiving area is designed as a wet area, for example. Thus, the detection device can be arranged in the wet area. For example, the receiving area, in particular the wet area, is separated by the wall from a dry area that is different from the receiving area, in particular the wet area. For example, the component includes the wall. Thus, the wall can be designed as a wall area of the component. Alternatively, the wall can be formed separately from the component. The wall can, for example, be part of the shell or part of a be a component of the motor vehicle that is designed separately from the shell.

Provision is preferably made for the sensor elements to be connected, at least indirectly or directly, to one, in particular precisely one, in particular electrical connecting device which extends at least in regions outside of the housing element. In other words, the connecting device is arranged at least partially outside the housing element. The connection device is provided for signal transmission between the sensor elements and a component of the motor vehicle, in particular an electrical and/or electronic component, which is in particular configured separately from the detection device and is arranged outside the recording area. In other words, the sensor elements are signal-transmitting or electrically connectable or connected via the connecting device to the component arranged outside the receiving area. The signal transmission is, for example, data transmission. The connection device can thus be provided for data transmission between the sensor elements and the component. This means that the sensor elements can be or can be connected to the component in a data-transmitting manner via the connection device. Alternatively, the connection device can be provided, for example, for the, in particular electrical, energy supply or for the power supply of the sensor elements. The component is arranged in the dry area, for example.

The connecting device preferably comprises one line element, in particular exactly one line element, in particular an electrical line element, which is designed, for example, as a cable. For example, the connecting device includes at least one, in particular electrical, connection element, which is designed, for example, as a plug connector. For example, the line element is or can be connected to the sensor elements electrically and/or in a data-transmitting manner via the connection point.

In a further refinement, a sealing element is provided which covers the connecting device, in particular the connection element, at least in regions and rests, in particular directly, on the housing element and the wall, with which the housing element can be sealed or is sealed against the wall. In other words, the sealing element surrounds at least one longitudinal region of the connecting device, in particular the connection element, for example in the circumferential direction of the connecting device, at least partially, in particular completely. The connecting device, in particular the connection element, can thus be guided through the sealing element. In other words, the housing element is supported on the wall, in particular directly, via the sealing element. A sealing effect between the housing element and the wall can thus be brought about by means of the sealing element. As a result, the housing element can be sealed off, in particular directly, by means of the sealing element from the wall, in particular from the dry area. In particular, the connection device, in particular the line element and/or the connection element, can be protected from moisture. For example, the sealing element is designed as a grommet. The connector may be spaced from the sealing member or the connector may directly contact the sealing member. Thus, the sealing element may or may not rest against the connecting device. The sealing element is preferably formed from a material that is different from the housing element and/or the connecting device.

Alternatively, a first sealing element covering the connecting device, in particular the line element and/or the connection element, can be provided in some areas and resting, in particular directly, on the housing element and the connecting device. In other words, the first sealing element surrounds a longitudinal region, in particular referred to as the first longitudinal region, of the connecting device, in particular the line element and/or the connection element, for example in the circumferential direction of the connecting device, in particular directly, with the sealing element preferably surrounding the housing element and the connecting device, in particular the Line element and / or the connection element, in particular directly touched. Thus, the connecting device, in particular the longitudinal area, can be arranged at least partially within the first sealing element or can be passed through the second sealing element. In other words, the connecting device, in particular the line element, is supported on the housing element via the first sealing element. By means of the first sealing element, the housing element can be sealed against the connecting device, in particular the line element and/or the connection element. In other words, a sealing effect for sealing the housing element against the connecting device can be or is brought about by means of the first sealing element.

A second sealing element is preferably provided that covers the connecting device, in particular the line element and/or the connecting element, in some areas, butts against the wall and the connecting device, in particular the line element and/or the connecting element, in particular directly, and is spaced apart from the first sealing element . In other words, the second sealing element surrounds a second longitudinal area of the connecting device, in particular the line element, spaced apart from the first length area, for example in the circumferential direction of the connecting device, in particular the line element, with the second sealing element preferably touching the wall and the connecting device, in particular directly. Thus, the connecting device, in particular the second length region, can be arranged at least partially within the second sealing element or passed through the second sealing element. In other words, the connecting device, in particular the line element, is supported or can be supported on the wall, in particular directly, via the second sealing element. The connecting device, in particular the line element, can be sealed off or sealed against the wall by means of the second sealing element. In other words, a sealing effect for sealing the connecting device, in particular the line element, against the wall, in particular against the dry area, can be or is brought about by means of the second sealing element. The housing can thus be sealed off from the connecting device via the first sealing element and sealed off from the wall, in particular from the dry area, via the second sealing element. The first and/or the second sealing element is designed, for example, as a respective grommet. For example, the connecting device is at least partially arranged in the wet area. The first and/or the second sealing element is preferably formed from a material that is different from the housing element and/or the connecting device and/or the wall.

In a further refinement, it is provided that the wing element is held on the shell so that it can pivot between the closed position and at least one open position relative to the shell, in particular at least indirectly or directly. In other words, the wing element is fastened, in particular at least indirectly or directly, to the shell, the wing element being pivotable about a pivot axis between the closed position and the open position relative to the shell. For example, in the closed position, an opening, which is in particular delimited by the shell and is referred to as a flap opening, for example, is closed, in particular completely, by the wing element. For example, the opening in the open position is at least partially, in particular completely, uncovered by the wing element. The opening is, for example, access to an interior or to a loading space of the motor vehicle.

At least one, in particular electrical and/or mechanical, coupling device that can be or is coupled to the wing element, in particular electrically and/or mechanically, is preferably provided, by means of which the wing element moves between the closed position and the open position depending on the acoustic signal detected by the respective sensor element is or will be pivotable. In other words, the wing element can be pivoted from the closed position to the open position and/or from the open position to the closed position depending on the acoustic signal detected by the respective sensor element, in particular about the pivot axis. This means that the wing element, in particular the tailgate, can be opened and/or closed by voice control. As a result, the wing element can be opened with particularly little effort, in particular as a result of which the comfort of the motor vehicle can be particularly increased. For example, the wing element can be pivoted between the closed position and the open position by means of the coupling device depending on the variable detected by means of the respective sensor element.

For example, an electronic computing device is provided, by means of which, depending on the acoustic signal detected by the respective sensor element or depending on the respective variable detected by the respective sensor element, at least one control signal can be or will be transmitted to the coupling device for causing the pivoting of the wing element. The wing element can thus be opened and/or closed by means of the coupling device depending on the control signal transmitted from the electronic computing device to the coupling device.

The coupling device is preferably arranged outside the housing element, in particular outside the receiving area. The electronic computing device can be arranged inside the housing element or outside the housing element, in particular outside the receiving area. In particular, if the electronic arithmetic unit is arranged inside the housing element, i.e. arranged inside the receiving space, at least a first processing of the acoustic signal detected by means of the respective sensor element can take place, for example directly on the circuit board, by means of the electronic arithmetic unit. At least one result signal, for example the control signal, can be determined by means of the electronic computing device depending on the acoustic signal detected, it being possible for the result signal to be sent or transmitted by the electronic computing device to a second electronic computing device configured separately from the electronic computing device. The result signal is, for example, a digital signal, in particular a digital output BUS signal. The second electronic computing device is arranged, for example, outside the housing element, in particular outside the receiving area. The second electronic arithmetic unit can be part of the coupling device or the second electronic arithmetic unit can be formed separately from the coupling device and in particular be connected or connectable to the coupling device for data transmission.

In a further embodiment, it is provided that by means of the electronic computing device and/or by means of the second electronic computing device, depending on the acoustic signal detected by means of the respective sensor element, a distance between the noise source emitting the acoustic signal and the motor vehicle, in particular a partial area of the motor vehicle, can be determined or is being determined. In other words, a distance between the noise source and the motor vehicle, in particular the partial area of the motor vehicle, can be determined using the first electronic computing device and/or the second electronic computing device. In the determination, the distance is calculated, for example. The partial area of the motor vehicle can be understood in particular as a reference point. The reference point can be arranged inside the motor vehicle or on an outside of the motor vehicle. By determining the distance, which can in particular be referred to as distance detection, the respective acoustic signal can be filtered, for example, depending on the determined distance. Thus, for example, in particular disturbing background noises from further noise sources, in particular those that are particularly far away and different from the noise source, can be filtered out, ie not taken into account. This means that background noise can be particularly minimized. As a result, reliability for detecting or evaluating the acoustic signal can be particularly increased.

Alternatively or additionally, the electronic computing device and/or the second electronic computing device can be used to detect or detect a direction in which the noise source is located in relation to the motor vehicle, in particular the partial area of the motor vehicle. This means that a direction can be detected or is detected in which the noise source is located starting from the motor vehicle, in particular the partial area of the motor vehicle, or is at a distance from the motor vehicle, in particular the partial area of the motor vehicle. By determining the direction, which can in particular be referred to as direction detection, the background noise or the interference noise can be filtered out depending on the determined direction. This means that directional sensitivity can be enabled during signal processing while noise is filtered out at the same time.

It is preferably provided that the acoustic signal detected by means of the respective sensor element is compared with at least one reference signal by means of the first electronic computing device and/or by means of the second electronic computing device. The wing element is pivoted, for example, by means of the coupling device between the closed position and the open position when a particular predefined criterion is met, for example when the detected acoustic signal corresponds to the reference signal. The reference signal can be understood in particular as a reference speech signal, that is to say a reference speech message or a reference speech command. Preferably, the pivoting of the wing element between the closed position and the open position does not take place if the, in particular predefined, criterion is not met, for example if the detected acoustic signal does not correspond to the reference signal, i.e. if the detected acoustic signal differs from the reference signal, for example.

Provision is preferably made for the comparison of the detected acoustic signal with the reference signal to be carried out if the determined distance has a first distance value or corresponds to the first distance value.

The comparison of the detected acoustic signal with the reference is preferably omitted limit signal if the determined distance has a second distance value that differs from the first distance value, in particular is greater than the first distance value, or corresponds to the second distance value.

Provision is preferably made for the comparison of the detected acoustic signal with the reference signal to be carried out if the determined direction has a first direction value or corresponds to the first direction value. The comparison of the detected acoustic signal with the reference signal is preferably omitted if the determined direction has a second direction value that differs from the first direction value or corresponds to the second direction value.

For example, a sensor device is provided, in particular designed separately from the detection device, by means of which an object located in the environment and/or in the motor vehicle, in particular different from the noise source, can be detected. The object is, for example, a key, referred to in particular as a vehicle key, for the motor vehicle or the motor vehicle. In particular, a distance between the object and the motor vehicle, in particular the motor vehicle part, can be detected or determined by means of the sensor device.

Provision is preferably made for the wing element to be pivoted when the object is at a first distance from the motor vehicle or is located inside the motor vehicle. The pivoting of the wing element preferably does not occur if the object is at a distance from the motor vehicle at a second distance value that differs from the first distance value, the second distance value preferably being greater than the first distance value. The respective distance value can be understood in particular as a respective distance value detected by means of the sensor device. The pivoting of the wing element can therefore only be carried out as a function of the detected acoustic signal if the sensor device detects that the object, in particular the key, is at least in the vicinity of the motor vehicle.

It is preferably provided that the comparison of the detected acoustic signal with the reference signal is carried out as a function of the object detected by the sensor device. It is provided, for example, that the comparison of the detected acoustic signal with the reference signal is carried out if a difference between the determined distance and the determined distance is smaller than a predefined threshold value. The comparison of the detected acoustic signal with the reference signal is preferably omitted if the difference between the determined distance and the determined distance is greater than the predefined threshold value. As a result, the background noises, referred to in particular as background noises, can be filtered out particularly well.

Alternatively or additionally, it is provided, for example, that the sensor device can be used to detect or determine an object direction in which the object is located in relation to the motor vehicle, in particular to the partial area of the motor vehicle. Provision is preferably made for the comparison of the detected acoustic signal with the reference signal to be carried out if a difference between the determined direction and the determined object direction is smaller than a predefined threshold value, referred to in particular as a second threshold value. The comparison of the detected acoustic signal with the reference signal is preferably omitted if the difference between the determined direction and the determined object direction is greater than the predefined threshold value. As a result, the background noises, referred to in particular as background noises, can be filtered out particularly well.

In the exemplary embodiment, the housing element 5 comprises a first housing part 7 and a second housing part 8 which is formed separately from the first housing part 7 and is connected, in particular directly, to the first housing part 7. The housing element 5, which is referred to in particular as the housing, is therefore in several parts, in particular in two parts educated. The first housing part 7 is designed as a lower part, for example. The second housing part 8 is designed, for example, as a cover. The housing parts 7, 8 are preferably designed to correspond to one another. As for example in 2 shown, the housing element 5 in the exemplary embodiment is elongate, for example bone-shaped or bone-like.

The detection device 2 has at least three, for example four, in the receiving space 6, in particular acoustic, sensor elements 9-12, by means of which at least one acoustic signal 13 from an environment 14 of the motor vehicle 1 can be detected or is detected. The respective sensor element 9-12 is designed, for example, as a respective microphone. In this case, the respective microphone is preferably designed as a respective digital microphone. As a result, interference, in particular with respect to a respective analog microphone, can be kept particularly low.

The acoustic signal 13 is emitted, for example, by a noise source 15 which is located in the area 14 surrounding the motor vehicle 1 . The noise source 15 is a person, for example.

The detection device 2 is arranged on an outside 16 of a shell 17 of the motor vehicle 1 . In this case, the detection device 2, in particular via the housing element 5, can be held at least indirectly or directly on the component 4 and/or on the shell 17.

In order to be able to detect the acoustic signal 13 particularly well by means of the respective sensor element 9-12, provision is made for the sensor elements 9-12 to be arranged in pairs, in particular directly, adjacent and in pairs spaced apart from one another in a direction of extent 18 of the detection device 2 have different respective distances 19 from one another running in the direction of extension 18 . For example, a first of the sensor elements 9 is arranged along the extension direction 18 next to a second of the sensor elements 10 . For example, a third of the sensor elements 11 is arranged along the extension direction 18 next to the second sensor element 10 . For example, the fourth of the sensor elements 12 is arranged along the extension direction 18 next to the third sensor element 11 . For example, the second sensor element 10 is arranged between the first sensor element 9 and the third sensor element 11 in the extension direction 18 . For example, the third sensor element 11 is arranged between the second sensor element 10 and the fourth sensor element 12 in the extension direction 18 . Preferably none of the sensor elements 9-12 is arranged between the first and the second sensor element 9, 10, in particular along the direction of extent 18. Preferably none of the sensor elements 9-12 is arranged between the second and the third sensor element 10, 11, in particular along the direction of extent 18. None of the sensor elements 9-12 is arranged between the third and the fourth sensor element 11, 12, in particular along the direction of extent 18. The first and the second sensor element 9, 10 are spaced apart from one another by a first distance 19 in the direction of extent 18. The second and the third sensor element 10 , 11 are spaced apart from one another in the direction of extension 18 by a second distance 20 , which is in particular different from the first distance 19 . The third and the fourth sensor element 11, 12 are spaced apart from one another in the direction of extension 18 by a third distance 21, which is in particular different from the first and/or the second distance 19, 20.

Provision is preferably made for the sensor elements 9-12 to be arranged in the direction of extension 18 on a straight line 22, in particular an imaginary one. Provision is preferably made for the sensor elements 9-12 to be arranged on a support element 23 which is formed separately from the housing element 5, in particular is common, and which is formed, for example, as a circuit board. For example, the respective sensor element 9 - 12 is mechanically and/or electrically connected to the carrier element 23 .

In a further embodiment, it is provided that the respective sensor element 9-12 has at least one opening 25 provided for sound entry into a respective interior space 24 of the respective sensor element 9-12. The respective opening 25 is preferably covered by a respective membrane 26, in particular in a liquid-tight manner.

For example, the component 4 has at least three, for example four, through-openings 27-30, which are each associated with a respective one of the sensor elements 9-12, in particular the respective opening 25 or membrane 26. A first of the through openings 27 is assigned to the first sensor element 9 . A second of the through openings 28 is assigned to the second sensor element 10 . A third of the through openings 29 is assigned to the third sensor element 11 . The fourth of the through openings 30 is assigned to the fourth sensor element 12 . The respective sensor element 9-12 assigned to the respective through-opening 27-30, in particular the respective opening 25 or the respective membrane 26, is or can be connected to the environment 14 in a sound-transmitting and/or sound-permeable manner via the respective through-opening 27-30. Thus, the respective passage opening 27-30 is provided for sound entry, in particular the acoustic signal 13, into the respective interior space of the respective sensor element 9-12.

For example, the respective through-opening 27-30 is unevenly or irregularly shaped, in particular in its axial direction, for example in the radial direction and/or in the circumferential direction. Thus, the respective through-opening 27-30 can have non-uniform radii, for example, in particular along its axial direction. This means that the respective passage opening can be shaped like a trumpet, for example. As a result, the acoustic signal 13 can be detected or received particularly well by means of the respective sensor element 9-12.

For example, the component 4 is formed from a first part 32 on an outer side 31 . For example, a second part 33 of the component 4 that differs from the first part 32 adjoins the first part 32 on the inside, in particular at least indirectly or directly. For example, the first part 32 is formed from a first material and the second part 33 is formed, for example, from a second material that is different from the first material, the second material preferably being harder than the first material. Thus, the first material can be a soft material and the second material can be a hard or harder material. At for example, the second material is a plastic. For example, the first material is a thermoplastic elastomer (TPE). In the area of the respective through-opening 27-30, the first part 32 can be pulled through to the connection to the housing element 5, as a result of which an interface between the first part 32 and the housing element 5 can be optimally designed or mapped. In this way, disturbing noises and/or acoustic leaks can be avoided.

For example, the detection device 2, in particular the housing element 5, is at least predominantly covered on the outside by the component 4, in particular the first and/or the second part 32, 33. Thus, from the environment 14, for example, in particular in secondary surface areas, only the through-openings 27-30 are visible, which are preferably particularly small.

In a further embodiment, it is provided that the component 4 is formed separately from the shell 17 . The component 4 is thus designed, for example, as an add-on part. For example, the detection device 2 is held, in particular via the housing element 5, at least indirectly, in particular directly, via the component 4 on the shell 17.

in the in 3 until 5 shown embodiment, the component 4 is designed as a wing element 34. The wing element 34 is designed, for example, as a tailgate. In particular, the component 4 can be designed as a tailgate part of the tailgate. Provision is preferably made for the detection device 2 to be arranged in the region of a lower end 36 of the wing element 34, in particular the tailgate or the tailgate part, in relation to a vehicle vertical direction 35 of the motor vehicle 1. The lower end 36 is designed, for example, as the lower flap edge of the tailgate. For example, the component 4 is designed as a grip strip, which is preferably arranged in the area of the lower end 36, and in particular in the area of the lower end 36, in particular on the edge of the lid, is connected, in particular directly, to a base body of the tailgate or to the body is installed.

6 shows the arrangement 3 in a schematic perspective view according to a further embodiment. 7 12 shows the arrangement 3 according to the embodiment 6 in a schematic partial sectional view, in particular a cross section. 8th 12 shows the arrangement 3 according to the embodiment 6 in a schematic partial sectional view, in particular in a longitudinal section. in the in 6 until 8th shown respective embodiment, the component 4 is designed as an air guiding element 37, in particular as a spoiler, preferably as a rear spoiler. The air guiding element 37 is arranged, for example, on the wing element 34, in particular on the tailgate. Alternatively, the component 4 can be designed, for example, as an exterior mirror 38, in particular as a mirror base of the exterior mirror, or as a sill 39 or as a cover element 40, for example as a window strip. The spoiler can be understood in particular as a spoiler system.

The main body of the tailgate is designed, for example, in particular as a tailgate panel 41, which in 8th is shown. A pane 42 of the tailgate, referred to in particular as the rear window, is connected, in particular directly, to the tailgate panel 41 by means of adhesive 43, for example.

As for example in 3 and in 6 shown, it is provided in a further embodiment that the detection device 2 is arranged in a receiving area 44, in particular in the component 4. The receiving area 44 is designed, for example, as a wet area of the component 4 or of the motor vehicle 1 . The receiving area 44 is delimited at least partially, in particular completely, by a wall 45 embodied separately from the detection device 2 , in particular of the component 4 .

For example, a second receiving area 44a that differs from the receiving area 44 , in particular is spaced apart from the receiving area 44 , is separated from the first receiving area 44 by the wall 45 . The second receiving area 44a is designed, for example, as a dry area of the component 4 or of the motor vehicle 1 .

The sensor elements 9-12 are preferably connected, in particular at least indirectly or directly, to a connection device 46, in particular an electrical connection device, which extends at least in regions outside of the housing element 5. The connecting device 46 has, for example, a line element 47, in particular an electrical one, and a connection element 48, in particular an electrical one. The motor vehicle 1 has, for example, an in particular electrical and/or electronic component 49 which is embodied, for example, as an electronic computing device 50 . The connecting device 46 is provided for signal transmission, in particular for data transmission, between the sensor elements 9-12 and the component 49. the com component 49 is preferably arranged outside of the receiving area 44 . The component 49 is arranged in the second receiving area 44a, for example. The connecting device 46 can be part of the detection device 2 or can be formed separately from the detection device 2 .

in the in 2 The exemplary embodiment shown is provided with a sealing element 51 that covers the connecting device 46, in particular the connecting element 48, at least in some areas and is in contact with the housing element 5, in particular with the second housing part 8, and the wall 45, in particular directly, by means of which the housing element 5, in particular the second housing part 8, against the wall 45 can be sealed or is sealed. For example, the sealing element 51 is designed as a grommet.

Thus, the detection device 2 located in the receiving area 44, in particular in the wet area, can be connected, in particular electrically, via the connecting device 46 to the component 49, which is preferably located in the second receiving area 44a, in particular in the wet area, whereby the sealing element 51 can prevent the ingress of moisture into the housing element 5 and into the second receiving area 44a.

9 shows the detection device 2 in a schematic perspective view according to a further, in particular alternative, embodiment. In the, for example in 3 , 6 and 9 In the embodiment shown, a first sealing element 52 is provided that covers the connecting device 46, in particular the line element 47, and rests on the housing element 5, in particular on the second housing part 8, and the connecting device 46, in particular on the line element 47, in particular directly, by means of which the Housing element 5, in particular the second housing part 8, can be sealed or sealed against the connecting device 46, in particular the line element 47. The first sealing element 52 is designed as a grommet, for example.

In addition, there is a second sealing element 53 that covers the connecting device 46, in particular the line element 47, in some areas, butts against the wall 45 and the connecting device 46, in particular the line element 47, in particular directly, and is spaced apart from the first sealing element 52, by means of which the Connecting device 46, in particular the line element 47, can be sealed against the wall 45 or is sealed.

Thus, the detection device 2 located in the receiving area 44, in particular in the wet area, can be connected, in particular electrically, via the connecting device 46 to the component 49, which is preferably located in the second receiving area 44a, in particular in the wet area, whereby the first sealing element 52 can prevent moisture from entering the housing element 5 and the second sealing element 53 can prevent moisture from entering the second receiving area 44a.

For example, the connecting device 46 has a second, in particular electrical, connecting element 54 spaced apart from the first connecting element 48 . For example, the connection element 48 is arranged at one end on the line element 47 and the second connection element 54 is arranged, for example, on the line element 47 at the other end. For example, the line element 47 is connected or can be connected to the component 49 via the second connection element 54, in particular electrically.

Provision is preferably made for the wing element 34 to be held on the shell 17 so that it can pivot relative to the shell 17 between a closed position and at least one open position. In a further embodiment, at least one coupling device 55 is provided which can be coupled or is coupled to the wing element 34, by means of which the wing element 34 can be pivoted or is pivoted between the closed position and the open position depending on the acoustic signal 13 detected by the respective sensor element 9-12. For example, the wing element 34 can be pivoted electrically between the closed position and the open position by means of the coupling device 55 . Thus, the coupling device 55 can have, for example, at least one electrical machine for pivoting the wing element 34 .

For example, at least a first processing of the acoustic signal 13 detected by means of the respective sensor element 9-12, for example signal processing, can take place directly on the circuit board. Signal processing can thus take place on the circuit board. For example, the circuit board is in the form of an electronic computing device, in particular referred to as a second electronic computing device, or the circuit board includes the second electronic computing device.

For example, the signal 13 detected by means of the respective sensor element 9-12, which can be referred to in particular as a signal transmitter, can be processed, which can in particular be referred to as signal processing. The Signal processing takes place, for example, on the circuit board or in the microphone array. Subsequently, a signal transmission, in particular digital or analog, of the processed signal to the electronic computing device 50, in particular via the connecting device 46, can take place. The processed signal can thus be transmitted, preferably digitally, to the electronic computing device 50 . For example, the electronic computing device 50 includes a signal receiver. The signal transmitted to the electronic arithmetic unit 50 can be processed by means of the electronic arithmetic unit 50, in particular by means of speech recognition algorithms, which can in particular be referred to as signal processing.

Component 49, in particular electronic computing device 50, and/or the second electronic computing device is preferably configured to calculate a distance 56 between noise source 15, which emits acoustic signal 13, and to determine the motor vehicle 1. Alternatively or additionally, the component 49, in particular the electronic computing device 50, is designed to determine a direction 57 in which the noise source 15 is located in relation to the motor vehicle 1.

For example, the detection device 2 is aligned horizontally in its installation position in the motor vehicle 1, in particular at least essentially. As a result, the direction 57 can be determined particularly advantageously, in particular particularly precisely. In particular, interference sources and signal sources can be calculated out from one another, for example digitally. It is thus possible, for example, to determine particularly advantageously, in particular particularly precisely, in which direction 57 the person is located or from which direction 57 the person is approaching motor vehicle 1 .
