Technical Field

The invention relates to a sensor device for detecting at least one measured value for characterizing a state of an interior of a vehicle, in particular for detecting a temperature of the interior of the vehicle, wherein the sensor device has a wall element with an interior side provided with a closed surface, and has a rear side facing away from the interior side, and at least one first sensor assembly with at least one radiation sensor for detecting solar radiation, wherein the sensor device is designed to functionally face the interior side of the wall element towards the interior of the vehicle and to mount the rear side of the wall element in the vehicle facing away from the interior, wherein the wall element at least partially allows at least a portion of the solar radiation (measurable by means of the radiation sensor) to penetrate at least in a region with the closed surface of the interior side, and wherein the first sensor assembly is arranged on the back side of the wall element in the region of the closing surface on the side of the interior space.

The invention further relates to a method for producing such a sensor device and to a vehicle having such a sensor device.

Background

Sensor devices of this type are used, for example, in air conditioning systems of vehicles, which set the interior temperature on the basis of detecting the interior temperature.

In this connection, instead of a ventilation-type sensor device in which the temperature of the air flow in the fluid channel is detected, wherein the air flow is formed by means of a ventilation motor, a non-ventilation-type sensor device having a simple temperature sensor, which is coupled to the interior space in a manner suitable for temperature detection, is used in recent times.

Various non-ventilated sensor devices for this purpose are known from the prior art. On the one hand, sensor devices with temperature sensors are known, for example from the documents DE 102012219962B 3 or US 7,246,656B 2, which are designed for arrangement in openings in wall elements in order to be able to achieve the coupling to the interior space required for temperature detection of the interior space.

Furthermore, sensor devices are known, for example, from DE 102010015657 a1 or EP 2199125, which also have radiation sensors for additional detection of solar radiation, the latter documents giving the teaching: the radiation sensor and the temperature sensor may also be arranged behind the closing surface of the wall element.

Disclosure of Invention

Against this background, the object of the invention is to provide a different sensor device having a wall element with a closed surface, in particular an improved sensor device of this type, which preferably enables better detection of at least one measured value for characterizing the state of the vehicle interior, in particular more accurately.

The invention also provides a corresponding method for producing such a sensor device and a vehicle having such a sensor device.

According to the invention, the object is achieved by a sensor device having the features according to the respective independent claims, a method for producing such a sensor device and by a vehicle. Preferred embodiments of the invention are the subject of the dependent claims, the description and the drawings and are set forth in detail below.

A sensor device according to the invention is provided for detecting at least one measured value for characterizing a state of an interior of a vehicle, in particular for detecting a temperature of the interior of the vehicle, having a wall element with an interior side and a rear side facing away from the interior side, the interior side having an area with a closed surface; and the sensor device has at least one first sensor assembly with at least one radiation sensor for detecting solar radiation (or sunlight, incident light). The sensor device is designed to be functionally mounted in the vehicle with the interior side of the wall element facing the vehicle interior and with the rear side of the wall element facing away from the interior. The wall element at least in the region of the closed surface on the interior space side at least partially allows a portion of the solar radiation detectable by means of the radiation sensor, in particular the solar radiation in the infrared range, to penetrate.

According to the invention, the first sensor arrangement is integrated in the wall element from the rear side in the region of the closing surface on the interior space side, in particular integrated in such a way that the first sensor arrangement is surrounded by the wall element almost completely, particularly preferably completely.

That is, the first sensor arrangement is preferably substantially completely surrounded by the wall element. Preferably, however, cables or lines or the like can also be led out of the wall element, which cables or lines or the like are connected to the sensor assembly and are designed in particular for making electrical contact with one or more other components or components. I.e. the cable or wire etc. does not have to be completely surrounded by the wall element.

As a result, a particularly good optical and thermal coupling between the wall element and the first sensor arrangement can be achieved, and an advantageous, in particular improved, coupling of the first sensor arrangement to the interior space can then be achieved primarily by the wall element. Hereby, a better detection of at least solar radiation incident into the interior space of the vehicle and also of the interior space temperature in the additional presence of a temperature sensor can be achieved with the sensor device according to the invention.

The term "sensor assembly" is to be understood within the scope of the present invention to mean, in particular, an assembly having at least one sensor, preferably an assembly consisting of one or more sensors, wherein, in particular, the cables, lines, etc., which are required for electrical contact with one or more components or components, are not to be regarded as part of the sensor assembly. That is, the cable or line connected to the sensor assembly can be led out of the wall element in which the sensor assembly is integrated in order to connect the sensor assembly. It is not necessary on the contrary that the cables or lines etc. are also integrated in the wall element in particular completely.

The term "wall element" is to be understood within the scope of the present invention to mean, in particular, a wall or a wall section of a component which is designed as a functional structure adjacent to an interior space, for example, a wall of a panel or a wall section of a housing, for example, a wall section of a dashboard or center console. The wall element can also be formed by a wall or a wall section of the actuating element, for example a switch, for example by the bottom of a knob of cup-shaped design facing the interior.

The term "closed surface" is to be understood within the scope of the present invention in particular as an area of the surface which is free of openings, in particular perforations, slits or the like.

In this case, the wall element of the sensor device according to the invention can be designed in one piece, i.e. in particular the closing surface and the rear part of the wall element, in particular the entity forming the rear part of the wall element, can be part of the same integrally produced component. Alternatively, the wall element can also consist of a plurality of components, for example of one or more wall element bodies which form the rear part of the wall element and one or more components which have a closed surface or at least partially or completely form a closed surface, for example flaps or the like.

In other words, the closing surface and the rear part, in particular the rear side, of the wall element can be formed by one and the same component, i.e. an integrated component, or can also be formed by at least two different components.

The closing surface can be at least partially or completely part of a separate component or can be formed by a separate component which is arranged from the interior space side on a component, in particular a wall element body, which forms the rear side, for example a baffle which is fastened to the wall element body which forms the rear side, wherein the baffle can in particular form a wall element together with the wall element body.

In one possible embodiment of the sensor device according to the invention, the closing surface can also be formed at least partially or completely by a coating or the like, which accordingly is transparent to solar radiation. The wall element can in particular have a one-piece or multi-piece rear wall element body, on which a coating is applied, which coating forms or in this way forms the closing surface.

The closure surface can also be formed at least partially or completely by a coating on a separate component, for example by a coating on a flap.

The rear side of the wall element is preferably formed by a light-transmitting wall section, in particular by a respective radiation-transparent and/or light-transmitting wall element body, which can be designed in one piece or in multiple pieces, so that at least a part of the solar radiation, in particular the IR radiation contained in the solar radiation, impinging on the wall element can penetrate through the wall element and reach the first sensor arrangement, in particular the radiation sensor.

For this purpose, the wall element, in particular the rear area of the wall element located behind the closing surface, can have PMMA (polymethyl methacrylate) or be made of PMMA. However, a corresponding penetrable wall element is also conceivable, which has or is made of PC (polycarbonate) or PA12 (polyamide 12), for example.

In a preferred embodiment of the sensor device according to the invention, the wall element is permeable, in particular at least to the Infrared (IR) component contained in the solar radiation, preferably at least partially, in particular at least partially or regionally, i.e. in a specific region.

Infrared radiation is understood within the scope of the invention to be spectral in the range of 10^-3m and 7.8X 10^-7Radiation between m, i.e. in the wavelength range between 1mm and 780nm, which corresponds to 3X 10¹¹Hz to about 4X 10¹¹Frequency range between Hz (300GHz to 400 THz).

In A particularly preferred embodiment of the sensor device according to the invention, the wall element is permeable in particular to infrared radiation in the spectral range IR- A (0.78 to 1.4 μm), IR-B (1.4 to 3.0 μm) and/or IR-C infrared radiation (3 to 1000 μm), respectively, in particular to MIR radiation, i.e. IR-C radiation with A wavelength of 3 to 50 μm, preferably at least partially, in particular at least partially or regionally, i.e. in A specific region.

In A preferred embodiment of the sensor device according to the invention, the closing surface of the wall element and/or the wall element body are/is permeable, preferably at least partially, in particular at least partially or regionally, i.e. in A specific region, in particular to infrared radiation in the spectral range IR- A (0.78 to 1.4 μm), IR-B (1.4 to 3.0 μm) and/or IR-C infrared radiation (3 to 1000 μm), in particular to MIR radiation, i.e. IR-C infrared radiation with A wavelength of 3 to 50 μm, respectively, in particular to Infrared (IR) radiation contained in the solar radiation.

In one possible embodiment of the sensor device according to the invention, the closing surface of the wall element is an operating surface and/or a design surface of the operating element, i.e. a surface which is specially designed for design reasons, or respectively a region therein.

Alternatively, the closing surface may also be a simple surface only, i.e. not necessarily a functional surface. The closing surface can in particular be only the closing surface facing the interior space, which can be acted upon by solar radiation, in particular such that the solar radiation can pass through this surface to a first sensor arrangement with a radiation sensor, which is arranged on the side of the wall element facing away from the interior space, in order to be able to be detected by a first sensor device, in particular by the radiation sensor.

The closed surface and the rear portion of the wall element are preferably designed to be as thermally conductive as possible in order to achieve good thermal coupling and thus good heat transfer from the interior space to the first sensor arrangement.

In this case, the closing surface is particularly preferably in material-to-material contact with the rear face section of the wall element and is correspondingly connected in a radiation-permeable manner, in particular with the respective wall element body, so that a good heat transfer through the wall element to the first sensor arrangement is achieved.

The term "materially bonded connection" is intended to be understood within the scope of mechanical convention and within the scope of the invention in particular as a connection which is not detachable except for damage, wherein the bonded fittings are bonded at least in part by atomic and/or intermolecular forces, for example by welding, soldering or adhesive bonding.

In a further possible embodiment of the sensor device according to the invention, the first sensor component is connected to the wall element, preferably over its entire outer surface, in a materially bonded manner. As a result, a particularly good optical and thermal coupling between the wall element and the first sensor arrangement can be achieved, and thus an advantageous, in particular improved, coupling of the first sensor arrangement to the interior space (via the wall element) can be achieved.

In a further particularly advantageous embodiment of the sensor device according to the invention, the first sensor arrangement is integrated in the wall element by means of an injection-molded coating (Umspritzen) of a wall element mass which is at least partially permeable to at least a part of the solar radiation which can be measured by means of the radiation sensor, in particular such that the first sensor arrangement is substantially completely surrounded by the wall element, preferably by a wall element body, in particular a wall element body consisting of the wall element mass, wherein the first sensor arrangement is particularly preferably connected to the wall element in a material-bonded manner. The first sensor component can be integrated particularly easily in the wall element body or in the wall element by injection molding of the first sensor component.

In a further possible, particularly alternative, in some cases advantageous embodiment of the sensor device according to the invention, the wall element has at least in part a wall element body which is permeable to at least a part of the solar radiation which can be measured by means of the radiation sensor, wherein the first sensor component is connected to the wall element body by injection molding and/or adhesive bonding and/or bonding, particularly by optical bonding and/or thermal bonding, optionally with a connecting compound which is also permeable at least in part to at least a part of the solar radiation which can be measured by means of the radiation sensor, wherein the wall element body surrounds the first sensor component together with the connecting compound, so that the first sensor component is integrated in the wall element. The integration of the first sensor in the wall element can thereby also be realized particularly simply. Furthermore, a particularly good optical path from the wall element to the first sensor arrangement can be achieved by means of optical bonding and/or thermal bonding.

This can be achieved particularly simply if the wall element has a recess, preferably a recess with a bottom and an inner circumferential wall for accommodating the first sensor arrangement, wherein the first sensor arrangement is arranged at least partially inside the recess and is connected in a material-bonded manner to the wall element body by means of a connecting mass, wherein in those regions in which the first sensor arrangement is not enclosed by the wall element, the first sensor arrangement is preferably enclosed by the connecting mass, so that in particular the wall element together with the connecting mass is enclosed by the first sensor arrangement, and the first sensor arrangement is integrated in the wall element and is almost completely enclosed by the wall element.

The term "optical bonding" (or optical bonding, optical bonding) is to be understood within the scope of the present invention as meaning a connection, for example an adhesive, which produces a material bond and is constructed such that undesired optical interference effects, for example cloudiness, blurring, distortion, reflections, etc., caused by conventional adhesion in the optical path, are reduced or completely avoided. In other words, an "optically true/distortion-free" connection (material-bonded) is established by optical bonding. "optical bonding" is per se substantially known in the prior art.

The term "thermal bonding" (or thermal bonding, thermal bonding) is to be understood within the scope of the present invention as the creation of a connection, the result of which is a good heat transfer and which is in particular designed to achieve a direct, in particular planar, heat transfer between the joining partners. The connection fittings are preferably connected to one another in a material-bonded manner, wherein the connection fittings can be connected to one another in a material-bonded manner both directly and by means of a connecting material. A particularly advantageous connection is formed if the components to be joined are first surface-structured in a defined manner and method and are subsequently joined under the influence of pressure and heat. In particular, an "optically true/distortion-free" connection can be established in this way, which moreover also achieves good heat transfer. "thermal bonding" is likewise known per se in the prior art.

Preferably, the first sensor arrangement is connected in a bonded manner to the wall element in each case, so that no air gap is present between the first sensor arrangement and the surrounding wall element region, in particular between the surrounding wall element body. A particularly good heat transfer from the wall element to the first sensor assembly can thereby be achieved, since an isolating air gap between the wall element and the first sensor assembly can be avoided. Hereby, both a better heat transfer of the thermal radiation caused by the incident solar radiation and a better heat transfer from the wall element to the first sensor assembly may be achieved.

In some cases, it may also be advantageous to design the sensor device in such a way that the first sensor arrangement is arranged on the rear side of the wall element in the region of the closing surface on the interior space side, wherein the wall element has a depression for this purpose with a bottom and an interior circumferential wall for accommodating the first sensor arrangement, in particular on the rear side of the wall element, and the first sensor arrangement is arranged at least partially in this depression in the wall element, wherein the first sensor arrangement is connected in a bonded manner with the bottom and the interior circumferential wall material of the depression of the wall element, wherein the first sensor arrangement is only partially surrounded by the wall element. In this case, the first sensor arrangement is therefore not integrated in the wall element, but is connected to the wall element body, preferably to the base and the inner circumferential wall, by a materially bonded connection. In many cases, therefore, a sufficient optical and thermal coupling between the wall element and the first sensor arrangement and in particular a sufficient coupling of the first sensor arrangement to the interior space can already be provided, wherein this design is not part of the present concept, but rather a further concept is provided which can be implemented in combination with the design described below, i.e. a modular design can be formed, as long as it is technically possible.

In an advantageous embodiment of the sensor device according to the invention, the recess is designed in particular for accommodating the first sensor component at least in sections if the wall element has a corresponding recess, wherein the recess is in particular a hollow, preferably a shell-like, prism-like, cup-like or cylindrical hollow, for example a blind hole with a circular cross section.

The circular cross section of the recess extends parallel to the interior space side of the wall element, in particular to the closing surface. However, this is not mandatory. The opening cross section of the recess for accommodating the first sensor component can also extend obliquely with respect to the interior space side, in particular the closing surface. The longitudinal axis of the recess, in particular of the pyramid, cup or cylinder-shaped recess, can likewise be oriented perpendicular to the interior space side of the wall element, in particular the closing surface, or extend obliquely thereto.

The first sensor arrangement can be arranged with its longitudinal axis oriented perpendicularly to the closing surface or with its longitudinal axis inclined relative to the closing surface.

The recess can in principle also have a cross section of any shape, but it should preferably be adapted to the circumferential contour of the first sensor component to be accommodated, so that the first sensor component can be placed in the recess with a small gap and a material-bonded connection between the first sensor component and the wall element can be produced with as little effort as possible.

Preferably, the gap size is selected in such a way that, in the state before the material-bonded connection is established, a process-reliable, material-bonded connection can be established, in particular a process-reliable, so that it is ensured that air inflow, which would adversely affect the heat transfer due to the insulating effect of the air, is avoided.

In an advantageous embodiment of the sensor device according to the invention, the first sensor component is connected to the wall element, preferably in a material-to-material manner, by means of a connecting material which is also at least partially permeable to at least a part of the solar radiation which can be measured by means of the radiation sensor, in particular by means of a corresponding permeable, thermally conductive connecting material, for example by means of a corresponding permeable, thermally conductive silicone material.

In an advantageous embodiment of the sensor device according to the invention, the sensor arrangement is connected in a materially bonded manner to the wall element, in particular by injection molding, bonding and/or bonding, in particular by optical bonding and/or thermal bonding, in particular such that the first sensor arrangement is finally integrated in the wall element. This enables advantageous radiation transmission and/or good heat transfer.

In a further advantageous embodiment of the sensor device according to the invention, the wall element is preferably designed to influence the optical path of the incident solar radiation, in particular the optical path inside the wall element, in a defined manner, wherein the wall element is designed in particular to deflect the incident solar radiation, preferably in the direction of the radiation sensor, and/or the wall element is designed to reduce or prevent the penetration of the solar radiation into the rear sensor chamber.

If the wall element is composed of a plurality of components, in particular of a respective wall element body and/or a respective wall section comprising a depression and a part comprising a closed surface, in particular a component of the wall element comprising the rear side of the wall element or a component comprising a depression is configured for deflecting the optical path of the incident solar radiation.

In an advantageous embodiment of the sensor device according to the invention, in particular in an advantageous development, the wall element has, in particular, at least one reflection surface for influencing, in particular for deflecting, the optical path of the incident solar radiation, on which the incident solar radiation can be at least partially reflected.

The reflection surface is preferably formed in particular by an at least partially or completely planar surface; the reflecting surface may alternatively or locally be curved, for example a concavely curved surface. In some cases, it is thus possible not only to influence, in particular deflect, the incident solar radiation, but also to concentrate (in particular alternatively or additionally) the incident solar radiation in a corresponding manner of design. This may be advantageous in some situations.

In other cases, scattering is advantageous, wherein the reflection surface can be concave curved or have concave curved sections.

The optionally present reflection surfaces are preferably each designed in particular to achieve a favorable effect on the incident solar radiation.

In an advantageous embodiment, in particular in a further development, of the sensor device according to the invention, the reflective surface is formed at least partially, preferably completely, by a reflective layer applied to the wall element from the rear side.

In an advantageous embodiment of the sensor device according to the invention, the reflection surface extends at least partially obliquely with respect to the closing surface of the wall element, preferably obliquely at a defined angle with respect to the closing surface of the wall element.

For many applications, in particular in combination with a flat closing surface of the wall element, which extends perpendicularly to the longitudinal axis of the first sensor assembly, an (inner) angle of 45 ° is considered to be particularly advantageous. A 90 ° deflection of the solar radiation arriving perpendicularly at the closed surface can thereby be achieved in a simple manner.

For the desired influencing, in particular deflecting, of the incident solar radiation, a plurality of reflection surfaces or reflection surfaces extending around the first sensor arrangement, for example, reflection surfaces extending in a frustum-like manner around the radiation sensor, may also be present.

This is known in the prior art, for example, from the above-mentioned document DE 102010015657 a1, to which reference is made for a specific embodiment of the basic operation of a corresponding sensor device having a radiation sensor and a temperature sensor.

In order to detect the interior temperature as accurately as possible, in a preferred advantageous embodiment of the sensor device according to the invention, the wall element is preferably designed to be as thermally conductive as possible, in order to achieve good heat transfer with the first sensor arrangement.

In an advantageous embodiment of the sensor device according to the invention, the first sensor arrangement is arranged, in particular, at least partially in the recess, and preferably the radiation sensor and/or the first temperature sensor are arranged at least partially inside the recess. Good heat or radiation transfer at the individual sensors can thereby be ensured.

In an advantageous development of the sensor device according to the invention, the radiation sensor and the first temperature sensor of the first sensor arrangement are preferably arranged in a common housing, for example in a cup-shaped or thimble-shaped housing, wherein in this case preferably the outer wall of the housing is connected at least partially in a materially bonded manner to the wall element.

By arranging the radiation sensor directly in the vicinity of the first temperature sensor, i.e. together with the radiation sensor, inside the first sensor assembly, the influence of the incident solar radiation on the first temperature sensor can be detected with high accuracy, which enables good compensation and thus better detection of the interior space temperature.

In order to detect the interior temperature more precisely, the sensor device constructed according to the invention can also have a second sensor arrangement with at least one second temperature sensor, wherein the second temperature sensor is preferably arranged outside the wall element.

The use of a second temperature sensor for correcting and/or at least partially compensating the measured interior temperature is also known in the prior art, for example, also from DE 102010015657 a1, to which reference should be made in detail.

Preferably, the second sensor arrangement, in particular the second temperature sensor, is arranged here from the rear on the wall element, in particular in the sensor chamber of the rear.

Preferably, the second temperature sensor is designed to detect a temperature in particular in the surroundings of the rear side of the wall element, in particular in the sensor chamber of the rear side.

In a particularly advantageous embodiment of the sensor device according to the invention, the first sensor arrangement is designed such that the information provided by the radiation sensor is used to correct the temperature of the interior space measured by the temperature sensor, wherein the temperature sensor and the radiation sensor can be arranged in a common housing and are in electrical contact with a printed circuit, in particular a carrier plate or a circuit board, of the carrier plate via contact elements, wherein the further contact elements are electrically connected to at least one control device, which has an evaluation and control circuit.

In some cases, it is advantageous for the circuit board, the printed circuit board, and/or the printed circuit board to be arranged or to extend on at least one surface of the carrier plate in a meandering and/or meandering manner.

With the aid of the second temperature sensor, information can be used to correct the interior temperature measured by the first temperature sensor, which information relates in particular to: in this way, a further improved correction, in particular a further improved temperature compensation, of the measured temperature of the interior can be achieved, for example, by virtue of the fact that the ambient temperature is present in the immediate vicinity of the electrical component connected to the first temperature sensor and/or the radiation sensor, for example, in the immediate vicinity of the carrier plate.

In a particularly advantageous embodiment of the sensor device according to the invention, the second temperature sensor is arranged in particular also on the carrier plate, in particular on the second carrier plate, preferably on the second circuit board, and in particular preferably also in electrical contact with the printed circuit, wherein the printed circuit is preferably arranged or extends in a meandering and/or meandering manner on at least one surface of the second carrier plate.

Preferably, the radiation sensor has one or more photodiodes. The radiation sensor may however also be a different radiation sensor designed for detecting solar radiation, such as a photoresistor, a phototransistor or in general an optical semiconductor. It is also possible to envisage the use of a double thermocouple, in particular a so-called double NTC, as described in document DE 102018132103.1.

At least one of the two temperature sensors is preferably an NTC, so-called "thermistor" or "negative temperature coefficient thermistor", as it is generally known and is widely known in the art. NTCs are particularly well suited as sensing devices for detecting ambient temperature, which may be the basis for temperature compensation. Furthermore, the NTC can be implemented very inexpensively and is particularly small and compact and thus saves installation space, as a result of which the installation space requirement for the sensor assembly and thus for the entire sensor system can be kept small.

However, one or both temperature sensors may also be simple thermocouples, which however usually achieve a less accurate temperature detection.

In an advantageous embodiment of the sensor device according to the invention, the first sensor assembly and/or the second sensor assembly can be electrically connected or connected to the control device by means of a flat cable or at least one flexible cable, in particular can be electrically contacted or contacted by one or more correspondingly configured contact elements.

In this way, the temperature influence on the electrical component due to the heating of the sensor cavity around the electrical component, in particular due to the heating caused by solar radiation penetrating into the sensor cavity, can be reduced.

In an advantageous embodiment of the sensor device according to the invention, the shielding means has a reflective layer which is designed to at least partially reflect incident solar radiation and/or to at least partially reduce the incidence of solar radiation on the rear sensor chamber. This reduces the heating of the sensor chamber and thus enables the accuracy of the detection of the temperature in the interior, since the heating of the electrical component influences the properties of the electrical component.

In a particularly advantageous embodiment of the sensor device according to the invention, the reflective layer of the shielding means is at least partially, in particular, a reflective layer applied to the rear side of the wall element, in particular a reflective coating applied to the rear side of the wall element. Shielding can thereby be achieved in a particularly simple manner.

By means of the encapsulation, in particular by means of the additionally present air layer between them, the heating of the encapsulated electrical component can be reduced, which is advantageous for the accuracy of the detection of the temperature of the interior space.

In an advantageous embodiment of the sensor device according to the invention, the shielding means has a shielding hood which shields the one or more electrical elements arranged in the sensor chamber and/or the second temperature sensor, in particular with respect to incident solar radiation.

The shielding can is formed, for example, at least partially or completely by a wall section of the sensor device housing projecting from the encapsulation housing and/or a wall section projecting inward into the sensor chamber.

Detailed Description

Fig. 1 shows a schematic configuration of a first embodiment of a sensor device 10 according to the invention in a sectional view, wherein the sensor device 10 is configured for detecting the interior temperature of a vehicle. The sensor device 10 has a wall element 12 having an area with an interior space side with a closing surface configured as a design surface 11; and the sensor device has a rear side R facing away from the interior space side, which is formed by a wall element body 13 which can be penetrated by radiation (MIR radiation) with a wavelength of 3 to 50 μm, in particular originating from the sun, for example made of PMMA, wherein the design surface 11 can likewise be penetrated by this radiation.

The sensor device 10 also has at least one first sensor assembly 15, which is provided with at least one radiation sensor 23 for detecting solar radiation S and a first temperature sensor 24 for detecting the temperature in the interior I of the vehicle. The radiation sensor 23 and the first temperature sensor 23 are arranged in a common housing.

The sensor device 10 is designed to be installed in a vehicle with the interior side of the wall element 12 facing the vehicle interior I and with the rear side R of the wall element 12 facing away from the interior in terms of function.

In this case, the first sensor arrangement 15, in particular the housing in which the radiation sensor 23 and the first temperature sensor 24 are arranged, is arranged on the rear side R of the wall element 12, wherein the wall element 12 has a recess 25 with a bottom and an inner circumferential surface for accommodating the first sensor arrangement 15, and wherein the first sensor arrangement 15 is arranged at least partially within the recess 25 of the wall element 12, in particular in the wall element body 13.

According to the invention, the first sensor arrangement 15 with the radiation sensor 23 and the first temperature sensor 24 is integrated in the wall element 12, in particular the wall element body 13, wherein the first sensor arrangement 15 is mounted in the recess 25 and is surrounded, in particular injection-molded, by the connecting compound 19, so that the first sensor arrangement is almost completely surrounded, except for the line 16, by the wall element 12, in particular the wall element body 13, and the connecting compound 19.

As an alternative, the first sensor arrangement 15 can also be connected to the wall element body 13 in a bonded manner by thermal and optical bonding and can thus be integrated in the wall element body.

The first sensor arrangement 15, in particular its housing, is connected in a bonded manner by means of a connecting compound 19, primarily to the bottom 23 of the recess 25 of the wall element body 13 and to the inner circumferential wall material, wherein the connecting compound 19 is a silicone connecting compound 19 which is likewise transparent at least to IR radiation in the wavelength range of 3 to 50 μm.

This makes it possible to achieve an advantageous optical and thermal coupling between the wall element 12, in particular the wall element body 13, and the first sensor arrangement 15 (in this case in particular the housing of the first sensor arrangement 15), and thus a good heat transfer of the incident solar radiation S and a heat transfer at a temperature T, not specifically identified here, in the adjacent vehicle interior I.

The first sensor arrangement 15 is in this case electrically connected or in electrical contact with a circuit board 17 via a first contact element 16, wherein the circuit board 17 can be connected via a second contact element 18 to a corresponding control device, not shown here, for evaluating the measured sensor signals and for controlling, for example, a vehicle air conditioning system intended to regulate the temperature of the interior space.

Furthermore, this exemplary embodiment of the sensor device 10 according to the invention has a second temperature sensor 21, which is located behind the wall element 12 in a sensor chamber on the rear side, which is not shown in detail here, and which is likewise in electrical contact with the circuit board 20. The circuit board 20 can likewise be connected to a corresponding evaluation and/or control device via further contact elements 22.

In view of the thermally conductive properties of the surface 11 embodied as the closing surface 11 and of the wall element body 13, the temperature in the interior space I of the vehicle can be detected by means of the first temperature sensor 24 of the first sensor arrangement 15, which surface 11 and wall element body 13 together form the wall element 12, wherein both the silicone connecting compound 19 and the housing are designed to have particularly good thermal conductivity in order to be able to detect the interior space temperature particularly accurately by means of the first temperature sensor 24.

As a result, the incident solar radiation S can be detected by means of the radiation sensor 23 (which is therefore arranged in the immediate vicinity of the first temperature sensor 24) accommodated in the common housing of the first sensor arrangement 15, and the errors of the first temperature sensor 24 caused by the solar radiation, in particular the measurement errors caused by the solar radiation and the resulting heating, can be corrected, in particular compensated computationally, by means of the associated evaluation and/or control device. This is basically known in the art and therefore will not be described in further detail in this application.

In order to achieve a compensation which is as accurate as possible, a second temperature sensor 21 is provided which is arranged in the immediate vicinity of the electrical components of the first sensor arrangement 15, in particular in the immediate vicinity of the electrical components which participate in the temperature compensation process, for example ICs arranged on a circuit board.

The ambient temperature of the components in the rear sensor chamber can be detected by means of the second temperature sensor 21 and likewise compensated for by calculation. This is also known in the art and will therefore not be described in further detail in this application.

A second temperature sensor 24 is in electrical contact with the second circuit board, and can likewise be electrically connected to a corresponding evaluation and/or control device via a corresponding further contact element 22 connected to the second circuit board 20.

Fig. 2 shows an alternative second exemplary embodiment of a sensor system 10' according to the invention, in which a first sensor arrangement 15 is integrated in the wall element 12 by injection molding with a correspondingly radiation-permeable wall element mass 13, which forms the wall element body 13.

Fig. 3 shows a sectional view through the sensor device 10 in the section plane a-a in fig. 1 from the perspective of the interior space side, wherein in this view it is particularly clearly shown how the first sensor arrangement 15 or the common housing accommodating the radiation sensor 23 and the first temperature sensor 24 is connected by means of the silicone connecting compound 19 to the inner circumferential surface of the recess 25 of the wall element 12, in particular to the wall element body 13, in a bonded manner.

Fig. 4 shows a third exemplary embodiment of a sensor system 30 according to the invention, which differs from the sensor system 10 according to the invention shown in fig. 1 in that the sensor system 30 of the third exemplary embodiment does not have a second temperature sensor 21 and does not have an associated second printed circuit board 20 and corresponding further contact elements.

The other difference is that in this case the longitudinal axis a of the recess 25 (which coincides with the longitudinal axis of the first sensor assembly 15) is not perpendicular to the surface 11 on the interior space side of the wall element 12, but extends at an oblique angle thereto. The view of fig. 4 is understood here only as an exemplary illustration. A plurality of different designs and arrangements, in particular of the first sensor arrangement 15 relative to the interior space side surface 11 and of the wall element 12, in particular of the wall element body 13, can also be realized within the scope of the invention.

The wall element 12, in particular the wall element body 13, is preferably designed here such that the incident solar radiation S is deflected in an advantageous manner in the direction of the radiation sensor 23, which can be achieved in particular by means of a corresponding bevel 14 on the rear side R of the wall element body 13, as described in this embodiment and in the previous embodiment with reference to fig. 1.

Fig. 5 shows a fourth exemplary embodiment of a sensor device 40 according to the invention, which is constructed in principle analogously to the sensor device 10 shown in fig. 1, but likewise like the sensor device 30 shown in fig. 4, does not have a second temperature sensor 21 and likewise does not have a second circuit board 20 and corresponding further contact elements 22.

In addition to the sensor device 10 shown in fig. 1, the sensor device 40 according to fig. 5 also has a reflective layer 26 applied to the oblique surface 14 in each case in the form of a reflective coating, with which it is possible to prevent solar radiation S from passing through the oblique surface 14 into the rear sensor chamber, since it is reflected by the reflective layer 26.

Due to the arrangement of the reflective layer 26 and the design of the oblique surfaces 40, 14 at an angle of 45 ° relative to the surface 11 or in particular relative to the incident solar radiation S, the incident solar radiation S can be deflected in a targeted manner in a simple manner in the direction of the radiation sensor 23, in this case in particular up to a deflection of 90 ° in view of the angle of 45 °.

This makes it possible to achieve a favorable influence on the beam path of the incident solar radiation S and thus a high degree of accuracy in the detection of the solar radiation S by means of the radiation sensor 23.

Fig. 6 shows a fifth exemplary embodiment of a sensor device 50 according to the present invention, wherein, unlike the sensor device 10 according to fig. 1, in this sensor device 50 there is no corresponding inclined surface 14 in the wall element body 13 and correspondingly no reflective layer 26 for shielding the sensor cavity from the incident solar radiation S.

However, the sensor device 50 has an encapsulating housing 27 which at least partially encapsulates the circuit board 17 and the first and second contact elements 16, 18, in particular with an air layer on the inside, in order to protect the circuit board 17 and the electrical components located thereon from the heating caused by the temperature of the rear sensor chamber.

As a result, adverse effects on the electrical components arranged inside the encapsulating housing 27 due to heat can be reduced or even completely avoided, which is advantageous for the accuracy of the measurement of the temperature of the interior space.

Fig. 7 shows a sixth exemplary embodiment of a sensor device 60 according to the present invention, which, in addition to the enveloping housing 27, also has a shielding 28 formed by the wall section 28 of the enveloping housing 27, by means of which the second temperature sensor can be shielded from incident solar radiation.

In order to better shield the sensor chamber on the rear side from incident solar radiation S, a further shielding element 29 is provided, which is arranged directly around the temperature sensor 21 and directly shields it.

In order to produce the sensor device according to the invention, the first sensor component 15 is first of all prepared and in a subsequent step integrated into the wall element 12, preferably by injection molding with the wall element mass 13 or by a material-bonded connection by means of the connecting mass 19 to the wall element body 13, wherein the first sensor component 15 is already arranged for this purpose, in particular, in the recess 25. Subsequently, the sensor device is prepared in the next step.
