Sensor system for activating at least one vehicle function

Description

[0001] The present invention relates to a sensor system for activating at least one vehicle function of a vehicle according to the type defined in more detail in the preamble of claim 1. Furthermore, the invention relates to a sensor module according to the preamble of claim 8, a vehicle according to the preamble of claim 10, and a method for activating at least one vehicle function of a vehicle.

[0002] It is known from the prior art, e.g., from EP 0 582 969 A or DE 10 2006 012336 A1, that touch- and / or pressure-sensitive sensors as well as proximity sensors can be provided in vehicles. Such sensors can be used, for example, in a door handle to detect a touch. Most pressure sensors are accessible from the outside to ensure accurate measurement. In response to a detection by the corresponding sensor, a vehicle function can be activated, e.g., an electronic lock. Thus, simply touching the door handle can intuitively open the door. Capacitive sensors are frequently used for this purpose.

[0003] A disadvantage of existing solutions, particularly capacitive sensors, is that processing the sensor data is complex and technically demanding. In particular, environmental factors such as humidity or rain can complicate the evaluation. Furthermore, conventional sensor systems often limit the possibilities for activating vehicle functions. Touch- and / or pressure-sensitive sensors typically require an opening to penetrate the adjacent surface, making their measuring range directly accessible from the outside. This creates additional installation challenges, such as sealing against moisture, mechanically absorbing the necessary pressure forces on the sensor, and similar issues.

[0004] It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide an improved sensor system that offers a more reliable and / or convenient and / or simpler way of activating vehicle functions. In particular, the design and mechanical effort required when using the improved sensor system in the vehicle should be kept to a minimum.

[0005] The foregoing problem is solved by a sensor system with the features of claim 1, a sensor module with the features of claim 8, a vehicle with the features of claim 10, and a method with the features of the independent method claim. Further features and details of the invention will become apparent from the respective dependent claims, the description, and the drawings. Features and details described in connection with the sensor system according to the invention naturally also apply in connection with the sensor module, the vehicle, and the method according to the invention, and vice versa, so that the disclosure of the individual aspects of the invention always makes, or can make, reciprocal references.

[0006] The problem is solved in particular by a sensor system for activating at least one vehicle function of a vehicle, preferably for activating at least one electric lock of the vehicle, comprising at least: at least one first and second (and in particular third and possibly fourth or at least one further) sensor element each for detecting a deformation in at least one (or a respective) deformation area on the vehicle, at least one (in particular at least partially electronic) processing device for evaluating the respective detection of the sensor elements, in particular by receiving and / or processing respective detection signals of the sensor elements.

[0007] In other words, at least two or more, and in particular a plurality, of sensor elements can be provided, especially on the vehicle. For example, a first sensor element can be provided to perform a first detection of a first deformation in a (first) deformation zone on the vehicle. Furthermore, for example, a second sensor element can be provided to perform a second detection of a second deformation in the same deformation zone or in a second deformation zone on the vehicle, and / or a third sensor element can be provided to perform a third detection of a third deformation in the same deformation zone or in a third deformation zone on the vehicle, and / or a fourth sensor element can be provided to perform a fourth detection of a fourth deformation in the same deformation zone or in a fourth deformation zone on the vehicle. In particular, the same applies analogously to further (fifth, sixth, seventh, etc.) sensor elements.Thus, the invention makes it possible to arrange the sensor system, for example, on the inside of a vehicle sheet, plate or structural surface of the vehicle without any structural changes, which thus simultaneously forms the deformation area, and which can be operated by a user on the outside (opposite side of the surface to the sensor system).

[0008] The system is designed so that a deformation profile detected by at least some of the sensor elements can be evaluated by the processing device. Depending on the (detected) deformation profile and / or the evaluation by the processing device, at least one vehicle function can be activated. For example, the evaluation can detect a specific deformation profile that differs from other deformation profiles. Thus, for instance, a first vehicle function can be activated upon detection of a first deformation profile, and a second vehicle function upon detection of a second deformation profile. This offers the advantage of providing a very reliable and convenient method for activating the vehicle function.

[0009] Furthermore, it is possible for the deformation (especially as a single deformation) and / or a deformation profile to be detected by multiple sensor elements (e.g., simultaneously), with the respective detection signals from the sensor elements preferably being evaluated for the assessment and / or detection of the deformation and / or the deformation profile and / or a gesture. Safety can be increased if, for example, multiple sensor elements are used for detection. For this purpose, the detection signals can be compared with each other. It is also possible for at least some of the sensor elements to be aligned with a common deformation area in such a way that a deformation within that area is detected redundantly. Thus, the detection of one or more deformations by multiple sensor elements can preferably be carried out redundantly.

[0010] The deformation process can be triggered, for example, by a (mechanical) gesture from the vehicle's user, whereby the user deforms at least one vehicle part within the deformation zones in a specific way (e.g., with a specific sequence, speed, or the like) by applying a force. This force could be, for example, lightly touching or pressing the vehicle part with a finger. The sensor elements can be designed to be so sensitive that even the smallest deformations of the vehicle part within the deformation zone can be detected. This can drastically improve the reliability and / or usability of the detection, especially compared to capacitive sensors.

[0011] Preferably, a deformation profile is understood to be a (particularly temporal) progression and / or sequence of deformations (possibly also referred to below as activation or deformation movement or activation action or deformation sequence) in the deformation areas. Based on the deformation profile, deformations in different deformation areas can be distinguished. For example, the processing device evaluates and / or determines information about at least one of the following parameters: Intensity of the respective deformation, direction of the deformation sequence, speed of the deformation sequence, geometry of the deformation sequence.

[0012] This allows a wide variety of parameters to be used in the evaluation, enabling the detection of numerous different activation patterns. These activation patterns can be detected, for example, based on various specifications for the deformation process and / or the aforementioned parameters (where the specifications differ for each activation pattern). Thus, identical deformation sequences at different speeds can be detected as different activation patterns based on the sensor data. This allows for the activation of different vehicle functions depending on the detected activation patterns.

[0013] It is conceivable that the first deformation area differs at least partially from the second deformation area, and preferably the deformation areas can also overlap. Alternatively or additionally, at least some of the deformation areas can also be spaced apart, e.g., with a distance in the range of 1 to 10 cm, preferably 3 to 6 cm.

[0014] Furthermore, it is possible that, in addition to the sensor elements, at least one sensor unit is provided, and / or that the processing device evaluates the readings from this sensor unit. For example, the sensor unit may be configured differently from the sensor elements with regard to its sensor type, e.g., as a capacitive sensor. In particular, the readings from this sensor unit may be compared with the readings from the respective sensor elements, especially by the processing device. This allows, for example, the plausibility of the sensor element readings to be verified using threshold values ​​or similar methods.

[0015] It may be provided that at least a detection result is determined through the evaluation of the processing device, whereby further evaluations and / or processing may be carried out to determine the detection result. In particular, it is possible that the processing device provides the detection result and / or evaluation result as an electrical signal that indicates a specific deformation profile and / or an activation pattern. For example, the electrical signal could simply represent a binary "1" to indicate a positive detection of a specific deformation profile. This signal can then be evaluated, for example, by vehicle electronics, so that the vehicle function can be activated by the vehicle electronics depending on the signal.

[0016] According to the invention, the at least first and second sensor elements (i.e., possibly also the further sensor elements) are each designed for inductance measurement, such that a measurement result of the inductance measurement is specific for the deformation in the (respective) deformation area, in particular the deformation on an outer panel of the vehicle. The respective sensor elements can, for example, have an (inductive) coil element (or an inductive coil) to measure inductance and / or detect a change in inductance. This inductance or change in inductance can then be specific for the deformation. In this way, a deformation and / or a pressure exerted on a vehicle part in the deformation area (as an activation action) can be detected very reliably. For example, various activation actions (e.g.,a sequence of deformations in different deformation areas) together form an activation pattern, so that depending on a specific activation pattern, a vehicle function associated with it can be activated.

[0017] In particular, the deformation area can extend at least partially over (at least) one vehicle part. Preferably, this vehicle part is at least partially formed as part of the vehicle's exterior cladding and / or body, for example, also or only outside the vehicle's door handles. For example, at least one of the deformation areas extends in a region of a vehicle part below or adjacent to at least one of the vehicle's door handles. Alternatively, the vehicle can be designed without door handles, and / or the deformation areas can replace the door handles.

[0018] Preferably, the vehicle component can have a marking, particularly at least partially within or adjacent to the deformation area. For example, this marking can serve to indicate the deformation area as an activation zone for a user. Thus, the marking can be visibly located on the outside of the vehicle component. Alternatively or additionally, the marking can also be located on the inside of the vehicle component (i.e., facing the vehicle interior) and therefore be invisible from outside the vehicle. This has the advantage, for example, that during installation, a technician can identify the deformation area and / or attach the at least one sensor element based on the marking. This enables safe and reliable installation of the sensor system, especially since the detection by the sensor elements depends on an activation device within the vehicle component.In other words, the activation device can be located outside a sensor module in or on the vehicle component, so that during assembly, the exact positioning of the sensor module with its sensor elements relative to the activation device in the deformation area is crucial. In particular, marking the deformation area can also be in the form of a color code, an adhesive strip, a circumferential (especially around the deformation area) step, or the like.

[0019] In particular, it is intended for and / or required for the detection of the sensor elements that at least one inductive, especially metallic, element is provided in the deformation area, e.g., an activation element. The activation element can be, for example, a metal layer or be formed by the vehicle part itself. For example, a vehicle part that is predominantly made of plastic cannot usually cause a significant change in inductance. Therefore, in such a case, an activation element may be provided in the deformation area, especially on or in the vehicle part. The activation element can also be designed, for example, as a metal strip, a chrome layer, or another inductive, especially metallic, coating. Furthermore, the activation element can preferably be located on the inside (i.e., facing the vehicle interior) or on the outside (facing away from the vehicle interior).The activation means should be arranged on the exterior side of the vehicle part. Preferably, the activation means can be formed by the vehicle part itself, for example, if it is made of sheet metal (e.g., in the case of a car body as a vehicle part).

[0020] It is conceivable that the first and second sensor elements are each designed for inductance measurement on a respective inductive activation device, wherein, in particular, the activation device can be arranged in the (respective) deformation area so that the respective deformation can preferably be detected by means of the inductance measurement in order to activate the at least one vehicle function depending on the inductance measurement. For example, each of the activation devices can be assigned to one of the sensor elements and, for this purpose, arranged at a predetermined distance relative to the respective assigned sensor element. The distance (vehicle part distance) must, in particular, be chosen such that a movement of the activation device due to deformation results in a significant change in inductance that can be detected by the respective sensor element.The change in inductance is caused in particular by the fact that the distance between the vehicle part and the corresponding sensor element and the activation means changes during deformation.

[0021] It is also conceivable that the at least one or each deformation area could encompass a section of a (single or individual) vehicle part, particularly an exterior panel, especially outside a door handle. For example, the deformation area could be located below, adjacent to, or behind an associated door handle. This has the advantage that, upon execution of a specific activation action and / or activation pattern at the deformation area, a specific door handle function can be activated as a vehicle function by the sensor elements, without the need to operate the door handle itself. The door handle function could, for example, be the activation of the electric lock to open and / or release the door using the door handle.

[0022] According to the invention, a geometric arrangement of at least three sensor elements is provided, wherein at least the first sensor element is spaced at least one sensor distance from the second sensor element and the other sensor elements, so that the deformation profile can be detected as a function of the geometric arrangement. The geometric arrangement relates in particular to a specific (fixed) geometric arrangement of the sensor elements. For example, the sensor elements can be arranged in a circle or another geometric shape according to the geometric arrangement. Preferably, an activation pattern can be detected which has the geometric shape, in particular a circular sequence of deformations (i.e., a user performs several deformations on the vehicle part, so that the deformations together replicate the geometric shape, in particular a circle).This has the advantage of enabling particularly convenient activation of the vehicle function.

[0023] In particular, it may be possible that the vehicle functions include at least one of the following: Releasing or opening at least one door of the vehicle, in particular by activating an electric door lock; controlling the central locking system of the vehicle; releasing or opening at least one tailgate of the vehicle, in particular by activating an electric door lock; a wake-up signal for a (central) vehicle locking system; initiating an authentication process; releasing or opening at least one glove compartment door of the vehicle, in particular by activating an electric glove compartment lock; activating vehicle lighting; controlling the movement of the vehicle, e.g., a direction of travel and / or initiating a stop of the vehicle, e.g., for a maneuvering and / or automatic parking function of the vehicle; performing an emergency stop of the vehicle.

[0024] For example, activation actions and / or patterns, especially gestures, allow various functions to be intuitively activated from outside the vehicle. This makes it possible, for instance, to safely and reliably control and / or end a parking function from outside the vehicle.

[0025] The vehicle is designed, for example, as a motor vehicle and / or passenger vehicle and / or electric vehicle and / or self-driving (autonomous) vehicle.

[0026] Preferably, the at least one first and second sensor element, and in particular further sensor elements, can be arranged in a geometric configuration with fixed sensor distances to one another, and are preferably rigidly connected to each other via a housing, and in particular are arranged at least partially according to a geometric shape, especially circular, rectangular, polygonal, row-shaped, rhombic, trapezoidal, square, elliptical, rhombus-shaped, star-shaped, or cross-shaped. This has the advantage that activation patterns (e.g., gestures) corresponding to this geometric shape can be captured or detected. The deformation pattern can, for example, replicate the geometric shape, e.g., through a sequence of deformations in the (respective) deformation areas, in order to activate a specific vehicle function. For example, if...Deformations are generated in the deformation areas such that the temporal sequence of deformations replicates the geometric shape, allowing a specific activation pattern corresponding to this geometric shape to be detected. Alternatively or additionally, the sensor elements can be arranged as a matrix, enabling different deformation sequences with varying geometric shapes. It may also be possible to detect different activation patterns (gestures) with different geometric shapes based on the sensor element data, despite the fixed geometric arrangement. This can be achieved, for example, by comparing the detection signals of the respective sensor elements.

[0027] It is conceivable that at least one sensor spacing between the sensor elements is adapted to a geometric arrangement, and preferably one vehicle part spacing of the respective sensor elements to a vehicle part is adapted to the vehicle part in such a way that the vehicle part spacing is essentially the same for all sensor elements.

[0028] This ensures reliable data acquisition. In particular, the vehicle part spacing is adjusted to allow inductance measurement at an activation device on the vehicle part.

[0029] Furthermore, the invention may provide that the respective sensor elements are arranged at a distance from the respective vehicle part deformation areas, in particular an inner side of a vehicle part facing the vehicle interior, so that the deformation in the respective deformation area and / or the temporal progression of these deformations can be evaluated by the processing device. The arrangement and / or fastening to the vehicle is effected, for example, by at least one retaining element, in particular by at least one adhesive tape, at least one snap-fit ​​element, at least one screw, at least one rivet connection, or the like. The arrangement and / or fastening of the sensor elements (in particular the sensor system and / or sensor module) is effected, for example, via a mounting structure of a housing.Detachable or non-detachable, particularly in or within the vehicle part, or on the vehicle part and / or the vehicle. Specifically, the arrangement and / or attachment takes place on an inner surface of the vehicle part and / or on or in a sheet metal frame of the vehicle part. For example, the sensor module can be attached (as a single component) to an interior-facing area of ​​the vehicle part, such as a sheet metal panel or similar.

[0030] Furthermore, it can be advantageous within the scope of the invention that the sensor elements are each designed as an LDC sensor element and / or an inductive sensor or the like, in particular as an (LDC) coil, so that the sensor system is designed as an LDC sensor system and / or an inductive sensor system, especially for inductance measurement. (The abbreviation LDC stands for "Inductance-To-Digital Converter"). The at least one sensor element serves in particular for the (indirect) measurement of deformation and / or contact on the vehicle part in the deformation area. Thus, the deformations can be reliably detected.

[0031] Preferably, the at least one sensor element and / or the sensor system, in particular an LDC sensor system, serves to detect at least one change in inductance, i.e., in particular for inductance measurement. This normally requires various components and / or circuits, which, in the case of the LDC sensor, are combined on a single chip or in an integrated circuit. The LDC sensor and / or the sensor system is, for example, designed to simultaneously measure the impedance and the resonant frequency of an LC resonant circuit. The sensor system is preferably insensitive to external influences such as moisture or contamination in the deformation area. Consequently, false detection due to influences such as rain, which can lead to malfunctions in, for example, capacitive sensors, can be reliably avoided. False detection due to external influences that exert a force on the vehicle component can, for example, be prevented by...This avoids situations where only a portion of the vehicle component exhibits the deformation range and / or where appropriate threshold values ​​are used that are specific to the respective activation action. The LDC sensor system also offers the advantages of being highly sensitive to deformations, thus enabling very fast and reliable detection of the activation action (i.e., the deformation or deformation progression). The sensor system has, for example, a resolution of less than one micrometer with a bit depth of at least 16 bits or at least 24 bits for quantizing the measured inductance values.

[0032] It may optionally be possible for at least one inductive activation device to be attached to or integrated in a vehicle part, in particular an exterior panel of the vehicle, at such a distance from the sensor elements that the respective deformation, in particular a deformation profile, can be detected by the sensor elements in the deformation areas or the at least one deformation area by means of an inductance measurement at the at least one activation device. In particular, the deformation profile can be influenced and / or caused by moving different activation devices sequentially over time (through the deformations), and thus this movement profile or sequence of movements (or activation sequence of the activation devices) replicates a geometric shape.Since this sequence of movements is determined by the order in which a user performs the deformations in the deformation areas using the activation means, the user can perform a variety of different activation patterns, especially gestures, to activate various vehicle functions.

[0033] For example, the activation pattern or gesture can also be used to enter a specific code, so that the vehicle function is only activated if the activation pattern or gesture matches a predefined code. In this way, a pattern can be used as a "password" for the vehicle function.

[0034] Furthermore, it is optionally provided that, for detection, particularly as an inductance measurement, an activation element is provided in each of the deformation areas. This activation element is designed as an inductive element, particularly a metallic element, preferably as a metal foil and / or as a metallic and / or chrome-plated surface or coating of a vehicle part, in particular an interior (and especially sensor element-side) inner surface of an exterior panel of the vehicle. In particular, the activation element can be arranged on the vehicle (interior) side of the vehicle part and, if necessary, thus be located outside the sensor system. For example, the sensor system is then adapted to the activation element and is attached to the vehicle part with the activation element during installation.

[0035] It is also conceivable that a vehicle part, in particular an outer panel of the vehicle, is designed to be elastically deformable (at least predominantly) in the (respective) deformation area, so that deformation sequences in the deformation areas (as a deformation profile) can preferably be detected by means of the sensor elements, in particular a (respective) inductance measurement.

[0036] For example, the processing device may be electrically connected to the respective sensor elements via conductors on a printed circuit board. In particular, at least some of the sensor elements and / or the processing device may be attached to the circuit board, for example, by soldering or as an SMD (surface-mounted device) component. The processing device and / or an associated interface device may be implemented, for example, as an integrated circuit, in particular as a processor and / or microcontroller. This enables reliable and rapid data processing.

[0037] Furthermore, a housing may be provided, in particular for at least partially accommodating and / or arranging the sensor elements and / or the processing device and / or a printed circuit board, wherein the printed circuit board is preferably overmolded and / or potted with potting compound within the housing, and wherein the housing preferably has a mounting structure for attaching the sensor system and / or the sensor elements and / or the sensor module to the vehicle, in particular to a vehicle component. The sensor system can preferably be attached internally to an outer panel, a vehicle sheet, a plate, or a structural surface of the vehicle, which exemplarily constitute the aforementioned vehicle component. Consequently, the vehicle components simultaneously represent the deformation zone and are accessible to a user from the outside (opposite side of the vehicle component's surface to the sensor system).The housing and / or mounting structure and / or a spacer can be made of plastic, particularly as an injection-molded part. The mounting structure can be designed, for example, to accommodate and / or attach retaining devices to ensure reliable attachment to the vehicle.

[0038] Advantageously, the invention provides a housing that includes at least one spacer, such that, particularly when the housing is attached to the vehicle part, the sensor elements are arranged at a distance from their respective activation means in the deformation zone. This ensures that any deformation in the deformation zone results in a relative movement of the activation means with respect to the spaced sensor element. In particular, the spacer is designed on the housing, preferably as a projection or the like, such that a predetermined distance (within a tolerance range) between the sensor elements and the respective activation means is maintained when the housing is attached to the vehicle (part). This ensures reliable detection and easy installation.In particular, an area on the vehicle and / or vehicle part is visibly marked where the housing with the mounting structure is positioned, thus further simplifying assembly. For example, the activation element can also be at least partially the wall or sheet metal of the vehicle part.

[0039] According to an advantageous embodiment of the invention, a housing can be provided which is attached to a vehicle part by gluing and / or screwing and / or clipping and / or snapping, in particular by means of a mounting structure of the housing. This enables simple and secure installation.

[0040] Furthermore, within the scope of the invention, it is conceivable that the sensor elements each comprise at least one electrical coil, in particular an LDC coil, for generating and / or detecting a magnetic field. In particular, this allows for the detection of changes in inductance. Specifically, a deformation within a defined deformation range is detected when the values ​​of a detection signal from the sensor element associated with that range exceed a certain threshold. This has the advantage that the various deformations within the different deformation ranges can be used in a simple manner to determine the deformation profile.

[0041] Within the scope of the invention, an interface device may be provided to transmit the results of the deformation analysis to a vehicle electronics system, particularly a central one. Preferably, the interface device is configured for connection to a vehicle bus system, most preferably a LIN (Local Interconnect Network) or CAN (Controller Area Network) bus, a carrier frequency system, powerline communication, a pattern system, or an open collector. The carrier frequency system is, in particular, a data transmission system that utilizes the vehicle's existing electrical network for data transmission. This enables particularly space-saving data transmission.

[0042] Preferably, the sensor elements can be connected in such a way that the sensor module and / or sensor system forms a series sensor (or a sensor array). Accordingly, the sensor elements can, for example, be arranged in a series and / or rigidly connected to one another.

[0043] Furthermore, the invention may provide that the sensor system can be connected to a transmission system, in particular a carrier frequency system, via an interface device, so that both a power supply for the sensor system and a data connection and / or data transmission, in particular between the processing device and vehicle electronics, are provided via the transmission system, in particular via identical electrical conductors. This enables a reduction in installation space that would otherwise be required for a dedicated bus system.

[0044] In another possibility, the activation means can be designed as an electrically conductive film and / or an electrically conductive coating and / or at least one electrically conductive element, preferably made of metal, preferably elastically deformable and / or completely galvanically isolated, particularly from the sensor elements, and is particularly preferably arranged (especially on the inside) on the vehicle part and / or on a structural modification of the vehicle part. This achieves the advantage that a minor and cost-effective modification of the vehicle part is sufficient for detecting a change in inductance.

[0045] Preferably, a structural adaptation may be provided in the deformation area, which is designed, for example, as a recess or material weakening and / or reduced wall thickness of the vehicle part, such that, preferably, when force is applied to the deformation area (originating from the exterior of the vehicle), a relative movement of the activation means occurs with respect to at least the associated sensor element. Preferably, the vehicle part exhibits sufficient deformability and / or elasticity in the area of ​​the structural adaptation and / or in the deformation area to allow for this relative movement. The deformations are further preferably elastic.

[0046] Furthermore, it is advantageous if, within the scope of the invention, an area between the respective sensor elements and / or at least one associated activation agent is at least partially filled with a filling element, in particular a potting compound. This enables reliable detection, especially by providing protection against external influences, e.g., penetrating moisture.

[0047] The invention also relates to a sensor module for activating at least one vehicle function of a vehicle, preferably for activating at least one electric lock of the vehicle, with at least one first and at least one second sensor element, and with a housing which has at least one mounting structure.

[0048] It is provided that the sensor elements are rigidly connected to one another via the mounting structure of the housing, so that the sensor elements form a geometric arrangement, wherein the sensor module can be attached to a vehicle part by the mounting structure in such a way that the geometric arrangement corresponds to at least one deformation area on the vehicle part. Thus, the sensor module according to the invention offers the same advantages as those described in detail with reference to a sensor system according to the invention. Furthermore, the sensor module according to the invention can preferably be configured according to a sensor system according to the invention.

[0049] According to the invention, the at least first and second sensor elements are each configured for inductance measurement, such that a measurement result of the inductance measurement is specific for the deformation in a respective deformation area on an outer panel of the vehicle. A geometric arrangement of at least three of the sensor elements is provided, wherein at least the first sensor element is arranged at least one sensor distance apart from the second sensor element and the other sensor elements, so that the deformation profile can be detected as a function of the geometric arrangement.

[0050] It may also be possible that the sensor module is designed as a separately handleable module, preferably for attachment to an inside of the vehicle part, preferably an (interior side of a) exterior panel and / or a door handle of the vehicle.

[0051] The invention also relates to a vehicle with at least one sensor system and / or at least one sensor module according to the invention. It is provided that a first sensor system and / or first sensor module is arranged in a first area of ​​the vehicle, in particular in a rear area of ​​the vehicle, and a second sensor system and / or second sensor module is arranged in a second area of ​​the vehicle, in particular in a side area of ​​the vehicle, so that deformation profiles in the different areas of the vehicle can be detected, in particular to activate different vehicle functions. Thus, the vehicle according to the invention offers the same advantages as those described in detail with reference to a sensor system and / or sensor module according to the invention.

[0052] A further advantage can be achieved within the scope of the invention if the different vehicle functions each include the activation of at least one electric lock, in particular for releasing and / or opening movable parts of the vehicle with the respective vehicle components. For example, the various sensor systems and / or sensor modules can also serve to activate different electric locks, e.g., in the rear and / or side area of ​​the vehicle. The invention also relates to a method for activating at least one vehicle function of a vehicle, preferably for activating at least one electric lock of the vehicle, with at least one first and at least one second sensor element.

[0053] The following steps are carried out: a) Performing a first detection by the first sensor element, wherein the first detection is specific for a first deformation in a first deformation area on the vehicle, b) Performing at least a second detection by the at least second sensor element, wherein the at least second detection is specific for at least a second deformation in at least a second deformation area on the vehicle, c) Evaluating the first and the at least second detections, such that at least one deformation profile is determined, d) Activating the at least one vehicle function based on the determined deformation profile.

[0054] According to the invention, the at least first and second sensor elements are each configured for inductance measurement, such that a measurement result of the inductance measurement is specific for the deformation in a respective deformation area on an outer panel of the vehicle. A geometric arrangement of at least three of the sensor elements is provided, wherein at least the first sensor element is arranged at least one sensor distance apart from the second sensor element and the other sensor elements, so that the deformation profile can be detected as a function of the geometric arrangement.

[0055] The inventive method thus offers the same advantages as those described in detail with reference to an inventive sensor system and / or sensor module and / or vehicle. Furthermore, the method may be suitable for operating an inventive sensor system and / or sensor module and / or vehicle.

[0056] It is also conceivable that a further step c') is provided after step c) and / or before step d), wherein, according to this further step c'), at least one acquisition signal from the respective (first and at least second) acquisition is evaluated. In particular, the respective sensor elements serve for inductance measurement, so that the acquisition signals are specific for measured values ​​of the inductance measurement. Preferably, these measured values ​​can then be compared with (each) at least one predefined target value (e.g., a target force). For example, the peak values ​​of the acquisition signals are determined in order to ascertain a force effect due to deformation and / or to compare it with the target value.

[0057] Furthermore, it may be possible to evaluate the first and / or at least the second data acquisition in such a way that at least one force influence (e.g., quantitatively) is determined, i.e., in particular measured, which correlates with at least one of the respective deformations, so that the activation of the at least one vehicle function preferably occurs based on the determined force influence. For example, a specific force influence is correlated with the respective deformation in that the specific force influence (according to a specification) is considered necessary for carrying out the deformation. The specification is, for example, pre-stored information for parameterizing the force measurement.

[0058] In particular, it may be possible that the evaluation according to step c) includes an analysis of the respective data records, allowing the evaluation of the force exerted by each deformation. For this purpose, peak values ​​of the respective data records are determined and / or compared with at least one target value. This target value could include, for example, predefined target values ​​for the force exerted. The force exerted by each deformation can also be quantitatively determined. Furthermore, the activation of at least one vehicle function can be triggered based on a result of the analysis and / or the determined force exerted.

[0059] Preferably, the measurement is an inductance measurement, particularly at an inductive activation device (in the deformation zone). The measurement is especially preferred for detecting even the smallest deformation in the deformation zone, particularly of the vehicle part, preferably a sheet metal panel or an outer cladding. The deformation is, in particular, light pressure with a finger on the outside of the vehicle part, e.g., by a user.

[0060] Within the scope of the invention, it may be provided that the evaluation according to step c) includes a comparison of the first with the at least second detection, such that the deformation profile is specific to a gesture of a vehicle user. This enables reliable and convenient control of vehicle functions.

[0061] A further advantage is that in step c) a first deformation profile is distinguished from a second deformation profile, whereby, according to step d), a first vehicle function is activated when the first deformation profile is determined, and a second vehicle function is activated when the second deformation profile is determined. The same can apply to further vehicle functions and deformation profiles in order to control a large number of vehicle functions.

[0062] It is also advantageous if, according to step c), at least a first detection signal and at least a second detection signal, and preferably at least a third and fourth detection signal, from different sensor elements are compared with each other to determine the deformation process, wherein preferably the detection signals are time-dependent or include time-dependent information, so that a temporal deformation pattern is determined in particular by evaluation.

[0063] In particular, it may be possible that the detection signals exhibit a characteristic pattern during each deformation within the respective deformation area. This pattern could, for example, be the exceeding of a threshold value by at least one detection value of the corresponding signal. Thus, by evaluating the occurrence of these patterns, a temporal sequence of deformations can be established, and the deformations can be assigned to the respective sensor elements, in order to determine a specific activation pattern.

[0064] Furthermore, within the scope of the invention, it is optionally possible that, for the respective sensor elements, a change in distance between at least one inductive activation means and the respective sensor element is evaluated to determine a deformation and / or the deformation profile. For example, a deformation is detected when a minimum change in distance is present. The minimum change in distance is, for example, in a range between 0.1 and 10 mm, preferably 0.5 and 8 mm, and more preferably 1 and 6 mm. Thus, a threshold value can also be defined to further increase the reliability of the detection. Depending on the detected deformations, a deformation profile can then be determined, for example, according to step c).

[0065] Preferably, the deformation pattern can be specific to a mechanical gesture on a vehicle part, wherein, in particular, the mechanical gesture leads to elastic deformation of the vehicle part and / or movement of at least one activation means relative to at least one of the sensor elements. The mechanical gesture is thus, for example, a deformation gesture on the vehicle part. The deformation can be elastic and / or so minor that it is not, or hardly, perceptible or visible to the user from the outside.

[0066] Furthermore, the invention may provide that in step c), a first deformation in a first deformation area is distinguished as a first activation action from a second deformation in a second deformation area as a second activation action, wherein the deformation profile is specific for a sequence of activation actions and / or for an activation movement, such that different successive activation actions (and / or activation movements) each form different gestures to activate a vehicle function associated with the respective gesture in step d) based on the deformation profile. In particular, the successive activation actions may also include a swipe along the deformation area (by a user), e.g., from left to right or from right to left, or the like. For example, the deformation profile corresponds to a detection sequence (i.e., for example,(A deformation is detected first based on the second measurement, and then a deformation is detected based on the first measurement). Furthermore, different measurement sequences may indicate different gestures.

[0067] Furthermore, within the scope of the invention, it is conceivable that in step c) a speed of execution and / or sequence of activation actions is determined based on the detections and / or the deformation profile, wherein preferably the activation actions each comprise at least one deformation in at least one of the deformation areas. For example, a specific activation pattern (i.e., also a gesture) can also be characterized by a specific speed during the execution of the deformations. In particular, a frequency of positive detections of the deformations by the sensor elements is specific to this speed and is evaluated, for example, in step c).

[0068] It may optionally be possible (preferably according to step c) ) to distinguish an activation movement and / or sequence of activation actions (in particular an activation pattern) in a first direction from an activation movement and / or sequence of activation actions (in particular an activation pattern) in a second direction, particularly based on the evaluation, wherein preferably a circular activation movement and / or sequence is distinguished from a linear activation movement and / or sequence in order to activate different vehicle functions assigned to each. In particular, it is possible that the activation actions and / or the activation movements each comprise at least one deformation in at least one of the deformation areas. For example, by comparing pre-stored information about a geometric arrangement of the sensor elements with a detection sequence of the sensor elements (i.e.,A specific activation pattern can be detected based on a sequence of deformation detections by the sensor elements.

[0069] Another possibility is that at least the evaluation according to step c) is carried out by a processing device, wherein the processing device provides an evaluation result of the evaluation according to step c) to vehicle electronics, in particular via an electrical interface and / or interface device, wherein the evaluation result preferably indicates the vehicle function to be activated. The evaluation result can, for example, include a result of an evaluation of detection signals from the respective sensor elements. In other words, it may be possible that not (only or at all) the "pure" detection signal of the sensor elements is provided by the interface or the interface device, but rather a result of the evaluation of these detection signals, in particular taking into account a gesture to be detected or a deformation profile. For example,The evaluation result includes information about the deformation process or a detected activation pattern (or gesture). For this purpose, the processing device can, for example, be connected to a non-volatile data storage device containing information readable by the processing device about specifications for the possible activation patterns or gestures (e.g., information about the geometric arrangement of the sensor elements). The evaluation result can also simply indicate whether a specific activation pattern or gesture was detected or not. Thus, the logic required for the evaluation can already be integrated into the sensor module or sensor system. This ensures adaptability for different vehicles.

[0070] Furthermore, the invention may provide that at least the evaluation according to step c) is carried out by a processing device, wherein the processing device is preferably designed according to a sensor system according to the invention.

[0071] Furthermore, it is conceivable that the deformation (i.e., an indentation into the vehicle part) causes a movement of the activation agent in a first direction.

[0072] In particular, the deformation pattern and / or the detection of the sensor elements depend on the position of the deformation, whereby the position varies in one direction orthogonal to the first direction when the gesture is performed. For example, the movement of the activation means causes a relative movement of the activation means to at least one of the sensor elements. In particular, at least one activation means can be provided for each sensor element and deformation area, such that a relative movement of a first activation means to a first sensor element for a first deformation area affects the first detection, and a relative movement of a second activation means to a second sensor element for a second deformation area affects the second detection.In particular, the activation means assigned to the respective sensor elements and / or deformation areas are arranged closer to the respective sensor element and / or deformation area than all other activation means for other sensor elements and / or deformation areas.

[0073] Furthermore, it is conceivable that at least one connection element is connected to an interface device, wherein the connection element is, for example, designed as a plug and / or integrated into the housing. In particular, the connection element is arranged in the area of ​​a cable harness.

[0074] Furthermore, it may be possible that the printed circuit board (PCB) is overmolded and / or potted in the housing, the housing preferably being made of plastic.

[0075] It is conceivable that a vehicle part distance A (i.e., a distance between the respective sensor elements and a vehicle part and / or deformation area and / or activation means) lies at least or exactly or at most in a range of 0 mm to 10 mm, preferably 2 mm to 5 mm, more preferably 0.25 mm to 4 mm, more preferably 1 mm to 3 mm.

[0076] Preferably, it may be possible that a sensor spacing B (i.e., a distance between adjacent sensor elements of the sensor system) lies at least or exactly or at most in a range of 1 cm to 10 cm, preferably 2 cm to 8 cm, preferably 3 cm to 6 cm.

[0077] Further advantages, features and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings.

[0078] They show: Figures 1-3 schematic views of a vehicle with a sensor system according to the invention, Figures 4 and 5 schematic views of parts of a sensor system or a sensor module according to the invention, Figures 6 and 7 further schematic views of parts of a sensor system or a sensor module according to the invention, Figures 8 and 9 further schematic views of parts of a sensor system or a sensor module according to the invention, Figures 10 and 11 further schematic views of parts of a sensor system or a sensor module according to the invention, Figure 12 a schematic sectional view of parts of a sensor system according to the invention, and Figure 13 a further schematic view of a sensor system according to the invention, Figure 14 a schematic representation for visualizing a method according to the invention.

[0079] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0080] In Figure 1 Figure 1 schematically shows a side view of a vehicle 1 according to the invention. Also schematically illustrated are door handles 10 of the vehicle 1, movable parts 2 of the vehicle 1, and an outer panel 4 or at least one vehicle part 4 of the vehicle 1. Furthermore, vehicle electronics 6 are shown, which are preferably arranged inside the vehicle 1. In the exterior of the vehicle 1, a user 18 is also shown, who can, for example, perform a deformation on the vehicle part 4 from the outside.

[0081] In Figure 2An exemplary integration of a system 200 according to the invention into the vehicle 1 is shown. For this purpose, several sensor elements 20 can be arranged on and / or integrated into the vehicle 1. For example, a first sensor element 20a is arranged in a rear area of ​​the vehicle 1, a second sensor element 20b in the area of ​​a rear side door of the vehicle 1, a third sensor element 20c in the area of ​​a front side door of the vehicle 1, and a fourth sensor element 20d in the area of ​​a glove compartment of the vehicle 1. Optionally, the aforementioned sensor elements 20 can form parts of respective sensor modules 300. It is further shown that each sensor element 20 is associated with an electrical locking device 3, in particular an electrical lock 3. Accordingly, at least one deformation in the area of ​​the respective sensor elements 20 can lead to the activation of the respective electrical locking device 3.

[0082] Furthermore, in Figure 2 It is shown that the sensor elements 20 can be connected to each other and / or to vehicle electronics 6 via a transmission system 7, in particular a bus system 7.

[0083] In Figure 3The schematic diagram shows that multiple sensor systems 200 and / or sensor modules 300 can be arranged in different areas of the vehicle 1. For example, one sensor module 300 or sensor system 200 is located in the rear area, another sensor module 300 or sensor system 200 is located in the area of ​​a glove compartment in the interior of the vehicle 1, and two further sensor modules 300 or sensor systems 200 are located in the side area at the respective doors of the vehicle 1. Here, too, it is possible that at least one associated electrical locking device 3 can be activated by at least one deformation in the area of ​​the respective sensor elements 20 of the respective sensor modules 300 or sensor systems 200.

[0084] The Figures 4 and 5 Figure 1 schematically shows a structure of a system 200 or a sensor module 300 according to the invention, in particular according to a first embodiment. Figure 4The diagram shows a top view (on the left) and a sectional view through plane CC of sensor module 300 (on the right). Figure 5 Figure 1 shows a rear view (on the left) and a perspective view (on the right) of the sensor module 300 according to the invention. It can be seen that the sensor module 300 according to the invention has a total of four sensor elements 20, which are arranged relative to each other according to a specific geometric arrangement 93. In particular, the sensor elements 20 are arranged in a cross shape, with a first sensor element 20a and a third sensor element 20c being arranged on opposite sides, and a second sensor element 20b and a fourth sensor element 20d also being arranged on opposite sides (see Figure 1). Figure 5 ). Furthermore, according to the Figures 4 and 5It is evident that the sensor elements 20 are connected to each other by a housing 90, in particular by a spacer 92 and / or a mounting structure 91. The spacer 92 also serves, if necessary, to ensure a required vehicle part distance A when mounted on a vehicle part 4. For this purpose, the spacer 92 connects the sensor elements 20 to the mounting structure 91 in such a way that the mounting structure 91 protrudes beyond the sensor elements 20. During installation, the sensor module 300 can be connected directly to the vehicle part 4 (or another area of ​​the vehicle 1) via the mounting structure 91. In particular, only the mounting structure 91 makes direct contact with the vehicle 1 or the vehicle part 4.The sensor module 300 is mounted on the vehicle 1 in such a way that a deformation-side area 21 of the sensor elements 20 points towards the deformation area 30 (and / or towards the vehicle part 4), and preferably a vehicle (interior)-side area 22 of the sensor module 300 points towards the interior of the vehicle 1. This ensures that a Figure 5 The deformation-side area 21 of the sensor module 300 or the sensor elements 20 shown (on the left) has the necessary minimum distance to an activation means 31 in the deformation area 30 in order to perform an inductance measurement. This inductance measurement is specific for a deformation in the deformation area 30.

[0085] To evaluate this inductance measurement, a processing device 80 is provided. This processing device 80 can be connected, for example, via the conductor tracks of a printed circuit board 81 to the sensor elements 20 and / or to an interface device 40. The interface device 40 serves, for example, to provide an evaluation result from the processing device 80 to a vehicle electronics system 6 of the vehicle 1 via at least one electrical connection element 96, in particular an electrical contact and / or an electrical cable. For this purpose, the electrical connection element 96 is, for example, connected to a bus system 7 of the vehicle 1.

[0086] Furthermore, to ensure protection against external influences such as moisture, a potting compound 94 may be provided. For example, the circuit board 81 can thus be potted in the housing 90.

[0087] In the Figure 6 and7 Schematic representations of parts of a sensor system 200 or a sensor module 300 according to the invention are shown in different views. For example, in Figure 6 (On the left) a top view of a vehicle interior area 22 of sensor module 300 is shown, and (on the right) a sectional view through plane EE is shown. Figure 7Figure 1 shows (on the left) a view of a deformation-side area 21 of the sensor module 300 and (on the right) a perspective view of the sensor module 300 according to the invention. Here, too, a housing 90 is provided for the sensor module 300 according to the invention, which comprises at least one spacer 92 and at least one mounting structure 91. The arrangement of the sensor elements 20, which is determined in particular by the shape of the housing 90, represents a triangular geometric arrangement 93. Preferably, the sensor system 200 or the sensor module 300 according to the invention is located in the Figure 6 and 7 designed according to a second design variant.

[0088] In the Figures 8 and 9Further views of a sensor system 200 or a sensor module 300 according to the invention are shown, which are preferably designed according to a third embodiment. In this view (on the left side) Figure 8 A top view of a vehicle-side area 22 (i.e., a vehicle interior-side area 22) and (on the right) a sectional view through a section plane GG are shown. Figure 9 The figures show (on the left) a view of a deformation-side area 21 and (on the right) a perspective view of the sensor system 200 or sensor module 300 according to the invention. The geometric arrangement 93 is shown as a series or as a row.

[0089] In the Figures 10 and 11 Further views of a sensor system 200 or a sensor module 300 according to the invention are shown, in particular a fourth embodiment being illustrated. Figure 10 (On the left) a view of a deformation-side area 21 is shown, and further (on the right) a sectional view through a plane DD. The geometric arrangement 93 is also in series, with only three sensor elements 20 provided. It can also be seen that a connection element 95 is not designed as a cable, but as a plug element, in particular a connector. Furthermore, a fastening structure 91, as shown in the Figures 10 and 11 It can be seen that at least one clip foot is designed. This enables, in particular, a secure and / or releasable connection to the vehicle 1, especially to the vehicle part 4, preferably to a corresponding vehicle mounting structure.

[0090] Optionally, according to the illustrated embodiments, the sensor elements 20 can be at least partially surrounded or overmolded by the housing 90, so that preferably the coils of the sensor elements 20 are protected. This is also the case, for example, in Figure 9 recognizable.

[0091] In Figure 12Figure 1 schematically shows a cross-sectional view through parts of a sensor system 200 or a sensor module 300 according to the invention. It can be seen that the adjacent sensor elements 20 can have a sensor distance B from each other, so that detection in adjacent or spaced-apart deformation areas 30 is possible. For this purpose, at least one activation means 31, which is inductively designed, can be provided in each of the deformation areas 30. This enables inductance detection by the sensor elements 20. The activation means 31 can, for example, be arranged on an inner surface 5 (on the vehicle interior side) of a vehicle part 4, in particular an outer panel and / or body of the vehicle 1. The force that leads to deformation in the deformation area 30, for example by pressing on it by a user 18, can, for example, be...on the outside of the vehicle part 4 (this corresponds to the deformation-side area 21' of the vehicle part 4, wherein a deformation-side area 21 of the sensor module 300 according to the invention is also oriented in the direction of this force action).

[0092] In Figure 13 A deformation profile V is shown schematically. For example, according to a circular deformation profile V, deformation can first occur in a first deformation area 30a, then in a second deformation area 30b, then in a third deformation area 30c, and finally in a fourth deformation area 30d. Accordingly, when evaluating the detection of the sensor elements 20, a deformation would first be detected in a first sensor element 20a, then in a second sensor element 20b, then in a third sensor element 20c, and finally in a fourth sensor element 20d. Furthermore, it is assumed that... Figure 13 It is clear that a geometric arrangement 93 of the sensor elements 20 corresponds to the deformation areas 30 on the vehicle part 4. The arrangement of the deformation areas 30 corresponds, for example, to a cross shape, which corresponds, for example, to a cross-shaped (cross-like) geometric arrangement 93 (cf. Figure 5 ). This also makes it clear that a circular gesture (i.e. a circular deformation pattern V) can also be detected by the cross-shaped geometric arrangement 93.

[0093] In Figure 14The schematic diagram illustrates a method 100 according to the invention, in which a first detection signal 110a, a second detection signal 110b, a third detection signal 110c and / or a fourth detection signal 110d can be evaluated for the evaluation of the detection by the sensor elements 20, each of which is assigned to or provided by the corresponding first to fourth sensor elements 20. Based on the respective detection signals 110, the deformation in the corresponding first to fourth deformation areas 30 can be detected.
