Description

Technical Field

[0001] The present invention relates to an operating device, a vehicle, and a method. Background Technology

[0002] Existing technology provides knowledge of vehicle operating mechanisms where a user's actions trigger vehicle functions. One known method involves using proximity sensors to detect a user's approach and, for example, unlock a door, allowing the user to comfortably open the door. Such proximity sensors are typically integrated into door handles. Due to their geometry, door handles offer the advantage of allowing for simple encapsulation of the sensor device to protect it from moisture and other environmental factors. However, if the sensor device should be mounted on other vehicle components, such as body panels, this encapsulation cannot be readily applied to the body panels due to their flattened shape. Summary of the Invention

[0003] The objective of this invention is to at least partially eliminate the aforementioned disadvantages known from the prior art. In particular, the objective of this invention is to allow for the sealing of sensor units, preferably located on the flat vehicle portion outside the vehicle door handle, while improving both manufacturing possibilities and / or operational comfort.

[0004] Hereinafter, the features and details described with respect to the operating device of the present invention are obviously also applicable to the vehicle of the present invention and / or the method of the present invention, and vice versa; therefore, the disclosures of various aspects of the invention are always mutually referential or can be mutually referenced.

[0005] According to a first aspect of the invention, an operating device for triggering vehicle functions by a user is provided. The operating device has a flat liner for a vehicle portion of the vehicle. The liner includes an inner liner side and an outer liner side. Additionally, the operating device has an electronic unit having a sensor unit for detecting user operating behavior to trigger vehicle functions. The electronic unit has an electronic device outer side and an electronic device inner side, wherein the electronic device inner side faces the electronic device outer side. Furthermore, the electronic unit is oriented with the electronic device outer side facing the inner liner side and is disposed on the liner to detect operating behavior on the outer side of the liner. A first housing portion for protecting the inner side of the electronic device is fixed to the liner such that the liner and the first housing portion form a complete housing for protecting the electronic unit.

[0006] Vehicle functions may include, for example, unlocking door locks, opening doors, and / or activating lighting and / or electrical equipment. The vehicle component may include, for example, external or internal components of the vehicle.

[0007] The flat design of the trim piece can specifically refer to the trim piece having a flat extension, particularly in the form of a cover. For example, the trim piece can be designed to be thin-walled. The trim piece can be used, particularly, as a panel for a vehicle body component. For example, the trim piece can form the outer surface of a vehicle part. This outer surface can be an interior or exterior surface of the vehicle. Preferably, the trim piece can form the visible surface of a vehicle part. For example, the trim piece can be arranged, particularly with respect to the outer area of ​​the vehicle, behind a window. In this case, the operating device is preferably mounted on a door, particularly a side door and / or a sliding door. This allows optical and / or electromagnetic signals to be transmitted to a user located in front of the vehicle part, and / or signals from the user to be received via a sensor unit. Preferably, the trim piece can be integrated into the appearance of the vehicle body surface and / or the vehicle body surface, particularly to enable the opening of the vehicle side door as a function that can be triggered by an operational action. It is conceivable to integrate the trim piece into the B-pillar of the vehicle. Thus, in this case, the operating device can optionally be mounted on the B-pillar. In particular, the trim piece is made of or made of plastic. The lining can be designed without handles and / or switches using this sensor unit. Specifically, the inner side of the lining is opposite to the outer side of the lining. For example, the vehicle section can have a lining cavity in which electrical components can be arranged. Here, the inner side of the lining can be oriented particularly towards the lining cavity.

[0008] The electronic unit may have multiple printed wires and / or preferably semiconductor elements for processing electrical signals. Furthermore, the electronic unit may have a power supply for powering the sensor unit and / or an electrical connector for connecting to the vehicle's power supply. For example, it is conceivable that the housing has a cable outlet through which a cable can extend from the electronic unit to the outside of the housing. This ensures electrical connection between the electronic unit and the vehicle's electronics and / or the vehicle's power supply. The electronic unit preferably has a flat extension. In particular, the longitudinal side of the electronic unit may be vertically and / or horizontally oriented on the vehicle portion. The inner and outer sides of the electronic device may, for example, each include the side of the electronic unit's circuit board where electrical components are housed. In particular, the inner side of the electronic device is opposite to the outer side of the electronic device with respect to the electronic unit. The inner side of the electronic device may also be oriented away from the lining. Here, the sensor unit is preferably oriented such that, especially when the user is located outside the vehicle's electronics or near the vehicle, operational behavior outside the electronic device can be detected. "The ability to detect operational behavior on the outer side of the lining" specifically refers to the ability to detect operational behavior on the surface of the outer side of the lining, and / or the ability to detect operational behavior at a distance from the outer surface of the lining. It is conceivable that the sensor unit is designed, for example, for capacitive, inductive, and / or optical measurement of the operational behavior and / or detection of the operational behavior by means of ultrasound. The sensor unit is preferably designed for motion recognition, especially gesture recognition, at a distance of 1 to 20 cm, preferably 2 to 15 cm, more preferably 5 to 10 cm from the operating device.

[0009] The first housing portion can be secured to the liner directly or indirectly. For example, the first housing portion can be constructed by a cover fixed to the liner with a sealant. On the liner, the first housing portion can be tightened or threaded. This provides an advantageous method of fixation, especially under preload. However, it is also conceivable that the first housing portion is applied to the electronic unit and the liner in at least a partially liquid form. In particular, the housing thus forms a tight-fitting shell. It is preferred that the liner and / or the first housing portion and the electronic unit be designed such that the electronic unit can be arranged between the liner and the first housing portion in at most two orientations, preferably only one orientation. For this purpose, the electronic unit and the liner and / or the first housing portion can have auxiliary positioning mechanisms, particularly in the form of asymmetrical grooves and / or protrusions. This visually prevents incorrect installation.

[0010] Furthermore, in the operating device of the present invention, it is conceivable that the sensor unit, electronic unit, and / or housing are at least partially or completely symmetrically configured, particularly about the central plane of the operating device, thereby allowing the operating device to be optionally mounted on two opposing vehicle sides. For example, only the control unit of the electronic unit can be reprogrammed for application on different vehicle sides. It is also conceivable that a switch can be used to determine the left- or right-hand arrangement in the direction of travel. Depending on the vehicle side, for example, the direction of the operating action to trigger the vehicle function and / or the display process of the indicator unit can be determined. In the case of sliding doors on both sides, for example, the two doors can open toward the rear of the vehicle, thus anticipating mirror-image operating actions along the opening direction for automatically opening each sliding door.

[0011] Therefore, the electronic unit, along with the sensor unit, is protected, particularly on the outside of the electronic device, by a liner. This eliminates the need for a separate, complete housing for the electronic unit. Furthermore, the operating device can be inexpensively adjusted for any type of flat vehicle section. Thus, it is conceivable that the electronic unit is only mounted on the liner when installed in the vehicle section. This provides greater flexibility in the manufacturing of the operating device.

[0012] Furthermore, the operating device of the present invention can advantageously be configured such that the first housing portion has a filler or cover, particularly wherein the first housing portion is connected to the liner by a material bonding manner. In particular, the electronic unit and the liner can be directly infused together with the filler. The filler may, in particular, contain epoxy resin and / or acrylate to protect the electronic unit from environmental influences, particularly moisture. In particular, the filler can be transparent or opaque and / or light-proof. Material bonding between the first housing portion and the liner can be achieved by the filler. In particular, the inner and / or outer sides of the electronic device can be completely covered with the filler. Preferably, at least the sensor unit is completely covered with the filler. A seal can be achieved between the cover and the liner, particularly around the cover. The sealant may, for example, be silicone or a sealant. Furthermore, the sealant can simultaneously form a material bonding fixation of the cover to the liner. The first housing portion can be bonded, welded, and particularly friction welded and / or laser welded to the liner.

[0013] Furthermore, in the operating device according to the invention, it can be advantageously specified that the lining has an electronic device holder for accommodating an electronic unit, particularly wherein the electronic unit is fixed in the electronic device holder on the lining by a form-fit and / or material-joint manner. To form-fit the electronic unit in the electronic device holder, the shape of the electronic device holder can correspond to the shape of the electronic unit and / or the frame for the electronic unit. Preferably, the lining can be a cast part, particularly an injection-molded part. Thus, the electronic device holder can be formed in a simple manner on the inside of the lining. In particular, the electronic device holder can be integral with the inside and / or outside of the lining and be made of the same material. In particular, it can be specified that the electronic unit converges with the lining and / or the cover.

[0014] Preferably, the operating device of the present invention includes an electronic unit having a circuit board, preferably in the form of a circuit card, having at least one sensor element, particularly capacitive or inductive, for detecting (preferably non-contact) operational behavior, wherein the sensor element is arranged on the circuit board outside the electronic device. The circuit board forms the basis of the electronic unit. Preferably, the circuit board is a multilayer circuit board. The sensor element can be, in particular, a sensor electrode. For example, the sensor element may include an electric coil or a sensor surface in the form of a conductive surface. This allows the detection of capacitance or inductive changes in the electromagnetic field. Corresponding to the sensor element, a shield, particularly in the form of a shielding electrode, can be arranged inside the electronic device, thereby aligning the electric field of the sensor element. It is also conceivable that the sensor element is surrounded by a shield outside the electronic device, through which the electric field of the sensor element is aligned. It is also conceivable that the electronic unit has multiple circuit boards on which different electronic components are distributed.

[0015] Furthermore, it is advantageous to specify in the operating device of the present invention that the sensor unit has multiple, especially identical, sensor elements for detecting the operating action, thereby identifying the direction of the operating action. These sensor elements are preferably arranged on a circuit board outside the electronic device. For example, these sensor elements can be manufactured by printing and / or etching. The sensor element can be designed to be inductive and / or capacitive. Additionally or alternatively, it is conceivable that the sensor element is designed for optical detection and / or detection by means of ultrasound. The direction of the operating action can be detected along the arrangement direction of the sensor elements, especially outside the electronic device. Therefore, a gesture can be defined as the operating action. When the vehicle function is the opening of a sliding door, for example, a gesture along the opening direction of the sliding door can be defined as the operating action. Preferably, these sensor elements are arranged such that a horizontal gesture in front of the vehicle section causes the vehicle function to be triggered by the sensor unit.

[0016] Furthermore, in the operating device of the present invention, it is conceivable that the sensor elements are arranged on a circuit board in an ordered pattern, preferably in a matrix and / or strip form. The ordered pattern simplifies gesture recognition for identifying operational behaviors. A matrix arrangement can refer to a two-dimensional arrangement of the sensor elements. For example, particularly on the outside of an electronic device, 2×2 sensor elements can be arranged in a plane to form a minimal matrix arrangement. In the case of a strip arrangement, these sensor elements preferably have a long strip-shaped extension. In particular, the sensor elements are arranged side-by-side in a strip pattern in the case of a strip arrangement. Here, the distance between the sensor elements can be constant. Preferably, the sensor elements in the strip arrangement form a pattern on the circuit board that extends in only one direction. It is also conceivable that the sensor elements are arranged in an irregular pattern on the circuit board. By arranging the sensor elements in a pattern, any complex operational behavior in a plane can be detected. Furthermore, a structural unit can be implemented by arranging the sensor elements on a separate circuit board, which is easy to manipulate during manufacturing and provides a short signal path for detecting operational behaviors. The manufacturing of sensor elements using printing or etching methods can also be simplified.

[0017] In the operating device of the present invention, it is conceivable that the electronic unit has an indicator unit, thereby enabling the user to confirm the detection of an operating action and / or signal the start of an operating action on the outer side of the lining, particularly wherein the indicator unit is arranged on a circuit board. Through the indicator unit, an indication in signal form can be output to the user that the user can begin an operating action, and / or that the operating action has been detected by the sensor unit. Therefore, the indicator unit can be used, in particular, as a contactless user interface. The indication in signal form can be, for example, acoustic or optical. It is also conceivable that the indication in signal form can be, for example, in the form of a radio signal to the user's smartphone or electronic key. Preferably, the indicator unit is a one-way transmitting unit. In particular, user input can be made through the sensor unit. Therefore, the indicator unit and the sensor unit can form a dialogue unit for two-way communication with the user. By arranging the indicator unit on a circuit board that also houses the sensor element, the manufacturing of the operating device can be simplified, and the signal path of the electronic unit can be designed more concisely.

[0018] In the operating device of the present invention, it is also conceivable that the indicating unit is an optical indicating unit, and the lining has at least one light-transmitting window area through which optical signals can be transmitted to the user. The window area preferably includes one or more transparent portions. For example, the window area may include at least one recess in the lining material of the lining, which is closed by a light-transmitting material. This maintains the seal of the housing, and the indicating unit can be housed within the housing. The lining may be a two-component plastic injection molded part. Preferably, a transparent material can be sprayed into the opaque and / or opaque lining material of the lining within the window area. The entire lining may also be made of transparent material, wherein the opaque areas (non-window areas) are designed to absorb light or be opaque through films and / or paints and / or coatings.

[0019] Preferably, in the operating device of the present invention, the indicating unit may have multiple light-emitting elements for emitting optical signals to the user, particularly wherein these light-emitting elements are at least partially separated from each other by opaque partitions. Through the multiple light-emitting elements, more complex information as an indication can be transmitted to the user. For example, the indication that can be transmitted by the indicating unit may include direction, etc. In particular, the light-emitting elements can be dynamically controlled, thereby enabling a dynamic display process. The light-emitting elements may be light-emitting mechanisms, particularly in the form of LEDs. It is also conceivable that the indicating unit includes an LED display or an OLED display, and that the light-emitting elements are constituted by separate display elements. Through the display, display symbols of varying complexity can be shown to the user, so as to transmit information to the user about expected operating actions, confirmed operating actions, etc. In particular, the window may have multiple light-transmitting segments, which are separated from each other by partitions (particularly in the form of opaque and / or opaque material portions). The partitions can be designed to be integrated with or separate from the lining. For example, an intermediate element, particularly in the form of an insert, may be provided, which includes one or more partitions. The intermediate element may be made of, for example, Moos rubber or other flexible materials. Preferably, the intermediate component has a closed aperture. This allows the intermediate component to be designed to be non-absorbent. The partitions improve the visibility of the light source behind the liner from the outside. Preferably, the partitions can extend in a rib-like shape between the light-emitting elements. The partitions allow the light from the light-emitting elements to be directed in one direction, enabling the user to associate the light with one of the light-emitting elements, thus providing a clearer view of the dynamic changes when the light-emitting elements are dynamically activated. Preferably, an encapsulation space is formed around the light-emitting elements individually or in groups via the partitions. For this purpose, the partitions can form and / or seal the circuit board in a manner that surrounds the light-emitting elements. Thus, for example, the exterior of the electronic device can be covered by filling the gap between the electronic unit and the liner with filler, without obscuring the light-emitting elements with particularly opaque and / or light-blocking filler.

[0020] In the operating device of the present invention, it is also conceivable that the electronic unit is embedded in a frame by which it can be positioned on the backing. This frame allows for the formation of an adapter within the electronic device housing for the form-fitting of the circuit board. Preferably, the frame has a form-fitting member, particularly in the form of a locking member, for accommodating the circuit board. It is also conceivable that the electronic unit has multiple circuit boards arranged together within the frame and thus forming a common assembly. This simplifies the operation of mounting the electronic unit onto the backing. Therefore, the installer can grasp the frame while mounting the electronic unit onto the backing without touching the electronic components of the electronic unit. In particular, the frame is made of plastic.

[0021] Preferably, in the operating device of the present invention, the outer side of the electronic unit is covered with filler, particularly wherein the frame and / or electronic unit has at least one receiving member for a filling nozzle for filling the filler, so that the filler can be delivered from the inside of the electronic unit to the outside of the electronic unit while the electronic unit is placed on the liner. By filling the outer side of the electronic unit with filler, the gap between the electronic unit and the liner can be filled with filler. This prevents moisture from accumulating in the gap and thus adversely affecting the measurement of the sensor unit. The filler can be reliably applied to the outside of the electronic unit after the electronic unit is placed on the liner by means of the receiving member. The filling nozzle can refer to a tool or part of a tool for distributing filler. In particular, multiple receiving members for the filling nozzle can be arranged on the frame in a manner surrounding the circuit board of the electronic unit. This allows for reliable and uniform dispersion of the filler in the gap. Additionally or alternatively, it is conceivable to provide an elastic intermediary in the gap between the electronic unit and the liner. Preferably, the intermediary has a material with a closed hole. Furthermore, the intermediary can be elastically pre-tightened to the liner by the electronic unit. Therefore, gaps can also be filled through intermediate components to prevent moisture intrusion.

[0022] Advantageously, the operating device of the invention also includes an electronic unit having a touch sensor for detecting pressure applied to the trim, thereby triggering another function of the vehicle, particularly wherein the touch sensor includes an LDC sensor (inductive sensor). Another user operation can be achieved via the touch sensor. This other vehicle function could be, for example, locking and / or unlocking a lock. Additionally or alternatively, an emergency stop can be achieved via the touch sensor when a door automatically opens and / or closes. For example, a conductive target can be provided on the trim, and its distance change can be recorded via the touch sensor when the user presses the vehicle part and / or the trim. Preferably, multiple LDC sensors can be provided, particularly for verifying the detection of other operations and / or allowing such detection to be performed over a wider range of operations on the vehicle part and / or the trim. If, for example, it is stipulated that a function triggered by the sensor unit is only permitted after another function is activated, the probability of false triggering can be significantly reduced.

[0023] Furthermore, the operating device of the present invention can advantageously include an authentication mechanism for user identification, particularly wherein the authentication mechanism has a radio component for contactless data exchange with an ID transmitter. The ID transmitter may, for example, refer to the user's smartphone and / or electronic key. The authentication mechanism may, in particular, include an NFC (Near Field Communication) interface, a BLE (Bluetooth Low Energy) interface, and / or a UWB (Ultra-Wideband) interface. User authentication can thus be achieved through the authentication mechanism. In particular, the authentication mechanism can communicate with the vehicle control unit for user authentication. Specifically, identity verification can be performed by the vehicle control unit based on the data exchange between the authentication mechanism and the ID transmitter.

[0024] Preferably, the operating device of the present invention includes an electronic unit having a proximity sensor for recognizing a user's approach, particularly wherein the proximity sensor is designed for capacitive detection of the approach. Therefore, in addition to the sensor unit, a separate capacitive sensor may also be provided, in particular, via the proximity sensor. When a user's approach is recognized, the proximity sensor can, for example, activate the sensor unit, the touch sensor, and / or the authentication mechanism. This saves energy during operation of the operating device. Furthermore, the proximity sensor can activate the indication unit upon detecting an approach. For example, this can send a signal to the user indicating the activation status of the operating device.

[0025] Furthermore, in the operating device of the present invention, the circuit board can advantageously be configured to have multiple conductive layers, wherein the sensor unit is arranged on a first conductive layer, and the touch sensor and / or identification mechanism is arranged on a second conductive layer. Here, the conductive layers can be electrically isolated from each other. In particular, a sensor plane can be formed through each of the conductive layers. This allows for a compact design of the circuit board and / or electronic units.

[0026] Furthermore, in the operating device of the present invention, the electronic unit can advantageously be configured to have a control unit for evaluating the sensor signal of the sensor unit and controlling the indication unit based on the sensor signal. For example, the sensor signal of the sensor unit can be digitized and forwarded directly in the electronic unit via the control unit. It is also conceivable that the direction of the operating action can be identified by the control unit based on the evaluation of the sensor signal. By evaluating the sensor signal within the electronic unit, a short signal path can be achieved. In addition, the indication unit can be controlled based on the sensor signal, thereby providing the user with feedback regarding the measured direction of the operating action.

[0027] According to another aspect of the invention, a vehicle is provided. The vehicle has an operating device for user-initiated vehicle functions, particularly an operating device according to the invention. The operating device includes a flat liner of the vehicle portion having an inner liner side and an outer liner side. The operating device also includes an electronic unit with a sensor unit for detecting user operation that initiates vehicle functions. The electronic unit has an outer electronic device side and an inner electronic device side, wherein the inner electronic device side faces the outer electronic device side. Furthermore, the electronic unit is oriented with the outer electronic device side facing the inner liner side and is mounted on the liner to detect operation on the outer liner side. Additionally, a first housing portion for protecting the inner electronic device side is fixed to the liner such that the liner and the first housing portion form a complete housing to protect the electronic unit.

[0028] Therefore, the vehicle of the present invention provides the same advantages as explicitly described regarding the operating device of the present invention. The vehicle is preferably a motor vehicle. Preferably, the vehicle portion also includes the vehicle's B-pillar and / or interior components. Functions that can be triggered by the operating device may include automatic movement of the vehicle portion. When the lining is an exterior lining, the inner side of the electronic device can be oriented, for example, in the direction of the vehicle's interior, while the outer side of the electronic device can be oriented in the direction of the vehicle's exterior. Additionally, when the lining is an interior lining, the inner side of the electronic device can be oriented, for example, in the direction of the vehicle's exterior, while the outer side of the electronic device is oriented in the direction of the vehicle's interior.

[0029] Therefore, the electronic unit, along with the sensor unit, is protected by the liner, allowing the operating device to be installed on the vehicle component in a cost-effective manner. Furthermore, since the electronic unit is only mounted on the liner when installed on the vehicle component, the design freedom of the liner can be increased. This also provides greater overall flexibility in the manufacturing of the operating device.

[0030] Furthermore, in the vehicle of the present invention, it is advantageous to specify that the vehicle part is a door, particularly in the form of a sliding door, wherein an opening mechanism is provided for automatically opening the door according to the operation. Thus, the operating device can also move with the door when it is opened, thereby providing intuitive operation for the user when the operation can be performed directly on the open or closed door. In particular, the vehicle part can be designed to be handle-less.

[0031] According to another aspect of the present invention, a method is provided for manufacturing an operating device for activating functions of a vehicle, particularly a vehicle of the present invention, by a user, comprising the following steps:

[0032] - Provides flat lining pieces for vehicle parts, having an inner lining side and an outer lining side.

[0033] - Provides an electronic unit having a sensor unit for detecting user actions that trigger vehicle functions.

[0034] - The electronic unit is mounted on the lining such that the outer side of the electronic device of the electronic unit faces the inner side of the lining.

[0035] - A first housing portion for protecting the inner side of the electronic device is fixed to the lining, such that the lining and the first housing portion form a complete housing for protecting the electronic unit.

[0036] Therefore, the method of the present invention provides the same advantages as those explicitly described regarding the operating device and / or the vehicle of the present invention. Preferably, the flat liner is manufactured as a casting, particularly a multi-component plastic injection molded part, when the liner is provided. When the electronic unit is provided, the circuit board can mount (print) the electronic components. Additionally or alternatively, the electronic components can be etched when the electronic unit is provided. When the first housing portion is fixed to the liner, a material bonding connection between the first housing portion and the liner can be achieved. Thus, the electronic unit, together with the sensor unit, is protected by the liner, thereby allowing the operating device to be installed in the vehicle in a cost-effective manner.

[0037] Preferably, in the method of the present invention, the first housing portion is formed by filler, which is then filled together with the electronic unit and the liner. This allows for a simple material bonding connection between the first housing portion and the liner. In particular, the filler can be used to cover both the inner and outer sides of the electronic device during the filling process. Preferably, the gap between the liner and the electronic unit is completely or substantially completely filled with filler. This prevents moisture from entering the measurement field area of ​​the sensor unit, thereby improving the reliable operation of the sensor unit. Attached Figure Description

[0045] Figure 9 and Figure 10 The electronic unit of the operating device is shown in another embodiment.

[0046] Figure 11-13 The different conductive layers of the circuit board of the electronic unit are shown. Detailed Implementation

[0047] In the following description of several embodiments of the present invention, the same reference numerals are used for the same technical features even in different embodiments.

[0048] Figure 1 The vehicle 1 of the present invention shown in the first embodiment has a vehicle section 2 specifically designed as a sliding door. Here, the vehicle 1 also has an operating device 10 for initiating functions of the vehicle 1. The operating device 10, as exemplarily shown, can be mounted on the B-pillar 2.1 of the vehicle 1 and / or, particularly, on the vehicle section 2, which is a door or sliding door. The function may, for example, be automatically opening and / or closing the sliding door. Here, the function is particularly based on the user's operating action 200. For example, the opening of the vehicle section 2 can be initiated by an operating action 200 in the form of a gesture in the opening direction of the vehicle section 2, or the closing of the vehicle section 2 can be initiated by an operating action 200 in the form of a gesture in the opposite direction of opening.

[0049] like Figure 2 As shown, the operating device 10 has a flat trim piece 11 for the vehicle part 2. The flat design of the trim piece 11 may extend, for example, along a portion of the vehicle body 1 or behind the window glass of the vehicle part 2. The trim piece 11 includes a trim outer side 11.2 and a trim inner side 11.1. The trim outer side 11.2 preferably forms part of the surface of the vehicle part 2 and / or the surface 1.1 of the vehicle body 1.1 visible from outside the vehicle 1. For example, the trim piece 11 may be part of the trim in the area of ​​the B-pillar 2.1 of the vehicle 1. An electronic unit 12 is arranged directly on the trim piece 11, having an electronic device outer side 12.2 and an electronic device inner side 12.1. Here, the electronic device outer side 12.2 is oriented toward the trim inner side 11.1 of the trim piece 11. The electronic device inner side 11.1 is opposite to the electronic device outer side 11.2. In particular, the electronic device inner side 11.1 is oriented toward the vehicle interior of the vehicle 1 and / or the trim cavity of the vehicle part 2. However, it is also conceivable that the trim piece 11 is part of the interior of the vehicle 1. In this case, the inner side 12.1 of the electronic device may, for example, be oriented towards the outer side of the vehicle 1.

[0050] Additionally, the electronic unit 12 has a sensor unit 20 for measuring the user's operational behavior 200. The sensor unit 20 is preferably arranged on the outer side 12.2 of the electronic device of the electronic unit 12, specifically such that only the lining 11 is arranged between the sensor unit 20 and the outer side 11.2. By arranging the electronic unit 12 on the inner side 11.1 of the lining 11, the outer side 12.2 of the electronic device is protected by the lining 11. To protect the inner side 12.1 of the electronic device, the operating device 10 also has a first housing portion 31, which is indirectly or directly fixed to the lining 11, such that the lining 11 and the first housing portion 31 form a closed housing 30. Possible designs for the housing 30 are described in... Figure 3 and Figure 4 The example shown is illustrated in the text.

[0051] Figure 3 The housing 30 is shown, where the first housing portion 31 is formed by filler 31.1. The circuit board 13 of the electronic unit 12 is also embedded in a frame 14, through which the electronic unit 12 is better operated during installation and / or the electronic unit 12 can be fixed to the liner 11 in a form-fitting manner. Here, the filler 31.1 is connected to the liner 11 by material bonding and preferably completely covers the inner side 12.1 of the electronic device. In particular, the outer side 12.2 of the electronic device is also at least partially or completely covered by the filler 31.1, such that at least the sensor unit 20 is covered by the filler 31.1. Preferably, the sensor unit 20, the electronic unit 12, and / or the housing 30 are at least partially symmetrical about the central plane 10.1, so that the operating device 10 can be selectively installed on opposite sides of the vehicle.

[0052] Additionally, the electronic unit 12 has an indicator unit 40, which can confirm the detection of operation 200 and / or signal the start of operation 200 to the user on the outer side of the lining 11.2. The indicator unit 40 includes a plurality of light-emitting elements 42 for emitting optical signals to the user. The light-emitting elements 42 may be, in particular, light-emitting mechanisms in the form of LEDs. The light-emitting elements 42 are arranged in a row and separated by a separator 43. By arranging the light-emitting elements 42 in a serial manner, the direction of operation 200 detected by the sensor unit 20 can be displayed to the user, for example, by activating the light-emitting elements 42 in a serial order. The separator 43 may be formed by an intermediate element 43.1, which is arranged between the lining 11 and the electronic unit 12. In particular, the separator 43 is designed to be opaque and / or light-blocking so that the light emitted by the light-emitting elements 42 can be individually guided to the outer side of the lining 11.2 for each light-emitting element 42. Preferably, the intermediate element 43.1 may also be elastically configured and pre-tightened to the circuit board 13 of the electronic unit 12. Thus, each light-emitting element 42 can be particularly circumferentially encapsulated, so that when the electronic unit 12 is filled with filler 31.1, the light-emitting element 42 remains without filler 31.1. Additionally, the liner 11 has a light-transmitting window area 41 through which the optical signal of the indicating unit 40 can be transmitted to the user. For example, the window area 41 can have a transparent window material 41.1, especially transparent plastic. The transparent window material 41.1 can be sprayed onto the opaque and / or opaque base material of the liner 11, for example, as a plastic injection molding component during the manufacture of the liner 11.

[0053] Alternatively or additionally, the light-emitting element 42 may also be part of a display or the like. It is also conceivable that the indicator unit 40 can output acoustic indications or indications in the form of radio signals to the user. It is also conceivable that the separator 43 is formed by the lining element 11. For example... Figure 4 As shown, the separator 43 can be designed to be integrated with the lining 11. Here, the separator 43 preferably extends into the circuit board 13 in a rib-like shape.

[0054] Figure 4 A housing 30 is also shown, wherein the first housing portion 31 is formed by a cover 31.2, which is particularly rigid. The cover 31.2 may be made of, for example, a hard plastic, and is placed together with the electronic unit 12 when the operating device 10 is mounted to the liner 11. Here, the seal between the cover 31.2 and the liner 11 can be advantageously achieved by a sealant 33, in particular, surrounding the cover 31.2. The sealant 33 may be made of, for example, silicone. Furthermore, the sealant 33 can simultaneously form a material bond and fix the cover 31.2 to the liner 11.

[0055] Figure 5Another exploded view of the operating device 10 is shown. Here, the lining 11 has an electronic device housing 15 for receiving the electronic unit 12 in a form-fitting manner, particularly with the frame 14. Additionally, an electrical connector 35 may be provided, thereby allowing the electronic unit 12 to be connected to or connected to vehicle electronics and / or the vehicle power supply. For this purpose, the electrical connector 35 can extend from the housing 30. In particular, the electrical connector 35 can be potted with sealant 33 and / or filler 31.1.

[0056] Figure 6 A method 100 for manufacturing an operating device 10 is illustrated with a schematic diagram of the steps. The method includes: step one 101, providing a lining 11, and step two 102, providing an electronic unit 12. In step one 101, the lining 11 can be manufactured, for example, by plastic injection molding and / or removed from a support. In step two 102, the electronic unit 12 can be provided, with sensor unit 20 and / or other electronic components arranged on a circuit board 13 of the electronic unit 12, particularly by printing and / or etching. Next, in step three 103, the electronic unit 12 is arranged on the lining 11, such that the outer side 12.2 of the electronic unit 12 is oriented towards the inner side 11.1 of the lining 11. In particular, the electronic unit 12 can be fixed within a frame 14 by form-fitting and / or force-fitting, by means of which the electronic unit 12 is placed on the lining 11, particularly on the electronic device housing 15. The method 100 further includes: step four 104, fixing the first housing portion 31 to the lining member 11, thereby forming a complete housing 30 with the lining member 11 and the first housing portion 31. For example, when the first housing portion 31 is as follows... Figure 3 When constructed using filler 31.1 as shown, the electronic unit 12 can be cast together with the lining 11. Additionally or alternatively, when fixing the first housing portion 31 in step four 104, an application such as... Figure 4 The sealant 33 shown.

[0057] Figure 7 and Figure 8 An electronic unit 12 for operating the device 10 is shown in one possible embodiment. Here, the circuit board 13 of the electronic unit 12 is arranged within a frame 14, which simplifies its fixation to the lining 11. For this purpose, the frame 14 has a locking member 14.1 in which the circuit board 13 can be clamped. Furthermore, the frame 14 preferably has one or more receiving members 14.2 for filling nozzles for filling filler 31.1, thereby advantageously allowing the filler 31.1 to be distributed from the inner side 12.1 of the electronic device to the outer side 12.2 of the electronic device. Figure 7 The electronic unit 12 is shown here from the inside 12.1 of the electronic device. Figure 8The electronic unit 12 is shown from the outer side 12.2 of the electronic device, opposite the inner side 12.1. On the outer side 12.2, a plurality of sensor elements 21 of the sensor unit 20 are arranged in a matrix on the circuit board 13 according to an ordered pattern. Here, each of the sensor elements 21 forms a capacitance region. The sensor unit 20 is therefore, in particular, a capacitive sensor, thereby enabling the identification of non-contact operation 200. The matrix arrangement of the sensor elements 21 also allows for the identification of the direction of the operation 200. Thus, for example, when a user touches the outer side 11.2 of the lining 11, the electric field within the sensor elements 21 changes sequentially according to the direction of the operation 200. Based on the detection sequence using the sensor elements 21, the direction of the operation 200 can be inferred. For this purpose, the electronic unit 12 preferably has a control unit 25 for evaluating the sensor signals of the sensor unit 20. Furthermore, the control unit 25 can control the indicator unit 40 to, for example, display to the user the detection of the operation 200 and / or the direction of the operation 200. Corresponding to the sensor element 21, shielding members 21.1 are arranged in a matrix on the inner side 12.1 of the electronic device for shielding the sensor element 21. In particular, each of the sensor elements 21 is assigned an opposing shielding member 21.1.

[0058] Figure 9 and Figure 10 An electronic unit 12 for operating the device 10 is shown in another possible embodiment. Here, the electronic unit 12 substantially corresponds to... Figure 7 and Figure 8 The embodiment of the electronic unit 12, however, includes a sensor unit 20 in which the sensor elements 21 are arranged in a strip shape. Even when arranged in a matrix, multiple directions of the operation 200 can be detected, and the direction of the operation 200 can be measured along a straight line in the case of the strip-shaped sensor elements 21. However, by arranging the sensor elements 21 in a strip shape, a larger capacitive field is obtained in the same structural space, thereby reducing false recognition. Inside the electronic device 12.1, corresponding to the strip shape of the sensor elements 21, a shield 21.1 is arranged in a strip shape and corresponding to the sensor elements 21.

[0059] In addition to sensor unit 20, electronic unit 12 preferably also includes touch sensor 22, authentication mechanism 23 and / or proximity sensor 24, such as Figure 11-13As shown. The authentication mechanism 23 may include, in particular, a radio component 23.1 in the form of an electric coil, which may be printed on the circuit board 13 as a loop conductor rail. Contactless data exchange with the user's ID transmitter can be achieved through the authentication mechanism 23. Therefore, the authentication mechanism 23 preferably includes an NFC interface, a BLE interface, and / or a UWB interface. This allows for user authentication and / or verification, especially through vehicle electronics that enable data communication between the authentication mechanism 23 and the vehicle. Based on the user authentication by the authentication mechanism 23, automatic locking and / or unlocking of the vehicle 1 can be specified. The touch sensor 22 may include, for example, an LDC sensor, which can detect deformation caused by touching or pressing the lining 11. Based on the operation of the touch sensor 22, another function of the vehicle 1, such as the automatic opening and / or closing movement of the vehicle section 2 or an emergency stop during the movement of the vehicle section 2, may be triggered. A wake-up signal for other electronic components may be allowed, for example, based on the recognition of the user's proximity, through, particularly an additional proximity sensor 24. Preferably, the touch sensor 22, the authentication mechanism 23, and / or the proximity sensor 24 are arranged within different conductive layers 13.1, 13.2 on the circuit board 13. Here, for example, it can be determined according to... Figure 11 The sensor unit 20 and the authentication mechanism 23 are jointly arranged on the first conductive layer 13.1. The touch sensor 22 and the proximity sensor 24 can also be arranged on the second conductive layer 13.2 of the circuit board 13, respectively. Through the multi-layer design of the circuit board 13, a compact design structure can be obtained, and the circuit board 13 can thus be advantageously placed on the backing member 11 with a small structural space. Therefore, the touch sensor 22, the authentication mechanism 23 and / or the proximity sensor 24 can provide the user with a high degree of automation and comfortable operation possibilities through the operating device 10.
