UWB Actuation System for a Moving Part of a Vehicle

Description

[0001] The present invention relates to an actuation system for a movable part, in particular a door or a flap, of a vehicle, preferably in the form of an access system to a vehicle interior, a functional space, or a functional element of the vehicle. Furthermore, the present invention relates to a corresponding vehicle with at least one such actuation system. The invention also relates to a method for actuating a movable part, in particular a door or a flap, of a vehicle using such an actuation system.

[0002] Actuation systems for moving parts of vehicles, such as doors or hatches, are generally known, as exemplified by US 2015 / 161836 A. Modern actuation systems can also be designed to detect specific movements of the user or a body part (a foot or hand) and trigger corresponding actions, such as contactless opening of the door or hatch. These modern systems require complex sensor units as well as evaluation and control electronics. Some vehicle models are offered in different versions and / or equipment packages, some of which can support such actuation systems. This increases the cost for some models, while other models cannot offer this advantageous functionality.

[0003] The object of this application is therefore to provide an improved actuation system for a moving part, in particular a door or a flap, of a vehicle, which is simple and cost-effective, which has improved functionality, and which enables improved, user-friendly, convenient, and intuitive actuation of the moving part. In particular, the object of this application is to provide an improved actuation system for a moving part, in particular a door or a flap, of a vehicle, which allows for flexible, upgradable versioning, and which decouples the improved functionality of the actuation system, at least in part, from the vehicle's sensor units and evaluation and control electronics.Furthermore, the object of the invention is to provide a corresponding vehicle and an improved method for actuating a movable part, in particular a door or a flap, of a vehicle.

[0004] The foregoing problem is solved by an actuation system for a movable part, in particular a door or a flap, of a vehicle, preferably in the form of an access system to a vehicle interior, a functional space, or a functional element of the vehicle, comprising the features of the independent device claim; by a corresponding vehicle with at least one such actuation system comprising the features of the dependent independent device claim; and by a method for actuating a movable part, in particular a door or a flap, of a vehicle using such an actuation system comprising 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 actuation system according to the invention naturally also apply in connection with the vehicle according to the invention and the method according to the invention, and vice versa, so that with regard to the disclosure of the individual aspects of the invention, mutual reference is always made or can be made.

[0005] The problem is solved in particular by an actuation system for a movable part, especially a door or a flap (e.g., fuel filler flap, charging flap, tailgate), of a vehicle, preferably in the form of an access system to a vehicle interior (e.g., passenger compartment), a functional space (e.g., trunk), or a functional element (e.g., refueling port or charging plug) of the vehicle, comprising at least one UWB sensor unit, wherein the UWB sensor unit is designed to perform detection (i.e., acquisition with only one device) of a user's movement pattern, in particular of a body part, preferably a foot or hand, and wherein the UWB sensor unit is designed to perform communication (i.e.,a data exchange between two devices) is carried out with a user-side mobile device in order to transmit at least one result of the detection and / or communication to the vehicle-side control unit and to actuate the moving part depending on the result.

[0006] UWB stands for Ultra-Wideband technology. The UWB sensor unit can include a UWB transceiver, for example, in the form of a UWB front-end module. The UWB sensor unit can also include a processing device, for example, an electronic processing arrangement, which may utilize a microcontroller for processing. The processing device can control the UWB transceiver and process the electrical signals sent and / or received by the UWB transceiver in order to evaluate the communication and / or detection and obtain a result or information based on the communication and / or detection.The processing device can also generate a function code for actuating (including actuating functions such as: opening, closing, unlocking, locking) the moving part, based on, in particular depending on, the evaluation, communication and / or detection, in order to trigger a corresponding actuating function.

[0007] The UWB sensor unit can have an interface, e.g. in the form of an electronic interface, which can connect the UWB sensor unit electrically, control-wise and data-wise to the vehicle's control unit or directly to a locking system of the moving part, in order to, for example, transmit the results of the communication and / or the detection to the control unit via the interface and / or to trigger at least one corresponding actuation function for actuating the moving part depending on the communication and / or the detection.

[0008] The electrical signals transmitted and / or received by the UWB transceiver of the UWB sensor unit can be specific for communication and / or detection. This means, in particular, that the processing device can determine the result of the detection and / or communication based on the electrical signals.

[0009] A detection result can include at least information about whether a user or person and / or object is near the UWB sensor unit, is approaching the UWB sensor unit, is moving and / or is moving in a particular way.

[0010] The result of communication between the UWB sensor unit and the user's mobile device can include at least one piece of information about the user, e.g., authentication information, to ensure that only an authorized user can operate the moving part.

[0011] Via the interface, the UWB sensor unit can transmit information about the user, e.g. authentication information, the results of communication and / or detection, and the function code calculated in particular by the processing device for a corresponding function code to actuate the moving part to the vehicle's control unit or directly to a locking system of the moving part.

[0012] The result of communication between the UWB sensor unit and the user's mobile device can also include navigation data, message data, music data, and the like. For security reasons, the user must first authenticate themselves to prevent the exchange of unauthorized data between the UWB sensor unit and the user's mobile device. This data can also be transmitted from the UWB sensor unit to the vehicle's control unit via the interface.

[0013] A signal for communication can be, for example, a defined sequence of short UWB pulses. This defined sequence of short UWB pulses, which can be time-stamped, for instance, can be generated using pulse-phase modulation within a digital radio transmission. In this process, a UWB pulse is shifted in phase relative to a constant reference clock. The phase shift between the UWB pulses symbolizes the information, such as authentication information. The period and amplitude remain constant.

[0014] A UWB pulse can be represented, for example, as part of a sinusoidal oscillation of a limited duration of a few nanoseconds or even picoseconds, corresponding to a broad spectral line of at least 5 GHz, in particular 7.5 GHz, up to over 8.8 GHz.

[0015] Due to the extremely short UWB pulses, a high transmission rate of 480 to 1320 Mbit / s can be achieved in communication, e.g. using digital radio transmission.

[0016] Also due to the extremely short UWB pulses, a high resolution of a few millimeters to even micrometers can be achieved in detection, e.g. by measuring the time of flight of the UWB pulses, which can be time-stamped, for example.

[0017] The dimensions of the UWB antenna of the UWB sensor unit determine the center frequency and bandwidth of the UWB pulse. The total transmit power of the UWB antenna, amounting to just a few milliwatts (e.g., approximately 0.5 mW), is distributed over such a wide frequency range that it causes virtually no interference with narrowband radio transmission methods.

[0018] The inventive concept lies in the fact that the UWB sensor unit uses UWB technology to perform communication, i.e., data exchange between two devices, and / or detection, i.e., the recording of motion patterns, with only one device, namely the UWB sensor unit. The UWB antenna for communication and detection can comprise a single UWB antenna unit or two separate UWB antenna units, allowing communication and detection to be performed simultaneously or sequentially.

[0019] The invention also lies in the fact that the UWB sensor unit enables high-resolution detection with a resolution of a few millimeters to even micrometers, for example, by measuring the time of flight of the UWB pulses. This allows for the provision of an actuation system that operates reliably and significantly increases safety when actuating the moving part. The actuation system can include one or more UWB sensor units to provide 2D or 3D resolution. Furthermore, the use of multiple UWB sensor units enables the rapid and high-resolution detection and analysis of complex movements.

[0020] A further advantage of the invention lies in the fact that detection and communication using a UWB sensor unit has a limited range, e.g., 10–50 m. This effectively prevents erroneous activation or manipulation of the moving part. In particular, so-called man-in-the-middle attacks can be virtually eliminated with the invention. During communication, information such as authentication data is transmitted only over this limited range. If the UWB sensor unit detects that no user can identify themselves within this limited range, access to the vehicle is reliably denied. Unauthorized extensions of the communication can thus be virtually ruled out.

[0021] A corresponding user-owned mobile device can also be part of the operating system according to the invention. The mobile device can be an electronic device that the user can carry with them. Ideally, it is an ID transmitter that can be designed to be active (by pressing a button) or passive (without pressing a button), thus forming a so-called active keyless entry system or a passive keyless entry system with the vehicle's security device. The mobile device can also be a mobile phone, in particular a smartphone, or a tablet or smartwatch, in order to achieve the desired data exchange by communicating with the UWB sensor unit. In addition to communication for the identification process with the corresponding identification code, other (triggered) functions can also be triggered or controlled by the mobile device on the vehicle. For example,The vehicle's interior or exterior lighting, warning signals, and similar functions can be controlled via the mobile device (e.g., arming and disarming the alarm system, closing windows, turning on the heating, etc.). Data transmission between the vehicle and the mobile device is also possible, including navigation, music, video, and / or message data.

[0022] Advantageously, the actuation system can be designed to detect a 2D motion pattern or a 3D motion pattern.

[0023] Furthermore, it can be advantageous for the actuation system to be configured to detect a first movement sequence, particularly in a first direction, which serves to open the movable part. It can also be advantageous for the actuation system to be configured to detect a second movement sequence, particularly in a second direction, preferably opposite to the first, which serves to close the movable part. Finally, it can be advantageous for the actuation system to be configured to detect a third movement sequence, particularly in the form of a, preferably single or double, tapping motion or a rotary motion in a first direction, which serves to unlock the movable part.Furthermore, it may be advantageous for the actuation system to be designed to detect a fourth movement sequence, in particular in the form of a, preferably simple or double, tapping movement or a rotational movement in a second direction of rotation, which is preferably opposite to the first direction of rotation, which serves to effect a locking of the movable part.

[0024] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit is designed as a single, in particular combined, individually manageable and / or interconnected module unit, preferably a multifunctional unit, preferably in the form of a hardware unit, for providing different actuation functions of the moving part. Thus, the UWB sensor unit can be provided as a single node, or in other words, as a satellite, which is provided as a single interconnected hardware unit with all necessary sensor functions (communication and detection), processing and control components, as well as an interface to the vehicle's control unit, in order to provide different functions (motion pattern detection and authentication) using only one UWB sensor unit.A single UWB antenna (which can comprise multiple UWB antenna units) can provide all the necessary sensor functions for the various applications. This allows for the advantageous provision of a simple, cost-effective, easily mounted, and easily connected (electrically, control-wise, and data-wise) actuator system. Furthermore, such an actuator system, or rather its UWB sensor unit, can be integrated with its own processing device within a single housing element, simplifying its handling as a single, manageable module. The UWB sensor unit of such an actuator system, in conjunction with the processing device, can provide a complete control unit for actuating the moving part. The processing device can generate all the necessary control commands for this actuation.In an actuation system for a tailgate, the UWB sensor unit can be provided as a kick sensor module.

[0025] Furthermore, the invention can provide for an actuation system in which one or more UWB sensor units are provided for a moving part. Multiple UWB sensor units can assist in detection for motion pattern recognition, providing high 2D or 3D resolution. With the aid of multiple UWB sensor units, complex movements can also be detected very quickly and with high resolution.

[0026] Furthermore, the invention can provide, in an actuation system, that one or more UWB sensor units are arranged, in particular on the inside, on a rear area, on a bumper, on a diffuser, on a structural component, on an A-, B-, and / or C-pillar, a side area and / or on the moving part. In this way, different functions can be provided for different moving parts of the vehicle.

[0027] Within the scope of the invention, it is conceivable that the user is informed of the activation via the user's mobile device and / or the vehicle's control unit. Advantageously, the mobile device can inform the user of the activation through haptic signals, e.g., vibration, acoustic signals, or visual displays. The vehicle's control unit, in turn, can control certain visual displays on the vehicle, such as lights, to inform the user of the activation. Different activation functions can be signaled, for example, using different colors, such as green for opening, red for closing, blue for unlocking, and / or yellow for locking.

[0028] Furthermore, the invention may provide, in an actuation system, that the UWB sensor unit has at least one printed circuit board, wherein in particular at least one of the following elements is arranged on the printed circuit board: a UWB antenna for carrying out communication and / or detection, wherein different actuation functions (such as e.g.: opening, closing, unlocking, locking) to actuate the moving part, a UWB transceiver, in particular electronic, for transmitting and / or receiving electrical signals from the UWB antenna, which are specific for communication and / or detection, a processing device, in particular electronic, for controlling the UWB transceiver in order to carry out communication and / or detection by the UWB antenna, and / or an interface, in particular electronic, for transmitting a result of the communication and / or detection to the vehicle control unit or directly to the moving part in order to initiate actuation functions for actuating the moving part depending on the communication and / or detection.In this way, the UWB sensor unit can be provided as a modular unit, preferably a multifunctional unit, preferably in the form of a hardware unit, which can be handled individually and / or as a single, combined, and / or interconnected module for providing different actuation functions in a vehicle.

[0029] Furthermore, the invention can provide, in an actuation system, that the UWB antenna is operable in a frequency range with a bandwidth of at least 500 MHz or at least 20% of the arithmetic mean of the lower and upper cutoff frequencies of the frequency band used, wherein the frequency range is preferably between 30 MHz and 10.6 GHz, more preferably between 3.0 and 10.6 GHz. In this way, communication and / or detection using UWB technology can be provided.

[0030] Furthermore, the invention can provide, in an actuation system, that the UWB antenna comprises one, and in particular only one, preferably a common UWB antenna unit for communication and / or detection, which is configured to perform communication and / or detection depending on a control signal from the processing device. Using only one UWB antenna unit, communication and detection can be performed sequentially or alternately. In turn, only one UWB antenna unit can have a simple and compact design.

[0031] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB antenna, comprises a first UWB antenna unit and a second UWB antenna unit, wherein the first UWB antenna unit is configured to perform detection, and wherein the second UWB antenna unit is configured to perform communication. Using different UWB antenna units, communication and detection can be performed either simultaneously or sequentially. By using different UWB antenna units for communication and detection, the UWB antenna units can be specifically designed for performing either communication or detection. In this way, communication and detection can be performed with increased accuracy.

[0032] Furthermore, the invention can provide that, in an actuation system, the UWB antenna is manufactured on the printed circuit board using a photolithographic process. In this way, the UWB antenna can be manufactured in a single manufacturing process with the printed circuit board, which can simplify the production of the UWB sensor unit. This also allows for a simple and compact UWB sensor unit.

[0033] Furthermore, the invention can provide for an actuation system in which the processing device and / or the UWB transceiver includes a microcontroller. This allows for the provision of programmable electronic components for operating and / or controlling the UWB antenna with memory. Thus, the UWB sensor unit can be programmed according to the user's wishes to detect specific movement patterns as activation actions for the moving part. Moreover, this allows the UWB sensor unit, including its range, detection areas, etc., to be adapted to the conditions and weather at the installation site.

[0034] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB transceiver, comprises at least one first UWB front-end module for a first UWB antenna unit and a second UWB front-end module for a second UWB antenna unit. In this way, the first UWB antenna unit and the second UWB antenna unit can be operated simultaneously, thus enabling greater flexibility and customer convenience in providing actuation functions via the UWB sensor unit.

[0035] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB transceiver, is designed as a common UWB front-end module for a first UWB antenna unit and a second UWB antenna unit. In this way, the first UWB antenna unit and the second UWB antenna unit can be operated alternately. Thus, communication and detection can be carried out separately, for example to avoid interference.

[0036] Advantageously, the invention can provide in an actuation system that the UWB sensor unit, in particular the UWB transceiver, has a switching unit to control a first UWB antenna unit and a second UWB antenna unit for carrying out communication or for carrying out detection. Thus, switching between communication and detection can be done in a simple manner.

[0037] Furthermore, it is conceivable that the switching unit could be designed as an electronic switch, preferably an RF switch. In this way, the UWB sensor unit can switch between communication and detection at high frequency during operation, enabling fast, reliable, and convenient provision of actuation functions.

[0038] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB transceiver, is designed such that the medium frequency and / or the bandwidth of the UWB antenna are variably adjustable during detection. In this way, it is possible to flexibly adapt the detection by the UWB antenna to different environmental influences, preferably humidity levels.

[0039] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB transceiver, is designed such that measurements taken by the UWB antenna during detection can be calibrated using measurements taken by the UWB antenna, in particular the transit times of the UWB pulses, during communication. In this way, the transit times of the signals between the UWB sensor unit and a mobile device positioned at a known distance from the UWB sensor unit can be measured. These transit times can be used to refine the accuracy of the detection by the UWB antenna, for example, during distance measurement, and thus to calibrate the UWB antenna for detection. Advantageously, this can significantly increase the accuracy of the detection by the UWB antenna. Calibrating the UWB antenna for detection can be performed by a user.Advantageously, it is also conceivable that the calibration of the UWB antenna for carrying out the detection can be performed independently and unnoticed by a user, e.g. in typical recurring situations due to user habits, if the distance of the user's mobile device to the UWB sensor unit is known.

[0040] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the UWB transceiver, is designed such that the angle of incidence of the UWB antenna is variably adjustable. This allows measurement ranges for performing detection to be advantageously set and / or aligned. Consequently, motion pattern recognition can be performed very accurately using this detection method. Even complex motion patterns can be reliably detected.

[0041] An actuation system within the scope of the invention can provide that the UWB sensor unit, in particular the UWB transceiver, is designed to perform the detection in order to: a presence of a user or person and / or object, a distance to a user and / or object, a position of a user and / or object, and / or an approach of a user and / or object, a specific sequence of movements by a hand or foot of the user.

[0042] In this way, the UWB sensor unit can be used in a variety of ways to actuate different moving parts and / or support various vehicle assistance systems.

[0043] An actuation system within the scope of the invention can further provide that the UWB sensor unit, in particular the UWB transceiver, is designed to serve as a detection unit, preferably by evaluating the transit time of UWB pulses, in particular as one of the following detection units: Proximity sensor, motion sensor, and / or motion pattern recognition sensor.

[0044] In this way, beneficial vehicle functions can be provided in an improved manner for the vehicle's external monitoring using the UWB sensor unit.

[0045] Advantageously, the UWB sensor unit, in particular the UWB transceiver, can be configured to perform communication, especially via digital radio transmission, preferably using pulse-phase modulation, in order to query, receive, and / or verify information, in particular user authentication information, from the user's mobile device. This allows the user's authorization to be verified. Consequently, the operational safety of the control system can be increased, ensuring that only an authorized user can operate the moving part.

[0046] Furthermore, it can be advantageous for the UWB sensor unit, particularly the UWB transceiver, to be designed to transmit the results of the communication and / or detection to the user's mobile device. This allows the user to verify the accuracy of the actuation, thereby increasing confidence in the actuation system.

[0047] Furthermore, the invention may provide in an actuation system that the UWB sensor unit, in particular the processing device and / or the interface, is designed to transmit information, in particular authentication information of a user, and / or a function code, in particular calculated by the processing device, for a corresponding actuation function to the vehicle-side control unit and / or directly to the moving part.

[0048] Furthermore, it is conceivable that the UWB sensor unit, in particular the processing device and / or the interface, may be designed to functionally connect the UWB sensor unit to a security system, in particular an access system, of the vehicle.

[0049] Advantageously, the UWB sensor unit can use the processing device and / or the interface to generate complete function codes for corresponding actuation functions and transmit them directly to a locking system of the moving part. Thus, the UWB sensor unit can form an autonomous actuation system that can operate independently of the vehicle's control unit to actuate the moving part. It can also be advantageous for the UWB sensor unit and all its components to be housed within a single enclosure. This enclosure can include at least one housing element, which is described in detail below.

[0050] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the interface, has a connector for electrically, electronically, and / or data-wise connecting the UWB sensor unit to the vehicle's control unit. Advantageously, the connector can be designed to allow the UWB sensor unit to be attached to the vehicle as a single, manageable unit. In this way, the UWB sensor unit can be easily and conveniently connected to or installed in the vehicle as a combined, individually manageable, and / or integrated module unit, and preferably attached at the same time.

[0051] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the connector, has at least one locking element for attaching the UWB sensor unit to the vehicle in a form-fit and / or force-fit manner. Thus, the UWB sensor unit can be attached to or in the vehicle not only easily and conveniently but also reversibly, e.g., for replacement or repair.

[0052] Furthermore, the invention can provide, in an actuation system, that the UWB sensor unit, in particular the connector, has at least one guide element to guide the UWB sensor unit in a predefined direction during mounting on the vehicle. This facilitates the installation of the UWB sensor unit on or in the vehicle. The guide element can also ensure that the module unit is mounted in the correct position on or in the vehicle.

[0053] Furthermore, the invention can provide, in an actuation system, a housing element to at least partially or completely enclose and / or seal the UWB sensor unit. In this way, the UWB sensor unit can be protected from environmental influences. The housing element can preferably be made of plastic to allow the UWB pulses to pass through.

[0054] Furthermore, the invention can provide, in an actuation system, that the housing element is designed in the form of a housing shell, which is preferably attached over the UWB sensor unit after the UWB sensor unit has been attached to the vehicle, in order to cover and / or seal the UWB sensor unit. This provides an elegant solution for first attaching the UWB sensor unit and then covering and / or sealing it.

[0055] Furthermore, the invention can provide, in an actuation system, that the housing element comprises a first housing shell and a second housing shell to fully enclose and / or seal the UWB sensor unit. In this way, the UWB sensor unit can be provided as a completely enclosed and / or sealed assembly even before installation on or in the vehicle.

[0056] Furthermore, the invention may provide, in an actuation system, that the housing element has at least one locking element for positive-locking and / or force-locking attachment to or in the vehicle or to the UWB sensor unit, and / or that the housing element has at least one guide element for guiding the housing element in a predefined direction during attachment to or in the vehicle or to the UWB sensor unit. In this way, the attachment of the housing element together with the UWB sensor unit to or in the vehicle, or the attachment of the housing element without the UWB sensor unit to the UWB sensor unit already attached to the vehicle, can be carried out simply, conveniently, and reversibly.

[0057] Furthermore, the problem according to the invention is solved by a vehicle with at least one actuation system for at least one movable part of the vehicle, which can be designed as described above. The vehicle according to the invention achieves the same advantages described above in connection with the actuation system. These advantages are fully referenced herein.

[0058] Advantageously, one or more UWB sensor units can be provided in or on the vehicle for one, several, or each moving part of the vehicle. Furthermore, it is conceivable that one or more UWB sensor units, particularly on the interior, can be located on a rear section, a bumper, a diffuser, a structural component, an A-, B-, and / or C-pillar, a side section, and / or a corresponding moving part. In this way, the actuation system can provide various actuation functions for different moving parts.

[0059] Advantageously, a module unit can be designed to transmit not only the results of communication and / or detection to a user-side mobile device, in particular a mobile phone, but also a command code.

[0060] The command code can be used to induce the mobile device to inform a user about the interaction with the module unit (i.e., about the results of communication and / or detection and / or about corresponding vehicle functions) that were activated using the module unit.

[0061] In other words, the module unit can cause the user's mobile device, in particular a mobile phone, to inform a user about the interaction with the module unit (i.e., about the results of communication and / or detection and / or about corresponding vehicle functions) that were activated using the module unit.

[0062] The user's mobile device can provide the user with haptic feedback, e.g., through vibration (e.g., using a piezo unit), acoustic feedback, e.g., through ringing, and / or visual feedback, e.g., through displays on the screen.

[0063] Haptic, acoustic and / or visual feedback from the mobile device can be advantageous for keyless and / or contactless access systems to a vehicle or other object, such as a garage, for example: for locking and / or unlocking a central locking system, so-called active keyless entry systems or passive keyless entry systems, and / or for opening and / or closing movable flaps, so-called motion and / or gesture control, preferably for contactless operation of flaps, in particular tailgates, fuel filler flaps, plug flaps, doors, door handles and / or mirrors, for operation, e.g. for opening and / or closing, a garage door.

[0064] The user can receive haptic / acoustic feedback via vibration / ringing of the mobile device indicating that their movement / gesture has been recognized, and / or that access to the vehicle has been granted, and / or that a movable flap is being opened as intended, etc. This can not only increase comfort but also enhance safety when triggering vehicle functions activated by the module unit.

[0065] Haptic, acoustic and / or visual feedback from the mobile device can still be advantageous when navigating in a parking garage, e.g. when reaching a garage door.

[0066] For vehicle assistance systems, such as seat occupancy detection, child seat detection, and / or dog-in-vehicle detection, it can be advantageous to transmit the results of communication and / or detection performed using the module unit and / or via corresponding vehicle functions activated by the module unit to a user's mobile device. A command code can also be transmitted from the module unit to the mobile device in this process.

[0067] The user's mobile device can issue a message, warning, or alarm to inform the user. A message, warning, or alarm may be issued, for example, if a child or dog is still in the vehicle. The message, warning, or alarm can be delivered visually, for example, via a display, haptically, for example, by vibration, and / or audibly, for example, by the mobile device ringing.

[0068] Furthermore, a warning / alarm can be issued depending on the distance to the vehicle and / or the vehicle's status (e.g., central locking engaged). The frequency and / or volume of the warning / alarm can be increased incrementally as the user moves further away from the vehicle. This can be a cascade of warnings.

[0069] The following scenarios are also conceivable: When the engine is switched off, a visual notification is issued, for example, via a display on the mobile device. When leaving the vehicle and moving away from it, a haptic and / or audible warning / alarm is triggered, for example, by vibration and / or ringing of the mobile device, possibly with graduated frequency and / or volume of the warning / alarm, a so-called warning cascade.

[0070] Initially, if the engine is switched off and / or the user is within a short distance of the vehicle, e.g., approximately 1 or 2 meters, they can be notified via their mobile device that a child or dog is inside the vehicle. The user can then be offered an option via their mobile device to confirm that everything is alright, for example, by briefly closing the garage or going to the trunk. If the user is at a greater distance, e.g., over 1 or 2 meters, and no action is taken by the user, a haptic and / or audible warning / alarm can be triggered via the mobile device. Additionally, an alarm can be activated on the vehicle itself.

[0071] Additionally, simple locking of doors / hatches can be prevented if a child / dog is in the vehicle, but after the user has left the vehicle.

[0072] Furthermore, a double safety function can be provided for locking doors / hatches. For this to work, the user must actively and repeatedly request the vehicle to lock, e.g., twice, before the locking process actually begins.

[0073] Furthermore, it may be advantageous if the module unit is designed to provide gesture control in the interior for at least one of the following vehicle functions, such as: Control of interior lighting, especially in the rear seat area, control of radio, control of air conditioning, etc.

[0074] Furthermore, the object of the invention is achieved by a method for actuating a movable part, in particular a door or a flap, of a vehicle using an actuation system, which can be designed as described above, comprising at least one UWB sensor unit, wherein the UWB sensor unit is operated in a first mode as a detection unit for detecting a movement pattern, and wherein the UWB sensor unit is operated in a second mode as a communication unit for communicating with a user-side mobile device in order to transmit at least one result of the detection and / or communication to the vehicle-side control unit and to actuate the movable part depending on the result. The method according to the invention achieves the same advantages described above in connection with the actuation system.These advantages are fully taken into account here.

[0075] Furthermore, the invention can provide that the UWB sensor unit is operated simultaneously in the first mode and in the second mode, or that the UWB sensor unit is operated alternately in the first mode or in the second mode. Depending on the desired specifications of the module unit, one or the other method of operating the module unit may be advantageous. Alternating operation of the module unit ensures that communication and detection do not overlap. Synchronous operation of the module unit allows communication and detection to occur in parallel, and the actuation functions can be provided quickly.

[0076] Furthermore, the invention can provide that the UWB sensor unit is operated in the first mode or in the second mode depending on the speed and / or state of the vehicle. In this way, the functionality of the UWB sensor unit can be advantageously extended.

[0077] Furthermore, the invention may provide in a method that the module unit in the first mode is used to perform a detection, in particular by means of a time-of-flight measurement of UWB pulses, in order to: a presence of a user or person and / or object, a distance to a user and / or object, a position of a user and / or object, and / or an approach of a user and / or object, a specific sequence of movements by a hand or foot of the user.

[0078] Furthermore, the invention may provide in a method that the UWB sensor unit in the first mode is used to support at least one vehicle assistance system for outside area monitoring, such as in particular: Proximity sensor, motion sensor, and / or motion pattern recognition sensor.

[0079] Furthermore, the invention may provide in a method that the UWB sensor unit in the second mode is used to carry out communication, in particular by means of a digital radio transmission, preferably by means of pulse phase modulation, in order to query, receive and / or verify information, in particular authentication information of a user, from a user-side mobile device, and / or that the UWB sensor unit in the second mode is used to send the results of the communication and / or the detection to the user-side mobile device.

[0080] 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.

[0081] In the following figures, identical reference numerals are used for the same technical features even for different embodiments.

[0082] The Figure 1 , 2 and 6 Each shows an exemplary actuation system S for a movable part 202, in particular a door (cf. Figure 6 ) or a flap (cf. Figure 1 and 2), of a vehicle 200, preferably in the form of an access system to a vehicle interior, a functional space, or a functional element of the vehicle 200, with further embodiments of the actuation system S being conceivable. The actuation system S according to the invention comprises at least one UWB sensor unit 100, which can also be referred to as a module unit. According to the invention, the (meaning one and the same) UWB sensor unit 100 is designed to perform a detection D (i.e., a detection with only one device 100) of a movement pattern M of a user B, in particular a body part B1, B2, preferably a foot B1 or a hand B2, of the user B. At the same time, the UWB sensor unit 100 is designed to perform a communication K (i.e.,a data exchange between two devices 100, 300) with a user-side mobile device 300 is carried out to transmit at least one result of the detection D and / or communication K to the vehicle-side control unit 201 and, depending on the result, to actuate the moving part 202. Exemplary UWB sensor units 100 are shown in the . Figures 3 to 5 and 7 to 9 shown.

[0083] As it is Figures 3 to 5 and 7 to 9To illustrate, the UWB sensor unit 100 can include a UWB transceiver 3, for example, in the form of a UWB front-end module. The UWB sensor unit 100 can also include a processing device 4, for example, in the form of an electronic processing arrangement, which can use, for example, a microcontroller for processing. The processing device 4 can control the UWB transceiver 3 and process the electrical signals sent and / or received by the UWB transceiver 3 in order to evaluate the communication K and / or the detection D and to obtain a result or information based on the communication K and / or the detection D. Depending on the evaluation of the communication K and / or the detection D, the processing device 4 can also generate a complete function code F for actuation (including actuation functions such as...).B: Open, close, unlock, lock) of the moving part 202 to trigger a corresponding actuation function.

[0084] The UWB sensor unit 100 can also have an interface 5, e.g., in the form of an electronic interface, which can connect the UWB sensor unit 100 electrically, control-wise, and data-wise to a control unit 201 of the vehicle 200 in order to, for example, transmit the results of the communication K and / or the detection D to the control unit 201 via the interface and / or trigger at least one corresponding actuation function for actuating the moving part 202 via the interface 5 depending on the communication K and / or the detection D. The interface 5 is also used in conjunction with the Figure 7 described.

[0085] Furthermore, it is conceivable that the UWB sensor unit 100 could have an interface 5, for example in the form of an electronic interface, which could connect the UWB sensor unit 100 electrically, control-wise, and data-wise to a locking system of the moving part 202 in order to actuate the moving part 202. Thus, the UWB sensor unit 100 could form an autonomous actuation system S to actuate the moving part 202 independently of the control unit 201 of the vehicle 200. The processing device 4 could thereby form an autonomous control unit for actuating the moving part 202.

[0086] The electrical signals transmitted and / or received by the UWB transceiver 3 of the UWB sensor unit 100 can be specific for communication K and / or detection D. Based on these electrical signals, the processing device 4 can determine the result of detection D and / or communication K.

[0087] A result of a detection D can include at least one piece of information about whether a user B or a person and / or object is near the UWB sensor unit 100, is approaching the UWB sensor unit 100, is moving or is moving in a special way.

[0088] A result of communication K between the UWB sensor unit 100 and a user-side mobile device 300 can include at least one piece of information about the user B, e.g. an authentication information ID.

[0089] Via interface 5, the UWB sensor unit 100 can transmit not only the authentication information ID and / or a result of detection D and / or communication K, but also a function code F to actuate the moving part 202 to the user-side device 201 or to a locking system of the moving part 202.

[0090] A result of communication K between the UWB sensor unit and / or the user's mobile device 300 can also include navigation data, message data, music data, but also operating data for a vehicle-side device, such as lighting, heating, air conditioning and the like.

[0091] A signal for communication K can, for example, be a defined sequence of short UWB pulses. This defined sequence of short UWB pulses, which can be time-stamped, for instance, can be generated using pulse-phase modulation within a digital radio transmission. In this process, a UWB pulse is shifted in phase relative to a constant reference clock. The phase shift between the UWB pulses symbolizes the information, such as an authentication ID. The period and amplitude of the UWB pulses remain constant.

[0092] A UWB pulse can be represented, for example, as part of a sinusoidal oscillation of a limited duration of a few nanoseconds or even picoseconds, corresponding to a broad spectral line of at least 5 GHz, in particular 7.5 GHz, up to over 8.8 GHz.

[0093] Due to the extremely short UWB pulses, a high transmission rate of 480 to 1320 Mbit / s can be achieved in communication, e.g. using digital radio transmission.

[0094] Due to the extremely short UWB pulses, a high resolution of a few millimeters to even micrometers can be achieved in detection, e.g. by measuring the time of flight of the UWB pulses.

[0095] The invention recognizes that high-resolution detection for motion pattern recognition, with a resolution of a few millimeters to even micrometers, can be achieved using UWB technology, for example, by measuring the time of flight of the UWB pulses. The actuation system S according to the invention can then detect the finest motion patterns M. A motion pattern M in the example of... Figure 1 and 2 This could be, for example, a kicking motion, a forward movement, a backward movement, and / or a foot-kicking motion with a foot B1 of user B. Even the slightest toe movements can be detected by the actuation system S according to the invention. In the example of the Figure 6 A movement pattern M can be in the form of a back-and-forth movement with one hand B2 of the user.

[0096] Advantageously, the invention can provide that the UWB sensor unit 100 and the processing device 4 can form a complete, modular, and autonomous actuation system S for actuating the movable part 202. This means that the processing device 4 can take over the control of the movable part 202 or form a control unit for actuating the movable part 202. Preferably, the UWB sensor unit 100 and the processing device 4 are housed in a housing element 20, as described in detail below in conjunction with the Figures 8 and 9 is described.

[0097] Using several UWB sensor units 100, the actuation system S according to the invention can quickly and with high resolution detect complicated 2D or 3D movement patterns.

[0098] For different actuation functions, the actuation system S according to the invention can detect different movement patterns M with respect to the at least one UWB sensor unit 100. It is conceivable that the actuation system S can be configured to detect a first movement sequence, particularly in a first direction, which can, for example, serve to cause the movable part 202 to open, and / or that the actuation system S can be configured to detect a second movement sequence, particularly in a second direction, which is preferably opposite to the first direction, which can, for example, serve to cause the movable part 202 to close. Furthermore, it is conceivable that the actuation system S can be configured to detect a third movement sequence, particularly in the form of a, preferably simple or double, tapping movement or a rotational movement in a first direction of rotation, which can, for example,which can serve to unlock the movable part 202, and / or that the actuating system S can be designed to detect a fourth movement sequence, in particular in the form of a, preferably simple or double, tapping movement or a rotational movement in a second direction of rotation, which is preferably opposite to the first direction of rotation, which can, for example, serve to lock the movable part 202.

[0099] The actuation system S according to the invention can preferably be programmed as desired, specifying which movement patterns can trigger which actuation functions. The actuation system S according to the invention can also be programmed as desired to adjust the detection ranges, for example, to adapt the detection D to the size of the user B.

[0100] A corresponding user-side mobile device 300 can also be part of the actuation system S. The mobile device 300 can preferably be designed as a mobile phone, in particular a smartphone, or tablet or smartwatch, in order to achieve the desired data exchange using communication K with the UWB sensor unit 100.

[0101] As it is Figures 1 to 9As indicated, the UWB sensor unit 100 can be configured as a modular unit (or as a single node, or in other words, a satellite), preferably a multifunctional unit, preferably in the form of a hardware unit, for providing different actuation functions for one, several, or each moving part 202 of a vehicle 200. Preferably, the UWB sensor unit 100 can form a complete actuation system S for a moving part 202. In this way, a modular, complete, and autonomous actuation system S for actuating the moving part 202 can be provided. In the case of an actuation system S for a tailgate, such a modular actuation system S can also be referred to as a kick sensor system. Here, too, it can be advantageous for the actuation system S to be arranged within a housing element 20.

[0102] Furthermore, the Figure 2 Schematically, in an actuation system S according to the invention, one or more UWB sensor units 100 can be provided for a moving part 202. Multiple UWB sensor units 100 can assist in obtaining high 2D or 3D resolution for motion pattern recognition during detection D. Thus, complex movements can be captured with high resolution using multiple UWB sensor units 100.

[0103] As it is Figure 1 , 2 and 6 To illustrate schematically, one or more UWB sensor units 100 can be arranged, in particular on the inside, e.g. on a rear area, on a bumper, on a diffuser, on a structural component, on an A-, B- and / or C-pillar and / or on the moving part 102.

[0104] Furthermore, the Figure 1 , 2 and 6, that the UWB sensor unit 100 can use communication K to check whether the appropriate user-side mobile device 300 can identify itself in the vicinity of the UWB sensor unit 100 in order to grant access to a vehicle interior (e.g. passenger compartment), a functional space (e.g. trunk) or a functional element (e.g. refueling or charging port) of the vehicle 200 only to an authorized user B.

[0105] As it is Figures 3 to 5 As shown, the UWB antenna 1 can be used for communication K and for detection D as a common UWB antenna unit (see the Figure 3 ) or two separate UWB antenna units 1a, 1b (see the Figures 4 and 5 ) exhibit. It is conceivable that communication K and detection D occur simultaneously (cf. the Figure 4 ) or sequentially (see the Figures 3 and 5 ) can be carried out.

[0106] The UWB antenna 1 can be operated in a frequency range with a bandwidth of at least 500 MHz to several MHz, preferably between 30 MHz and 10.6 GHz, and more preferably between 3.0 and 10.6 GHz. The UWB antenna 1 can, for example, be applied to the printed circuit board 10 using a photolithographic process.

[0107] As it is Figure 4 As shown, the UWB transceiver 3 can have at least one first UWB front-end module 3a for a first UWB antenna unit 1a and a second UWB front-end module 3b for a second UWB antenna unit 1b. Thus, the first UWB antenna unit 1a and the second UWB antenna unit 1b can be operated simultaneously.

[0108] As it is Figure 5As shown, the UWB transceiver 3 can be configured as a single UWB front-end module for a first UWB antenna unit 1a and a second UWB antenna unit 1b. This allows the first UWB antenna unit 1a and the second UWB antenna unit 1b to operate alternately. The UWB transceiver 3 can include a switching unit 2 to control the first UWB antenna unit 1a and the second UWB antenna unit 1b for communication K or detection D. The switching unit 2 can, for example, be an electronic switch, preferably an RF switch.

[0109] Furthermore, in a UWB sensor unit 100 according to the invention, it can be advantageous that the medium frequency and / or the bandwidth of the UWB antenna 1 can be variably adjusted during detection. It is also advantageously conceivable that switching between different medium frequencies of the UWB antenna 1 is possible, e.g., using the UWB transceiver 3. Thus, the detection D by the UWB antenna 1 can be flexibly adapted to different humidity conditions.

[0110] Furthermore, in a UWB sensor unit 100 according to the invention, it can be advantageous that measurements by the UWB antenna 1 during detection D can be calibrated using measurements by the UWB antenna 1, in particular using the transit times of the UWB pulses, during communication K. For this purpose, the transit times of the UWB pulses between the module unit 100 and a user-side mobile device 300, which is positioned at a known distance from the module unit 100, can be measured during communication K. These transit times can be used to refine the accuracy of detection D by the UWB antenna 1, e.g., during distance measurement, and to calibrate the UWB antenna 1 for performing detection D.

[0111] Furthermore, it can be advantageous that the angle of incidence of the UWB antenna 1 can be variably adjusted, for example to set and / or align the measurement ranges for carrying out the detection D.

[0112] In addition to the examples shown in the Figure 1 and 6 A detection D can be performed using the UWB sensor unit 100 to detect: a presence of a user B and / or an object, a distance to a user B and / or an object, a position of a user B and / or an object, and / or an approach of a user B and / or an object, a specific movement sequence by a hand (B2) or a foot (B1) of the user.

[0113] In this way, the module unit 100 can serve as a detection unit, preferably by evaluating the runtime of UWB pulses, such as: Proximity sensor, motion sensor, and / or motion pattern recognition sensor.

[0114] As it is in the Figure 1 , 2 and 6 As indicated, the UWB transceiver 3 of the UWB sensor unit 100 can be configured to control the UWB antenna 1 for carrying out communication K, e.g. by means of a digital radio transmission, e.g. by means of pulse phase modulation, in order to query, receive and / or verify information, such as an authentication information ID of a user B, from a user-side mobile device 300.

[0115] Furthermore, the Figure 1 , 2 and 6 , that the UWB transceiver 3 of the UWB sensor unit 100 may be configured to transmit the results of communication K and / or detection D to a user-side mobile device 300.

[0116] The processing device 4 and / or the interface 5 of the UWB sensor unit 100 can in turn be configured to transmit information, in particular authentication information ID of the user B, and / or a function code F, preferably calculated by the processing device 4, for a desired actuation function for actuating the moving part 202 to the vehicle-side control unit 201 or to a locking system of the moving part 202 (see the Figures 3 to 5 Advantageously, the processing device 4 and / or the interface 5 can be designed to functionally connect the module unit 100 to a safety system, in particular a warning system, of the vehicle 200.

[0117] In general, it is conceivable that the UWB sensor unit 100 can be used for outdoor surveillance.

[0118] As it is Figure 7 as well as the Figures 8 and 9As shown, the (especially electronic) interface 5 can have a (especially mechanical) connector 5a to connect the module unit 100 mechanically, electrically and in terms of data technology to the vehicle-side control unit 201.

[0119] As it is Figures 7 to 9 As indicated, connector 5a can be designed to attach the UWB sensor unit 100 as a separately handleable unit to or in the vehicle 200. For this purpose, connector 5a can have a locking element 101 to secure the UWB sensor unit 100 to or in the vehicle 200 in a form-fit and / or force-fit manner. In addition, connector 5a can have at least one guide element 102 to guide the UWB sensor unit 100 in a predefined direction during attachment to or in the vehicle 200 and to facilitate the attachment of the UWB sensor unit 100.

[0120] As it is Figure 6 and 7As indicated, a housing element 20 may be provided for a UWB sensor unit 100 in order to enclose and / or seal the module unit 100 at least partially or completely.

[0121] As it is Figure 6 As indicated, the housing element 20 can be designed in the form of a housing shell, which can preferably be attached over the UWB sensor unit 100 after the UWB sensor unit 100 has been attached to or in the vehicle 200 in order to cover and / or seal the module unit 100.

[0122] As it is Figure 7 As indicated, the housing element 20 can have a first housing shell 21 and a second housing shell 22 to fully enclose and / or seal the UWB sensor unit 100. In this way, the module unit 100 can be provided as a completely enclosed and / or sealed assembly even before being mounted on or in the vehicle 200.

[0123] It is also possible that the housing element 20 can be designed as a one-piece, e.g. shell-like and / or cup-like, housing element, e.g. with a lid, in order to fully enclose and / or seal the UWB sensor unit 100.

[0124] Furthermore, it is conceivable that the UWB sensor unit 100 can be overmolded with a potting compound inside the housing element 20.

[0125] As it is Figures 8 and 9 Furthermore, as shown, at least one locking element 23 can be provided on the housing element 20 in order to secure the housing element 20 to or in the vehicle 200 in a form-fit and / or force-fit manner (see the Figure 7 ) or at module unit 100 (see the Figure 6 ) to attach. It is also conceivable that the housing element 20 can have at least one guide element 24 in order to guide the housing element 20 in a predefined direction when it is attached to or in the vehicle 200 or to the UWB sensor unit 100.

[0126] In the example of the Figure 6 The housing element 20 can be easily slid onto a corresponding guide of the UWB sensor unit 100 using the guide element 24. In the example of the Figure 7 The housing element 20 with the UWB sensor unit 100 contained therein can be slid onto a corresponding guide on or in the vehicle 200 using the guide element 24.

[0127] A vehicle 200 with at least one actuation system S for at least one, for several, or for each movable part 202 of the vehicle 200, which can be designed as described above, also represents an aspect of the invention, as described above. Figure 1 and 6 clarify.

[0128] A method for actuating a movable part 202, in particular a door or a flap, of a vehicle 200, using an actuating system S, which can be designed as described above, also constitutes an aspect of the invention. In a first mode I, the UWB sensor unit 100 is operated as a detection unit for detecting D a movement pattern M of a user B, in particular a body part B1, B2, preferably a foot B1 or a hand B2, of the user B. Furthermore, in a second mode II, the UWB sensor unit 100 is operated as a communication unit for communicating K with the user's device 300.

[0129] Furthermore, the UWB sensor unit 100 can be operated in either mode I or mode II, depending on the speed and / or condition of the vehicle 200. This allows for a significant expansion of the functionality of the UWB sensor unit 100.

[0130] The preceding explanation of the embodiments describes the present invention solely by way of examples. Naturally, individual features of the embodiments can be freely combined with one another, provided this is technically feasible, without departing from the scope of the present invention.
