Abstract
Description
Technical Field
[0001] The present invention relates to a vehicle comprising one or more pyrotechnic components, such as a driver airbag module or a seatbelt tensioner. In particular, the present invention relates to a method and a corresponding control device, which can be used to effectively and reliably prevent the unauthorized installation of pyrotechnic components. Background Art
[0002] A vehicle may include one or more pyrotechnic components, such as an airbag module or a seatbelt tensioner. For example, the airbag module may be part of the vehicle's steering wheel, into which the airbag is integrated. When the airbag is deployed, the propellant in the airbag module is electrically ignited, and the inflated airbag exerts its protective effect.
[0003] After a triggering, the airbag module must be completely replaced; selective repair of the module is typically not possible. Because airbag modules can be relatively expensive, retrieval crimes have developed, in which airbag modules are removed from other vehicles and / or stolen. These airbag modules are then improperly installed in vehicles that have already triggered them, requiring replacement. Summary of the Invention
[0004] The theft of airbag modules results in losses for vehicle users and insurance companies. This document addresses the technical objective of effectively and reliably prohibiting the unauthorized installation of pyrotechnic components, in particular airbag modules, in vehicles, in particular in order to eliminate the associated theft crimes.
[0005] This object is achieved by a control device according to the invention for triggering a pyrotechnical component of a vehicle and a method for protecting against unauthorized installation of a pyrotechnical component in a vehicle.
[0006] According to one aspect, a control device for triggering a pyrotechnic component of a (motor vehicle), in particular an airbag module or a seat belt tensioner, is described. The control device can be designed to be installed in an onboard electrical system of the vehicle.
[0007] The control device is configured to determine and store a triggering condition for the pyrotechnic component. The triggering condition can, for example, be stored in a memory unit of the control device, e.g., as a flag. The triggering condition can, for example, indicate a triggered state or a non-triggered state. The control device can be configured to trigger the pyrotechnic component connected to the control device when necessary (e.g., in the event of an accident) if the triggering condition indicates a non-triggered state. Alternatively, the control device can (optionally) be configured to prevent triggering of the pyrotechnic component connected to the control device if the triggering condition indicates a triggered state. Thus, if the triggering condition indicates a triggered state, a triggering block can optionally be caused. Furthermore, (preferably) a display element of the vehicle can be activated or kept activated to indicate the triggered state of the triggering condition to the vehicle user. Thus, if the triggering condition indicates a triggered state, resetting of a display element of the vehicle (e.g., a warning light) can be prevented.
[0008] The control device can be configured such that, if the trigger condition indicates an untriggered state, the control device and the pyrotechnic components in the vehicle can be operated without deactivating the pyrotechnic components. This allows for efficient, one-time installation of the pyrotechnic components in the vehicle and / or in conjunction with the control device. For example, the trigger condition can be in the untriggered state as standard. This allows for installation of the pyrotechnic components in the vehicle during vehicle manufacturing without performing a deactivation process.
[0009] Furthermore, the control device can be configured to reset the trigger condition from the triggered state to the untriggered state if the trigger condition indicates a triggered state (and therefore a triggering of the initially installed pyrotechnic component has already occurred) upon deactivation of the pyrotechnic component. In particular, the control device can be configured to reset the trigger condition from the triggered state to the untriggered state only if a pyrotechnic component (newly installed in the vehicle) has been deactivated. Alternatively or additionally, the control device can be configured to retain the trigger condition in the triggered state if a pyrotechnic component (newly installed in the vehicle) has not been deactivated.
[0010] The control device can also be configured to reset a display element of the vehicle for displaying a triggered pyrotechnic component when, in particular only when, the triggering condition is reset from a triggered state to an untriggered state. Alternatively or additionally, the control device can be configured to trigger (if necessary, newly) a pyrotechnic component installed in the vehicle only when necessary (e.g., in the event of a vehicle accident) when, in particular only when, the triggering condition is reset from a triggered state to an untriggered state.
[0011] The control device can therefore be configured to inhibit the operation of a pyrotechnic component newly installed in the vehicle if a successful release of the newly installed pyrotechnic component has not been carried out. This reliably prevents a pyrotechnic component (if it could be stolen) from being installed in the vehicle.
[0012] The control device thus makes it possible to effectively and reliably prevent the unauthorized installation of pyrotechnical components, such as airbag modules, in particular in order to eliminate the associated criminal access.
[0013] The pyrotechnic component may include an identification device configured to uniquely identify the pyrotechnic component from among a plurality of different pyrotechnic components (and corresponding plurality of identification devices). The plurality of identification devices for the plurality of different pyrotechnic components that are authorized or deregistered as replacement parts may be stored on a backend server.
[0014] The identification means can effectively include a machine-readable code, in particular a barcode or a QR code, with the serial number of the pyrotechnic component. Alternatively or additionally, the identification means can include a human-readable serial number of the pyrotechnic component.
[0015] The release of a (newly) installed pyrotechnic component in a vehicle can then be performed reliably and efficiently based on the pyrotechnic component's identification device (e.g., by comparing this identification device with a plurality of identification devices of a plurality of different pyrotechnic components that are authorized or released as replacement parts). In particular, the control device can be configured to release or not release a (newly) installed pyrotechnic component in a vehicle based on the pyrotechnic component's identification device. This allows for efficient and reliable release of a (newly) installed pyrotechnic component in a vehicle.
[0016] The control device can be configured to detect that a new pyrotechnic component has been installed in the vehicle if the trigger condition indicates a triggered state. This can be detected, for example, based on the resistance of the pyrotechnic component. For example, a previously triggered pyrotechnic component and a (new) pyrotechnic component that has not yet been triggered can have different resistance values. The control device can be configured to detect the resistance value of the pyrotechnic component connected to the control device.
[0017] Furthermore, the control device can be configured to detect that the new pyrotechnic component meets one or more technical conditions, in particular one or more technical conditions with respect to electrical resistance, which (in principle and / or purely technically) allow the triggering condition to be reset from a triggered state to a non-triggered state. In particular, it can be detected that the pyrotechnic component has one or more technical conditions which allow operation, i.e., triggering of the pyrotechnic component when required.
[0018] Even if a newly installed pyrotechnic component meets one or more of the technical conditions for operation in the vehicle, the control device can first check whether the new pyrotechnic component is released. The triggering condition can then be reset from the triggered state to the untriggered state only if, and in particular, only if, the new pyrotechnic component is released. This makes it possible to prevent the unauthorized installation of new pyrotechnic components in the vehicle in a particularly reliable manner.
[0019] The control device can be configured to check whether a valid decryption code for decrypting the pyrotechnic component has been entered via a user interface and / or a maintenance interface of the vehicle. The decryption code can be determined and entered, for example, by service personnel in a workshop based on an identification device of the (newly installed) pyrotechnic component. The triggering condition can then be reset from a triggered state to a non-triggered state if, and in particular, only if, a valid decryption code has been entered. This effectively prevents the unauthorized installation of new pyrotechnic components in the vehicle.
[0020] The control device can be configured to determine and store a plurality of different triggering conditions for a plurality of different pyrotechnic components of the vehicle and to reset these different triggering conditions when a newly installed pyrotechnic component is released. In other words, the control device can be designed to operate a plurality of different pyrotechnic components (for different functions, such as different airbag modules or seatbelt tensioners) and monitor them for impermissible replacements. The different pyrotechnic components can be connected to different interfaces of the control device.
[0021] As described above, the triggering condition can be in an untriggered state as standard during vehicle production, so that the pyrotechnic component can be installed in the vehicle without releasing the pyrotechnic component during vehicle production and can subsequently be triggered by the control device when required (during vehicle operation). This also allows for efficient vehicle production (without the need for a dedicated release process).
[0022] According to a further aspect, a (road) motor vehicle, in particular a car or a truck or a bus or a motorcycle, is described, which comprises a control device described in this document.
[0023] According to another aspect, a method for protecting against the unauthorized installation of a pyrotechnic component in a vehicle is described. The method includes determining and storing a triggering condition for the pyrotechnic component, wherein the triggering condition indicates a triggered state or an untriggered state. Furthermore, the method includes enabling operation of a control device including the pyrotechnic component in the vehicle without deactivating the pyrotechnic component if the triggering condition indicates an untriggered state. Furthermore, the method includes resetting the triggering condition from the triggered state to the untriggered state if the pyrotechnic component is deactivated if the triggering condition indicates a triggered state.
[0024] The method for deregulating newly installed pyrotechnic components in a vehicle may include, in particular, checking an identification device of the newly installed pyrotechnic component on a backend server of the vehicle manufacturer to determine whether the newly installed pyrotechnic component has been deregistered as a replacement part. Furthermore, the method may include providing feedback to the vehicle's control unit regarding deregistration or non-deregistration to trigger the newly installed pyrotechnic component. The generation and checking of the identification device may be implemented in a blockchain. This allows for the prohibition of unauthorized installation of pyrotechnic components in a vehicle in a particularly efficient and reliable manner.
[0025] According to another aspect, a software (SW) program is described that can be configured to be executed on a processor (for example, on a control unit of a vehicle) and thereby to carry out the method described in this document.
[0026] According to another aspect, a storage medium is described. The storage medium may include a software program configured to be executed on a processor and thereby perform the method described in this document.
[0027] It should be noted that the methods, apparatuses, and systems described in this document can be applied not only individually but also in combination with other methods, apparatuses, and systems described in this document. Furthermore, each aspect of the methods, apparatuses, and systems described in this document can be combined with each other in various ways. In particular, individual features can be combined with each other in various ways. BRIEF DESCRIPTION OF THE DRAWINGS
[0028] The present invention will now be described in more detail with reference to exemplary embodiments.
[0029] Figure 1a An exemplary vehicle having a pyrotechnic assembly is shown;
[0030] Figure 1b An exemplary pyrotechnic assembly is shown; and
[0031] Figure 2 A flow chart of an exemplary method for protecting against unauthorized installation of a pyrotechnic component is shown. DETAILED DESCRIPTION
[0032] As already mentioned, this document is aimed at providing an effective and reliable protection against unauthorized installation of pyrotechnic components, such as airbag modules. In this regard, Figure 1a A vehicle 100 is shown which includes a pyrotechnical component 110. Pyrotechnical component 110 can be triggered by control unit 101 of vehicle 100, for example, if a collision of vehicle 100 is detected.
[0033] Figure 1b Further details of pyrotechnic component 110 and control device 101 are shown. Control device 101 is configured to ignite ignition unit 112 of pyrotechnic component 110 to trigger pyrotechnic component 110, for example, by applying an ignition voltage to ignition unit 112. Pyrotechnic component 110 is then triggered to provide a specific function (e.g., inflating an airbag). Following this triggering, pyrotechnic component 110 is typically no longer usable and must be replaced.
[0034] Control device 101 may be configured to store a triggering condition 103 of pyrotechnic component 110 (e.g., in a status bit). Triggering condition 103 may indicate whether pyrotechnic component 110 installed in vehicle 100 has already been triggered. If triggering condition 103 indicates that pyrotechnic component 110 has already been triggered, further triggering of pyrotechnic component 110 may be prohibited, if necessary. In other words, triggering of pyrotechnic component 110 by control device 101 may be possible only if triggering condition 103 indicates that pyrotechnic component 110 has not yet been triggered (e.g., if triggering condition 103 indicates an untriggered state).
[0035] Furthermore, control device 101 may be configured to cause a display unit 102 of vehicle 100 , for example on the dashboard of vehicle 100 , to indicate that pyrotechnic component 110 has been triggered (if triggering condition 103 indicates a triggered pyrotechnic component 110 or if triggering condition 103 indicates a triggered state).
[0036] Control device 101 may be designed such that, if necessary, triggering condition 103 can only be reset by authorized service personnel.
[0037] Within the scope of vehicle 100 production, triggering state 103 can, by standard, indicate the non-triggered state of pyrotechnical component 110 . This allows any pyrotechnical component 110 from the stock of pyrotechnical components 110 to be installed in vehicle 100 .
[0038] On the other hand, control device 101 can be configured to check whether newly installed pyrotechnic component 110 is authorized for installation if trigger condition 103 indicates a triggered state for pyrotechnic component 110. In other words, if trigger condition 103 indicates a triggered state, installation and / or subsequent operation of pyrotechnic component 110 can optionally only be performed after successful authorization of newly installed pyrotechnic component 110. This effectively and reliably prevents stolen pyrotechnic component 110 from being installed in another vehicle 100.
[0039] The pyrotechnic component 110 may have an identification means 111 on the housing, for example. The identification means 111 may be designed to uniquely identify the pyrotechnic component 110. A particularly effective identification means 111 is a serial number applied to the pyrotechnic component 110, for example embossed.
[0040] When installing pyrotechnic component 110, it may be necessary for the service personnel to enter the serial number of pyrotechnic component 110 into a server computer and / or via a user interface and / or maintenance interface of vehicle 100. It may then be possible to check (e.g., by comparing with a backend server of the manufacturer of pyrotechnic component 110 and / or vehicle 100) whether pyrotechnic component 110 is authorized for installation in vehicle 100 as a replacement part.
[0041] After successful authorization of the installed pyrotechnic component, the triggering condition 103 can be reset (to the untriggered state). As a result, the display element 102 can also be reset (so that the display no longer indicates that the pyrotechnic component 110 must be replaced). In addition, the control device 101 can support the triggering of the newly installed pyrotechnic component 110 (for example, in the event of an accident).
[0042] A method is described that effectively and reliably prevents the unauthorized installation of pyrotechnic components 110. This method is based on the fact that control device 101 for pyrotechnic components 110 is typically permanently integrated into the onboard electrical system of vehicle 100 and cannot be replaced without complex authorization measures. This reliably prevents unauthorized manipulation of triggering conditions 103. During the manufacture of vehicle 100, the configuration between one or more electrical ignition circuit outputs of control device 101 and one or more pyrotechnic components 110 (e.g., driver airbag, side airbag, driver seatbelt tensioner, etc.) is determined in control device 101. During the triggering process in the event of an accident, the one or more ignition circuit outputs (and therefore the corresponding one or more pyrotechnic components 110) are actuated in a defined sequence, resulting in a triggering event. The entire sequence can be permanently stored in an "event data recorder" (EDR) in control device 101.
[0043] The activation of the ignition circuit (for a specific pyrotechnic component 110) necessarily results in the destruction of the corresponding actuator (i.e., pyrotechnic component 110). After the corresponding activation or triggering, the failure of actuator 110 is detected by control unit 101 and stored in an internal error memory (e.g., as trigger condition 103). Typically, the failure of one or more actuators 110 is permanently displayed to the user of vehicle 100 (e.g., via warning light 102).
[0044] After replacing the actuator (i.e., pyrotechnic component 110), control device 101 can check whether the electrical ignition circuit has been repaired, for example, whether it has the specified resistance again. If so, internal error states, in particular, trigger condition 103, can be reset if necessary. However, if the installed pyrotechnic component 110 has not been previously released by a monitoring entity (e.g., the manufacturer of component 110 and / or the vehicle manufacturer), resetting trigger condition 103 can be prevented.
[0045] Therefore, the error stored in the control device 101, i.e., the reset of the trigger condition 103, is only possible if the newly installed actuator 110 has been released by an authorized entity. If the actuator has not been released, resetting the registered error memory is not permitted. As a result, the error message may continue to be received even after the new actuator 110 has been installed.
[0046] The deregulation process can be realized as follows: Each actuator 110 has its own serial number 111, which can be visibly attached to the corresponding component 110. The serial number 111 can be applied, for example, as a barcode, a QR code and / or in a readable form.
[0047] During production, the manufacturer of the actuators 110 can forward the serial number 111 of each actuator 110 to the manufacturer of the vehicle 100. The transmission and storage of the serial number 111 can occur using IT security measures. A service technician who performs a repair on the triggered actuator 110 can read or scan the serial number 111 of the actuator 110 and electronically transmit it to the manufacturer of the vehicle 100 (e.g., to a backend server). This can be accomplished via a communication link between a computer in the workshop and the manufacturer's server. Information about the repair process (e.g., stored error codes and the serial number 111 of the replacement part 110) can also be transmitted.
[0048] The manufacturer's server can compare the serial number 111 with the stored serial number of the actuator 110 that is permitted as a replacement part. If the configuration is correct, the release can be authorized to correct the error. Otherwise, the release can be prohibited.
[0049] The entire process of generating serial number 111, querying the manufacturer of vehicle 100, and resolving any errors can be implemented in a blockchain. This reliably prevents tampering. Blockchain can also be used to verify data during the manufacturing process of vehicle 100. This can already be done at the manufacturer of actuator 110. This eliminates the need for additional data collection during the manufacturing process of vehicle 100.
[0050] The described process is scalable. If necessary, it can be applied only to one or more critical components 110 of vehicle 100. Non-critical components can be excluded from monitoring (and the associated deregulation process) by appropriate settings in control device 101.
[0051] The pyrotechnic component 110 described in this document can be implemented effectively without additional security measures (identification means 111, in particular serial number 111, are typically already present today). The anti-theft protection only becomes effective if the (already triggered or defective) pyrotechnic component 110 is replaced or replaced. The stored information of the control device 101, in particular the triggering condition 103, is used to implement the anti-theft protection.
[0052] As described above, when pyrotechnic component 110 is triggered, the triggering process is stored in control device 101 as triggering condition 103. At the same time, a corresponding display 102 is typically permanently activated in vehicle 100. Display 102 indicates to the user that the safety system of vehicle 100 is disrupted or not fully functional.
[0053] The stored triggering and the associated resetting of display 102 can be achieved solely by proving that an authorized replacement part has been installed.
[0054] The described process can avoid additional costs in vehicle production because the control device 101 has not yet stored the triggering (ie, the triggering state 103 is in the untriggered state). In this case, each pyrotechnic component 110 is accepted by the control device 101 (without a release process).
[0055] On the other hand, after the origin of the replacement component 110 has been verified (within the scope of the deregulation process), the control device 101 can initially be restored to a fault-free state in the case of maintenance (based on a stored trigger).
[0056] Figure 2 A flow chart shows an exemplary (possibly computer-implemented) method 200 for protecting against unauthorized installation of a pyrotechnic component 110 in a vehicle 100. Method 200 can be (at least partially) executed by control unit 101 of vehicle 100. Method 200 includes determining and storing 201, in particular managing, triggering conditions 103 for pyrotechnic components 110. Triggering conditions 103 can indicate a triggered state (if the pyrotechnic component 110 previously installed in vehicle 100 has already been triggered and is therefore not triggerable again) or a non-triggered state (if triggering of pyrotechnic component 110 is still possible). Triggering conditions 103 can thus indicate a triggered state (e.g., "1") or a non-triggered state (e.g., "0") as a binary variable.
[0057] Method 200 further includes enabling 202 operation of control device 101 together with pyrotechnic component 110 in vehicle 100 without (previously) releasing control of pyrotechnic component 110 if trigger condition 103 indicates an untriggered state. Trigger condition 103 can be in the untriggered state by default. This allows pyrotechnic component 110 to be installed in vehicle 100 during vehicle 100 manufacturing without a release procedure and subsequently used. This allows for an efficient manufacturing process for vehicle 100.
[0058] Method 200 further includes resetting 203 trigger condition 103 from the triggered state to the untriggered state if trigger condition 103 indicates the triggered state and (if necessary, only) if pyrotechnic component 110 is released. If trigger condition 103 is in the triggered state, it may be necessary to carry out a release process for the newly installed pyrotechnic component 110 in order to enable subsequent operation of pyrotechnic component 110 in vehicle 100. This reliably prevents unauthorized installation of pyrotechnic components 110 and associated access crimes.
[0059] The measures described in this document make it possible to effectively and reliably prevent the use of untriggered and potentially stolen pyrotechnic components 110 .
[0060] Furthermore, it may happen that a counterfeit pyrotechnic component 110 is installed in vehicle 100. Counterfeit pyrotechnic component 110 may be designed to meet one or more technical conditions, particularly one or more technical conditions regarding electrical resistance, required to reset triggering condition 103 from a triggered state to an untriggered state. On the other hand, it may happen that counterfeit pyrotechnic component 110 is inoperable (for example, because pyrotechnic component 110 does not have a charge). The measures described in this document can reliably detect and, if necessary, prevent the installation of counterfeit pyrotechnic components 110.
[0061] Furthermore, pyrotechnic components 110 from vehicles that have been damaged by accidents or water are often available on the internet, for example. The exact origin and / or functional status of these pyrotechnic components 110 is often unknown. Typically, it is not possible to ensure that pyrotechnic components 110 from vehicles that have been damaged by water (e.g., due to a flood) will remain operational after drying. The measures described in this document make it possible to reliably identify and, if necessary, prevent the installation of used pyrotechnic components 110.
[0062] The present invention is not limited to the embodiments shown. In particular, it should be noted that the description and the accompanying drawings are intended only to illustrate the principles of the proposed methods, devices, and systems.
