METHOD AND ORDER FOR ALLOCATION OF AT LEAST ONE PIECE OF PROTECTIVE CLOTHING TO AT LEAST ONE CABINLESS VEHICLE

Description

[0001] The invention relates to a method for assigning at least one piece of protective clothing to at least one cabless vehicle. The present invention also relates to an arrangement for carrying out such a method for assigning at least one piece of protective clothing to at least one cabless vehicle, as well as a protective arrangement in a piece of protective clothing and a protective arrangement in a cabless vehicle.

[0002] Modern protective clothing, such as helmets or jackets, for occupants of cabless vehicles (e.g., motorcycles, trikes, quads) is equipped with airbag systems that deploy automatically upon detecting an accident, protecting the rider from serious injuries. These systems can be wired to the vehicle or operate autonomously, using sensors integrated into the protective clothing to determine the triggering event. Furthermore, systems exist that utilize wireless communication between the protective clothing and the cabless vehicle. Such a wireless connection further improves the reliability and accuracy of these systems by enabling early transmission of vehicle-based accident detection information to the protective clothing.

[0003] For example, DE 101 04 019 C1 discloses a motorcycle protective suit which has at least one airbag, whereby the power supply and data communication with the motorcycle are realized via a wireless connection. Coils in the seat area of ​​the motorcycle protective suit are used for power transmission, and microwave communication devices are used for data transmission.

[0004] A major problem with using wireless communication, however, lies in assigning protective clothing to a specific vehicle. Particularly when multiple vehicles and protective clothing are within radio range, it can be difficult to determine which protective clothing, or clothing worn by occupants, is in which vehicle. In the event of an alarm activation, a clear assignment of which protective clothing must deploy is absolutely essential. With multiple occupants wearing corresponding protective clothing and several vehicles within radio range, distinguishing which occupant is in which vehicle, and therefore which protective clothing must deploy in the event of an accident, is not a trivial matter.

[0005] One obvious approach is to manually pair protective clothing and a vehicle to be used immediately before the journey begins, using an assignment procedure.

[0006] For example, EP 1 703 815 B1 discloses a protective garment which includes at least one inflatable protective device and is designed to be worn by a person traveling in a cabless vehicle. The protective garment comprises a power supply unit, a radio receiver configured to communicate wirelessly via an identification code with an associated remote radio transmitter located on the cabless vehicle, an activation circuit for activating the at least one inflatable protective device in response to an alarm signal received from the radio transmitter, and non-volatile memory. The protective garment also includes at least one programmable logic unit connected to the radio receiver.The at least one programmable logic unit manages and stores the identification codes received via the radio receiver in at least one of the non-volatile memory locations. Furthermore, the at least one programmable logic unit allows the wearer of the protective clothing to select a specific code from among those available in the at least one non-volatile memory location via a user interface. The user interface includes at least one push button and a screen with a corresponding driver circuit. To assign the protective clothing to a vehicle without a cabin, a vehicle-side module, comprising a logic unit, an encoder, and the radio transmitter, transmits a serial identification code. When not in use, the components in the protective clothing are in an inactive state with very low energy consumption.When one of the at least one push button is pressed, the logic unit of the protective garment checks the supply voltage and uses the receiver and decoder to search for a valid serial identification code transmitted by the vehicle's module. If the logic unit finds one or more serial identification codes, it stores them in non-volatile memory and displays them on the screen via the associated driver circuitry. Using the at least one push button, the user can then select the serial identification code corresponding to the cabin-less vehicle to be used from among the displayed codes. To simplify the process of identifying the cabin-less vehicle, the logic unit first displays the most recently used serial identification code on the screen when analyzing the values ​​stored in memory.During travel, the vehicle-mounted module transmits the serial identification code and an activation signal to the logic unit of the protective clothing when an acceleration signal detected by a vehicle-mounted sensor unit exceeds a predefined threshold. In response to the received activation signal, the logic unit activates at least one protective device of the protective clothing.

[0007] A disadvantage here is that driver interaction is required each time before starting a journey, for example by pressing a button on the protective clothing and / or on the vehicle in order to find the correct assignment between vehicle and protective clothing(s) when there are several vehicles or protective clothing items nearby.

[0008] EP2632771B1 discloses a device, a system and a method for protective clothing. Disclosure of the invention

[0009] The method for assigning at least one piece of protective clothing to at least one cabless vehicle, as defined in independent claim 1, the arrangement for carrying out the method for assigning at least one piece of protective clothing to at least one cabless vehicle, as defined in independent claim 12, the protective arrangement in a piece of protective clothing, as defined in independent claim 16, and the protective arrangement in a cabless vehicle, as defined in independent claim 17, each have the advantage that a static assignment of the at least one piece of protective clothing with manual interaction is only required once. This allows several pieces of protective clothing to be statically assigned to one cabless vehicle. Additionally or alternatively, one piece of protective clothing can be statically assigned to several cabless vehicles.If necessary, for example in the event of a sale of the cabinless vehicle or disposal of the protective clothing item, the static assignments can be reversed.

[0010] The proposed automatic dynamic assignment of at least one piece of protective clothing to the vehicle being used, performed at least at the start of each journey, dynamically assigns the at least one piece of protective clothing to the vehicle being used for the current journey without any further interaction from the occupant. This allows the vehicle to activate at least one protective device in the at least one piece of protective clothing in the event of a detected accident. During this automatic dynamic assignment, at least one additional state parameter of the at least one piece of protective clothing and / or the vehicle being used is recorded and evaluated.This can advantageously prevent incorrect assignments of protective clothing items and cabinless vehicles in the case of multiple protective clothing items and multiple cabinless vehicles within range of wireless communication.

[0011] Since the automatic dynamic assignment of at least one piece of protective clothing to the cabinless vehicle in use is only performed for the current journey, incorrect assignment of protective clothing cannot occur even if one or more occupants change vehicles during a stopover. For example, two drivers can exchange vehicles, or only one occupant, such as a passenger, can switch from one vehicle to another. This prevents the protective clothing of the injured occupant from failing to activate in the event of an accident, while that of the uninjured occupant, who is within range of the wireless communication link, is still activated. As a prerequisite for such a vehicle change, the corresponding pieces of protective clothing are statically assigned to both cabinless vehicles.

[0012] Embodiments of the present invention provide a method for assigning at least one piece of protective clothing to at least one cabinless vehicle, wherein the at least one piece of protective clothing has at least one protective device which can be activated by the cabinless vehicle used during a journey, wherein the at least one piece of protective clothing and the at least one cabinless vehicle exchange and store corresponding unique authentication information through bidirectional wireless communication when mutually statically assigned.In this process, using the authentication information of the static assignment, at least one additional state variable of the at least one piece of protective clothing and / or the cabin-less vehicle used is recorded and evaluated at least once a journey begins, and a dynamic assignment of the at least one protective device to the cabin-less vehicle used is carried out for the current journey if at least one predefined condition is met when evaluating the at least one additional state variable.

[0013] Furthermore, an arrangement comprising at least one piece of protective clothing and at least one cabinless vehicle is proposed, which is configured to carry out the method according to the invention. The at least one piece of protective clothing has at least one protective device which can be activated by a cabinless vehicle during travel. The at least one cabinless vehicle also has a first communication device, and the at least one piece of protective clothing has a second communication device, wherein the first and second communication devices are configured to establish a wireless communication link between the at least one piece of protective clothing and the at least one cabinless vehicle.A first evaluation and control unit of the at least one cabinless vehicle and a second evaluation and control unit of the at least one piece of protective clothing are designed to perform a mutual static assignment by means of a one-time exchange and one-time storage of corresponding unique authentication information via bidirectional wireless communication.The first evaluation and control unit of the at least one cabin-less vehicle and / or the second evaluation and control unit of the at least one piece of protective clothing are further configured to, at least before each journey, use the authentication information of the static assignment to acquire and evaluate at least one additional state variable of the at least one piece of protective clothing of the occupant and / or the cabin-less vehicle used, wherein the first evaluation and control unit of the cabin-less vehicle used and / or the second evaluation and control unit of the at least one piece of protective clothing are further configured to carry out a dynamic assignment of the at least one protective device to the cabin-less vehicle used for the current journey, if at least one predefined condition is met when evaluating the at least one additional state variable.

[0014] Furthermore, a protective arrangement in a piece of protective clothing is proposed, which is designed to carry out the inventive method in combination with a protective arrangement in a cabinless vehicle.The protective arrangement in the protective clothing piece comprises at least one protective device which can be activated during a journey by a cabinless vehicle, a communication device which is designed to establish a wireless communication link with at least one cabinless vehicle, and an evaluation and control unit which is designed to conduct bidirectional wireless communication with the cabinless vehicle via the communication device and to perform a one-time exchange and one-time storage of corresponding unique authentication information and a mutual static assignment of the cabinless vehicle.The clothing-side evaluation and control unit is further designed to capture at least one additional state variable of the at least one piece of protective clothing of the occupant and / or the cabinless vehicle used, and to evaluate it in communication with the cabinless vehicle used, at least before each journey, using the authentication information of the static assignment. The clothing-side evaluation and control unit is further designed to perform a dynamic assignment of the at least one protective device to the cabinless vehicle used for the current journey if at least one predefined condition is met when evaluating the at least one additional state variable.

[0015] Furthermore, a protective arrangement in a cabin-less vehicle is proposed, which is configured to execute the method according to the invention in combination with a protective arrangement in a protective garment. The protective arrangement in the cabin-less vehicle comprises a communication device configured to establish a wireless communication link with at least one protective garment, and an evaluation and control unit configured to conduct bidirectional wireless communication with the at least one protective garment via the communication device and, in communication with the at least one protective garment, to perform a one-time exchange and one-time storage of corresponding unique authentication information and a mutual static assignment of the at least one protective garment.The vehicle-side evaluation and control unit is further designed to acquire at least one additional state variable of the occupant's protective clothing and / or the cabinless vehicle used, at least before each journey, using the authentication information of the static assignment, and to evaluate this state variable in communication with the occupant's protective clothing. The vehicle-side evaluation and control unit is further designed to perform a dynamic assignment of the protective device to the cabinless vehicle used for the current journey if at least one predefined condition is met during the evaluation of the additional state variable.

[0016] Protective clothing is understood to mean, for example, a jacket or helmet equipped with an activatable protective device. The protective device is preferably designed as an inflatable airbag.

[0017] The static mutual assignment of at least one piece of protective clothing to at least one cabless vehicle is understood below as a process in which the at least one piece of protective clothing and the corresponding cabless vehicle are initially manually associated once. This can be achieved using unique authentication information from the vehicle and the piece of protective clothing, or an authentication tag on the protective clothing, which can be displayed on the vehicle, for example, as "Protective Clothing XY". Manual interaction, for example via a push button, ensures that the association takes place between precisely the desired piece of protective clothing and the desired cabless vehicle. In this process, for example, a secret key generated in the vehicle can be exchanged as authentication information using known and proven methods.The generated secret key can also be communicated to other protective clothing items in subsequent associations that are to be associated with the vehicle. This allows multiple protective clothing items to be statically assigned to the vehicle, as may be necessary, for example, when driving with multiple occupants. Furthermore, a single protective clothing item can also be associated with multiple vehicles, for example, if a driver wants to drive several vehicles alternately. This is made possible by storing multiple secret, vehicle-specific keys.

[0018] This initial association, or static assignment using unique authentication information, prevents potential attack or manipulation scenarios. Without this procedure, an attacker could impersonate a vehicle and send falsified data for automatic dynamic assignment. In the worst-case scenario, this could trigger the protective clothing after the vehicle has started moving, thus exposing the driver to an unnecessary accident risk.

[0019] Embodiments of the present invention advantageously enable an automatic and reliable dynamic assignment at the start of a journey, determining which protective clothing(s) are assigned to which vehicle. Based on the initial static assignment of the at least one piece of protective clothing to the cabless vehicle at the start of the journey, an automatic dynamic assignment can be made between a single piece of protective clothing and the cabless vehicle, or between multiple pieces of protective clothing and the cabless vehicle. During the journey, if an accident is detected, the cabless vehicle can then activate the at least one protective device of the clothing dynamically assigned to the vehicle via further wireless communication.

[0020] For automatic dynamic assignment, the initially established associations or authentication information from the static assignment are used to establish a secure wireless communication connection throughout a specific journey. At the start of the journey, the vehicle initiates secure wireless communication using previously exchanged secret keys. Protective clothing items within range participate in this communication if they have been previously statically assigned or associated with the vehicle being used. A single piece of protective clothing can participate in multiple wireless communications if several vehicles are within range. The protective clothing item then uses the data transmitted by the vehicles within range to determine which vehicle it is traveling on.If automatic dynamic assignment of the protective clothing was possible, the communication link with this vehicle is marked as active in the protective clothing for this journey. This means that only activation signals for the activation of at least one protective device from the vehicle marked as active are considered for this journey. The protective clothing can mark only one vehicle as active for a single journey, but it can also be used for journeys with other vehicles.

[0021] In this context, an evaluation and control unit can be understood as an electrical circuit that processes or evaluates acquired sensor signals. The evaluation and control unit can have at least one interface, which can be implemented in hardware and / or software. In the case of a hardware implementation, the interfaces can, for example, be part of a so-called system ASIC, which incorporates various functions of the evaluation and control unit. However, it is also possible that the interfaces are separate integrated circuits or consist at least partially of discrete components. In the case of a software implementation, the interfaces can be software modules that are present, for example, on a microcontroller alongside other software modules.A computer program product with program code stored on a machine-readable medium such as semiconductor memory, hard disk memory or optical memory, and used to perform the evaluation when the program is executed by the evaluation and control unit, is also advantageous.

[0022] The measures and further developments listed in the dependent claims enable advantageous improvements to the method specified in independent claim 1 for assigning at least one piece of protective clothing to at least one cabin-less vehicle and to the arrangement specified in independent claim 12 for assigning at least one piece of protective clothing to at least one cabin-less vehicle.

[0023] A particular advantage is that, in the static assignment, a first authentication piece of information for the at least one piece of protective clothing is stored in the at least one vehicle, and a second authentication piece of information for the at least one vehicle is stored in the at least one piece of protective clothing. This allows for the simple establishment of a secure wireless communication connection between the at least one piece of protective clothing and the cabinless vehicle.

[0024] In an advantageous embodiment of the method, at least one additional state variable can be evaluated to determine the distance between the at least one piece of protective clothing and the cabless vehicle being used. This allows the at least one piece of protective clothing to be assigned to the cabless vehicle being used for the current journey if the determined distance lies within a predefined range.

[0025] In a particularly advantageous embodiment of the method, a first additional state variable can correspond to an effective first acceleration information of the at least one piece of protective clothing, and a second state variable can correspond to an effective second acceleration information of the corresponding cabin-less vehicle. In this case, the at least one piece of protective clothing can be dynamically assigned to the corresponding cabin-less vehicle for the current journey if the detected effective first acceleration information of the at least one piece of protective clothing and the detected effective second acceleration information of the corresponding cabin-less vehicle are identical within a predefined tolerance range.

[0026] In a further advantageous embodiment of the method, the at least one additional state variable can correspond to authentication information, which can be optically visible or arranged as a readable transponder on the at least one piece of protective clothing and can be detected and evaluated by a vehicle-side sensor device. In this case, the at least one piece of protective clothing can be dynamically assigned to the corresponding cabless vehicle for the current journey if the detected or read authentication information corresponds to authentication information of a piece of protective clothing statically assigned to the cabless vehicle in use.

[0027] In a further advantageous embodiment of the method, the at least one additional state variable can correspond to an engine noise generated by the cabinless vehicle used, which can be detected and evaluated by an acoustic sensor device on the garment. In this case, the at least one piece of protective clothing for the current journey can be dynamically assigned to the corresponding cabinless vehicle if the detected and evaluated engine noises correspond to state data of the engine of the cabinless vehicle used.

[0028] In a further advantageous embodiment of the method, the automatic dynamic assignment of at least one piece of protective clothing belonging to at least one occupant to the vehicle being used can be carried out directly after the vehicle is activated (in the case of a vehicle with an internal combustion engine, this corresponds to switching on the ignition) and before the journey begins, or within a time window after the journey has begun. Furthermore, the dynamic assignment of the at least one piece of protective clothing belonging to at least one occupant to the vehicle being used can be checked periodically or event-driven during the journey. Thus, depending on the technology and the required level of accuracy, the automated dynamic assignment can take place either before the journey begins or shortly thereafter. A dynamic assignment after the journey has begun is considered successful if the cross-correlation of the data, taking other vehicles into account, shows a sufficiently high degree of agreement.A detected dynamic mapping can also be signaled to the driver in the vehicle, giving them the opportunity to intervene if necessary. Furthermore, the dynamic mapping check can either be stopped after the first dynamic mapping with sufficiently high confidence or continued continuously during the journey. The latter allows for the ongoing plausibility check of the data and can signal a lack of correlation to the driver.

[0029] In a further advantageous embodiment of the method, the dynamic assignment of the at least one piece of protective clothing belonging to the at least one occupant to the vehicle used can be reversed after the journey has ended. The end of the journey can be detected, for example, after the vehicle stops, which is recognized by the deployment of a kickstand, or after the vehicle is deactivated; in the case of a vehicle with an internal combustion engine, this corresponds to switching off the ignition.

[0030] In an advantageous embodiment of the arrangement, the at least one piece of protective clothing can have at least one non-volatile storage device configured to store initial authentication information from at least one vehicle. Furthermore, the at least one vehicle can have at least one non-volatile storage device configured to store second authentication information from at least one piece of protective clothing. The different authentication information makes it possible to statically assign several different pieces of protective clothing to a cabinless vehicle, or conversely, to statically assign several vehicles to a single piece of protective clothing.

[0031] In a further advantageous embodiment of the arrangement, the at least one piece of protective clothing and / or the at least one cabinless vehicle can have at least one sensor device configured to detect at least one additional state variable. For the purposes of this document, a sensor unit is understood to be a component comprising at least one sensor element that directly or indirectly detects a physical quantity or a change in a physical quantity and preferably converts it into an electrical sensor signal.

[0032] In a further advantageous embodiment of the arrangement, the at least one cabinless vehicle can have at least one display device which can indicate an instantaneous state of the dynamic assignment between the cabinless vehicle used and the at least one piece of protective clothing of the at least one occupant.

[0035] As from Fig. 1 and 2As can be seen, the illustrated embodiment of a method 100 according to the invention for assigning at least one piece of protective clothing 5, which has at least one protective device 28, to at least one cabinless vehicle 3, which can activate the at least one protective device 28 during a journey, comprises a step S100 in which the at least one piece of protective clothing 5 and the at least one cabinless vehicle 3 exchange corresponding unique authentication information in a mutual static assignment by means of bidirectional wireless communication DK and store it in a step S110.In step S120, using the authentication information of the static assignment, at least one additional state variable of the at least one piece of protective clothing 5 and / or the cabinless vehicle 3 used is recorded at each start of a journey and evaluated in step S130 in the at least one piece of protective clothing 5 and / or the cabinless vehicle 3 used. In step S140, a dynamic assignment of the at least one protective device 28 to the cabinless vehicle 3 used is carried out for the current journey if at least one predefined condition is met when evaluating the at least one additional state variable.

[0036] This method can be implemented, for example, in software or hardware, or in a hybrid form of software and hardware, for example in the evaluation and control units 10, 20 of the in Fig. 2 The arrangement shown in 1 is implemented to assign at least one piece of protective clothing 5 to at least one cabinless vehicle 3.

[0037] As from Fig. 2 As can be further seen, the illustrated embodiment of the arrangement 1, which is configured to execute method 100, comprises at least one piece of protective clothing 5, 5A, 5B, 5C, which includes at least one protective device 28, and at least one cabinless vehicle 3, 3A, 3B, which, during travel, can activate the at least one protective device 28 of the at least one piece of protective clothing 5, 5A, 5B, 5C upon detection of an accident situation. The at least one cabinless vehicle 3, 3A, 3B has a first communication device 14, and the at least one piece of protective clothing 5, 5A, 5B, 5C has a second communication device 24, wherein the first communication device 14 and the second communication device 24 establish a wireless communication link between the at least one piece of protective clothing 5 and the at least one cabinless vehicle 3.A first evaluation and control unit 10 of the at least one cabinless vehicle 3, 3A, 3B and a second evaluation and control unit 20 of the at least one piece of protective clothing 5, 5A, 5B, 5C perform a mutual static assignment by means of a one-time exchange and one-time storage of corresponding unique authentication information via bidirectional wireless communication DK. Furthermore, the first evaluation and control unit 10 of the at least one cabinless vehicle 3, 3A, 3B and / or the second evaluation and control unit 20 of the at least one piece of protective clothing 5, 5A, 5B, 5C acquire and evaluate at least one additional state variable of the at least one piece of protective clothing 5 of the occupant and / or of the cabinless vehicle 3 used, at least before each journey, using the authentication information of the static assignment.In this process, the first evaluation and control unit 10 of the cabinless vehicle 3 used and / or the second evaluation and control unit 20 of the at least one piece of protective clothing 5 perform a dynamic assignment of the at least one protective device 28 to the cabinless vehicle 3 used for the current journey, if at least one predefined condition is met when evaluating the at least one additional state variable.

[0038] As from Fig. 2 As can be further seen, a protective arrangement in a protective garment 5, which in combination with a protective arrangement in a cabin-less vehicle 3 carries out the method 100 according to the invention, comprises at least one protective device 28, which can be activated during a journey by a cabin-less vehicle 3 in use, a communication device 24, which establishes a wireless communication connection with at least one cabin-less vehicle 3, and an evaluation and control unit 20, which conducts bidirectional wireless communication DK with the at least one cabin-less vehicle 3 via the communication device 24 and, in communication with the cabin-less vehicle 3, performs a one-time exchange and a one-time storage of corresponding unique authentication information and a mutual static assignment of the at least one cabin-less vehicle 3.The clothing-side evaluation and control unit 20 records at least one additional state variable of the at least one piece of protective clothing 5 of the occupant and / or the cabinless vehicle 3 used before each journey, using the authentication information of the static assignment, and evaluates this in communication with the cabinless vehicle 3 used, wherein the clothing-side evaluation and control unit 20 performs a dynamic assignment of the at least one protective device 28 to the cabinless vehicle 3 used for the current journey if at least one predefined condition is met when evaluating the at least one additional state variable.

[0039] As from Fig. 2 As can be further seen, a protective arrangement in a cabin-less vehicle 3, which in combination with a protective arrangement in a protective garment 5 carries out the method 100 according to the invention, comprises a communication device 14, which establishes a wireless communication connection with at least one protective garment 5, and an evaluation and control unit 10, which conducts bidirectional wireless communication DK with the at least one protective garment 5 via the communication device 14 and, in communication with the at least one protective garment 5, performs a one-time exchange and a one-time storage of corresponding unique authentication information and a mutual static assignment of the at least one protective garment 5.The vehicle-side evaluation and control unit 10 records at least one additional state variable of the at least one piece of protective clothing 5 of the occupant and / or of the cabinless vehicle 3 used before each journey, using the authentication information of the static assignment, and evaluates this in communication with the at least one piece of protective clothing 5 of the occupant, wherein the vehicle-side evaluation and control unit 10 performs a dynamic assignment of the at least one protective device 28 to the cabinless vehicle 3 used for the current journey if at least one predefined condition is met when evaluating the at least one additional state variable.

[0040] In Fig. 2 Two cabless vehicles 3A, 3B and three protective garments 5A, 5B, 5C, designed as jackets, are shown, each featuring a protective device 28 designed as an inflatable airbag. In the illustrated embodiment, the protective garments 5A, 5B, 5C are statically assigned to both the first cabless vehicle 3A and the second cabless vehicle 3B. Additionally, a first protective garment 5A and a second protective garment 5B are dynamically assigned to the first cabless vehicle 3A for the current journey. A third protective garment 5C is also dynamically assigned to the second cabless vehicle 3B for the current journey. Of course, other static and dynamic assignments of the protective garments 5A, 5B, 5C and the cabless vehicles 3A, 3B are also possible.

[0041] As from Fig. 2 As can be further seen, the protective clothing items 5A, 5B, 5C each have a non-volatile memory device 22, which in the illustrated embodiment is integrated into the respective evaluation and control unit 20. Alternatively, the non-volatile memory device 22 can be an external memory. The memory devices 22 of the protective clothing items 5A, 5B, 5C each store the first authentication information of the first cabless vehicle 3A and the second cabless vehicle 3B. The two cabless vehicles 3A, 3B each have a non-volatile memory device 12 in which the second authentication information of the three protective clothing items 5A, 5B, 5C is stored. This makes it possible for all three protective clothing items 5A, 5B, 5C to be dynamically assigned to both the first cabless vehicle 3A and the second cabless vehicle 3B for a journey. As shown Fig. 2 As can be further seen, the first piece of protective clothing 5A and the second piece of protective clothing 5B are dynamically assigned to the first cabless vehicle 3A for a current journey. The third piece of protective clothing 5C is dynamically assigned to the second cabless vehicle 3B for a current journey.

[0042] As from Fig. 2 As can be further seen, in the illustrated embodiment, the protective clothing items 5A, 5B, 5C and the cabinless vehicles 3A, 3B each have at least one sensor device 16, 26, which detects at least one additional state variable. In the illustrated embodiment, the sensor devices are each designed as inertial measuring units, each comprising a spatial combination of several inertial sensors, such as accelerometers and gyroscopes.

[0043] In the illustrated embodiment, the cabinless vehicles 3A, 3B each have a display device 18 which indicates an instantaneous state of the dynamic assignment between the cabinless vehicle 3 used and the corresponding protective clothing piece 5A, 5B, 5C of the at least one occupant.

[0044] In the illustrated embodiment, during the static assignment in step S110, initial authentication information for the individual protective clothing items 5A, 5B, 5C is stored in the two cabin-less vehicles 3A, 3B. Additionally, second authentication information for the two cabin-less vehicles 3A, 3B is stored in each of the three protective clothing items 5A, 5B, 5C.

[0045] Furthermore, a first additional state variable corresponds to an effective first acceleration information of the individual protective clothing items 5A, 5B, 5C, which is detected by the corresponding clothing-side sensor device 26. A second state variable corresponds to an effective second acceleration information of the corresponding cabin-less vehicle 3A, 3B, which is detected by the corresponding vehicle-side sensor device 16. Here, the individual protective clothing items 5A, 5B, 5C are dynamically assigned to the cabin-less vehicle 3A, 3B used for the current journey if the detected effective first acceleration information of the occupant's protective clothing item 5A, 5B and the detected effective second acceleration information of the cabin-less vehicle 3A, 3B are identical within a predefined tolerance range.Acceleration information, such as linear accelerations during acceleration or braking, as well as yaw rates during cornering of the cabinless vehicle 3A, 3B, can be recorded and evaluated. Since the cabinless vehicle 3A, 3B and the corresponding protective clothing 5A, 5B, 5C experience the same linear acceleration during acceleration or braking and the same yaw rates during cornering, the dynamic correlation can then be performed using cross-correlations between the total linear accelerations, a yaw rate vector, or component-wise. A corresponding coordinate system can preferably be horizontally aligned individually or jointly to align the orientation of the vehicle 3A, 3B (e.g., tilt, drift angle) and the occupant or the protective clothing 5A, 5B, 5C (position on the vehicle 3A, 3B).

[0046] In an alternative embodiment of method 100 (not shown), at least one additional state variable is evaluated to determine the distance between the at least one piece of protective clothing 5A, 5B, 5C and the cabless vehicle 3A, 3B used. The distance between the piece of protective clothing 5A, 5B, 5C and the vehicle 3A, 3B used can be estimated, for example, by evaluating the transmission time during wireless communication DK with specific coded signals. Alternatively, depending on availability and accuracy, the distance can be determined by evaluating the geographical positions of the vehicle and the piece of protective clothing, which can be acquired via a satellite system. In this case, the corresponding piece of protective clothing 5A, 5B, 5C can be assigned to the cabless vehicle 3A, 3B used for the current journey if the determined distance lies within a predefined range.

[0047] In a further alternative embodiment of method 100 (not shown), the at least one additional state variable corresponds to authentication information, which is optically visible or arranged as a readable transponder on the at least one piece of protective clothing 5A, 5B, 5C and is detected and evaluated by the vehicle-side sensor device 16. In this embodiment, the vehicle-side sensor device 16 comprises at least one optical sensor, which detects the optical authentication information on the piece of protective clothing 5A, 5B, 5C and forwards it to the vehicle-side evaluation and control unit 10 for evaluation. The optical sensor can, for example, be designed as a camera and detect a QR code or an infrared diode on the piece of protective clothing 5A, 5B, 5C.Alternatively, the vehicle-side sensor device 16 includes a reader for reading the authentication information from the transponder of the protective clothing item 5A, 5B, 5C. In this case, the corresponding protective clothing item 5A, 5B, 5C is dynamically assigned to the cabinless vehicle 3A, 3B used for the current journey if the detected or read authentication information corresponds to authentication information of a protective clothing item 5 statically assigned to the cabinless vehicle 3A, 3B used.

[0048] In another alternative embodiment of method 100 (not shown), the at least one additional state variable corresponds to an engine noise generated by the cabinless vehicle 3A, 3B, which is detected and evaluated by an acoustic sensor device 26 worn on the clothing. For this purpose, the sensor device 26 can include an acoustic sensor element, such as a microphone, which can detect the ignition timing of the vehicle 3A, 3B. The engine noises can then be evaluated, for example, by frequency analysis using a Fourier transform. By comparing the engine ignition times of the vehicles 3A, 3B within range of the microphone and determining the sound's travel time, a distance calculation is possible. For this calculation, a short and relatively constant transmission time for wireless communication is taken into account for non-time-synchronized end devices.In this process, the corresponding protective clothing item 5A, 5B, 5C is dynamically assigned to the cabinless vehicle 3A, 3B used for the current journey if the recorded and evaluated engine noises correspond to the condition data of the engine of the cabinless vehicle 3A, 3B used.

[0049] Depending on the sensor devices 16, 26 used, the automatic dynamic assignment of at least one piece of protective clothing 5A, 5B, 5C of an occupant to the vehicle 3A, 3B in use is carried out directly after the vehicle 3 is activated and before the journey begins, or within a time window after the journey begins. In the illustrated embodiment, the dynamic assignment of the corresponding piece of protective clothing 5A, 5B, 5C of an occupant to the vehicle 3A, 3B in use is also checked periodically or event-driven during the journey. This allows the driver to be notified of a detected dynamic assignment at the vehicle, giving them the opportunity to intervene. Furthermore, the periodic check of the dynamic assignment during the journey allows the driver to determine whether the corresponding piece of protective clothing 5A, 5B, 5C and its radio communication are still functioning.In addition, the driver can be warned visually and / or audibly by the display device 18 in the event of a malfunction.

[0050] The dynamic assignment of the corresponding protective clothing item 5A, 5B, 5C of the at least one occupant to the vehicle 3A, 3B in use is cancelled after the journey ends. In the illustrated embodiment, the end of the journey is detected after the vehicle stops, which is recognized by the unfolding of a stand, or after the vehicle 3A, 3B in use is deactivated.
