Description

The present invention relates to a method for disposing of motor vehicle occupant protection devices with a pyrotechnic igniter, according to the preamble of claim 1, and a device therefor according to the preamble of claim 12.

In modern motor vehicles occupant protection devices are increasingly installed in a large number of variants in order to achieve the best possible protection of the occupants in the event of an impact.

Such occupant protection devices may be, for example, airbags, belt tensioners or the like, which have a pyrotechnic igniter or actuator, as for example in the in the DE 198 27 427 A1 described vehicle occupant restraint systems or in which in the DE 197 29 226 A1 described airbag system for protecting an occupant of a vehicle is the case.

Due to various national regulations, there is a need to recycle end-of-life vehicles, used motor vehicles, accident new or used cars, etc. In the recovery of old vehicles or accident new or used cars, among other things, there is the problem that pyrotechnic igniter or actuators, which may be installed, for example, in airbags, belt tensioners or the like, either separately removed or even with them as a whole unit from the Motor vehicle must be removed before the vehicle can be disposed of. In addition, the recycling of all components should still be designed as inexpensively as possible.

To disarm pyrotechnic components after appropriate disassembly of trim parts, the connecting wires of the detonator or squibs made available and then triggered by applying a voltage, the igniter or pyrotechnic actuators, as for example in the DE 198 49 079 A1 is discussed. This procedure is particularly time-consuming and thus cost-intensive, especially with the rapidly increasing number of pyrotechnic detonators in the vehicles. An expansion of the pyrotechnic actuators ruled further, both because of the required time and associated cost and because of the associated at the same time risk of injury to the mechanics.

Accordingly, in the DE 198 49 079 A1 provided that the detonators are triggered together when an individually provided for this purpose, stored in the vehicle individual code signal is input from the outside and the test of the two individual code signals has been carried out to match positive. However, this procedure requires for each individual vehicle vehicle-specific, individual data to which initially only the respective vehicle manufacturer has access and which accordingly can provide only this vehicle manufacturer, so that a wide and at the same time low-cost recovery of end-of-life vehicles by professional vehicle recycler or disposers obstructs it becomes.

From the DE 196 37 677 A1 a method and a device for recycling airbag modules is known, brought in the after an impact event not ignited airbag modules in a security container for ignition and then dismantled together with already ignited modules that are incurred in the motor vehicle breakdown together. The case proposed safety container for subsequent ignition of not yet ignited pyrotechnic detonators or airbag modules in this case has at least five times the airbag volume and forms a closed space, which is closed by a tight-fitting door.

To ignite the airbag module, an ignition cable is connected, connected to a mounted in the safety container contact a door connector and stored on the ground, that the gas generator comes to rest on a built-steel plate. By closing the door, the electrical contacts are closed and the gas generator can be ignited safely by a mechanic. To carry out this complex process, however, a stationary, relatively large safety container is required, which leads to unacceptable costs and unnecessarily complicates or impedes the disposal of motor vehicles on a large scale on a broad front.

Furthermore, from the DE 197 53 058 C2 a method for disposing of pyrotechnic detonators and a disposal device for its implementation has become known in which a Entsorgungszündbefehl issued to an igniter or an interposed controller and the detonator is ignited.

From the DE 100 54 681 A1 It is known to initiate a forced release of an airbag via an external triggering device, wherein the series of triggering of several Aurbags is determined by a program stored in the triggering device or an airbag control program.

Another approach is that in the DE 101 13 099 A1 described method for disposing of an airbag and a for this hammered specified device. There, the airbag to be disposed of in a device for collecting gases or solids, which is to be arranged in front of the airbag in the installed position, unfold at its ignition. However, this approach is already connected because of the complex positioning of the device with considerable personnel costs, which inevitably entails correspondingly high costs. At the same time, this procedure can not be reasonably implemented in large-scale plants with the corresponding throughput in view of the future quantities of vehicles to be disposed of due to the high time requirement in practice.

Despite all the efforts and proposals discussed above, to provide cost-effective or simple as possible method for disposal of occupant protection devices, the issue of disposal of motor vehicles with such occupant protection devices remains largely unresolved today, since all of the above, discussed methods are not satisfactory in practice due to a variety of problems could prevail.

However, since it is already unacceptable for occupational and fire safety reasons, to give vehicles with intact pyrotechnic detonators in the cycle of disposal or scrapping and scrap recycling and also not only the number of vehicles to be disposed of, but at the same time the number of in a motor vehicle installed occupant protection devices continue to rise significantly and vehicle-specific vary according to the wishes of customers, so that the clarity on the number and location of the pyrotechnic detonator can be lost especially in the course of a vehicle life and an expansion of occupant protection devices due to the high risk of injury not responsible and also to is expensive, there remains the task of proposing a method for disposal of occupant protection devices with pyrotechnic igniter while avoiding the disadvantages discussed above, as well as to provide a device for this purpose en, which ensures a particularly simple, cost-effective and safe disposal.

This object is achieved in procedural terms by the features of claim 1 and in device-technical terms by the features of claim 12.

Here, a method for disposing of motor vehicle occupant protection devices with a pyrotechnic igniter, such as airbags, belt tensioners or the like, proposed according to the invention, wherein a Entsorgungszündbefehl is provided to a detonator upstream control unit and the detonator is ignited. It is provided for the first time that the control unit has a main memory, in which a Entsorgungszündprogramm is stored, by means of which a detonator, preferably all detonators together, is controlled and triggered / are.

Thus, for the first time, the possibility is created that motor vehicle occupant protection devices with pyrotechnic detonators or actuators can be controlled by vehicle manufacturers or cross-brand as well as within a vehicle product range of a manufacturer across all types and safely disposed of.

With the Entsorgungszündprogramm to be loaded into the memory of the controller Entsorgungszündprogramm both brand or manufacturer-spanning similarities and vehicle-typical, individual characteristics with regard to the number of installed in the vehicle to be disposed igniter, their type, their special address in the vehicle data bus, etc. are easily taken into account. In addition, it is thus possible to first of all detect and record all occupant protection devices installed in the vehicle, determine their address codes, address the respective addresses and compare and / or compare the data generated with databases stored in databases for the vehicle.

The well-known from the prior art mutual obstruction by special, vehicle and brand-specific Keycodes is thus avoided and it is offered for the first time a box-friendly alternative, with not only the vehicle manufacturers, but also quite generally the vehicle disposal a disposal of end-of-life vehicles and From accident-damaged new vehicles cost-effective, safe and can do quickly or efficiently.

It can be checked with the Entsorgungszündprogramm at the same time, for example, if all the pyrotechnic detonator or actuators were accidentally ignited in an accident, or if some of the pyrotechnic detonator installed in the vehicle to be disposed of remained ignited. These can then be targeted.

Similarly, the Entsorgungszündprogramm can check whether, for example, in a new vehicle to be disposed of or a used but not accidented vehicle still all detonators are intact and therefore preferably can be ignited together in a parallel ignition operation. In addition, can advantageously with the Entsorgungszündprogramm at the same time the ignition of the not yet ignited pyrotechnic actuators logged and a corresponding protocol can be generated so that a used or used or Used car recycler also appropriate evidence to prove the scrapping process can submit.

In this case, the Entsorgungszündprogramm must advantageously not necessarily be part of the normal, stored in the control unit of the vehicle occupant protection devices ECU program, but only when needed, so only in a specific vehicle disposal, for example, using existing diagnostic interfaces such as K-lines or so-called Can be downloaded to the vehicle occupant protection device control unit or in an airbag control unit so that it can then be executed there.

According to the present invention, it is provided that the Entsorgungszündprogramm, for example by means of a suitable mechanism, a correspondingly constructed circuit or a correspondingly designed routine, a backup function, which prevents accidental or undesired triggering of the fuze of an occupant protection device, such as an airbag or a belt tensioner , overrides. This advantageously makes it possible for the first time to circumvent the safety function implemented in some control units, in particular for airbag control units, against undesired triggering of the airbag, for example in the event of an unintended fault in the electronics, so that the airbag in question nevertheless deliberately tripped and then disposed of can be.

Further advantageous embodiments and aspects of the invention discussed above are the subject of the dependent claims.

Thus, it is provided in a preferred embodiment of the method according to the invention that the Entsorgungszündprogramm is downloaded by means of a diagnostic interface or the like in the control unit of the occupant protection device. This offers the advantage that interfaces already present in the vehicle, such as, for example, such diagnostic interfaces or so-called "K lines" or "CAN lines", are advantageously used for data transfer so that the Entsorgungszündprogramm be loaded from the outside into the control unit of an airbag can, so that in normal everyday operation of the motor vehicle advantageously no memory of the controller blocked and could not be accidentally called.

In addition, this procedure offers the further advantage that manufacturer-independent vehicle recycler can develop or further develop the Entsorgungszündprogramme to be used on a multi-vendor platform, so either the respective Entsorgungszündprogramm variant generated or a manufacturer-independent version of a general Entsorgungszündprogramms can be developed and used. This greatly facilitates the disposal of motor vehicles. In addition, it may be easier to comply with future regulations or guidelines in this way.

According to a further preferred embodiment of the method it is provided that the ignition of the motor vehicle in execution of the method "off" and the ignition key is deducted. This ensures that the ignition of the pyrotechnic actuators or detonators exclusively during the disposal process and thus can not be made accidentally in everyday operation or in any other operating situation of the motor vehicle.

According to a further preferred embodiment it is provided that windows, doors, tailgate and / or possibly sunroof or other openings of the motor vehicle are closed when the method is executed. This ensures in an advantageous manner that after ignition of the pyrotechnic igniter in the vehicle interior flying around fairings, panels, dust, particles, pyrotechnic residual powder or resulting combustion gases or the like can not escape from the vehicle interior and possibly pull surrounding mechanics or uninvolved persons affected. In addition, it requires in this way no separate detonation chamber, as proposed for example in the prior art.

In addition, elaborate detonation funnels or suction devices, as also discussed in the prior art, can be avoided. This helps accordingly to reduce the disposal costs and thus allows for the first time an inexpensive and at the same time efficient vehicle utilization.

In a further preferred embodiment of the method, it is provided that the motor vehicle is locked when the method is executed. This ensures that when igniting the pyrotechnic igniter in the vehicle to be disposed of any doors, trunk lid, windows or the like can be opened from the outside, not accidentally. This will ensure the security of the Disposal of motor vehicles commissioned mechanic significantly increased.

In a further preferred embodiment of the method, it is provided that a test system or a test adapter checks via the diagnostic interface before triggering the igniter, whether the vehicle is unoccupied. On the one hand, this offers the advantage that not only the Entsorgungszündprogramm is loaded into the main memory of the controller via the diagnostic interface, but a maintained for the duration of the corresponding disposal process section data connection between the motor vehicle or its data bus and a test system or a test adapter is maintained. In this case, all essential functionalities can be imaged in a test adapter, which is advantageously placed on the diagnostic interface and connected to it in a data-transmitting manner, so that there is no further connection between the vehicle to be disposed of or the pyrotechnic detonators to be ignited therein ,

Alternatively, if necessary, a connection can be provided via a data line to an extensive test system, if correspondingly more complex tests for collecting data of all kinds make sense. It is particularly advantageous in all variants that the check whether the vehicle is unoccupied, ensures that no persons or other living things are in the vehicle when the detonators are ignited, so that a threat to living beings, especially of humans, are excluded can. Such a check of the vehicle interior can be carried out, for example, via the seat occupancy control frequently contained in the vehicle in its seats or via ultrasound or otherwise operating room monitoring devices or so-called DWA's present in the vehicle.

According to a further preferred embodiment of the method, the test system or the test adapter checks via the diagnostic interface before triggering the detonator, whether windows, doors, possibly sunroof or tailgate or the like of the vehicle are closed and / or if the vehicle is locked. The achievable advantages correspond to those discussed above.

According to a further preferred embodiment, it is provided that the test system or the test adapter loads the Entsorgungszündprogramm in the main memory of the controller. This ensures that even when downloading the Entsorgungszündprogramms human sources of error remain excluded. This ensures a reliable and safe functioning of the method according to the invention.

According to a further preferred embodiment, it is provided that the Entsorgungszündprogramm is started by means of the motor vehicle remote control. This not only offers the advantage that the ignition of the pyrotechnic igniter from outside the vehicle can be done in due distance, but it is also ensured in turn advantageously that when you start the Entsorgungszündprogramms the ignition of the motor vehicle to "off" and set the ignition key is deducted because the one mechanic who triggers the ignition holds the key or the remote control in his hands.

The above-discussed object and its procedural solution is achieved in device-technical manner by the features of claim 12, as already mentioned above.

For this purpose, a device for disposal of motor vehicle occupant protection devices with a pyrotechnic igniter, such as airbags, belt tensioners or the like, proposed by means of a Entsorgungszündbefehl a detonator upstream control unit available and ignite the detonator, wherein for the first time continues to be proposed that the control unit having a main memory, in which a Entsorgungszündprogramm can be stored, by means of which an igniter, preferably all igniter is jointly controlled and triggered / are. The achievable advantages accordingly in synergetic manner with those achievable with the method according to the invention.

According to the invention, provision is made for a device, circuit or routine to be provided by means of which a safety function of the control device, which is intended to prevent unintentional triggering of the igniter, can be disabled by the disposal ignition program.

Further advantageous features or aspects in terms of device technology are the subject of the dependent claims.

Thus, it is preferably provided that a diagnostic interface is available, by means of which the Entsorgungszündprogramm is transferable to the control unit. Furthermore, a test system which can be connected to the diagnostic interface or a test adapter which can be connected there in a suitable manner is provided.

In a particularly preferred embodiment of the method according to the invention it is provided that the control unit of an airbag is designed or designed such that in his Memory (RAM) a program can be stored, which is able to target the squibs individually or all squibs together and thus bring them to trip. It is - as discussed above - a decisive advantage that this special ignition program is not part of the normal ECU program, but only when needed using an existing diagnostic interface (K-line / CAN) downloaded into the airbag control unit or is stored there and then executed. The following sequence is preferably provided:
A mechanic adapts a test system z. B. the test system TECH 2 of the applicant with respect to the vehicle to be disposed of. The mechanic selects the "Dispose of Airbag" service program. In addition, the mechanic switches off the ignition and pulls off the ignition key. Then the mechanic leaves the vehicle and closes the same with the central locking or the key. If any windows or roofs are still open, the mechanic drives the windows, for example, over the central locking and closes z. B. the trunk.

The test system then communicates via K line / CAN with the airbag control unit. The test system checks whether the vehicle is unoccupied and queries, for example, the seat occupancy control, an ultrasound room monitor or a DWA. The test system also checks to see if the vehicle is locked and the windows are raised, the roof is closed and the boot lid is closed. Now the test system loads the routine "dispose airbag" in the control unit and then executes this routine "dispose of airbag". In this case, all occupant restraint systems or airbags or belt tensioners, which had not yet been triggered, go off and the vehicle can be disposed of finally.

The invention discussed above will be explained in more detail below with reference to an exemplary embodiment with reference to the drawing. It shows:

1 An embodiment of a device according to the invention for the disposal of motor vehicle occupant protection devices.

In the only one 1 is an exemplary embodiment of a device according to the invention for the disposal of motor vehicle occupant protection devices, in particular an airbag disposal device 1 shown. The air bag disposal device 1 works with a detonator 2 for triggering an airbag 4 together. The detonator 2 is via electrical lines 6 respectively. 8th and other electronic components with a control unit 10 electrically connected. The control unit 10 is a dual-processor controller in the embodiment shown here by way of example 10 and accordingly has two processors 12 respectively. 14 on that as a dual processor 15 are summarized. The one processor 12 is designed as a backup microprocessor and receives data from a backup acceleration sensor 16 which can also be designed as a mechanical switch. The other processor 14 of the dual processor 15 is designed as a trigger microprocessor and receives data from a trigger acceleration sensor 18 which can absorb and process acceleration values in at least two directions, for example the x and y directions.

The in the control unit 10 included or integrated dual processor 15 also receives supplemental data from an additional acceleration front sensor 20 as well as another acceleration side sensor 22 ,

In the embodiment shown here between the igniter 2 of the airbag 1 and the core of the controller 10 namely the dual processor 12 and 14 switched, other electronic components can within the control unit 10 for example, on a there existing ignition circuit IC 23 be integrated, as shown here, or possibly also housed or integrated outside in a separate component.

A diagnostic bus 24 queries various devices of the motor vehicle and checks their status, such as the central locking 26 , the sunroof 28 , the windows 30 , the doors 32 or the trunk 34 , The diagnostic bus 24 stands for this with the dual-processor controller 10 for data transmission in connection. Furthermore, to the diagnostic bus 24 a conventional diagnostic test apparatus, the Applicant's diagnostic tester "TECH 2", a diagnostic calculator, a notebook or the like can be connected to perform diagnostic procedures, these additional devices being generally indicated by the reference numeral 36 should be symbolized. The diagnostic test device 36 may include a Entsorgungszündprogramm 38 load or in its diagnostic routines already included with the Entsorgungszündprogramm 38 in turn, for example, a routine 40 "Triggering the airbags" and a routine 42 "Unlock the fuse function" may have.

The disposal ignition program 38 can from the diagnostic test device 36 via the diagnostic bus 24 in the control unit 10 or directly into the dual processor 15 be downloaded. This is the backup microprocessor 12 the disposal primer routine 42 Transferring the backup function is transferred. In an analogous way becomes the trigger microprocessor 14 the disposal primer routine 40 Assigned "Airbag deployment" for execution.

The air bag disposal device 1 or their control unit 10 is in the variant shown here by means of the connections 44 and 46 with ground potential and continue by means of the connection 48 connected to the electrical system or the on-board voltage supply of the motor vehicle. Furthermore, it is a supplementary power source 50 , which may be formed adjustable, for example, provided that an electronic safety switch 52 fed.

The electronic circuit breaker or fuse switch transistor 52 stands with the backup microprocessor 12 in conjunction and is optionally via an optional resistor (not shown here) as well as a so-called "high side" driver or transistor 56 , in turn, from the backup microprocessor 12 is controlled, connected to the airbag. Furthermore, the second electrical connection line 8th the detonator 2 about a resistance 58 and the connection 46 connected to the ground potential as well as via a so-called "low side" driver or transistor 60 over the connection 44 connected to the ground potential, the "low side" driver 60 in turn, from the trigger microprocessor 14 is controlled. Here are the "high side" driver 56 and the "low side" driver 60 via a diagnostic element 62 , for example, a diagnostic operational amplifier, linked to the dual-processor controller 10 fed back.

The with in this variant on a Zündkreis IC 23 integrated electronic components and the fuse switch transistor 52 Built-up circuit serves to ignite the igniter 2 , who is here to exemplify the variety of fuses installed in the motor vehicle, to drive to diagnose this and the circuit breaker 52 to provide additional security against unwanted tripping. While the backup microprocessor 12 the electronic circuit breaker 52 turns on, the trip microprocessor switches 14 the high-side and low-side drivers or transistors 56 and 60 by. Thus, the triggering is done by two independent branches, in which the conditions for triggering must be fulfilled simultaneously, so that it triggers and thus to the explosion of the detonator or the squib 2 comes. The safety switch 52 and the ignition circuit IC 23 are in the variant shown here two separate components. The power source 50 supplies the diagnostic current for measuring the resistance of the igniter 2 , The associated voltage drop is through the diagnostic amplifier 62 amplified and to the trigger microprocessor 14 led to the condition of the detonator 2 or the squib (eg a) already triggered, or b) interrupted or triggered, or c) intact but not yet triggered).

The diagnostic bus 24 allows, for example, a diagnosis via CAN according to ISO 15 765 or via a so-called K-line according to ISO 9141, or the like.

The present invention thus proposes for the first time a method for disposing of motor vehicle occupant protection device with a pyrotechnic igniter. Such occupant protection devices may be, for example, airbags, belt tensioners or the like. Here, a Entsorgungszündbefehl is provided on a detonator upstream controller and detonated igniter. It is proposed for the first time that the control unit has a main memory, in which a Entsorgungszündprogramm is stored, by means of which a detonator, preferably all detonators together, is controlled and triggered / are. In addition, a device is given for this purpose.
