Abstract

The invention relates to a method for providing rescue-relevant information in which first of all the immediate imminence and/or occurrence of an accident is detected, whereupon a piece of detection information about the imminence or the occurrence of the accident is transmitted to at least one mobile rescue data transmission unit (5, 8) and the latter is put into a rescue mode upon receiving the detection information. In rescue mode, the at least one mobile rescue data transmission unit (5,8) sends a first piece of location information, denoting the location of the detection, continuously or at defined intervals of time. When a defined period of time after the detection has elapsed, a second piece of location information is transmitted from the vehicle (7, 9) to the at least one mobile rescue data transmission unit (5, 8) or is created by the latter itself, wherein the second piece of location information denotes the location of the vehicle (7, 9) at the time at which the second piece of location information is created and wherein the second piece of location information is sent continuously or at defined intervals of time in addition to the first piece of location information.

Description

Method and system for providing recovery relevant information

The invention relates to a method according to the preamble of claim 1 and a system according to the preamble of claim 11.

On the recommendation of the ADAC today it is often the case, the vehicle rescue with important card for a salvage information in an easily accessible external location, such as behind the sun visor of the driver where appropriate to participate ¬ lead. The rescue map depicts critical vehicle sites for the emergency services to help them recover from the vehicle. Attention should be paid to salvaging not only the avoidance of additional hazards, which emanate from not yet triggered airbags, but also the increasingly used in modern vehicles high-strength steels that make it difficult to cut the vehicle at the appropriate places. Also to be considered by the rescue workers is the drive technology of the accident vehicle, since combustion engine fuels make other Sicherheitsvorkehrun ¬ conditions necessary as the batteries of an electric or hybrid vehicle. However, before any recovery of the vehicle occupants can be made, the forces must be informed about the accident and the exact location of the accident. This can be done, for example, by means of an automated emergency call known from the prior art

("ECall"), which is automatically sent by the vehicle when an accident is detected. Seeing European Union specifications for an "eCall" require a positional accuracy of

± 150 m in 95% of all cases. Due to this inaccuracy, the recovery of injured persons, especially when off road in unclear terrain, delayed.

In this context, DE 10 2009 709 Al discloses a method for improving and validating a position determination. The position of the own vehicle is adjusted by means of vehicle-to-X communication with position data of adjacent vehicles, possibly improved and vali ¬ diert. As a communication unit can serve, for example, designed for wireless communication key of the vehicle. The thus validated position may be included as Posi ¬ tion information in an automated emergency call.

From DE 10 2008 043 001.3 a locating aid for emergency services is also known. An injured vehicle continuously or regularly emits a locating signal, which is received by the emergency services. The locating signal thus supplements the position information contained in an automated emergency call. In order to find a e.g. For example, the emergency services can activate and control the vehicle's headlights, horn, and interior lighting by means of a radio link to the vehicle. In addition, one-time positioning aids in the form of

Flares are activated. Likewise, it is the task force on the location system described possible, a wireless query of the status of critical vehicle components, such as airbags, fuel tank and batteries.

In DE 10 2009 015 513 AI a locating signal for emergency services is described, which also facilitates finding ei ¬ nes accident vehicle and accelerates the recovery of the vehicle occupants. The transmission of the locating signal is triggered by a trigger event, wherein the trigger event can be both the detection of an accident and the receipt of a search signal of a rescue force. In order to transmit the locating signal redundant, DE AI describes 10 2009 015 513, not only a valve disposed structurally fixed in the vehicle module for generating and sending the locating signal, but in addition also mobile a ¬ units (for example, radio communication capable ignition key, mobile phone, GPS), which transmit the locating signal entspre ¬ accordingly. Previously, the data to be sent from the vehicle to the mobile unit wired or wireless ¬ carry. The location signal may also parallel or time ¬ on consecutively from several emergency units (mobile or fixed units located in the vehicle) to different communication paths (for example, WiFi, WiMax ®, Bluetooth ®, ZigBee or cellular) to be sent. In addition, the rescue services can request additional information, such as a vehicle-specific rescue manual, from the respective emergency call unit.

However, the methods and devices known from the prior art are disadvantageous for various reasons. So they are always up to a certain proportion of still functional vehicle modules or a handene before ¬ power supply in the accident vehicle reliant sen. Likewise, it is not taken into account that an accident vehicle can send incorrect data as a result of the accident or that incorrect data can be transmitted to a mobile unit, which is then passed on by it. Especially if these data are position data of the vehicle, the salvage can be delayed by a not insignificant period of time.

The invention is therefore based on the object to propose a verbes ¬ sertes method or an improved system, which allows a transfer rescue relevant information while avoiding the disadvantages known from the prior art.

This object is achieved by the method for providing recovery-relevant information according to claim 1 and the system for providing recovery-relevant information according to claim 11.

In accordance with the method according to the invention for providing information relevant to recovery, in which an immediate imminence and / or occurrence of an accident event is first detected, whereupon a detection information about the imminence or occurrence of the accident event is transmitted to at least one mobile salvage data transmission unit and these are transmitted Receiving the detection information is placed in a salvage mode, is transmitted from the at least one mobile salvage data transfer unit in salvage mode continuously or at defined time intervals, a first location information and also a response to a Abfragenig ¬ nal, a reset signal and / or an activation signal made possible. The first location information designates the location of the detection of the imminent occurrence or the occurrence of the accident event and is transmitted from a vehicle to the at least one mobile salvage data transmission unit or created by the latter itself. Upon receipt of the interrogation signal of a salvage data retrieval unit, retrieval-relevant information retrieved by the at least one mobile salvage data transfer unit is transmitted. The inventive method is characterized in that after a defined period of time after the detection of the imminent occurrence or occurrence of the accident event, a second location information from the vehicle to the at least one mobile Rettungsdatenübertragungsein- unit is transmitted or created by itself, the second location information the location of the vehicle at the time of creating the second location information be ¬ draws and wherein the second location information from the min ¬ least one mobile rescue data transmission unit to ¬ addition to the first location information is transmitted continuously or at defined time intervals. Compared to the generic method known from the prior art, there is thus the advantage that not only the position data of the accident location are sent, but additionally the position data of that location at which the vehicle is a defined period of time after the occurrence of the accident event. This ensures the ¬ that even with vehicles involved in accidents, for example, agreements as a result of the accident is still high speed of the roadway and only off the road in difficult terrain, possibly with dense vegetation, come to Ste ¬ hen, a local Information Is available, which designates the current vehicle location. This speeds up that Locating the vehicle by the recovery forces and allows a faster supply of the vehicle occupants. This is a great advantage, especially with regard to accident events associated with serious injuries to the vehicle occupants. The defined time period, the second location information is created after the lapse may, for example, s be ¬ wearing 20th It should be of the order of magnitude of the period from the agreement of a vehicle from the lane to its final and safe stoppage. In addition, by retrieving rescue-relevant information only in salvage mode, unauthorized retrieval of this data by unauthorized persons is prevented.

Preferably, it is provided that the generated at least one mobile rescue data transfer unit continuously or in de ¬-defined time intervals or upon receipt of the activation signal optical and / or acoustic signals. Thus, it is possible to find the injured vehicle even in unclear terrain, as by means of the optical or acoustic signals targeted the attention of the salvage forces can be energized. Optical signals are very effective, especially in the dark, while akus ¬ tical signals unfold their particular advantages regardless of the lighting conditions, especially in difficult to see terrain. Conceivable here are, for example, special Blinksig ¬ signals or siren noises. These signals can be generated kontinuier ¬ Lich or at certain intervals, whereby the brightness can be determined at the scene of the accident by means of any existing lighting sensors at first and is then decided based on this information, whether a use of the optical signals in the circumstances makes sense. Provided that the signals are activated by means of an exter ¬ NEN activation signal concerns except ¬ which the advantage that any jammed or in the vehicle movement disabled persons are not exposed over the period until the arrival of the rescue forces the acoustic or optical signals. Send the activation signal as ¬ at the recovery forces by means of a Bergungsdatenabfrage- unit when they arrive on the scene and does not find the vehicle. An additional advantage of activating by means of an activation signal is that a possibly exclusively battery-operated mobile salvage data transmission unit does not exhaust its energy reserves before the recovery forces arrive at the scene of the accident.

In a further preferred embodiment, it is provided that the recovery-relevant information is one or more elements from the group

 - number of passengers,

 - names of passengers,

 - age of vehicle occupants,

- VIN, in particular vehicle identification number of VIN,

- name of the rescue guideline to be used,

 - Color of the vehicle,

 - make of the vehicle,

 - severity of the accident,

 - type of accident event,

 Vehicle speed when the accident occurs,

- Direction of travel when the accident occurs and - are the official license plate of the vehicle. On the basis of the data on the vehicle occupants and on the circumstances of the accident, this information allows both a quick assessment of the medical preparations to be made and, on the basis of the vehicle information, a planning of the rescue measures beforehand. Overall, the recovery process is accelerated and injured persons can be helped faster and better. Based on the names of the vehicle occupants, these may be easier to identify and inform relatives.

The method is preferably characterized in that a first portion of the recovery-relevant information sent by the at least one mobile recovery data transmission unit is permanently stored in the at least one mobile salvage data transfer unit and a second component upon detection of the immediate imminence or occurrence of the accident event from the vehicle to the at least one mobile salvage data transmission unit is transmitted. This does not need the event, event ¬ Un is transmitted to the mobile recovery data transmission unit within a short time a large amount of data on the occurrence. With regard to possibly resulting in severe damage to the vehicle and the Fahr ¬ zeugkomponenten associated with the accident event, the transmission of recovery-related information should be kept as short as possible, so as not to be canceled due to accident. Especially geeig ¬ net tenübertragungseinheit for a permanent storage in mobile Bergungsda- include data about the driver and the vehicle. It is also conceivable, a part of the mountain ¬ ungsrelevanten information already upon boarding, or if necessary even before departure to the mobile recovery data transfer unit to transmit.

According to another preferred disclosed embodiment of the invention, it is provided that a is seen ¬ fixedly provided in a vehicle at ¬ parent stationary rescue data transfer unit which, at least partially identical bergungsre ¬ information relevant as the at least sends a mobile rescue data transfer unit. Thus, it is possible to provide the recovery-relevant information redundant. Since it is possible as a result of an accident event that the mobile or the stationary salvage data transmission unit will be damaged and thus become inoperable, rescue-related information can still be made available in these cases due to the redundancy.

It is expediently provided that no further first and second location information items are transmitted by the at least one mobile salvage data transmission unit and / or the stationary salvage data transmission unit upon receipt of the interrogation signal and / or the reset signal, wherein the reset signal is transmitted by the vehicle or sent by the salvage data interrogation unit and terminates the mountain ¬ ungsmodus and wherein the reset signal is transmitted from the vehicle, in particular after a certain period of time after the detection of the immediate imminence of the accident event, if followed within the predetermined time interval no detection of the accident event. Thus ¬ remote mobile or stationary Bergungsdatenübertra- supply unit receives an interrogation signal that triggers the sending of retrieval of relevant information may excluded thereof will be gone, that the recovery forces have already arrived at the vehicle and there is no more Ortsinforma ¬ tions be sent. Upon receipt of the reset signal also no further location information is sent and also the salvage mode is terminated, whereby no recovery-relevant information can be queried more. This is particularly advantageous if several vehicles are involved in an accident event. Once a vehicle is found and all salvage-related data retrieved by this vehicle, rescue mode, the corresponding recovery data retrieval unit can complete ¬ the order not to disturb the search more vehicles and the visits to the salvage relevant information of the other vehicles. If the recovery mode is activated upon detection of an imminent crash event results in the further advantage that the vehicle can stop the recovery mode again automatically when entering no actual accident ¬ event within a certain period of time. In this case, it is assumed that the identification of the imminent occurrence of the accident event was a misdetection. The length of time of the specific period of time may be, for example, 5 s. You should predict the ability of the vehicle before handenen ¬ accident detection means, an imminence of Un ¬ event, event for a certain period, be coordinated.

Moreover, it is advantageous that prior to sending the ers ¬ th and the second location information and the recovery information relevant at least one mobile salvage from the data transmission unit via a communication medium ¬ procedure, in particular by means of a CSMA method Is (Carrier Sense Multiple Access), check whether the proposed for transmission channel bie ¬ tet enough free bandwidth. This results in the advantage that it is ensured that a trouble-free transmission of information at the current time is even possible. If the channel intended for transmission is occupied, another channel can be selected or the transmission of the information can be delayed until the channel again offers sufficient free bandwidth.

Furthermore, it is advantageous that the first and the second location information and the recovery-relevant information are not sent from the at least one mobile salvage data transmission unit or are sent with a defined time offset if the at least one mobile salvage data transmission unit contains the first and / or the second location information or salvage-relevant information is received, which are transmitted from the stationary salvage data transfer unit. This prevents both salvage data transmission units from transmitting at the same time, superimposing their data signals and being no longer evaluable. Since the stationary salvage data transfer unit usually has more powerful antennas and larger energy reserves, the stationary salvage data transfer unit is given preference if both salvage data transfer units are functional. Likewise, however, is also an exclusive or time ¬ Lich prioritized transmission means of the mobile Bergungsdate- nübertragungseinheit possible if the stationary salvage data transmission unit information of mobile salvage receives data transmission unit. Sending with a time offset also reduces redundancy in the information tion transmission, since the information is sent from both salvage data transmission units.

Moreover, it is preferred that at least one mo ¬ bilen rescue data transfer unit and / or the statio ¬ ary recovery data transmission unit, an automated emergency call is of the one-time or continuous ¬ ously or at defined time intervals transmitted, in particular by means of a mobile radio connection, to an interrogation signal or a reset signal is received becomes. Thus, a so-called "ECall", known per se from the prior art, is also sent, which assigns an emergency event to the sent location information can also be transmitted over the cellular link, which gives the emergency center immediately an accurate picture of the accident situation and can initiate appropriate recovery measures.

Advantageously, it is provided that at least one mobile rescue data transfer unit and / or the stationary retrieval data transmission unit sending a individu ¬ elle identification designation from the said individual identification name for individually addressing interrogation signals or reset signals to the used at least one mobile rescue data transfer unit and / or the stationary retrieval data transmission unit becomes. This results in the advantage that in case of un ¬ events with multiple vehicles individual query signals can be sent or the received location information is assigned to an individual vehicle can. Especially when sending a reset signal can be so ¬ with prevent the recovery mode Bergungsda- tenübertragungseinheit a not yet recovered the vehicle is stopped.

The invention further relates to a system for providing recovery-relevant information, which is particularly suitable for carrying out the method according to the invention. The system according to the invention comprises accident detection means for detecting an imminent occurrence and / or occurrence of an accident event, at least one mobile salvage data transmission unit for transmitting a first and a second location information as well as rescue-relevant information. The system also includes at least one recovery data interrogation unit for transmitting a query ¬ signal and / or a reset signal and / or a Akti ¬ vierungssignals to the at least one mobile Bergungsdate- nübertragungseinheit as well as for receiving the first and the second location information and the recovery information required. The detection means transmit detection information to the at least one mobile rescue data transfer unit upon detection of the imminence of immediate and / or the occurrence of the event, event ¬ Un. The at least one mobile salvage data transfer unit switches to a salvage mode upon receipt of the detection information. In the recovery mode, sends the at least one mobile Bergungsda- tenübertragungseinheit the first location information kontinuier ¬ Lich or in defined time intervals, and responds to the interrogation signal, the reset signal and the activa ¬ approximate signal. The first location information designates the location of the detection of the imminent occurrence or occurrence of the accident event, wherein a vehicle is the first Location information to the at least one mobile salvage data transmission unit transmitted or this the first place ¬ information itself created and the at least one mobile salvage data transmission unit sends to the query request ¬ nal requested recovery information. He ¬ invention contemporary system is characterized in that after a defined period of time after the detection of the immediate imminence or occurrence of Unfallereig ¬ Nisses the vehicle a second location information to the min ¬ least a mobile rescue data transfer unit ¬ averages or this second location information itself he ¬ represents, wherein the second location information the place of Fahr ¬ zeugs at the time of creating the second Ortsinfor ¬ mation and wherein the at least one mobile rescue data transmission unit transmits the second location information ¬ addition to the first location information continuously or at defined time intervals , The system according to the invention thus comprises all the devices necessary for carrying out the method according to the invention and enables reliable manner transmitting the current location information of the vehicle and a ¬ transmitting recovery data relevant. This results in the advantages already described.

It is preferably provided that the at least one mobile salvage data transmission unit has a vehicle power supply independent power supply and a device from the group

 - mobile phone,

 - Smartphone,

 - mobile navigation device,

- avalanche search device, - accident finder and

 - radio-enabled vehicle key

is and in particular includes additional sound and / or light means which are activated upon receipt of the activation signal. Such devices are already common and widely used and also often have in their basic equipment form (such as in the case of a smartphone) on the necessary means to be used as a mobile recovery data transmission unit in the context of the invention. What is needed is often only a geeigne ¬ tes computer program that runs on the devices. In the case of using, for example, a radio-enabled vehicle key as a mobile recovery data transmission unit, additional sound or lighting means can be a useful supplement. As lamps here are, in particular LEDs, as they have a compact design aufwei ¬ sen and high luminosity only a small Energiebe ¬ can have.

Furthermore, it is preferable for the detection means to be an environment detection device and / or an airbag sensor and / or an impact sensor. An airbag sensor is provided in all vehicles today and is therefore suitable without additional effort or additional costs as a detection means for detecting an accident event. Also, special impact sensors are already available as standard in many vehicles, whereby they can be used without additional effort or expense in the context of the invention. Surrounding detection devices such as radar sensors or cameras are present at least in many luxury class vehicles and increasingly also in middle class vehicles. The aforementioned radar sensors or cameras are suitable due to their orientation in the direction of travel and their principle of action comparatively good for detecting the imme ¬ diate impending occurrence of an accident event. However, it is also conceivable to use other suitable environmental sensors such as lidar sensors.

Moreover, it is advantageous that the recovery data include at least one mobile transmission unit, the stationary retrieval data transfer unit, the vehicle and the Bergungsdaten- interrogation unit communication means based on at least ei ¬ ner of the following types of connection:

 WLAN connection, in particular according to IEEE 802.11,

 ISM connection (Industrial, Scientific, Medical Band),

- Bluetooth ® connection,

 - ZigBee connection,

 - UWB connection (Ultra Wide Band),

- WiMax ® (Worldwide Interoperability for Microwave Access)

 - mobile connection,

 Infrared connection and

 - wired connection.

The connection species listed here offer different benefits, depending on the type, wavelength and used Datenpro ¬ Protocol. So some of these connection types eg allow a relatively high data transfer rate and egg ¬ nen relatively fast connection, others point ¬ against are largely very well around to Datenübertra ¬ supply to obstructions. The combination and simultaneous or parallel use of several of these connections There are further advantages, since it is also possible to compensate disadvantages of individual types of connection.

Furthermore, it is preferred that the at least one recovery data query unit comprises at least one directional antenna. This has the advantage that when Unfallereig ¬ Nissen, a direction-of a received signal can be performed with a plurality of vehicles involved in accidents, which are optionally concealed in difficult terrain. Particularly with regard to possible inaccuracies in the transmitted location information, this makes it possible to further accelerate the finding of an accident vehicle. In addition, a single salvage data transmission unit can thus be specifically addressed or queried even without an individual identification name.

Furthermore, the present invention relates to a Verwen ¬ tion of the method for providing recovery-relevant information in a motor vehicle.

Further preferred embodiments of the invention will become apparent from the dependent claims and the following description of an embodiment with reference to figures.

It shows

1 shows schematically a first embodiment of the system according to the invention and

Fig. 2 shows schematically another, particularly cost-effective

From the management form of the system according to the invention and Fig. 3 is a flowchart illustrating the individual Abiauf ¬ steps of a possible imple mentation of the method according to the invention.

The system exemplified in Fig. 1 for providing ¬ position retrieval of relevant information includes stationary recovery data transmission unit 1, which transmits by means of external antenna 2 and receive information, the GPS unit 3, the vehicle communication interface 4, mobile rescue data transfer unit 5 and recovery data retrieval unit 6. Stationary recovery data transmission device 1, External antenna 2, GPS unit 3 and vehicle communication interface ¬ point 4 are permanently installed in motor vehicle 7. Mobile salvage data transmission unit 5 is executed as a smartphone ¬ and is recognized at the start of the vehicle interface ¬ interface 4 via an activated Bluetooth connection. Recovery-relevant information can be transmitted from vehicle 7 to mobile salvage data transmission unit 5 via the Bluetooth connection. Outside of

Motor vehicle 7 salvage data retrieval unit 6 communicates by means of an ISM connection with mobile recovery data transmission unit 5 and stationary salvage data transmission unit. 1

In the memory of stationary data transmission recovery unit 1, the identifier of the to be used rescue guide, the color of the vehicle 7 and the vehicle ¬ brand and type of vehicle are factory already been registered. The registration number of the vehicle 7 is manually eingege ¬ ben by the driver and is also fixed in the memory of stored transfer unit Bergungsdatenü-. 1 When starting to drive determined vehicle 7 by means of a known seat occupancy direction, how many occupants are in vehicle 7 and transmits this information to stationary rescue data transfer unit 1. In addition, are transmitted every fixed ge ¬ stored in stationary rescue data transfer unit 1 information on to mobile rescue data transfer unit 5 at each ride, where this information is stored so long until the smartphone receives new information at the start of the next trip, or receives the same information again.

The current vehicle position and the current Fahrzeugge ¬ speed are GPS unit 3 and the wheel speed sensors (not shown) while constantly vehicle 7 ER- construed, however, only upon detection of the occurrence of a Un ¬ event, event mobile to stationary rescue data transfer unit 1 and rescue data transfer unit 5 over ¬ mediates. An accident event is detected by a pre ¬ given limit exceeding negative acceleration by means of impact sensor 17.

Upon the occurrence of the accident, the vehicle now ¬ position are transmitted in the form of the first location information and the vehicle speed wired to stationary rescue data transfer unit 1 and by means of a Bluetooth connection to mobile rescue data transfer unit. 5 Recovery data transmission unit 1 sends as ¬ raufhin an emergency signal via a cellular connection, which holds the detected during the accident GPS position ¬ ent. Mobile salvage data transmission unit 5 also sends an identical emergency signal by means of a mobile radio connection. After expiry of a period of 5 s, when vehicle 7 has come to a standstill after the accident, the current position is again detected and transmitted again to stationary rescue data transmission unit 1 and mobile rescue data transmission unit 5. These now each have the GPS position of the accident event (first Ortsinformati ¬ on) and the current GPS position in the form of the second location information.

As soon as the recovery forces arrive at the scene of the accident, they use the first and second location information received from salvage data query unit 6 to determine the position of the crashed vehicle and send an interrogation signal by means of a WLAN connection which is received both by stationary salvage data transmission unit 1 and by mobile salvage data transmission unit 5. Since the smartphone receives the location information sent from stationary salvage data transmission unit 1, the smartphone recognizes that stationary salvage data transmission unit 1 is still functional despite the accident event. Therefore, mobile rescue data transfer unit 5 waits to send a response comprising the requested bergungsrele ¬ information relevant to salvage data retrieval unit 6 a short time in order not to interfere with the signals sent from stationary rescue data transfer unit 1 salvage relevant information. Recovery data retrieval unit 6 thus receives two independent signals, making the mountain ¬ ungsrelevanten information is particularly reliable übertra ¬ gen.

Fig. 2 shows another from the guide form erfindungsge ¬ MAESSEN system, which is opposite to that shown in Fig. 1 shown System is considerably less expensive because they vehicle side ungsdatenübertragungseinheit 8, GPS unit 16 and driving ¬ persuasive communication interface 12 includes only a simple mobile phone integrated mobile mountain. Fahrzeugkommuni ¬ cation-interface 12 has a respective kabelge ¬ Thematic communication connection to the airbag sensor 13 to the GPS unit 16 and mobile rescue data transfer unit 8. Thus, mobile rescue data transfer unit 8, GPS unit 16, and airbag sensor 13 via the vehicle communication interface 12 communicatively coupled. Salvage data retrieval unit 14 is located outside of vehicle 9 at the salvage forces and does not incur any additional costs when procuring vehicle 9. Upon detection of an accident event by airbag sensor 13, airbag sensor 13 transmits corresponding detection information to mobile salvage data transmission unit via communication interface 12 8. At the same time, GPS unit 16 transmits a first position information, which corresponds to the location of triggering of airbag sensor 13, to mobile rescue data transmission unit 8. Thereafter, mobile rescue data transmission unit 8 automatically transmits an emergency call via a mobile radio network (indicated by mobile masts 10, 10 ', 10'') to emergency center 11. Emergency Center 11 receives the emergency call and can make a first location of mobile salvage data transmission unit 8 via the mobile network. Currency ¬ rend sends its mobile recovery data transmission unit 8 which is connected in a recovery mode due to the detection information, via Bluetooth continuously the first location information. The recovery forces arriving at the scene of the accident have rescue data retrieval unit 14 with directional antenna 15, with which they can request another and as required make more accurate location of mobile salvage data transmission unit 8 based on the Bluetooth signal.

Fig. 3 shows in the form of a flow chart a possible sequence of the method according to the invention. In step 31 de- tektieren a stereo camera and a Rardarsensor the fast ¬ le approaching an obstacle. Due to the current vehicle speed and the remaining braking distance, he is ¬ known that an accident can no longer be prevented and imminent. A corresponding detection information is output in step 32, a mobile recovery file transfer unit and a stationary salvage data transfer unit. Upon receipt of the detection information, both the mobile salvage data transmission unit and the stationary salvage data transmission unit switch to salvage mode in step 33. In the following step 34, the vehicle transmits a first location information created by means of a GPS unit to both recovery data transmission units. Both recovery data transmission units send an automated emergency call ("ECall") to an emergency call center in step 35. The parallel transmission of the emergency call generates a redundancy of the information transmission, which is particularly advantageous in the case of accident events, since critical information is transmitted here. In addition, since the recovery data transmission units have been put into recovery mode in step 33, they periodically transmit the first location information via an ISM band (Stationary Recovery Data Transfer Unit) or a WLAN (Mobile Recovery Data Transfer Unit) band and respond to the reception of polling signals , Reset signals and activation signals within a period of time of 5 s after detection of the imminent occurrence of the accident event, no actual occurrence of the accident event is detected in step 36. It is therefore ge ¬ concluded that the detection of the immediate imminence of an accident event was a false detection, and in

Step 37 transmits a reset signal from the vehicle to both the mobile salvage data transfer unit and the stationary salvage data transfer unit. The two salvage data transfer units thus switch back from the salvage mode to the normal mode in which they do not respond to interrogation signals, activation signals or other reset signals. Also, they do not send any further location information. In step 38, on the other hand, after 1 second has elapsed, an actual occurrence of the accident event is detected by means of a crash sensor. Accordingly, no reset signal is transmitted to the salvage data transmission units and they remain in salvage mode. After a further period of time (15 seconds) has passed in step 39, it can be assumed that the vehicle has come to a standstill, even if it has traveled at high speed before the accident. In the following step 40, therefore, a second location information is detected and transmitted to the salvage data transmission units. These now transmit in step 41 both the first location information and the second location information at periodic intervals over a WLAN frequency or an ISM band. Before sending, both units check by means of a communication bearer test procedure whether the channel intended for transmission offers sufficient free bandwidth. In addition, since the mobile salvage data transmission unit receives location information of the stationary salvage data transmission unit, it recognizes that it still has stationary salvage data transmission unit. is capable of transmitting and transmitting with sufficient time delay to the information sent by the stationary recovery data transmission unit to avoid overlaying the transmitted information. After the recovery forces have arrived at the scene of the accident and send an interrogation signal for interrogating the recovery-relevant data by means of a salvage data interrogation unit, the salvage data transmission units send the recovery-relevant data stored in them in response to receipt of the interrogation signal in step. In this case, too, the mobile salvage data transmission unit transmits with a time offset to the stationary salvage data transmission unit in order to avoid a signal overlay. After the recovery forces have retrieved all available recovery-relevant data, in step 43 they send a reset signal by means of the salvage data retrieval unit to terminate the salvage mode of the salvage data transfer units.
