Abstract

An emergency call system for vehicles sends an automatic emergency call in the event of danger, accident or breakdown, that can be clearly read at a signalling station, or announced by a loudspeaker. The simultaneous transmission of the vehicle position and number of persons in the vehicle allows important information to be immediately transmitted, for example in the case of an accident. Various vehicle systems, for example an air bag system, an anti-theft alarm system, temperature sensors and vehicle controllers can be used as signal generators. The location of the vehicle is given by a locating/navigating device on board the vehicle, making the taking of bearings unnecessary.

Description

Notrufeinrichtung für ein Fahrzeug Emergency call device for a vehicle
Stand der Technik State of the art
Die Erfindung geht aus von einer Notrufeinrichtung für ein Fahrzeug, insbesondere ein Kraftfahrzeug, nach der Gattung des Hauptanspruchs. Es sind schon Notrufeinrichtungen bekannt, die beispielsweise als Notrufsäulen an Autobahnen oder viel befahrenen Bundesstraßen stationär aufgestellt sind. Bei einem Verkehrsunfall oder einer Autopanne muß der Fahrer bis zur nächsten Notrufsäule unter Umständen eine weite Strecke zurücklegen, um Hilfe herbeizurufen. Dadurch geht viel unnötige Zeit verloren, die gerade bei einem Verkehrsunfall mit verletzten Personen sehr kostbar ist. The invention relates to an emergency call device for a vehicle, in particular a motor vehicle, according to the preamble of the main claim. Emergency call devices are already known, which are stationary, for example, as emergency call pillars on motorways or busy federal roads. In the event of a traffic accident or a car breakdown, the driver may have to travel a long way to the next emergency call station to call for help. As a result, a lot of unnecessary time is lost, which is particularly valuable in a traffic accident involving injured people.
Weiterhin ist ein Mobiltelefon bekannt, das in einem Kraftfahrzeug betreibbar ist. Das Mobiltelefon ist über Funk mit einer Empfangsstation verbunden, über die unter anderem in einem Notfall Hilfe herbeigerufen werden kann. Das Mobiltelefon ist vom Fahrer oder einem Mitfahrer manuell zu betätigen. Furthermore, a mobile phone is known that can be operated in a motor vehicle. The mobile phone is connected via radio to a receiving station, which can be used to call for help in an emergency, among other things. The mobile phone must be operated manually by the driver or a passenger.
Die Erfahrung zeigt, daß beispielsweise bei einem Unfall eine wenig geübte Person das Mobiltelefon in der Aufregung nicht bedienen kann, sei es auch nur, daß ihr nicht die entsprechende Notrufnummer einfällt, oder daß die Person nur unvollständig Angaben machen kann. Bis zum Herbeirufen der notwendigen Hilfe kann gegebenenfalls viel Zeit vergehen. Insbesondere kann bei einem schweren Unfall mit Verletzten und bewußtlosen Personen ein schneller Notruf kaum abgegeben werden. Lebensrettende erste Hilfemaßnahmen verzögern sich dadurch. Experience shows that, for example, in the event of an accident, a person who is not very experienced can not use the mobile phone in the excitement, be it only that they cannot think of the corresponding emergency number or that the person can only provide incomplete information. It may take a long time to get the necessary help. In particular, a rapid emergency call can hardly be made in the event of a serious accident involving injured and unconscious people. This saves life-saving first aid measures.
Weiterhin ist bekannt, daß von einem in einem Kraftfahrzeug befindlichen Notfunkgerät ein manuell ausgelöster Notruf aussendbar ist. Dieser Notruf wird von stationären Empfangsstationen empfangen. It is also known that a manually triggered emergency call can be emitted from an emergency radio device located in a motor vehicle. This emergency call is received by stationary receiving stations.
Durch Peilungen mit stationären Peilgeräten muß der Standort des Notrufers ermittelt werden, um ihm helfen zu können. Das erfordert sehr viele über das Land verteilte Peilgeräte. The location of the emergency caller must be determined by bearing with stationary direction finders in order to be able to help him. This requires a lot of direction finders across the country.
Vorteile der Erfindung Advantages of the invention
Die erfindungsgemäße Notrufeinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß ein Notruf automatisch ausgelöst wird. The emergency call device according to the invention with the characterizing features of the main claim has the advantage that an emergency call is triggered automatically.
Besonders vorteilhaft ist, daß der Notruf die Positionsdaten des Kraftfahrzeuges enthält, die durch das Ortungssystem kontinuierlich ermittelt werden. Aufwendige und besonders im Stadtgebiet fehlerbehaftete Peilungen entfallen. It is particularly advantageous that the emergency call contains the position data of the motor vehicle, which are continuously determined by the location system. Elaborate and especially faulty bearings are eliminated.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Notrufeinrichtung möglich. Advantageous further developments and improvements of the emergency call device specified in the main claim are possible through the measures listed in the subclaims.
Vorteilhaft ist, daß die Notrufeinrichtung eine Pufferbatterie aufweist, die bei Ausfall der in einem Kraftfahrzeug vorhandenen Versorgungsspannung die einwandfreie Funktion der Notrufeinrichtung sicherstellt. Dieses ist besonders auch dann vorteilhaft, wenn beispielsweise das Kraftfahrzeug entwendet wird und die eingebaute Alarmanlage einen Notruf auslöst Auch ist vorteilhaft, wenn das einen Notruf auslösende Signale eines Signalgebers über Infrarotsende-/Empfangseinrichtungen übertragen wird, weil dadurch die Installation von weiteren Signalgebern sehr vereinfacht wird. It is advantageous that the emergency call device has a backup battery which ensures the proper functioning of the emergency call device in the event of a failure of the supply voltage present in a motor vehicle. This is particularly advantageous when, for example, the motor vehicle is stolen and the built-in alarm system triggers an emergency call It is also advantageous if the signals from a signal transmitter that trigger an emergency call are transmitted via infrared transmitters / receivers, because this greatly simplifies the installation of further signal transmitters.
Besonders vorteilhaft ist, daß der Notruf auch fahrzeugspezifische Daten, vorzugsweise das Kennzeichen, den Fahrzeugtyp oder die Gefahrenklasse bei Massenguttransportern oder die Rufnummer des Kraftfahrzeuges enthält. So können der Unfallmeldestation bereits wichtige Detailinformationen mitgeteilt werden, aus denen die Notsituation erkennbar wird. In diesem Zusammenhang können auch Daten bezüglich der Fahrzeuginsassen, deren Sitzposition und des Ünfallhergangs wie beispielsweise der Ausbruch eines Feuers übermittelt werden. Bei der Unfallmeldestation sind dann in vorteilhafter Weise bereits die ersten zielführenden Maßnahmen zur Rettung von Verletzten einleitbar. Die Fahrzeuginsassen werden durch Kontakte am Sitz oder am Anschnallgurt in vorteilhafter Weise ermittelt. It is particularly advantageous that the emergency call also contains vehicle-specific data, preferably the number plate, the vehicle type or the hazard class for bulk carriers or the telephone number of the motor vehicle. In this way, the accident reporting station can already be provided with important detailed information from which the emergency situation can be identified. In this context, data relating to the vehicle occupants, their seating position and the incident, such as the outbreak of a fire, can also be transmitted. At the accident reporting station, the first targeted measures for rescuing injured persons can then advantageously be initiated. The vehicle occupants are advantageously determined by contacts on the seat or on the seat belt.
Weiterhin ist vorteilhaft, daß der Notruf mehrfach abgesetzt wird, um Ubertragungsfehler zu vermeiden. It is also advantageous that the emergency call is made several times in order to avoid transmission errors.
Auch ist vorteilhaft, daß zusätzlich eine manuell bedienbare Notruftaste vorsehbar ist, so daß auch ein anderer Verkehrsteilnehmer, der einen Unfall beobachtet, einen Notruf auslösen und Hilfe herbeirufer kann. Um einen Fehlalarm zu vermeiden, ist es vorteilhaft, wenn die Notruftaste eine gewisse Dauer zu betätigen ist. Dadurch wird vermieden, daß durch versehentliches Betätigen der Notruftaste bereits ein Notruf ausgelöst wird und aufwendige Rettungsmaßnahmen der Unfallmeldestelle eingeleitet werden. Ein weiterer vorteilhafter Schutz gegen eine Fehlauslösung des Alarmsignals wird durch eine Schutzklappe über der Notruftaste erreicht. Besonders vorteilhaft ist auch, daß die in einem Notfall anzurufenden Nummern frei eingebbar sind und bereits abgespeichert sind, bevor ein Notruf erfolgt. Dadurch wird die automatische Auslösung eines Notrufs vereinfacht. Die Reihenfolge der zu informierenden Personen und Stellen ist damit festgelegt. It is also advantageous that a manually operated emergency call button can also be provided, so that another road user who is watching an accident can trigger an emergency call and call for help. To avoid a false alarm, it is advantageous if the emergency button has to be pressed for a certain period. This avoids that an emergency call is triggered by inadvertently actuating the emergency call button and complex rescue measures of the accident reporting center are initiated. A further advantageous protection against a false triggering of the alarm signal is achieved by a protective flap above the emergency call button. It is also particularly advantageous that the numbers to be called in an emergency can be freely entered and are already stored before an emergency call is made. This simplifies the automatic triggering of an emergency call. The order of the people and positions to be informed is thus determined.
Besonders vorteilhaft ist auch, daß der Notruf in der Empfangsstation beispielsweise auf einem Monitor im Klartext ausgegeben wird. Dadurch kann auf einfache Weise gleich ein Protokoll über die Ursache des Notrufes mit den notwendigen Einzelheiten erstellt werden, ohne daß Hörfehler oder Verständigungsprobleme auftreten und zu unerwünschten Verzögerungen führen. It is also particularly advantageous that the emergency call in the receiving station is output, for example, on a monitor in plain text. As a result, a log of the cause of the emergency call with the necessary details can be created in a simple manner, without hearing errors or communication problems occurring and leading to undesirable delays.
Ein weiterer Vorteil besteht darin, daß ein Mobiltelefon als Notfunkgerät Verwendung findet. Da für das Mobiltelefon bereits Another advantage is that a mobile phone is used as an emergency radio. As for the cell phone already
Sende- und Empfangsnetze zur Verfügung stehen, ist die Notrufeinrichtung besonders wirtschaftlich herstellbar. Sending and receiving networks are available, the emergency call device is particularly economical to manufacture.
Weiterhin ist vorteilhaft, wenn beim Diebstahl eines Kraftfahrzeuges durch eine Alarmanlage ein stiller Alarm ausgelöst wird. Da im Notruf auch die momentane Fahrzeugposition aufgrund eines eingebauten Ortungs- und Navigationssystems mit übertragen wird, kann an der Empfangsstation der momentane Standpunkt des Kraftfahrzeuges ermittelt werden. Da ein vermeintlicher Dieb diese Alarmauslösung nicht bemerkt, fühlt er sich sicher. Er kann dadurch leichter verfolgt und schließlich ergriffen werden. It is also advantageous if a silent alarm is triggered by an alarm system when a motor vehicle is stolen. Since the current vehicle position is also transmitted in the emergency call due to a built-in location and navigation system, the current position of the motor vehicle can be determined at the receiving station. Since a supposed thief does not notice this alarm, he feels safe. This makes it easier for him to be followed and finally taken.
Eine vorteilhafte Weiterbildung der Erfindung ist auch durch die Verwendung eines Neigungssensors oder das Blockieren der Zündeinrichtung zu sehen, weil durch das Aufladen des Fahrzeuges ein Alarm ausgelöst oder ein Wegfahren verhindert wird. Bei einem Unfall ist zur Beweissicherung besonders vorteilhaft, wenn das Notrufsignal Informationen über die Fahrzeuggeschwindigkeit bzw. die Bremsverzögerung enthält. An advantageous further development of the invention can also be seen through the use of an inclination sensor or the blocking of the ignition device, because an alarm is triggered or a drive away is prevented by charging the vehicle. In the event of an accident, it is particularly advantageous for the preservation of evidence if the emergency call signal contains information about the vehicle speed or the braking deceleration.
Aus der Beschreibung sind weitere vorteilhafte Weiterbildungen und Verbesserungen der erfindungsgemäßen Notrufeinrichtung ersichtlich. Further advantageous developments and improvements of the emergency call device according to the invention can be seen from the description.

Beschreibung des Ausführungsbeispiels Description of the embodiment
In Figur 1 ist das Blockschaltbild der in dem Kraftfahrzeug mitgeführten Notrufeinrichtung 20 dargestellt. Eine Steuereinrichtung 3 weist einen Mikrocomputer auf, der mit dem Speicher 4 verbunden ist. An die Steuereinheit 3 sind über einen Datenbus 15 mehrere Signalgeber angeschlossen, die in dem Ausfuhrungsbeispiel als Ortungs- und Navigationssystem 6, Fahrgastzähler 7, Airbag 8, Alarmanlage 9, Temperatur-/Gassensor 10 und Notruftaste 11 dargestellt sind. Die Steuereinrichtung 3 weist Eingangsklemmen 22 auf, an die der Datenbus 15 angeschlossen wird. Der Ausgang 21 der Steuereinrichtung 3 ist verbunden mit dem Eingang eines Mobiltelefons 1. Das Mobiltelefon 1 entspricht einem käuflich erhältlichen Gerät, an das einerseits eine Hör-/Sprechgarnitur 2 und andererseits eine Sende- und Empfangsantenne 23 angeschlossen ist. Weiterhin ist eine Pufferbatterie 5 vorgesehen, die mit der Steuereinrichtung 3 und dem Mobiltelefon 1 verbunden ist. Die Signalgeber 6, 8 bis 11 sind dem Fachmann bekannt und müssen nicht näher erläutert werden. Der Fahrgast zähler 7 weist einen Zähler auf, der durch Sitzkontakte oder Gurtschlösser triggerbar ist, wobei die Sitzposition in das Zählergebnis eingeht. Zum Beispiel bedeutet das Signal "3", das aus den Binärpotenzen 20 + 21 aaibgeleitet ist, daß ein Fahrer und ein Beifahrer im Fahrzeug sind. FIG. 1 shows the block diagram of the emergency call device 20 carried in the motor vehicle. A control device 3 has a microcomputer which is connected to the memory 4. Several signal transmitters are connected to the control unit 3 via a data bus 15, which are shown in the exemplary embodiment as a location and navigation system 6, passenger counter 7, airbag 8, alarm system 9, temperature / gas sensor 10 and emergency call button 11. The control device 3 has input terminals 22 to which the data bus 15 is connected. The output 21 of the control device 3 is connected to the input of a mobile telephone 1. The mobile telephone 1 corresponds to a commercially available device to which on the one hand a hearing / speaking set 2 and on the other hand a transmitting and receiving antenna 23 is connected. Furthermore, a backup battery 5 is provided, which is connected to the control device 3 and the mobile phone 1. The signal transmitters 6, 8 to 11 are known to the person skilled in the art and need not be explained in more detail. The passenger Counter 7 has a counter that can be triggered by seat contacts or belt buckles, the seat position being included in the counting result. For example, the signal "3" derived from the binary powers 2 0 + 2 1 aaib means that there is a driver and a passenger in the vehicle.
In Figur 2 ist eine Funkleitstelle 40 als Blockschaltbild dargestellt, die mit ihrer Empfangsstation 30 die vom Mobiltelefon 1 abgestrahlten Daten empfangen kann. Der Empfang erfolgt über die Sende- und Empfangsantenne 34. Als Ausgabegeräte weist die Empfangsstation 30 weiterhin einen Monitor 33 zur Darstellung von grafischen oder alphanumerischen Zeichen sowie einen Lautsprecher 31 auf. FIG. 2 shows a radio control center 40 as a block diagram, which can receive the data emitted by the mobile telephone 1 with its receiving station 30. The reception takes place via the transmitting and receiving antenna 34. The receiving station 30 also has a monitor 33 for displaying graphic or alphanumeric characters and a loudspeaker 31 as output devices.
Im folgenden wird die Funktion dieser Notrufeinrichtung beschrieben. The function of this emergency call device is described below.
Die Steuereinrichtung 3 sowie mindestens ein Teil der Signalgeber 6 bis 11 sind ständig in Funktionsbereitschaft. Liegt ein Meldefall vor, dann gibt einer der Signalgeber 8 bis 11 ein Signal an die Steuereinheit 3. Die Signale der Signalgeber sind unterschiedlich codiert, so daß die Steuereinheit 3 erkennen kann, welcher Signalgeber das Meldesignal ausgelöst hat. Die Codierung des Signales erfolgt entweder durch Kennzeichnung mit einer Adresse oder durch unterschiedliche Pulsformen. Aufgrund dieser unterschiedlichen Meldedaten generiert die Steuereinrichtung 3 einen auf die Notsituation abgestimmten Notruf, den sie über das Mobiltelefon 1 sendet. Zur Bildung des Notrufes entnimmt die Steuereinheit 3 aus dem angeschlossenen Speicher 4 vorbereitete Datensätze, damit später die Funkleitstelle 40 den Notruf im Klartext ausgeben kann. Um auf der Funkleitstelle 40 die notwendigen Sofortmaßnahmen optimal einleiten zu können, enthält der Notruf alle wichtigen Daten bezüglich der Notfallsituation. Diese Daten werden in Form eines Notruftelegramms gesendet und enthalten gemäß Figur 3 die Merkmale Notrufursache 41, Kfz-Kennzeichen/Halter 42, Fahrzeugart 43, Typ/Farbe 44, Position des Fahrzeuges 45, Gefahrenklasse 46, Anzahl Fahrgäste 47, Sitzpositionen 48 der Fahrgäste, Geschwindigkeits- und Verzögerungsmessung 49, Geschwindigkeitsüberschreitung 40, Fahren gegen eine vorgeschriebene Fahrtrichtung ("Geisterfahrer") 51 sowie sonstige Hinweise wie Handauslösung des Notrufs 52. Selbstverständlich kann der Notruf auch weitere Informationen enthalten, beispielsweise ob das Fahrzeug noch in Bewegung ist oder ob es steht. Dieses ist dann wichtig, wenn ein Fahrzeug gestohlen wird und die Alarmanlage einen Notruf ausgelöst hat. The control device 3 and at least some of the signal transmitters 6 to 11 are always ready for operation. If there is a report, one of the signal generators 8 to 11 sends a signal to the control unit 3. The signals of the signal generators are coded differently, so that the control unit 3 can recognize which signal generator has triggered the signal. The signal is encoded either by labeling it with an address or by different pulse shapes. On the basis of these different reporting data, the control device 3 generates an emergency call which is coordinated with the emergency situation and which it sends via the mobile telephone 1. To form the emergency call, the control unit 3 takes prepared data records from the connected memory 4 so that the radio control center 40 can later issue the emergency call in plain text. In order to be able to optimally initiate the necessary immediate measures on the radio control center 40, the emergency call contains all important data relating to the emergency situation. These data are sent in the form of an emergency telegram and contain, according to FIG. 3, the features of the cause of the emergency call 41, vehicle registration number / holder 42, vehicle type 43, type / color 44, position of the vehicle 45, hazard class 46, number of passengers 47, seating positions 48 of the passengers, speed and deceleration measurement 49, overspeed 40, driving against a prescribed direction of travel ("ghost driver") 51 as well as other information such as manual triggering of the emergency call 52. Of course, the emergency call can also contain further information, for example whether the vehicle is still moving or whether it is stationary. This is important if a vehicle is stolen and the alarm system has triggered an emergency call.
Auch sind als Signalgeber Funktionskontrollgeber des Fahrzeuges vorgesehen, so daß bei einer Motorpanne oder einer Reifenpanne ein entsprechender Notruf gesendet wird. Weiterhin wird bei einem Unfall die Bremsverzögerung und die Aufschlagsgeschwindigkeit auf ein Hindernis gemeldet, wobei vorher die Fahrtgeschwindigkeit ermittelt und zur Bremsdauer in Beziehung gesetzt wurde. Function control transmitters of the vehicle are also provided as signal transmitters, so that a corresponding emergency call is sent in the event of an engine breakdown or a tire breakdown. In the event of an accident, the braking deceleration and the impact speed on an obstacle are also reported, the driving speed having previously been determined and related to the braking time.
Der Notruf enthält auch Daten über die Fahrzeugbewegung. Insbesondere wird bei Verwendung eines plangestützen Ortungs- und Navigationssystems das Befahren einer gesperrten Straße, das Fahren gegen die vorgeschriebene Fahrtrichtung und die Übertretung von Geschwindigkeitsbegrenzungen übertragen. The emergency call also contains data on vehicle movement. In particular, when using a map-based location and navigation system, driving on a blocked road, driving against the prescribed direction of travel and violating speed limits are transmitted.
Eine Begrenzung auf die in dem Ausführungsbeispiel angegebenen Signalgeber ist nicht gegeben. Sie werden im Bedarfsfall ausgetauscht oder ergänzt. Insbesondere bei einer kabellosen Signalübertragung zwischen dem Signalgeber und der Steuereinrichtung 3, wie sie beispielsweise durch eine Infrarot-Sende- und Empfangseinrichtung gegeben ist, sind die Signalgeber auf einfache Weise ergänzbar und an die Erfordernisse anpaßbar. Wurde eine Alarmanlage 9 eingebaut, dann wird bei einem Einbruch oder bei Diebstahl des Kraftfahrzeuges ein Notruf ausgelöst, der in der Funkleitstelle 40 auf dem Monitor angezeigt wird und bei Bedarf über einen Sprachsynthesizer im Klartext ausgegeben werden kann. In diesem Fall ist es zweckmäßig, neben den Fahrzeugkenndaten wie dem Kennzeichen, dem Fahrzeugtyp und der Fahrzeugfarbe auch die laufende Position zu übertragen. Ist das Ortungs- und Navigationsgerät mit einem Neigungssensor ausgerüstet, dann führt auch das Abschleppen dieses Fahrzeuges oder Aufladen auf ein Transportfahrzeug zu einem Auslösen des Notrufes. There is no limitation to the signal transmitters specified in the exemplary embodiment. If necessary, they will be exchanged or supplemented. In particular in the case of wireless signal transmission between the signal transmitter and the control device 3, as is given, for example, by an infrared transmitter and receiver device, the signal transmitters can be easily supplemented and adapted to the requirements. If an alarm system 9 was installed, an emergency call is triggered in the event of a break-in or theft of the motor vehicle, which is displayed on the monitor in the radio control center 40 and, if necessary, in plain text via a speech synthesizer can be spent. In this case, it is useful to transfer the current position in addition to the vehicle identification data such as the license plate, the vehicle type and the vehicle color. If the location and navigation device is equipped with an inclination sensor, then towing this vehicle or loading it onto a transport vehicle also triggers the emergency call.
Unabhängig von den automatisch arbeitenden Signalgebern kann über eine Handtaste ein Notruf ausgelöst werden. Zum Schutz gegen einen Fehlalarm sind hier besondere Maßnahmen erforderlich. Eine Maßnahme beinhaltet die Abdeckung des NotrufSchalters. Eine andere Maßnahme ist darin zu sehen, daß der Notruf von dem Mobiltelefon 1 erst dann abgestrahlt wird, wenn die Notruftaste mindestens eine gewisse Zeit lang gedrückt wurde. Dadurch ist sichergestellt, daß kein kurzfristiges und versehentliches Berühren der Notruftaste zu einem Alarm führt. Durch die angeschlossene Pufferbatterie 5 ist gewährleistet, daß die Notrufeinrichtung auch ohne die Fahrzeugbatterie funktionsfähig bleibt, wenn in einem Unfallfall die An emergency call can be triggered using a manual button, regardless of the automatic signaling devices. Special measures are required to protect against a false alarm. One measure includes covering the emergency call switch. Another measure can be seen in the fact that the emergency call is only emitted from the mobile telephone 1 when the emergency call button has been pressed for at least a certain time. This ensures that no short-term and accidental touching of the emergency button leads to an alarm. The connected backup battery 5 ensures that the emergency call device remains functional even without the vehicle battery if the in an accident
Fahrzeugbatterie abgetrennt wurde oder funktionsunfähig ist. Vehicle battery has been disconnected or is inoperable.
Der Speicher 4 kann neben den Datensätzen für den Notruf auch unterschiedliche Telefonnummern oder Rufnummern enthalten. Je nachdem, welches Gebersignal angesprochen hat, kann eine unterschiedliche Rufnummer angewählt werden. Bei einem Verkehrsunfall kann beispielsweise auf diese Weise das Unfallkrankenhaus angerufen werden, während bei einem Autodiebstahl vornehmlich der Eigentümer bzw. die Polizei benachrichtigt wird. Bei entsprechender Anbringung der Notrufeinrichtung im Kraftfahrzeug ist ein mutwilliges Zerstören der Notrufeinrichtung sowie ein Abschalten der Notrufeinrichtung vermeidbar. In addition to the data records for the emergency call, the memory 4 can also contain different telephone numbers or numbers. Depending on which encoder signal has responded, a different number can be dialed. In the event of a traffic accident, the accident hospital can be called in this way, for example, while the owner or the police are primarily notified in the event of a car theft. If the emergency call device is appropriately installed in the motor vehicle, a willful destruction of the emergency call device and a switching off of the emergency call device can be avoided.
Unabhängig von der Notrufeinrichtung kann das Mobiltelefon 1 wie ein übliches Funktelefon verwendet werden. Regardless of the emergency call device, the mobile phone 1 can be used like a conventional radio telephone.
