Description
Die Erfindung betrifft Sicherheits- und Rettungssysteme. Insbesondere betrifft die Erfindung eine Notrufeinrichtung für ein Fahrzeug und ein Notrufsystem.The invention relates to safety and rescue systems. In particular, the invention relates to an emergency call device for a vehicle and an emergency call system.
Fahrzeug-Notfunksysteme sind seit langem bekannt. Beispielsweise ist aus
- a) dass die Positionsbestimmungseinrichtung während der (gesamten) Betriebsphase des Fahrzeugs fortlaufend, vorzugsweise in vorgegebenen zeitlichen Abständen automatisch die momentane Position des Fahrzeugs ermittelt und die ermittelten Positionsdaten dem Notrufsender übergibt, und
- b) dass die Positionsdaten im Notrufsender bis zum Empfang neuer Positionsdaten von der Positionsbestimmungseinrichtung gespeichert bleiben.
- a) that the position-determining device continuously during the (entire) operating phase of the vehicle, preferably automatically determines the instantaneous position of the vehicle at predetermined time intervals and transmits the determined position data to the emergency call transmitter, and
- b) that the position data in the emergency call transmitter remain stored until the receipt of new position data from the position-determining device.
Im Falle eines Unfalls überprüft der mit einer Steuereinheit (welche mit einer Positionsbestimmungseinrichtung und einem Notrufsender, z. B. in Form eines entsprechend modifizierten Autotelefons verbunden ist) verbundene Crashsensor (z. B. der Airbagsensor) anhand vorgegebener Unfallkriterien, ob ein Notrufsignal auszusenden ist oder nicht. Werden die Kriterien erfüllt, gibt der Crashsensor ein Freigabesignal über die Steuereinheit an den Notrufsender, der daraufhin über die zweite Antenne per Funk ein Notrufsignal zusammen mit den momentan abgespeicherten Positionsdaten des Fahrzeugs 1 aussendet. Weiterhin ist es möglich, dass bei Erfüllung der Unfallkriterien der Crashsensor eine erneute Bestimmung der Fahrzeugposition durch die Positionsbestimmungseinrichtung veranlasst und dass diese Positionsdaten zusammen mit dem Notrufsignal vom Notfunksender ausgesendet werden. Schließlich ist es möglich, anstelle eines GPS (Global-Positioning-System) einen Travelpiloten zur Ortsbestimmung einzusetzen.In the event of an accident, the crash sensor (eg the airbag sensor) connected to a control unit (which is connected to a position-determining device and an emergency transmitter, eg in the form of a suitably modified car telephone) checks whether an emergency call signal is to be transmitted on the basis of predetermined accident criteria or not. If the criteria are met, the crash sensor outputs an enable signal via the control unit to the emergency transmitter, which then transmits an emergency call signal together with the currently stored position data of the vehicle 1 via the second antenna. Furthermore, it is possible that upon fulfillment of the accident criteria, the crash sensor causes a re-determination of the vehicle position by the position determination device and that these position data are transmitted together with the emergency call signal from the emergency radio transmitter. Finally, it is possible to use a travel pilot instead of a GPS (Global Positioning System) for location.

- 2) Starten des Notfall-Meldeprozesses durch das Auslesen von Positionsinformation und anderen Daten aus einer Speichereinheit.
- 3) Auslesen der in der Speichereinheit gespeicherten Telefonnummer der Zentrale wie etwa der Polizei oder einer Rettungszentrale, die das Notfall-Meldesystem überwacht.
- 4) Anfordern eines Telefonanrufs bei der Notfall-Meldeeinheit unter Verwendung dieser Telefonnummer.
- 5) Erkennen des Übergangs zum Konversationszustand, wenn ein Antwortsignal von dem der Telefonnummer entsprechenden Partner oder ein zum Konversationszustand überleitendes Signal wie etwa ein Freizeichen empfangen wird.
- 6) Senden von Positionsinformation und Verlaufsdaten, die von der Positionsinformations-Erfassungs-/Verarbeitungseinheit erhalten wurden, sowie des Zentralenanrufsignals über die Basisstation der Kommunikationseinrichtung an die Notfall-Meldeeinheit.
- 1) detecting an emergency call request based on an operation signal from an emergency notification button, an airbag development signal output from the airbag device in an impact or an accident, or an automatic emergency notification signal based on a fuel cutoff signal.
- 2) Start the emergency notification process by reading position information and other data from a storage unit.
- 3) reading the stored in the storage unit phone number of the headquarters such as the police or a rescue center that monitors the emergency reporting system.
- 4) Request a telephone call to the emergency reporting unit using this telephone number.
- 5) detecting the transition to the conversation state when receiving a response signal from the partner corresponding to the telephone number or a conversation-state-passing signal such as a dial tone.
- 6) sending position information and history data obtained from the position information acquisition / processing unit and the central call signal via the base station of the communication device to the emergency notification unit.

Weiterhin sind umfangreiche Vorkehrungen gegenüber unbeabsichtigten Auslösevorgängen für einen Notruf zu treffen. Auch die Auslösung mittels abgespeicherter Schlüsselwörter bei einem vom Benutzer mitgeführten Mobiltelefon/Notrufsender versagt, wenn der Verkehrsteilnehmer nach einem Unfall selbst dazu nicht mehr in der Lage ist. Deshalb fehlt in der Praxis ein Fahrzeug-Notfunksystem, welches unabhängig von anderen technischen Gegebenheiten universell einsetzbar ist und welches im Falle eines Unfalls automatisch einen Notruf auslöst.Furthermore, extensive precautions must be taken against unintentional tripping procedures for an emergency call. The triggering by means of stored keywords in a user-carried mobile phone / emergency transmitter fails if the road user after an accident itself is no longer able to do so. Therefore, in practice, a vehicle emergency radio system is missing, which is universally applicable regardless of other technical conditions and which automatically triggers an emergency call in the event of an accident.
Es ist eine Aufgabe der Erfindung, eine verbesserte Automatisierung von Notrufen bereitzustellen.It is an object of the invention to provide an improved automation of emergency calls.
Es sind eine Notrufeinrichtung und ein Notrufsystem den Merkmalen der unabhängigen Ansprüche 1 und 10 angegeben. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.There are an emergency call device and an emergency call system the features of the independent claims 1 and 10 specified. Further developments of the invention will become apparent from the dependent claims.
Die beschriebenen Ausführungsbeispiele betreffen gleichermaßen die Einrichtung und das System.The described embodiments equally relate to the device and the system.
Gemäß einem Ausführungsbeispiel der Erfindung ist eine Notrufeinrichtung für ein Fahrzeug zum Übermitteln eines Notrufs angegeben, wobei die Notrufeinrichtung eine Detektionseinheit zur Erfassung von Messdaten, eine Steuereinheit zur Umsetzung von Daten, die mit den erfassten Messdaten korrespondieren, mittels einer Medienkonvertierung in eine erste Information, und eine Kommunikationseinheit zur Übermittlung eines Notrufs an einen Empfänger aufweist. Der Notruf umfasst die erste Information und eine zweite Information. Die zweite Information korrespondiert hierbei mit einer akustischen Benutzereingabe, wie z. B. eines von einem Fahrzeuginsassen gesprochenen Textes.According to one exemplary embodiment of the invention, an emergency call device for a vehicle for transmitting an emergency call is specified, wherein the emergency call device comprises a detection unit for acquiring measured data, a control unit for converting data corresponding to the acquired measured data by means of a media conversion into a first information, and a communication unit for transmitting an emergency call to a receiver. The emergency call includes the first information and a second information. The second information corresponds with an acoustic user input, such. B. a spoken by a vehicle occupant text.
In anderen Worten können die Daten mittels der Medienkonvertierung in Sprache oder andere Formate verwandelt werden (z.B. mittels Text-to-Speech, TTS) und dann über einen entsprechenden Sprachkanal übertragen werden. Zusätzlich zu den unfallspezifischen, automatisch übertragenen Daten können auch Sprachinformationen des Benutzers übertragen werden.In other words, the data can be converted into speech or other formats (e.g., by text-to-speech, TTS) by means of media conversion, and then transmitted over a corresponding voice channel. In addition to the accident-specific, automatically transmitted data, voice information of the user can also be transmitted.
Es ist also ein Datenkanal für die Übertragung der konvertierten Daten des Teilnehmers und von anderen, zusätzlichen Daten, die vom System automatisch erstellt werden und welche der genauen Identifikation z. B. des Unfallortes oder der Schwere oder Art des Unfalls dienen, vorgesehen. Die unfallspezifischen Daten können ebenfalls in Form von Sprache übertragen werden.So it is a data channel for the transmission of the subscriber's converted data and other, additional data automatically generated by the system and which of the exact identification z. B. the accident location or the severity or nature of the accident, provided. The Accident-specific data can also be transmitted in the form of voice.
Durch eine reine Nutzung von z.B. Sprache als Übertragungsmedium ist keine Standardisierung der Datenschnittstelle notwendig und auch keine Änderung der Infrastruktur. Hierzu werden die Daten in Sprache mittels Text-to-Speech umgesetzt und Daten, die die normale Sprache eines Insassen des Fahrzeugs repräsentieren, werden, falls erforderlich, während der Übertragung gepuffert.By a pure use of e.g. Language as a transmission medium, no standardization of the data interface is necessary and no change in infrastructure. For this purpose, the data is converted into speech by means of text-to-speech, and data representing the normal speech of an occupant of the vehicle is buffered during transmission, if necessary.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist die Kommunikationseinheit zur Übermittlung der ersten Information und der zweiten Information in demselben Übertragungskanal ausgeführt.According to a further exemplary embodiment of the invention, the communication unit is designed to transmit the first information and the second information in the same transmission channel.
Eine Bereitstellung mehrerer Übertragungskanäle ist nicht erforderlich.It is not necessary to provide multiple transmission channels.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung sind die Kommunikationseinheit und/oder die Steuereinheit zur seriellen Übermittlung der ersten Information und der zweiten Information ausgeführt.According to a further exemplary embodiment of the invention, the communication unit and / or the control unit are designed for the serial transmission of the first information and the second information.
Beispielsweise kann die Übermittlung der (gesprochenen) zweiten Information unterbrochen werden, wenn eine erste Information (die mit den erfassten Messdaten korrespondiert) zur Übermittlung bereitsteht oder von einem Empfänger angefordert wird.For example, the transmission of the (spoken) second information may be interrupted if a first information (which corresponds to the acquired measurement data) is ready for transmission or is requested by a receiver.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Steuereinheit zur Umsetzung der Daten in die erste Information einen Sprachsynthesizer auf, der zur Umsetzung von Daten mittels Sprachsynthese ausgeführt ist.According to a further exemplary embodiment of the invention, the control unit for converting the data into the first information comprises a speech synthesizer which is designed to convert data by means of speech synthesis.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung sind die Kommunikationseinheit und/oder die Steuereinheit zur Übermittlung der ersten Information ausgeführt, wenn über einen vorgebbaren Zeitraum keine Stimme aus dem Fahrzeug zu vernehmen ist.According to a further exemplary embodiment of the invention, the communication unit and / or the control unit are designed to transmit the first information if no voice can be heard from the vehicle for a predeterminable period of time.
In anderen Worten werden die unfallspezifischen, gemessenen Informationen spätestens dann, ggf. zum wiederholten Male, gesendet, wenn die Fahrzeuginsassen keine akustischen Informationen von sich geben. Auf diese Weise können zeitliche Lücken in dem akustischen Informationsstrom der Insassen dazu genutzt werden, die Messdaten zu übermitteln.In other words, the accident-specific, measured information is sent at the latest then, if necessary repeatedly, when the vehicle occupants do not give any acoustic information. In this way, temporal Gaps in the acoustic information stream of the occupants are used to transmit the measurement data.
Wenn der Empfänger eine Anfrage an die Kommunikationseinheit sendet, dass er die ersten Informationen benötigt, werden die ersten Informationen gesendet. Wenn der Empfänger hingegen Interesse an den zweiten Informationen hat, werden nur die zweiten Informationen gesendet. Der Empfänger kann also bestimmen, welche Art von Informationen er empfangen möchte. Gemäß einem weiteren Ausführungsbeispiel der Erfindung weist die Notrufeinrichtung weiterhin eine Eingabeeinheit mit einem Pufferspeicher zur Aufnahme und Zwischenspeicherung der akustischen Eingabe eines Insassen des Fahrzeugs auf.When the receiver sends a request to the communication unit that it needs the first information, the first information is sent. On the other hand, if the recipient is interested in the second information, only the second information is sent. The receiver can thus determine what kind of information he wants to receive. According to a further exemplary embodiment of the invention, the emergency call device furthermore has an input unit with a buffer memory for receiving and temporarily storing the acoustic input of an occupant of the vehicle.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung handelt es sich bei dem Empfänger um ein mobiles Endgerät. Bei dem Empfänger kann es sich auch um eine Rettungsleitzentrale mit einem zentralen Server handeln, über die eine Rettungsaktion zentral und weitgehend automatisch gesteuert wird.According to a further embodiment of the invention, the receiver is a mobile terminal. The recipient can also be a rescue control center with a central server via which a rescue operation is centrally and largely automatically controlled.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung handelt es sich bei dem Empfänger um ein fest eingebautes NAD (Network Access Device).According to a further embodiment of the invention, the receiver is a permanently installed NAD (Network Access Device).
Gemäß einem weiteren Ausführungsbeispiel der Erfindung handelt es sich bei der Kommunikationsverbindung zur Übermittlung der Sprachinformation um eine schmalbandige Kommunikationsverbindung.According to a further exemplary embodiment of the invention, the communication connection for transmitting the speech information is a narrowband communication connection.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist die Steuereinheit zur Auswertung der Messwerte ausgeführt, wobei die Steuereinheit auf Basis der Auswertung entscheiden kann, ob sich ein Unfall ereignet hat, und wobei die Sprachinformationen nur dann übermittelt werden, wenn die Auswertung auf einen erfolgten Unfall hindeutet.According to a further exemplary embodiment of the invention, the control unit is designed for evaluating the measured values, wherein the control unit can decide on the basis of the evaluation whether an accident has occurred, and wherein the voice information is transmitted only if the evaluation indicates a crash.
Beispielsweise kann durch eine Auswertung und Analyse der Messwerte ein automatischer Notruf getriggert werden. Eine Benutzereingabe ist hierfür nicht erforderlich.For example, an automatic emergency call can be triggered by evaluating and analyzing the measured values. User input is not required.
Somit können auf einfache Art und Weise ein Notruf ausgelöst und die relevanten Daten übermittelt werden, auch wenn der Benutzer nach einem Unfall selbst dazu nicht mehr in der Lage ist, zu übermitteln.Thus, an emergency call can be triggered in a simple manner and the relevant data is transmitted, even if the user after an accident itself is no longer able to transmit.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist ein Notrufsystem angegeben, welches eine oben beschriebene Notrufeinrichtung und einen Empfänger zum Empfang der ersten Information und der zweiten Information aufweist.According to a further embodiment of the invention, an emergency call system is provided, which has an emergency call device described above and a receiver for receiving the first information and the second information.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist der Empfänger zur automatischen Vornahme eines Rückrufs beim Empfang eines Notrufs ausgeführt, wenn innerhalb einer vorgegebenen Zeitspanne keine weitere Meldung des Insassen des Fahrzeugs empfangen wird, wobei der Empfänger dann entsprechende Rettungsmaßnahmen einleitet. Die Notrufeinheit ist hierbei so ausgelegt, dass sie zurückgerufen werden kann und diesen Rückruf entgegennehmen kann.According to a further embodiment of the invention, the receiver is executed to automatically make a callback upon receipt of an emergency call, if within a predetermined period no further message of the occupant of the vehicle is received, the receiver then initiates appropriate rescue measures. The emergency call unit is designed so that it can be called back and can accept this callback.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist die Verwendung einer oben beschriebenen Notrufeinrichtung in einem Fahrzeug angegeben.According to a further embodiment of the invention, the use of an emergency call device described above in a vehicle is specified.
Gemäß einem weiteren Ausführungsbeispiel der Erfindung ist ein Verfahren zum Übermitteln eines Notrufs von einem Fahrzeug angegeben, bei dem Messdaten erfasst werden, Daten, die mit den erfassten Messdaten korrespondieren, mittels einer Medienkonvertierung in eine erste Information umgesetzt werden und ein Notruf an einen Empfänger übermittelt wird, der die erste Information und eine zweite Information aufweist, wobei die zweite Information mit einer akustischen Benutzereingabe korrespondiert.In accordance with another embodiment of the invention, a method is for transmitting an emergency call from a vehicle in which measurement data is acquired, data corresponding to the acquired measurement data is converted by means of a media conversion into a first information, and an emergency call is transmitted to a receiver having the first information and a second information, the second information having an acoustic user input corresponds.
Eine grundsätzliche Überlegung der Erfindung ist darin zu sehen, dass Daten mittels Text-to-Speech in Sprache umgewandelt werden und dann zusammen mit der Sprache eines Fahrzeuginsassen versendet werden. Die Versendung der umgewandelten, konvertierten Daten und der Sprache des Insassen erfolgt seriell im selben Datenkanal.A basic consideration of the invention is that data is converted to speech using text-to-speech and then sent along with the language of a vehicle occupant. The transmission of the converted, converted data and the language of the occupant takes place serially in the same data channel.
Im Folgenden werden mit Verweis auf die Figuren bevorzugte Ausführungsbeispiele der Erfindung beschrieben.In the following, preferred embodiments of the invention will be described with reference to the figures.
Die Darstellungen in den Figuren sind schematisch und nicht maßstäblich.The illustrations in the figures are schematic and not to scale.
In der folgenden Figurenbeschreibung werden für die gleichen oder ähnlichen Elemente die gleichen Bezugsziffern verwendet.In the following description of the figures, the same reference numerals are used for the same or similar elements.
Die Notrufeinrichtung 100 ist beispielsweise in einem Fahrzeug eingebaut. Bei der Notrufeinrichtung 100 kann es sich aber auch um ein mobiles System handeln, welches vom Benutzer mitgenommen werden kann, also nicht fest im Fahrzeug installiert ist.The
Die Notrufeinrichtung 100 weist eine Eingabeeinheit 112 auf, die mit der Steuereinheit 102 verbunden ist. Bei der Eingabeeinheit 112 handelt es sich beispielsweise um ein Steuergerät, über das ein Benutzer Spracheingaben tätigen kann.The
Weiterhin können über die Eingabeeinheit 112 verschiedene Einstellungen der Notrufeinrichtung 100 vorgenommen werden und beispielsweise ein Zielort und ggf. auch ein Standort für eine Navigationseinheit gewählt werden. Die Eingabe des Zielortes ist dabei beispielsweise durch Eingabe des vollständigen Namens des Zielortes oder auch durch Auswahl aus einer Liste, die auf einer optischen Ausgabeeinheit, wie beispielsweise einem Monitor 110, dargestellt wird, möglich. Auf dem Monitor 110 werden auch die Zielführungsinformationen ausgegeben. Darüber hinaus können die Zielführungsinformationen auch über eine akustische Ausgabeeinheit 111 ausgegeben werden. Die Ausgabe über die akustische Ausgabeeinheit 111 hat den Vorteil, dass der Fahrer weniger vom aktuellen Verkehrsgeschehen abgelenkt wird. In einem Speicherelement oder Speicherpuffer 113, das mit der zentralen Steuereinheit 102 verbunden ist, sind Landkartendaten (Navigationskartendaten) bzw. digitale Kartendaten in Form von Datensätzen abgelegt. Beispielsweise sind in dem Speicherelement 113 auch zusätzliche Informationen über Verkehrsbeschränkungen und dergleichen abgelegt und den Datensätzen zugeordnet. Ein Navigationsgerät ist hier nicht notwendig. Die Navigationsfähigkeit ist kein wesentlicher Bestandteil des Systems.Furthermore, various settings of the
Zur Bestimmung der aktuellen Fahrzeugposition weist die Notrufeinrichtung 100 eine Navigationseinheit mit einem GPS-Empfänger 106 auf, der zum Empfang von Navigationssignalen von GPS-Satelliten ausgelegt ist. Natürlich kann die Navigationseinheit mit dem GPS-Empfänger 106 auch für andere Satellitennavigationssysteme ausgeführt sein.To determine the current vehicle position, the
Es sei darauf hingewiesen, dass im kontext der vorliegenden Erfindung GPS stellvertretend für sämtliche globale Navigationssatellitensysteme (GMSs) steht, wie z. B. GPS, Galileo, GLONASS (Russland), Compass (China), IRNSS (Indien), ....It should be noted that in the context of the present invention, GPS is representative of all global navigation satellite systems (GMSs) such. GPS, Galileo, GLONASS (Russia), Compass (China), IRNSS (India), ....
Weiterhin sei darauf hingewiesen, dass es sich bei dem Fahrzeug beispielsweise um ein Kraftfahrzeug, wie Auto, Bus oder Lastkraftwagen, oder aber auch um Schienenfahrzeug, ein Schiff, ein Luftfahrzeug, wie Helikopter oder Flugzeug, oder beispielsweise um ein Fahrrad handelt.It should also be noted that the vehicle is, for example, a motor vehicle, such as a car, bus or truck, or else a rail vehicle, a ship, an aircraft, such as a helicopter or airplane, or, for example, a bicycle.
Da die GPS-Signale im innerstädtischen Bereich nicht immer empfangbar sind, kann die Notrufeinrichtung 100 zur Durchführung einer Koppelnavigation zudem einen Richtungssensor 107, einen Wegstreckensensor 108 sowie einen Lenkradwinkelsensor 109 aufweisen. Ggf. sind auch Federwegsensoren 118 sowie ein ESP-System 104 und ein optischer Detektor 105, wie beispielsweise eine Kamera, oder ein Strahlsensor, wie beispielsweise ein Radar, vorgesehen. Diese Detektoren werden als Detektionseinheit 119 bezeichnet.Since the GPS signals are not always receivable in the inner city area, the
Ferner kann ein Fahrerassistenzsystem 117 vorgesehen werden.Furthermore, a
Die Kommunikationseinheit weist eine Elektronik 115 und eine Sende-/Empfangsantenne 116 zur Kommunikation mit einer Zentrale oder anderen Sendern/Empfängern auf. Um eine Datensicherheit bereitzustellen und einen Missbrauch zu verhindern, kann eine Verschlüsselungseinheit 114 vorgesehen werden, welche zwischen die Steuereinheit 102 und die Kommunikationseinheit 115, 116 geschaltet ist und dem Verschlüsseln der zu sendenden Daten sowie dem Entschlüsseln der empfangenen Daten dient.The communication unit includes
Der Empfänger 200 umfasst eine Empfangselektronik 203 mit einer Antenne 204 zum Empfang der von der Notrufeinrichtung 100 gesendeten Informationen. Die Informationen werden über den Datenkanal 202 gesendet.The
Bei einem automatisierten Notruf (eCall) werden sowohl Daten als auch Sprache übertragen. Die Daten bestehen z. B. aus dem Zeitpunkt des Unfalls, der Position des Unfallfahrzeugs und der Richtung bzw. der Fahrspur, auf der sich der Unfall ereignet hat. Weiterhin können Daten übermittelt werden, welche die Schwere des Unfalls, etc. angeben. Diese Daten werden von der Detektionseinheit 119 (siehe
Eine Aufmodulierung der (Mess-) Daten auf die Sprache und eine anschließende Trennung der Daten und der Sprache an der Empfangsstelle sind nicht erforderlich. Auch ist keine Versendung der Daten per SMS erforderlich.A modulation of the (measurement) data to the language and a subsequent separation of the data and the language at the receiving point are not required. Also, no data transmission via SMS is required.
Sender und Empfänger müssen demnach nicht die gleiche Technik der Decodierung beherrschen.Therefore, the transmitter and receiver do not have to master the same technique of decoding.
Erfindungsgemäß werden sämtliche Informationen nur über eine Sprachverbindung übertragen, ohne die Notwendigkeit einer Decodierung. Hierzu werden die zu übertragenden Daten per Synthesizer in Sprache verwandelt (Text-to-Speech) und somit übertragen. Während der Datenübertragung wird die Sprache aus dem Fahrzeug in einem Puffer zwischengespeichert (ähnlich dem zeitversetzten Fernsehen, auch Timeshift genannt, bei Videorecordern), um keine Informationen zu verlieren.According to the invention, all information is transmitted only over a voice connection without the need for decoding. For this purpose, the data to be transmitted by synthesizer into speech (text-to-speech) and thus transferred. During data transmission, the speech from the vehicle is buffered in a buffer (similar to time-shifted television, also called Timeshift, in video recorders) in order not to lose any information.
Für die Übertragung gibt es mehrere Möglichkeiten, die alternativ genutzt werden können. Bei der ersten Alternative werden gleich nach Aufbau der Verbindung die Daten als Sprache übertragen und anschließend die gepufferte Sprache.There are several possibilities for the transmission, which can be used alternatively. In the first alternative, immediately after establishing the connection, the data is transmitted as speech and then the buffered language.
Bei der zweiten Alternative werden die Daten übertragen, falls über einen vorgegebenen Zeitraum keine Stimme aus dem Fahrzeug zu vernehmen ist. Auf diese Weise können Zeitintervalle für die Datenübertragung genutzt werden, während denen die Insassen nicht sprechen. Beispielsweise können immer dann, wenn die Insassen gerade nicht sprechen, die Daten übermittelt werden, so dass eine gewisse Redundanz bei der Datenübermittlung gegeben ist.In the second alternative, the data is transmitted if no voice can be heard from the vehicle for a given period of time. In this way, time intervals can be used for the data transmission during which the inmates do not speak. For example, whenever the occupants are not speaking, the data may be transmitted so that there is some redundancy in data transmission.
Nach Abschluss des Gesprächs werden die Daten wiederholt übermittelt.After completion of the call, the data is transmitted repeatedly.
Zusätzlich ist noch die Möglichkeit vorgesehen, dass der Empfänger selbst auswählen kann, ob Sprache oder Daten übertragen werden, indem er mit den Tasten seines Telefons den Anruf und die Übertragung fernsteuert. Auf diese Weise kann ein eCall ferngesteuert werden, ähnlich der Funktionalität eines Anrufbeantworters.In addition, there is also the possibility that the receiver himself can select whether voice or data are transmitted by remotely controlling the call and the transmission with the keys of his telephone. In this way, an eCall can be remotely controlled, similar to the functionality of an answering machine.
Diese Lösung kann sowohl über ein fest eingebautes NAD (Network Access Device) erfolgen, als auch über ein mobiles Endgerät, das per Bluetooth oder einer vergleichbaren Technologie mit dem Fahrzeug verbunden ist.This solution can be implemented either via a fixed NAD (Network Access Device) or via a mobile device that is connected to the vehicle via Bluetooth or similar technology.
Durch die Medienkonvertierung, also z.B. die reine Nutzung der Sprache als Übertragungsmedium, sind keine Standardisierung der Datenschnittstelle und auch keine Änderung der Infrastruktur notwendig.By the media conversion, e.g. the pure use of the language as transmission medium, no standardization of the data interface and no change of the infrastructure are necessary.
Wenn ein Unfall von der Notrufeinrichtung über die Auswertung der Messdaten erkannt wird, erfolgt ein Verbindungsaufbau zwischen der Notrufeinrichtung 100 und der Zentrale 200, beispielsweise indem ein entsprechendes Datenpaket 301 an die Zentrale gesendet wird.If an accident is detected by the emergency call device via the evaluation of the measurement data, a connection is established between the
Daraufhin erfolgt in einem ersten Ausführungsbeispiel die Übermittlung der in Sprache umgewandelten textuellen Daten (also des Ergebnisses der Analyse der Messdaten) als Datenpaket 302. Nach dieser Übermittlung erfolgt die Übermittlung der Sprachinformation der Fahrzeuginsassen als Datenpaket 303. Um dem System genügend Zeit zur Übermittlung der Analyseergebnisse 302 zu geben, können die Sprachdaten in der Notrufeinrichtung zwischengepuffert werden.Then, in a first exemplary embodiment, the transmission of the textual data converted into speech (ie the result of the analysis of the measured data) takes place as
In einem anderen Ausführungsbeispiel werden zuerst Sprachdaten der Insassen als Datenpaket 304 übermittelt. Während einer Sprechpause werden die Analyseergebnisse als Datenpaket 305 übermittelt. Nach deren Übermittlung werden weitere Sprachdaten der Insassen als Datenblock 306 übermittelt, welche ggf. teilweise zwischengespeichert wurden, bis die Übermittlung der Analyseergebnisse 305 beendet ist.In another embodiment, voice data of the occupants are first transmitted as
Die Länge einer erforderlichen Sprechpause, nach der mit der Übermittlung der textuellen Daten (in Form von Sprache) begonnen wird, ist vom Benutzer oder von der Zentrale 200 einstellbar.The length of a required speech pause, after which the transmission of the textual data (in the form of speech) is started, is adjustable by the user or by the
Die für die Auslöseursache des Notrufs repräsentativen Informationen werden durch den Sender mittels einer schmalbandigen Kommunikationsverbindung übermittelt, wobei die zu übertragenden Informationen mittels einer Medienkonvertierung in für einen Empfänger hörbare zeitlich begrenzte Sprachinformationen transformiert werden. Während dieser Übertragung werden weitere Sprachinformationen von den in dem Fahrzeug befindlichen Insassen über die fahrzeuginterne Detektionseinheit aufgenommen und gespeichert. Diese weiteren Sprachinformationen können dann in Schritt 404 mittels der bestehenden schmalbandigen Kommunikationsverbindung im Anschluss an die Übertragung der ersten Sprachinformation übertragen werden.The representative of the triggering cause of the emergency call information is transmitted by the transmitter by means of a narrow-band communication link, wherein the information to be transmitted is transformed by means of a media conversion in audible for a receiver temporally limited speech information. During this transmission, further voice information is provided by the occupants located in the vehicle are recorded and stored via the in-vehicle detection unit. This further speech information may then be transmitted in
