Es existieren jedoch noch weitere Standards, die teilweise ebenfalls im Einsatz sind. Die Kommunikation gemäß IEEE 802.11p findet in Europa z. B. in einem Freguenzbereich von 5,875 bis 5,905 GHz statt, wobei ein Kontrollkanal (Control Channel CCH) und mindestens zwei Servicekanäle (Service Channel SCH) realisiert sind. Der Kontrollkanal wird für die Broadcast-Kommunikation genutzt, bei der eine Information an mehrere oder alle Teilnehmer in dem Kommunikationsnetz übertragen werden soll. Dieser Kanal ist für kurze, sicherheitskritische Informationen mit nur geringen Latenzen und für das Kommunikationsmanagement reserviert. Die Servicekanäle dienen der Übermittlung zusätzlicher, nicht sicherheitskritischer Daten, beispielsweise für anwendungsspezifische Informationen, Straßengeometrie , etc .. Vehicle-to-environment communication (C2X or V2X communication) is referred to as wireless communication, which may take the form of vehicle-to-infrastructure communication (C2I) or vehicle-to-vehicle communication (C2C). In this communication, different information is transmitted according to their content as signals on different radio channels. In particular, wireless communication in the specification IEEE 802.11p according to a standard for the communication of intelligent transport systems (ITS) is used in Europe and the USA. However, there are other standards, some of which are also in use. The communication according to IEEE 802.11p takes place in Europe z. B. in a Freguenzbereich from 5.875 to 5.905 GHz instead, with a control channel (control channel CCH) and at least two service channels (service channel SCH) are realized. The control channel is used for the broadcast communication, in which information is to be transmitted to several or all subscribers in the communication network. This channel is reserved for short, low-latency, safety-critical information and communication management. The service channels are used to transmit additional, non-safety-critical data, for example for application-specific information, road geometry, etc.
Die C2X-Kommunikation beruht unter anderem auch darauf, dass Informationen von vielen Teilnehmern in einem Netzwerk, ins- besondere vielen Fahrzeugen, erzeugt und weitergegeben werden. Viele mittels C2X-Kommunikation realisierte Anwendungen nutzen dieses Netzwerk bzw. beruhen auf der Erzeugung und Weitergabe von möglichst vielen Informationen die Sicherheit der Fortbewegung betreffend, z. B. hinsichtlich Staus oder sonstiger Hindernisse oder hinsichtlich der Zustände der Fahrzeuge selbst. Among other things, C2X communication is based on the fact that information from many subscribers in a network, especially special many vehicles, generated and passed on. Many applications realized by means of C2X communication use this network or are based on the generation and transmission of as much information as possible concerning the safety of the movement, eg. As regards congestion or other obstacles or with respect to the states of the vehicles themselves.
Eine Kommunikationseinrichtung für ein Fahrzeug, mit welcher eine solche Kommunikation durchgeführt werden kann, ist bereits aus der Druckschrift WO 2009/074655 AI bekannt. Beispiele für die Nutzung der C2X-Kommunikation sind der Kreuzungsassistent, Fahrtberechtigungsanwendungen, das Auffinden eines abgestellten Fahrzeugs, Fußgängererkennung, Unfallassistent, Abstandsassistent oder dergleichen. A communication device for a vehicle, with which such a communication can be carried out, is already known from the publication WO 2009/074655 AI. Examples of the use of the C2X communication are the intersection assistant, travel authorization applications, finding a parked vehicle, pedestrian detection, accident assistant, distance assistant or the like.
Bisher wird angenommen, dass Fahrzeuge mit einer solchen Korn munikationseinrichtung nur ab Werk ausgerüstet werden können Wenn eine solche Kommunikationseinrichtung eingesetzt wird, vor allem, wenn sie nach IEEE 802.11p ausgeführt ist, könnte es zu Beginn der Einführung derartiger Kommunikationseinrich tungen bzw. eines Kommunikationssystems, das derartige Kommu nikationseinrichtungen nutzt, Probleme hinsichtlich der Akzeptanz geben, da die Ausrüstungsrate der Fahrzeuge anfangs gering sein wird. Im Einführungszeitraum eines C2X-Kommunika tionssystems ist es sehr wahrscheinlich, dass ein Besitzer eines Fahrzeugs mit einer aufwändigen C2X-Kommunikationsein- richtung durch diese nur geringe Vorteile hat, weil die Anzahl der mit einer solchen Kommunikationseinrichtung ausgerüsteten Fahrzeuge noch zu gering ist. Dieses Problem könnte die Einführung des an sich sehr nützlichen Systems behindern oder zumindest verzögern. Up to now, it is assumed that vehicles with such a communication device can only be factory-equipped. If such a communication device is used, especially if it is designed in accordance with IEEE 802.11p, it could be at the beginning of the introduction of such communication devices or a communication system. the use of such Kommu nikationsseinrichtungen give problems of acceptance, since the equipment rate of vehicles will initially be low. In the introduction period of a C2X communication system, it is very likely that an owner of a vehicle with a complex C2X communication device will have only slight advantages as a result of the fact that the number of vehicles equipped with such a communication device is still too small. This problem could hinder or at least delay the introduction of the very useful system.
Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Kommunikationseinrichtung zu schaffen, mit welcher die oben aufgezeigten Startprobleme bei der Einführung eines C2X Systems verringert werden können. Die obige Aufgabe wird durch eine Kommunikationseinrichtung mit den Merkmalen des Anspruchs 1 gelöst. Insbesondere ist die Kommunikationseinrichtung erfindungsgemäß zur Integration in einer Leuchteinheit ausgebildet. The object of the present invention is therefore to provide a communication device with which the above-mentioned starting problems in the introduction of a C2X system can be reduced. The above object is achieved by a communication device having the features of claim 1. In particular, the communication device according to the invention is designed for integration in a lighting unit.
Die Kommunikationseinrichtung verfügt dabei über elektronische Elemente (Elektronik), vorzugsweise eine Datenverarbeitungseinheit und/oder eine Speichereinheit, und/oder über eine Sendeeinheit zum drahtlosen Versenden von fahrzeugrelevanten Informationen, z. B. mindestens eine Sendeantenne (Strahler), und/oder über eine Empfangseinheit zum drahtlosen Empfangen von fahrzeugrelevanten Informationen, z. B. mindestens eine Empfangsantenne. Die Datenverarbeitungseinheit weist vorzugsweise Mittel zum Generieren von fahrzeugrelevanten Informationen auf. Die genannten Einheiten der Kommunikationseinrichtung sind vorzugsweise miteinander verbunden. The communication device has electronic elements (electronics), preferably a data processing unit and / or a memory unit, and / or a transmitting unit for wireless transmission of vehicle-relevant information, eg. B. at least one transmitting antenna (radiator), and / or a receiving unit for wirelessly receiving vehicle-related information, eg. B. at least one receiving antenna. The data processing unit preferably has means for generating vehicle-relevant information. The said units of the communication device are preferably connected to each other.
Die obige Aufgabe wird ferner durch eine Leuchteinheit für ein Fahrzeug gelöst, welche mindestens ein Leuchtmittel und eine Kommunikationseinrichtung zum drahtlosen Übertragen von fahrzeugrelevanten Daten an ein anderes Fahrzeug oder an eine Infrastruktur aufweist. Eine solche Leuchteinheit kann eine Leuchteinheit für einen einzelnen Leuchtentyp, beispielsweise eine Nebelschlussleuchte oder dritte Bremsleuchte, oder auch eine kombinierte Leuchteinheit für mehrere Leuchtentypen, beispielsweise Front- oder Rückscheinwerfer, Blinker, Bremsleuchte und ggf. Nebelschlussleuchte, darstellen. Ferner kann die Kommunikationseinrichtung auch in eine Sonderform einer Leuchteinheit, beispielsweise in eine Leuchteinheit mit einer Rundumkennleuchte und/oder einem Frontblitzer, z. B. für Einsatzfahrzeuge, integriert sein. The above object is further achieved by a lighting unit for a vehicle, which has at least one lighting means and a communication device for the wireless transmission of vehicle-relevant data to another vehicle or to an infrastructure. Such a light unit may be a light unit for a single type of light, such as a rear fog light or third brake light, or a combined light unit for several types of lights, such as front or rear lights, turn signals, brake light and possibly rear fog light represent. Furthermore, the communication device can also be in a special form of a lighting unit, for example in a lighting unit with a rotating beacon and / or a front flashlight, z. B. for emergency vehicles, integrated.
Die erfindungsgemäße Lösung hat den Vorteil, dass die Kommunikationseinrichtung nicht nur in Neuwagen ab Werk eingebaut, sondern auch als Nachrüstlösung angeboten werden kann. Die Nachrüstung einer Leuchteinheit ist problemlos möglich, da heutzutage typischerweise nicht mehr einzelne Leuchtmittel ausgetauscht werden, sondern zunehmend die gesamte Leuchteinheit mit einem einzigen Leuchtentyp oder einer Leuchtentyp- kombination ersetzt wird. Als Nachrüstlösung ist die Leuchteinheit zum Nachrüsten an einem Fahrzeug ausgebildet, das heißt, sie weist z. B. die notwendigen Befestigungsmittel auf, um sie an einer dafür vorgesehenen Position des Fahrzeugs vorzugsweise lösbar zu befestigen. Auch sind die Anschlüsse an das Bordnetz bzw. ein Signaleingang oder -ausgang an Positionen an der Leuchteinheit vorgesehen, die eine einfache Verbindung mit entsprechenden Anschlüssen am Fahrzeug ermöglichen. Als Nachrüstlösung wird auch ein Ersatzmodul für das Originalmodul verstanden, was im Falle eines Defekts des Originalmoduls dieses ersetzt. The solution according to the invention has the advantage that the communication device not only installed in new cars ex works, but can also be offered as a retrofit solution. The retrofitting of a light unit is easily possible, since nowadays typically no longer individual bulbs but increasingly the entire lighting unit is replaced with a single type of luminaire or luminaire type combination. As a retrofit solution, the light unit is designed for retrofitting to a vehicle, that is, it has z. For example, the necessary fastening means to attach them to a designated position of the vehicle preferably releasably. Also, the connections to the electrical system or a signal input or output are provided at positions on the lighting unit, which allow easy connection with corresponding connections on the vehicle. A retrofit solution is also a replacement module for the original module, which replaces it in case of a defect of the original module.
Ferner beinhaltet die erfindungsgemäße Lösung vorzugsweise nur einen begrenzten Funktionsumfang verglichen mit einer C2X-Kommunikationseinrichtung, welche ab Werk eingebaut wird. Der Funktionsumfang der erfindungsgemäßen Kommunikationseinrichtung des betroffenen Fahrzeugs soll insbesondere derart gestaltet sein, dass Fahrer anderer Fahrzeuge besser informiert sind und dadurch indirekt die Sicherheit für den Fahrer des betroffenen Fahrzeugs erhöht wird. Alternativ kann auch der zu der Erstausrüster-Lösung identische Funktionsumfang vorgesehen werden. Furthermore, the solution according to the invention preferably includes only a limited range of functions compared to a C2X communication device which is installed ex works. The functional scope of the communication device according to the invention of the affected vehicle should in particular be designed such that drivers of other vehicles are better informed and thus indirectly the safety for the driver of the affected vehicle is increased. Alternatively, it is also possible to provide the range of functions identical to that of the original equipment manufacturer.
Die Kommunikationseinrichtung wird erfindungsgemäß in eine solche Austausch-Leuchteinheit integriert und kann daher ohne zusätzliche Kosten hinsichtlich des Verbauens in das Fahrzeug in dem jeweiligen Fahrzeug nachgerüstet werden. Eine solche Leuchteinheit stellt auch die erforderliche elektrische Energie für das Betreiben der Kommunikationseinrichtung zur Verfügung, da diese nach dem Einbau in das Fahrzeug mit dem Bordnetz zum Betreiben der Leuchtmittel verbunden sein muss. Ferner kann die Leuchteinheit auch mit einem Signaleingang und/oder einem Signalausgang, welche beispielsweise mit dem Steuergerät des Fahrzeugs verbindbar sind, ausgerüstet sein, um beispielsweise Steuersignale für die Beleuchtung zu erhal- ten oder zu versenden. Über eine Signalleitung im Fahrzeug bzw. in der Leuchteinheit, welche mit den Signalein- und - ausgängen verbunden ist, können die drahtgebunden Signale innerhalb des Fahrzeugs versendet oder empfangen werden. Der Signaleingang und/oder der Signalausgang der Leuchteinheit können mit dem Signaleingang bzw. dem Signalausgang der Kommunikationseinrichtung verbunden sein, so dass die für die Leuchteinheit bestimmten Signale durch die Kommunikationseinrichtung ebenfalls genutzt werden können bzw. von der Kommu- nikationseinrichtung über die Signalleitung Informationen an das Steuergerät des Fahrzeugs weitergegeben werden können. The communication device according to the invention is integrated into such an exchange lighting unit and can therefore be retrofitted without additional costs in terms of the installation in the vehicle in the respective vehicle. Such a lighting unit also provides the required electrical energy for operating the communication device, since it must be connected after installation in the vehicle with the electrical system for operating the bulbs. Furthermore, the lighting unit can also be equipped with a signal input and / or a signal output, which can be connected, for example, to the control unit of the vehicle, in order, for example, to obtain control signals for the lighting. or to send. Via a signal line in the vehicle or in the lighting unit, which is connected to the signal inputs and outputs, the wired signals can be sent or received within the vehicle. The signal input and / or the signal output of the lighting unit can be connected to the signal input or the signal output of the communication device, so that the signals intended for the lighting unit can also be used by the communication device or information from the communication device via the signal line Control unit of the vehicle can be passed.
Ist die Leuchteinheit mit einer separaten elektronischen Steuereinheit bzw. Regeleinheit versehen, so kann die Kommu- nikationseinrichtung idealerweise mit dieser kombiniert werden . If the lighting unit is provided with a separate electronic control unit or control unit, then the communication device can ideally be combined with it.
Zu der vorliegenden Erfindung umfasst die C2X-Kommunikation die Kommunikation beispielsweise mittels WLAN (IEEE To the present invention, the C2X communication comprises the communication, for example by means of WLAN (IEEE
802. lla/b/g/n/p) , mittels zellulärem Funk (GSM, GPRS, EDGE,802. lla / b / g / n / p), by means of cellular radio (GSM, GPRS, EDGE,
UMTS, LTE), mittels WiMax, mittels Bluetooth und dergleichen. Ferner kann die Kommunikation im Rahmen eines Remote-Keyless- Entry-System eingeschlossen sein. Die in der Kommunikationseinheit in einem bevorzugten Ausführungsbeispiel vorgesehene Sendeeinheit und/oder Empfangseinheit sind vorzugsweise für die Versendung bzw. das Empfangen derartiger Funksignale, z. B. als Antennen, ausgebildet. UMTS, LTE), via WiMax, via Bluetooth and the like. Furthermore, the communication may be included as part of a remote keyless entry system. The transmission unit and / or reception unit provided in the communication unit in a preferred embodiment are preferably for the transmission or reception of such radio signals, e.g. B. as antennas, formed.
Bei dem Fahrzeug handelt es sich beispielsweise um ein Kraft- fahrzeug, wie Auto, Bus oder Lastkraftwagen, oder aber auch um ein Schienenfahrzeug, ein Schiff, ein Luftfahrzeug, wie Helikopter oder Flugzeug, oder um ein Fahrrad. 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 a bicycle.
In einer vorteilhaften Ausführungsform weist die Kommunikati- onseinrichtung Mittel zum Empfangen und Verarbeiten vonIn an advantageous embodiment, the communication device has means for receiving and processing
Lichtsignalen und/oder von Steuersignalen für die Leuchteinheit auf, insbesondere eine Kamera oder CCD-Matrix. Da die Leuchteinheit in Abstrahlrichtung der Leuchtmittel abschat- tungsfrei ist, können Lichtsignale von anderen Fahrzeugen mit entsprechenden Empfangsmitteln, wie Kamera oder CCD-Matrix, einfach empfangen und anschließend durch die in der Kommunikationseinrichtung enthaltene Datenverarbeitungseinheit verarbeitet werden, wobei die Datenverarbeitungseinheit hierfür vorzugsweise Mustererkennungsmittel aufweist. Light signals and / or control signals for the lighting unit, in particular a camera or CCD matrix. Because the Lighting unit in the direction of radiation of the lighting is schat- free, light signals from other vehicles with appropriate receiving means, such as camera or CCD matrix, can be easily received and then processed by the data processing unit contained in the communication device, the data processing unit preferably has pattern recognition means for this purpose.
Beispielsweise kann das Licht-Warnsignal eines vorausfahrenden oder entgegenkommenden Einsatzfahrzeugs detektiert und verarbeitet werden, vorzugsweise über die Mustererkennungsmittel der Datenverarbeitungseinheit. Anschließend kann die Kommunikationseinrichtung, falls Datenverarbeitungseinheit anhand des Lichtsignal-Musters ermittelt hat, dass es sich um ein Einsatzfahrzeug handelt, über ihren Signalausgang entsprechende Informationen, beispielsweise an das Steuergerät des Fahrzeugs weitergeben, so dass der Fahrer beispielsweise mittels einer entsprechenden Sprachausgabe aus dem Lautsprecher oder auf einer Anzeigeeinrichtung vor diesem Einsatzfahrzeug gewarnt und gebeten wird, an die Seite zu fahren. Insbesondere kann durch die Kommunikationseinrichtung ermittelt werden, aus welcher Richtung das Einsatzfahrzeug kommt, so dass auch diese Information, die für den Fahrer ohne weitere Hilfsmittel manchmal nicht so einfach erkennbar ist, schließlich an den Fahrer weitergegeben werden kann. Auf analoge Weise kann beispielsweise auch ermittelt werden, ob vorausfahrende Fahrzeuge unter Warnblinklicht fahren, so dass ein Stau frühzeitig erkannt werden kann. For example, the light warning signal of a preceding or oncoming emergency vehicle can be detected and processed, preferably via the pattern recognition means of the data processing unit. Subsequently, the communication device, if the data processing unit has determined based on the light signal pattern that it is an emergency vehicle, pass on their signal output corresponding information, for example to the control unit of the vehicle, so that the driver, for example by means of a corresponding voice output from the speaker or warned on a display device in front of this emergency vehicle and asked to drive to the side. In particular, it can be determined by the communication device from which direction the emergency vehicle comes, so that even this information, which is sometimes not so easily recognizable to the driver without further aids, can finally be passed on to the driver. In an analogous manner, it can also be determined, for example, whether vehicles driving in front drive under hazard warning lights so that a traffic jam can be detected early.
Als weitere Beispiele können die Informationen aus GPS und aus den Empfangsmitteln und/oder den Steuerleitungen der Leuchteinheit durch die Kommunikationseinheit in Kombination in der Form verarbeitet werden, dass durch die Mustererkennungsmittel zusammen mit den GPS-Informationen Ereignisse detektiert und diese mittels der Kommunikationseinheit versendet werden. So kann beispielsweise aus einem Blinksignal für das Rücklicht auf eine Notbremsung geschlossen werden, die zusätzlich als starke Verzögerung im GPS-Signal erkennbar i und entsprechend an die Umgebung versendet werden kann. Aus einem Blinksignal für beide BlinkerSeiten kann auf die Akti vierung eines Warnblinkers geschlossen werden. Zusammen mit der Geschwindigkeitsinformation aus GPS kann dann ermittelt werden, ob es sich um einen Stau (Fahrzeug bewegt sich bei Aktivierung des Warnblinkers) handelt, oder das Egofahrzeug liegen geblieben ist (Aktivierung des Warnblinkers bei stehendem Fahrzeug) , oder um ein Notbremsen (Aktivierung des Warnblinkers bei sehr starker Verzögerung des Egofahrzeugs) und anschließend kann die entsprechende Botschaft versendet werden. In ähnlicher Form ist die Erkennung und Versendung weiterer Ereignisse möglich. As further examples, the information from GPS and from the receiving means and / or the control lines of the lighting unit may be processed by the communication unit in combination in such a way that events are detected by the pattern recognition means together with the GPS information and sent via the communication unit. For example, it can be concluded from a flash signal for the tail light on an emergency stop, the In addition, as a strong delay in the GPS signal recognizable i and can be sent accordingly to the environment. From a flashing signal for both turn signals can be concluded on the Akti vation of a hazard warning lights. Together with the speed information from GPS can then be determined whether it is a congestion (vehicle moves when the hazard warning lights are activated), or the ego vehicle is left (activation of the hazard warning lights when the vehicle is stationary), or emergency braking (activation of the Hazard warning lights with very strong delay of the ego vehicle) and then the appropriate message can be sent. Similarly, the detection and sending of further events is possible.
Ferner kann die Kommunikationseinrichtung Steuersignale abgreifen, die über den Signaleingang zu der Leuchteinheit, beispielsweise vom Steuergerät des Fahrzeugs, übertragen werden, und, z. B. über die Sendeeinheit, diese Information zusätzlich über das Kommunikationsnetz und die oben angegebenen Funkkanäle an die Kommunikationseinrichtungen der anderen Fahrzeuge bzw. der Infrastruktur versenden. Hierfür ist vorzugsweise die Verbindung der Datenverarbeitungseinheit der Kommunikationseinrichtung mit dem Signaleingang bzw. dem Signalausgang der Leuchteinheit verwendbar. Dieses Vorgehen ist insbesondere dann sinnvoll, wenn es sich bei dem Fahrzeug um ein Einsatzfahrzeug handelt, das im Einsatz ist und daher unter einem Signallicht, z. B. Blaulicht, fährt. Furthermore, the communication device can pick up control signals that are transmitted via the signal input to the light unit, for example, from the control unit of the vehicle, and, for. B. via the transmitting unit, this information in addition to the communication network and the above-mentioned radio channels to the communication facilities of the other vehicles or the infrastructure. For this purpose, preferably the connection of the data processing unit of the communication device with the signal input or the signal output of the lighting unit can be used. This procedure is particularly useful if it is the vehicle is an emergency vehicle that is in use and therefore under a signal light, for. B. blue light, drives.
Es ist weiter von Vorteil, wenn die Kommunikationseinrichtung mit mindestens einem Leuchtmittel der Leuchteinheit verbindbar ist, und das mindestens eine Leuchtmittel, insbesondere mittels der Datenverarbeitungseinheit der Kommunikationseinrichtung, über entsprechende Steuersignale durch die Kommunikationseinrichtung betätigbar ist. Die Kommunikationseinrichtung kann hierdurch die Leuchteinheit direkt nutzen, um mit anderen Fahrzeugen oder der Infrastruktur zu kommunizieren. Wenn beispielsweise die Kommunikationseinrichtung bzw. eine andere Stelle des Fahrzeugs einen Stau erkannt hat, würde die Kommunikationseinrichtung direkt die Warnblink-Leuchtmittel der Leuchteinheit ansteuern und hierdurch das Warnblinklicht betätigen, so dass auch nachfolgende Fahrzeuge gewarnt werden können. Ferner kann, falls das Fahrzeug eine Notbremsung durchführen muss und die Kommunikationseinrichtung erkennt dies, durch die Leuchtmittel der Leuchteinrichtung eine besondere Leuchtfolge realisiert werden (emergency break light), mit welcher andere Fahrzeuge über die Notbremsung in- formiert werden können. It is further advantageous if the communication device can be connected to at least one light source of the light unit, and the at least one light source, in particular by means of the data processing unit of the communication device, can be actuated by the communication device via corresponding control signals. The communication device can thereby use the light unit directly to communicate with other vehicles or the infrastructure. For example, if the communication device or a another location of the vehicle has detected a traffic jam, the communication device would directly control the hazard warning lights of the light unit and thereby actuate the hazard warning lights, so that subsequent vehicles can be warned. Furthermore, if the vehicle must perform emergency braking and the communication device recognizes this, a special lighting sequence can be implemented by the lighting means of the lighting device (emergency break light) with which other vehicles can be informed about the emergency braking.
Hierbei sind im Zusammenhang mit der vorliegenden Erfindung Leuchtmittel alle elektrischen Betriebsmittel und elektrischen Verbraucher des Fahrzeugs, die dazu dienen, Licht zu erzeugen. Hierfür werden jeweils chemische und/oder physikalische Vorgänge genutzt. Jedes Leuchtmittel bildet eine Lichtguelle. Die Leuchtmittel umfassen Glühlampen, Gasentladungslampen, Leuchtdioden und Induktionslampen. Es ist ferner von Vorteil, wenn die Kommunikationseinrichtung eine Positionierungseinheit, vorzugsweise enthaltend einen GPS-Empfänger , aufweist. Hierdurch kann die Kommunikationseinrichtung autark arbeiten und beispielsweise Informationen über das umgebende Gelände, die Straßen, Kreuzungen und der- gleichen aus dem GPS-Empfänger mit Antenne zusammen mit in der Kommunikationseinrichtung in der Speichereinheit vorgesehenen Karten zur Verarbeitung der fahrzeugrelevanten Daten zur Verfügung stellen. An dieser Stelle sei darauf hingewiesen, dass im Kontext der vorliegenden Erfindung GPS stellvertretend für sämtliche globale Navigationssatellitensysteme (GNSS) steht, wie z. B. GPS, Galileo, Glonass (Russland), Compass (China), IRNSS (Indien) oder dergleichen. In the context of the present invention, illuminants are all electrical equipment and electrical consumers of the vehicle that serve to generate light. For this purpose, chemical and / or physical processes are used. Each light source forms a light source. The bulbs include incandescent lamps, gas discharge lamps, light emitting diodes and induction lamps. It is also advantageous if the communication device has a positioning unit, preferably containing a GPS receiver. As a result, the communication device can operate autonomously and provide, for example, information about the surrounding terrain, the roads, intersections and the like from the GPS receiver with antenna together with maps provided in the communication device in the memory unit for processing the vehicle-relevant data. It should be noted that in the context of the present invention GPS is representative of all global navigation satellite systems (GNSS) such. GPS, Galileo, Glonass (Russia), Compass (China), IRNSS (India) or the like.
Erfindungsgemäß kann die vorliegende Nachrüstlösung für eine Kommunikationseinrichtung in einer entsprechenden Speicher- einheit ein Zertifikat oder Zertifikate enthalten, die Informationen über diese Nachrüstlösung und/oder die Art der Nachrüstlösung und/oder die Einschränkungen der Nachrüstlösung umfassen. Die Kommunikationseinrichtung soll, wie vorstehend bereits beschrieben wurde, vorzugsweise nicht die gesamte Palette an Informations- und Sicherheitsdiensten beinhalten, die eine als Erstausrüstung ab Werk eingebaute Kommunikationseinrichtung beinhalten könnte (und welche dann ggf. an einem anderen Ort des Fahrzeugs verbaut wäre) . Die im Zusammen- hang mit der vorliegenden Anmeldung angedachte Kommunikationseinrichtung beinhaltet demgegenüber vorzugsweise lediglich einen beschränkten Funktionsumfang der an sich bekannten In- formations- und/oder Sicherheitsdienste der C2X-Kommunika- tion. Demnach ist es von Vorteil, wenn die anderen Teilnehmer des C2X-Systems, z. B. die umgebenden Fahrzeuge bzw. die Infrastruktur, darüber informiert sind, dass die Kommunikationseinrichtung der Nachrüstlösung den entsprechenden beschränkten Umfang aufweist, und welcher Art die Beschränkung des Funktionsumfangs ist. Die Fahrzeuge und die Infrastruktur können ferner über die Deklaration der Art der Nachrüstlösung ggf. erkennen, mit welchen Funktionsbeschränkungen diese behaftet ist. According to the invention, the present retrofit solution for a communication device in a corresponding memory contain a certificate or certificates containing information about this retrofit solution and / or the type of retrofit solution and / or the retrofit solution limitations. As has already been described above, the communication device should preferably not include the entire range of information and security services which could include a factory-installed as original equipment communication device (and which would then possibly installed in another location of the vehicle). In contrast, the communication device envisaged in connection with the present application preferably contains only a limited range of functions of the known information and / or security services of the C2X communication. Accordingly, it is advantageous if the other participants of the C2X system, z. B. the surrounding vehicles or the infrastructure, are informed that the communication device of the retrofit solution has the appropriate limited scope, and what is the limitation of the functional scope. The vehicles and the infrastructure may also recognize the functional limitations that may be involved by declaring the type of retrofit solution.
Die erfindungsgemäße Leuchteinheit weist ferner vorzugsweise mindestens einen Reflektor auf, wobei die Sendeeinheit und/ oder die Empfangseinheit und/oder die Mittel zum Empfangen von Lichtsignalen der Kommunikationseinrichtung innerhalb des mindestens einen Reflektors angeordnet ist. Innerhalb des Reflektors ist die Leuchteinheit nicht abgeschattet, so dass von dort Signale problemlos nach außen versendet werden können bzw. Signale von außen empfangen werden können. Der Signalempfang bzw. die Signalabgabe erfolgt dann jedoch bevorzugt in die Raumrichtung, die der Reflektor durch seinen Öffnungswinkel vorgibt. Eine 360 °-Abstrahlung bzw. ein 360°-Emp- fang von Informationen ist in vielen Fällen nämlich nicht unbedingt erforderlich, da insbesondere die vorausfahrenden oder nachfolgenden Fahrzeuge durch die Informationen der Kommunikationseinrichtung betroffen sind. The lighting unit according to the invention preferably further comprises at least one reflector, wherein the transmitting unit and / or the receiving unit and / or the means for receiving light signals of the communication device is arranged within the at least one reflector. Within the reflector, the lighting unit is not shaded, so that signals can be sent to the outside without problems or signals can be received from the outside. However, the signal reception or the signal output is then preferably in the spatial direction which the reflector specifies by its opening angle. In many cases, 360 ° radiation or 360 ° reception of information is not absolutely necessary, especially because of the preceding ones or subsequent vehicles are affected by the information of the communication device.

Gegebenenfalls kann auch eine der Schaltung des Drehknopfs entsprechende Dimmung des oder der Leuchtmittel ( s ) 10 erfolgen. Light unit 5 can be operated by the driver of the vehicle the, for example, the front and rear lights can be turned on by turning a knob to a specific, predetermined position. From the connected to the knob controller 20, the lighting unit then receives a signal to the effect that the at least one arranged in the lighting unit 5 illuminant 10 from the state "off" in the state "to" passes. Optionally, one of the circuit of the knob corresponding dimming of the lamp or (s) 10 can take place.
In der Leuchteinheit 5 ist ferner eine Kommunikationseinrichtung 30 vorgesehen, welche mit der Stromversorgungsleitung 14, 15 bzw. der Signalleitung 16 verbunden ist.

In the lighting unit 5, a communication device 30 is further provided, which is connected to the power supply line 14, 15 and the signal line 16. Accordingly, the signals transmitted to the communication device 30 via the signal line 16 from the operating elements or the control device 20 are thus likewise made available to the light-emitting means 10.

Ferner ist eine Positionierungseinheit 38, die beispielsweise als GPS- Empfänger ausgeführt ist, vorgesehen.

The transmitting unit 32, the receiving unit 34 and the positioning unit 38 are provided for the transmission or reception of radio data and have z. B. an antenna.
Die Kommunikationseinrichtung beinhaltet ferner eine Lichterfassungseinheit 37 wie eine CCD-Matrix oder eine Kamera zum Empfangen von Lichtsignalen, beispielsweise von vorausfahrenden Fahrzeugen. Die von der Lichterfassungseinheit 37 in elektrische Signale umgewandelten Lichtsignale werden dann an die Datenverarbeitungseinheit 36 zur Verarbeitung, beispielsweise durch die Mustererkennungsmittel analysiert und unter- sucht, ob es sich um fahrzeugrelevante Lichtsignale handelt. Beispielsweise kann so ein Warnblinklicht eines in Fahrtrichtung angeordneten Fahrzeugs oder eine Einsatzfahrt eines Ein- satzfahrzeugs, beispielsweise eines Krankenwagens, erkannt werden . The communication device further includes a light detection unit 37 such as a CCD matrix or a camera for receiving light signals, for example, from preceding vehicles. The light signals converted by the light detection unit 37 into electrical signals are then analyzed by the data processing unit 36 for processing, for example by the pattern recognition means, and it is examined whether they are vehicle-relevant light signals. For example, such a hazard warning light of a vehicle arranged in the direction of travel or a mission drive of an sentence vehicle, such as an ambulance, are detected.
Die Verwendung der erfindungsgemäßen Leuchteinheit bzw. der erfindungsgemäßen Kommunikationseinrichtung wird nachfolgend anhand von Beispielen beschrieben: The use of the lighting unit according to the invention or of the communication device according to the invention is described below by means of examples:
1. Beispiel : 1st example:
Das Fahrzeug leitet eine Notbremsung ein. Dies wird von dem Steuergerät 20 des Fahrzeugs auch der Kommunikationseinrichtung 30 über die Signalleitung 16 mitgeteilt. Die Datenverarbeitungseinheit 36 der Kommunikationseinrichtung 30 veranlasst daraufhin die Aussendung einer vorgegebenen, besonderen Leuchtfolge durch das mindestens eine Leuchtmittel 10. Die Daten hierfür werden von der Kommunikationseinrichtung 30 an das/die Leuchtmittel 10 über die Signalleitung 16 übertragen. Zusätzlich kann ggf. eine Versendung von entsprechenden Warninformationen über den/die Funkkanäle mittels Sendeeinheit 32 erfolgen. Die vorausfahrenden und nachfolgenden Fahrzeuge können daher sehr schnell erkennen, dass das Fahrzeug eine The vehicle initiates emergency braking. This is communicated by the control unit 20 of the vehicle and the communication device 30 via the signal line 16. The data processing unit 36 of the communication device 30 then initiates the transmission of a predetermined, special luminous sequence by the at least one luminous means 10. The data for this purpose are transmitted by the communication device 30 to the / the illuminant 10 via the signal line 16. In addition, a transmission of corresponding warning information about the radio channel (s) may be effected by means of transmitting unit (32), if necessary. The preceding and following vehicles can therefore very quickly recognize that the vehicle has a
Notbremsung durchführt, und entsprechend reagieren. Insbesondere können auch aufgrund der besonderen Leuchtfolge die Fahrer der noch nicht mit einer derartigen Kommunikationseinrichtung ausgerüsteten Fahrzeuge visuell erkennen, dass das Fahrzeug notbremsen muss. Emergency braking, and react accordingly. In particular, due to the particular lighting sequence, the drivers of the vehicles not yet equipped with such a communication device can visually recognize that the vehicle must emergency brake.
2. Beispiel : 2nd example:
Analog zu Beispiel 1 kann durch die Kommunikationseinrichtung das Warnblinken der Leuchtmittel 10 gestartet werden, wenn das Fahrzeug aufgrund eines technischen Defekts liegen bleibt. Zusätzlich kann analog zu Beispiel 1 die Versendung von entsprechenden Warninformationen einschließlich des Standorts des Fahrzeugs, der mittels der Positionierungseinheit 38 bestimmt wurde, über den Funkkanal oder die Funkkanä- le mittels der Sendeeinheit 32 erfolgen. 3. Beispiel : Analogous to Example 1, the warning device of the lighting means 10 can be started by the communication device when the vehicle remains due to a technical defect. In addition, similar to example 1, the transmission of corresponding warning information including the location of the vehicle, which was determined by means of the positioning unit 38, can take place via the radio channel or the radio channels by means of the transmitting unit 32. 3rd example:
Bei einem vorausliegenden Stau in Fahrtrichtung kann das Fahrzeug diesen sehr schnell erkennen, da die Lichterfassungseinheit 37 Warnblinklicht-Signale der vorausfahrenden Fahrzeuge empfängt und diese an die Datenverarbeitungseinheit 36 weiterleitet. Durch die integrierten Mustererkennungsmittel stellt die Kommunikationseinrichtung 30 fest, dass es sich um ein Warnblinklicht handelt, so dass die Datenverarbeitungseinheit 36 dann an den Fahrer die Staugefahr bei- spielsweise mittels einer Sprachnachricht über die Lautsprecher des Fahrzeuge weitergibt. Nach Erkennen eines Staus kann durch die Kommunikationseinrichtung 30 entsprechend auch das mindestens eine Leuchtmittel 10 derart angesteuert werden, dass dieses Warnblinklicht aussendet und die nachfolgenden Fahrzeuge so über den Stau unabhängig von einer Funkverbindung mit ihnen informiert .  If there is a traffic jam ahead, the vehicle can detect it very quickly, since the light detection unit 37 receives warning flashing light signals from the vehicles in front and forwards them to the data processing unit 36. As a result of the integrated pattern recognition means, the communication device 30 determines that it is a hazard warning light, so that the data processing unit 36 then forwards the congestion hazard to the driver, for example by means of a voice message via the loudspeakers of the vehicle. After detecting a jam, the at least one light-emitting means 10 can also be controlled by the communication device 30 in such a way that it emits the hazard warning light and informs the following vehicles of the jam independently of a radio link with them.
4. Beispiel : 4th example:
Ein Einsatzfahrzeug enthält die Sendeeinheit 34, die Emp- fangseinheit 32 und/oder die Lichterfassungseinheit 37 der erfindungsgemäßen Kommunikationseinrichtung 30 in einer Leuchteinheit 5 in Form einer Rundumkennleuchte innerhalb des Reflektors 12 (siehe Fig. 2) . Da sich die Rundumkennleuchte während des Aussendens des Einsatz-Signals dreht, können hier entsprechende Informationen von der Kommunikationseinrichtung 30 während der Drehung des Reflektors um 360° auch in alle Richtungen der Rotationsebene versandt bzw. empfangen werden.  A deployment vehicle contains the transmission unit 34, the reception unit 32 and / or the light detection unit 37 of the communication device 30 according to the invention in a lighting unit 5 in the form of a rotating beacon within the reflector 12 (see FIG. 2). Since the rotating beacon rotates during the transmission of the insert signal, corresponding information can be sent or received by the communication device 30 during the rotation of the reflector through 360 ° in all directions of the rotation plane.
5. Beispiel : 5th example:
