Description
Die Erfindung befaßt sich mit Verfahren und mit Vorrichtungen zur Alarmierung bei Fahrzeugunfällen. Eine Alarmierung von Hilfsdiensten wie beispielsweise die Polizei, die Feuerwehr oder den Krankendienst ist bei Fahrzeugunfällen von besonderer Bedeutung. Bei dieser Alarmierung kommt es insbesondere auf eine möglichst schnelle Alarmierung nach dem Unfall an.The invention is concerned with methods and devices for alarming in vehicle accidents. Alerting of auxiliary services such as the police, fire brigade or health service is in vehicle accidents really important. This alarm comes in particular alert as quickly as possible after the accident.
Bekannt ist bisher die Alarmierung der Hilfsdienste mittels Telefon oder Funk durch vorbeifahrende Verkehrsteilnehmer, welche durch die Straßenverkehrsordnung gefordert sind, an einem Unfall anzuhalten und Hilfe z. B. durch Alarmierung zu leisten. Dieser Verpflichtung wird aber nur sehr widerwillig und nur in begrenztem Umfang gefolgt, so daß einige, zum Teil lebenswichtige Zeit vergeht, bis die notwendige Alarmierung erfolgt. Insbesondere ist diese Alarmierung von der Anwesenheit von unbeteiligten Verkehrsteilnehmern oder von nur gering verletzten Verunfallten abhängig, da grundsätzlich nur ein solcher einen Alarm absetzen kann. Dies führt zu erheblichen Unsicherheiten bei der Alarmierung, die das Leben der Verunfallten kosten kann.Up to now, the alerting of the auxiliary services by telephone or radio has been known by passing road users, who are by the Road traffic regulations are required to stop an accident and get help e.g. B. to perform by alarm. But this obligation only becomes very reluctantly and followed only to a limited extent, so some, in part vital time passes until the necessary alarm is given. In particular, this alerting of the presence of uninvolved Dependent on road users or only slightly injured, because in principle only one of these can set off an alarm. this leads to significant uncertainties in alerting the life of the Accidents can cost.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Alarmierung sicherzustellen, die eine schnelle und sichere Alarmierung gewährleistet.The present invention has for its object an alarm ensure a quick and safe alarm.
Diese Aufgabe wird gelöst durch das Verfahren zur Alarmierung mit den im Anspruch 1 angegebenen Merkmalen, sowie durch die Vorrichtung mit den im Anspruch 7 angebenden Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This task is solved by the procedure for alarming with the Features specified claim 1, and by the device with the in Claim 7 indicating features. Advantageous further developments of Invention are the subject of the dependent claims.
Die Erfindung gewährleistet eine unverzügliche und sichere Alarmierung, da erfindungsgemäß bei Überschreiten der Schwere eines Unfalls, die sich beispielsweise aus dem Maß der Fahrzeugverformung oder den Verzögerungswerten beim Unfall bestimmt, über einen vorab bestimmten Grenzwert automatisch ohne Zwischenschaltung von menschlichen Entscheidungsprozessen ein Alarmsignal abgegeben wird. Damit wird eine zeitoptimierte Alarmierung sichergestellt, die eine bestmögliche Rettung der Verunfallten gewährleistet.The invention ensures an immediate and safe alarm, because According to the invention when the severity of an accident is exceeded, the for example from the degree of vehicle deformation or the Deceleration values determined in the accident, over a predetermined Limit value automatically without the interposition of human Decision processes are given an alarm signal. So that becomes a Time-optimized alarming ensured that the best possible rescue of the Accident guaranteed.
Als besonders geeignet erweist sich, ohne Einschränkung auf diese Möglichkeiten der Positionsbestimmung, mittels eines GPS-Systems, eines Navigationssystems, einer Richtfunkeinheit oder mittels einer Sendeanstaltenanalyse die Position des Fahrzeuges zu bestimmen und diese im Rahmen des Alarmes direkt an die Hilfsdienste zu senden. Durch diese Ausbildung ist ein sicheres und schnelles Auffinden und Erreichen des Unfallortes möglich, was die Versorgung der Verunfallten stark verbessert. It proves to be particularly suitable, without being restricted to these Possibilities of positioning, using a GPS system, one Navigation system, a directional radio unit or by means of a Broadcasters analysis to determine the position of the vehicle and this to be sent directly to the emergency services as part of the alarm. Through this Training is a safe and quick way to find and achieve the Accident location possible, which greatly improves the care of the casualty.
Gelingt es gegebenenfalls neben der Position auch noch die Anzahl der Fahrzeuginsassen oder eine Information über die Unfallschwere zu übermitteln, erhält der oder die Hilfsdienste weitere wichtige Informationen, um sich vorab ein detailliertes Bild über den Umfang der benötigten Hilfe - wie z. B. Anzahl der Krankenwagen - zu machen. Die Anzahl der Fahrzeuginsassen kann mit Hilfe einer Eingabeeinheit z. B. in Form eines Ziffernfeldes durch den Fahrzeugführer eingegeben werden oder durch eine Sitzerkennung automatisch bestimmt werden. Diese Sitzerkennung kann mit Hilfe von Drucksensoren erfolgen. Diese zusätzliche Übermittlung der Anzahl der Fahrzeuginsassen ermöglicht eine noch bessere und damit gegebenenfalls schnellere Hilfe, wodurch Menschenleben gerettet werden können.If necessary, besides the position, the number of Vehicle occupants or information about the severity of the accident forward, the service provider (s) will receive further important information in order to get a detailed picture in advance of the scope of the help needed - such as B. Number of ambulances - to be made. The number of vehicle occupants can with the help of an input unit z. B. in the form of a number field by the Vehicle drivers can be entered or through a seat recognition can be determined automatically. This seat detection can be done with the help of Pressure sensors take place. This additional transmission of the number of Vehicle occupants enables an even better and thus possibly faster help, which can save lives.
Zur Bestimmung der Schwere des Unfalls stehen verschiedene geeignete Möglichkeiten zur Verfügung, solche, die auf das Maß der Verformung des Fahrzeuges beruhen, oder solche, die eine Analyse der Beschleunigung oder Verzögerung des Fahrzeugs verwenden. Hat ein Fahrzeug, wie es zumeist serienmäßig der Fall ist, einen Airbag oder Gurtstraffer eingebaut, so kann dessen Auslösen, welches ebenfalls von der Schwere des Unfalls abhängt, zugleich die automatische Alarmierung bewirken. Bei dieser vorteilhaften Anordnung kann auf eine separate Auswerteschaltung mit Beschleunigungsaufnehmer oder Verformungsaufnehmer oder ähnliches verzichtet werden, was sich positiv auf die Störanfälligkeit und die Gerätekosten auswirkt.There are various suitable ways of determining the severity of the accident Possibilities available, those based on the degree of deformation of the Vehicle based, or those that have an analysis of acceleration or Use vehicle deceleration. Has a vehicle like it usually does the case is standard, an airbag or belt tensioner installed, so can its triggering, which also depends on the severity of the accident, also cause the automatic alarm. In this advantageous Arrangement can be made using a separate evaluation circuit Accelerometers or deformation sensors or the like be dispensed with, which positively affects the susceptibility to faults and the Device costs.
Ohne Beschränkung auf Telefon und Funkgerät sind diese Mittel zum Alarmieren besonders geeignet, da sie häufig zur Ausstattung von Kraftfahrzeugen gehören. Dabei ist die Ausstattungshäufigkeit insbesondere bei den beruflich häufig im Verkehr benutzten und damit besonders unfallgefährdeten Fahrzeugen vorteilhafterweise besonders hoch. Da diese, wie bereits ausgeführt, zur Grundausstattung gehören und an ein fahrzeuginternes Bussystem, wie z. B. das D2B-Optical-Bussystem, angeschlossen sind, wird durch die ebenfalls an dieses Bussystem angeschlossenen anderen Komponenten der erfindungsgemäßen Vorrichtung eine einfache, im Fahrzeug günstig anzuordnende und sicher zu verschaltende Ausführung erreicht.Without limitation to telephone and radio, these means are for Alarming is particularly suitable since it is often used to equip Motor vehicles belong. The equipment frequency is particularly important among those who are frequently used in traffic for work and thus particularly vehicles at risk of accidents advantageously particularly high. This one, as already mentioned, belong to the basic equipment and to one in-vehicle bus system, such as B. the D2B optical bus system, are also connected to this bus system connected other components of the device according to the invention a simple, easy to arrange in the vehicle and safe to connect Execution reached.
Als sehr geeignet hat sich erwiesen, einen Energiespeicher vorzusehen welcher unabhängig von dem Energienetz des Fahrzeugs ist, durch den eine Alarmierung auch bei zusammengebrochenem Energienetz des Fahrzeuges gewährleistet ist. Beispiele für einen derartigen Energiespeicher sind Akkumulatoren, Batterien oder ähnliches. Darüberhinaus erwiest es sich als vorteilhaft, die Unfalldaten in einem vorzugsweise nicht flüchtigen Speicher abzulegen, damit aus diesem die notwendigen Informationen einerseits für die Alarmierung und andererseits für eine Unfallanalyse durch Verkehrssachverständige ausgelesen werden können. It has proven to be very suitable to provide an energy store which is independent of the vehicle's energy network through which one Alerting even if the vehicle's power grid has collapsed is guaranteed. Examples of such an energy store are Accumulators, batteries or the like. Furthermore, it turns out to be advantageous, the accident data in a preferably non-volatile memory filing, so that the necessary information on the one hand for the Alerting and on the other hand for an accident analysis Traffic experts can be read out.
Weiterhin ist es möglich, neben den üblichen Hilfsdiensten, wie Polizei, Feuerwehr und Krankenwagen, auch Verkehrswarnzentralen oder Rundfunkstationen, sowie, was sich als besonders vorteilhaft erweist, auch die Fahrzeuglenker in der Umgebung des Fahrzeuges über den Unfall zu alarmieren. Insbesondere die Alarmierung der Fahrzeugführer in der Umgebung gewährleistet im Hinblick auf Folgeunfälle - Auffahren auf einen bestehenden Unfall - eine erhöhte Sicherheit für die Verunfallten, da sie nicht Opfer eines Folgeunfalls werden können.In addition to the usual support services such as the police, Fire brigade and ambulance, also traffic warning centers or Broadcast stations, as well as, which proves to be particularly advantageous, the Vehicle drivers in the area surrounding the vehicle about the accident alert. In particular, alerting drivers in the Environment guarantees with regard to secondary accidents - collision with one existing accident - increased safety for the casualty since they are not Can be the victim of a subsequent accident.
Ein Ausführungsbeispiel der Erfindung ist in den Abbildungen dargestellt.An embodiment of the invention is shown in the figures.
Abb. 1 zeigt ein Blockschaltbild einer erfindungsgemäßen Vorrichtung. Fig. 1 shows a block diagram of a device according to the invention.
Abb. 2 zeigt den schematischen Aufbau der Vorrichtung mittels eines D2B-Optical-Bussystems. Fig. 2 shows the schematic structure of the device using a D2B optical bus system.
Wie in Abb. 1 dargestellt, besteht die Vorrichtung zum Alarmieren über Verkehrsunfälle aus einem Crash-Sensor, einem GPS-Empfänger, einer Systemsteuerung und einem Telefon. Der Crash-Sensor ermittelt aufgrund der Auswertung eines Beschleunigungssignals die Schwere des Unfalls und zündet bei Überschreiten eines definierten Grenzwertes den ebenso dargestellten Airbag. Bei Überschreiten eines nicht notwendigerweise gleichen Grenzwertes wird an die Systemsteuerung ein Crashsignal übermittelt. Dadurch wird die stets vom GPS-Empfänger bestimmte und an die Systemsteuerung übermittelte aktuelle Position des Fahrzeuges sowie die durch die Sitzplatzerkennung festgestellte Insassenzahl mit einer fahrzeugangepaßten Alarmmeldung, beispielsweise "Mercedes C200 mit 3 Insassen besetzt an der Position XY verunfallt", automatisch an die Hilfsdienste oder an eine einzelne Alarmzentrale mittels Telefon übermittelt. Dabei ist die Alarmmeldung sowie die Rufnummer des Hilfsdienstes in einem Speicher in der Systemsteuerung abgelegt.As shown in Fig. 1, the device for alarming traffic accidents consists of a crash sensor, a GPS receiver, a system control and a telephone. The crash sensor determines the severity of the accident on the basis of the evaluation of an acceleration signal and, if a defined limit value is exceeded, ignites the airbag which is also shown. If a limit value that is not necessarily the same is exceeded, a crash signal is transmitted to the system control. As a result, the current position of the vehicle, which is always determined by the GPS receiver and transmitted to the system control, as well as the number of occupants determined by the seat recognition with an alarm message adapted to the vehicle, for example "Mercedes C200 with 3 occupants occupied at position XY" is automatically sent to the emergency services or transmitted to a single alarm center by telephone. The alarm message and the number of the emergency service are stored in a memory in the system control.
In Abb. 2 ist das D2B-Optical-Bussystem dargestellt, welches als Komponenten die Sitzplatzerkennung, den Crash-Sensor, den GPS- Empfänger, die Systemsteuerung sowie das Telefon aufweist. Durch dieses Bussystem werden die notwendigen Informationen zwischen den einzelnen Komponenten übermittelt. Dabei können die einzelnen Komponenten an beliebigen Positionen des Fahrzeuges angeordnet sein, wobei die jeweiligen Positionen nach der jeweiligen optimalen Funktionalität bestimmt werden können, d. h. die Systemsteuerung kann als Black Box irgendwo im Fahrzeug, beispielsweise unter dem Fahrersitz oder im Kofferraum, wo sie nicht stört, angeordnet sein. Fig. 2 shows the D2B optical bus system, which has components such as seat recognition, the crash sensor, the GPS receiver, the system control and the telephone. This bus system transmits the necessary information between the individual components. The individual components can be arranged at any position of the vehicle, the respective positions can be determined according to the respective optimal functionality, ie the system control can be located anywhere in the vehicle as a black box, for example under the driver's seat or in the trunk, where it does not interfere. be arranged.
