Fahrzeug, insbesondere Hybridfahrzeug, mit einer elektrischen EinrichtungVehicle, in particular hybrid vehicle, with an electrical device
Die Erfindung betrifft ein Fahrzeug, insbesondere Hybridfahrzeug, mit einer elektrischen Einrichtung, die eine für die Berührung durch eine Person unzulässig hohe Spannungshöhe aufweist.The invention relates to a vehicle, in particular hybrid vehicle, with an electrical device which has an impermissibly high voltage level for contact by a person.
Die Erfindung betrifft ferner ein Verfahren zur Warnung vor einer solchen un- zulässig hohen elektrischen Spannung bei einem Fahrzeug.The invention further relates to a method for warning against such an unacceptably high electrical voltage in a vehicle.
Stand der TechnikState of the art
Im Stand der Technik sind Fahrzeuge bekannt, insbesondere Elektro- und/oder Hybridfahrzeuge, die elektrische Einrichtungen aufweisen, die eine für die Berührung durch eine Person unzulässig hohe Spannung führen. Derartige elektrische Einrichtungen sind beispielsweise als Hochvolt-Systeme bekannt, also solche, die eine Spannung über 60V DC oder 25V AC aufweisen, so dass sie im Sinne von ISO 6469 als gefährlich gelten. Derart hohe Spannungen sind in sol- chen Einrichtungen aber erforderlich, um die für eine bestimmte, geforderte Leistung erforderliche Stromstärke gering halten zu können, damit unnötig große Leiterquerschnitte und damit ein unnötig hohes Gewicht vermieden werden können.Vehicles are known in the prior art, in particular electric and / or hybrid vehicles, which have electrical devices which carry an unacceptably high voltage for contact by a person. Such electrical devices are known, for example, as high-voltage systems, ie those which have a voltage greater than 60V DC or 25V AC, so that they are considered dangerous in the sense of ISO 6469. However, such high voltages are required in such devices in order to be able to keep the current intensity required for a specific, required power low, so that unnecessarily large conductor cross sections and thus an unnecessarily high weight can be avoided.
Personen werden gegen indirektes Berühren, insbesondere im Fehlerfall, solcher unter Hochspannung stehender Teile durch zusätzliche Basisisolationen, zusätzliche Abdeckungen und eine galvanische Trennung der Hochvolt-Netze von Niedervolt-Netzen, insbesondere Bordspannungsnetzen, geschützt. Ferner werden periodische oder kontinuierliche Isolationsüberwachungen und Fehlerstromüber- wachungen mit Abschaltung solcher Hochspannungsnetze als zusätzliche funktionale Maßnahmen eingesetzt. Im Fall einer galvanischen Trennung von Hoch- volt-Netz und Niedervolt-Netz besteht erst ab zwei Isolationsfehlern eine Gefährdung durch indirektes Berühren, wenn beispielsweise ein Gehäuse durch einen Fehler auf Hochvolt-Plus und die Karosserie durch einen zweiten Fehler auf Hochvolt-Minus liegt. Die einschlägige Norm erfordert in diesem Fall, die Energie im Hochvolt-Netz innerhalb von zwei Sekunden abzubauen, beispielsweise durchPersons are protected against indirect contact, especially in the event of a fault, such parts under high voltage by additional basic insulation, additional covers and galvanic isolation of the high-voltage networks of low-voltage networks, especially on-board networks. Furthermore, periodic or continuous insulation monitoring and fault current monitoring with the disconnection of such high-voltage networks are used as additional functional measures. In the case of galvanic isolation of high- volt-Netz and low-voltage network is only from two insulation faults endangerment by indirect contact, for example, if a housing is due to a fault on high-voltage plus and the body by a second error on high-voltage minus. The relevant standard in this case requires that the energy in the high-voltage network be reduced within two seconds, for example by
Trennung der Hochvolt-Batterie und Entladung der Energie-Zwischenspeicher. Aus der DE 10 2006 016 137.8 ist eine Steckvorrichtung zur Kontaktierung der Hochspannungsbaugruppe eines Hybridfahrzeugs sowie eine Hochspannungsbaugruppe eines Hybridfahrzeugs bekannt, die mittels eines Steuerkontaktes in der Steckvorrichtung eine Spannungsfreischaltung erreichen, wenn ein Fehler auftritt.Separation of the high-voltage battery and discharge of the energy buffer. From DE 10 2006 016 137.8 a plug-in device for contacting the high voltage assembly of a hybrid vehicle and a high voltage assembly of a hybrid vehicle is known, which reach a voltage release by means of a control contact in the plug device, if an error occurs.
Daran ist nachteilig, dass eine entsprechende Trennung der Steckvorrichtung, insbesondere des Steuerkontaktes, sowie die Funktion weiterer, vorstehend be- schriebener funktionaler Maßnahmen, unter ungünstigen Umständen bei einemIt is disadvantageous that a corresponding separation of the plug-in device, in particular of the control contact, as well as the function of further functional measures described above, under unfavorable circumstances in a
Unfall nicht funktionieren, weil beispielsweise Verklemmungen oder Beschädigungen einer solchen Art eingetreten sind, dass die diesen Schutz bewirkenden funktionalen Elemente außer Funktion gesetzt sind. Unter ungünstigen Umständen ist es in solchen Fällen möglich, dass die funktionalen Maßnahmen zum Abbau der Energie im Hochvolt-Netz nicht umgesetzt werden können und dass gleichzeitig ein doppelter Isolationsfehler vorliegt. In solchen Fällen besteht für Personen, insbesondere Rettungskräfte, bei Kontakt mit der Karosserie eine Gefährdung durch Hochspannung der elektrischen Einrichtung des Fahrzeugs. Eine solche Gefährdung ist von außen nicht erkennbar.Accident does not work because, for example, jamming or damage have occurred in such a way that the protective elements causing this functional elements are disabled. Under unfavorable circumstances, it is possible in such cases that the functional measures for reducing the energy in the high-voltage network can not be implemented and that at the same time there is a double insulation fault. In such cases, there is a risk for persons, in particular rescue workers, when in contact with the body by high voltage of the electrical device of the vehicle. Such a threat is not recognizable from the outside.
Aufgabe der Erfindung ist es, Personen, insbesondere Rettungskräfte, durch von außen erkennbare Warnungen vor Schäden durch Kontakt mit fehlerhaften elektrischen Einrichtungen/Hochvolt-Netzen schadhafter oder verunfallter Fahrzeuge zu bewahren.The object of the invention is to protect persons, in particular rescue workers, from externally recognizable warnings from damage caused by contact with faulty electrical equipment / high-voltage networks of damaged or accident-damaged vehicles.
Offenbarung der ErfindungDisclosure of the invention
Hierzu wird ein Fahrzeug, insbesondere Hybridfahrzeug, mit einer elektrischen Einrichtung vorgeschlagen, die eine für die Berührung durch eine Person un- zulässig hohe Spannung aufweist, wobei vorgesehen ist, dass dieses Fahrzeug einen im Falle eines Unfalles ansprechenden Meldesensor aufweist, der an eine Warneinrichtung zur Signalisierung der Spannungshöhe angeschlossen ist. Kommt es demzufolge zu einem Unfall mit dem Fahrzeug, spricht der Meldesensor an, wodurch die angeschlossene Warneinrichtung die Spannungshöhe signalisiert. Als Meldesensoren kommen sämtliche Sensoren in Betracht, die un- falltypische Konstellationen detektieren, die im normalen Fahrbetrieb des Fahrzeugs nicht vorkommen.For this purpose, a vehicle, in particular a hybrid vehicle, is proposed with an electrical device which has an unacceptably high voltage for contact by a person, it being provided that this vehicle has an alarm sensor which responds in the event of an accident and which is connected to a vehicle Warning device is connected to signal the voltage level. Consequently, if an accident occurs with the vehicle, the message sensor responds, causing the connected warning device to signal the voltage level. As a detection sensors, all sensors come into consideration, the accident-typical constellations detect that do not occur in normal driving the vehicle.
In einer Ausführungsform weist der Meldesensor einen Beschleunigungssensor auf. Der Meldesensor selbst kann hierbei als Baugruppe von mehreren, ins- besondere mehreren unterschiedlichen Sensoren ausgebildet sein. Bevorzugt weist er hierbei einen Beschleunigungssensor auf, der auf im regulären Fahrbetrieb unübliche Beschleunigungen, nämlich Beschleunigungswerte und -richtungen, prüft. Sinnvollerweise wird auf solche Beschleunigungen geprüft, die als hinreichende Bedingung für einen Unfall gelten können.In one embodiment, the message sensor has an acceleration sensor. The message sensor itself can hereby be designed as an assembly of several, in particular a plurality of different sensors. In this case, it preferably has an acceleration sensor which checks for accelerations which are unusual in normal driving operation, namely acceleration values and directions. It makes sense to check for accelerations that can be regarded as a sufficient condition for an accident.
Bevorzugt weist der Meldesensor einen Airbagsensor auf. Airbagsensoren erden in modernen Automobilen ohnehin verwendet und können ohne Weiteres an die Warneinrichtung angeschlossen beziehungsweise dem Meldesensor zugeordnet oder in diesen integriert werden.The message sensor preferably has an airbag sensor. Airbag sensors ground used in modern automobiles anyway and can be easily connected to the warning device or associated with the alarm sensor or integrated into this.
Besonders bevorzugt ist vorgesehen, dass der Meldesensor ein Element einer Airbagsteuerung ist. Der Meldesensor wird demzufolge in die Airbagsteuerung integriert, nicht umgekehrt Sensoren der Airbagsteuerung beziehungsweise Airbagsensoren in den Meldesensor. Der Meldesensor ist demzufolge der Airbagsteuerung zugeordnet, bevorzugt in diese integriert, und nutzt die Airbagsteuerung zur Erkennung und Auswertung von unfalltypischen Parametern.It is particularly preferred that the message sensor is an element of an airbag control. The message sensor is therefore integrated into the airbag control, not the other way round sensors of the airbag control or airbag sensors in the message sensor. The message sensor is therefore associated with the airbag control, preferably integrated into it, and uses the airbag control for the detection and evaluation of typical accident parameters.
Die Warneinrichtung gibt bevorzugt ein visuelles, akustisches und/oder haptisches Signal aus. Visuelle Signale sind beispielsweise Blink- oder all- gemeine Lichtsignale von oder an vorhandenen oder auch eigens hierfür vorgesehen visuellen Signalisierungseinrichtungen. Akustische Signale sind mit dem Hörsinn wahrzunehmende Signale, die insbesondere über im Fahrzeug vorhandene Signalisierungseinrichtungen, beispielsweise Hörner, oder eigens hierfür vorgesehene akustische Geber ausgesendet werden und gegenüber den visu- eilen Signalen den Vorzug der Omnidirektionalität haben, die keine Aufmerksamkeit von sich nähernden Personen erfordert. Haptische Signale kommen insbe- sondere als Rüttelsignale oder ähnliche über den Tastsinn wahrnehmbare Signale in Betracht, wie sie beispielsweise über eine Exzentervorrichtung ausgegeben werden können. Insbesondere ist gerade bei den visuellen Signalen auch vorgesehen, Klartextmeldungen auszugeben beziehungsweise Meldungen in Symbol- form, beispielsweise aufleuchtende, blitzförmige Piktogramme, wie sie allgemein bekannt sind und allgemein verständlich auf hohe Spannung hinweisen.The warning device preferably outputs a visual, acoustic and / or haptic signal. Visual signals are, for example, flashing or general light signals from or to existing visual signaling devices or else provided specifically for this purpose. Acoustic signals are signals to be perceived with the sense of hearing which are transmitted, in particular, via signaling devices present in the vehicle, for example horns, or specially provided acoustic transmitters, and which have the advantage of omnidirectionality compared with the visual signals which requires no attention from approaching persons. Haptic signals are mainly special as Rüttelsignale or similar perceptible via the sense of touch signals into consideration, as they can be output, for example via an eccentric. In particular, it is also provided in the case of visual signals to output plain text messages or messages in symbol form, for example, flashing, lightning-shaped pictograms, as are generally known and generally understandably indicate high voltage.
Weiter wird ein Verfahren vorgeschlagen zur Warnung vor einer unzulässig hohen elektrischen Spannung bei einem Fahrzeug, insbesondere Hybridfahr- zeug, vorzugsweise wie in vorstehenden Ausführungsformen beschrieben, wobei das Fahrzeug eine elektrische Einrichtung aufweist, die eine für die Berührung durch eine Person unzulässig hohe Spannungshöher aufweist. Hierbei ist vorgesehen, dass im Falle eines Unfalls dessen Sensierung erfolgt und eine Warnmeldung abgegeben wird, die vor der unzulässig hohen Spannung warnt. Die Sensierung erfolgt bevorzugt wie aus vorstehend beschriebenen Ausführungsbeispielen ersichtlich und führt zur Ausgabe der Warnmeldung, die sich nähernde Personen, insbesondere Rettungspersonal, auf die Gefahr einer hohen elektrischen Spannung aufmerksam macht und veranlasst, entsprechende Schutzvorkehrungen zu treffen.Furthermore, a method is proposed for warning against an inadmissibly high electrical voltage in a vehicle, in particular hybrid vehicle, preferably as described in the preceding embodiments, the vehicle having an electrical device which has an impermissibly high voltage level for contact by a person. In this case, it is provided that in the event of an accident, the sensor is sensed and a warning message is issued warning of the inadmissibly high voltage. The sensing is preferably carried out as described above embodiments and leads to the output of the warning message that makes approaching people, especially rescue personnel, aware of the risk of high electrical voltage and causes to take appropriate precautions.
