Abstract
Description
Die Erfindung betrifft ein Verfahren zur Aktivierung von Insassenschutzschutzsystemen eines Fahrzeugs.The The invention relates to a method for activating occupant protection systems of a vehicle.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Verfahren zur Aktivierung von Insassenschutzschutzsystemen eines Fahrzeugs anzugeben.Of the Invention is based on the object, an improved method for activating occupant protection systems of a vehicle specify.
Die Aufgabe wird erfindungsgemäß mit einem Verfahren gelöst, welches die im Anspruch 1 angegebenen Merkmale aufweist.The Object is according to the invention with a method solved, which specified in claim 1 features having.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous Embodiments of the invention are the subject of the dependent claims.
Bei dem erfindungsgemäßen Verfahren zur Aktivierung von Insassenschutzsystemen eines Fahrzeugs wird eine Wahrscheinlichkeit eines Überschlagereignisses des Fahrzeugs anhand einer Erfassungseinrichtung bestimmt, wobei ab einem vorgegebenen Schwellwert der Wahrscheinlichkeit vor einem Überschlagereignis des Fahrzeugs reversible Insassenschutzmittel mittels einer Steuereinheit aktiviert werden.at the inventive method for activation occupant protection systems of a vehicle becomes a probability a rollover event of the vehicle based on a Detection device determines, starting from a predetermined threshold the probability of a rollover event of the Vehicle reversible occupant protection means by means of a control unit to be activated.
Im Detail ist die Erfassungseinrichtung beispielsweise als Airbag-Steuergerät ausgeführt, welche anhand eines Drehwinkels und einer Drehwinkelgeschwindigkeit des Fahrzeugs die Wahrscheinlichkeit des Überschlagereignisses bestimmt. Ab einem bestimmten Schwellwert der Wahrscheinlichkeit werden reversible Insassenschutzmittel, z. B. Gurtstraffer, aktive Kopfstützen und/oder Überrollbügel, auch vor dem Eintreten eines Überschlages in Betrieb gesetzt.in the Detail is the detection device, for example, as an airbag control unit executed, which on the basis of a rotation angle and a rotational angular velocity the vehicle the probability of the rollover event certainly. From a certain threshold of probability be reversible occupant protection, z. B. belt tensioner, active Headrests and / or roll bars, also available the occurrence of a rollover in operation.
Als reversibel wird in der vorliegenden Erfindung ein Insassenschutzmittel verstanden, das mehrmals durch eine Aktivierung von einem Ausgangszustand in einen Wirkzustand versetzt und durch Deaktivierung aus diesem in den Ausgangszustand zurück versetzt werden kann.When In the present invention, an occupant protection agent becomes reversible understood that several times by an activation of an initial state put into an active state and by deactivating from this can be returned to the initial state.
Die Aktivierung der reversiblen Insassenschutzmittel schon vor dem eigentlichen Überschlagereignis führt in vorteilhafter Weise zu einer optimalen Insassenfixierung und -positionierung in einem Fahrzeugsitz. Anhand der reversiblen Ausführung der Insassenschutzmittel wird eine mehrfache Verwendung der Insassenschutzmittel ermöglicht.The Activation of reversible occupant protection even before the actual rollover event leads advantageously to an optimal occupant fixation and positioning in a vehicle seat. On the basis of the reversible Execution of occupant protection means becomes a multiple Use of occupant protection allowed.
Zusätzlich kann die mittels der Erfassungseinrichtung bestimmte Wahrscheinlichkeit des Überschlagereignisses mit von Sensoren, z. B. ein elektronisches Stabilitätsprogramm und/oder Federwegssensoren, ermittelten Daten auf ihre Plausibilität überprüft werden. Hierdurch wird eine unnötige Aktivierung der reversiblen Insassenschutzmittel vermieden.additionally may determine the probability determined by the detection means the rollover event with sensors, z. B. an electronic Stability program and / or spring travel sensors determined Data checked for plausibility become. This will cause an unnecessary activation of the reversible Occupant protection avoided.
Falls ein Überschlagereignis des Fahrzeugs erfolgt, werden zusätzlich irreversible, insbesondere pyrotechnische Insassenschutzmittel mittels der Steuereinheit aktiviert. Anhand der optimalen Insassenfixierung und -positionierung durch die reversiblen Insassenschutzmittel wird eine bestmögliche Wirkung der irreversiblen Insassenschutzmittel, z. B. Airbag, pyrotechnischer Gurtstraffer, erzielt. Weiterhin wird anhand der zusätzlichen Aktivierung der irreversiblen Insassenschutzmittel ein optimaler Schutz der Insassen des Fahrzeugs erreicht.If a rollover event of the vehicle takes place, in addition irreversible, in particular pyrotechnic occupant protection means the control unit activated. Based on the optimal occupant fixation and positioning by the reversible occupant protection means the best possible effect of irreversible occupant protection z. B. airbag, pyrotechnic belt tensioner scored. Continue based on the additional activation of irreversible occupant protection optimum protection of the occupants of the vehicle achieved.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.embodiments The invention will be described below with reference to a drawing explained.

So ist beispielsweise ein Sicherheitsgurtband vor einem Überschlagereignis anhand des reversiblen Sicherheitsgurtstraffers reversibel vorgespannt, so dass eine Straffenergie eines pyrotechnischen Gurtstraffers effektiv eingesetzt werden kann. Auch die Position der Insassen ist derart optimiert, dass eine maximale und bestmögliche Rückhaltung des/der Insassen mittels eines oder mehrerer Airbags erzielt wird.So For example, is a seat belt webbing before a rollover event Reversibly pretensioned by means of the reversible seatbelt tightener. so that a firming energy of a pyrotechnic belt tensioner effectively can be used. The position of the occupants is like that optimizes that maximum and best possible retention of the Inmates is achieved by means of one or more airbags.
