Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren und eine Vorrichtung zur Ansteuerung einer reversiblen Insassenschutzvorrichtung eines Fahrzeuges anzugeben.The invention is based on the object of specifying a method and a device for controlling a reversible occupant protection device of a vehicle which are improved compared to the prior art.
Die Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die in Anspruch 1 und hinsichtlich der Vorrichtung durch die in Anspruch 3 angegebenen Merkmale gelöst.The object is achieved according to the invention with regard to the method by the features specified in
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous further developments of the invention are the subject of the subclaims.
Bei einem Verfahren zur Ansteuerung mindestens einer reversiblen Insassenschutzvorrichtung eines Fahrzeuges ist die mindestens eine reversible Insassenschutzvorrichtung ein reversibler Gurtstraffer und wird in Abhängigkeit erfasster Fahrzustandsgrößen angesteuert und in eine Wirkstellung positioniert. Dabei wird der mindestens eine reversible Gurtstraffer in Abhängigkeit einer momentanen Fahrgeschwindigkeit des Fahrzeuges angesteuert und in die Wirkstellung positioniert, wobei der mindestens eine reversible Gurtstraffer in Abhängigkeit der momentanen Fahrgeschwindigkeit des Fahrzeuges mit unterschiedlicher Auslösecharakteristik ausgelöst.In a method for controlling at least one reversible occupant protection device of a vehicle, the at least one reversible occupant protection device is a reversible belt tensioner and is detected as a function Driving state variables controlled and positioned in an active position. The at least one reversible seat belt tensioner is activated as a function of a current driving speed of the vehicle and positioned in the operative position, the at least one reversible seat belt tensioner being triggered depending on the current driving speed of the vehicle with different trigger characteristics.
Erfindungsgemäß wird als Fahrzustandsgröße eine Lenkbewegung erfasst und mit steigender momentaner Fahrgeschwindigkeit des Fahrzeuges, bei der eine Lenkbewegung durchgeführt wird, wird eine steigende Straffkraft des reversiblen Gurtstraffers eingestellt.According to the invention, a steering movement is recorded as the driving state variable, and as the current driving speed of the vehicle at which a steering movement is carried out increases, an increasing tensioning force of the reversible belt tensioner is set.
Dabei wird der reversible Gurtstraffer entsprechend der momentanen Fahrgeschwindigkeit gestrafft.The reversible belt tensioner is tightened according to the current driving speed.
Anhand des erfindungsgemäßen Verfahrens wird die reversible Insassenschutzvorrichtung auch bei einer momentanen geringen Fahrgeschwindigkeit angesteuert, wobei eine Auslösecharakteristik, beispielsweise eine Spannkraft des reversiblen Gurtstraffers, aus der momentanen Fahrgeschwindigkeit resultiert. Dadurch kann in vorteilhafter Weise auch bei einer vergleichsweise sportlichen Fahrweise ein Fahrkomfort für Fahrzeuginsassen erhöht werden.Using the method according to the invention, the reversible occupant protection device is also activated at a momentary low driving speed, with a trigger characteristic, for example a tensioning force of the reversible belt tensioner, resulting from the momentary driving speed. As a result, driving comfort for vehicle occupants can be increased in an advantageous manner even with a comparatively sporty driving style.

Als Fahrzustandsgrößen wird das mindestens eine erste Signal
Darüber hinaus werden von der Fahrzustandssensorik
Die von der Fahrzustandssensorik
Aus dem Stand der Technik ist bekannt, dass die reversible Insassenschutzvorrichtung
Um einen Schutz der Fahrzeuginsassen in unfallkritischen Fahrsituationen bei vergleichsweise schnellen Lenkbewegungen des Fahrzeugführers sicherzustellen, ist vorgesehen, dass die reversible Insassenschutzvorrichtung
Hierzu sind für die Fahrgeschwindigkeit als zweites Signal
Fährt das Fahrzeug
Hierzu wird beispielsweise ein auf eine Wickelrolle des Gurtstraffers wirkender Elektromotor, welcher eine Aufroll- und eine Straff-Funktion erfüllt, entsprechend angesteuert. Dabei ist eine Drehzahl des Elektromotors in Abhängigkeit der momentanen Fahrgeschwindigkeit ansteuerbar.For this purpose, for example, an electric motor acting on a winding roller of the belt tensioner, which fulfills a roll-up and a tensioning function, is controlled accordingly. A speed of the electric motor can be controlled as a function of the current driving speed.
Der reversible Gurtstraffer als reversible Insassenschutzvorrichtung
Dadurch ist besonders bevorzugt ein vorbeugender Insassenschutz auch bei geringer momentaner Fahrgeschwindigkeit sichergestellt.As a result, preventive occupant protection is particularly preferably ensured even when the current driving speed is low.
Ferner erhöht sich anhand des Verfahrens ein Fahrkomfort der Fahrzeuginsassen beispielsweise bei einer sportlichen Fahrweise des Fahrzeugführers.Furthermore, the method increases the driving comfort of the vehicle occupants, for example when the vehicle driver drives in a sporty manner.
