Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrzeuges mit einem Fahrerassistenzsystem, wobei das Fahrzeug bei Erfassen einer bevorstehenden Kollision automatisch abgebremst wird.The invention relates to a method for operating a vehicle with a driver assistance system, wherein the vehicle is automatically braked upon detection of an imminent collision.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zum Betrieb eines Fahrzeuges mit einem Fahrerassistenzsystem anzugeben.The invention has for its object to provide a comparison with the prior art improved method for operating a vehicle with a driver assistance system.
Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Verfahren zum Betrieb eines Fahrzeuges mit einem Fahrerassistenzsystem sieht vor, dass das Fahrzeug bei Erfassen einer bevorstehenden Kollision automatisch abgebremst wird. Erfindungsgemäß wird eine Bremskraft des während mittels des Fahrerassistenzsystems automatisch durchgeführten Bremsvorganges in einer vorgegebenen Zeitdauer vor Eintritt der Kollision automatisch verringert.A method for operating a vehicle with a driver assistance system provides that the vehicle is automatically braked upon detection of an impending collision. According to the invention, a braking force of the braking process automatically carried out by means of the driver assistance system is automatically reduced within a predetermined period of time before the collision occurs.
Wird die Bremskraft bei Durchführung des automatischen Bremsvorganges vor dem Eintritt der Kollision automatisch verringert, werden wirkende Kollisionskräfte an dem Fahrzeug besser aufgenommen, da das Fahrzeug aufgrund des Bremsvorganges keine Nickbewegung ausführt und dadurch ein Deformationsbereich des Fahrzeuges in Bezug auf ein Kollisionsobjekt, insbesondere ein Fahrzeug, optimiert ausgerichtet sein kann.If the braking force is automatically reduced when the automatic braking operation is carried out before the collision occurs, acting collision forces on the vehicle are better absorbed, since the vehicle does not pitch due to the braking process and thereby a deformation area of the vehicle with respect to a collision object, in particular a vehicle, Optimally aligned.
Bevorzugt wird der Bremsvorgang automatisch beendet, so dass die Fahrzeuginsassen aufgrund des Nichtmehrverzögerns des Fahrzeuges relativ zu im Fahrzeuginnenraum angeordneten Rückhaltemitteln verbessert positioniert sind, wobei aufgrund des Beendens des Bremsvorganges durch eine Bewegung der Fahrzeuginsassen in Richtung einer Sitzlehne eine Gurtlose des jeweiligen Sicherheitsgurtes verringert wird.Preferably, the braking operation is automatically terminated, so that the vehicle occupants are positioned improved due to the Nichtverzögererns of the vehicle relative to the vehicle interior retaining means, wherein due to the termination of the braking operation by a movement of the vehicle occupants in the direction of a seat back belt slack of the respective seat belt is reduced.
