Title
(DE) VERFAHREN ZUM BETREIBEN EINES FAHRERASSISTENZSYSTEMS UND FAHRERASSISTENZSYSTEM
(EN) METHOD FOR OPERATING A DRIVER ASSISTANCE SYSTEM, AND DRIVER ASSISTANCE SYSTEM
(FR) PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER UN DISPOSITIF D'AIDE À LA CONDUITE, AINSI QUE DISPOSITIF D'AIDE À LA CONDUITE
Abstract
(DE) Die Erfindung betrifft ein Verfahren zum Betreiben eines Fahrerassistenzsystems (5), mittels dessen eine einem mit dem Fahrerassistenzsystem (5) ausgestatteten Kraftfahrzeug (3) drohende Kollision mit einem möglichen Kollisionsobjekt (1) erfasst wird und basierend darauf in dem Kraftfahrzeug (3) mittels des Fahrerassistenzsystems (5) ein Assistenzsignal bereitgestellt wird, wobei ein Sichtfeld (2) eines Fahrers des Kraftfahrzeugs (3) mittels einer Sensorik (7) erfasst wird, sodass anhand des Sichtfelds (2) eine voraussichtliche Reaktionszeit des Fahrers bestimmt wird. Die Erfindung sieht vor, dass eine Vielzahl von möglichen Kollisionsobjekten (1) erfasst wird und eines davon als ein primäres Kollisionsobjekt (8) eingestuft wird und ein Bereitstellungszeitpunkt, zu welchem das Assistenzsignal bereitgestellt wird, basierend auf der voraussichtlichen Reaktionszeit und auf einer voraussichtlichen Zeitspanne bis zur Kollision mit dem primären Kollisionsobjekt (8) eingestellt wird.
(EN) The invention relates to a method for operating a driver assistance system (5), by means of which an imminent collision of a motor vehicle (3) equipped with the driver assistance system (5) with a possible collision object (1) is detected and on the basis thereof an assistant signal is provided in the motor vehicle (3) by means of the driver assistance system (5), wherein the field of view (2) of a driver of the motor vehicle (3) is detected by a sensor system (7) so that an expected reaction time of the driver is determined using the field of view (2). According to the invention, a plurality of possible collision objects (1) are detected, one of the collision objects is classified as a primary collision object (8), and a signal providing time at which the assistance signal is provided is set on the basis of the expected reaction time and on the basis of an expected duration until the collision with the primary collision object (8).
(FR) L'invention se rapporte à un procédé permettant de faire fonctionner un système d'aide à la conduite (5), au moyen duquel une collision imminente d'un véhicule à moteur (3) équipé du système d'aide à la conduite (5) avec un éventuel objet de collision (1) est détectée et, sur la base de ceci, un signal d'aide est émis dans le véhicule à moteur (3) au moyen du système d'aide à la conduite (5), le champ de vision (2) d'un conducteur du véhicule à moteur (3) étant détecté par un système de détection (7) de telle sorte qu'un temps de réaction attendu du conducteur soit déterminé à l'aide du champ de vision (2). Selon l'invention, une pluralité d'éventuels objets de collision (1) sont détectés, l'un des objets de collision est classé comme étant un objet de collision primaire (8), et un moment de fourniture de signal où le signal d'aide est émis, est défini sur la base du temps de réaction attendu et sur la base d'une durée attendue jusqu'à la collision avec l'objet de collision primaire (8).
