Abstract
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrerassistenzsystems zur Ermittlung einer Aufmerksamkeit eines Fahrers (2) eines Fahrzeuges (1), wobei Lenkmuster des Fahrers (2) und Bedienhandlungen erfasst werden. Erfindungsgemäß wird zusätzlich zumindest eine Blickrichtung des Fahrers (2) ermittelt und in Abhängigkeit der Blickrichtung erfolgt eine Differenzierung in Bezug auf erfasste Lenkmuster.The invention relates to a method for operating a driver assistance system for determining an attention of a driver (2) of a vehicle (1), steering pattern of the driver (2) and operator actions being detected. According to the invention, at least one line of sight of the driver (2) is additionally determined and, depending on the viewing direction, a differentiation with respect to detected steering patterns takes place.
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Fahrerassistenzsystems zur Ermittlung einer Aufmerksamkeit eines Fahrers eines Fahrzeuges, wobei Lenkmuster des Fahrers und Bedienhandlungen erfasst werden.The invention relates to a method for operating a driver assistance system for determining a driver's attention of a vehicle, wherein driver's steering patterns and operator actions are detected.
Im Allgemeinen sind ein Fahrerassistenzsystem zur Ermittlung einer Aufmerksamkeit eines Fahrers eines Fahrzeuges, ein sogenannter Aufmerksamkeits-Assistent, und ein Verfahren zum Betrieb eines solchen Fahrerassistenzsystems bekannt. Mittels eines solchen Fahrerassistenzsystems wird das Risiko eines Sekundenschlafes bei einem schläfrigen Fahrer zumindest verringert. Die Aufmerksamkeit des Fahrers wird anhand einer Häufigkeit bestimmter Lenkmuster ermittelt. Zur Plausibilisierung einer anhand der erfassten Lenkmuster ermittelten Aufmerksamkeit werden Bedienhandlungen im Fahrzeug, beispielsweise das Drücken von Tasten eines Multifunktionslenkrades und/oder eines Infotainmentsystems des Fahrzeuges, erfasst.In general, a driver assistance system for detecting a driver's attention of a vehicle, a so-called Attention Assistant, and a method for operating such a driver assistance system are known. By means of such a driver assistance system, the risk of microsleep in a drowsy driver is at least reduced. The attention of the driver is determined by a frequency of certain steering patterns. To check the plausibility of a detected by the detected steering pattern attention operations in the vehicle, such as pressing keys of a multifunction steering wheel and / or an infotainment system of the vehicle detected.
Der Erfindung liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zum Betrieb eines Fahrerassistenzsystems zur Ermittlung einer Aufmerksamkeit eines Fahrers eines Fahrzeuges anzugeben.The invention has for its object to provide a comparison with the prior art improved method for operating a driver assistance system for determining an attention of a driver of a vehicle.
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 Fahrerassistenzsystems zur Ermittlung einer Aufmerksamkeit eines Fahrers eines Fahrzeuges sieht vor, dass Lenkmuster des Fahrers und Bedienhandlungen erfasst werden. Erfindungsgemäß wird zusätzlich zumindest eine Blickrichtung des Fahrers ermittelt und in Abhängigkeit der ermittelten Blickrichtung erfolgt eine Differenzierung in Bezug auf erfasste Lenkmuster.A method for operating a driver assistance system for determining a driver's attention of a vehicle provides that driver's steering patterns and operator actions are detected. According to the invention, at least one line of sight of the driver is additionally determined, and depending on the determined line of vision, a differentiation with respect to detected steering patterns takes place.
Mittels des Verfahrens erfolgt insbesondere eine Differenzierung dahingehend, dass zwischen Lenkmustern, die aus Unachtsamkeit und Lenkmustern, die aus Müdigkeit resultieren, unterschieden wird.In particular, differentiation is made by means of the method in that a distinction is made between steering patterns which result from carelessness and steering patterns resulting from tiredness.
Dadurch wird eine Differenzierung in einer Gewichtung der Lenkmuster zur Verbesserung des Fahrerassistenzsystems ermöglicht, wodurch eine Ausgabe falscher Warnhinweise oder aber das Fehlen einer Warnhinweisausgabe zumindest verringert werden kann.Thereby, a differentiation in a weighting of the steering pattern is made possible for the improvement of the driver assistance system, whereby an output of false warnings or the lack of a warning message output can at least be reduced.
Zudem ist es möglich einen entsprechenden Warnhinweis bei ermittelter Unachtsamkeit und einen entsprechenden weiteren Warnhinweis bei ermittelter Müdigkeit an den Fahrer des Fahrzeuges auszugeben.In addition, it is possible to issue a corresponding warning in the case of carelessness detected and a corresponding further warning in the event of a detected fatigue to the driver of the vehicle.
