Bei einem Verfahren zur Ermittlung von Müdigkeit und/oder Unachtsamkeit eines Fahrers eines Fahrzeugs wird die Müdigkeit und/oder Unachtsamkeit zumindest mittels eines erfassten Lenkverhaltens Fahrers ermittelt. Erfindungsgemäß wird bei erfasster Müdigkeit und/oder Unachtsamkeit ein Konditionszustand des Fahrers ermittelt, wobei in Abhängigkeit des ermittelten Konditionszustandes wenigstens eine Handlungsanweisung an den Fahrer ausgegeben wird.In a method for determining fatigue and / or carelessness of a driver of a vehicle, the fatigue and / or carelessness is determined at least by means of a detected steering behavior of the driver. According to the invention, a condition condition of the driver is determined with detected fatigue and / or carelessness, wherein at least one instruction is issued to the driver depending on the determined condition condition.
Bevorzugt wird der Konditionszustand mittels erfasster Symptome, welche auf einen Zustand des Fahrers hinweisen, ermittelt. Dabei werden als Symptome kognitive, emotionale und/oder somatische Symptome erfasst.Preferably, the condition condition is determined by means of detected symptoms which indicate a condition of the driver. Cognitive, emotional and / or somatic symptoms are recorded as symptoms.
Das Verfahren sieht vor, dass in Abhängigkeit des mittels der erfassten Symptome ermittelten Konditionszustandes in vorteilhafter Weise Handlungsanweisungen in Form von empfohlenen, durchzuführenden Maßnahmen an den Fahrer ausgegeben werden, um insbesondere die Aufmerksamkeit des Fahrers zu erhöhen.The method provides that, depending on the condition condition determined by means of the detected symptoms, instructions for action in the form of recommended measures to be taken are advantageously output to the driver, in particular to increase the driver's attention.
Werden somatische Symptome, wie z. B. Kraftlosigkeit und/oder Augenbrennen des Fahrers, erfasst, wird dem Fahrer als Handlungsanweisung ausgegeben, zumindest eine kurze Schlafpause einzulegen.Are somatic symptoms, such. B. powerlessness and / or eye burning of the driver detected, the driver is issued as an instruction to insert at least a short sleep break.
Mittels des Verfahrens kann in besonders vorteilhafter Weise die Sicherheit im Straßenverkehr erhöht werden, da der Konditionszustand des Fahrers ermittelt wird und entsprechend des ermittelten Konditionszustandes Handlungsanweisungen in Form von Empfehlungen an den Fahrer ausgegeben werden. By means of the method, road safety can be increased in a particularly advantageous manner, since the driver's condition condition is determined and, according to the determined condition condition, instructions for action in the form of recommendations are output to the driver.
Besonders bevorzugt werden die Handlungsanweisungen optisch, akustisch und/oder haptisch an den Fahrer ausgegeben.Particularly preferably, the instructions are issued visually, acoustically and / or haptically to the driver.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.

Zur optischen Ausgabe der Handlungsanweisungen H ist ein Anzeigebereich innerhalb einer Instrumententafel des Fahrzeugs als Ausgabeeinheit
Im Betrieb der Vorrichtung werden bzw. wird im Fahrbetrieb des Fahrzeugs
Hinsichtlich des Lenkverhaltens werden zumindest eine Lenkruhephase und eine sich an die Lenkruhephase anschließende Lenkaktion erfasst, wobei die erfassten Signale S der Steuereinheit
In der Steuereinheit
Gleichzeitig wird der Fahrer mittels der Bilderfassungseinheit
Mittels der Signale S hinsichtlich des erfassten Lenkwinkels und der aufgenommenen Bilddaten B wird ein Konditionszustand des Fahrers des Fahrzeugs
Um den Konditionszustand zu ermitteln, werden vorzugsweise mittels der Bilderfassungseinheit
Zu den kognitiven sowie emotionalen Symptomen zählen das Abschweifen der Gedanken, Langeweile, Durstigkeit, Gähnen, sich leicht ablenken lassen und/oder ärgerlich werden.Cognitive and emotional symptoms include the wandering of the mind, boredom, thirst, yawning, being easily distracted and / or annoying.
In einem Übergangsstadium zwischen den kognitiven sowie emotionalen Symptomen zu den somatischen Symptomen treten die kognitiven sowie emotionalen Symptome gekoppelt mit ersten Auswirkungen auf das Fahrverhalten des Fahrers auf. In a transitional stage between the cognitive and emotional symptoms of the somatic symptoms, the cognitive and emotional symptoms coupled with initial effects on the driver's driving behavior occur.
Dieses Übergangsstadion ist von Symptomen gekennzeichnet, welche sich dahingehend äußern, dass der Fahrer sich nicht konzentrieren kann, unruhig wird, leichte Fahrfehler macht, keine Lust mehr hat weiter zu fahren und/oder unbedingt eine Pause machen will.This transitional stadium is characterized by symptoms that suggest that the driver can not concentrate, becomes restless, makes light driving mistakes, does not feel like driving on and / or wants to take a break.
Somatische Symptome als weitere Einteilung zur Ermittlung des Konditionszustandes des Fahrers werden dadurch erkannt, dass der Fahrer sich kraftlos fühlt, Probleme hat seine Fahrspur zu halten, seine Augen brennen, er sich nicht mehr an die bereits gefahrene Strecke erinnern kann, seine Augenlider schwer sind und/oder er verschwommen sieht.Somatic symptoms as a further classification to determine the condition condition of the driver are recognized by the fact that the driver feels powerless, has problems keeping his lane, burning his eyes, he can no longer remember the already driven track, his eyelids are heavy and / or he looks blurry.
Mittels der Bilderfassungseinheit
Wird wenigstens ein Symptom erfasst, erfolgt innerhalb der Steuereinheit
Mittels der Unterscheidung der Systemgruppen wird auf den Konditionszustand des Fahrers geschlossen, wobei in Abhängigkeit des ermittelten Konditionszustandes die Handlungsanweisungen H in Form von Empfehlungen an den Fahrer ausgegeben werden.By means of the distinction of the system groups is concluded on the condition condition of the driver, wherein depending on the condition condition determined, the instructions H are issued in the form of recommendations to the driver.
Werden anhand des zumindest optisch erfassten Verhaltens des Fahrers kognitive sowie emotionale Symptome erkannt, wird zumindest eine Handlungsanweisung H, welche die kognitiven Funktionen des Fahrers von außen anregt, ausgegeben.If cognitive and emotional symptoms are detected on the basis of the driver's at least optically detected behavior, at least one instruction H, which stimulates the driver's cognitive functions from the outside, is output.
Beispielsweise wird als Handlungsanweisung die Empfehlung ausgegeben, Musik oder Nachrichten zu hören, Wortbeiträge zu hören, Frischluft zuzuführen, sofern es die momentane Verkehrslage zulässt, andere Verkehrsteilnehmer zu beobachten und/oder in der Gegend umherzuschauen.For example, a recommendation is given to listen to music or news, to hear words, to supply fresh air, as long as the current traffic situation allows it to observe other road users and / or to look around the area.
Im erkannten Übergangsstadium, wenn kognitive sowie emotionale Symptome gekoppelt mit ersten Fahrfehlern auftreten, wird zumindest eine Handlungsanweisung H ausgegeben, die den Fahrer dazu animiert, seine persönliche Aktivität durch vergleichsweise sanfte motorische Aktivierungen zu steigern. Als Handlungsanweisung H wird beispielsweise ausgegeben, Kaugummi zu kauen, Bonbons zu lutschen, Kaffee zu trinken, Gedächtnisaufgaben zu lösen, singen oder mitzusingen, Arme und/oder Beine zu strecken und/oder bevorzugt mittels einer Freisprecheinrichtung zu telefonieren.In the perceived transitional stage, when cognitive as well as emotional symptoms coupled with first driving errors occur, at least one action instruction H is issued which encourages the driver to increase his personal activity by comparatively gentle motor activations. As an instruction H, for example, issued chewing gum to suck candy, drink coffee, solve memory problems, singing or singing along, arms and / or legs to stretch and / or preferably using a hands-free phone.
Treten somatische Symptome auf, die anhand der Bilddaten B mittels der Steuereinheit
Weist der Fahrer somatische Symptome auf, befindet sich der Fahrer in einem Konditionszustand, welcher mittels eines Tätigkeitswechsels nicht geändert werden kann. D. h. der Fahrer befindet sich in einem Zustand, welcher durch einen Tätigkeitswechsel, wie bei den anderen beiden Symptomgruppen, nicht änderbar ist.If the driver has somatic symptoms, the driver is in a condition which can not be changed by means of a change of activity. Ie. The driver is in a state which can not be changed by a change of activity, as with the other two symptom groups.
In der Symptomgruppe der kognitiven sowie emotionalen Symptome befindet sich der Fahrer in einem vigilanzgeminderten Zustand. In diesem Zustand sind bzw. ist die Daueraufmerksamkeit und/oder die Wachheit des Fahrers gemindert.In the symptom group of cognitive and emotional symptoms, the driver is in a vigilance-reduced state. In this condition, the driver's perpetual attention and / or alertness is diminished.
Durch eine Umsetzung der Handlungsanweisung H, welche einen Tätigkeitswechsel empfiehlt, wird dem Fahrer Abwechslung geboten, wodurch die Aktivität sowie die Aufmerksamkeit des Fahrers gesteigert werden können.By implementing the instruction H, which recommends a change of activity, the driver is offered variety, whereby the activity and the attention of the driver can be increased.
In der Symptomgruppe des Übergangsstadiums, das durch kognitive sowie emotionale Symptome und bereits teilweise auftretende Fahrfehler gekennzeichnet ist, umfassen die Handlungsanweisungen H Empfehlungen, die von relativ leichter motorischer Art sind, da vergleichsweise mehr Aktivierung erforderlich ist, um den Fahrer zur Steigerung seiner Aufmerksamkeit Abwechslung zu bieten.In the transient stage symptom group, which is characterized by cognitive and emotional symptoms and already partially occurring driving errors, the handling instructions H include recommendations that are of relatively light motor type, since comparatively more activation is required to give the driver variety for increasing his or her attention Offer.
Bei der Symptomgruppe der somatischen Symptome befindet sich der Fahrer des Fahrzeugs
Die Handlungsanweisungen H werden bevorzugt in einem Anzeigebereich der Instrumententafel als Ausgabeeinheit
Zusätzlich oder alternativ fungieren die Lautsprecher des Fahrzeugs
Das Verfahren und die Vorrichtung ermöglichen eine Symptomerkennung, wobei die Symptome in Symptomgruppen eingeteilt sind. Mittels der Symptome sowie der Einteilung in Symptomgruppen kann ein Konditionszustand des Fahrers ermittelt werden. Diese Erkenntnis ermöglicht es, dem Fahrer eine dem Konditionszustand entsprechende Handlungsanweisung H als Empfehlung nahezulegen.The method and apparatus enable symptom recognition, with symptoms grouped into symptom groups. By means of the symptoms as well as the classification into symptom groups a state of condition of the driver can be determined. This knowledge makes it possible to suggest to the driver an instruction H corresponding to the condition condition as a recommendation.
Mittels des Verfahrens und der Vorrichtung kann die Sicherheit von Verkehrsteilnehmern im Straßenverkehr erhöht werden.By means of the method and the device, the safety of road users can be increased.
