Description
Die Erfindung betrifft ein Fahrassistenzsystem zum Unterstützen eines Fahrers eines Fahrzeugs, mit einem Müdigkeitserkennungssystem zum Erkennen einer Ermüdung des Fahrers.The The invention relates to a driving assistance system for assisting a driver of a vehicle with a fatigue detection system to detect driver fatigue.
Fahrassistenzsysteme
zum Unterstützen eines Fahrers eines Fahrzeuges sind bekannt.
Diese können ein Müdigkeitserkennungssystem aufweisen, mittels
dem erkannt werden kann, ob der Fahrer ermüdet ist. Die
Aufgabe der Erfindung ist es, ein verbessertes Fahrassistenzsystem zum Unterstützen eines Fahrers eines Fahrzeuges für eine Ermüdung des Fahrers bereitzustellen, insbesondere eine Fahrsicherheit zu erhöhen.task The invention is to provide an improved driver assistance system for assistance a driver of a vehicle for a fatigue to provide the driver, in particular a driving safety increase.
Die Aufgabe ist bei einem Fahrassistenzsystem zum Unterstützen eines Fahrers eines Fahrzeuges, mit einem Müdigkeitserkennungssystem zum Erkennen einer Ermüdung des Fahrers dadurch gelöst, dass bei einer mittels des Müdigkeitserkennungssystems erkannten Ermüdung des Fahrers ein Warnblinklicht des Fahrers zum Warnen weiterer Verkehrsteilnehmer aktiviert wird. Vorteilhaft können die weiteren Verkehrsteilnehmer auf die Gefahr des ermüdeten Fahrers hingewiesen werden, wobei sich vorteilhaft eine Fahrsicherheit sowohl des Fahrzeugs als auch der anderen Verkehrsteilnehmer erhöht, da diese gewarnt sind und gegebenenfalls einen drohenden Unfall vermeiden können.The Task is with a driver assistance system to support a driver of a vehicle, with a fatigue detection system solved by recognizing fatigue of the driver, that when detected by the fatigue detection system Driver's fatigue a driver's hazard flashlight Warning other road users is activated. Can be advantageous the other road users at the risk of tired Be advised driver, which is advantageous driving safety both the vehicle and the other road users, because they are warned and possibly an imminent accident can avoid.
Ein Ausführungsbeispiel des Fahrassistenzsystems zeichnet sich dadurch aus, dass das Müdigkeitserkennungssystem zumindest ein Element der folgenden Gruppe aufweist oder mit diesem im Datenaustausch steht: Ein Spurverlasserkennungssystem, eine Pulsüberwachung des Fahrers, ein optisches Überwachungssystem zum Überwachen des Fahrers, insbesondere mit einer Lidspaltüberwachung und ein Querführungsassistenzsystem. Vorteilhaft kann auf verschiedene Art und Weise die Ermüdung des Fahrers festgestellt werden. Es ist beispielsweise denkbar, auf eine Ermüdung des Fahrers zu schließen, wenn dieser eine durchgezogene Linie überfährt oder eine nicht durchgezogene Spurmarkierung über einen längeren Zeitraum nur teilweise überfährt und/oder dabei nicht blinkt. Ferner kann mittels einer Auswertung einer Pulsfrequenz des Fahrers auf eine Ermüdung geschlossen werden. Mittels des optischen Überwachungssystems ist es möglich, beispielsweise ein Gesicht des Fahrers zu überwachen, insbesondere einen Lidspalt des Fahrers zu vermessen und/oder zu erkennen, um aus diesem Maß auf die Ermüdung des Fahrers zu schließen. Es ist vorteilhaft möglich, mittels eines ohnehin vorhandenen Querführungsassistenzsystems die Daten für das Müdigkeitserkennungssystem bereitzustellen, beispielsweise über einen in dem Fahrzeug ohnehin vorgesehen Bus, beispielsweise einen CAN-Bus.One Embodiment of the driver assistance system is characterized characterized in that the fatigue detection system at least has an element of the following group or with this in the data exchange stands: a lane departure warning system, a heart rate monitor the driver, an optical monitoring system for monitoring of the driver, in particular with a eyelid gap monitoring and a lateral guidance assistance system. Can be beneficial different way the driver's fatigue determined become. It is conceivable, for example, to fatigue Close the driver if this is a solid Line overrun or a non-solid line Lane marking for a longer period only partially overrun and / or not blinking. Furthermore, by means of an evaluation of a pulse frequency of the driver be closed on a fatigue. By means of the optical monitoring system it is possible, for example, a face of the driver to monitor, in particular an eyelid of the driver to gauge and / or to recognize to this extent to close the driver's fatigue. It is advantageous possible, by means of an already existing Querführungsassistenzsystems the data for the To provide fatigue detection system, for example via a bus provided in the vehicle anyway, for example a CAN bus.
Ein weiteres Ausführungsbeispiel des Fahrassistenzsystems zeichnet sich dadurch aus, dass ein Grad der Ermüdung erkennbar ist und in Abhängigkeit von diesem Grad und einem oder mehreren Schwellwerten zumindest eine der folgenden Aktionen durchführbar ist: Ausgeben einer situationsangepassten Müdigkeitswarnung, Eingreifen in eine Fahrdynamik des Fahrzeugs, Abbremsen des Fahrzeugs, Steuern des Fahrzeugs an einen Fahrbahnrand oder einen Standstreifen.One Another embodiment of the driver assistance system draws characterized by a degree of fatigue recognizable is and depending on this degree and one or several thresholds at least one of the following actions feasible is: issuing a situation-adapted fatigue warning, Intervention in a driving dynamics of the vehicle, braking of the vehicle, taxes of the vehicle to a lane edge or a hard shoulder.
Vorteilhaft kann auf die erkannte Ermüdung so reagiert werden, dass die Gefahr, die von dieser Ermüdung ausgeht eliminiert oder zumindest deutlich reduziert werden kann, beispielsweise durch ein gezieltes Warnen des Fahrers, wobei dieser dabei wieder aufwacht. Eine solche Warnung kann beispielsweise haptische Reize, beispielsweise ein Vibrieren eines Sitzes und/oder eines Lenkrades des Fahrzeuges umfassen, wobei vorteilhaft solche Reize auch bei starker Ermüdung noch vergleichsweise gut wahrgenommen werden. Denkbar sind auch akustische und/oder optische Warnungen, beispielsweise Blinklichter oder Warntöne. Außerdem kann durch gezielte Eingriffe in die Fahrdynamik des Fahrzeugs, zusätzlich die Gefahr reduziert werden, insbesondere vorteilhaft dann, falls trotz der Warnungen der Fahrer nicht aufwacht und entsprechend reagiert. In solch einem Fall kann vorteilhaft darauf geschlossen werden, dass akustische und/oder optische und/oder haptische Warnungen nicht zum Ziel geführt haben, da der Fahrer sehr tief schläft und/oder gegebenenfalls ernstlich verletzt ist, beispielsweise sein Bewusstsein verloren hat. Für diesen Fall, also wenn ein besonders hoher Grad der Ermüdung beziehungsweise Nichttätigkeit des Fahrers festgestellt wird, kann vorteilhaft auch ohne jegliches Zutun des Fahrers das Fahrzeug in Sicherheit gebracht werden, beispielsweise durch das Abbremsen und/oder das Steuern auf den Fahrbahnrand oder den Seitenstreifen.Advantageously, the perceived fatigue can be reacted so that the danger emanating from this fatigue can be eliminated or at least significantly reduced, for example by intentional warning of the driver, who wakes up again. Such a warning may include, for example, haptic stimuli, for example a vibration of a seat and / or a steering wheel of the vehicle, with such stimuli advantageously still being perceived comparatively well even under severe fatigue. Also conceivable are acoustic and / or visual warnings, such as flashing lights or warning tones. In addition, by targeted intervention in the driving dynamics of the vehicle, in addition, the risk can be reduced, particularly advantageous if, despite the warnings, the driver does not wake up and reacts accordingly. In such a case, it can advantageously be concluded that acoustic and / or visual and / or haptic warnings have not led to the goal, since the driver sleeps very deeply and / or is seriously injured, for example, has lost his consciousness. For this case, so if a particularly high degree of fatigue or non-activity of the driver is determined, can advantageously also without any action of the Fah rers the vehicle are brought to safety, for example by braking and / or driving on the edge of the road or the side strip.
Die Aufgabe ist außerdem bei einem Fahrzeug mit einem vorab beschriebenen Fahrassistenzsystem gelöst. Es ergeben sich die vorab beschriebenen Vorteile.The Task is also in a vehicle with a pre solved driver assistance system described. It turns out the advantages described above.
