Abstract
Description
Die
Erfindung geht aus von einem Verfahren und einer Vorrichtung zur
Fahrerzustandserkennung nach der Gattung des Hauptanspruchs. Aus
der
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Verfahren mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass die Genauigkeit der Fahrerzustandserkennung wesentlich verbessert wird. The inventive method with the features of the main claim has the opposite Advantage that the accuracy of the driver condition detection essential is improved.
Hierbei wird der Effekt genutzt, dass die Körpertemperatur an besonders peripheren Stellen des Körpers gut mit der tatsächlichen Schläfrigkeit des Fahrers korreliert. Während Temperaturmessungen an beliebigen Körperstellen oder auch beliebigen Stellen der Hand keine sichere Aussage zulassen, ob der Fahrer wach ist, hat sich gezeigt, dass insbesondere Messungen an den vordersten Fingergliedern, also an den Fingergliedern, die die Fingerspitze beinhalten, insbesondere am kleinen Finger, einen sehr guten Rückschluss auf die tatsächliche Schläfrigkeit des Fahrers geben. Gleiches gilt auch für die vordersten Zehglieder.in this connection the effect is used that the body temperature at particularly peripheral parts of the body good with the actual drowsiness correlated by the driver. While Temperature measurements at arbitrary body parts or anywhere the hand can not say for sure whether the driver is awake, It has been shown that especially measurements at the foremost Phalanges, ie on the phalanges, the fingertip Include, especially on the little finger, a very good inference on the actual Drowsiness of Give driver. The same applies to the foremost toe links.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Verfahrens und der im nebengeordneten Anspruch angegebenen Vorrichtung möglich. Besonders vorteilhaft ist es, zur Körpertemperaturmessung einen Ring vorzusehen, der von einem Fahrer an einem Finger oder einem Zeh getragen wird und diesen kontaktiert. Insbesondere ist ein Anbringen des Rings an dem kleinen Finger oder an dem kleinen Zeh vorteilhaft, da hier die besten Messergebnisse zu erwarten sind.By in the subclaims listed activities are advantageous developments and improvements of the main claim specified method and specified in the independent claim Device possible. It is particularly advantageous for body temperature measurement Ring provided by a driver on a finger or a Toe is worn and contacted. In particular, an attachment of the ring on the little finger or on the little toe, because the best results can be expected here.
Bevorzugt ist der Ring mit einem Temperatursensor ausgestattet, der bevorzugt das Messergebnis drahtlos an einen Empfänger im Fahrzeug zur weiteren Auswertung überträgt. Hierdurch ist eine besonders komfortable Erfassung der Schläfrigkeit des Fahrers möglich, da auf Leitungen für eine Datenübertragung verzichtet werden kann.Prefers the ring is equipped with a temperature sensor, which is preferred the measurement result wirelessly to a receiver in the vehicle for further Evaluation transfers. hereby is a particularly comfortable recording of the drowsiness of the Driver possible, there on lines for a data transfer can be waived.
Bevorzugt wird die auf diese Weise gewonnene Erkenntnis über die mögliche Schläfrigkeit des Fahrers mit Bewertungen anderer Fahrzeugsystemen kombiniert, so dass über die Schläfrigkeit des Fahrers mit hoher Sicherheit einer Aussage getroffen werden kann.Prefers is the knowledge gained in this way about the possible drowsiness of the driver with ratings other vehicle systems combined, so that over drowsiness of the driver with high certainty of a statement can.
Bevorzugt ist eine erfindungsgemäße Vorrichtung zur Erfassung der Schläfrigkeit des Fahrers mit einer Warneinheit verbunden, über die an den Fahrer eine Warnung dann ausgegeben wird, wenn er von der Auswerteeinheit als schläfrig eingestuft wird.Prefers is a device according to the invention to detect drowsiness the driver is connected to a warning unit, via which to the driver a Warning is issued when it is received by the evaluation unit as sleepy is classified.
Die Erhöhung der Fingertemperatur, wenn der Fahrer ermüdet, ist bedingt durch eine Vasodilatation oberflächennaher Gefäße. Weitere Versuche haben gezeigt, dass eine provozierte Vasokonstriktion dieser Gefäße, wie sie z.B. durch eine Kühlung der Extremitäten erreicht werden kann, die Schläfrigkeit des Fahrers beeinflussen kann. Vorteilhaft werden somit die Temperaturverhältnisse im Fahrzeuginneren derart geregelt, dass eine Schläfrigkeit des Fahrers unterdrückt oder zumindest vermindert werden kann.The increase the finger temperature when the driver tires is due to a Vasodilation near the surface Vessels. Further Experiments have shown that a provoked vasoconstriction of this Vessels, like they e.g. by cooling the extremities can be achieved, the drowsiness of the driver. Thus, the temperature conditions become advantageous in the vehicle interior so regulated that a drowsiness of the driver suppressed or at least can be reduced.
In einer weiteren bevorzugten Ausgestaltung der Erfindung können daher für den Fall, dass eine Erhöhung der Temperatur an den äußeren Extremitäten festgestellt wird, Kühlmittel aktiviert werden, die die Gliedmaßen kühlen, also die Arme und/oder die Beine. Insbesondere ist es hierbei vorteilhaft, z.B. eine Klimaanlage zu aktivieren und kühlere Luft in den Fußraum des Fahrzeugs einzuleiten. In einer weiteren Ausgestaltung kann auch das Lenkrad gekühlt werden. Die Abkühlung der Gliedmaßen, also z.B. der Fingerspitzen, hat einen unmittelbaren Einfluss auf die Schläfrigkeit des Fahrers, so dass durch eine entsprechende Kühlung der Ermüdung des Fahrers zumindest kurzfristig entgegengewirkt werden kann.In Another preferred embodiment of the invention can therefore for the Case, that an increase the temperature on the outer extremities is, coolant activated, which cool the limbs, so the arms and / or the legs. In particular, it is advantageous here, e.g. an air conditioner to activate and cooler Air in the footwell of the vehicle. In a further embodiment can also the steering wheel cooled become. The cooling the limbs, ie e.g. the fingertips, has an immediate impact drowsiness of the driver, so that by appropriate cooling the fatigue of the Driver can be counteracted, at least in the short term.
