Aufgabe der Erfindung ist es, eine Vorrichtung zum Überwachen des Zustands eines Fahrers anzugeben, welche einfach und kostengünstig aufgebaut ist.task The invention is an apparatus for monitoring the condition of a To indicate driver, which is simple and inexpensive.
Die Erfindung löst diese Aufgabe durch Bereitstellung einer Vorrichtung zum Überwachen des Zustands eines Fahrers mit den Merkmalen des Patentanspruchs 1.The Invention solves this object by providing a device for monitoring the condition of a driver having the features of the claim 1.
Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.advantageous embodiments and further developments of the invention are specified in the dependent claims.
Erfindungsgemäß umfasst eine Sensoreinrichtung mindestens ein im Sicherheitsgurt integriertes zugempfindliches Element, welches ein eine Weitung des Brustkorbs repräsentierendes Dehnungssignal erzeugt, wobei die Sensoreinrichtung das erzeugte Dehnungssignal an eine Auswerte- und Steuereinheit überträgt, welche das Dehnungssignal zur Bestimmung der Atemfrequenz des Fahrers auswertet. Die zugempfindlichen Elemente sind in vorteilhafter Weise einfach aufgebaut und können beispielsweise als Dehnungsmessstreifen kostengünstig in den Sicherheitsgurt integriert oder als Zugmesswertaufnehmer an der Aufnahme des Sicherheitsgurts angeordnet werden. Ein weiterer Vorteil der zugempfindlichen Mittel besteht darin, dass sie die Weitung des Brustkorbs sicher und deutlich erfassen, so dass die Atemfrequenz unabhängig von Störsignalen, welche beispielsweise durch die Fahrzeugbewegung verursacht werden, von der Auswerte- und Steuereinheit eindeutig bestimmt werden kann.According to the invention a sensor device at least one integrated in the safety belt sensitive element, which is a broadening of the ribcage representing Strain signal generated, wherein the sensor device generates the Strain signal to an evaluation and control unit transmits which evaluates the strain signal to determine the respiratory rate of the driver. The susceptible elements are advantageously simple built up and can For example, as strain gauges cost in the safety belt integrated or arranged as a Zugmedwertaufnehmer on the seat of the seat belt become. Another advantage of the sensitive means is in that they capture the expansion of the ribcage safely and clearly, so that the respiratory rate is independent from interfering signals, which are caused for example by the vehicle movement, can be uniquely determined by the evaluation and control unit.
In Ausgestaltung der erfindungsgemäßen Vorrichtung sind die Dehnungsmessstreifen so in den Sicherheitsgurt integriert, dass sie bei einem Fahrer mit durchschnittlichen Körpermaßen im Brustbereich angeordnet sind. Dadurch wird die Signalerfassung bei einem Großteil der potentiellen Fahrer in vorteilhafter Weise weiter verbessert.In Embodiment of the device according to the invention the strain gages are integrated in the safety belt that they are arranged in a driver with average body measurements in the chest area are. As a result, the signal acquisition in a large part of potential driver further improved in an advantageous manner.
In weiterer Ausgestaltung der erfindungsgemäßen Vorrichtung ermittelt die Auswerte- und Steuereinheit die Atemfrequenz fortlaufend und/oder periodisch und erzeugt ein Alarmsignal, wenn die ermittelte Atemfrequenz für eine vorgebbare Zeitspanne einen vorgegebenen Schwellwert unterschreitet. Dies ermöglicht in vorteilhafter Weise, dass ein Abgleiten des Fahrers in einen Schlafzustand erkannt wird, wobei der Schlafzustand beispielsweise durch eine gleichmäßige Abnahme der Bewegungen des Brustkorbs und damit der Atemfrequenz repräsentiert wird. Das Alarmsignal wird beispielsweise an eine akustische Alarmausgabeeinrichtung ausgegeben, welche in Reaktion auf das Alarmsignal von der Auswerte- und Steuereinheit eine akustische Warnmeldung ausgibt.In further embodiment of the device according to the invention determines the Evaluation and control unit, the respiratory rate continuously and / or periodically and generates an alarm signal when the detected respiratory rate for one predetermined period of time falls below a predetermined threshold. This allows in an advantageous manner, that a slipping of the driver in one Sleep state is detected, the sleep state, for example through a uniform decrease the movements of the chest and thus the respiratory rate is represented. The alarm signal is sent, for example, to an acoustic alarm output device issued in response to the alarm signal from the evaluation and control unit outputs an audible warning message.
In weiterer Ausgestaltung der erfindungsgemäßen Vorrichtung umfasst die Auswerte- und Steuereinheit eine Korrektureinheit, welche Signale von Fahrzeugsystemen zur Bestimmung eines Korrekturwertes auswertet, wobei die Auswerte- und Steuereinheit mit dem Korrekturwert eine Fahrzeugbewegung bei der Ermittlung der Atemfrequenz berücksichtigt. Die Fahrzeugsysteme sind beispielsweise als Insassenschutzsystem, ABS-System, ESP-System usw. ausgeführt und stellen beispielsweise Beschleunigungssignale und/oder Geschwindigkeitssignale und/oder Gierwinkelsignale usw. zur Verfügung, aus welchen die Fahrzeugbewegung bestimmt werden kann, so dass insbesondere störende Schwingungen, welche das von den zugempfindlichen Elementen erzeugte Dehnungssignal beeinflussen können, bei der Ermittlung der Atemfrequenz berücksichtigt werden.In Another embodiment of the device according to the invention comprises Evaluation and control unit a correction unit, which signals of vehicle systems evaluates to determine a correction value, wherein the evaluation and control unit with the correction value a Vehicle movement taken into account in determining the respiratory rate. The vehicle systems are for example as occupant protection system, ABS system, ESP system, etc. executed and provide, for example Acceleration signals and / or speed signals and / or Yaw angle signals, etc. are available from which the vehicle movement can be determined, so that in particular disturbing vibrations, which is the strain signal generated by the sensitive elements can influence be taken into account in determining the respiratory rate.
Eine vorteilhafte Ausführungsform der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben. Die einzige Figur zeigt ein Blockdiagramm einer erfindungsgemäßen Vorrichtung zum Überwachen des Zustands eines Fahrers.A advantageous embodiment The invention is illustrated in the drawing and will be described below described.
