1 schematisch einen Ausschnitt einer Instrumententafel eines Fahrzeuges mit einem einen Fahrer zugeordneten Anzeigebereich. 1 schematically a section of an instrument panel of a vehicle with a driver associated with a display area.

In der einzigen Figur ist ein Ausschnitt einer Instrumententafel eines nicht näher dargestellten Fahrzeuges mit einem einen Fahrer des Fahrzeuges zugeordneten Anzeigebereich 1 dargestellt. In dem Anzeigebereich 1 sind zwei Skalenanzeigen 1.1, in Form eines Tachometers und eines Drehzahlmessers, Richtungsanzeiger 1.2 und grafische Symbole 1.3 zur Information des Fahrers dargestellt.In the single figure is a section of an instrument panel of a vehicle not shown with a driver of the vehicle associated display area 1 shown. In the display area 1 are two scale indications 1.1 , in the form of a tachometer and a tachometer, direction indicator 1.2 and graphic symbols 1.3 presented for the information of the driver.

Das Fahrzeug verfügt über eine nicht näher dargestellte Vorrichtung zur Überwachung und Ermittlung eines Fahrerzustandes des Fahrers, wobei ein Maß der Schwere einer Unaufmerksamkeit und/oder Müdigkeit ermittelt wird.The vehicle has a device, not shown, for monitoring and determining a driver's condition of the driver, wherein a measure of the severity of inattention and / or fatigue is determined.

Der Fahrerzustand wird anhand erfasster Signale zumindest einer als hochauflösender Lenkwinkelsensor ausgeführten Erfassungseinheit ermittelt, wobei die erfassten Signale einer Steuereinheit, die mit der Erfassungseinheit verbunden ist, zugeführt werden. Mittels der Steuereinheit werden die erfassten Signale verarbeitet und ausgewertet.The driver state is determined on the basis of detected signals of at least one detection unit designed as a high-resolution steering angle sensor, the detected signals being fed to a control unit which is connected to the detection unit. By means of the control unit, the detected signals are processed and evaluated.

Dazu sind bevorzugt in der Steuereinheit Lenkmuster hinterlegt, die mit den erfassten Signalen verglichen werden, wodurch der Fahrerzustand als Maß der Schwere der Unaufmerksamkeit und/oder Müdigkeit bestimmt wird.For this purpose, steering patterns are preferably stored in the control unit, which are compared with the detected signals, whereby the driver state is determined as a measure of the severity of inattentiveness and / or fatigue.

In Abhängigkeit des ermittelten Maßes der Schwere der Unaufmerksamkeit und/oder Müdigkeit kann ein Warnhinweis und/oder eine Empfehlung, wie z. B. eine Pause einzulegen, akustisch, optisch und/oder haptisch an den Fahrer des Fahrzeuges ausgegeben werden. Vorzugsweise werden bzw. wird der Warnhinweis und/oder die Empfehlung optisch mittels eines nicht näher dargestellten Piktogramms, beispielsweise in Form einer Kaffeetasse auf dem Anzeigebereich der Instrumententafel, ausgegeben.Depending on the determined extent of the severity of inattention and / or fatigue, a warning and / or a recommendation, such. B. to take a break, acoustically, visually and / or haptically issued to the driver of the vehicle. Preferably, the warning and / or the recommendation are optically output by means of a pictogram not shown in detail, for example in the form of a coffee cup on the display area of the instrument panel.

Zusätzlich zu der Überwachung und Ermittlung des Fahrerzustandes in Form des Maßes der Aufmerksamkeit anhand des erfassten Lenkverhaltens ist vorgesehen, eine Zeitdauer von beispielsweise 4 Stunden vorzugeben, die sich im Betrieb des Fahrzeuges, also mit zunehmender Fahrdauer kontinuierlich vermindert, wobei die vorgegebene Zeitdauer und deren kontinuierliche Verringerung das Maß der Aufmerksamkeit des Fahrers widerspiegelt.In addition to the monitoring and determination of the driver state in the form of the measure of attention based on the detected steering behavior is provided to specify a period of, for example, 4 hours, which decreases continuously during operation of the vehicle, so with increasing driving time, the predetermined time duration and its continuous Reducing the level of driver's attention.

Die vorgegebene Zeitdauer kann in Prozent in dem Anzeigebereich 1 der Instrumententafel mittels einer Balkenanzeige 1.4 dargestellt werden, wobei die Balkenanzeige 1.4 zum Fahrtantritt vollständig gefüllt ist und sich in Bezug auf die Fahrdauer prozentual kontinuierlich verringert, da sich die Aufmerksamkeit in Abhängigkeit der Fahrdauer verringert.The predetermined period of time may be in percent in the display area 1 the instrument panel by means of a bar graph 1.4 being represented, the bar graph 1.4 is completely filled to start driving and continuously reduced in percentage with respect to the driving time, since the attention decreases depending on the driving time.

In dem vorliegenden Ausführungsbeispiel gemäß 1 ist die Balkenanzeige 1.4 bis zur Hälfte gefüllt, wodurch ersichtlich ist, dass der Fahrer das Fahrzeug, sofern die Zeitdauer mit 4 Stunden vorgegeben ist, seit 2 Stunden ohne Unterbrechung, welche insbesondere aus einem Ausschaltens der Zündung resultieren kann, führt.In the present embodiment according to 1 is the bar graph 1.4 filled up to half, which shows that the driver, the vehicle, if the time is given with 4 hours, for 2 hours without interruption, which may in particular result from switching off the ignition results.

Wie oben beschrieben, wird der Fahrerzustand einerseits anhand des erfassten Lenkverhaltens und andererseits durch die kontinuierliche Verminderung der Zeit hinsichtlich der Fahrdauer des Fahrers ermittelt.As described above, the driver state is determined on the one hand on the basis of the detected steering behavior and on the other hand by the continuous reduction of the time with respect to the driving time of the driver.

Dabei wird der Fahrerzustand, insbesondere das Maß der Schwere der Unaufmerksamkeit und/oder Müdigkeit durch die vorgegebene Zeitdauer ermittelt, da man im Allgemeinen davon ausgehen kann, dass die Aufmerksamkeit des Fahrers mit zunehmender Fahrdauer abnimmt.In this case, the driver state, in particular the degree of severity of inattention and / or fatigue, is determined by the predetermined period of time, since it can generally be assumed that the driver's attention decreases with increasing driving time.

Insbesondere ist vorgesehen, dass die mittels der Balkenanzeige 1.4 prozentual ausgegebene Zeitdauer in Bezug auf die Fahrdauer bei einer aktiven und/oder dynamischen Fahrweise langsamer verringert wird als bei einer passiven und/oder monotonen Fahrweise des Fahrzeuges. Durch das unterschiedlich schnelle Verringern der Zeit in Abhängigkeit der Fahrweise, mittels welcher der Fahrerzustand dargestellt wird, ist es möglich, ein subjektives Fahrerempfinden abzubilden.In particular, it is provided that the means of the bar display 1.4 percentage spent time is reduced in relation to the driving time at an active and / or dynamic driving slower than in a passive and / or monotonous driving style of the vehicle. By reducing the time differently depending on the driving style by means of which the driver state is displayed, it is possible to depict a subjective driver's perception.

Die Ermittlung des Fahrerzustandes hinsichtlich des Maßes der Schwere der Unaufmerksamkeit und/oder Müdigkeit in Abhängigkeit der Fahrweise kann bevorzugt erfolgen, wenn in dem Fahrzeug eine Fahrstilbewertung, z. B. über eine Längsbeschleunigung, Querbeschleunigung und/oder Fahrpedalbetätigung durchgeführt werden kann.The determination of the driver state with regard to the degree of severity of inattentiveness and / or fatigue as a function of the driving style can preferably take place when a driving style evaluation, eg. B. via a longitudinal acceleration, lateral acceleration and / or accelerator pedal operation can be performed.

Wie oben beschrieben, wird das Maß der Schwere der Unaufmerksamkeit und/oder Müdigkeit des Fahrers anhand der Lenkmustererkennung durchgeführt, wobei mittels der Vorgabe der Zeit, welche mit steigender Fahrdauer kontinuierlich abnimmt, parallel eine Bewertung des Fahrerzustandes durchgeführt wird.As described above, the degree of severity of the inattention and / or fatigue of the driver is performed based on the steering pattern recognition, whereby an estimation of the driver condition is performed in parallel by setting the time, which decreases continuously as the driving time increases.

Die vorgegebene Zeit und deren kontinuierliche Verringerung wird mittels der Balkenanzeige 1.4 in dem Anzeigebereich 1 der Instrumententafel an den Fahrer ausgegeben, so dass der Fahrer fortlaufend über den Fahrzustand und das damit verbundene Maß der Schwere der Aufmerksamkeit oder Unaufmerksamkeit und/oder Müdigkeit informiert wird.The predetermined time and its continuous reduction is indicated by the bar graph 1.4 in the display area 1 issued to the driver of the instrument panel so that the driver is continuously informed about the driving condition and the associated degree of severity of attention or inattention and / or fatigue.

Dabei wird die Ermittlung des Maßes der Schwere der Unaufmerksamkeit und/oder Müdigkeit mittels der kontinuierlichen Verringerung der vorgegebenen Zeit auch durchgeführt, wenn sich die Ermittlung des Fahrerzustandes durch Erfassen des Lenkverhaltens im passiven Zustand befindet.Here, the determination of the degree of severity of inattention and / or fatigue by means of the continuous reduction of the predetermined time is also performed when the determination of the driver state by detecting the steering behavior is in the passive state.

Durch die Anzeige der Balkenanzeige 1.4 im Anzeigebereich 1 der Instrumententafel oder in einem anderen für den Fahrer sichtbaren Anzeigebereich, wobei mittels der Balkenanzeige prozentual die Zeit und deren Verringerung angezeigt wird, ist die Bewertung des Fahrerzustandes hinsichtlich der Unaufmerksamkeit und/oder Müdigkeit des Fahrers in besonders vorteilhafter Weise für denselben nachvollziehbar.By displaying the bar graph 1.4 in the display area 1 the instrument panel or in another visible to the driver display area, wherein by means of the bar display the percentage time and the reduction is displayed, the evaluation of the driver's condition regarding inattentiveness and / or fatigue of the driver in a particularly advantageous manner for the same traceable.
