Abstract
Die Erfindung betrifft ein Verfahren zum Betreiben eines Kraftfahrzeugs (1) beinhaltend die Anwendung zweier Kriterien: Anhand der Geschwindigkeit und/oder Beschleunigung des Kraftfahrzeugs (1) einerseits und anhand der Erfassung eines Fahrzeuginsassen (2) andererseits wird ermittelt, ob die Gefahr einer Kinetose bei diesem Fahrzeuginsassen besteht.Es ist vorgesehen, dass anhand der Erfassungseinrichtung (14a, 14b, 16) erfasst wird, ob mit einer vorbestimmten Mindestwahrscheinlichkeit der von dieser Erfassungseinrichtung erfasste Fahrzeuginsasse (2) seinen Blick in zumindest einen vorbestimmten Raumwinkelbereich (Ω1) bezüglich des Kraftfahrzeugs (1) richtet oder nicht.The invention relates to a method for operating a motor vehicle (1) including the application of two criteria: On the basis of the speed and / or acceleration of the motor vehicle (1) on the one hand and on the basis of the detection of a vehicle occupant (2) on the other hand, it is determined whether there is a risk of kinetosis It is provided that the detection device (14a, 14b, 16) is used to detect whether there is a predetermined minimum probability that the vehicle occupant (2) detected by this detection device is looking into at least a predetermined solid angle range (Ω1) with respect to the motor vehicle ( 1) judges or not.
Description
Die Erfindung behandelt die Thematik der sogenannten Reisekrankheit (Kinetose) im Auto, wie sie herkömmlicherweise den Beifahrer und Passagiere auf der zweiten Sitzreihe trifft. Bei autonom oder teilautonom fahrenden Kraftfahrzeugen kann auch der Fahrer diese Krankheit bekommen.The invention deals with the subject of so-called motion sickness (kinetosis) in the car, as it conventionally affects the front passenger and passengers on the second row of seats. In the case of autonomous or semi-autonomous motor vehicles, the driver can also get this disease.
Die Erfindung betrifft in diesem Zusammenhang ein Verfahren zum Betreiben eines Kraftfahrzeugs, bei dem anhand der Geschwindigkeit des Kraftfahrzeugs und/oder einer Beschleunigung des Kraftfahrzeugs in zumindest einer Richtung ermittelt wird, ob nach einem entsprechenden ersten Kriterium die Gefahr einer Kinetose für zumindest einen Fahrzeuginsassen besteht und anhand einer Erfassungseinrichtung bezüglich eines Fahrzeuginsassen ermittelt wird, ob nach einem entsprechenden zweiten Kriterium die Gefahr einer Kinetose für diesen Fahrzeuginsassen besteht, und wobei im Falle, dass die Anwendung des ersten und des zweiten Kriteriums jeweils angibt, dass die Gefahr einer Kinetose für den von der Erfassungseinrichtung erfassten Fahrzeuginsassen besteht, eine Warnung an zumindest diesen (oder einen anderen) Fahrzeuginsassen ausgegeben wird. Die Erfindung betrifft auch ein entsprechendes Kraftfahrzeug.In this context, the invention relates to a method for operating a motor vehicle in which, based on the speed of the motor vehicle and / or an acceleration of the motor vehicle in at least one direction, it is determined whether there is a risk of kinetosis for at least one vehicle occupant according to a corresponding first criterion and using a detection device with respect to a vehicle occupant it is determined whether there is a risk of kinetosis for this vehicle occupant according to a corresponding second criterion, and in the event that the application of the first and the second criterion each indicates that the risk of kinetosis for the Detection device detected vehicle occupant exists, a warning is issued to at least this (or another) vehicle occupant. The invention also relates to a corresponding motor vehicle.
Ein solches Verfahren und ein solches Kraftfahrzeug sind aus der
Auch aus der
Die
Nachteilig an allen diesen Verfahren des Standes der Technik ist es, dass sie wegen ihrer Komplexität nicht ausreichend praktikabel sind.It is a disadvantage of all of these prior art processes that they are not sufficiently practicable because of their complexity.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und ein Kraftfahrzeug bereitzustellen, bei beziehungsweise in dem die Kinetose besonders einfach ermittelt werden kann.The invention is now based on the object of providing a method and a motor vehicle in or in which the kinetosis can be determined particularly easily.
Die Aufgabe wird durch ein Verfahren nach Anspruch 1 und ein Kraftfahrzeug nach Anspruch 6 gelöst.The object is achieved by a method according to
Erfindungsgemäß wird somit anhand der Erfassungseinrichtung erfasst, ob nach einer vorbestimmten Mindestwahrscheinlichkeit der in der Erfassungseinrichtung erfasste Fahrzeuginsasse seinen Blick in zumindest einen vorbestimmten Raumwinkelbereich bezüglich des Kraftfahrzeugs richtet oder nicht. Daraus wird dann ermittelt oder geschlossen, ob die Gefahr einer Kinetose nach dem zweiten Kriterium für diesen Fahrzeuginsassen besteht. Wird die Mindestwahrscheinlichkeit erreicht oder überschritten, besteht die Gefahr einer Kinetose nach dem zweiten Kriterium, wird sie unterschritten, sagt das zweite Kriterium, dass die Gefahr einer Kinetose nicht besteht.According to the invention, it is thus detected on the basis of the detection device whether or not the vehicle occupant detected in the detection device directs his gaze into at least a predetermined solid angle range with respect to the motor vehicle according to a predetermined minimum probability. From this it is then determined or concluded whether there is a risk of kinetosis according to the second criterion for this vehicle occupant. If the minimum probability is reached or exceeded, there is a risk of kinetosis according to the second criterion; if it falls below it, the second criterion says that there is no risk of kinetosis.
Besonders einfach und daher in besonderem Maße praktikabel ist es, wenn die Untersuchung des Blickfeldes (vorzugsweise des binokularen Blickfelds oder des Fusionsblickfelds) des Fahrzeuginsassen das einzige Kriterium bezüglich des zweiten Fahrzeuginsassen bildet, also alleine das bereits genannte zweite Kriterium bildet, ohne dass es ein weiteres Teilkriterium gäbe.It is particularly simple and therefore particularly practicable if the examination of the field of vision (preferably the binocular field of vision or the fusion field of vision) of the vehicle occupant forms the only criterion with regard to the second vehicle occupant, i.e. only forms the second criterion already mentioned, without it being another Sub-criterion would exist.
Der zumindest eine vorbestimmte Raumwinkelbereich soll vorzugsweise beinhalten, dass der Fahrzeuginsasse das Fahren des Kraftfahrzeugs so verfolgt, als ob er es selbst führe. Der vorbestimmte Raumwinkelbereich kann insbesondere von der Fahrgeschwindigkeit des Kraftfahrzeugs und/oder zumindest einer dem Kraftfahrzeug zugeordneten Beschleunigung abhängig sein: Bei einem besonders schnell fahrendem Kraftfahrzeug richtet der Fahrer üblicherweise seinen Blick weiter in die Ferne, während er bei langsamer Fahrt eher nach unten knapp vor das Fahrzeug blickt.The at least one predetermined solid angle range should preferably include the fact that the vehicle occupant follows the driving of the motor vehicle as if he were driving it himself. The predetermined solid angle range can be dependent in particular on the driving speed of the motor vehicle and / or at least one acceleration assigned to the motor vehicle: In a particularly fast driving motor vehicle, the driver usually directs his gaze further into the distance, while in slow driving he tends to look down just in front of the Vehicle looks.
Die Nutzung einer Sprachausgabeeinrichtung ist vorteilhaft, weil ein Fahrer, der seinen Blick abwendet, auch keine optischen Einrichtungen auf der Armatur betrachtet.The use of a voice output device is advantageous because a driver who averts his gaze also does not look at any optical devices on the dashboard.
Mittels einer Eingabe kann der Fahrzeuginsasse angeben, ob er die Situation ändern möchte, welche sich darauf bezieht, ob überhaupt ein Fahrzeuginsasse und wenn ja, welcher das Kraftfahrzeug steuert. Bei autonom beziehungsweise teilautonom fahrenden Kraftfahrzeugen kann somit ein designierter Fahrer aufgefordert werden (durch den Warnhinweis), die Führung des Kraftfahrzeugs zu übernehmen und dies durch die entsprechende Eingabe zu bestätigen.By means of an input, the vehicle occupant can indicate whether he would like to change the situation, which relates to it, whether there is a vehicle occupant at all and, if so, who is controlling the motor vehicle. In the case of autonomously or partially autonomously driving motor vehicles, a designated driver can thus be requested (by means of the warning notice) to control the motor vehicle accept and confirm this by entering the relevant information.
Das Erfassen der Haltung und/oder der Ausrichtung zumindest eines Körperteils des Fahrzeuginsassen kann bei dem erfindungsgemäßen Kraftfahrzeug mit einer optischen oder Infrarot-Kamera oder auch mittels eines Eye-Trackers erfolgen. Letztere arbeiten in der Regel mit Infrarotsensoren. Ein Kraftfahrzeug der erfindungsgemäßen Art kann zudem ausgelegt sein, Maßnahmen zu treffen oder zu veranlassen, um einerseits dem vorgesehenen Fahrer eine Führung des Kraftfahrzeugs überhaupt zu ermöglichen (beispielsweise durch selbsttätiges Verfahren und Drehen des Sitzes) und andererseits, um die Gefahr des Auftretens einer Kinetose zu verringern. So kann im Falle, dass die Situation besteht, dass eine Kinetose droht, auf eine andere Fahrweise umgestellt werden. Es können Modi vorgesehen sein, von denen der eine Modus der normale Fahrmodus ist und der zweite Modus beinhaltet, dass langsamer beschleunigt wird als im ersten Modus, zumindest in bestimmten Fahrsituationen. Auch kann die Lüftung im Kraftfahrzeug hochgefahren werden. Die Maßnahmen können auch indirekt dadurch veranlasst werden, dass ein Tipp an den Fahrer gegeben wird, beispielsweise über optische Anzeigen oder eine Sprachausgabe, wie er die Gefahr einer Kinetose verringern kann. Auch kann anstelle der Ansteuerung eines Displays, auf das der Fahrer eher nach unten blickt, auf ein auf die Windschutzscheibe projiziertes Display (Head-over-Display) umgestellt werden.In the motor vehicle according to the invention, the posture and / or the orientation of at least one body part of the vehicle occupant can be detected with an optical or infrared camera or also by means of an eye tracker. The latter usually work with infrared sensors. A motor vehicle of the type according to the invention can also be designed to take or initiate measures on the one hand to enable the intended driver to drive the motor vehicle at all (for example by automatically moving and rotating the seat) and on the other hand to reduce the risk of kinetosis to decrease. In the event that the situation exists that there is a risk of kinetosis, you can switch to a different driving style. Modes can be provided, of which one mode is the normal driving mode and the second mode includes that the acceleration is slower than in the first mode, at least in certain driving situations. The ventilation in the motor vehicle can also be started up. The measures can also be initiated indirectly in that a tip is given to the driver, for example via visual displays or voice output, as to how he can reduce the risk of kinetosis. Instead of activating a display at which the driver tends to look down, it is also possible to switch to a display projected onto the windshield (head-over display).

In dem Kraftfahrzeug
Die Messwerte der Einrichtung
Es gibt typische Situationen einer Beschleunigung und/oder bei hohen Geschwindigkeiten, in denen ein auf ein Buch oder einen Bildschirm blickender Fahrzeuginsasse Gefahr läuft, Opfer der Kinetose (Reisekrankheit) zu werden, das heißt, ihm wird schwindlig und übel. Circa 60 bis 80% aller Personen haben bereits Erfahrungen mit Symptomen einer Kinetose gemacht. Mit steigendem Automatisierungsgrad der Kraftfahrzeuge wird in Zukunft auch der designierte Fahrer zum Passagier und kann sich Nebenaufgaben, wie zum Beispiel dem Lesen oder Ansehen von Filmen widmen. Der Fahrer selbst ist in der Regel nicht von einer Kinetose betroffen, wenn er das Kraftfahrzeug aktiv steuert. Die Symptomatik der Kinetose mit Unwohlsein, Übelkeit bis hin zum Erbrechen führt dazu, dass Personen im Kraftfahrzeug nicht mehr Nebentätigkeiten wie etwa Lesen und Betrachten von Filmen vollziehen können. Dadurch wird gerade der Vorteil des autonomen Fahrens, dass den Fahrzeuginsassen Zeit zur Verfügung steht, in der das Fahrzeug automatisiert fährt, wieder zum Teil beseitigt und die Akzeptanz der Kunden für die Technologie des automatisierten Fahrens verringert sich. Ein von der Kinetose betroffener designierter Fahrzeugführer kann auch nur schlecht oder langsam im Falle der Notwendigkeit schnell und kurzfristig das Führen des Kraftfahrzeugs übernehmen.There are typical situations of acceleration and / or at high speeds in which a vehicle occupant looking at a book or a screen runs the risk of becoming a victim of motion sickness (motion sickness), that is to say of becoming dizzy and nauseous. Around 60 to 80% of all people have already had symptoms of kinetosis. With the increasing degree of automation in motor vehicles, the designated driver will also become a passenger in the future and can devote himself to secondary tasks such as reading or watching films. As a rule, the driver himself is not affected by kinetosis when he is actively controlling the motor vehicle. The symptoms of kinetosis with malaise, nausea and even vomiting mean that people in the motor vehicle are no longer able to carry out secondary activities such as reading and watching films. As a result, the advantage of autonomous driving that the vehicle occupants have the time during which the vehicle is driving automatically becomes part of it again eliminated and customer acceptance of automated driving technology is reduced. A designated vehicle driver affected by the kinetosis can also take over the driving of the motor vehicle quickly and for a short time only poorly or slowly, if necessary.
