Verfahren zum Betreiben eines Kraftfahrzeugs sowie Kraftfahrzeug Method for operating a motor vehicle and motor vehicle
Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Kraftfahrzeugs, bei dem der Fahrzeugführer durch zumindest eine Überwachungseinrichtung des Kraftfahrzeugs überwacht wird und das Ergebnis dieser Überwachung ausgewertet wird, um vermeiden zu können, dass ein abgelenkter Fahrzeugführer eine Gefahrensituation hervorruft. The present invention relates to a method for operating a motor vehicle, in which the vehicle driver is monitored by at least one monitoring device of the motor vehicle and the result of this monitoring is evaluated in order to be able to prevent a distracted vehicle driver from causing a dangerous situation.
Dies ist an sich bekannt. Beispielsweise beschreibt die US 2018/0 319407 A1 ein Verfahren, bei dem die Überwachungseinrichtung als Kamerasystem ausgebildet ist, mittels dessen der Fahrzeugführer beobachtet wird. Die Kamerabilder werden dahingehend ausgewertet, ob der Fahrer auf die Straße blickt oder durch Blickabwendung von der Straße abgelenkt ist. Des Weiteren kann erkannt werden, ob der Fahrer von einem autonomen Fährbetrieb in einen manuellen Fährbetrieb wechseln möchte. Falls dies der Fall ist, wird ein Fahrersitz automatisch in eine passende Stellung verfahren, in welcher der Fahrer die Fahraufgabe übernehmen kann. This is known per se. For example, US 2018/0 319407 A1 describes a method in which the monitoring device is designed as a camera system, by means of which the vehicle driver is observed. The camera images are evaluated to determine whether the driver is looking at the road or is distracted by looking away from the road. Furthermore, it can be recognized whether the driver wants to switch from autonomous ferry operation to manual ferry operation. If this is the case, a driver's seat is automatically moved to a suitable position in which the driver can take over the task of driving.
Auch aus der US 10 336 323 B2 ist es bekannt, die Blickrichtung eines Fahrzeugführers eines Kraftfahrzeugs zu erfassen. In Abhängigkeit von einer erkannten Blickrichtung wird entschieden, ob Signale an ein Unfallverhütungssystem des Kraftfahrzeugs übermittelt werden. Für verschiedene Fahrzeugführer können unterschiedliche Ablenkungsgrade vorgesehen sein, wobei in Abhängigkeit vom Ablenkungsgrad die Anzahl der mittels des Unfallverhütungssystems ausgegebenen Warnungen festgelegt wird und festgelegt wird, in welchem Ausmaß auf einem Display des Fahrzeugs weniger relevante Informationen angezeigt werden. It is also known from US Pat. No. 10,336,323 B2 to detect the viewing direction of a vehicle driver of a motor vehicle. Depending on a recognized viewing direction, a decision is made as to whether signals are to be transmitted to an accident prevention system in the motor vehicle. Different degrees of distraction can be provided for different vehicle drivers, the number of warnings issued by the accident prevention system being determined as a function of the degree of distraction and the extent to which less relevant information is shown on a display of the vehicle.
Die DE 102017 204424 A1 beschreibt ein Verfahren zum Bereitstellen eines Nutzungsprofils eines Benutzers eines Kraftfahrzeugs. Das Nutzungsprofil beschreibt das Nutzungsverhalten eines Fahrers in Bezug auf eine Komforttechnikfunktion. Benutzt derselbe Benutzer später ein anderes Kraftfahrzeug, so wird geprüft, ob die Komforttechnikfunktion aktuell in einem aktivierten Zustand bereitgestellt ist. Des Weiteren wird geprüft, ob eine Gefahrensituation vorliegt. Ist die Komforttechnikfunktion deaktiviert und liegt zugleich eine Gefahrensituation vor, so wird ein Warnsignal erzeugt, das den betreffenden Benutzer auf die Gefahrensituation aufmerksam macht. Generell ist es bekannt, dass Infotainmentsysteme im Auto nicht nur für mehr Komfort sorgen, sondern auch das Unfallrisiko steigern, weil der Fahrzeugführer durch sie ablenkbar ist. Fahrzeugführer, die sich durch die Nutzung des Navigationssystems oder durch die Nutzung des Bordcomputers ablenken lassen, weisen höhere Unfallraten auf, als sie bei Fahrzeugführern vorkommen, die nicht über derartige Ablenkungsquellen verfügen. Gerade besondere Komfortfunktionen beim Bedienen wie das Blättern im Navigationsmenü, die Bedienung der Klimaanlage im Fahrzeug, oder das Ablesen von beim Fahren momentan gültigen Tempolimits vom Head-up-Display lenken den Fahrer vom sicheren Führen des Kraftfahrzeugs ab. Das reine Abschalten oder Verbieten von Fahrzeugfunktionen oder Bedienung während der Fahrt mindert genau den Komfort, der durch die Bedienfunktionen gegeben sein sollte. Manche Fahrzeugführer greifen beim Fahren auf Smartphones zurück, um etwa Funktionen wie Navigation, Kommunikation oder Entertainment zu nutzen, wenn die Verwendung derartiger Funktionen durch Fahrzeugsysteme unterbunden wird. Auch eine reine Warnung ist nicht immer hilfreich. DE 102017 204424 A1 describes a method for providing a user profile of a user of a motor vehicle. The usage profile describes the usage behavior of a driver in relation to a comfort technology function. If the same user later uses a different motor vehicle, it is checked whether the convenience technology function is currently provided in an activated state. Furthermore, it is checked whether a dangerous situation exists. If the comfort technology function is deactivated and there is a dangerous situation at the same time, a warning signal is generated which draws the user's attention to the dangerous situation. It is generally known that infotainment systems in cars not only provide more comfort, but also increase the risk of accidents because the driver can be distracted by them. Vehicle drivers who allow themselves to be distracted by using the navigation system or by using the on-board computer have higher accident rates than vehicle drivers who do not have such sources of distraction at their disposal. In particular, special comfort functions when operating such as scrolling through the navigation menu, operating the air conditioning in the vehicle, or reading the current speed limit while driving from the head-up display distract the driver from driving the vehicle safely. Simply switching off or prohibiting vehicle functions or operation while driving reduces exactly the comfort that should be provided by the operating functions. Some vehicle drivers use smartphones while driving, for example to use functions such as navigation, communication or entertainment if the use of such functions is prevented by vehicle systems. Even a mere warning is not always helpful.
Es ist die Aufgabe der vorliegenden Erfindung, einen Weg aufzuzeigen, wie das Kraftfahrzeug den Fahrzeugführer so anleitet, dass dieser sich weniger bevormundet führt, ohne dass Sicherheitsaspekte vernachlässigt werden. It is the object of the present invention to show a way in which the motor vehicle guides the vehicle driver in such a way that he behaves in a less patronizing manner, without safety aspects being neglected.
Die Aufgabe wird durch ein Verfahren zum Betreiben eines Kraftfahrzeugs, bei dem der Fahrzeugführer durch zumindest eine Überwachungseinrichtung des Kraftfahrzeugs überwacht wird, gelöst, bei dem geprüft wird, ob durch eine Bedienabsicht oder eine bereits erfolgende Bedienhandlung eine Ablenkung des Fahrzeugführers besteht. Durch zumindest eine Überwachungseinrichtung wird bei der Erfindung eine manuelle Betätigung von Bedieneinheiten überwacht und bei nach dem vorbestimmten Kriterium bestehender Ablenkung des Fahrzeugführers wird diesem durch das Kraftfahrzeug eine alternative Bedienart angeboten oder aufgezwungen. The object is achieved by a method for operating a motor vehicle, in which the driver is monitored by at least one monitoring device of the motor vehicle, in which it is checked whether the driver is distracted by an operating intention or an operating action that has already taken place. In the invention, at least one monitoring device monitors manual actuation of operating units and, if the vehicle driver is distracted according to the predetermined criterion, an alternative operating mode is offered or forced on him by the motor vehicle.
Die alternative Bedienart kann darin bestehen, dass die manuelle Bedienung durch die Bedieneinheit vereinfacht wird, also Funktionen weniger komplex sind, als sie sonst durch das Kraftfahrzeug dem Fahrzeugführer angeboten werden. The alternative operating mode can be that the manual operation is simplified by the operating unit, ie functions are less complex than they are otherwise offered to the vehicle driver by the motor vehicle.
Die alternative Bedienung beinhaltet bei einem Ausführungsbeispiel, dass die Bedieneinheit oder -einheiten auf eine Bedienung mittels Sprachsteuerung wechseln, eben anstelle der manuellen Betätigung. Schließlich könnte auch dem Fahrzeugführer angeboten werden, dass die Bedienung durch den Beifahrer erfolgt, wobei zu diesem Zweck dem Fahrzeugführer und dem Beifahrer beispielsweise Pfeile und/oder ein Blinken an der Seite des Beifahrers gezeigt werden und/oder Befehle auf dem Display oder Sprachbefehle gegeben werden. In one embodiment, the alternative operation includes the operating unit or units switching to operation by means of voice control instead of manual operation. Finally, the vehicle driver could also be offered the option of being operated by the passenger, for which purpose the vehicle driver and the passenger are shown arrows and/or a flashing light on the side of the passenger, for example, and/or commands are given on the display or voice commands are given .
Bei einem Ausführungsbeispiel beinhaltet das vorbestimmte Kriterium, dass sämtliche Tätigkeiten aus einer vorbestimmten Gruppe von solchen Tätigkeiten des Fahrzeugführers berücksichtigt werden, welche nicht unmittelbar mit einer Steuerung des Kraftfahrzeugs Zusammenhängen. Solche Tätigkeiten können beinhalten, dass der Fahrzeugführer ein Infotainmentsystem bedient, wobei auch die Bedienung eines Navigationsgeräts unter diesen Aspekt fallen kann, dass der Bordcomputer bedient wird und/oder dass der Fahrzeugführer an der Armatur des Kraftfahrzeugs Schaltvorgänge und ähnliche Bedienhandlungen vornimmt („Blättern im Menü“). In one embodiment, the predetermined criterion includes that all activities from a predetermined group of such activities of the vehicle driver are taken into account, which are not directly related to a control of the motor vehicle. Such activities can include the vehicle driver operating an infotainment system, whereby the operation of a navigation device can also fall under this aspect, the on-board computer being operated and/or the vehicle driver carrying out switching operations and similar operating actions on the vehicle dashboard ("scrolling through the menu ").
Bei einem Ausführungsbeispiel der Erfindung trägt jede der Tätigkeiten aus der vorbestimmten Gruppe zur Festlegung eines Zahlenwerts bei. Das vorbestimmte Kriterium beinhaltet dann, dass ein Wert jenseits eines Schwellwerts für den Zahlenwert erreicht wird (beispielweise kann beim Aufaddieren von Zahlenwerten das Überschreiten eines Schwellwerts nach oben hin erfasst werden). Den Tätigkeiten können auch solche Zahlenwerte oder sonstige binäre Informationen und dergleichen zugeordnet werden, die anders als durch reine Addition miteinander verarbeitet werden. Beispielsweise kann eine Multiplikation mehrerer Zahlenwerte, dies etwa in Teilgruppen, erfolgen. Auch kann der Zahlenwert bei bestimmten Tätigkeiten abgezogen werden oder als Quotient bei einer Division fungieren. In one embodiment of the invention, each of the actions in the predetermined group contributes to establishing a numerical value. The predetermined criterion then includes that a value beyond a threshold value for the numerical value is reached (for example, when numerical values are added up, exceeding a threshold value upwards can be detected). Numerical values or other binary information and the like can also be assigned to the activities, which are processed with one another other than by pure addition. For example, a number of numerical values can be multiplied, for example in subgroups. The numerical value can also be subtracted for certain activities or act as a quotient in a division.
Bei einem Ausführungsbeispiel ist vorgesehen, dass der Schwellwert zumindest von einem Grad eines teilautonomen Fahrens des Kraftfahrzeugs abhängig definiert wird. Dadurch können dem Fahrzeugführer desto mehr Bedienhandlungen ermöglicht werden, je mehr das Kraftfahrzeug teilautonom fährt. Dadurch fühlt sich der Fahrzeugführer weniger bevormundet. In one exemplary embodiment, it is provided that the threshold value is defined as a function of at least one degree of semi-autonomous driving of the motor vehicle. As a result, the more operator actions are enabled for the vehicle driver, the more the motor vehicle drives semi-autonomously. As a result, the vehicle driver feels less patronized.
Bei einem Ausführungsbeispiel wird durch zumindest eine Beobachtungseinrichtung des Kraftfahrzeugs die Verkehrssituation beobachtet und der Schwellwert zumindest von einem Grad einer notwendigen Aufmerksamkeit des Fahrzeugführers abhängig definiert. Auch hier besteht das Ziel darin, dem Fahrzeugführer möglichst viele Bedienhandlungen zu ermöglichen, wenn dies die Verkehrssituation zulässt. Die Tätigkeiten aus der vorbestimmten Gruppe können auf unterschiedliche Weise zu dem Zahlenwert beitragen. Beispielsweise kann bei Bedienung des Navigationssystems eine höhere Punktezahl zu einem Zahlenwert beitragen als eine Bedienhandlung an einer Armatur, wo einfach durchgeblättert wird, um das Display zu ändern. In one exemplary embodiment, the traffic situation is observed by at least one observation device of the motor vehicle and the threshold value is defined as a function of at least a degree of necessary attention on the part of the vehicle driver. Here, too, the aim is to enable the vehicle driver to carry out as many operating actions as possible if the traffic situation permits. The activities from the predetermined group can contribute to the numerical value in different ways. For example, when operating the navigation system, a higher score can contribute to a numerical value than an operator action on a dashboard, where you simply scroll through to change the display.
Die zumindest eine Überwachungseinrichtung erfasst in einem Ausführungsbeispiel a) den Blick des Fahrzeugführers, und/oder b) eine Sitzbelegung auf dem Beifahrersitz und c) eine Hand oder Finger an einer Bedieneinheit, wobei im Falle c) diese entweder dem Fahrzeugführer oder einem anderen Insassen, typischerweise dem Beifahrer, zugeordnet wird. Aus den so erfassten Informationen kann abgeleitet werden, ob die Bedienabsicht oder die bereits erfolgende Bedienhandlung tatsächlich diejenige des Fahrzeugführers ist, und nicht die des Beifahrers. Wird erfasst, dass der Beifahrer die Bedienung vornehmen möchte beziehungsweise vornimmt, muss keine alternative Bedienart angeboten oder aufgezwungen werden. In one exemplary embodiment, the at least one monitoring device detects a) the gaze of the vehicle driver, and/or b) a seat occupancy on the front passenger seat and c) a hand or finger on an operating unit, whereby in the case of c) this either belongs to the vehicle driver or to another occupant, typically the passenger. From the information recorded in this way, it can be derived whether the operating intention or the operating action that has already taken place is actually that of the vehicle driver and not that of the front passenger. If it is detected that the front passenger would like to carry out the operation or is carrying out the operation, no alternative type of operation has to be offered or forced.
Die Überwachungseinrichtung kann zu den vorgenannten Zwecken zumindest eine Kamera oder mehrere Kameras umfassen, sodass die Erfassung des Blicks, der Sitzbelegung beziehungsweise auch der Hand und des entsprechenden Bedienenden anhand von Kamerabildern erfolgt. For the aforementioned purposes, the monitoring device can comprise at least one camera or a plurality of cameras, so that the gaze, the seat occupancy or also the hand and the corresponding operator are recorded using camera images.
Die Aufgabe wird auch durch ein Kraftfahrzeug mit einer Bedieneinheit gelöst, und zumindest einer Einrichtung zum Erfassen zumindest eines von: The object is also achieved by a motor vehicle with an operating unit and at least one device for detecting at least one of:
- der Belegung von Fahrersitz und/oder Beifahrersitz, - the occupancy of the driver's seat and/or front passenger seat,
- den Blick des Fahrzeugführers und/oder des Beifahrers, - the view of the driver and/or the passenger,
- die Bewegung zumindest einer Hand des Fahrzeugführers und/oder des Beifahrers, und - the movement of at least one hand of the driver and/or the passenger, and
- die Bewegung eines Fingers des Fahrzeugführers und/oder des Beifahrers - the movement of a finger by the driver and/or the passenger
Das Kraftfahrzeug weist des Weiteren Mittel zum Ableiten eines Grades einer Ablenkung des Fahrzeugführers anhand der von der Einrichtung zum Erfassen gewonnenen Informationen auf sowie Mittel zum Ändern der Bedienart bei so erkannter Ablenkung des Fahrzeugführers. The motor vehicle also has means for deriving a degree of distraction of the vehicle driver based on the information obtained from the detection device and means for changing the operating mode when the driver's distraction is detected in this way.
Die Vorteile des erfindungsgemäßen Verfahrens sind gleichermaßen auch Vorteile des erfindungsgemäßen Kraftfahrzeugs, denn es bestehen erweiterte Möglichkeiten, beim Fahren Bedienhandlungen vorzunehmen. Bei einem Ausführungsbeispiel umfasst die Einrichtung zum Erfassen zumindest eine Kamera, wobei typischerweise gleich eine Mehrzahl von Kameras vorgesehen ist. The advantages of the method according to the invention are also advantages of the motor vehicle according to the invention, because there are extended possibilities for carrying out operator actions while driving. In one exemplary embodiment, the device for detecting comprises at least one camera, with a plurality of cameras typically being provided at the same time.

Gleiche oder funktionsgleiche Elemente sind in den Figuren mit den gleichen Bezugszeichen versehen. Elements that are the same or have the same function are provided with the same reference symbols in the figures.
Ein in Fig. 1 schematisch gezeigtes und im Ganzen mit 1 bezeichnetes Kraftfahrzeug umfasst den Fahrersitz 10 und den Beifahrersitz 12 sowie weitere Sitze 14. Ein Kamerasystem, hier symbolisch durch eine einzige Kamera 16 veranschaulicht, beinhaltet eine oder mehrere Kameras zur Beobachtung des Fahrzeug-Cockpits. Anhand der Kamerabilder wird abgeleitet, welche der Sitze 10, 12 und 14 im Kraftfahrzeug belegt sind. Eine Bedieneinheit 18 lässt sich vom Fahrzeugführer auf dem Fahrersitz 10 manuell bedienen. Mittels der gewonnenen Bilder des Kamerasystems 16 wird neben der Sitzbelegung nun erfasst, wohin der Fahrer auf dem Fahrersitz 10 blickt - auf die Straße oder auf die Bedieneinrichtung 18 - und in welche Richtung sich seine Hand beziehungsweise einzelne Finger einer Hand bewegen. Aus den mittels des Kamerasystems 16 gewonnenen Kamerabildern kann auch abgeleitet werden, wenn ein auf dem Beifahrersitz 12 sitzender Beifahrer anwesend ist und Bedienhandlungen plant oder vornimmt. In einer Steuereinrichtung 20 ist Software in Form geeigneter Algorithmen abgelegt, die die Kamerabilder entsprechend auswertet. Die genannten Informationen werden als Zahlenwerte dargestellt, die gemeinsam mittels der Software 22 zur Ableitung eines Zahlenwertes genutzt werden. Beispielsweise kann der Zahlenwert so definiert sein, dass mit größerer Ablenkung des Fahrzeugführers auf dem Fahrersitz 10 der Zahlenwert steigt. In diesem Falle wäre dann ein Schwellwert zu definieren, bei dessen Erreichen oder Überschreiten der Fahrzeugführer als abgelenkt gilt. Der Schwellwert kann variabel sein und beispielsweise von den mittels einer Beobachtungseinrichtung 24 zum Erfassen der Verkehrssituation gewonnenen Informationen abhängig sein, oder auch von einer Funktion 26, die durch die Steuereinrichtung 20 umgesetzt wird und sich auf den Grad der Autonomie des Fahrens des Kraftfahrzeugs bezieht. Hier kann eine Staffelung von reinem autonomen Fahren, Verwendung eines sogenannten Staupiloten, Autobahnpiloten und dergleichen vorgenommen sein. A motor vehicle shown schematically in Fig. 1 and denoted as a whole by 1 comprises the driver's seat 10 and the front passenger's seat 12 as well as further seats 14. A camera system, symbolically illustrated here by a single camera 16, contains one or more cameras for observing the vehicle cockpit . The camera images are used to derive which of the seats 10, 12 and 14 in the motor vehicle are occupied. An operating unit 18 can be operated manually by the vehicle driver on the driver's seat 10 . By means of the images obtained by the camera system 16, in addition to the seat occupancy, it is now recorded where the driver is looking from the driver's seat 10—at the road or on the operating device 18 - and in which direction his hand or individual fingers of a hand move. From the camera images obtained by means of the camera system 16, it can also be derived when a passenger sitting on the passenger seat 12 is present and is planning or carrying out operator actions. Software in the form of suitable algorithms is stored in a control device 20 and evaluates the camera images accordingly. The information mentioned is presented as numerical values which are used together by means of the software 22 to derive a numerical value. For example, the numerical value can be defined such that the greater the distraction of the driver of the vehicle on the driver's seat 10, the numerical value increases. In this case, a threshold value would then have to be defined, upon reaching or exceeding which the vehicle driver is deemed to be distracted. The threshold value can be variable and be dependent, for example, on the information obtained by means of an observation device 24 for detecting the traffic situation, or also on a function 26 which is implemented by the control device 20 and relates to the degree of autonomous driving of the motor vehicle. Here, purely autonomous driving, use of a so-called traffic jam pilot, highway pilot and the like can be differentiated.
Im Falle, dass mittels des Schwellwertkriteriums festgestellt wird, dass der Fahrzeugführer in zu großem Maße abgelenkt ist, um das Fahrzeug sicher zu führen, wird auf der manuell betätigbaren Bedieneinheit eine Warnung oder eine Empfehlung optisch ausgegeben. Dies kann derart ausgestaltet sein, dass der Fahrzeugführer der Warnung und Empfehlung Folge leisten kann oder Folge leisten muss. Als alternative Bedienart kann der Fahrer Mikrofone 28 nutzen, die im Kraftfahrzeug 1 verbaut sind, um die Bedienhandlungen über die Sprache vorzunehmen, um also Sprachbefehle abzugeben. Generell kann hier jede „digitale Assistenz“ aktiviert werden. If the threshold value criterion is used to determine that the vehicle driver is too distracted to drive the vehicle safely, a warning or a recommendation is output optically on the manually operable control unit. This can be designed in such a way that the driver of the vehicle can or must follow the warning and recommendation. As an alternative operating mode, the driver can use microphones 28 that are installed in motor vehicle 1 in order to carry out the operating actions via voice, ie to issue voice commands. In general, any "digital assistance" can be activated here.
Das erfindungsgemäße Verfahren beinhaltet, dass in Schritt S10 die Situation im Cockpit erfasst wird wie oben beschrieben, dass im Schritt S12 die Verkehrssituation beobachtet wird, dass im Schritt S14 mittels des Algorithmus 22 in der Steuereinrichtung 20 geprüft wird, ob der Fahrer in Anbetracht der Verkehrssituation in zu großem Maße nach einem vorbestimmten Schwellwertkriterium abgelenkt ist. Ist dies nicht der Fall, wird zum Schritt S10 zurückgekehrt, alternativ zum Schritt S12. Ist dies der Fall, wird hingegen zum Schritt S16 übergegangen, in dem eine Bedienhandlung, wie sie gerade vorgenommen wird oder werden sollte, unterbunden oder zumindest abempfohlen wird und eine alternative Bedienart aufgezeigt (empfohlen) und insbesondere ermöglicht wird, falls sie zuvor nicht gegeben war. Bezugszeichenhste The method according to the invention includes that in step S10 the situation in the cockpit is detected as described above, that in step S12 the traffic situation is observed, that in step S14 the algorithm 22 in the control device 20 is used to check whether the driver, in view of the traffic situation is deflected to an excessive extent after a predetermined threshold criterion. If this is not the case, a return is made to step S10, alternatively to step S12. If this is the case, on the other hand, there is a transition to step S16, in which an operator action as it is or should be carried out is prevented or at least discouraged and an alternative operating mode is shown (recommended) and in particular enabled if it was not previously available . reference number
