Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur Erkennung von Emotionszuständen und deren zeitliche Veränderungen und Zusammenhänge der Veränderungen der Emotionszustände von Insassen eines Fahrzeuges anzugeben, bei welchen die beschriebene Lösung verbessert wird.The object of the invention is to specify a method and a device for recognizing emotional states and their temporal changes and relationships between the changes in the emotional states of vehicle occupants, in which the described solution is improved.
Die Erfindung ergibt sich aus den Merkmalen der unabhängigen Ansprüche. Vorteilhafte Weiterbildungen und Ausgestaltungen sind Gegenstand der abhängigen Ansprüche. Weitere Merkmale, Anwendungsmöglichkeiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, sowie der Erläuterung von Ausführungsbeispielen der Erfindung, die in den Figuren dargestellt sind.The invention results from the features of the independent claims. Advantageous further developments and refinements are the subject matter of the dependent claims. Further features, possible applications and advantages of the invention emerge from the following description and the explanation of exemplary embodiments of the invention which are shown in the figures.
Die Aufgabe wird mit dem Gegenstand des Patentanspruchs 1 gelöst.The object is achieved with the subject matter of
Bei dem eingangs erläuterten Verfahren werden Aktivitäten von mehreren Fahrzeuginsassen im Fahrzeuginnenraum erfasst und die über den vorgegebenen Zeitraum bestimmten Emotionsverläufe der einzelnen Insassen mit sensorisch erfassten Veränderungen im Fahrzeuginnenraum den einzelnen Fahrzeuginsassen zugeordnet. Dies hat den Vorteil, dass die Interaktion zwischen den Fahrzeuginsassen verbessert wird und damit eine Steigerung des Wohlbefindens der Fahrzeuginsassen erzielt wird.In the method explained at the outset, activities of several vehicle occupants in the vehicle interior are recorded and the emotion processes of the individual occupants determined over the specified period of time with sensor-recorded changes in the vehicle interior are assigned to the individual vehicle occupants. This has the advantage that the interaction between the vehicle occupants is improved and thus an increase in the well-being of the vehicle occupants is achieved.
Vorteilafterweise werden die Emotionsverläufe zusammen mit den sensorisch erfassten Veränderungen mittels statistischer Verfahren und/oder Methoden des maschinellen Lernens anonymisiert ermittelt und die anonymisierten Daten den Fahrzeuginsassen zugeordnet. Die verwendeten Auswerteverfahren erlauben eine zuverlässige Zuordnung der ermittelten Emotionsverläufe auf den jeweiligen Fahrzeuginsassen. Durch die Anonymisierung der ermittelten Daten wird gleichzeitig dem Datenschutz Rechnung getragen.Advantageously, the emotion profiles together with the changes recorded by sensors are determined anonymously by means of statistical methods and / or methods of machine learning and the anonymized data are assigned to the vehicle occupants. The evaluation methods used allow a reliable assignment of the determined emotion profiles to the respective vehicle occupants. By anonymizing the data obtained, data protection is also taken into account.
In einer Ausgestaltung werden mittels der in dem vorgegebenen Zeitraum ermittelten Emotionsverläufe Wechselbeziehungen zwischen den Fahrzeuginsassen und deren Ursache und/oder Abhängigkeit bestimmt. Auf Grund der Ursachenerkennung kann gezielt auf eine Verbesserung des Wohlbefindens der Fahrzeuginsassen hingewirkt werden.In one embodiment, interrelationships between the vehicle occupants and their cause and / or dependency are determined by means of the emotion profiles ascertained in the predetermined period of time. On the basis of the identification of the cause, it is possible to work towards improving the well-being of the vehicle occupants in a targeted manner.
In einer Variante werden anhand der erkannten Wechselbeziehungen zwischen den Fahrzeuginsassen fahrzeuginterne und/oder fahrzeugexterne Applikationen angepasst. Durch die automatischen Änderungen von Fahrzeugapplikationen lässt sich das Wohlbefinden der Fahrzeuginsassen besonders einfach erhöhen.In one variant, on the basis of the identified interrelationships between the vehicle occupants, vehicle-internal and / or vehicle-external applications are adapted. Automatic changes to vehicle applications make it particularly easy to increase the well-being of the vehicle occupants.
In einer Ausführungsform werden die Fahrzeuginsassen über die erkannten Wechselbeziehungen informiert. Die Fahrzeuginsassen wissen nun, das eine automatische Anpassung der Fahrzeugeigenschaften zur Verbesserung ihres Wohlbefindens zeitnah erfolgen wird, so dass deren manuelles Eingreifen nicht notwendig ist.In one embodiment, the vehicle occupants are informed of the identified interrelationships. The vehicle occupants now know that the vehicle properties will be automatically adapted to improve their wellbeing in a timely manner, so that manual intervention is not necessary.
Ein weiterer Aspekt der Erfindung betrifft eine Vorrichtung zur Erkennung von Emotionszuständen von Insassen eines Fahrzeuges, umfassend eine Steuereinheit, welche mit einem Emotionserkennungsmodul zur Erfassung des aktuellen emotionalen Zustands mindestens eines Fahrzeuginsassen zu vorgegebenen Zeitpunkten verbunden ist, wozu das Emotionserkennungsmodul mit auf die Fahrzeuginsassen gerichteten akustischen und/oder optischen und/oder haptischen Sensoren gekoppelt ist. Bei einer Vorrichtung ist zur Verbesserung des Wohlbefindens der Fahrzeuginsassen ein Aktivitätserkennungsmodul zur Erfassung einer körperlichen Aktion der Fahrzeuginsassen auf die Steuereinheit zur Bestimmung zeitlich abhängiger Emotionszustände der einzelnen Fahrzeuginsassen und deren Wechselbeziehungen geführt.Another aspect of the invention relates to a device for recognizing emotional states of occupants of a vehicle, comprising a control unit which is connected to an emotion recognition module for detecting the current emotional state of at least one vehicle occupant at predetermined times / or optical and / or haptic sensors is coupled. In one device, to improve the well-being of the vehicle occupants, an activity detection module for detecting a physical action by the vehicle occupants is routed to the control unit to determine time-dependent emotional states of the individual vehicle occupants and their interrelationships.
Es ist von Vorteil, wenn die Steuereinheit weitere Signale von einer zentralen Fahrzeugsteuereinheit zum Abgleich der Änderungen der ermittelten Emotionszustände mit allgemeinen Fahrzeugfunktionen und deren Änderungen empfängt. Somit können die ermittelten Emotionszustände den aktuellen Fahrzeugfunktionen zugeordnet werden, woraus eine Analyse möglich ist, welche Fahrzeugfunktionen zu welchen Emotionszuständen der einzelnen Fahrzeuginsassen führen.It is advantageous if the control unit receives further signals from a central vehicle control unit to compare the changes in the determined emotional states with general vehicle functions and their changes. Thus, the determined emotional states can correspond to the current one Vehicle functions are assigned, from which an analysis is possible, which vehicle functions lead to which emotional states of the individual vehicle occupants.
In einer weiteren Ausgestaltung ist eine Speichereinheit zur zentralen Speicherung der anonymisierten Emotionsverläufe der Fahrzeuginsassen Bestandteil der Steuereinheit oder fahrzeugextern positioniert und drahtlos mit der Steuereinheit verbunden. Damit wird sichergestellt, dass einmal gewonnene Informationen zur Einstellung der Fahrzeugfunktionen bei weiteren Fahrten der Fahrzeuginsassen abgerufen werden können.In a further embodiment, a memory unit for the central storage of the anonymized emotion profiles of the vehicle occupants is part of the control unit or positioned outside the vehicle and connected wirelessly to the control unit. This ensures that information once obtained for setting the vehicle functions can be called up by the vehicle occupants during further journeys.
