Description

The invention relates to a method and a control device for influencing a state of mind of an occupant of a motor vehicle and a motor vehicle with such a control device.

Even during a fully autonomous drive with a motor vehicle, an occupant of the motor vehicle should be able to actively take over control of the motor vehicle at any time. In order to be able to ensure that the occupant is actually awake and attentive at all times while the motor vehicle is traveling and is therefore able to take over the control of the motor vehicle, monitoring the occupant of the motor vehicle is particularly suitable. However, such monitoring is also useful in manually controlled motor vehicles, in order to be able to help the driver of the motor vehicle to feel particularly relaxed and stress-free in situations that are upsetting for many drivers, such as a traffic jam or heavy inner-city traffic, as a result of which he feels comfortable an optimal state of mind for driving the motor vehicle.

In addition to vehicle environment conditions, previously known camera systems can also detect a mood of the driver of a motor vehicle on the basis of its gestures and facial expressions in the visual field and of movements of the upper body, arms and hands. For example, a quick-tempered driver who gets stuck in a traffic jam on an expressway or dangerously approaches a vehicle that is relatively slow in front of him can be clearly identified by means of image analysis from front and interior cameras.

In the DE 10 2016 207 447 A1 describes a method and a device for passenger assistance in a vehicle. In this case, a sensor device detects a biosignal of the occupant, for example an eyelid frequency, movement on a seat or voice and facial expression signals, and a psychophysiological parameter is determined therefrom. A state value of the occupant is determined on the basis of the psychophysiological parameter. Which state value is to be assigned to which psychophysiological parameter is determined, for example, by means of a comparison with stored older parameters of the occupant. Depending on the determined condition value, the occupant receives predetermined employment recommendations when they are implemented, environmental conditions such as interior lighting or a sound system for the occupant with an entertainment system are adapted. In addition, read-in occupant-specific data from sources other than the vehicle, such as calendar entries or information from social networks, allow conclusions to be drawn about the preferences and interests of the occupants, so that in combination with monitoring the stress level, the tiredness and the emotional state of the occupant, an entertainment optimized for the occupant and information program can be compiled.

In the DE 101 52 852 A1 describes a system with which an emotional state of a driver of a motor vehicle can be determined and influenced. For this purpose, various emotion-related parameters are determined and, among other things, a driver's driving style, facial features or biophysical variables, such as a pulse or breathing frequency, are recorded. Based on these parameters and stored medical knowledge, the driver's emotional state is assessed and the driver is stimulated accordingly by optical, acoustic, olfactory, haptic and / or thermal influences. The type and intensity of the stimulating influences in the manner of a closed control loop, in which the driver's emotional state is permanently monitored and influenced by appropriate stimulation, is set by means of feedback from the sensors recording the parameters, in order to ultimately drive the driver into an emotional state that is favorable for traffic safety To put constitution.

In the DE 10 2011 109 564 A1 describes a method for monitoring a vehicle occupant in a vehicle. Vital parameter values of the vehicle occupant, such as their respiratory rate or skin temperature, are recorded and emotional states such as joy, stress or anger are determined based on them in addition to health risks. In addition, environmental parameters, such as a position of the vehicle, are recorded and a traffic situation is recognized on the basis of this, in order to be able to identify and assign possible deteriorations in the vital parameters due to a specific driving situation or vehicle environment. In this case, comparisons are also carried out with stored older vital parameter values and environmental parameter values, which enables short to long-term analyzes of the vital state of the vehicle occupant.

It is an object of the invention to provide a solution with which a mood detection of an occupant of a motor vehicle can be influenced in a particularly reliable manner.

This object is achieved by a method and a control device for influencing a mood detection of an occupant of a motor vehicle in accordance with the independent patent claims. Advantageous configurations with appropriate and Non-trivial developments of the invention are specified in the dependent claims.

The invention is based on the knowledge that the above-mentioned methods and devices do not differentiate that, with regard to the effectiveness of such a method or system, measures which are intended to positively influence a physical condition of the driver can only be particularly successful if one are personalized and secondly take into account a degree of emotional state, for example a degree of aggression or a degree of tiredness.

The method according to the invention for influencing a state of mind of an occupant of a motor vehicle comprises the following steps: identifying the occupant of the motor vehicle, detecting a behavior of the occupant in a current driving situation of the motor vehicle by means of a detection device, determining the current state of mind of the occupant based on the detected behavior, selecting one of the determined state of mind and the measure assigned to the current driving situation to influence the mood detection of the occupant on the basis of an occupant profile assigned to the identified occupant and activation of the selected measure by means of the motor vehicle device designed to influence sensory organs.

The method according to the invention is therefore designed to influence a mood, that is to say a state of mind, of an occupant of a motor vehicle, for example a driver of the motor vehicle. As part of the method, the occupant of the motor vehicle is first identified. This can be done, for example, with the aid of an interior camera of the motor vehicle, which can access a database of profile pictures of users of the motor vehicle and can identify the current occupant of the motor vehicle through a corresponding comparison with the stored user profile pictures. As an alternative or in addition to this, the identification of the occupant of the motor vehicle can be carried out, for example, using a personalized key or a key with a fingerprint sensor for uniquely identifying the occupant. In the motor vehicle, occupant profiles of several potential occupants can thus be stored, which are each intended to use the motor vehicle.

When the motor vehicle is in use, it is then observed and recorded on the basis of corresponding measurement data how the occupant behaves in the motor vehicle. The behavior of the occupant can be detected, for example, with the aid of the interior camera, which on the one hand captures gestures and facial expressions of the occupant, but can also capture an eye position, an eyelid beat frequency and a direction of gaze of the occupant. In addition, the behavior of the occupant, if this is the driver of the motor vehicle, can be based on data from evaluation units of various vehicle functions, such as an electronic vehicle control system which is designed to monitor an accelerator and / or brake pedal actuation, or an electronic one Steering, or a distance sensor can be detected. Furthermore, the current driving situation is recorded by means of the detection device, that is to say it is determined, for example, the type of road, the traffic situation and the time of day the motor vehicle is moved. The detection device therefore includes, for example, the aforementioned interior camera, evaluation units of various vehicle functions, exterior sensors, such as exterior cameras in the front, side and rear areas of the motor vehicle, radar devices, lidar devices or heat sensors, and optionally an evaluation unit of a data memory in the motor vehicle, which, for example, uses Maps, current traffic information or weather information.

Based on the detected behavior, for example on the basis of the detected gesture of the occupant, who is increasingly gesticulating with his hands above the area of the neck of the occupant due to an emerging traffic jam on the expressway, the current mood, i.e. the mood of the occupant, can be inferred , In this situation, the strong gestures of the occupant indicate an unbalanced state of mind and an incipient tantrum of the occupant. In general, different moods can be distinguished, such as the relaxed, slightly excited, hot-tempered, angry, stressed or tired moods.

The determined state of mind is also compared with the current driving situation. This procedural step is based on the idea that the state of mind of the occupant, depending on the current driving situation, that is, depending on whether the occupant is on the expressway with the motor vehicle or in an inner-city area, can make sense to take different measures to change his state of mind. Therefore, based on the determined state of mind and the recorded current driving situation, the measure is selected from a series of measures which, according to an occupant profile of the occupant, is suitable for influencing the mood of the occupant in a particularly advantageous manner in the determined state of mind and the recorded current traffic situation and is therefore suitable for achieving a desired state of mind. Since the occupant of the motor vehicle was uniquely identified at the start of the method, in this procedural step it is now possible to assign him precisely the measure which is suitable for his occupant profile in order to influence his state of mind as desired.

These measures are measures for influencing the sensory organs, that is to say they influence the hearing, seeing, feeling and / or smelling of the occupant. As soon as the measure assigned to the determined state of mind and the detected current driving situation is selected, it is activated and implemented with the aid of various devices in the motor vehicle. For example, the sensory organ "hearing" can be influenced by a selected multimedia program, for example by correspondingly controlling a radio or multimedia player. The sensory organ “seeing” can take place, for example, with the aid of a controllable device for adapting an ambient lighting in the interior of the motor vehicle and can reduce stress. In addition, for example with the help of comfort seat functions, such as a massage seat or an electric seat heater, or with the help of a vibrating steering wheel, the sensory organ "feeling" and with a fragrance spray sprayed in the vehicle, the sensory organ "smell" can be influenced. With the help of the fragrance spray, for example, a pleasant irritation of the sense of smell can take place, whereby the situation currently experienced can change its appearance in the subconscious of the occupant. By means of the devices designed to influence sensory organs, it is possible to influence the overall ambience in the motor vehicle.

An occupant of the motor vehicle identified on the basis of his behavior as angry may therefore have deposited the measure according to his occupant profile as a measure for influencing his state of mind, that is to say “angry” in this situation of the state of mind, that playing a calming meditation music has a positive effect on his state of mind. However, it can also be set that this meditation music is only played in the inner-city area if there are appropriate moods, but when driving on an expressway, for example, when his mood "angry" usually lasts significantly longer than in the inner-city area, in addition to playing the meditation music the ambient lighting in the motor vehicle is changed to its favorite color, for example green.

With the method according to the invention, it is thus possible for an occupant of the motor vehicle to activate an occupant profile, on the basis of which measures to influence his state of mind are taken depending on a determined state of mind and a detected current driving situation, in order to ultimately positively influence the determined state of mind of the occupant. On the one hand, this enables a personal influence on the state of mind of the occupant of the motor vehicle. This is particularly advantageous since personalized influences generally have a particularly positive effectiveness with regard to influencing the physical condition of the occupant. In addition, the distraction, relaxation method or occupation can be selected which can have a particularly reliable effect for the respective occupant and which is desired by the occupant. In addition, the corresponding measures are tailored to the current situation in which the occupant of the motor vehicle is located, so that the mood of the occupant is influenced in a particularly differentiated manner and taking into account the degree of the state of mind, which often depends on the current driving situation. This enables intelligent and automated support for mood fluctuations of a motor vehicle occupant, which differentiates between different levels of determined moods and is therefore suitable for easily excitable, unbalanced, irascible and tantrums, but also for bored and tired occupants of a motor vehicle. Ultimately, the overall ambience in an autonomously driving and in a manually controlled motor vehicle can be designed to be particularly calming and pleasant but nevertheless motivating for the occupant with regard to a possible active takeover of the control of the motor vehicle.

In a further advantageous embodiment of the invention, it is provided that a driving behavior and / or a physical behavior of the occupant is recorded as the behavior of the occupant by means of the detection device. The detection device thus not only detects the occupant's gestures and facial expressions, for example using an interior camera, but also or alternatively to his driving behavior. This driving behavior is reflected, for example, in the number of braking and acceleration signals in a certain period of time. For example, in the case of an occupant of the motor vehicle who brakes or accelerates several times within a minute, for example, it can be concluded that this occupant is particularly excited or controls the motor vehicle under a high level of stress. The driving behavior of the occupant may therefore contain a lot of information about how his current state of mind affects his driving behavior. This information is particularly suitable for taking the ideal measure depending on the degree of excitation detected To propose and implement improvements in his state of mind.

The braking and acceleration behavior of the occupant can be recorded, for example, using an evaluation device of an electrical control device of the motor vehicle, which brakes and accelerates the motor vehicle using brake-to-wire technology. Further possibilities for detecting the driving behavior are possible with the aid of a distance sensor which detects the distance to other vehicles driving in front of the motor vehicle, and the sensors of a lane change assistant with which lane changes can be identified. The detection of these parameters is also particularly suitable for assessing the current state of mind of the occupant of the motor vehicle, since frequent lane changes, in particular unauthorized lane changes to the right lane of an expressway for overtaking maneuvers, as well as dense collision with other vehicles driving in front of the motor vehicle generally indicate signs of severe damage are stressed and unbalanced inmates. On the basis of this detailed recording of the behavior of the occupant, a particularly differentiated determination of the current state of mind of the occupant is possible.

In addition, a time window, for example from a few seconds to a few minutes, can be predetermined for the detection of the physical behavior of the occupant before this behavior is used to infer a state of mind of the occupant. This ensures that emotions lasting only a very short time do not lead to measures being taken to influence the state of mind of the occupant, which may not be necessary and sensible in such a situation.

A further embodiment of the invention provides that, in order to detect the current driving situation, a traffic situation in which the motor vehicle is located is determined on the basis of a vehicle position and / or a vehicle environment detected by the detection device. Based on the detected current driving situation, information is therefore available as to whether the motor vehicle is in a traffic jam situation or is traveling freely on a road. In addition, with the aid of the detection of the vehicle environment, for example with the aid of the external sensors of the motor vehicle, it is detected, for example, whether the motor vehicle is in a dense traffic situation, is driving in the inner city area, is only stopping at a traffic light system or has been forced to stop by a traffic jam on an expressway. This sensor also detects how other road users are moving relative to the motor vehicle.

In addition, the exterior sensors can be used to detect, for example, whether a driver's driving behavior is influenced by other road users, such as other vehicles, cyclists or pedestrians. The current driving situation recorded in this way generally has a great influence on the state of mind of the occupant, but also on the possibilities of how this state of mind can be positively influenced. For example, it may be the case that the passenger of the motor vehicle, while stopping the motor vehicle due to a traffic jam situation on an expressway, gesticulates wildly and is upset about the situation, but tends to react more relaxed, despite a behavior pattern similar to that of a repeated stopping in front of red traffic lights in inner-city traffic. The measures that make sense to influence this excited state can therefore be very different. In the traffic jam situation on the expressway, for example, playing a favorite music stored can already significantly improve the mood of the occupant, whereas such acoustic sounding of the occupant in the inner city area may not be able to clearly compensate for the frustration with the many red traffic lights. In inner-city areas, it may make more sense to positively influence the mood of the occupant by means of an additional massage using a massage seat. The detection of the current driving situation thus serves to select the ideal measure for influencing the mood of the occupant, which is ultimately provided in the motor vehicle in a personalized manner using the occupant profile.

In a further embodiment of the invention, it is provided that, in order to determine the current mood detection of the occupant on the basis of the detected behavior, the detected behavior is compared with predefined behavior patterns, which are each assigned to a predefined mood detection. Various standard mood states are thus stored in the motor vehicle, which can be differentiated on the basis of the gestures and facial expressions of the occupant, his eyelid beat frequency, his motor movements in the vehicle seat, his cries, which can be detected, for example, by means of a microphone device, or other behavioral indicators. Ultimately, for example, ten different states of mind can be distinguished on the basis of the recorded behavioral patterns, each of which can be assigned to a predetermined range of measured values of behavioral measured values. It is also possible here that in the context of repeated recording of a behavior of the occupant and by means of the information in the occupant profile, the state of mind is more and more personalized when the method is used frequently and corresponds to the actual state of mind of the occupant. Ultimately, this is one Classification of the recorded behavior to the current state of mind is particularly quick and as differentiated as possible. In particular in autonomous driving, a wellness function can also be implemented, that is to say, for example, a state of mind can be defined and ascertainable, which is associated with a measure for increasing the well-being of the occupant. The measure designed to improve the well-being of the occupant can include, for example, a massage with the massage seat and simultaneous playing of the stored favorite music, a predetermined fragrance or a predetermined ambient lighting.

A further advantageous embodiment of the invention provides that a standard profile is provided as the occupant profile and the occupant is asked to create his or her personalized occupant profile based on the standard profile by assigning the desired moods to the desired measure, with this assigned measure a number of predetermined measures can be selected or determined individually. When the method is used for the first time, a standard profile can thus be selected by the occupant and activated as his occupant profile. However, the occupant is then asked to change this standard profile in such a way that the desired measures are stored in it. As a result, the occupant can select the music he wants, relaxation videos or films he wants, desired light colors for the lighting ambience of the interior, a strength of the massage through the massage seat or particularly stimulating scents and store them in his occupant profile. In order to make the creation of the personalized occupant profile particularly pleasant and quick to carry out, the occupant can select from a number of predefined measures, for example by merely specifying the source of the measures. For example, it can be specified that soothing music is played in the event of a slight tantrum. The corresponding settings menu is then linked to the media library of the motor vehicle, so that the occupant can particularly easily select a relaxation song list that he desires for this purpose. However, the measures can also be determined individually. For example, the occupant can store a light and lighting program that he has put together as a measure in the motor vehicle, which has a particularly encouraging or relaxing effect for him and should be activated when a desired state of mind is desired. This makes it possible for the occupant of the motor vehicle to always select the most convenient and sensible measure for influencing his state of mind and consequently to be activated in a corresponding situation. The creation of the occupant profile and generally the activation of the method is preferably voluntary and is actively selected by the occupant, for example when starting a journey with the motor vehicle by actuating a corresponding actuating element on a display area in the motor vehicle.

A further embodiment of the invention provides that after activating the selected measure, the occupant's behavior is checked again to determine whether the occupant's mood has been influenced by activating the selected measure and if the desired influencing has not occurred, one Additional measure is selected and activated on the basis of the occupant profile in order to additionally influence the mood detection of the occupant. So it is actively determined whether the selected and activated measure has actually brought the success that was intended with it. For this purpose, the behavior of the occupant is recorded again and his or her current, possibly changed mood is determined. Based on this second state of mind, which is now up-to-date, it is checked whether a desired influencing has already taken place. If, for example, an incipient tantrum of the occupant was detected due to a traffic jam situation on an expressway, the occupant's favorite music was played as a measure, as is intended according to the occupant profile. However, if it is subsequently determined that the occupant is still angry and unbalanced, which is determined when his behavior is recorded again, an additional measure can be taken to further calm him down. This additional measure can include, for example, that a predetermined fragrance is emitted in the motor vehicle. The reaction of the occupant to the measure and the effect of the measure on the condition of the occupant are registered and used so that, if necessary, in a kind of control loop, further measures can be taken to achieve a desired state of mind of the occupant.

In a further advantageous embodiment of the invention, it is provided that if it is determined during the check that the behavior of the occupant has been influenced but the desired influencing has not occurred, the measure is selected and activated as an additional measure, which is assigned to the state of mind according to the occupant profile that was determined based on the behavior that was recorded again. If, for example, it is determined that the measure taken has already improved the occupant's state of mind from “angry” to “slightly excited”, the measure can now be selected and activated that the “mildly excited” state of mind according to Occupant profile is assigned. This can, for example, cause a change in the music that is played in the motor vehicle or a change in the ambient lighting. It is thus possible that the influencing of the state of mind is always adapted to the current state of mind and thus the undesired excited or tired state of mind of the occupant is changed particularly quickly and with high probability to a desired relaxed and motivated state of mind.

A further embodiment of the invention provides that the effects of the selected measure on the state of mind of the occupant, ascertained during the review, are provided for a specification of the occupant profile. The results of the first, the second and, if appropriate, further additional detection processes of the behavior of the occupant can thus be used to dynamically and automatically adapt the occupant profile to the preferences of the user, who are not aware of this, for example, but when carrying out the method for influencing the mood of the occupant of the motor vehicle are determined, are taken into account. This always results in current and thus, for example, also reacting to a change of preference of the occupant occupant profiles, on the basis of which the particularly suitable measure for influencing the emotion detection of the occupant whose occupant profile is currently selected can always be selected. The occupant profile is thus learnable and automatically adaptable to observed changes, which means that it is continuously and automatically optimized when used repeatedly.

Another embodiment of the invention is that the specified current driving situation is also taken into account when specifying the occupant profile, in order to assign several measures specific to the driving situation to each state of mind. Depending on the current driving situation of the occupant, appropriate measures are taken. The determined state of mind "slightly excited" can therefore lead to different measures depending on whether it occurs in a traffic jam situation on an expressway, in a traffic jam situation in an inner city area, due to another vehicle overtaking or due to a bicycle riding in front of the motor vehicle. all of which are stored in the occupant profile. The degree of change in a state of mind can thus be particularly nuanced because it can be adapted to the current driving situation and influenced.

A further advantageous embodiment of the invention is that the measures for influencing the state of mind of the occupant comprise at least one of the following measures: varying a brightness and / or a color of an interior lighting of the motor vehicle, selecting a predefined multimedia program, activating a predefined massage program of a vehicle seat, giving off a given fragrance. By varying the brightness, the color scheme, the music and / or film program, the strength of the massage and the smell of the fragrance, all the senses of the occupant can be influenced, precisely in the type and strength of the occupant's current mood and mood current driving situation is desired.

According to the invention, a control device is also provided for carrying out a method for influencing a mood detection of an occupant of a motor vehicle, as described above. The preferred embodiments presented in connection with the method according to the invention and their advantages apply accordingly, if applicable, to the control device according to the invention.

According to the invention, a motor vehicle is also provided with the control device described above, that is to say the motor vehicle is designed to carry out the method described above for influencing the mood detection of an occupant of a motor vehicle. The preferred embodiments presented in connection with the method according to the invention and their advantages apply accordingly, if applicable, to the motor vehicle according to the invention.

The invention also includes combinations of the features of the described embodiments.

The invention also includes further developments of the method according to the invention which have features as have already been described in connection with the further developments of the motor vehicle according to the invention. For this reason, the corresponding developments of the method according to the invention are not described again here.

An exemplary embodiment of the invention is described below. For this purpose, the single figure shows a schematic representation of a motor vehicle with an excited occupant in a traffic jam situation on an expressway.

The exemplary embodiment explained below is a preferred embodiment of the invention. In the exemplary embodiment, the described components of the embodiments each represent individual, Features of the invention to be considered independently of one another, which further develop the invention independently of one another. Therefore, the disclosure is intended to include combinations of the features of the embodiment other than those shown. Furthermore, the described embodiment can also be supplemented by further features of the invention that have already been described.

In the figure, the same reference numerals designate elements with the same function.

In the single figure is a motor vehicle 10 outlines that in a traffic jam situation on a two-lane expressway 20 surrounded by numerous other vehicles 30 located. In this motor vehicle 10 an occupant sits 40 , which is, for example, a driver of the motor vehicle 10 or a user of the autonomously driving motor vehicle 10 can act. The car 10 comprises a detection device 50 which in turn is an indoor camera 51 as well as an outdoor camera 52 comprises, as well as a control device 60 , The car 10 also has various facilities 70 for influencing sensory organs. These facilities 70 include, for example, a vehicle seat 71 that can be used as a massage seat, a multimedia player 72 , such as a stereo system, as well as interior lighting 73 , Other possible facilities 70 of this type are, for example, a fragrance spraying device which has differently adjustable scents, a screen for displaying films or a vibrating steering wheel. The control of the various facilities 70 for influencing sensory organs and the evaluation of the detection device 50 Measured data are recorded using the control device 60 ,

When starting the motor vehicle 10 became the inmate 40 by matching one with the indoor camera 51 recorded shot of his face with one in the motor vehicle 10 stored profile picture identified. For the occupant identified in this way 40 is in the motor vehicle 10 in the control device 60 an occupant profile stored in the preferences of the occupant 40 for different moods of the occupant 40 are deposited. In the case of the occupant 40 For example, three states of mind are specified, namely the "slightly agitated", "angry / angry" and "tired". The inmate 40 has "slightly excited" the measure in the state of mind that he wishes to play a relaxation music list selected by him. The occupant has this relaxation music list 40 based on one in a multimedia device of the motor vehicle 10 saved music collection. In the occupant profile of the occupant 40 the "massage" measure is also stored in the state of mind "angry / angry". This massage can be done using the vehicle seat 71 be carried out and has also been specified in the occupant profile in terms of a strength of the massage. The inmate “tired” of the state of mind 40 For example, the measure assigned that predetermined ambient lighting by means of the interior lighting 73 activated and an animating motivational music list with the multimedia player 72 is played. The predetermined ambient lighting can, for example, make settings relating to a brightness, a color tone or possibly a flashing frequency of in the motor vehicle 10 arranged lighting elements include.

With the help of the detection device 50 is in the motor vehicle 10 a behavior of the occupant 40 detected. This behavior includes both a driving behavior of the occupant 40 and, additionally or alternatively, physical behavior of the occupant 40 , In addition to the detection of, for example, gestures and facial expressions, an eyelid beat frequency and a direction of view of the occupant 40 using the interior camera 51 can thus also, for example, a braking and acceleration behavior of the occupant 40 based on corresponding data from a control device based on brake-by-wire technology, a distance from the others, the motor vehicle 10 surrounding vehicles 30 or a frequency of lane changes are recorded. In addition, appropriate sensors can be used to determine the physical behavior of the occupant 40 descriptive parameters or exclamations and spoken language of the occupant 40 be recorded.

In addition to capturing the behavior of the occupant 40 becomes a current driving situation of the motor vehicle 10 detected. This can be done using the external camera, for example 52 take place, the current traffic situation in which the motor vehicle 10 located, recorded. This can be used, for example, to determine whether the motor vehicle is 10 , as outlined in the figure, in a traffic jam situation on the expressway 20 or whether it is moving in heavy city traffic, is repeatedly forced to stop in front of traffic lights or by other vehicles 30 possibly negatively influenced in its driving, for example by a vehicle overtaking from the right 30 (not sketched in the figure). As part of the detection of the current driving situation, it is a current vehicle position and / or with the detection device 50 determined a vehicle environment.

Once the behavior of the occupant 40 was recorded, the current state of mind of the occupant is based on this behavior 40 determined. For this, the recorded behavior is included predefined behavioral patterns in the control device 60 are stored, compared, each of these behavior patterns being assigned to a given state of mind. Based on the detected behavior of the occupant 40 can thus be assigned to one of the three moods stored in the occupant profile, namely the moods "slightly excited", "angry / angry" or "tired". The settings of this occupant profile are preferably personalized, i.e. they were based on a standard profile that the occupant 40 initially in the motor vehicle 10 provided by the occupant 40 the predefined states of mind, that is, in this situation the three states of mind "slightly agitated", "angry / angry" and "tired", each assigned the measures desired by him and already mentioned above. The occupant can take these assigned measures 40 select from a number of specified measures and / or determine them individually.

After the current state of mind of the occupant 40 an operating measure is selected which, taking into account the detected driving situation, is suitable for the mood of the occupant 40 beneficial to influence. The measure is therefore taken from the occupant profile, in which measures are assigned to the various states of mind. It is also possible that not only one measure is assigned to one state of mind in the occupant profile, but several. For example, the measure for the state of mind "slightly excited" can be selected depending on the current driving situation detected. Becomes the occupant 40 in a traffic jam on the expressway 20 slightly excited, the relaxation music list he wants can be played. Will a slight excitement of the occupant 40 however observed in rush hour inner-city traffic, i.e. at predetermined times in the morning and afternoon and in particularly heavy inner-city traffic, in addition to the relaxation music list, you can set the desired ambient lighting, for example a color change choreography between orange and green light.

The inmate 40 of the motor vehicle 10 is in the traffic jam situation, for example, in a slightly excited state of mind, which is due to the gesticulating hands 41 of the occupant 40 using the interior camera 51 be detected, is detected. Using the outside camera 52 it is also found that the current driving situation of the motor vehicle 10 a traffic jam situation on the expressway 20 represents. According to the occupant profile of the occupant 40 this leads to the measure being taken by the occupant 40 desired relaxation music list using the multimedia player 72 is played.

If the occupant were 40 in his motor vehicle 10 instead of the congestion situation in the situation that the motor vehicle 10 with very little traffic, in the dark on a straight expressway 20 drives and due to the eyelid beat frequency with the indoor camera 51 a beginning fatigue of the occupant is detected 40 would be found, the occupant 40 the state of mind is assigned to "tired" and accordingly another measure to influence the state of mind of the occupant 40 to get voted. In the state of mind above all the occupants are "tired" 40 motivating and animating measures make sense. The occupant profile therefore includes particularly pleasant ambient lighting using the interior lighting 73 as well as playing an animating motivational music list with the multimedia player 72 from the occupant 40 deposited as a measure. As ambient lighting using interior lighting 73 is suitable in this situation, for example, for revitalizing the occupant repeatedly flashing red light, i.e. a flashlight interval switching in red tones.

After the selected measure has been activated, the behavior of the occupant is recorded again 40 using the detection device 50 , It is checked whether the activation of the selected measure actually influences the mood of the occupant 40 is done. With the slightly excited occupant 40 in the traffic jam situation on the expressway 20 this would be, for example, that no more conspicuous state of mind is determined, that is, playing the relaxation music list to actually relax the occupant 40 has led. If, however, the desired influence on the state of mind has not occurred, for example the occupant 40 still in a slightly excited state of mind in the motor vehicle 10 sits, an additional measure can be taken, which is also selected based on the occupant profile and thereby also the mood of the occupant 40 being affected.

This additional measure can be, for example, the measure that is taken when the occupant's behavior is recorded again 40 determined mood is assigned. Was the inmate 40 for example, initially in the state of mind “angry / angry” and became activating the massage with the vehicle seat 71 activated, whereby his state of mind was only "slightly aroused" to the state of mind, is now, according to the occupant profile, in addition to the massage Relaxation music list played. It is also possible that the massage is ended and only the relaxation music list is played. The activated measure is therefore always the current behavior of the occupant 40 and the current state of mind of the occupant determined thereby 40 customized.

Generally, the impact is felt every time the occupant's behavior is detected 40 as well as the current state of mind determined from it can be used to further specify the occupant profile. This makes it possible that despite the initially relatively general measure settings in the occupant profile after repeated use and application of the method, an increasingly differentiated catalog of measures, depending on the current driving situation and reacting to the actual effects of the desired measures on the occupants 40 , and thus a particularly differentiated and personalized occupant profile is generated.

Overall, the example shows how using the control device 60 a method for influencing the mood of the occupant 40 of the motor vehicle 10 can be carried out. The behavior of the occupant becomes part of the procedure 40 as well as the current driving situation of the motor vehicle 10 taken into account, ultimately, based on personalized, by the occupant 40 desired and provided measures that affect the sensory organs of the occupant 40 influence to influence his state of mind in such a way that the occupant 40 can enjoy a particularly pleasant and motivating driving experience.
