Description

The invention relates to a method for assessing motion sickness in at least one passenger of a vehicle while the vehicle is moving, the passenger being captured with a camera system of the vehicle and an assessment of whether the passenger is suffering from motion sickness as a function of the captured information.

The invention also relates to an electronic travel sickness assessment system with an evaluation unit and a camera system.

When traveling in motor vehicles, a passenger and other passengers in the second row of seats often suffer from motion sickness (kinetosis). In particular, travel or motion sickness occurs when unusual movements, for example in a means of transport or a skyscraper, are triggered without adequate vibration damping. A well-known variant of motion sickness is seasickness. For example, passive movements in coaches, cars, trains, airplanes, roller coasters can cause symptoms of motion sickness.

With the increasing degree of automation of vehicles, the driver (vehicle driver in automated driving mode) also becomes a passenger and can devote himself to secondary tasks such as reading or watching a film. Normally, the driver himself is usually not affected by motion sickness if he is actively driving himself. It is known that these secondary activities, in which the view is directed into the vehicle interior and thus the anticipation of the vehicle movement is no longer possible, can lead to symptoms of malaise, nausea and vomiting. As a result, side tasks are no longer performed by those prone to such symptoms of motion sickness. As a result, one of the added value of an automated vehicle, the effective use of the usual time in which the vehicle drives automatically, is significantly lower and customer acceptance of this automated driving technology could decrease.

The takeover scenario represents a further problem; it is known that kinetosis has negative effects on the reaction time of a person, which are elementary for the safe driving of a vehicle. Assuming that a vehicle driver can devote himself to a secondary activity in the automated driving mode, which makes him uncomfortable and / or nauseous, the vehicle takeover is a particular challenge occur at short notice. If the driver of the vehicle suffers from symptoms of kinetosis that limit the ability to drive, this not only poses a risk for himself, but also for his passengers, as well as for other road users. These are always dependent on the vehicle driver being able to take control of the vehicle at all times.

the DE 10 2015 011 708 A1 discloses a method for reducing kinetosis-related disturbances to an occupant in a vehicle. An individual tendency of the occupant to kinetosis is recorded by means of a manual input, with at least vehicle parameters, health parameters of the occupant and / or parameters relating to the route being recorded in order to determine the occurrence of kinetosis-related disorders.

the DE 10 2017 008 280 A1 discloses a vehicle seat. An occupant support that is suitable for use in a vehicle has a sensor system and a control system. The sensor system is designed to generate signals that indicate at least one of the occupant's physiological properties.

One object of the present invention is therefore to be able to precisely assess a health status of a passenger in a vehicle at any point in time in order to be able to initiate countermeasures at an early stage.

This object is achieved by a method and an electronic travel sickness assessment system according to the independent patent claims. Meaningful further developments result from the subclaims.

One aspect of the invention relates to a method for assessing motion sickness in at least one passenger in a vehicle while the vehicle is moving, the passenger being captured with a camera system of the vehicle and, depending on the captured information, it is assessed whether the motion sickness is a passenger occurs. With the camera system, information content, which is displayed on a medium unit in the vehicle observed by the passenger, is recorded and transmitted to an evaluation unit. Travel sickness is assessed depending on the information content recorded.

With the proposed method, a travel sickness can be better assessed and evaluated, so that the passenger can be better protected against the travel sickness. In particular, the proposed method enables a more effective assessment of travel sickness ( Kinetosis) can be carried out during a locomotion. By evaluating the information content, that is, what is currently displayed on the medium unit, a current assessment of the motion sickness can be made depending on the situation. In this way, the passenger can be monitored precisely during the entire journey and a current course of travel sickness can be assessed. In this way, the passenger can be protected against the occurrence of a possible motion sickness at an early stage, for example. Likewise, if travel sickness has already occurred, the passenger can be informed that countermeasures must be taken in order to minimize or alleviate the course of travel sickness.

Depending on the diverse and different information content that can be or are displayed on the medium unit, there are different influences on the passenger with regard to motion sickness. As a result, it is particularly advantageous to determine the occurrence of motion sickness and / or the current state of motion sickness in the passenger on the basis of this information and thus influencing factors. The information content can be, for example, the content of the information and / or the volume of the information and / or the action of the information.

In particular, actions can be provided to the passenger with the aid of the assessed travel sickness on the basis of the information content, so that an already occurring travel sickness or already prevailing kinetosis symptoms can be reduced. In particular, by evaluating the information content, the passenger can be advised of possible symptoms of travel sickness at an early stage.

For example, the at least one passenger can be a front passenger or a person in the back seat or the driver. In particular, any passengers within the vehicle can be monitored with the aid of the proposed method and travel sickness can be assessed in each case.

The assessment of motion sickness is particularly advantageous when it is a question of at least partially autonomous travel with an autonomously operable vehicle. As a result, the vehicle driver in particular can be monitored with the aid of the camera system. In this case, in the case of an at least partially autonomous locomotion, the vehicle driver can be given the command for the locomotion of the vehicle at any time. With the help of the assessed motion sickness, it can be achieved that the vehicle driver is able to take control of the vehicle at any time.

In particular, the method can be used in a vehicle or in an aircraft or in a watercraft or in a land vehicle or in an airplane or train or in a bus. In particular, the motion sickness can occur during any kind of travel with a means of locomotion.

The medium unit can be, for example, a smartphone or a tablet or a video game console or a magazine or a book or a laptop or a notebook or an e-book reader. The information content of the medium unit is, for example, text or images or video sequences or comics or caricatures or video games or puzzles or image sequences. The examples just mentioned for the medium unit and the information content are not to be understood as conclusive, but are only intended to provide a sub-range of possible application scenarios. Further examples are possible.

For example, a video game can be played on the medium unit by the passenger. A very action-packed video game (racing game) is more likely to suffer from motion sickness or symptoms than when reading a magazine.

For example, the camera system can have several cameras which are arranged in the interior of the vehicle. The evaluation unit can be, for example, a central unit in the vehicle or an external server or a data cloud. For example, an electronic travel sickness assessment system can be used in judging travel sickness.

In an advantageous embodiment of the invention it is further provided that the information content of the medium unit is categorized with the evaluation unit so that from the information content of the medium unit a predetermined level of a level model with at least two different levels of a disease course of travel sickness is assigned, with depending on the level the motion sickness is assessed. By categorizing the information content, for each current information content that is presented to the passenger on the medium unit, an exact and precise classification of the information content relating to a certain status of travel sickness can be made. Thus, the most varied of symptoms and / or Travel sickness forecasts are assigned to a respective information content. For example, the categorized information content can be transmitted and stored in a database of the evaluation unit. In particular, the categorization takes place with the aid of the evaluation unit, which is part of a vehicle system or is designed as an external server.

In particular, the categorized information content of the medium unit can be clearly assigned to a predetermined level. In particular, different stages or disease states can be assigned to a specific information content. As a result, depending on the evaluation of the information content, the evaluated information content can be continuously assigned to exactly one level of the step model. In particular, several stages or stages of the disease progression of the travel sickness are assigned with the stage model. Depending on the level assigned to the information content, a more effective and more precise assessment of the motion sickness can be carried out.

It is preferably provided that the at least two stages of the stage model are used to characterize a symptom severity and / or a temporal course and / or a duration of illness and / or a severity and / or an illness prognosis and / or an acuteness of the motion sickness. Thus, with the help of the stages of the stage model, a detailed prediction of a possible motion sickness can be carried out. In particular, by assigning a level to a temporal course of travel sickness, the passenger can be informed of the point in time from which the travel sickness would have a negative impact on the passenger. In this way, the passenger can be protected from serious travel sickness at an early stage. The level can also be used to take account of the acuteness of travel sickness when assessing travel sickness, so that at a high level or a high degree of acuteness, immediate and immediate measures or countermeasures can be initiated so that the passenger can be effectively protected against travel sickness.

In a further advantageous embodiment of the invention it is provided that if the information content of the medium unit cannot be recorded, the non-recorded information content is assigned to a special category, with the passenger depending on the assigned special category after a predetermined period of time on the likely occurrence of travel sickness is pointed out, and / or the camera system is machine-trained on the basis of the non-recorded information content. In this way it can be achieved that the passenger is in any case protected and informed as best as possible from a possible and / or already occurring motion sickness. Even if the information content could not be evaluated, the passenger can be informed or warned of a possible motion sickness using standard settings and / or default settings. Thus, the passenger can warn of a possible or already existing motion sickness at any time and regardless of the activity of the passenger during the journey. For example, the special category can be based on predefined basic settings and / or basic parameters. A predefined time threshold or duration can be specified. This period of time can be, for example, an average mean value within which motion sickness has not occurred or at least no severe symptoms are present. As a result, the passenger can still be protected from possible motion sickness despite the non-detectable information content.

For example, the camera system can be designed with a machine learning unit. With the aid of the machine learning unit, machine training of the camera system can be carried out. In particular, training is carried out with the aid of the machine learning unit of the camera system as a function of the non-detectable information content of the medium unit. Independent and continuous learning of the camera system can thus be achieved. In this way, information content presented in the future can be better captured by the camera system during future journeys. In this way, a more efficient and better and, in particular, less error-prone assessment of travel sickness can be made as a function of the information content.

In particular, the machine training of the camera system can be carried out with a “deep learning algorithm”.

Provision is also preferably made that, depending on the assessment of the travel sickness, a recommendation for action and / or a warning function and / or a warning and / or a countermeasure is provided to the passenger so that the passenger's travel sickness can be alleviated and / or the travel sickness can be prevented . As a result, various actions and recommendations for action can be made available to the passenger, with which the occurrence of kinetosis symptoms of motion sickness can be prevented in advance or at least to minimize the kinetosis symptoms. By providing the recommended action and / or the advisory information and / or the warning and / or the countermeasures, the passenger can be supported during the journey with the vehicle in such a way that a motion sickness that has already occurred is minimized or an impending motion sickness can even be prevented. In particular, this takes place without the passenger having dealt with the issue of motion sickness. The various pieces of information can be used to provide the passenger with precise procedures and instructions for reducing motion sickness. In particular, an essential action to reduce motion sickness is to direct the passenger's gaze upwards and to look in the longitudinal direction of the vehicle in order to be able to follow the course of the road while traveling. As a result, the passenger can be protected from symptoms of motion sickness at an early stage.

In an advantageous embodiment of the invention it is provided that the recommendation for action and / or the advisory information and / or the warning and / or the countermeasure is output to the passenger acoustically and / or optically and / or haptically and / or olfactorily with an output unit, in particular being output Output an optical light pattern with a light device in the interior of the vehicle so that the passenger is made aware of the assessed travel sickness. The output in a wide variety of output options can ensure that the passenger is always adequately informed and, in particular, is attentive and advised of the travel sickness assessed. The passenger can be made aware of motion sickness in the simplest and most effective way through the various output options. The information output about the assessed motion sickness can ensure that the passenger brings his posture and in particular his line of sight into a normal healthy position. In particular, the passenger should look outwards into the area around the vehicle.

For example, the output unit can be an instrument cluster or an infotainment system or a loudspeaker system and / or a display unit or a source of smell or a fan. With the aid of the output unit, the instructions that counteract motion sickness can be effectively output and made available to the passenger. In particular, several different types of output can also be used simultaneously with the output unit. This means that the passenger can be made aware of the motion sickness in the best possible way. In particular, several types of output can be used at the same time when the symptoms of motion sickness are at a high level and the acuteness of the motion sickness is very high. This means that the passenger can be notified of the motion sickness as quickly as possible and appropriate countermeasures can be initiated.

For example, the recommended action and / or the advisory information and / or the warning and / or the countermeasure can be output acoustically and / or optically with the aid of an instrument cluster as an output unit. The passenger can be advised to pause the current secondary task or activity with the medium unit and to look outside in the direction of travel. Furthermore, with the aid of the light device, an optical light pattern or an optical light signal can be output in the interior of the vehicle. For example, the light device can be a light band or various light sources. These can be arranged differently distributed in the vehicle interior of the vehicle. For example, the light device can be used to generate a wave-like movement upwards from the footwell of the interior of the vehicle. This wave-like movement is visualized in particular with the aid of the optical light pattern. As a result, the passenger can visually perceive that he should no longer look at the information content on the medium unit and should look outwards in the direction of travel.

For example, with the aid of loudspeakers as an output unit, an acoustic signal can be sent from the roof lining of the vehicle interior in the direction of the passenger. Another possibility is the signaling of the passenger about the assessed travel sickness with the help of an emitted odor. The smell can be sprayed into the vehicle interior with the help of fans, for example. The passenger can thus immediately perceive via his sense of smell that he should direct his gaze upwards.

In a further advantageous embodiment of the invention it is provided that a pronunciation and / or a breathing noise and / or a body temperature and / or a physiological property of the passenger is recorded in a recording device and is additionally taken into account when assessing the motion sickness. As a result, in addition to taking into account the recorded information and the evaluated information content, additional factors can be taken into account when assessing travel sickness. This means that motion sickness can be assessed and assessed in more detail and more precisely. In particular, with the aid of the recorded pronunciation and / or the breathing noise and / or the body temperature and / or the physiological property of the passenger, a precise analysis and evaluation of the current Health status of the passenger can be carried out during the journey with the vehicle. Thus, the safety of the passenger with regard to his state of health can be increased significantly.

As a result of these additionally recorded properties of the passenger, countermeasures to reduce the kinetosis symptoms of motion sickness can be carried out immediately upon detection of symptoms occurring in the passenger. In this way, the course and / or severity of the motion sickness can be reduced at an early stage. In this way, any motion sickness that occurs can be countered at an early stage.

For example, the pronunciation of the passenger or a breathing noise can be recorded with the aid of microphones and / or speech dialogue systems (SDS) inside the vehicle interior of the vehicle. For example, in the case of a clearly louder breathing noise and / or rapid breathing processes and / or gasping for breath, symptoms of motion sickness can be inferred.

The physiological properties mean, for example, a pulse or skin conductivity. Like body temperature, these can be determined using various measuring devices. For example, a smartwatch can be used for this. The body temperature can be determined with the help of infrared sensors in the vehicle interior. It is also conceivable that these physiological properties of the passenger are compared with the information recorded by the camera system. In this way, possible kinetosis symptoms of motion sickness can be inferred early and more quickly and countermeasures can be initiated as quickly as possible.

In a further advantageous embodiment of the invention it is provided that the passenger is recorded with at least two further, differently positioned cameras of the camera system, in particular continuously, during the journey, a body posture and / or a head position and / or with a first camera of the camera system a direction of view of the passenger is recorded and a type of medium unit is recorded with a second camera of the camera system, this recorded information being additionally taken into account when assessing the motion sickness. Furthermore, the information content of the medium unit can be recorded with a third camera of the camera system. By using differently positioned cameras, the camera system can more effectively capture the information relating to the passenger. By using the multiple cameras, the passenger can be observed and recorded in a more detailed and multi-faceted manner from the most varied of viewing directions. Thus, the passenger can be recorded in the best possible way for every position and / or activity of the passenger. Thus, a more accurate and precise judgment of the motion sickness can be made. In particular, the cameras of the camera system can be positioned in such a way that every passenger in the interior of the vehicle can be detected while the vehicle is moving.

In particular, the cameras can be focused on the driver of the vehicle.

In particular, each camera of the camera system fulfills special tasks. With the first camera, the posture and in particular the head of the passenger are precisely monitored and thereby recorded. In particular, the medium unit (smartphone or book) used by the passenger is recorded with the second camera. In particular, the information content of the medium unit can be recorded with the third camera. In this way, every essential piece of information for assessing travel sickness can be specifically recorded and, in particular, recorded and evaluated separately. In this way, special properties can be viewed and recorded in a focused manner, if necessary. Thus, a more precise and accurate assessment of the passenger's motion sickness can be carried out.

In a further advantageous embodiment of the invention, it is provided that the passenger is continuously recorded with a portable communication terminal of the passenger during the journey, with the portable communication terminal being used to display additional information content for the passenger, depending on the captured passenger and the additional information content Motion sickness is assessed. In particular, the passenger is recorded with the aid of a camera, in particular a front camera, of the portable communication terminal. The communication terminal is in particular a smartphone or a tablet or a mobile phone.

The detection of the passenger with the portable communication terminal advantageously occurs when the locomotion is carried out with a ship or a bus or a train or an airplane. It is also conceivable that if the camera system fails, the portable communication terminal is used as an alternative for capturing the passenger.

For example, the portable communication terminal can use information stored in the portable communication terminal or the determination of a GPS position to determine what type of travel is currently involved acts. In particular, the passenger's surroundings can be recorded very precisely with the aid of a front camera or a rear camera of the portable communication terminal.

In particular, it can furthermore be that the portable communication terminal is used as a medium unit in order to output the further information content to the passenger. In this case, the portable communication terminal already independently knows the information content displayed and can therefore assess it in the best possible way for possible symptoms of motion sickness. In particular, the recommended action and / or the advisory information and / or the warning and / or the countermeasure can be output to the passenger acoustically and / or optically and / or haptically with the aid of an output unit of the portable communication terminal.

Thus, with the aid of the portable communication terminal, the assessment of the motion sickness can be carried out independently of the type of means of locomotion for the locomotion trip. In particular, the portable communication terminal can be used to provide an alternative for assessing motion sickness if the camera system fails.

Another aspect of the invention relates to an electronic travel sickness assessment system with an evaluation unit and a camera system, the electronic travel sickness assessment system being designed to carry out a method according to one of the previously described aspects or a development thereof. In particular, the method described above is carried out with the electronic travel sickness assessment system. The electronic travel sickness assessment system can be, for example, an electronic unit in a vehicle or an external service provider or a data cloud or a server application. The electronic travel sickness assessment system can also be integrated in a portable communication terminal.

The invention also includes further developments of the electronic travel sickness assessment system according to the invention which have features as they have already been described in connection with the further developments of the method according to the invention. For this reason, the corresponding developments of the electronic travel sickness assessment system according to the invention are not described again here.

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

Exemplary embodiments of the invention are described below. This shows:

• 1 an embodiment for assessing a motion sickness during a locomotion;
• 2 a schematic arrangement of cameras of a camera system in the vehicle; and
• 3 a schematic arrangement of units for warning a passenger of motion sickness.

The exemplary embodiment explained below is a preferred embodiment of the invention. In the exemplary embodiment, the described components of the embodiment each represent individual features of the invention that are to be considered independently of one another, which also develop the invention independently of one another and are therefore also to be regarded as part of the invention individually or in a combination other than the one shown. Furthermore, the described embodiment can also be supplemented by further features of the invention that have already been described.

In the figures, functionally identical elements are each provided with the same reference symbols.

the 1 shows a vehicle, for example 1 , which is during a locomotion. In particular, the travel journey is a real journey, for example in road traffic. When the vehicle is moving 1 is at least one passenger 2 on board.

In particular, the locomotion can be done with a vehicle 1 or a land vehicle or an aircraft or a watercraft. With the vehicle 1 it can also be a motor vehicle or a bus or a truck or a ship or a bus or an airplane or a ferry.

With an electronic travel sickness assessment system 3 can be a possible occurring or already occurring motion sickness of the at least one passenger 2 in the vehicle 1 with the movement of the vehicle 1 be assessed. Travel sickness is, in particular, motion sickness or motion sickness such as kinetosis.

Using the electronic travel sickness assessment system 3 In particular, an improvement in a customer experience and an increase in traffic safety can be achieved through a lower occurrence of kinetosis symptoms. At the same time, the time gained can be used more effectively in an automated driving mode of the vehicle 1 be made possible. Using the electronic travel sickness assessment system 3 The occurrence of kinetosis symptoms can be prevented in advance through various actions and recommendations for action. In particular, this can result in the vehicle driver being ready to take over as a passenger 2 getting produced. This is particularly advantageous if the journey is at least partially autonomous (autonomy level 1 until 3 ) Driving an autonomously operable vehicle as a vehicle 1 acts. In the case of at least partially autonomous travel, the vehicle dealer, in this case the passenger 2 to be able to take command of the locomotion at any time. So it is essential that the passenger 2 , as a vehicle driver, does not experience motion sickness. An early reduction or avoidance of kinetosis symptoms is therefore important.

In particular, the kinetosis symptoms can already be seen simply by looking at the passenger 2 from the vehicle 1 can be reached out in the longitudinal direction of the vehicle.

Next to the one passenger 2 can using the electronic motion sickness assessment system 3 everyone in the vehicle 1 passengers are checked and monitored for possible motion sickness.

In particular, either at the beginning of the locomotion or continuously during the locomotion with the aid of the electronic travel sickness assessment system 3 a situation analysis of the passenger 2 carried out. In particular, the passenger 2 itself with the help of a camera system 4th supervised. Likewise, with the help of the camera system 4th a secondary activity or a secondary task, which is carried out by the passenger 2 is carried out during the locomotion, monitored.

In particular, with the camera system 4th the passenger 2 can be recorded while moving. Depending on the information recorded relating to the passenger 2 can for example use the electronic travel sickness assessment system 3 be assessed whether the passenger's motion sickness 2 occurs or has already occurred. Various instructions and / or countermeasures can then be given to the passenger 2 to be provided. In particular, with the camera system 4th an information content 5 which on one of the passenger 2 observed medium unit 6th in the vehicle 1 is represented. With the information content 5 For example, it can be a video game or a racing simulation game or a newspaper article or a book or a comic scene or a crossword puzzle or an action film or a documentary. In particular, the most varied of information can be used as information content on the medium unit 6th being represented. At the medium unit 6th it can be, for example, a medium or a portable communication terminal or a smartphone or a tablet or a laptop or a smartwatch or an e-book or a magazine or a book or a crossword puzzle or an appointment planner or a calendar or a notepad or a working folder or an MP3 player.

In particular, the passenger will 2 through the information content 6th on the media unit 6th distracted while moving. In particular, it is the passenger 2 of the movement of the vehicle 1 at least partially or completely distracted. As a result, the passenger in particular looks 2 no longer out of the vehicle 1 and gets the surroundings while the vehicle is moving 1 no longer with. This distraction can in particular lead to motion sickness or cause serious symptoms of motion sickness.

With an evaluation unit 7th can be the information content 5 are evaluated, so that depending on the assigned information content 6th the motion sickness can be assessed.

With the evaluation unit 7th it can be, for example, a vehicle system or a web application or an application on a portable communication terminal or an external server.

Furthermore, with the evaluation unit 7th the information content 5 the medium unit 6th be categorized. In this way, a type of secondary activity can be assigned to a certain disease state of motion sickness. In particular, the information content 5 the medium unit 6th a given level 8th a step model 9 be assigned. In particular, the step model 9 at least two different levels 8th a course of motion sickness. In this way, a precise assignment of the current course of the disease or a stage of the disease of the travel sickness can be made to the current information content displayed 5 the medium unit 6th be assigned.

For example, it can be in the case of the step model 9 be a database of an external server or an external service provider. as well can do the step model 9 in the evaluation unit 7th be implemented. The evaluation unit 7th can depending on the assigned level 8th assess and evaluate motion sickness more precisely and more precisely.

For example, with the at least two stages 8th of the step model 9 a symptom severity and / or a time course and / or a duration of illness and / or a severity and / or an illness prognosis and / or an acuteness of the motion sickness can be characterized. Thus, using the steps 8th of the step model 9 the current stage of motion sickness of the passenger can be precisely determined and assessed. A precise assessment of the health of the passenger can thus be carried out at any time 2 while moving in the vehicle 1 be performed.

For example, the evaluation unit 7th a database 10 exhibit. In the database 10 can, for example, use the step model 9 be saved.

For example, the passenger 2 the electronic travel sickness assessment system via an input unit before the start of the journey 3 Communicate whether they are more prone or less prone to motion sickness. Thus, the electronic travel sickness judgment system can take this into account when judging the motion sickness.

For example, it can happen that the information content 5 the medium unit 6th from the camera system 4th could not be captured. In this special case, the information content that is not recorded 5 be assigned to a special category. For example, the special category can be a basic setting or a default value of the electronic travel sickness assessment system 3 Act. With the help of the special category, a predetermined period of time and / or time threshold from which the passenger can be established 2 despite the imprecise determination of the information content 5 attention is drawn to a possible motion sickness or possible kinetosis symptoms. This allows the passenger 2 Be informed at all times and precisely about the current condition or the course of the illness of travel sickness. As a result, appropriate countermeasures to counteract motion sickness can be taken at an early stage.

For example, the camera system 4th a machine learning unit 11th exhibit. With the help of the machine learning unit 11th can the camera system 4th based on the unrecognized information content 5 be trained mechanically and automatically. This means that later recordings of the information content can be better assessed and evaluated.

For example, depending on the assessment of the travel sickness, a recommendation for action and / or information about action and / or a warning and / or a countermeasure and / or an action and / or a system intervention can be given to the passenger 2 to be provided. Based on this information, the passenger can 2 be informed of the current assessment of motion sickness. This can cause motion sickness of the passenger 2 alleviate and / or prevent motion sickness. In particular, this will benefit the passenger 2 advised to get his current look from the vehicle 1 to judge beyond. Likewise, it should help the passenger 2 be made aware of the secondary activity with the medium unit 6th currently pause. Thus, the passenger 2 advised to direct your attention currently to the movement of the vehicle in order to counteract motion sickness.

Likewise, the electronic travel sickness assessment system 3 provide further initialization options for motion sickness. For example, another passenger may experience motion sickness in the passenger 2 to the electronic travel sickness assessment system. It is also conceivable that the electronic travel sickness assessment system 3 independently and automatically assesses motion sickness. It is also conceivable that the passenger 2 self-initiated signaling to the electronic travel sickness assessment system 3 to report that he is feeling unwell and has symptoms of motion sickness or other health impairing symptoms.

There is also the possibility of using the electronic travel sickness assessment system 3 Settings by the passenger 2 before starting the journey with the vehicle 1 for the assessment of motion sickness. For example, the passenger 2 determine the severity of motion sickness appropriate warnings should be given. For example, from a certain severity of symptoms and / or acuteness of the motion sickness, only the recommendations for action can be given to the passenger 2 to be provided. Thus, the passenger can 2 stipulate that if the symptoms of motion sickness are minor, they will not be overloaded with too much information.

For example, it can be the electronic travel sickness assessment system 3 be an assisted kinetosis avoidance module or an assisted kinetosis avoidance mode of a vehicle system or external system.

For example, with a portable communication terminal 12th of the passenger 2 the passenger 2 can be recorded continuously while the vehicle is moving. For example, the portable communication terminal 12th one to the medium unit 6th be a separate device. In particular, it is the portable communication terminal 12th around the media unit 6th , which during the journey by the user 2 is operated and applied. In particular, the passenger will 2 using a camera (front camera and / or rear camera) of the portable communication terminal 12th supervised. In the portable communication terminal 12th it is in particular a smartphone or a tablet.

In particular, with the portable communication terminal 12th as a media unit 6th another piece of information 13th the passenger 2 are displayed while moving. For example, with the further information content 13th App applications and / or video services and / or streaming services on the portable communication terminal 12th the passenger 2 being represented. In particular, with the aid of a system of the portable communication terminal 12th and / or with the evaluation unit 7th the recorded information of the passenger 2 and the recorded further information content 13th be evaluated and assessed with regard to motion sickness.

In particular, the use of the portable communication terminal 12th for capturing the passenger 2 then beneficial when the passenger 2 when moving in an airplane or in a train or in a ship or in a ferry and / or in the back seat of the vehicle 1 is located. Likewise, the portable communication terminal 12th then find use when the camera system 4th is not operational or defective. Likewise, with the help of the portable communication terminal 12th a current position of the passenger 2 can be determined during the journey.

For example, you can use a microphone 21 , which is on the vehicle's instrument cluster 1 is arranged, the pronunciation and / or the breathing sound of the passenger 2 captured or recorded. In particular, the detection device 20th contain various measurement systems for collecting physiological data from humans. For example, the detection device 20th have a speech dialogue system with which the pronunciation of the passenger 2 can be analyzed.

In particular, with the aid of the detection device 20th an accurate assessment of the passenger's current state of health 2 be performed.

the 3 also shows the area around the driver's seat of the vehicle 1 .

For example, the provided recommendations for action and / or information and / or warning notices and / or countermeasures and / or actions can be given to the passenger 2 with an output unit 22nd be output acoustically and / or optically and / or haptically and / or olfactory. Thus, in the most varied of ways and with the most varied of output types, the passenger 2 the information about motion sickness is transmitted. In particular, it can be achieved through the various options that the passenger 2 really perceives the indications of motion sickness.

In particular, it is recognized that the passenger 2 is distracted, takes place after a predetermined period of time or on the basis of the comparison of the physiological properties of the passenger 2 an automatic system intervention by the electronic travel sickness assessment system 3 . With the output unit 22nd the corresponding notices are output. For example, the duration can be determined as a function of the recorded information content. The duration can also be determined on the basis of health studies. In particular, the duration can be an average of study results.

For example, you can use speakers 23 the notification information to the passenger 2 be output acoustically. The speakers can 23 Part of the vehicle's infotainment system 1 or be integrated into the vehicle interior as a separate loudspeaker.

For example, the output unit 22nd a lighting device 24 exhibit. With the lighting equipment 24 it can be, for example, a light source and / or a light band. The lighting device 24 can for example at the A- pillar 17th or the footwell of the vehicle 1 be arranged. With the help of the lighting equipment 24 can in particular an optical light pattern in the interior of the vehicle 1 are issued. Thus, the passenger can 2 be made aware of the assessed travel sickness.

Another possibility to draw the passenger's attention to the assessed travel sickness is via an olfactory output type. Thereby, an odor becomes a source of odor 25th in the interior of the vehicle 1 sprayed. In particular, this can be done using a fan 26th be performed. By the fan 26th it is a ventilation system or ventilation system of the vehicle 1 or a separate unit.
