Description

System for increasing the travel comfort of at least one occupant in a vehicle

description

The invention relates to a system for increasing the travel comfort of at least one occupant in a vehicle, in particular for suppressing symptoms of kinetosis, the system comprising at least one vehicle seat which is arranged in a vehicle interior, the system comprising at least one sensor device which detected at least one sensor parameter.

In vehicles that are used to transport people, for example cars, more and more attention is being paid to the comfort of travel that is offered. The time spent in a vehicle should be made as comfortable as possible for the occupant. For some people, however, travel or motion sickness represents a major impairment of travel comfort. Travel or motion sickness, technically kinetosis, is the name given to physical reactions such as paleness, dizziness, headache, nausea and vomiting caused by unfamiliar movements, for example in a means of transport , can be triggered. Motion sickness symptoms occur when the central nervous system receives conflicting messages from the sense organs. Accordingly, the inner ear, the eyes, the skin pressure receptors and the muscle and joint sensitive receptors report contradicting information. Around a third of the population is susceptible to motion sickness. Those who remain can also suffer from motion sickness in extreme conditions.

However, traveling in cities with tight curve radii under automated conditions is considered an extreme condition. The fixation on the environment, apart from the street , viewed as an extreme condition. After all, low-frequency vibrations (<0.4 Hz) with high amplitudes are more likely to cause the symptoms of motion sickness than frequencies in the range> 1 Hz (Andreas Koch, Ingolf Cascorbi, Martin Westhofen, Manuel Dafotakis, Sebastian Klapa, Johann Peter Kuhtz-Buschbeck: ” The Neurophysiology and Treatment of Motion Sickness ”Dtsch Arztebl Int. 2018 Oct; 115 (41): 687-996. Published online 2018 Oct 12. doi: 10.3238 / arztebl.2018.0687).

In the case of vehicles that support autonomous driving, the aspect of travel comfort is even more important, since the occupant or driver is not or only little occupied with the control of the vehicle and thus wants to make the journey time as comfortable as possible. Autonomous driving is also called automatic driving and is defined as the movement of vehicles that are largely autonomous. It is usually divided into different levels of autonomy (0-5). With autonomy level 0, the driver operates the vehicle himself. As the autonomy level increases, the driver's interaction with the vehicle decreases. Driving is fully automated in autonomy level 5. No driver is required. There is also no longer any talk of a driver, but of a supervisor, also known as a “third-ger”. No human intervention is required other than setting the destination and starting the system.

In such autonomous vehicles, the occupants have increased demands with regard to comfort. When people interact with a product, they perceive it through sensory information on several channels at the same time. The experience of comfort in this interaction is the result of the internal human calculation of this sensory input to a holistic impression in a fluid process over the interaction time. Comfort is only achieved when all aspects of the product are able to achieve a good level. Humans calculate this holistic interaction assessment with little conscious effort and usually with little awareness of their components. If, however, one aspect moves into the focus of the user and prevails in the overall impression, it dominates the comfort rating. This can happen in both directions: The negative event was referred to as the "limiting comfort factor", which means that the holistic comfort experience cannot be better than its weakest aspect.

The positive event can be described as the "wow factor" of a product that exceeds the expectations of the user. The object of the present invention is accordingly to provide a system for increasing the travel comfort of at least one occupant in a vehicle.

This object is achieved by the subject matter of claim 1. The subclaims represent possible advantageous embodiments.

The system according to the invention is suitable and provided for increasing the travel comfort of at least one occupant in a vehicle, in particular for suppressing symptoms of kinetosis, the system comprising at least one vehicle seat which is arranged in a vehicle interior, the system at least one sensor device which detects at least one sensor parameter, the system comprising at least one first control device, by means of which at least one comfort device can be controlled directly or indirectly in order to modify at least one comfort parameter, the comfort parameter being modifiable at least on the basis of the at least one sensor parameter, with at least a comfort device is designed as a lighting device, where the modifiable comfort parameters include lighting parameters.

The system can accordingly modify comfort parameters which influence the passenger's perception of comfort. This modification takes place on the one hand on the basis of at least one sensor parameter which is supplied to the control device by the at least one sensor device. However, the modification can also take place on the basis of other control signals or inputs. The modification based on the at least one sensor parameter has the advantage that comfort parameters are automatically modified by the first control device. The present invention can therefore serve both to suppress motion sickness and to optimize the perception of a feeling of comfort. One factor which, on the one hand, may prevent or reduce motion sickness and which has a significant influence on the comfort experience, is the lighting in the vehicle interior. Thanks to the automatic modification of the lighting parameters, which is individually tailored to the occupant, the symptoms of motion sickness can be prevented or reduced even before they occur.

The first control device advantageously compares the at least one sensor parameter with at least one predefined setpoint / limit value or setpoint / limit value range. The modification of the at least one comfort parameter, or the activation of the At least one comfort device is advantageously carried out when there is a deviation from, or when the setpoint / limit value or setpoint / limit value range is exceeded or not reached. Corresponding countermeasures can thus be initiated automatically by the control device even before a deterioration in the comfort experience is perceived. The at least one setpoint / limit value or setpoint / limit value range can advantageously be stored in a memory device. The storage device can preferably be connected to the first control device in terms of signaling. It would also be conceivable for the first control device to call up the setpoint / limit value or setpoint / limit value range from an external memory device.

In the case of direct activation, the control device would send corresponding control signals to the convenience device. In the case of indirect control, at least one further control device is provided which controls the comfort device. The first control device would send the corresponding commands for modifying the comfort parameters to this at least one further control device, whereupon it controls the comfort device or also further subordinate control devices.

According to a further preferred embodiment, the sensor device comprises at least one external sensor device which detects parameters of the environment relative to the vehicle. Such external sensor devices can be, for example, a speed sensor device, an acceleration sensor device, a rotation rate sensor device, a sensor device for detecting the road condition, a sensor device for detecting the ambient light conditions, a sensor device for detecting the ambient temperature. Such an external sensor device can also be a navigation device, by means of which speed, road conditions, winding roads, etc. can be detected.

A rotation rate sensor device can preferably be provided for the detection of rolling movements, pitching movements and yawing movements of the vehicle. Excessive cornering and / or excessive vehicle vibration can also cause motion sickness. At least one sensor device can preferably be provided which detects a repeated movement of the vehicle in the vertical and / or horizontal direction. These can be acceleration sensors, for example. Vertical and / or horizontal movements of the vehicle can be caused by uneven ground and be a possible cause of motion sickness. Accordingly, a sensor device for detecting vibrations, for example an acceleration sensor device, can be provided be. Many people experience motion sickness when the visual impression is too excessive, which also changes quickly. This can be the case in cities, for example. A far-reaching view of a landscape that does not change much, however, causes fewer motion sickness. Accordingly, a sensor device can be provided which detects visual properties of the environment. In particular, the rate of change in the environment is crucial. For this purpose, a corresponding image analysis could be provided, by means of which a value relating to a rate of change of the environment can be determined. Furthermore, a sensor device can be provided which detects the preceding curves in the roadway. The sensor device preferably comprises at least one internal sensor device which detects parameters of the vehicle interior. Such parameters can be, for example, the temperature, air humidity and the lighting conditions in the interior. The sensor device preferably comprises at least one internal sensor device which detects the position and / or orientation of the occupant in the vehicle interior. The sensor device preferably comprises at least one internal sensor device which detects the position and / or orientation of the occupant's head. The detection of the head position or the orientation of the occupant is important in order to modify comfort parameters effectively for the occupant. It would also be conceivable that an internal yaw rate sensor device is provided for the detection of cornering, rolling movements, pitching movements and yawing movements of the at least one vehicle seat. It would also be conceivable that an internal speed sensor device and an internal acceleration sensor device are provided for the detection of movements or changes in movement of the vehicle seat. Of course, other sensors are also conceivable with which further parameters causing travel sickness can be determined.

According to a further preferred embodiment, the lighting device comprises at least one lighting element. The at least one lighting element is preferably provided in the vehicle interior. The lighting device advantageously comprises at least one ceiling lighting element. The lighting device preferably comprises at least one floor lighting element. The lighting device preferably comprises at least one side lighting element. Furthermore, it would be conceivable to have at least one lighting element in the footwell of the vehicle in or on a center console of the vehicle, in or on a door of a vehicle, in or on an upper area of a door of a vehicle, in or on a lower area, for example the side compartment a door of a vehicle, to be provided in or on a center console of the vehicle. It would also be conceivable to provide at least one lighting element on handle elements, for example the door handle elements. Likewise, at least one lighting element could be provided in or on a display device in the front area of the vehicle. The lighting elements are advantageously arranged in the immediate vicinity of the at least one vehicle seat. An individual lighting element set is preferably assigned to the at least one vehicle seat. The lighting element set advantageously comprises at least one lighting device. If several vehicle seats are provided in the vehicle interior, a lighting element set is assigned to each vehicle seat so that individual lighting is made possible for the respective occupant. It can be advantageous that the lighting element set is arranged in the immediate vicinity of the at least one vehicle seat. It would be conceivable that certain lighting elements, which are associated with different sets of lighting equipment, are combined in a higher-level device. For example, several ceiling lighting elements can be combined in a higher-level ceiling device. It would also be conceivable that certain lighting elements are associated with several lighting element sets. On the basis of the individual specifications of different occupants, opposing controls can be provided for such a lighting element belonging to several lighting sets. In such a case, the first control device advantageously outputs a collision warning. Furthermore, a first control device can suggest at least one compromise solution, which can be, for example, averaging of the two specifications. The lighting device or the lighting elements can be modified with regard to various lighting parameters. Exemplary lighting parameters are the lighting intensity, the light color, the brightness or luminescence or the targeted control of certain lighting elements or the position of the lighting. At least two lighting parameters are advantageously modified in combination. At least three lighting parameters are advantageously modified in combination. Accordingly, the at least one lighting element is designed to emit different colors of light, to modify the light intensity, the brightness or luminescence. Accordingly, the at least one lighting element can be designed as an RGB element. Advantageously, the at least one lighting element is designed as an LED RGB element. Such elements allow adjustment in a wide range of colors. Of course, suitable lighting elements designed in other ways are also conceivable.

An adjustment of the light color can also correspond to an adjustment of a so-called light heat. The light heat is usually given in Kelvin. A cool light has one greater proportion of the color blue, whereas a warmer light has a greater proportion of the colors red and yellow. The light temperature has a not to be disregarded influence on the well-being. So-called daylight white light with more than 5200 Kelvin corresponds to daylight, during lunchtime it has a positive effect on well-being and promotes concentration. So-called neutral white light with approx. 3200 to approx. 5200 Kelvin leaves a more objective impression. Finally, the so-called warm white light is also differentiated with approx. 2700 to 3200 Kelvin. This light has a large proportion of red and has a relaxing effect. If symptoms of motion sickness occur, the light color can be modified to a warmer area, which has a relaxing effect. The lighting can also be modified to a certain predetermined color, which has a positive effect on the person concerned.

The color of the interior also determines the ambience in the interior of the vehicle. For this purpose, the color of the interior can be designed in such a way that it conveys an impression of security and directs the eye to important elements by working with light and dark, color-coordinated tones. Haptic properties support the functionality of the elements, soft for the body's own support zones, smooth for cladding and robust for storage. Furthermore, the colored room lighting in the interior can have a positive effect on the mental state of the occupants. The color of the interior also determines the ambience in the interior of the vehicle. For this purpose, the color scheme of the interior can be designed in such a way that it gives an impression of security and directs the eye to important elements by working with light and dark, color-coordinated tones. Haptic properties support the functionality of the elements, soft for the body's own support zones, smooth for cladding and robust for storage. If symptoms of motion sickness occur, the light color can be modified to a warmer area, which has a relaxing effect. The lighting can also be modified to a certain given color, which has a positive effect on the person concerned. The at least one lighting element can also be controlled by the first control device in such a way that a change in color indicates a change in movement (deceleration / acceleration). For this purpose, data from the first sensor device, for example the speed sensor device, the acceleration sensor device or the sensor device for detecting cornering can be evaluated by the first control device. According to a further preferred embodiment, the at least one lateral lighting element is designed in a strip-like manner. The at least one lateral lighting element is advantageously arranged on at least one side wall of the vehicle interior. The at least one side wall preferably delimits the vehicle interior. Advantageously, at least one lateral lighting element is arranged on a side wall, which extends along the longitudinal direction of the vehicle. As a rule, at least one door and at least one side window is provided in this side wall. It is advantageous that the at least one, preferably strip-like, lateral lighting element is arranged directly below or in an area close to the at least one side window. Advantageously, at least one lateral lighting element is arranged on a side wall, which extends along the width direction of the vehicle. These side walls are also referred to as the front or rear area of the vehicle interior. As a rule, at least one windshield or at least one rear window is provided in this side wall. It is advantageous here that the at least one, preferably strip-like, lateral lighting element is arranged directly below or in an area close to below the at least one windshield and / or the at least one rear window. At least one lateral lighting element advantageously extends over the entire lateral circumference of the vehicle interior. It is advantageous here that certain sections of the at least one lateral lighting element can be controlled individually in order to enable an individual adaptation to the occupant in the corresponding section.

An artificial horizon can advantageously be generated by the at least one lateral lighting element. Such an artificial horizon is used to resolve the perception conflict between the sensory organs generated by the movement of the vehicle and to counteract travel sickness.

According to a further preferred embodiment, at least one comfort device is designed as a vehicle seat adjustment device of the at least one vehicle seat. The modifiable comfort parameters preferably include suspension parameters and / or damping parameters of the vehicle seat. The vehicle seat adjustment device preferably comprises at least one multiaxial suspension / damping module, by means of which the suspension parameters and / or the damping parameters of the vehicle seat can be actively or semi-actively controlled and / or regulated. One possible factor that promotes motion sickness is the force applied to the occupant. Such forces can be, for example, lateral forces caused by cornering or lane changes, be. Other forces acting on the body can cause the vehicle to accelerate positively or negatively. Finally, a corresponding force can be exerted on the occupants by vibrations of the vehicle due to unevenness in the roadway. Corresponding countermeasures in the form of a modification of the comfort parameters, suspension parameters and / or damping parameters can be carried out automatically by the vehicle seat adjustment device. A first suspension / damping module is preferably provided, by means of which vertical oscillations, vibrations or deflections of the vehicle seat can be sprung and / or damped. A second suspension / damping module is preferably provided, by means of which horizontal oscillations, vibrations or deflections of the vehicle seat can be sprung and / or damped. The first and / or the second suspension / damping module and / or a third suspension / damping module is preferably provided in order to cushion and / or dampen rotational deflections, rotational oscillations or rotational vibrations. Rotationsauslenkun gene, rotational oscillations or rotational vibrations arise, for example, by rolling movements, ie deflections, oscillations or vibrations about an axis parallel to a longitudinal axis of the vehicle and / or the vehicle seat or by pitching movements, ie deflections, oscillations or vibrations about an axis parallel to the Breitenach se of the vehicle and / or the vehicle seat or yaw movements ie deflections, oscillations or vibrations about an axis parallel to the height axis of the vehicle and / or the vehicle seat. It would also be conceivable that only one suspension / damping module is provided, by means of which vertical oscillations, vibrations or deflections as well as horizontal oscillations, vibrations or deflections and the rotary oscillations, vibrations or deflections can be sprung and / or damped. A suspension / damping module can advantageously comprise a spring device for vibration isolation, for example an air spring. Alternatively or cumulatively, the suspension / damping module can comprise a damping device by means of which the vibrational energy introduced can be dissipated. Such a damping device can be a hydraulic shock absorber, for example.

The modification of the comfort parameters, suspension parameters and / or damping parameters can advantageously take place in such a way that the head of the occupant is moved as little as possible by the external influences caused by the journey. Such a measure can effectively suppress the symptoms of motion sickness or even prevent them in advance. An advantageous multiaxial suspension / damping module can minimize the movement of the head caused by vehicle vibrations, cornering, braking, accelerating, etc. Travel sickness can be counteracted by reducing head dynamics by using sprung and / or damped vehicle seats. The advantageous at least one multiaxial suspension / damping module intercepts most of the high-frequency vibrations and dampens very low frequencies with a high amplitude. Since the advantageous at least one multiaxial suspension / damping module cushions and / or dampens vertical and / or horizontal vibrations, the occupant's head can be kept as still as possible, while the sagittal body plane can incline a few degrees. This effectively counteracts the effects of lateral forces, when cornering or when changing lanes. The at least one multiaxial suspension / damping module can preferably also include various systems for roll and / or pitch compensation. The roll and / or pitch compensation is intended on the one hand to compensate for nodding movements forwards and backwards. Furthermore, fluctuations or lateral inclinations should be compensated for. The advantageous goal is that the head of the occupant is moved as little as possible. Even people who do not suffer from motion sickness can benefit from such a design of the system, since their body is isolated from the movement of the vehicle. This significantly increases the feeling of comfort. By effectively isolating the vehicle from the movement of the vehicle, activities such as reading or working on the computer can be carried out better while driving. By advantageously relocating the solution to the task of "ensuring comfort" from the chassis to the seat, the "eternal battle" between driving comfort and driving safety is resolved in the development of the chassis. A very comfortable suspension makes the vehicle unsafe, for example rollover, etc. On the other hand, a hard sports suspension can only be driven for a short period of time without any health consequences.

The vehicle seat preferably comprises a seat part and / or a backrest element and / or a headrest and extends along a height axis, a width axis and a longitudinal axis. The vehicle seat can advantageously also comprise at least one armrest element and / or a legrest. According to a further advantageous embodiment, the vehicle seat adjustment device comprises at least one seat position module, by means of which a comfort parameter in the form of a seat position parameter can be modified. A seat position parameter in the form of a seat height can preferably be modified by means of a first seat position module. A seat position parameter in the form of a seat inclination can preferably be modified by means of a second seat position module. A seat position parameter in the form of an inclination of a backrest can preferably be modified by means of a third seat position module. A seat position parameter is preferably provided by means of a fourth seat position module Modifiable in the form of a height of a headrest. A seat position parameter in the form of an inclination of a headrest can preferably be modified by means of a fifth seat position module. A seat position parameter in the form of an orientation with respect to an axis of rotation of the vehicle seat can preferably be modified by means of a sixth seat position module. The axis of rotation advantageously runs parallel to the height axis.

According to a further preferred embodiment, a displacement device is provided on which the at least one vehicle seat is displaceably arranged. The displacement device is advantageously arranged between the body floor of the vehicle and the at least one vehicle seat. The displacement device preferably comprises a rail system. A seventh seat position module is preferably provided, by means of which a seat position parameter in the form of a displacement position of the vehicle seat on the guidance system can be modified. The seventh seat position module advantageously comprises a locking device, by means of which the seat can be locked at a certain position. Alternatively, it would also be conceivable that the displacement device comprises rollers which are arranged on the at least one vehicle seat. The seventh seat position module would accordingly have a magnet system for anchoring the vehicle seat, for example. Such a configuration enables even greater freedom of movement for the occupant.

According to a further preferred embodiment, the at least one suspension / damping module comprises an energy recovery device, by means of which kinetic energy from multiaxial vibrations of the vehicle seat can at least partially be converted into electrical energy. This energy recovery device (energy harvesting) allows kinetic energy of the vehicle seat, caused by the vertical and / or horizontal vibrations, to be at least partially converted into electrical energy, which can be fed to the vehicle's on-board system.

According to a further preferred embodiment, the system comprises a seat arrangement which ensures an essentially complete spatial perception of the vehicle interior. The seat arrangement preferably comprises the at least one vehicle seat, more preferably a plurality of vehicle seats. Furthermore, the seat arrangement can be varied in such a way that the occupants are allowed a certain degree of free movement without having to neglect safety aspects. This variation can be ensured by the advantageous arrangement of the at least one vehicle seat on a displacement device become. The at least one seat position module, or a plurality of the seat position module already mentioned, allow at least one seat position parameter or a plurality of seat position parameters to be changed. This enables a certain degree of free movement without neglecting safety aspects. One factor which, on the one hand, may prevent or reduce motion sickness is the spatial perception of the vehicle interior and the possibility of free movement in the vehicle interior.

A classic seat arrangement in a vehicle comprises two rows of seats arranged side by side. Such an arrangement is desirable in conventional vehicles, since here the driver has to control the vehicle (autonomy level 0). In the case of higher autonomy levels, in particular in the case of autonomy level 5, such a seat arrangement can be deviated from.

To suppress the symptoms of motion sickness, a seating arrangement that deviates from the classic seating arrangement is beneficial. A vehicle interior is usually a rectangular, cubic, cuboid, hexahedron-shaped or polyhedron-shaped space. The advantageous seat arrangement comprises an arrangement of the at least one vehicle seat in a corner area of the vehicle interior. A vehicle seat is preferably provided in two, three or four corner areas of the vehicle interior. The at least one vehicle seat can preferably face or face the vehicle interior. The vehicle seats are preferably facing the interior and optionally facing each other. Such an orientation can be modified as required by the advantageous sixth seat position module. This ensures a complete spatial perception of the vehicle interior. Such a seating arrangement supports the cognitive abilities of the occupants for the best possible understanding of the interior.

Spatial perception is defined as the ability to perceive spatial relationships in relation to the alignment of one's own body despite distracting information. This is a significant factor in increasing the enjoyment of space and counteracting motion sickness. Compared to the classic seating arrangement, in which the occupants in the first row only partially perceive the interior due to their forward view and the passengers in the second row only have a limited view of the interior because the front seats block their view, one occupant has Through the seating arrangement in the corner areas of the vehicle interior, the cognitive ability to visually grasp the interior space given by its geometric boundaries and the open space in the middle. This is a significant one Factor to increase the enjoyment of space and counteract motion sickness. A seating arrangement in which the occupants sit diagonally opposite each other is conducive to suppressing the symptoms of motion sickness.

According to a further preferred embodiment, the first control device modifies at least one lighting parameter based on the sensor data of the internal sensor device which detects the position and / or orientation of the occupant and / or the head of the occupant in the vehicle interior. Due to the described great freedom of movement of the occupant within the vehicle interior, it is necessary that the individual lighting, which is useful for suppressing motion sickness, for example, is adapted to the movement of the occupant. In this case, the orientation and / or the position of the occupant can advantageously be detected by means of the internal sensor device. Alternatively or cumulatively, the alignment and / or the position of the head of the occupant can be detected. The lighting is then modified according to these movements. The occupant can, for example, turn his head downwards, upwards, to the side or also backwards. The occupant can also turn his entire body forward, to the side, etc. On the basis of the data from the first sensor device, the first control device can control the comfort device in the form of the lighting device so that the occupant finds the desired lighting in every changing position or orientation. In the case of several occupants and possible colliding modifications, the first control device can advantageously output a warning signal and output possible compromise proposals for selection. It would also be conceivable that the control device calculates the best possible compromise modification and carries it out automatically.

According to a further preferred embodiment, at least one display device for displaying information data is provided. Such information data can be state data of the vehicle, such as speed, time, arrival time, engine parameters, navigation information and any other information data. Preferably, depending on the position and / or orientation of the occupant and / or depending on the position and / or orientation of the head of the occupant, the information data that is best visible to the occupant is displayed on the display device. The display device is preferably designed as a projection surface. At least one projection device is preferably provided which projects onto the at least one projection surface. A plurality of projection surfaces is preferably provided. Preferably, depending on the posi- tion and / or alignment of the occupant and / or the head of the occupant, the at least one projection device is controlled by the first control device, so that the projection takes place on the projection surface that is best visible to the occupant. This activation is preferably limited to the driver / supervisor of the vehicle. In the case of a classic alignment with a view through the windshield, a first projection surface is arranged in an area below the windshield in which the usual dashboard displays can also be expected. If the occupant turns away from this position / orientation, the information data can be displayed on a nearby projection surface. Alternatively or cumulatively, the at least one display device can also be designed as a display device which is operated in an analogous manner. The at least one display device or the at least one projection device can preferably also be modified with regard to the lighting parameters.

According to a further preferred embodiment, the system comprises an interface device which is signal-connected to the first control device. The at least one setpoint / limit value or setpoint / limit value range can preferably be entered and / or modified by means of the interface device. Modification parameters can preferably be entered and / or modified by means of the interface device. The modification parameters preferably determine the degree to which the comfort parameters are to be modified. The modification parameters preferably determine the degree to which the comfort parameters are to be modified as a function of the sensor parameters. Each occupant perceives the comfort experience differently. There are also individual differences in sensitivity with regard to motion sickness. Accordingly, it is advantageous that an occupant can modify the corresponding setpoint / limit value or setpoint / limit value range from which control of a comfort device is to take place. Furthermore, it is advantageous that the occupant can adjust the modification parameters, that is to say the degree of modification of the comfort parameters, in accordance with his or her comfort perception. A plurality of the same or different comfort devices is preferably provided. As a result, a number of comfort parameters can be modified. The control of at least one convenience device can preferably be specified by means of the interface device. The control can thus be adapted individually. The suppression of symptoms of motion sickness varies from person to person. Depending on the individual's feelings, a change in a certain comfort parameter can have a more effective effect on an occupant than another. The occupant can use the interface device to select which comfort parameters are to be modified and to what extent. The inmate can therefore choose any convenient, related Select an effective combination of comfort parameters and determine the degree of modification. Advantageously, at least one comfort parameter can be set manually by means of the interface device. The interface device can thus preferably comprise an input device and / or an output device or be connected to an input device and / or an output device for signaling purposes. A combined input and output device, for example a touch screen, would also be conceivable. An input device in the form of an operating device, which comprises at least one switch and / or at least one button, would also be conceivable. Alternatively, the input device can be provided and suitable for receiving voice inputs so that the comfort parameters can be modified by means of voice inputs. Alternatively, the input device can be provided and suitable for recognizing gestures, so that the comfort parameters can be modified by means of the gestures. Of course, further input devices can also be provided, by means of which the comfort parameters can be modified.

According to a further preferred embodiment, the modification of the comfort parameters takes place on the basis of predetermined profile data of an occupant. The profile data are matched to an occupant and advantageously include preferences of the occupant with regard to his individual comfort experience. The profile data can thus include the preferred at least one setpoint / limit value or setpoint / limit value range and / or the modification parameters and / or the preferred control of certain comfort devices and / or the preferred modification of comfort parameters. The profile data are advantageously stored in a memory device, which is preferably connected to the first control device for signaling purposes. The profile data can preferably be entered or modified by the interface device. The profile data or the profile can / can be activated by an occupant. The first control device is accordingly made available with regard to the comfort parameters. The occupant therefore no longer needs to make any further settings or inputs. This is particularly advantageous for occupants who use the vehicle regularly. The profile can be activated by making an entry. Such input can be a selection on a display, audio input, or a fingerprint. It would also be conceivable that face recognition is provided in the vehicle, which automatically activates a profile for an occupant in a specific seat. According to a further preferred embodiment, the interface device is connected to an input / output device by means of a wireless connection. The input / output device is preferably a smartphone and / or a tablet computer and / or a laptop. Such a wireless connection can be, for example, an RFID (radio-frequency identification) connection, an NFC (near-field communication) connection, a WLAN connection or a cellular connection. Of course, further wireless connections or wired connections can also be used. With this input / output device, the occupant can make all settings and inputs, for example the preferred at least one setpoint / limit value or setpoint / limit value range and / or the modification parameters and / or the preferred control of certain comfort devices and / or the preferred modification of Comfort parameters and / or the input / modification of the profile data. An automatic data exchange preferably takes place between the interface device or the first control device and the input / output device, in which an identification process is carried out. The profile data can preferably be activated automatically by the input / output device. The profile data are advantageously stored on the input / output device. The profile data can preferably be called up automatically via the interface device. The user can therefore automatically transmit his preferred settings to the first control device in different vehicles.

According to a further preferred embodiment, at least one comfort device is designed as an air conditioning device. The modifiable comfort parameters preferably include air conditioning parameters. An important factor with regard to motion sickness is the air conditioning of the interior. Such air conditioning can be modifiable on the basis of the at least one sensor parameter. The air conditioning can thus be individually tailored to an occupant. A modification of the air conditioning can accordingly be adapted automatically in the event of deviations from the at least one setpoint / limit value or setpoint / limit value range. Air conditioning of the vehicle can preferably be implemented by an air flow entering the vehicle interior. These air conditioning parameters accordingly include various air flow parameters which can be controlled by the first control device. Such air flow parameters can be, for example, the amount of air introduced, the direction of flow of the air flow, the temperature of the air introduced and the relative humidity. The air flow enters the vehicle through air inlet devices, which can be arranged in different positions of the vehicle. The air flow parameters can be effectively aligned on the basis of the orientation of the occupant or on the basis of the orientation of the head of the occupant. Thus, the air tromparameter also effectively adjusted when rotating or relocating the vehicle seat. The air conditioning parameters can, however, also include further parameters which are independent of an air flow, for example if a radiation heat source is used.

According to a further preferred embodiment, at least one comfort device is designed as a sound device. The modifiable comfort parameters preferably include sound parameters. Sounds have a significant impact on the comfort experience. The modification of the sound parameters can include, for example, the generation of sounds or music. Advantageously, these sounds can be of a calming nature. The sounds can be provided via individual speakers or headphones. The loudspeakers are advantageously integrated into the vehicle seat. It is also conceivable that the modification of the sound parameters also includes active noise compensation (Active Noise Reduction or Active Noise Cancellation). A sound is thus preferably generated artificially in order to extinguish sound by means of destructive interference. For this purpose, the aim is to generate a signal that corresponds exactly to that of the disturbing sound with opposite polarity. To this end, it is advantageous that the sensor device comprises a sensor device which detects the noise or sound present in the vehicle interior.

According to a further preferred embodiment, at least one comfort device is designed as a fragrance generating device. The modifiable comfort parameters preferably include fragrance parameters. In order to suppress travel sickness, a targeted release of certain fragrances and / or aromas can preferably also be advantageous.

According to a further preferred embodiment, the system comprises an entertainment facility. The at least one comfort parameter can advantageously be modified on the basis of a signal from the entertainment device. An entertainment facility can include entertainment programs in the form of games, interactive games, films, etc. The comfort parameters can be adjusted based on these entertainment programs. For example, the vehicle seat adjusting device can be modified according to an interactive game. This creates an effective entertainment or comfort experience. It is advantageous that the entertainment device comprises or at least one display connected to a display. At least one comfort device is preferably a fog display device. Such a fog display device or fog display or also called “fog curtain” is used to improve the ambience in the vehicle interior. Such a fog display device conveys an aerosol, ie a mixture (dispersion) of solid or liquid particles in a gas, for example air, to a specified location in the vehicle interior. This can take place, for example, in an eddy-free air flow into which particles, for example water particles, are injected, or simply by a flow of an aerosol that has already been generated. Such a fog display is, for example, an eddy-free air flow into which particles, for example water particles, are injected. This creates a thin fog surface. Images can either be projected from behind or from the front onto this fog surface. Such a fog display has the advantage of not being fragile. Furthermore, the space taken up by the fog display can simply be used for other purposes by switching off the fog display. Such a fog display can preferably be provided in the rear area of the vehicle interior. The fog display device can also serve as a scent generating device, ie for the release of scents.

A combination of comfort parameters is preferably modified to suppress motion sickness or to optimize the comfort experience.

A setting of the lighting can accordingly be adapted automatically in the event of deviations in the sensor parameters from the at least one setpoint / limit value or setpoint / limit value range. An individual adaptation of the lighting in the interior of the vehicle to the individual occupants can also make a corresponding contribution to the feeling of comfort.

The first control device 5 compares the at least one sensor parameter with at least one predetermined setpoint / limit value or setpoint / limit value range. If the sensor parameters deviate from the setpoint / limit value or setpoint / limit value range, the at least one comfort parameter is modified. The at least one setpoint / limit value or setpoint / limit value range is stored in a memory device 8, which is connected to the first control device 5 for signaling purposes.

Furthermore, the sensor device 4 can comprise at least one internal sensor device 21 which detects parameters of the vehicle interior 3. The sensor device 4 can also comprise at least one internal sensor device 22 which detects the position and / or orientation of the occupant in the vehicle interior 3. Such external sensor devices 20 can be, for example, a speed sensor device, an acceleration sensor device, a rotation rate sensor device, a sensor device for detecting the road condition, a sensor device for detecting the ambient light conditions, a sensor device for detecting the ambient temperature. Such an external sensor device 20 can also be a navigation device by means of which speed, road conditions, winding roads, etc. can be detected. A rotation rate sensor device can be provided for the detection of rolling movements, pitching movements and yaw movements of the vehicle. At least one sensor device can preferably be provided which detects a repeated movement of the vehicle in the vertical and / or horizontal direction. For this purpose, for example, corresponding acceleration sensor devices or position sensor devices can be provided with regard to certain components of the vehicle. Such vertical and / or horizontal movements of the vehicle can be caused by unevenness in the ground and be a possible cause of motion sickness. Excessive cornering can also cause motion sickness. Accordingly, a sensor device for determining cornering, for example a corresponding acceleration sensor input direction to be provided. The external sensor device can also be suitable for detecting visual properties of the environment. In particular, the speed of change in the environment is crucial.

The lighting device 24 comprises at least one lighting element 46. Such a lighting element 46 can be at least one ceiling lighting element 46a, which is arranged on or in a ceiling wall of the vehicle 100 and / or at least one floor lighting element 46c, which is arranged on or in a floor wall of the vehicle 100 and / or at least one lateral lighting element 46b, which is arranged on or in a side wall of the vehicle 100. This is shown in FIGS. 12 to 16 and 24. Furthermore, it would be conceivable to have at least one lighting element 46 in the footwell of the vehicle, in or on a center console of the vehicle, in or on a door of a vehicle, in or on an upper area of a door of a vehicle, in or on a lower area, For example, to provide the side compartment of a door of a vehicle, in or on a center console of the vehicle. It would also be conceivable to provide at least one lighting element 46 on handle elements, for example the door handle elements. Likewise, at least one lighting element 46 could be provided in or on a display device in the front area of the vehicle. Each vehicle seat 2, 2a, 2b in the vehicle interior 3 is assigned a specific individual lighting element set which comprises at least Be lighting elements. The lighting elements contained in the individual lighting element set can advantageously be arranged in the immediate vicinity of the respective vehicle seat. It would be conceivable that certain lighting elements 46, which belong to different sets of lighting means, are combined in a superordinate device. For example, several ceiling lighting elements 46a can be combined in a higher-level ceiling device. It would also be conceivable that certain lighting elements 46 are associated with several lighting element sets. The lighting device 24 or the lighting elements 46 can be modified with regard to various lighting parameters. Exemplary lighting parameters are the illuminance, the light color, the brightness or luminescence or the targeted control of certain lighting elements 46, or the position of the lighting. At least two lighting parameters are advantageously modified in combination. At least three lighting parameters are advantageously modified in combination. The lighting elements 46 can be arranged in the vehicle 1 in such a way that an individual lighting design is possible in the immediate vicinity of a vehicle seat 2, 2a, 2b. In this way, the lighting can be individually tailored to the occupant. An adjustment of the light color can also correspond to an adjustment of a so-called light heat. The lighting device 24 can also be modified to preview movements or speeds and serve for mood-dependent ambient lighting. Lighting elements 46 in the form of colored light strips can continue to indicate changes in movement (deceleration / acceleration). Furthermore, the colored room lighting in the vehicle interior 3 can have a positive influence on the mental state of the occupants.

The at least one lateral lighting element 46b can be designed in the manner of a strip or as a lighting strip and can be arranged on at least one side wall 102a, 102b which delimits the vehicle interior 3. The side lighting elements 46b can be arranged on a side wall 102a which extends along the longitudinal direction of the vehicle. As a rule, at least one door and at least one side window 103 are provided in this side wall. It is advantageous here that the at least one, preferably strip-like, lateral lighting element is arranged directly below or in an area close below the at least one side window 103. Furthermore, at least one lateral lighting element 46b can be arranged on a side wall 102b, which extends along the width direction of the vehicle 100. These side walls 102b are also referred to as the front or rear area of the vehicle interior 3. As a rule, at least one windshield 104a or at least one rear window 104b is provided in this side wall 102b. It is advantageous here that the at least one, preferably strip-like, lateral lighting element is arranged directly below or in an area close below the at least one windshield 104a and / or the at least one rear window 104b. At least one lateral circumference of the vehicle interior 3 advantageously extends over the entire lateral circumference Lighting element 46b.

By preferably continuous lighting of such a lateral lighting element 46b in the form of a lighting strip, an artificial horizon 47 can be generated in order to resolve the conflict of the sensory organs in perception and counteract travel illness. Of course, further differently shaped side lighting elements 46b can also be provided in the side areas.

The at least one comfort device 6 can be designed as a vehicle seat adjustment device 7 of the at least one vehicle seat 2, the modifiable comfort parameters including suspension parameters and / or damping parameters of the vehicle seat 2. The vehicle seat adjustment device 7 comprises at least one multiaxial suspension / damping module 9, by means of which the suspension parameters and / or the damping parameters of the vehicle seat can be actively or semi-actively controlled and / or regulated. A first suspension / damping module 9 can be provided, by means of which vertical deflections of the vehicle seat 2 can be sprung and / or damped. Furthermore, a second suspension / damping module 9 can be provided, by means of which horizontal deflections of the vehicle seat 2 can be sprung and / or damped. The first and / or the second suspension / damping module and / or a third suspension / damping module is preferably provided in order to cushion and / or dampen rotational deflections, rotational oscillations or rotational vibrations. Such rotational deflections, rotational oscillations or Rotati onsvibrationen arise, for example, by rolling movements, ie deflections, oscillations or vibrations about an axis parallel to a longitudinal axis of the vehicle 100 and / or the at least one vehicle seat 2 or by pitching movements, ie Auslenkun conditions, oscillations or vibrations around a Axis parallel to the width axis of the vehicle 100 and / or the at least one vehicle seat 2 or yaw movements, ie deflections, oscillations or vibrations about an axis parallel to the vertical axis of the vehicle 100 and / or the at least one vehicle seat 2. However, it would be It is also conceivable that only one suspension / damping module 9 is provided, by means of which both vertical and horizontal deflections of the vehicle seat 2 can be sprung and / or damped. Factors that promote motion sickness are the forces exerted on the person. Such forces can be lateral forces caused by cornering or lane changes. Other forces acting on the body can cause the vehicle to accelerate positively or negatively. Finally can through Vibrations of the vehicle due to unevenness in the road surface a corresponding force is transmitted to the occupants. Such force effects can be minimized or even prevented by the multiaxial suspension / damping module 9. It is advantageous that the multiaxial suspension / damping module 9 minimizes or even prevents unwanted movements of the occupant's head. Excessive head movement can cause motion sickness. It is therefore advantageous to minimize head movements. This can be done, for example, by modifying the suspension parameters and / or damping parameters.

The vehicle seat adjustment device 7 can comprise at least one seat position module 10, by means of which a comfort parameter in the form of a seat position parameter can be modified. It would be conceivable to provide a first seat position module 10a, by means of which a seat position parameter in the form of a seat height can be modified, and / or a second seat position module (10b), by means of which a seat position parameter in the form of a seat inclination can be modified, and / or a third Seat position module 10c, by means of which a seat position parameter in the form of an inclination of a backrest 31 can be modified, and / or a fourth seat position module 10d, by means of which a seat position parameter in the form of a height of a headrest 14 can be modified, and / or a fifth seat position module 10e, by means of wel chem a seat position parameter in the form of an inclination of a headrest 14 can be modified, and / or a sixth seat position module 10f, by means of which a seat position parameter in the form of an orientation with respect to an axis of rotation D of the vehicle seat 2 can be modified.

FIG. 4 shows an exemplary vehicle seat 2. The vehicle seat 2 extends along a height axis Z, a longitudinal axis X and a width axis Y. The vehicle seat 2 comprises a seat substructure 29 which comprises a slide element 30. This slide element 30 can be part of the displacement device 15, by means of which the vehicle seat can be displaced in the vehicle 100. The seat substructure 29 furthermore comprises the sixth Sitzpositi onsmodul 10f, in the form of a rotating device. As a result, the vehicle seat 2 is advantageously rotatable about the axis of rotation D, which preferably runs parallel to the vertical axis Z ver. The vehicle seat 2 can thus advantageously rotate through an angle between 5 ° and 180 °. The driver, or supervisor, can therefore orientate himself forward if he wants to monitor the journey, make entries in the driving console or temporarily take over the driving activity. Otherwise, he can turn to the vehicle interior 3. The sixth seat position module 10f can comprise a locking device, by means of which the rotary movement can be locked. Furthermore, the sixth sitting position tion module 10f be designed in such a way that the rotary movement is performed only by the muscle force of the occupant. Alternatively, the sixth seat position module 10f can be designed in such a way that the rotary movement is carried out by means of an actuator. The sixth seat position module 10f or the actuating drive is then advantageously controlled directly or indirectly by the first control device. The actuator can be driven electrically, hydraulically or by other suitable alternatives. The vehicle seat 2 further comprises a backrest 31, a seat part 32, a headrest 33 and at least one armrest 34. Furthermore, a preferably fold-out leg rest 35 can be provided, which is arranged pivotably on the vehicle seat 2.

The vehicle seat adjustment device 7 can also be arranged at least partially in the seat substructure. For example, the at least one multiaxial suspension / damping module 9 can be arranged in the seat substructure. Furthermore, various systems for roll and / or pitch compensation can be provided. The roll and / or pitch compensation is intended on the one hand to compensate for pitching movements forwards and backwards. Furthermore, fluctuations or lateral inclinations should be compensated for. The advantageous aim is to prevent the occupant's head from being moved as little as possible.

Possible systems for roll and / or pitch compensation, or multiaxial suspension / damping devices are in the publications DE 102018 124507.6, DE 102019 111 188.9, DE 102015 118442.7, DE 102018 124 512.2, DE 102018 112 036.2, DE 102017 128410.9, EP 2463 146 A2, DE 7 731 339U1, DE 102017 128 809 A1, DE 102015 121 764.3 and DE 102015 121 765.1, the content of which is intended to belong in full to the present disclosure.

An important factor here is to make the at least one suspension and / or damping module 9 as small as possible, since there is little installation space in the vehicle 100. This installation space is further limited by an advantageous displacement device with regard to the displacement of the seat in the vehicle interior and further advantageous seat position modules 10, 10a to 10g. In FIGS. 9 to 11, possible advantageous configurations for a suspension and / or damping module 9 are shown.

In Figures 5a and 5b, a possible advantageous suspension and / or damping module 9 is shown. Here, a lower part 36 and an upper part 37 spring-mounted opposite the lower part 36 by means of at least one damper device 38 is provided. The top 37 is suspended from the lower part 36, so that the upper part 37 can be pivoted when vibrations occur between the upper part 37 and the lower part 36 about a fictitious or real axis located below the upper part 37 and extending in the vehicle width direction or vehicle longitudinal direction. The lower part 36 and the upper part 37 are connected to one another by means of at least a first and a second pivot bearing. The first and second pivot bearings each include at least one lever arm 39, the first end of which is attached to the lower part 36 by means of a first pivot axis and the second end of which is attached to the upper part 37 by means of a second pivot axis, the second end being above the first end. The second pivot axis of the second pivot bearing can be displaced within a cam track attached to the lower part 36. A pivoting movement of the schwenkba Ren upper part 37 can be acted upon by means of the damper device 38 with a damping force counteracting the pivoting movement for vibration damping, the damper device 38 being connected to at least one of the lever arms 39 on the one hand and the lower part 36 on the other hand. A vehicle seat with such a device is disclosed in the document EP 2 463 146 A2, the content of which is intended to belong in full to the present disclosure.

Another possible embodiment of a possible advantageous suspension and / or damping module 9 is shown in FIGS. 6a, 6b, 6c and 6d. Here, too, a lower part 36 and an upper part 37 which is spring-mounted relative to the lower part 36 by means of at least one damper device 38 is provided. The upper part 37 is hanging on the lower part 36 Gela Gert. The at least one first pivot bearing comprises at least one first lever 39, the first end of which is attached to the lower part by means of a first pivot axis and the second end of which is attached to the upper part by means of a second pivot axis, the second end being below the first end as viewed in a height direction. Furthermore, at least the position of the first end of the lever 39 can be changed by means of an adjusting device. Furthermore, a damper device 38 is provided, by means of which the pivoting movement is counteracted. FIG. 6b shows a basic arrangement of a first and a second lever, which are aligned parallel to one another and run along the vertical axis Z.

The first and second ends of the lever 39 form a parallelogram, when the upper part 36 is pivoted relative to the lower part 37, the upper part 36 and the lower part 37 remain parallel to one another. This position is particularly preferred for isolating translations. In the embodiment according to FIG. 6c, the second ends of the levers 39 are moved further inward. When the upper part 36 is pivoted relative to the lower part 37, the upper part 36 is no longer parallel to the lower part 37 Rotation of the upper part 36 about a fictitious axis arranged below the upper part 36. This position is particularly preferred for isolating roll and pitch movements. In the embodiment according to FIG. 6d, the second ends of the levers 39 are moved further outwards. When the upper part 36 is pivoted relative to the lower part 37, the upper part 36 is no longer parallel to the lower part 37. This suspension particularly describes a rotation of the upper part 36 about a fictitious axis arranged above the upper part 36. This position is particularly preferred for isolating slopes and rolling and pitching movements. A vehicle seat with such a device is disclosed in patent applications DE 10 2015 121 764.3, DE 102015 121 765.1, the content of which is intended to belong in full to the present disclosure.

A further possible suspension and / or damping module 9 is shown in FIGS. 7a and 7b, FIG. 7a showing a top view in a non-deflected operating state and FIG. 7b showing a corresponding front view. The suspension and / or damping module 9 comprises a spring device for springing pivoting movements and a first damping device 38 for damping the pivoting movements of an upper part 37 of the vehicle seat 2 with respect to a lower part 36 of a vehicle seat 2, about a pivot axis extending in a longitudinal direction or width of the vehicle seat se and a second damping device 38 for damping a translational movement of the vehicle seat 2. The spring device has a first spring rod 41 which is elastically deformable in the transverse direction and extends in a vehicle seat longitudinal direction or vehicle seat width direction and a connecting part which can pivot about the pivot axis 40 and which connects the first spring rod and the pivot axis connects in order to deform the first spring rod 39 when the upper part 37 is pivoted. The first damping device 38 comprises a first damper with a first end and a second end, the first end being pivotably connected to the lower part 36 by means of a first pivot axis and the second end being pivotably connected to a first lever element 39 by means of a fifth pivot axis. The first lever element 39 is pivotably connected to the lower part 36 by means of a second pivot axis. Furthermore, a second lever element 39a is provided, which is pivotably connected to the first lever element 39 by means of a third pivot axis and pivotably to the upper part 37 by means of a fourth pivot axis. The second damping device has a second damper which is arranged perpendicular to the first spring bar in the vehicle seat width direction or the vehicle seat longitudinal direction. A vehicle seat with such a device is in the patent application DE 102018 112 036.2 disclosed, the content of which is intended to fully relate to the present disclosure.

The movement of the head due to vehicle vibrations, cornering, braking, accelerating, etc. is minimized by the suspension and / or damping module 9. A counteracting motion sickness can therefore be achieved by reducing the head dynamics through the sprung vehicle seat 2. The multiaxial suspension and / or damping module 9 intercepts most of the high-frequency vibrations and dampens very low frequencies with a high amplitude. Such multiaxial suspension and / or damping modules 9 spring and / or dampen vertical and / or horizontal vibrations. Such suspension and / or damping modules 9 are advantageously activated actively or semi-actively. Lateral forces when cornering or when changing lanes are counteracted with the horizontal suspension and / or damping devices. The occupant's head should be kept as still as possible, while the sagittal body plane can incline a few degrees. People who do not suffer from motion sickness will also benefit from such vehicle seats 2, since their body is isolated from the vehicle movement. This significantly increases the feeling of comfort. By effectively isolating it from vehicle movement, activities such as reading or working on the computer while driving can be carried out more easily.

The system 1 can comprise a seat arrangement 16, which ensures a substantially complete spatial perception of the vehicle interior 3 The seat arrangement 16 comprises the at least one vehicle seat 2. Furthermore, the seat arrangement 16 comprises an arrangement of the at least one vehicle seat 2 in a corner area of the vehicle interior 3, the at least one vehicle seat 2 facing the vehicle interior 3. One factor which, on the one hand, may prevent or reduce motion sickness, is the spatial perception of the vehicle interior 3 and the possibility of free movement in the vehicle interior. Accordingly, a seat arrangement 16 is proposed which ensures complete spatial perception of the vehicle interior 3. Furthermore, the seat arrangement 16 can be varied in such a way that the occupants are allowed a certain degree of free movement without having to neglect safety aspects.

FIGS. 12 and 13 show a classic seat arrangement in a vehicle 100 which comprises two rows of vehicle seats 2a, 2b arranged next to one another. With conventional Such an arrangement is desirable for borrowed vehicles 100, since here the driver must control the vehicle 100 (autonomy level 0). In the case of higher autonomy levels, in particular in the case of autonomy level 5, such a seat arrangement can be deviated from. To suppress the symptoms of motion sickness, a seating arrangement that differs from the classic seating arrangement is useful. A vehicle interior 3 is usually a rectangular cubic room. An arrangement of a respective seat 2a, 2b in a corner area of the vehicle interior 3 is desirable. At least one front vehicle seat 2a and at least one rear vehicle seat 2b are provided. The seats 2a, 2b continue to face the interior. This is shown in FIGS. 14 to 16, 18 to 22 and 24. This ensures a complete spatial perception of the vehicle interior. Such a seat arrangement 16 supports the cognitive abilities of the occupants for the best possible detection of the interior. Spatial perception is defined as the ability to perceive spatial relationships in relation to the alignment of one's own body despite distracting information. This is a significant factor in increasing the enjoyment of space and counteracting motion sickness. Compared to the classic seat arrangement (Figures 12 and 13), in which the occupants in the first row only partially perceive the interior 3 due to the forward view and the passengers in the second row only have a limited view of the interior because the front seats have their Blocking view, the seat arrangement 16 in the corner areas of the vehicle interior 3 (FIGS. 14 to 16 and 18 to 22) gives an occupant the cognitive ability to visually perceive the interior space given by its geometric boundaries and the open space in the middle sen. This is a significant factor in increasing the enjoyment of space and counteracting motion sickness. A seating arrangement in which the occupants sit diagonally opposite each other is conducive to suppressing the symptoms of motion sickness.

Seat arrangements are conceivable which only comprise two seats 2a, 2b. This is shown, for example, in FIGS. 14, 15, 20 to 22 and 24. FIGS. 18 and 19 show an arrangement with three seats 2a, 2b each, with one front seat 2a being provided in the front area of the vehicle interior in FIG. 18 and two rear seats 2b being provided in the rear area. In FIGS. 20 to 22, two seats 2a, 2b are provided, with a front seat 2a and a rear seat 2b being provided. Of course, an embodiment would also be conceivable in which 4 or more seats 2a, 2b are provided. In order to enable approximately free movement, the at least one vehicle seat 2 is arranged by means of a displacement device 15 on the body floor 101 of the vehicle 100. Such a displacement device 15 can be, for example, a rail system 15a, as shown in FIGS. 8 and 9. The rail system 15a advantageously extends from a respective corner region of the vehicle interior to the center of the vehicle interior. Accordingly, an angle α can be enclosed by the rail system 6 and the side wall of the vehicle interior. The angle a is preferably in a range between 15 ° and 75 °, more preferably between 25 ° and 65 °, more preferably between 40 ° and 45 °. On the one hand, the guidance in the rail system 15a ensures a certain freedom of movement; on the other hand, the seat 2a, 2b is also securely connected to the body floor 101 in a sufficiently secure manner. In FIGS. 8 to 10 it can be seen that the respective seat 2a, 2b comprises a slide element 30 which is connected to the rail system 15a.

FIG. 10 shows a possible embodiment of the sixth seat position module 10f, in the form of a rotating device which is driven by means of a toothed gear. It should be emphasized that not only the front seats 2a have the described options for displacement or rotation. Likewise, the rear seats 2b can be equipped ver relocatable and rotatable.

The seats 2a, 2b should leave the user with an optimal impression of comfort. Accordingly, the seats 2a, 2b can be inclined by means of a second seat position module (10b). The seats 2, 3 comprise a seat frame 41, which comprises a seat part 32 and a backrest 31 with a lumbar vertebra section 31 a, a shoulder section 31 b and a head part 33. It is advantageous if the lumbar vertebra section 31a, the shoulder section 31b and the head part 33 can be displaced or twisted in the lateral direction. For this purpose, these elements 31a, 31b, 33 can be partially elastic or be arranged with appropriate joints on a central structure. The advantage of such a configuration is that in the event of a twisting movement of the occupant, the lumbar vertebra section 31a, the shoulder section 31b and the head part 33 follow this rotary movement and continue to support the occupant. The head part 33 can of course also be adjustable along the height axis Z and along the width axis. In FIGS. 11a and 11b it can also be seen that the shoulder section 31b has a section 31c which can be moved along the width axis Y from. This can be done, for example, by means of a guidance system. This efficiently supports a rotational movement of the occupant. The seats 2a, 2b can also be further Other functionalities that promote relaxation, such as a massage function, for example.

The seat arrangement 16 can furthermore comprise a service element 42. Such a service element 42 is shown in FIGS. 14, 16, 17 and 18 to 22. This service element 42 can serve as a shelf or table. This service element 42 is advantageously arranged on the body floor 101 such that it can be displaced via a guide system 43. This guide system 43 can be designed analogously to the rail system 15a of the seats 2a, 2b. Accordingly, a possible embodiment would be a rail system 15a, as shown in FIG. The service element 42 can be displaced into the center of the vehicle interior 3 during use, as shown, for example, in FIGS. 14 and 22. When not in use, the service element 42 can be moved to a storage area 44. In Figures 18 to 22 various possible arrangements of the service element 42 in the storage area 44 and a corresponding arrangement of the guide system 43 are Darge provides. Thus, the storage area 10 of the service element 9 can be provided on the right front side of the vehicle 100. This would usually correspond to the side of the passenger seat. The storage area 44 of the service element 42 can also be provided on the left rear side of the vehicle 100. The storage area 44 is thus arranged behind the driver's seat. These representations relate to vehicles that are intended for so-called right-hand traffic. For vehicles that are intended for so-called left-hand traffic, the pages described would have to be reversed. The service element 42 can comprise a vertically extendable table section, as can be seen in FIGS. 6, 19, 20 and 21. This table section 11 can be extended or retracted along the double arrow 12 in FIG. 6 by an actuator (electric, hydraulic, etc.). The table section 45 furthermore comprises two side regions 45a, 45b, which can be moved in the lateral direction towards the respective seats 2a, 2b. This is indicated in FIG. 17 with the aid of double arrows 45c. The side areas 45a, 45b can be laterally displaceable by means of a rail system. The service center 42 further comprises a storage section 45d for electrical devices, such as smartphones, etc. This storage section 45d can be designed in such a way that a charging function, preferably wirelessly, is provided for the electrical devices. Furthermore, a storage area can be provided in which providers can make certain gift items available, for example in the case of a rental car. The at least one suspension / damping module 9 advantageously comprises an energy recovery device 17, by means of which kinetic energy from multiaxial vibrations of the vehicle seat 2 can at least partially be converted into electrical energy. This electrical energy can be fed into the on-board system. Due to the individual adaptability of the suspension / damping module 9, the occupant can determine for himself how much he would like to be cushioned in order to counteract the kinetosis. If the setting is selected so that the potential cushioning option is not fully used, the remaining energy that is generated can be recovered by the energy recovery device 17.

Due to the great freedom of movement of the occupants, it is advantageous that the lighting device is controlled as a function of the position and / or orientation of the occupant and / or of the position and / or orientation of the head of the occupant. For this purpose, the corresponding internal sensor devices 22 are provided, which detect the position and / or orientation of the occupant and / or the position and / or orientation of the occupant's head. The first control device 5 then modifies at least one lighting parameter based on the sensor data of the internal sensor device 22, which detects the position and / or orientation of the occupant and / or the head of the occupant in the vehicle interior. The individual lighting for the occupant can thus be effectively adapted to the movement of the occupant in the vehicle interior.

Furthermore, at least one projection device 46d can be provided which projects information data onto at least one projection surface, with a plurality of projection surfaces being provided, with the at least one projection device depending on the position and / or orientation of the occupant and / or the head of the occupant the first control device is controlled so that the projection takes place on that projection surface which is best visible to the occupant.

Furthermore, at least one display device 46d can be provided for displaying information data. Such information data can be status data of the vehicle, such as speed, time, arrival time, engine parameters, navigation information and any other information data. Preferably, depending on the position and / or orientation of the occupant and / or depending on the position and / or orientation of the head of the occupant, the information data that is best visible to the occupant is displayed on the display device. For this purpose, the first control device records the data of the corresponding the internal sensor device 22 and calculates which display device is the one that is best visible to the occupant based on its orientation and / or position, or the orientation and / or position of the head of the occupant. The display device can be a display device or just a projection surface onto which at least one projection device 58 projects the information data for viewing. Accordingly, a plurality of projection surfaces is provided, which are best visible to the occupants. This activation is preferably limited to the driver / supervisor of the vehicle. In the case of a classic alignment with a view through the windshield, a first projection surface or the first display device is arranged in an area below the windshield in which the usual armature displays can also be expected. If the occupant turns away from this position / orientation, the information data can be displayed on a nearby display device / projection surface. The at least one display element or the at least one projection device can preferably also be modified with regard to the lighting parameters. Accordingly, the display device can also be modified with regard to the lighting parameters (light intensity, light color, etc.).

The system 1 comprises an interface device 18, which is connected to the first control device 5 in terms of signaling. The at least one setpoint / limit value or setpoint / limit value range can be entered and / or modified by means of the interface device 18. Likewise, modification parameters, ie the degree of modification (a stronger or weaker modification of the comfort parameters) of the comfort parameters can be entered and / or modified by means of the interface device 18. Furthermore, the control of the at least one convenience device 6 can be specified by means of the interface device 18. The occupant can specify which comfort devices 6, ie which type of comfort devices 6 or which comfort devices are controlled at a specific location in the vehicle interior. The suppression of symptoms of motion sickness varies from person to person. Depending on the individual's feelings, a change in a certain comfort parameter can have a more effective effect on an occupant than another. The occupant can use the interface device to select which comfort parameters are to be modified and to what extent. The occupant can accordingly select any combination of comfort parameters that is favorable or effective for him and can determine the degree of modification. Of course, the at least one comfort parameter can be set manually by means of the interface device 18. The occupant can therefore adjust the comfort parameters manually at any time. For this purpose, an input / output device 19 is connected to the interface device for signaling purposes. This connection can be a wireless connection or a wired connection. The input / output device 19 can be, for example, a control panel, a touch screen or the like. It would also be conceivable that the input / output device 19 is a smartphone, a tablet computer or a laptop. The wireless connection could be an RFID connection, an NFC connection, a WLAN connection, a cellular connection or a similar connection. The occupant can comfortably carry out the setting to be made by means of such an input / output device 19.

Furthermore, it is advantageous that the modification of the comfort parameters takes place on the basis of predetermined profile data of an occupant. The profile data are matched to an occupant and advantageously include preferences of the occupant with regard to his individual comfort experience. The profile data can thus include the preferred at least one setpoint / limit value or setpoint / limit value range and / or the modification parameters and / or the preferred control of certain comfort devices 6 and / or the preferred modification of comfort parameters. The profile data or the profile can / can be activated by an occupant. The first control device 5 is accordingly made available settings relating to the comfort parameters. The occupant therefore no longer needs to make any further settings or inputs. The profile data can be stored in a memory device 8. It would also be conceivable for the profile data to be stored in the input / output device 19, for example a smartphone. This profile data can then be called up automatically by the interface device 18. Thus, when using different vehicles, the corresponding settings can be automatically transferred to the respective first control device 5. It would also be conceivable for the occupant to be able to select certain standardized modes which include corresponding presettings.

Another factor which, on the one hand, may prevent or reduce motion sickness is the air conditioning in the vehicle. An individual adaptation of the air conditioning to the individual occupants can continue to make a corresponding contribution to the feeling of comfort. Accordingly, at least one comfort device 6 is designed as an air conditioning device 23, the modifiable comfort parameters including air conditioning parameters. Air conditioning of the vehicle 100 is implemented, for example, by an air flow entering the vehicle 1. Accordingly, the air conditioning parameters include various air flow parameters. Such air flow parameters can be, for example, the amount of air introduced, the direction of flow of the air flow, the temperature of the led to be air and relative humidity. Such air conditioning can be individually adapted to an occupant in terms of a first control device 5. The air flow enters the vehicle through air inlet devices 48. These air inlet devices 48 can be flat and have a plurality of openings through which an air stream can pass. The air inlet devices 48 are located in the front area of the vehicle. Furthermore, it would be conceivable for air inlet devices 48 to be provided in the side regions of the vehicle. Cumulatively or alternatively, air inlet devices 48 are provided in the ceiling area and / or the floor area of the vehicle 100. Some conceivable seat arrangements for vehicles are shown in FIGS. The air inlet devices 48 are only indicated schematically here. It would be conceivable, for example, that a large part of the ceiling area or the entire ceiling area is equipped with one or more air inlet devices 48. It is advantageous if the air conditioning can be carried out individually for each occupant. An individual air flow can be directed into the area of a seat 2, 2a, 2b.

At least one comfort device 6 can be designed as a scent generating device 26, the modifiable comfort parameters including scent parameters. In order to suppress travel sickness, a targeted release of certain fragrances and / or aromas can preferably also be advantageous. Such scents can, for example, have a calming effect or suppress any nausea. The scents and / or aromas can be introduced into the individual air flow by a scent generating device 26. Alternatively or cumulatively, a scent generating device 26 for releasing scents and / or aromas can release the corresponding scents or aromas outside of the individual air flow into the vehicle interior 3. It can be of advantage if the fragrances and / or aromas released are combined with other countermeasures to suppress travel sickness. Accordingly, a reduction in the temperature of the air flow, which is intended to ensure a refreshing impression, would also be underlined by a corresponding scent or a corresponding aroma, which has an equally refreshing effect.

An important factor related to motion sickness is the ambience in the interior of the vehicle. For this purpose, the color of the interior can be designed in such a way that it conveys an impression of security and directs the eye to important elements by working with light and dark, color-coordinated tones. Haptic properties support the functionality of the elements, soft for the body's own support zones, smooth for the cladding and sturdy for storage. To improve the ambience in the vehicle interior, at least one fog display or fog display device 28 or also called a “fog curtain” can be provided in the vehicle interior. Such a fog display device 28 conveys an aerosol, ie a mixture (dispersion) of solid or liquid particles in a gas, for example air, at a fixed location in the vehicle interior 3. Such a fog display device 28 can create a particularly pleasant ambience in the vehicle 100. It also has the advantage of not being fragile. Furthermore, the space occupied by the fog display device 28 can simply be used for other purposes by switching off the fog display device 28. The fog display device 28 can be operated individually or it can also be assigned to the lighting device 46 and controlled on the basis of the lighting parameters.

The fog display device 28 can be arranged in a rear region of the vehicle 100, as shown in FIGS. 14 and 24. However, other positions would certainly be conceivable to arrange the fog display device 28 in the vehicle interior 3. It could, for example, be arranged in the middle of the vehicle interior 3 or in the front area of the vehicle interior 3. Furthermore, it is conceivable to arrange several fog display devices 28 in the vehicle interior 3. A fog display device 28 can be implemented in different ways. An aerosol, ie a mixture (dispersion) of solid or liquid particles in a gas, for example air, or a fog-like medium is used to produce a preferably semitransparent projection surface. An image can then be generated on this surface by means of at least one projection device. Such a projection can generate a two-dimensional or a three-dimensional image. The projection device can be a laser projection device or some other optical projection device. Such a mist-like medium consists of particles which preferably have a size of a few 10 micrometers to a few 100 micrometers. These particles can be, for example, water particles. Of course, other suitable particles are also conceivable. The use of dry ice (C02) would also be conceivable. According to a preferred embodiment, the particles are preferably injected into a laminar air flow which extends along the projection surface. Possible configurations of a fog display device 28 are shown in FIGS. 23a, 23b and 23c. According to an embodiment according to FIG. 23 a, an air flow generator 49 generates the corresponding air flow 50. This is brought into the projection space 52 provided via a delivery device 51 which has corresponding outlet openings. An injection device 53 injects the corresponding aerosol 54, or the corresponding particles 54, into the air stream 50. Below the dispensing device 51 a suction device 55 is provided, which advantageously comprises a recovery device, by means of which the particles can be recovered and fed back to the injection device. The delivery device 51 can be designed in such a way that the width of the air flow 56 can be varied. A rather small width can cause a higher density of the particles, as a result of which a sharp image can be generated by means of the projection device. If the width is increased, color or light effects can be generated which have a positive effect on the ambience in the vehicle interior 3. For this purpose it can also be provided that the air flow is not laminar, but rather comprises an air vortex. The outlet openings could, for example, be controlled in such a way that they are oriented at an angle. A helical air flow could also be provided. The generation of the air flow and the suction power can be coordinated in such a way that no or only a few particles emerge from the projection surface 52. However, the generation of the air flow and the suction power can also be coordinated in such a way that particles, for example water particles, enter the vehicle interior. This can have a positive influence on the air quality in the vehicle interior 3. It would also be conceivable that certain fragrances or aromas are mixed into the air flow by the injection device 53 and thus function as a fragrance generating device 26.

In the embodiment according to FIG. 23 b, the dispensing device 51 is designed in such a way that these two disk-like air flows, so-called air shields 57, are generated by the air flow generator 3. The air shields 57 extend along the entire height and the entire depth of the projection space 52. However, they are spaced apart from one another along the width of the projection space 52, so that a space is created. The aerosol or the particles 54 are introduced into this intermediate space. The gap here has an advantageous width in a range between 10 mm and 300 mm. As a result, a very high particle density can be generated in the interspace, as a result of which a sharp image can be generated by the projection device. In the embodiment according to FIG. 23c, no suction device is used. The particles are released upwards by the release device 51. Air shields 57, which enclose the aerosol 54, are also preferably provided here. The fog display device 28 would also be conceivable in such a way that it can function as a tangible user interface, a so-called “tangible user interface”. For this purpose, objects that can be moved by the user, for example, can be introduced into the air flow. The corresponding movement can then be interpreted as a corresponding input. Alternatively or cumulatively, a gesture recognition voltage device may be provided in the fog display device 28. A corresponding input can then be made using gestures. The delivery device 51 and / or the suction device 55 can also be arranged in the vehicle via a roll compensation device and / or a vibration compensation device. Such devices can compensate for external influences such as vibrations or fluctuations caused by cornering and a possible disruption of the air flow 50 can be prevented. For this purpose, suspension and / or damping systems or also gyroscope arrangements can be conceivable.

The fog display device 28 can serve as a display, for example to show pictures or films. For example, vehicle data, navigation data or other information can also be displayed. The fog display device 28 can also be used to create an ambience, for example by introducing certain smells or aromas into the vehicle interior 3 or by certain light / color effects which may have a detrimental effect on the occupants.

The system 1 can also include an entertainment facility 27. Such an entertainment facility can provide games, films, etc. The entertainment device 27 can be connected to a display, for example with the fog display device 28. At least one comfort parameter can preferably be modified on the basis of a signal from the entertainment device 27. Interactive games can thus be carried out, with one or more seat position modules 10 being controlled, for example, in order to improve the gaming experience.

A combination of comfort devices 6 is advantageously activated, or a combination of comfort parameters is modified. The comfort experience for the occupant is thus maximized. In addition, the symptoms of motion sickness can be prevented or minimized. Such a combination is an effective and unique countermeasure to reduce motion sickness so that automated travel can be experienced without nausea. The occupant can specify an individual weighting of the possible combinations depending on their preference. Such a setting can be saved in the individual user profile already described.

FIG. 3 shows an overview diagram which describes the present system. The physical interactions are represented by a solid line and the transmission of information by a dashed line. The circumstances that arise such as Road conditions, driving-related conditions or weather-related conditions cause certain disruptions. These disruptions affect the vehicle 100 or a specific state in or on the vehicle 100. These disruptions affect the inferior of the vehicle, ie the occupants. These disturbances are detected by the at least one sensor device 4. The at least one sensor device 4 also detects the circumstances in the vehicle interior 3 (inferior). Based on the sensor parameters, the first control device controls at least one comfort device 6, for example a vehicle seat setting device 7, an air conditioning device 23, a lighting device 24, a sound device 25 and modifies the corresponding comfort parameter. The respective occupant can make the (pre-) settings through the interface device. The preferred comfort settings can be made by inputting the driver / front passenger (interface device). Certain comfort modes can also be selected by the occupant (e.g. standard, memory, preferred, dynamic, neutral).

Also all malfunctions that originate from the cabin, the body, the chassis, the upcoming road geometry and / or the weather conditions, as well as all events originating from the driver / passenger that affect the driving speed, acceleration and braking of the vehicle , are taken into account by the first control device. Not only disturbances, but also data from sensors that record the condition of the roads, the vehicle angular speed and acceleration, the head position of all occupants at all times, thermal cockpit interior data and the artificial horizon, which are parallel to the above-mentioned human and disruptive Input collected and processed. All these inputs lead to a comprehensive algorithm that controls visual / haptic / tactile and acoustic signal actions, events that influence the perception of the driver and passengers and thus well-being and comfort. For example, the ambient lighting 24 in combination with LED strips 24 can keep the artificial horizon 47 permanently independent of the movement of the vehicle body. The same procedure can be applied to the air outlets 48 which follow the head position and change the direction of the air depending on the disturbances. The main objective of the suspension unit 7 is to reduce the low-frequency vibrations that affect the driver through vehicle movement and thus prevent the mismatch between visual and vestibular human sensors, which has been defined as one of the main causes / effects of kinetosis. In addition, the algorithm can be programmed in such a way that the driver / passenger can play interactive games and experience playful effects with a dynamic sitting posture. In addition, the control algorithm Must control the multi-axis suspension so that the weight and inertia of the occupant can be converted into recovered energy at the level of the suspension under the seat 2, 2a, 2b.

The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention, provided that they are new to the state of the art, individually or in combination. It is further pointed out that features have also been described in the individual figures which can be advantageous in themselves. The person skilled in the art immediately recognizes that a certain feature described in a figure can also be advantageous without the adoption of further features from this figure. Furthermore, the person skilled in the art recognizes that advantages can also result from a combination of several features shown in individual or in different figures.
