Description

The invention relates to a configuration system for a vehicle interior of a motor vehicle.Many persons are entrusted with confidential data in professional context and must therefore often not handle these data in public places or vehicles. Many people, especially in Asian countries, use taxes. Particularly in the luxus segment of motor vehicles, business persons or known personalities are vehicle passengers. To protect data, it may be desirable to decouple the driver from looking into the passenger compartment.CN 118205505 A relates to a vehicle office system including: a table top disposed in an instrument panel and moving to a first preset position in response to an activation instruction for the vehicle office mode; an input device connected to the table top; and an execution module generating input contents according to the input instruction in response to the identification of the input instruction of the input device. This serves to improve convenience in office work in the vehicle for users who are required to carry office devices with them, and improves the experience of car use.It is an object of the invention to improve the operation of an occupant of a motor vehicle.The invention results from the features of the independent claims. Advantageous refinements and refinements are the subject matter of the dependent claims.A first aspect of the invention relates to a configuration system for a vehicle interior of a motor vehicle, wherein the configuration system is designed to activate, in response to a trigger signal, an office mode restricted to one or more occupants in the vehicle interior, and, with the activation of the office mode, adjust illumination in the region of the occupant, reduce a volume of multimedia contents played back in the region of the occupant or completely cancel or pause the playback of the multimedia contents, wherein the multimedia contents comprise at least entertainment contents and a voice playback of a navigation system of the motor vehicle, and adjust a parameter of a driving control and / or a chassis parameter for a calmer drive, and to filter audio information from one or more microphones which are suitable for capturing, discarding or mechanically filtering speech of the occupant on the basis of predefined data protection requirements.In order to facilitate a work of an occupant in the interior of the vehicle, the smoothest possible driving behavior is desired. When using driver assistance systems, acceleration, brake executions, cornering, passing processes are carried out as smoothly as possible, for example. In different driving situations, the vehicle remains quiet and even therein without abrupt movements or vibrations. This includes the vehicle responding in a damped manner to steering and acceleration commands in order to enable smooth and comfortable travel. The force transmission is preferably effected uniformly and without jerking movements in order to increase the driving comfort. The vehicle remains stable and quiet even under different road conditions. Unevenness on the road is effectively compensated for, which contributes to comfortable travel. The steering responds precisely and without undue effort to enable a relaxed driving experience.A technical implementation can be effected, for example, by activating one or more of the following known systems / assistants in office mode:A comfort mode: This driving mode optimizes the suspension and damping for a particularly smooth and comfortable travel. Steering is lighter and gas acceptance is smoother.Adaptive Damping System: This system continuously adjusts damping to driving conditions and style to ensure maximum comfort.an air suspension which automatically adjusts the vehicle level and compensates for unevennesses in the roadway in order to enable a smooth and comfortable journey.Active Distance Assistant: This system automatically keeps the distance to the vehicle traveling ahead and can relieve the driver in stop-and-go traffic.Active steering assist: assists the driver in keeping the vehicle in the lane by making smooth steering corrections.While the driver cannot see shared contents with the SAE level 2 or lower activated, the full office system is available with the SAE level 3 or higher. The mode can be activated manually or automatically, for example by detecting a laptop or a videoconferencing. Different user profiles allow for individual adjustment of the settings. During office mode, functions such as interior lighting, display brightness, and sun screen blinds, or others, are intelligently controlled to provide optimal conditions for video conferencing. Driving noise and other sources of interference are minimized to ensure an undisturbed working environment. A "not disturb" mode can be activated to block all incoming calls and interrupts. The system may also detect the mood of the occupant and take appropriate action to reduce stress, such as seat massage or sedative music.The office mode can be activated, for example, by a gesture, for example a hand movement, by a voice command to a voice assistant of the vehicle, haptically, for example by dragging / pressing on an operating element or switch or display, or automatically by artificial intelligence. Corresponding sensors in the vehicle interior can be used for this purpose, for example ultrasound, lidar, radar, camera. In particular, it is possible to detect via the vehicle cameras when an occupant operates a laptop or another mobile terminal, and / or that the occupant carries out a video conference or a telephone conference. Microphones and camera images in the interior of the vehicle may be used for this purpose. By learning habit through artificial intelligence, the vehicle may identify when to enable or disable office mode. The following possible habits are conceivable: in which persons the office mode must be activated (for example, when the call of a specific person arrives), at a specific time of day when a specific driver guides the vehicle.In office mode, in particular, the following actions can be carried out, alone or in combination with one another:activating interior lighting in bright white or yellow tones during video conferences of the occupant with the camera activated. Colored colors of the ambient lighting lead to coloring of the face and unattractive image transmission.Interior illumination is intended to contribute to optimum illumination of the occupant so that the subscribers receive a good image of them.turning on the roof lighting or other lamps in video conferencing with the camera turned on. The more lamps from different directions illuminate the face, the fewer shadows are seen in the face.The brightness of the displays is adapted in such a way that colors that are harmful to eyes are minimized at night and the brightness is automatically adapted to solar radiation during the day, so that the occupant recognizes representations on the display. When the office mode is active for the passenger, a private display mode is activated so that the driver does not see the contents of the passenger display. If the office mode is active for the driver and SAE level 2 or lower prevails, then the "display on displays" function is disabled for the driver so that the driver is not distracted. At SAE level 3 or higher, on the other hand, the function may be active and content may be displayed to the driver on the display.In the case of solar radiation, the roller shades are opened or closed, in particular on the window or rear window; all electrically controlled sun roller shades and the sliding roof are closed.All the panels which can be electrically shaded and the panoramic roof are activated in order likewise to minimize solar radiation. The sun position may be detected by cameras or calculated based on the GPS data. The direction of travel is assumed to be known and GPS data, time, position are present. In order that the roller blinds are not opened or closed at each curve, a route planned in the navigation system is taken into account. Actions are performed only when the vehicle does not change the rough direction for a longer time, thereby ensuring that the occupant is not disturbed by repeated opening and closing. For example, navigation routes are selected which have particularly few curves or routes which can be driven without a great stop and go.The radio / entertainment system is rendered quiet and filtered out during the transmission of the noises.Incoming calls to the driver are muted and displayed via the display. Should the call be accepted, the call is switched quietly and the tones for the passenger are minimized via frequency overlap.Driving noises are further minimized by frequency overlap.A voice assistant is made idle so that the driver can continue to act but the occupant is not disturbed in conversation with office mode.The volume of a navigation system is reduced or muted.a subwoofer in the trunk is deactivated.a chassis of the vehicle is adjusted in such a way that driving noises can be further minimized and the occupant is as far as possible not disturbed when a mobile terminal is manually operated.An automatic transmission is set at maximum comfort in order to minimize disruptive shifting processes and high engine speeds.Displays in the middle between front and rear banks can be lowered. This allows zone separation.Should there be partition walls that can rise up, they can also be activated.If the vehicle has a zone music system in which music is played individually per zone and cannot be heard by the other occupants, this can be activated. This makes it possible that the conversation of the occupant is not transmitted to an area of the driver using the office mode. The music, voice output of a navigation system, etc. do not have to be muted thereby.It is conceivable for the driver that further disturbing noises or frequency overlaps have been carried out in order to treat the conversation confidentially. If, for example, it is not a foreign taxi driver, but rather the individual chauffer, the system can be adapted in such a way that the driver's wishes are also taken into account and, for example, the music is not displayed. This is intended to ensure that the driver and occupant together have a pleasant journey in office mode. If it is not a video conference, but only a telephone call, this can be taken into account. This does not activate the roller blind or ambient lighting because the solar radiation does not have to be minimized or the face of the occupant should be optimally illuminated and transmitted.The intelligent office mode in the vehicle is designed in particular to ensure privacy when working in a mobile manner, in particular for persons working with confidential data. Protection for confidential data of the occupant in office mode can be achieved by not using conversation information of the occupant recorded via microphones in the interior of the vehicle for unwanted application and analysis purposes. It can thus be ensured that this data is handled confidentially without an occupant having to explicitly change data protection agreements.In the case of particularly important calls, the occupant can activate, in office mode, in particular a mode in which all incoming calls are not made. Radio, entertainment, voice output of a navigation system, etc. are muted. The driver can interrupt this mode for a specific time for specific systems / applications, in order to obtain the necessary information, for example, in the case of particularly complex turning processes. After a certain time (for example. 5 minutes) the mode is activated again. The "not disturb" mode is preferably terminated once the conference has been terminated.Furthermore, a detection of a mood state at the occupant can take place using the office mode. Another function may include the configuration system identifying the mood of the occupant in a video conference or a telephone conference, in particular an increased pulse from radar sensors, spots on the face from a camera in the interior of the vehicle, a loud or supervised speech, an increased breathing rate. By means of measures, the configuration system can attempt to enter into the passenger in a sedative manner, in particular by one of the following: activating a seat massage, seat ventilation or heating depending on habit, sedative music, indications via display, such as, for example, "if the driver is to care for coffee?", intelligent activation of the "non-disturbing" mode, adaptation of the ambient lighting and use of sedative hues. In certain calls, these activities can already be carried out preventively.It is an advantageous effect of the invention that data protection and confidentiality is improved. Persons working with confidential data are allowed to operate securely and privately in a vehicle without sensitive information being viewed or heard by others. Comfort and efficiency during vehicle work is increased by creating optimal conditions for video conferencing and telephone calls, such as by adjusting lighting and minimizing noise. Moreover, it is ensured that the driver of the vehicle is not distracted by shared contents or video conferencing by restricting access to such functions during driving. Stress reduction is achieved by detecting a current mood of the passenger and taking measures to reduce stress, such as seat massage or sedative music.In addition, a stress level of the driver of the vehicle can be lowered by activating measures such as a seat massage and a silencing ambient lighting in the vehicle. For this purpose, it is preferably analyzed when the driver is exposed to an increased stress level. With a specific color selection of the ambient lighting in the vehicle interior, the driver can be calmed, for example with a green tone which acts in a sedative, harmonic, safe, refreshing, compensating and natural manner, or with a blue tone which acts in a sedative, relaxing, concentration-promoting, trusted and clean manner, further with a violet tone which acts in a meaningful, luxurious, sedative and inspirating manner, and with a pink hue which acts in a roman, female, soft and sedative manner. In addition to the color change, alternatively or additionally a seat massage for the driver can be activated. In all cases, the aim is not to impair or increase the attention of the driver to the traffic and to reduce distraction of the driver for this purpose. In particular, it is important to prevent distraction of the driver by not ever encouraging the driver to look at image contents of a display. Accordingly, preferably, no contents of a telephone conference of an operating person in the interior of the vehicle are transmitted to a display in the range of vision of the driver.The driver should remain as quiet and relaxed as possible in order to be able to track the driving task as much as possible. For this purpose, a respiration frequency monitoring can furthermore be carried out, for example by means of interior radar. If its breathing frequency increases, this indicates an applied driver. Even if a louder speech of the driver is recognized, i.e. its speaking volume increases over time, which can be determined in particular by interior microphones, the above-mentioned measures can be initiated, such as the setting of the silencing color tones at the ambient lighting or the activation of a seat massage.In addition, the comfort during a conversation in a video conference is to be increased, the quality of the camera images and thus the video conference experience for the user is to be increased. If reading lights are used to improve a camera image of the occupant in office mode in order to ensure improved visibility for video conference participants, the light of the reading light can blind the driver of the vehicle. As a countermeasure, the light may be directed only to this occupant so as not to blind the driver or to contain the light.According to an advantageous embodiment, the configuration system is configured to move a partition from a hidden position to an extended position in response to the trigger signal. The system particularly disconnects the driver from the passenger compartment to protect data and increase comfort during conversations.According to a further advantageous embodiment, the configuration system is designed to adapt the position of a sun visor depending on incident ambient light in response to the trigger signal.According to a further advantageous embodiment, the configuration system is designed to drive down at least one display unit between front seats of the motor vehicle and rear seats or a rear bank of the motor vehicle in response to the trigger signal.According to a further advantageous embodiment, the configuration system is configured to generate anti-sound in response to the trigger signal in the vehicle interior outside an area of the occupant for which the office mode is activated, in order to make sound of conversations of the occupant outside an area of the occupant inobscible.According to a further advantageous embodiment, the configuration system is designed to detect mood of the occupant in response to the trigger signal and to adapt a vehicle interior parameter depending on the mood.According to another advantageous embodiment, the configuration system is configured to, when it is detected that the occupant for whom the office mode is to be generated is a driver of the vehicle, generate the trigger signal only when the vehicle is in a SAE 3 level or higher.According to a further advantageous embodiment, the configuration system is configured to, when it is detected that the occupant for whom the office mode is to be generated is a driver of the vehicle, only to be restrictedly configured to the office mode in response to the trigger signal if the vehicle is not in a SAE 3 level or higher.Certain contents are thus not available to the driver on account of the driver assistance system level. This relates in particular to a display of contents on displays in the field of vision of the driver, in particular contents divided during a video conference and a transmission of the camera data from other participants.The limited execution of the office mode is particularly available to the driver when: the mode for a zone associated with the driver's seat is activated, the driver himself has generated the trigger signal, and the vehicle is carrying at an ADAS system level 3 or higher. The unrestricted execution of the office mode, on the other hand, is generally available for all other occupants. In addition, execution of the office mode can be made dependent on an occupant occupying the seat in the respective area for which an office mode is desired.According to a further advantageous embodiment, the configuration system is designed to generate the trigger signal when a situation is automatically detected by the configuration system, said situation indicating a usefulness of the office mode.According to a further advantageous embodiment, the configuration system is designed to execute the office mode for a driver only if the trigger signal is assigned to the driver.Further advantages, features and details are evident from the following description, in which--possibly with reference to the drawing--at least one exemplary embodiment is described in detail.The following are shown: FIG. 1 : A vehicle interior with a configuration system according to an exemplary embodiment of the invention. FIG. 2 : shows a zone system for application to the configuration system according to an embodiment of the invention.The representations in the figure are schematic and not to scale.FIG. 1 shows a configuration system for a vehicle interior of a motor vehicle 1, wherein the configuration system is designed to activate an office mode restricted to one or more occupants in the vehicle interior, and, with the activation of the office mode, to adapt a lighting 2 in the region of the occupant, to reduce a volume of multimedia contents played in the region of the occupant or to completely cancel or pause the playback of the multimedia contents, wherein the multimedia contents comprise at least entertainment contents and a voice playback of a navigation system of the motor vehicle 1, and to adapt a parameter of a driving control and / or a chassis parameter for a calmer drive, and to filter audio information from one or more microphones 3 which are suitable for capturing, discarding or mechanically filtering speech of the occupant on the basis of predefined data protection requirements. The intelligent office mode configuration system in the vehicle 1 solves the problem of safe and comfortable work with confidential data during travel. It allows persons, such as business persons or known personalities, to work in a vehicle 1 without sensitive information being able to be seen or heard by others. In addition, it ensures that the driver is not distracted by shared contents or video conferencing to ensure the required safety during driving. The configuration system provides optimal conditions for video conferencing and telephone calls by intelligently adapting lighting, noise levels and other environmental factors. It offers an automated and user-friendly possibility of activating office mode based on the habit and needs of the occupant, and can recognize the mood of the occupant or driver and take measures for stress reduction.FIG. 2 shows schematically from the bird's eye view a division of the vehicle interior into the four zones I, II, III and IV. Only the driver can activate the office mode by himself in this exemplary embodiment. The office mode can, on the other hand, be activated for the other occupants by the driver or by the respective occupant himself. The office mode can be activated via a touch-sensitive display and / or voice control. The four zones into which the vehicle interior is logically divided from bird's eye view include a first zone I for the front left, a second zone II for the front right for the passenger, a third zone III for the rear left and a fourth zone IV for the rear right. Four choices are available to the driver through the four zones to activate office mode. Only three options are available to the other zones, zone I is not available to the driver. To activate the office mode, a trigger signal is used which in turn requires the following four preferred activation conditions:Activation condition 1: an identification is available for whom the office mode is to be activated and for which zone. This can be done via a display signal and / or voice control. Thus, if the office mode is sought for zone I, the following activation conditions 2, 3, 4 are also relevant:Activation condition 2: an identification is available as to who wishes to activate the office mode in the vehicle 1. This can be effected in particular via interior sensors, in particular via camera and / or radar and / or microphone and / or a display. If the activation takes place via a touch-sensitive display, the display signal of the corresponding display is detected.Activation condition 3: Is the seat occupied in this zone for which the office mode is to be activated? For this purpose, in particular a signal of the seat occupancy mat can be used for identification. If the seat is not occupied, the office mode is not activated; if the seat is occupied, the office mode is activated.Activation condition 4: Is the vehicle 1 in an ADAS system level THREE or higher? The ADAS system can be activated in particular by a combination of buttons on the steering wheel. Accordingly, it is possible to check whether the corresponding key combination on the steering wheel has been pressed and the corresponding signal is present in the driver assistance control unit.The following sequences are possible:First Exemplary Procedure:• The mode for zone I is activated;• The driver himself has activated zone I? If yes:• Vehicle 1 is in an ADAS system level THREE or higher? If yes:• Is the driver's seat occupied?
