Method for controlling a first and a second vehicle functionality for acting on a vehicle occupant while driving in a vehicle

The present invention relates to a method for controlling a first and a second vehicle functionality for acting on a vehicle occupant while driving in a vehicle. It also relates to a vehicle with a first and a second vehicle functionality for acting on a vehicle occupant while the vehicle is in motion.

When driving a vehicle, the driver and possibly other vehicle occupants should be exposed to the least possible stress in difficult traffic situations and under strenuous circumstances. This improves his ability to respond to challenges in accordance with the rules and with maximum security and to drive the vehicle safely. Driving comfort is also improved.

Systems are known in which the driver can call up certain comfort functions in the vehicle that can create a stimulating or relaxing feeling.

The present invention is based on the object of providing a method of the type described at the outset and a vehicle through which the prerequisites for particularly safe and pleasant driving behavior are ensured as simply and flexibly as possible when driving the vehicle in a wide variety of contexts.

According to the invention, this object is achieved by a method with the features of claim 1 and a vehicle with the features of claim 10. Advantageous refinements and developments result from the dependent claims.

In the method according to the invention for controlling a first and a second vehicle functionality for acting on a vehicle occupant while driving in a vehicle, driving situation data relating to the trip are recorded and a mood program is determined as a function of the recorded driving situation data. A program suggestion display is generated and output, which includes a graphic representation assigned to the mood program. It will be a Confirmation action of a user is recorded and the mood program is activated as a function of the recorded confirmation action of the user. The first and second vehicle functionality are activated in the activated mood program.

The mood program is advantageously proposed proactively if it can be used sensibly in a specific context of the journey and the needs of the user can be taken into account as early as possible.

The effect of the vehicle functionalities on the vehicle occupant, for example a driver of the vehicle, takes place in particular indirectly by influencing an environment in the vehicle interior that is perceptible to the senses for the vehicle occupant. Furthermore, there can be a direct effect on the vehicle occupant. To this end, various devices can be activated or deactivated or set.

In one embodiment of the method according to the invention, the first and second vehicle functionality include ambient lighting, a massage device of a vehicle seat, an air conditioning device, a media playback device and / or a window regulator. Other devices and functionalities of the vehicle can also be included. As a result, the environment in the vehicle interior can advantageously be influenced particularly comprehensively.

In the mood program, the first and second vehicle functionality are activated or deactivated or set in a specific combination and possibly with a specific time sequence and / or duration. An atmosphere program therefore includes, in particular, an automatically controlled “choreography” of various vehicle functionalities.

By activating and deactivating or setting the mentioned functionalities, parameters in the vehicle interior in particular are influenced which have an effect on the vehicle occupants. Such an effect can be perceived through seeing, hearing, smelling and feeling, and other sensory perceptions can also be addressed, such as temperature perception. This creates a certain mood in the vehicle interior, which has an effect in particular on the physiological condition of the vehicle occupant. For example, the ambient lighting can be used to create lighting of a certain brightness, color and dynamic in the vehicle interior. A massage device in a vehicle seat can massage the user sitting on it and thereby relieve or prevent muscle tension. An air conditioning device can create a warmer or colder room climate, generate an air flow by means of a fan and, if necessary, also create a scenting of the indoor air. Furthermore, a media playback device can be used for playing background music or background noises. In addition, a window lifter can be operated to open or close a window and accordingly control the exchange of air between the interior and exterior and let in or block external noises. All of these functionalities can affect the well-being and mood as well as physiological characteristics of the user and, for example, stimulate, calm, relax or contribute to a concentrated state of mind.

In a further development of the method, the mood program is set up to exert a calming or an invigorating effect on the vehicle occupant. Furthermore, other effects can be exerted, in particular physiological effects on the vehicle occupant. As a result, an influence on the vehicle occupant that is adapted to the context of the journey can advantageously take place in a particularly simple manner.

In a further embodiment, activating the first and / or second vehicle functionality includes setting a functional parameter. In particular, a set value of the functional parameter is changed in the process. As a result, the vehicle functionalities can advantageously not only be switched on or deactivated, but the activity of already active functionalities can be adapted in the desired manner by changing a functional parameter.

Such a functional parameter can relate, for example, to a color scheme, with at least one lighting device and a display device of the vehicle being able to be controlled as a function of the color scheme. In this way, for example, the colors used for ambient lighting are matched to the colors of an output unit, for example in the case of the center display or an instrument cluster of the vehicle.

In particular, the first and second vehicle functionality act through physiologically effective mechanisms to trigger a specific biological or physiological reaction of the To evoke or support vehicle occupants. For example, certain light colors, intensities and movement patterns, certain sounds and / or temperature profiles can lead to physiological reactions, in particular in the case of a combination of different stimuli, with a stimulating or calming effect on the vehicle occupant.

In the method, the action on the vehicle occupant is controlled during a journey, wherein the journey can include not only the period of movement of the vehicle from a starting position to a target position but also other periods of time, such as all times between getting in and out of the vehicle occupant and, if necessary, stops in one position, for example for charging an energy storage device.

The driving situation data recorded in the method are formed in such a way that information about a context of the trip and / or a driving situation or about a mood or physiological condition of the vehicle occupant emerges from it. The information can relate to both a current and a forecast state. In particular, the driving situation data relate to a mood of the vehicle occupant at the current or future point in time. For example, driving situation data are recorded in such a way that indications of a stress-inducing, exhausting, tiring or disturbing driving situation can be taken.

In one embodiment, the driving situation data include route planning data of a navigation system, traffic data, weather data in the vicinity of a route being traveled, operating data of the vehicle, biometric data of the vehicle occupant and / or calendar data. In this way, the driving situation can advantageously be assessed particularly precisely and the mood program can be determined particularly appropriately.

The route planning data of the navigation system relate, for example, to parameters for planning a route, for example a time duration or a spatial length of the planned route, a start and destination position and / or information about routes traveled, for example different types of roads. Furthermore, information about the surroundings of the planned route can be included, for example points of interest or special features in the surroundings.

The traffic data relate, for example, to a traffic density or the behavior of vehicles and other road users in the vicinity of the vehicle. The traffic data can be determined on the basis of and / or from environmental data recorded in the surroundings of the vehicle other facilities, for example as traffic jam or traffic reports that are recorded via radio or a digital network. Similarly, the weather data can also be recorded by the vehicle's own sensors or received by other devices. In particular, weather influences are included that affect the driving conditions when traveling on a route, such as wetness, ice, snow or fog. The operating data of the vehicle can relate, for example, to an operating state, a speed and / or an acceleration of the vehicle; In this case, in particular, the vehicle's own sensors are used for detection.

In particular, physiological parameters are recorded as biometric data of the vehicle occupant, in particular the driver of the vehicle, such as a pulse or indications of a degree of concentration or fatigue, such as eye movements or activity of the eyelids. The biometric data is recorded, for example, by a unit for observing the vehicle occupant, for example by means of a camera, or by another unit, for example a device worn on the body for recording physiological data, such as a fitness bracelet or a smart watch.

Calendar data can for example be recorded by a personal mobile device of the vehicle occupant coupled to the vehicle and relate, for example, to appointment data about past, current and upcoming appointments, including, for example, location and time information as well as information about other participants. This information can be used, for example, to determine a stress level of the vehicle occupant at a specific point in time or to determine times at which the vehicle occupant is to be stimulated or calmed.

The mood program can be determined, for example, by selecting from a selection of predetermined mood programs or by dynamically generating a mood program adapted to the context of the journey. This means that a mood program or a plurality of them can already be predefined and selectable. Furthermore, the vehicle functionalities can be selected and settings determined to generate the mood program; For this purpose, the functionalities themselves as well as the settings and parameters assigned to them are determined. Furthermore, the sequence and time structure of the mood program can be determined during generation.

The mood program is designed in particular in such a way that it is suitable for the driving situation and / or the mood or the physiological state of the To influence vehicle occupants at a specific point in time in such a way that an approximation of a specific target state or a predetermined target variable is achieved. The target state or the target variable relates in particular to a certain physiological parameter of the vehicle occupant, for example a stress level or a measure of his or her fatigue or alertness.

In a further embodiment, there is a specific time interval between the activation of the first vehicle functionality and the activation of the second vehicle functionality. As a result, the vehicle functionalities can advantageously be activated, deactivated or set in a certain “choreography” in such a way that they do not start or end at the same time, but rather that they act on the vehicle occupant one after the other.

For example, the lighting of the interior, in particular ambient lighting, is first adapted, for example in terms of its intensity and / or a color scheme. Then, about a few seconds later, output of certain music is activated and / or a volume of the output is adjusted. Again offset by a few seconds, a massage is started by an active vehicle seat. The air conditioning of the vehicle can also be activated at a time offset from the functions mentioned or its settings can be changed. The vehicle functionalities can also be activated, deactivated or reset several times during the course of the mood program, for example to calm the vehicle occupant at the beginning of the mood program and reactivate or reactivate him later within a certain period of time before the mood program is automatically terminated to wake up.

In the process, a program suggestion display is generated and output. This includes a graphic representation, which can include, for example, a written representation and / or a symbol. The output takes place in particular on a central display on a dashboard of the vehicle. It can also be output by means of another display device, for example in the instrument cluster or on another display, or by means of a display from the field of virtual reality (virtual / augmented reality), for example by means of a head-up display.

The output can take place in particular by means of a graphical user interface in which different displays can be output in a hierarchically structured sequence. In particular, there is a so-called start screen at a highest hierarchical level provided, also called homescreen, from which other menus and / or program views can be called. In particular, the start screen includes a content and geometric division into various logical program contexts, for example by means of windows or widgets. In this case, contents that belong together in terms of content or program logic are output within a specific sub-area, such as display and control elements of a specific program or an individual instance of a program or an application. The home screen can include, for example, a container widget, within which system messages, such as the program suggestion display, are output. The output can alternatively or additionally take place in a different way, for example by means of a pop-up in which a graphic representation appears on the display area and superimposes an existing representation.

In particular, the confirmation action comprises an actuation of a switching element, for example a button on a touch-sensitive surface, an implementation of a gesture or a voice input. The detection can take place in a manner known per se. For example, when the program proposal display is output, an actuatable button is generated within a graphical user interface, the actuation of the button then being recorded as a confirmation action.

In particular, the mood program has a certain total duration, after the expiry of which, for example, the properties and settings set and / or activated before the start of the mood program are set for the vehicle functionalities. Furthermore, it can be provided that the mood program is repeated periodically until the end of the total duration. The total duration can be a predetermined property of the mood program, but it can also be designed as adjustable parameters of the mood program, whereby the timing of the mood program is changed by setting the total duration so that the sequence of the mood program extends over the set total duration, for example by appropriately scaling individual time sequences within the mood program.

In one embodiment of the method, while the mood program is activated, a sequence display is generated and output. The progress display includes a graphic activity display element, the graphic activity display element including a display of a remaining time, in particular as an absolute time value, or a progress progress, in particular as a relatively or percentage time value or as a progress bar. As a result, a user can advantageously easily see how long the Execution of the tuning program is already ongoing and when the end of its duration is reached.

As an alternative or in addition, the graphic activity display element can comprise an element which displays the activity of the mood program itself, for example a pulsating or otherwise animated object, through which, however, no remaining running time is displayed.

In a further embodiment, the sequence display is formed in such a way that when the first or second vehicle functionality is activated, an activation element that is assigned to the first or second vehicle functionality is output at least temporarily. The user can thereby advantageously record and monitor the sequence of the mood program particularly well.

The activation element can be designed, for example, alphanumerically or as a graphic symbol. For example, it can include a text message through which the activation of the respective vehicle functionality is output. The activation element can also be output when a setting of a vehicle functionality is changed. The activation item can be faded in, gradually instead of suddenly appearing on the display, and it can be faded out at a later time, gradually disappearing. Similarly, when deactivating a vehicle functionality, an analog deactivation element for the respective vehicle functionality can be displayed in order to provide feedback on the deactivation. The activation element can be displayed for a specific display duration after the activation or deactivation or setting of the vehicle functionalities.

Interaction options can also be provided during the course of the mood program. In particular, at least one control element is provided that can be displayed during the process and on the basis of which a user can make inputs in order to influence the process of the mood program or to activate, deactivate or set at least one of the vehicle functionalities. For example, the sequence of the mood program can be paused, in which case, in particular, a further input for continuing or ending the mood program can then be recorded. Furthermore, for example, an acoustic output can be stopped or changed, for example with regard to the volume or the selection of a reproduced media file. In a further development, an operating intention of a user is recorded and the sequence display is changed as a function of the recorded operating intention in such a way that at least one operating element for recording a one-part operating action for the first or second vehicle functionality is displayed. As a result, the user can advantageously be provided with comprehensive operating options as required, while the operating element is otherwise not visible.

The operating intention can be detected, for example, on the basis of an actuation object approaching an actuation element, for example on the basis of a finger approaching a touch-sensitive surface, such as a touchscreen. This detection can take place in a manner known per se, for example by means of a capacitive sensor or by means of a light barrier. An operating element of the type explained above for interacting with the sequence of the mood program is displayed in particular after the intention to operate has been detected.

The vehicle according to the invention with a first and a second vehicle functionality for acting on a vehicle occupant while the vehicle is traveling comprises a detection unit which is set up to detect driving situation data relating to the trip, and a control unit which is coupled to the detection unit and is set up to to determine a mood program as a function of the determined driving situation data and to generate a program suggestion display. The program suggestion display includes a graphic representation assigned to the mood program. It also includes a display unit which is set up to output the program suggestion display. The acquisition unit is also set up to acquire a confirmation action by a user. The control unit is also set up to activate the mood program as a function of the confirmation action by the user and to activate the first and second vehicle functionality in the activated mood program.

The vehicle according to the invention is designed in particular to implement the method according to the invention described above. The vehicle thus has the same advantages as the method according to the invention.

The invention will now be explained on the basis of exemplary embodiments with reference to the drawings. Figure 1 shows an embodiment of the vehicle according to the invention,

Figures 2A to 2J show displays that can be generated in an embodiment of the method according to the invention,

FIGS. 3A and 3B show further displays that can be generated in an exemplary embodiment of the method according to the invention, and FIG. 4 shows an exemplary embodiment of ambient lighting in a vehicle interior.

An exemplary embodiment of the vehicle according to the invention is explained with reference to FIG.

The vehicle 1 comprises a detection unit 2, a control unit 3 and a touchscreen 4. The touchscreen 4 comprises a touch-sensitive surface 5 and a proximity detection unit 6. The detection unit 2 and the touchscreen 4 are coupled to the control unit 3. Furthermore, various vehicle functionalities 7 to 10 are coupled to the control unit 3, in the exemplary embodiment a media playback device 7, an ambient lighting 8, a massage device 9 and an air conditioning device 10.

An exemplary embodiment of the method according to the invention is explained with reference to FIG. This is based on the exemplary embodiment of the vehicle according to the invention explained above.

The acquisition unit 2 is set up in a manner known per se to acquire driving situation data about a journey currently being carried out with the vehicle 1. In the exemplary embodiment, the acquisition unit 2 accesses a navigation system for this purpose, which provides route planning data about the currently traveled or planned route. The length and duration of the route as well as the start and end positions are provided. The navigation system also records traffic data, such as traffic jam warnings, which are provided via a radio system. The acquisition unit 2 also acquires weather data in the vicinity of the route currently being traveled, in particular data on rain, fog and impending ice. Furthermore, operating data are recorded by means of sensors of the vehicle 1, in the exemplary embodiment the current speed. In the exemplary embodiment, biometric data of a driver are also recorded, these data being provided by a fitness bracelet that measures the pulse. Furthermore, the acquisition unit 2 accesses an electronic calendar of the driver and acquires appointment data with time information and position data. In further embodiments, the Detection unit 2 comprise an observation camera in the interior of the vehicle, which observes the driver and, in particular, detects indications that the driver is tired.

An assessment of the driving situation and the condition of the driver is carried out on the basis of the recorded data. A stress level for the driver is determined or estimated, which in the example is higher the longer the route takes, the denser the surrounding traffic, the more unfavorable the prevailing weather conditions and the closer the driver's appointments are. The recorded pulse is also taken into account. A mood program is now determined, a series of different predetermined mood programs being specified in the exemplary embodiment, from which the particular mood program is selected. In further exemplary embodiments, the mood program is regenerated or modified.

A program suggestion display is generated and output on the touchscreen 4. Such a display and the detection of a confirmation action are explained in more detail below with reference to FIGS. 2B and 2C. The program suggestion display indicates to the user that a specific mood program is suggested and can be carried out. The user is asked to confirm the activation of the mood program.

The confirmation action is detected by the touch-sensitive surface 5 of the touchscreen 4 and then the specific mood program is activated, that is to say executed. When executing the activated mood program, various vehicle functionalities 7 to 10 are activated one after the other or their settings are changed in such a way that parameters in the vehicle interior that can be sensed by the driver change. There are defined time intervals between the activation of the various vehicle functionalities 7 to 10 or between the changing of the settings for the vehicle functionalities 7 to 10. A total duration of the ... program is also defined. The vehicle functions 7 to 10 are suitable for creating a mood in the vehicle interior for the driver.

It is assumed below that the particular mood program is a relaxation program which is designed in such a way that the user experiences a calming effect as a result. However, the invention is not to such Mood program is limited, but an invigorating program or an mood program with a different effect can also be carried out, for example.

With reference to FIGS. 2A to 2J, displays are explained which can be generated in an exemplary embodiment of the method according to the invention. This is based on the exemplary embodiment of the vehicle according to the invention explained above.

FIG. 2A schematically shows the structure of a display 20 in which a start screen, also referred to as a home screen, is output. This is output on the touchscreen 4 when the vehicle 1 is started, for example, and can be called up again from other contexts by pressing a return button. The home screen particularly denotes an output arranged in a hierarchy of outputs at the highest hierarchical level, from which other outputs, which are assigned to individual applications of an operating system, for example, can be reached.

In the exemplary embodiment, the home screen comprises 4 widgets 21 to 24, one of which is designed as a container widget 21. In the exemplary embodiment, the container widget 21 is used to output system messages with changing contents, while the further widgets 22 to 24 can be assigned to fixed applications of the operating system, such as media playback, a telephone book or a navigation function.

FIG. 2B shows an enlarged view of the container widget 21 in a state after a proposal for activating an atmosphere program, in the exemplary embodiment a relaxation program, has been generated. It is therefore a program suggestion display within the container widget 21 with a text output 25, which specifies heavy traffic as the reason for the suggestion of the relaxation program and asks for confirmation of the suggestion, and a confirmation button 26. Widget 21 information about the current weather, this information only depending on the standard use of the container widget 21.

FIG. 2C likewise shows an enlarged view of the container widget 21 with a program suggestion display, which in this case, however, extends over the entire area of the container widget 21. Such a state is achieved in the example in that, starting from the case shown in FIG. 2B, the user requests an enlarged representation of the program suggestion display, for example by tapping the text output 25, or if so the method is carried out in such a way that the program suggestion display is always output over the area of the entire container widget 21. In particular, a display that fills an entire widget 21 to 24 of the display 20 is referred to as a “card”. In the case shown, functionality symbols 27 are also output which represent symbols for the vehicle functionalities 7 to 10. In the exemplary embodiment, the functionality symbols 27 are shown grayed out at this point as long as they have not yet been activated by the mood program.

In the case shown in FIG. 2D, the user has pressed the confirmation button 26 and thereby activated the proposed relaxation program. The display is changed so that a progress display 28 is now displayed, in the exemplary embodiment with a numerically specified time value that indicates the remaining time until the end of the total duration of the relaxation program, and with a progress bar, which here runs along an open circle. In the exemplary embodiment, the total duration is specified as 1 minute, but it can deviate from this in further exemplary embodiments and have about 10 minutes or a different duration. Furthermore, the functionality symbols 27 are still shown grayed out.

FIG. 2E shows a case in which the execution of the relaxation program has progressed further. As part of the execution of the relaxation program, the ambient lighting 8 of the vehicle 1 is activated and set. This activation or setting is indicated in the representation by an enlarged functionality symbol 29a and a text output 29a ', while the functionality symbols 27 are hidden.

In the case shown in FIG. 2F, the activation of the ambient lighting 8 is complete and, similar to the case shown in FIG. 2D, the sequence display 28 is displayed again with the functionality symbols 27, the functionality symbol 27 assigned to the ambient lighting 8 no longer being shown grayed out and is highlighted instead. This is shown in FIG. 2F by a border, but any graphic highlighting can be used.

In the case shown in FIG. 2G, the execution of the relaxation program has also progressed and, analogously to the case shown in FIG. 2E, an audio output by means of the media playback device 7 is activated and set. The display now includes a corresponding functionality symbol 29b and a corresponding text output 29b '. Analogously to the cases shown in FIGS. 2E and 2G, in the case shown in FIG. 2H, the massage device 9 or, in the case shown in FIG. 2I, the air conditioning device 10 are activated and set. The display comprises corresponding function symbols 29c, 29d and text outputs 29c ', 29d' at the respective times of activation or setting.

In the case shown in FIG. 2J, the end of the total duration of the relaxation program is finally reached, which is indicated by a completion symbol 30 with a completely filled progress bar. Furthermore, the display includes the functionality symbols 27, all of which are displayed activated in the exemplary embodiment.

Subsequent to the execution of the relaxation program, the vehicle functions 7 to 10 can be deactivated again or the parameters set before the relaxation program can be set again.

With reference to FIGS. 3A and 3B, further displays are explained which can be generated in an exemplary embodiment of the method according to the invention. This is based on the exemplary embodiments explained above. It is assumed that the relaxation program is running.

In the cases shown in FIGS. 3A and 3B, the

Proximity detection unit 6 detects that a finger of the user is approaching touchscreen 4. This is assessed as an operating intention and the display is changed in such a way that buttons 31, 32 are displayed, by means of which the user can make settings and influence the course of the relaxation program.

In the case shown in FIG. 3A, the ambient lighting 8 of the vehicle 1 has just been activated and the display includes the corresponding functionality symbol 29a and the corresponding text output 29a '. After the approach has been detected, a button 31 for pausing the currently executed relaxation program is displayed. By pressing this button 31, the user can inhibit the course of the relaxation program, the total duration of which does not continue to run. In particular, further buttons are then displayed which the user can press to continue or cancel the active mood program. In the case shown in FIG. 3B, the ambient lighting 8 and the media playback device 7 are already active, which is indicated by appropriately highlighted functionality symbols 27. In this case, the display also includes the progress indicator 28. After the approach has been detected, buttons 31, 32 are displayed, by actuating these buttons the user can pause the progress of the relaxation program or mute the audio output played in the background. In the exemplary embodiment shown here, actuation of the corresponding button 32 leads to the media playback being silenced in accordance with the relaxation program and instead the previously set media playback being continued.

In a further exemplary embodiment, a button is also output, similar to the case shown in FIG. 3B, by means of which the user can select a different media reproduction of the relaxation program. For this purpose, several different sounds are assigned to the relaxation program, for example, which are played in the background.

With reference to FIG. 4, an exemplary embodiment of ambient lighting in a vehicle interior is explained. This is based on the exemplary embodiment of the vehicle according to the invention explained above.

A display 41 is arranged in a vehicle interior of the vehicle 1, which in the exemplary embodiment comprises the touchscreen 4. Furthermore, vehicle seats 42, 43 and devices for ambient lighting 44 are located in the interior. In particular, these are arranged behind decorative elements and are suitable for indirectly emitting colored light into vehicle interior 40.

Further optional aspects of the method according to the invention are explained in more detail below. This is based on the exemplary embodiments explained above, which are supplemented if necessary.

Various vehicle and comfort functions are used when executing the relaxation program. These are intended to help calm the driver of vehicle 1 and / or other vehicle occupants in stressful situations during a journey. Furthermore, a user can be given an opportunity to relax while stationary, for example when an electric vehicle is charging. The relaxation program is proposed proactively after a stressful situation has been identified. Such Stress situations are recognized, for example, when there is a difficult traffic situation or when an increased stress level of the driver or another vehicle occupant has been recorded using biometric data.

In a proactive mode, in which the relaxation program is not actively called up by the user but is suggested by vehicle 1, the data from the sensors and functions present in vehicle 1 are aggregated in order to determine whether the driver is in a stressful situation. Possible sensor data are drowsiness detection, physiological sensors in the vehicle or via coupled external devices such as smartphones, fitness wristbands or smartwatches. Furthermore, a driving style can be analyzed, for example based on acceleration, braking and steering behavior or based on keeping in lane of vehicle 1. Furthermore, data on the driving situation and environmental data are aggregated, such as traffic density, environmental influences, weather, temperature or time-critical appointments in combination with navigation data in the driver's calendar. If a stressful situation is detected, the system recommends that the user carry out a relaxation program. In particular, this recommendation is generated in such a way that a possibly predetermined threshold value at which a warning is generated by a drowsiness detection, for example, has not yet been exceeded and thus in particular critical drowsiness or inattentiveness can be prevented before it occurs. If the current traffic situation does not allow it, the program can be put into a waiting state in order to be offered again at the next opportunity.

Furthermore, a manual mode can be provided in which the user can actively start the relaxation program by making an entry. Furthermore, a learning function can be provided, whereby it is recorded when a user actively calls up the relaxation program and which settings he makes in the program. The behavior and preferences of the user are learned on the basis of the active calls and additionally recorded data about the driving situation. Furthermore, the learning function can be used to adapt the program according to the behavior learned and the preferences of the user.

In the relaxation program, a “choreographed”, time-orchestrated and coordinated activation and setting of the vehicle functionalities 7 to 10 gradually creates a relaxed atmosphere for the driver or other vehicle occupants. The aim is to reduce an increased level of stress on the part of the user and to bring about a feeling of well-being. In addition, a graphic feedback is generated through which the user can record which Vehicle functionalities 7 to 10 are addressed by the relaxation program.

For example, a seat massage symbol indicates that a massage function is in use. A running timer shows how long the entire program will take. The user can also pause or end the program or mute an ambient sound. If music was set by the user before the start of the relaxation program, pressing a mute button 32 (“Mute”) during the relaxation program causes a return to the previous sound source.

In a stressful situation, for example in heavy traffic and impending traffic jams, the user is proactively suggested on the home screen to start the relaxation program. A corresponding display is shown above with reference to Figures 2B and 2C. The representation shown in the widget 21 can be shown enlarged, with a reduced icon overview showing which range of functions the program currently includes. Furthermore, the program can be started directly via the confirmation button 26.

After confirmation by the user, the relaxation program begins and, in particular, a timer 28 is displayed which shows the total duration and progress of the program.

If further functionalities 7 to 10 are activated, a temporary feedback is displayed with a corresponding functionality symbol 29a to 29d. This is followed by feedback on how far the relaxation program has progressed. Further vehicle functionalities 7 to 10 for the relaxation program are gradually started and corresponding feedback is generated and output.

When the relaxation program ends, a final screen is displayed, as shown for example in FIG. 2J, before the “card”, that is to say a full-screen display or an enlarged widget, closes again. In particular, the home screen is then displayed.

Furthermore, the proximity detection unit 6 can be used to detect an “approximate” state in which there is no intent to operate and no buttons are displayed within the widget 21, or an “approximate” state in which there is no intention to operate and buttons 31, 32 are displayed to display a pause button after starting the relaxation program or a "mute" button to deactivate an ambience sound. If the ambient lighting 8 is activated in the relaxation mode, the ambient lighting 8 changes from a preset color to the relaxation mode.

Indirect light, footwell light and lighting for the storage compartments in the doors and in the area of the center console are colored according to a relaxation color scheme; a color scheme of the display on the display 41 is colored accordingly.

For example, three different variants are provided: a “fireplace” mood with ambient light in red, orange and yellow tones, a “forest” mood with ambient light in green, blue and yellow tones and a “sea” mood with ambient light in Blue-green-white tones.

The indirect light that is generated by lighting below decorative elements in the interior of the vehicle 1 performs a harmonious movement and a periodic or irregular change in distribution, intensity and / or color, in particular a "wobble".

During the execution of the relaxation program, nature sounds can be output in the background by the media playback device 7, in particular to match a certain relaxation mode or to match the color scheme of the ambient lighting 8. For example, a "fireplace" mood can be linked to the crackling of fire, a "forest" - Mood with the twittering of birds and a "sea" mood with the sound of the sea. The user can in particular decide whether the background sound of the relaxation program should be played instead of a self-set media playback or whether a previously set music should continue to be played.
