Description

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. A confirmation action by a user is recorded and the mood program is activated as a function of the recorded confirmation action by 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 functions.

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 regulator can be operated to a To open or close windows and to control the exchange of air between indoor and outdoor space as well as to 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 in order to induce or support a specific biological or physiological reaction of the vehicle occupant. 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 environmental data recorded in the surroundings of the vehicle and / or received by other devices, for example as traffic jam or traffic reports that are recorded by radio or via 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 driving 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 such a way that it is suitable for influencing the driving situation and / or the mood or the physiological state of the vehicle occupant at a specific point in time in such a way that a specific target state or a predetermined target variable is approached. 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 certain 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, a so-called start screen, also called a home screen, is provided at the highest hierarchical level, from which other menus and / or program views can be called up. 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 another way, for example by means of a pop-up, in which a graphic representation appears on the display surface 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. In this way, a user can advantageously easily see how long the execution of the mood program has been going on and when the end of its duration has been 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 setting 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 intention to operate can be detected, for example, on the basis of an actuation object approaching an actuation element when a finger approaches 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 registration unit 2 is set up in a manner known per se to receive driving situation data about a current with the vehicle 1 to record the trip carried out. In the exemplary embodiment, the detection unit engages 2 To do this, go to a navigation system that provides route planning data about the route currently being traveled or planned. 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 registration unit 2 also records weather data in the vicinity of the route currently being traveled, in particular data on rain, fog and impending ice. Furthermore, by means of sensors of the vehicle 1 Operating data is recorded, 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. The registration unit also engages 2 to an electronic calendar of the driver and records appointment data with time information and position data. In further exemplary embodiments, the detection unit 2 comprise an observation camera in the interior of the vehicle, which observes the driver and in particular records 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, with one in the exemplary embodiment A number of different preset mood programs is given, 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 shown on the touchscreen 4th issued. Such an indication and the detection of an affirmative action are discussed below with reference to FIGS 2 B and 2C explained in more detail. 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 through the touch sensitive surface 5 of the touchscreen 4th and then the particular mood program is activated, i.e. executed. When the activated mood program is executed, various vehicle functions 7th to 10 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 functions 7th to 10 or between changing the settings for the vehicle functionalities 7th to 10 intended. A total duration of the ... program is also defined. The vehicle functionalities 7th to 10 are suitable for creating a mood for the driver in the vehicle interior.

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

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

2A shows schematically the structure of a display 20th , in which a start screen, also known as a home screen, is displayed. This is, for example, when the vehicle is started 1 on the touchscreen 4th output and can be called up again from other contexts by pressing a return key. 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 includes 4th Widgets 21st to 24 , one of which as a container widget 21st is trained. The container widget 21st serves in the exemplary embodiment to output system messages with changing content, while the other widgets 22nd to 24 Fixed applications of the operating system can be assigned, such as media playback, a telephone book or a navigation function.

2 B shows an enlarged view of the container widget 21st 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 21st with a text output 25th which states heavy traffic as the reason for the relaxation program proposal and asks you to confirm the proposal, and a confirmation button 26th . In addition, the container widget includes 21st Information about the current weather, this information only from the standard use of the container widget 21st depend.

2C also shows an enlarged view of the container widget 21st with a program suggestion display, which in this case, however, extends over the entire area of the container widget 21st extends. Such a state is achieved in the example by the user starting from the in 2 B The case shown requests an enlarged representation of the program suggestion display, for example by tapping the text output 25th , or if the method is carried out in such a way that the program suggestion display always covers the area of the entire container widget 21st is issued. In particular, an ad will be an entire widget 21st to 24 the display 20th filled out, referred to as a "Card". In the case shown, functionality symbols are also used 27 are output, the symbols for the vehicle functionalities 7th to 10 represent. In the exemplary embodiment, the functionality symbols 27 Greyed out at this point as long as they have not yet been activated by the mood program.

The in 2D In the case shown, the user has the confirmation button 26th operated and thereby activated the proposed relaxation program. The display is changed so that it is now a progress display 28 is displayed, in the exemplary embodiment with a numeric specified time value, which 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 another duration. Furthermore, the functionality symbols 27 still grayed out.

2E shows a case where the execution of the relaxation program has progressed. Ambient lighting is used as part of the relaxation program 8th of the vehicle 1 activated and set. This activation or setting is indicated by an enlarged functionality symbol in the representation 29a as well as a text output 29a ' down while the functionality symbols 27 be hidden.

The in 2F The case shown is the activation of the ambient lighting 8th complete and it will come back, similar to the one in 2D the case shown, the progress indicator 28 with the functionality symbols 27 displayed, with that of the ambient lighting 8th assigned functionality symbol 27 is no longer shown grayed out and instead highlighted. In 2F this is shown by a border, but any graphic highlighting can be used.

The in 2G The case shown, the execution of the relaxation program is also advanced and, analogous to that in 2E case shown, an audio output by means of the media playback device 7th is activated and set. The display now includes a corresponding functionality symbol 29b and a corresponding text output 29b ' .

Analogous to those in the 2E and 2G cases shown in the 2H The case shown is the massage device 9 or with the in 21st the case shown, the air conditioning device 10 activated and set. The display includes corresponding function symbols at the respective times of activation or setting 29c , 29d and text output 29c ' , 29d ' .

The in 2Y The case shown is finally the end of the total duration of the relaxation program, which is indicated by a termination symbol 30th is displayed with a completely filled progress bar. The display also includes the functionality symbols 27 , all of which are displayed as activated in the exemplary embodiment.

Following the execution of the relaxation program, the vehicle functionalities 7th to 10 can be deactivated again or the parameters set before the relaxation program can be set again.

With reference to the 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 3A and 3B cases was shown by the proximity detection unit 6th detects that a finger of the user is touching the touchscreen 4th approaching. This is interpreted as an operating intention and the display is changed so that buttons 31 , 32 are displayed, by means of which the user can make settings and influence the course of the relaxation program.

The in 3A The case shown was the ambient lighting 8th of the vehicle 1 activated and the display includes the corresponding functionality symbol 29a and the corresponding text output 29a ' . After the approach is detected, a button appears 31 to pause the currently running relaxation program. The user can click this button 31 inhibit the progress of the relaxation program, whereby its total duration does not expire any further. In particular, further buttons are then displayed which the user can press to continue or cancel the active mood program.

The in 3B The case shown is already the ambient lighting 8th and the media player 7th active, which is indicated by appropriately highlighted functionality symbols 27 is shown. In this case, the display also includes the progress display 28 . After the approach is detected, buttons will appear 31 , 32 displayed, which the user can use to pause the relaxation program or to mute the audio output that is playing in the background. In the embodiment shown here, pressing the corresponding button leads 32 to the fact that the media playback is muted according to the relaxation program and instead the previously set media playback is continued.

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

In reference to 4th an 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.

In a vehicle interior of the vehicle 1 is a display 41 arranged, which in the exemplary embodiment, the touch screen 4th includes. There are also vehicle seats in the interior 42 , 43 as well as ambient lighting facilities 44 . In particular, these are arranged behind decorative elements and for the indirect emission of colored light into the vehicle interior 40 suitable into it.

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 designed to help the driver of the vehicle 1 and / or to calm 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 a stress situation is 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 via biometric data.

In a proactive mode, in which the relaxation program is not actively called up by the user, but rather by the vehicle 1 is suggested, the data will be in the vehicle 1 existing sensors and functions are aggregated 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. A driving style can also be analyzed, for example on the basis of acceleration, braking and steering behavior or on the basis of keeping the vehicle in lane 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.

The relaxation program is a “choreographed”, time-orchestrated and coordinated activation and setting of the vehicle functionalities 7th to 10 gradually created 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 by means of which the user can record which vehicle functionalities 7th to 10 be 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 has the effect 32 ("Mute") to return to the previous sound source during the relaxation program.

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 above with reference to the 2 B and 2C shown. The ones in the widget 21st The representation shown can be shown enlarged, with a reduced icon overview showing which range of functions the program currently includes. The program can also be accessed directly using the confirmation button 26th to be started.

After confirmation by the user, the relaxation program begins and, in particular, it becomes a timer 28 showing the total duration and progress of the program.

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