The object underlying the invention is to provide a method and a system for controlling an audio signal output for a vehicle, which contribute to a comfortable and safe operation of the vehicle and enable flexible audio signal output.

The object is solved by the independent claims. Advantageous embodiments are characterized in the subclaims.

The invention is characterized by a method and a corresponding system for controlling an audio signal output for a vehicle with at least one signal transmitter unit, a signal management unit and a signal output unit. There are provided a plurality of setting profiles each including a plurality of parameters for adapting the audio signal output. Depending on at least one predetermined condition, at least one of the setting profiles is activated. If multiple preference profiles are enabled at the same time, it will check for a conflict where two or more enabled preference profiles have a conflicting parameter and / or parameter with conflicting values, and if at least one conflict is detected, those affected by the conflict will be affected activated settings profiles adjusted according to at least one predetermined rule. The at least one signal generator unit respectively provides a transmitter signal which is representative of an audio signal to be output of the respective signal transmitter unit. The signal management unit determines in case of conflict depending on the respective encoder signal and the adjusted activated setting profiles, a control signal for controlling the audio signal output. The signal output unit generates the audio signal depending on the control signal.

In the event of a conflict, the signal management unit preferably determines the actuating signal as a function of the respective transmitter signal and the adapted activated setting profiles as well as the remaining, non-conflicting, activated setting profiles. If no conflict occurs, the actuating signal is determined depending on the respective encoder signal and the activated setting profiles. The adjusted enabled settings profiles and the enabled settings profiles that are not affected by a conflict are thus currently valid audio profiles. The signal management unit thus determines the control signal for controlling the audio signal output, depending on the respective transmitter signal and the currently valid audio profiles.

The settings profiles can be activated at different times. This means that, for example, a first setting profile is activated first. Subsequently, a second setting profile is activated and the first setting profile remains activated and thus active, since the at least one condition for the first setting profile is still fulfilled.

Advantageously, a holistically adapted audio signal output is thus made possible. The thus generated audio signal contributes, for example, to a small deflection of a driver. In this context, the signal management unit can be designed, in particular, as a central signal management unit, which manages the encoder signals on the input side and the control signal on the output side.

By checking for conflicts, multiple setting profiles can be activated at the same time, or remain enabled, allowing for flexible audio signal output. The signal management unit can find solutions for setting profile conflicts or parameter conflicts with the aid of a predetermined set of rules and thus provide conflict-free parameters or conflict-free values for the parameters for determining the actuating signal.

The setting profiles can in particular be preset setting profiles which comprise predefined parameters for adapting the audio signals. The parameters for adapting the audio signal output may include, for example, a pitch and / or frequency and / or volume of the respective audio signals to be output. Further, the parameters may include a selection of predetermined setting options, such as a voice of the navigation output or a musical genre. Thus, for example, for a given environmental situation, such as congestion, the adjustment profiles include parameters that influence the audio signal output to contribute to the comfortable and / or safe operation of the vehicle. For example, warning tones of a lane change assistant can be muted on an inner-city street so that an unnecessary distraction of the vehicle driver is avoided.

Preferably, the adjustment profiles relate to specific situations, for example driving in the rain, driving from the office to the home, driving to the office, night driving and so on. The settings profiles are activated in each case depending on the at least one condition, wherein several setting profiles can be activated at the same time, since several specific situations can prevail at the same time, for example when it is already dark on the way from the office to home and it is raining.

The respective setting profiles may include the same or different parameters. Further, the adjustment profiles may include an equal or a different number of parameters. It is advantageous if all adjustment profiles have the same parameters and the parameters have values adapted to a respective situation and thus at least partially different values.

The at least one setting profile can also be activated depending on an input of the vehicle user.

The at least one preference profile may also be activated depending on a provided specification value, the specification value being representative of vehicle-specific parameters for adapting the audio signal output. This enables a vehicle type-dependent adaptation of the audio signal output. The specification characteristic value includes, for example, information about the equipment of the vehicle, that is to say by way of example a number and position of the signal output unit of assigned loudspeakers.

Depending on the at least one setting profile, an evaluation can be made as to whether a respective transmitter signal leads to an audio signal output.

In particular, the signaling unit may include one or more audio sources such as music, telephony, navigation, active noise reduction, and so on.

The encoder signals can also be provided simultaneously or temporally overlapping. In particular, at least two signal generator units can each provide a transmitter signal for a temporally overlapping audio signal output.

The transmitter signal comprises, in particular, a time profile of the audio signal to be output and / or a calculation rule for generating the time profile of the audio signal to be output and / or a pointer to an entry in a database, comprising the time profile of the audio signal to be output. This allows efficient transmission of the signals. In particular, with regard to safety-related information, such as warning tones, it is becoming a particularly fast, reliable and robust transmission contributed.

At least one feature is associated with the respective transmitter signal, which is representative of a safety relevance of the transmitter signal and / or an urgency of the transmitter signal and / or a direction of the audio signal to be output and / or a position of the audio signal to be output and / or a type of the audio signal to be output and / or a number of channels of the audio signal to be output, wherein in the event that at least two signal generator units each provide a transmitter signal to a temporally overlapping audio signal output, at least one volume of audio signals to be output at the same time is adjusted as a function of the at least one feature when the actuating signal is determined. The type of audio signal to be output may include, for example, one of the category telephone call, movie, music or warning sound. In an advantageous manner, information can thus be output simultaneously depending on their relevance. Furthermore, by muting or delaying at least one audio signal to be output, it is possible to contribute the driver's attention to information in a targeted manner.

The control signal is for example representative of an audio signal to be output. In the context of determining the actuating signal, it is advantageously possible to prioritize the audio signal to be output. The prioritization takes place in this context, in particular depending on the encoder signal. The prioritization may additionally or alternatively be done depending on the setting profile. For example, in the case of several warning signals to be issued, only one most important warning signal can be output.

When determining the actuating signal as a function of the setting profile, an adaptation of the respective audio signal to be output is preferably carried out. The adaptation comprises in particular an adaptation of a volume of the audio signal to be output and / or an adaptation of a pitch of the audio signal to be output and / or an admission of the audio signal to be output with an effect and / or a loading of the audio signal to be output and / or a time delay of the audio signal output audio signal. For example, as part of the adaptation of the respective audio signal to be output, a voice of a navigation output can also be selected and the audio signal to be output can be determined to that effect. For example, as part of the adaptation of the respective audio signal to be output, a music direction can also be selected and the audio signal to be output can be determined to that effect. For this purpose, the setting profile, for example, first be provided to the respective signal generator unit. The audio signal output can be adjusted depending on the surrounding situation so that, for example, the volume is increased during a highway drive. Furthermore, the output can be adapted to predetermined settings of the driver, so that, for example, in a traffic jam a selection of music for the driver can be made.

In addition, the signal output unit may generate the audio signal depending on the adjusted and / or activated setting profiles. An adaptation of the audio signal output can be done decentralized. For example, a central processing unit can be dispensed with in this context. In this case, for example, only the adapted and / or activated setting profiles are provided to the signal output unit; an audio signal output then takes place independently of a setting signal. In this context, the signal output unit comprises a separately operated output system whose output is dependent on the at least one setting profile.

Preferably, the signal output unit is designed to output a haptic and / or optical signal. In addition to an acoustic output so haptic or optical signals can be output so that an attention of the driver of the vehicle can be targeted to a situation. Advantageously, the method allows centralized management of the signals, so that, for example, contradictory indications can be avoided.

The settings profiles may include parameters that may be temporarily overridden via an input of a vehicle user. The user can, for example, at any time change the automated selection, for example the volume, by the input.

In an advantageous embodiment, the adaptation of the activated setting profiles affected by the conflict case comprises an adaptation of the contradictory parameters or of the contradictory values of the parameters of the activated setting profiles affected by the conflict. This allows a simple solution of the conflict case with little effort. The adaptation of the contradictory parameters or of the contradictory values of the parameters of the activated adjustment profiles affected by the conflict occurs in particular as a function of the at least one predetermined rule.

In a further advantageous embodiment, determining the at least one adjustment profile depends on the at least one Condition checking whether a provided environmental characteristic that is representative of an environmental situation external to the vehicle meets a predetermined condition.

The at least one environmental characteristic preferably comprises information relating to an environment of the vehicle, that is, for example, parameters which act externally on the vehicle. This may, for example, be a current weather situation in which the vehicle is located. It may also be, for example, current traffic conditions, such as a traffic jam, in which the vehicle is located. Furthermore, the environmental characteristic may include location information such as position coordinates or information about a road type being traveled, such as inner-city road or highway. In this context, the environmental characteristic may further include, for example, a speed of the vehicle to determine, for example, depending on the speed of the traveled road type.

Alternatively or additionally, an operating characteristic value can be provided which is representative of an operating situation of the vehicle and the setting profile is activated as a function of the operating characteristic value. Alternatively or additionally, an interior characteristic value may be provided which is representative of an interior situation of the vehicle and the adjustment profile is activated as a function of the interior characteristic value.

This has the advantage that the activated setting profile for a particular situation in which the vehicle is located, is particularly suitable. The operating characteristic includes information concerning operation of the vehicle. This may include, for example, a current speed or an actual acceleration of the vehicle. Furthermore, this may include an operating state, that is, for example, an off state of the vehicle. The interior characteristic value may in particular include information relating to the vehicle occupant, such as, for example, a mood or attention of at least one vehicle user, in particular the vehicle driver.

In a further advantageous embodiment, the setting profiles are each assigned a priority and the at least one predefined rule comprises that, if at least one conflict is detected, between two or more activated setting profiles, activates the activated setting profile affected by the conflict, which has the highest priority and / or the other activated settings profiles affected by the conflict are deactivated. This allows a simple implementation.

In a further advantageous embodiment, the priority of the respective recruitment profile depends on the conditions that the recruitment profile fulfills during the activation. Preferably, the priority of the respective recruitment profile is the higher the more conditions it fulfills.

This has the advantage that the setting profile is used, which is particularly well suited for a particular situation in which the vehicle is located.

In a further advantageous embodiment, the respective parameters of the setting profiles are each assigned a priority and the at least one predetermined rule comprises, if at least one conflict is detected between two or more activated setting profiles, the parameter or parameter value affected by the conflict, which is the highest Priority, is used for determining the control signal to control the audio signal output. This allows the signal management unit to provide the conflict-free parameters needed for audio output.

In a further advantageous embodiment, a priority is assigned to the respective conditions and the at least one predetermined rule comprises, if at least one conflict is detected between two or more activated settings profiles, the setting profile affected by the conflict, which depends on the condition with the highest Priority has been activated, remains activated and the other or the other activated settings profiles affected by the conflict are deactivated. In particular, so environmental situations that are particularly critical, be given a higher priority and the setting profile can be used, which is particularly well suited for this critical situation in which the vehicle is located.

In a further advantageous embodiment, if a conflict is detected between two or more activated setting profiles, the parameters or parameter values affected by the conflict situation are adapted as a function of a detected selection input of the vehicle user. For this purpose, the vehicle user is preferably signaled possible parameter settings and the selection input of the vehicle user is recorded. The vehicle user can thus very easily influence the automated parameter settings, in particular in the event of a conflict.

In the method according to the invention, meta-profiles are provided, each containing data for resolving a conflict of a given combination of activated setting profiles, and the at least one predetermined rule comprises that in the case of conflict in which the respective predetermined combination of activated setting profiles is involved, the signal management unit determines the setting signal for controlling the audio signal output as a function of the metaprofile associated with this combination of activated setting profiles. Metaprofiles allow you to store conflict resolution without affecting the original preference profiles. The meta-profiles may include parameters that may be temporarily overridden via input from a vehicle user. The user can, for example, at any time change the automated selection, for example the volume, by the input.

In one embodiment, if an input of a vehicle user relating to the audio signal output is made during an audio signal output in which the control signal is determined depending on one of the metaprofile, that input of the vehicle user is detected and the data of that one metaprofile becomes dependent on the input adapted to a vehicle user. The customized meta-profile is preferably saved and replaces the original meta-profile. By directly influencing set values, the vehicle user is given the option of temporarily overriding and / or permanently storing the value for adapting the audio signal output.

In a further advantageous embodiment, the vehicle user is signaled in each case an automatic conflict resolution and a response input of the user for the audio output made in response to the signalized conflict resolution is detected. Depending on a variety of rating inputs, a preferred parameter setting of the vehicle user is determined and, depending on the preferred parameter setting, all or a portion of the meta-profiles are adjusted. With the help of such a hiring history and an intelligent data processing, the user behavior can be learned and the meta-profiles can be adapted to the needs of the vehicle user.

The method described above for controlling the audio system can also be applied to other systems that do not relate to audio management. The method can be used on all systems with profiles containing lists of common parameters.

The invention is characterized according to a further aspect by an apparatus according to claim 10 for controlling an audio signal output for a vehicle. Advantageous embodiments of the method for controlling an audio signal output for a vehicle are also valid for the device according to the further aspect.

Nowadays, a plurality of predetermined acoustic warning signals such as safety warnings for critical situations, for example oil level or a so-called "blind spot warning" as well as information about a vehicle condition, for example a wiping water condition, can be output in a vehicle. Furthermore, today exists in the vehicle, for example, a noise insulation, a motor-sound generator, a music output, voice output such as navigation, telephony or operating sounds for example, control screens (so-called "touch screens"). Depending on the situation, such as the environment, such as weather and traffic conditions, driving behavior, such as speed and type of ride, and preferences, mood or attentiveness of a driver of the vehicle, a holistically adapted audio / acoustic environment is to be created in the vehicle.

1 shows an exemplary block diagram for an audio system 1 for a vehicle.

The audio system 1 comprises at least one signaling unit 5 , a signal management unit 3 and a signal output unit 15 . 17 . 19 ,

The signal management unit 3 includes, for example, an audio profile delivery unit 7 and a central audio management unit 9 , Furthermore, the signal management unit comprises 3 for example, an audio profile specification 11 and an audio management model 13 ,

To create a fully customizable audio / acoustics environment, one or more adjustment profiles P are introduced in the vehicle. In particular, one or more audio / acoustic adjustment profiles P are introduced for one or more aspects or combinations of aspects of the audio output, in particular with regard to warning sounds and music.

The management of a set of setting profiles P is performed by the audio profile providing unit 7 adopted, which selects the settings profile P based on a current driving situation. Depending on a setting profile selection PW by the driver and / or an automatic assistance system, such as the driver condition detection or the environmental situation, at least one setting profile P from the setting profile selection PW of the existing setting profiles P is activated at a given time. The setting profiles P are adjusted when a conflict occurs between two or more activated preference profiles aP. The audio profile deployment unit 7 is formed, the audio management unit 9 to provide valid audio profiles vP (cf. 2 ).

The central audio management unit 9 manages all incoming encoder signals G1, G2, G3, G4, that of the at least one signal generator unit 5 to be provided. The central audio management unit 9 generates with reference to the settings profile selection PW an integral, the current driving situation corresponding output signal A. The central audio management unit 9 has the advantage that not every single audio system has to manage the valid audio profiles vP and decentralized, a holistic audio adaptation must be achieved.

For example, events and information of the vehicle are used as first transmitter signals G1, which are transmitted by security systems such as a parking pilot, a lane change assistant or a distance control system, for example.

In addition, the existing audio sources which are available in the vehicle and which, for example, provide second transmitter signals G2 are preferably managed. These are, for example, music, telephony, navigation, noise reduction or the like.

The central audio management unit 9 has, for example, access to a sound database which contains predefined sounds for certain situations and makes them available as third encoder signals G3. The tones are selected in the context of the currently valid audio profiles vP, with the sounds from the central audio management unit 9 adaptively to the current environment information. This happens, for example, by changing the pitch, frequency, volume, effects or filters.

The central audio management unit 9 For example, it also manages tone generators that provide fourth encoder signals G4. These may be, for example, noise reduction systems (so-called "noise cancellations") or systems that are commanded by the central audio management unit 9 produce certain sounds synthetically. Notwithstanding the in 1 illustrated signaling unit 5 The first, second, third and fourth encoder signals G1, G2, G3, G4 can also be provided by a plurality of separate signal generator units.

The totality of all of the settings profiles P managed settings and options is z. In the holistic audio profile specification 11 which includes, for example, information about signal sources and / or audio sources. The holistic audio profile specification 11 is available to all components affected by the settings profiles P, such as decentralized audio sources or decentralized sound generators 19 or the central audio management unit 9 available in the system. The holistic audio profile specification 11 allows, for example, the communication between the audio profile providing unit 7 and the central audio management unit 9 or other components such as distributed audio sources / sound generators 19 in the vehicle. The audio profile specification 11 is for example in the form of a database in a memory device of the signal management unit 3 saved.

From the encoder signals G1, G2, G3, G4 a holistic audio signal A is generated, which has been adapted to the current driving situation and in the context of the currently valid audio profiles vP. For the creation of this integrated audio signal A has the central audio management unit 9 Access to the holistic audio management model 13 , which contains a set of rules, on the basis of which features of the individual first, second, third and fourth encoder signals G1, G2, G3, G4, such as their urgency, safety relevance, or criticality, can be evaluated. Based on this evaluation, for example, the first, second, third and fourth encoder signals G1, G2, G3, G4 from the central audio management unit 9 processed. This is the holistic audio signal A depending on a generation of missing sounds, for example by means of the tone generator determined. Furthermore, the integrated audio signal A is determined as a function of a processing and adaptation of existing tones from the sound database and by means of a prioritization of the various audio signals with subsequent mixing.

In the case of mixing, audio signals to be output can be correlated, highlighted or even eliminated, in particular based on the evaluation.

In this case, for example, in the event that the audio signals to be output overlap in time, a comparison of the respective overlapping audio signals is performed on the basis of the features, wherein in case the overlapping audio signals represent an identical or similar information output, an output time of the respective audio signals is unified with each other. This can be added to the other audio signal by means of superimposing, mixing or by analyzing characteristic characteristics of the audio signal, for example pitches or recurrent patterns. Such an adjustment can also be referred to as correlation. Finally, the output of the integrated audio signal.

The integrated audio signal A, which was generated in the context of the currently valid audio profiles vP, is finally transmitted via the audio output system 15 of the vehicle. Additional signals can be sent to other audiorelevant actuators 17 be transferred, for example, active engine mounts and noise generators, haptic elements or optical signal displays or external speakers. The audio output system 15 , the audio-relevant actors 17 as well as the decentralized audio sources / tone generators 19 can also be used as a signal output unit 15 . 17 . 19 be designated.

In one embodiment, in the vehicle partially decentralized audio generator 19 which are not present at the central audio management unit 9 are connected or partially not at all with the audio profile providing unit 7 are connected.

In a further embodiment, the valid audio profiles vP from the audio profile providing unit 7 are also made available to all individual systems (security systems, multimedia systems) and these adapt their audio output to the currently valid audio profiles vP. In this case, the central audio management unit 9 be omitted, the output of a holistic audio signal A is then not possible.

In a further embodiment, the integrated output signal A contains direction-dependent and location-dependent audio information, which selectively drive individual loudspeakers in a multi-channel loudspeaker system and thus enable the output of a directional audio signal.

In a further embodiment variant, the dynamic selection of the adjustment profiles P depends on models. This can be, for example, a driver model or a driver environment model, which contains information on the current state of the driver or on the current environment, such as highway or traffic jam. If the driver is in an inappropriate state, for example in the event that he is too tired, or for the situation a disadvantageous range of the viewing direction has been determined, this leads to a Einstellprofilauswahl PW a Einstellprofils P, which positively this state in favor of the current driving situation affected. For example, in this case, the music selection is made to make the driver more alert, or to output a directional audio signal that directs the driver's attention to a certain direction.

In a further embodiment variant, the setting profile selection PW of the setting profiles P can have an influence on other profile-based systems in the vehicle which, for example, manage visual, optical haptic elements.

2 shows an exemplary block diagram for the audio profile providing unit 7 ,

The audio profile deployment unit 7 has a profile database 73 , an audio profile activation unit 75 , an audio profile management unit 76 , a conflict management unit 77 , Profile adjustment unit 78 and a metaprofile database 79 on. Alternatively or additionally, the audio profile providing unit 7 have a policy database.

To create a fully customizable audio / acoustics environment, one or more adjustment profiles P are introduced in the vehicle. The settings profiles are, for example, in the profile database 73 the audio profile deployment unit 7 saved. The management of a set of setting profiles P is performed by the audio profile providing unit 7 adopted, which selects the settings profile P based on a current driving situation. This is indicated by the audio profile deployment unit 7 for example, the audio profile activation unit 75 on. The audio profile activation unit 75 receives, for example, profile selection information PWI that corresponds to the specific wishes of the driver. The profile selection information PWI corresponds, for example, to a static choice. For this purpose, for example, an input E of the driver is detected, for example by means of an input unit 21 ,

The audio profile activation unit 75 also receives profile dialing events PWE, for example from sensors and security systems 23 of the vehicle and lead to an automatic choice of setting profiles P. The automatic selection of the adjustment profiles P corresponds for example to a dynamic choice. From the totality of the setting profiles P, a current setting profile selection PW from the audio profile providing unit thus becomes 7 determined.

The audio profile activation unit 75 is in particular designed to select and activate at least one of the setting profiles P depending on predetermined conditions. This is the audio profile activation unit 75 formed, for example, depending on at least one provided environmental characteristic K, which is representative of an environmental situation external to the vehicle, the at least one setting profiles P to determine and activate. Here, the audio profile activation unit 75 in particular be designed to check whether the at least one environmental characteristic value K in each case exceeds or falls below a predetermined threshold value.

An audio profile management unit 76 the audio profile deployment unit 7 forwards the activated settings profiles aP to the conflict management unit 77 further. The conflict management unit 77 the current profile selection PW is provided by the audio profile management unit.

The conflict management unit 77 serves to resolve conflicts between parameters of the simultaneously active settings profiles aP. A conflict arises in particular when a same parameter with different values is defined in different active setting profiles aP. For example, two active setting profiles may have different values for a volume of a radio.

The conflict management unit 77 is configured, when several setting profiles aP are simultaneously activated, to check whether a conflict occurs in which the activated setting profiles aP have contradictory parameters and / or identical parameters with conflicting values, and if at least one conflict is detected, the activated setting profiles aP, which have the contradictory parameters or parameter values to adapt according to at least one predetermined rule. Preferably, the conflict manager is the audio profile manager 76 provide all the non-conflicting parameters and / or non-conflicting meta-profiles M needed to output the audio, replacing the conflicting activated adjustment profiles aP.

Since the setting profiles P and thus also the activated setting profiles aP can have different parameters that are not in conflict with each other, conflicting cases need not necessarily occur if several setting profiles P are activated. For example, a first preference profile may include a first parameter that defines a particular radio station, and a second preference profile may include a second parameter that defines a volume of the radio.

In the event that the conflict management unit 77 does not detect a conflict between the activated setting profiles aP, a set of the parameters of all the activated setting profiles aP from the audio profile providing unit 7 to the audio management unit 9 forwarded. In this case, no conflict resolution is required and a clear set of parameters can easily be found for the audio management unit 9 ,

When conflicts occur, the conflict management unit takes action 77 in particular, to a set of rules that has predetermined rules for resolving potential conflicts. For example, the rules and regulations can be stored in a set of rules databases and can be used to solve the respective conflicts. For this purpose, the setting profiles P can be examined in advance for possible conflicts and a rule can be assigned to the possible conflicts.

In one embodiment, the settings profiles may each have a priority associated with them, and if at least one conflict between two or more activated settings profiles aP is detected, then the activated highest-priority activated settings profile aP affected by the conflict remains activated and the other affected by the conflict activated settings profiles aP are deactivated.

Alternatively, the respective parameters of the setting profiles P can each be assigned a priority and, if at least one conflict between two or more activated setting profiles aP is detected, the parameter or parameter value having the highest priority affected by the conflict case becomes the one for the conflict affected activated recruitment profiles aP.

Alternatively or in addition to the rules database, the audio profile providing unit 7 the metaprofile database 79 in which metaprofiles M are deposited. The meta-profiles M each comprise data for solving a specific conflict of a given combination of activated ones Recruitment profiles aP. In the case of conflict in which the respective combination of activated setting profiles aP is involved, the audio management unit determines 9 for example, depending on the metaprofile M associated with this combination of activated setting profiles aP, the actuating signal S for controlling the audio signal output.

For example, the data of the metafiles M may include values and / or functions for processing the original values from the combined enabled settings profiles aP. Alternatively or additionally, the data may include or define an external influencing variable, based on which it is decided which activated setting profile aP and / or which parameter or parameter value is used. For example, a current time can be used for solution finding. For example, in the morning, the value for a first parameter may be used by a first preference profile, and in the afternoon the value of the first parameter may be used by a second preference profile.

The respective meta-profile M is preferably used for each recombination of precisely these activated setting profiles aP with this occurring specific conflict. The meta profile M comprises, for example, a substitute parameter and / or substitute parameter value for the specific conflict-causing parameter of the activated setting profiles aP involved in the specific conflict and / or a rule for determining this substitute parameter or substitute parameter value.

Preferably, the data of the respective meta-profiles M can be adapted depending on the input of the user (cf. 3 to 5 ).

The audio system 1 ( 1 ) includes, for example, a control unit 25 on which a first program for controlling the audio signal output is stored, which is described below with reference to the flow chart of the 3 is explained in more detail.

In a step S1, the program is started in which, for example, variables are initialized.

In a step S3, at least one of the adjustment profiles P is activated, depending on the at least one predetermined condition. In addition, the setting profiles P may be activated depending on an input E of the vehicle user of the vehicle. The adjustment profile P is activated, for example, as a function of a detected environmental characteristic value K and / or of a detected operating characteristic value and / or a detected interior characteristic value. The determination of the at least one adjustment profile as a function of the at least one condition comprises, for example, checking whether the provided environmental characteristic value K and / or operating characteristic value and / or interior characteristic value satisfies a predetermined condition. The environmental characteristic value K and / or the operating characteristic value and / or the interior characteristic value, for example, reflect a driving situation in which the vehicle is located. The activated setting profiles aP can also be referred to as setting profile selection PW.

If several setting profiles aP have been activated or are active, it is checked in a step S4 whether a conflict occurs in which the activated setting profiles aP have contradictory parameters and / or identical parameters with conflicting values, and if at least one conflict is detected the activated adjustment profiles aP, which have the contradictory parameters or parameter values, adjusted according to at least one predetermined rule.

The adjusted activated setting profiles aP and the activated setting profiles aP not affected by a conflict are used for an adaptation F of the encoder signals G1, G2, G3, G4. The adjusted activated settings profiles aP and the activated setting profiles aP that are not affected by a conflict are thus currently valid audio profiles vP.

In a step S5, the adaptation F is made, depending on currently valid audio profiles vP and the encoder signals G1, G2, G3, G4. The adaptation F may relate in particular to a change in a volume, a prioritization or a music selection.

In step S7, therefore, a control signal S is generated, depending on the currently valid audio profiles vP and the encoder signals G1, G2, G3, G4. Depending on the control signal S, for example, an output of the integrated audio signal A takes place. For example, an optical or haptic output of the audio-relevant actuator can also be used 17 respectively.

The program will then be run again, for example. The setting profiles P and / or meta profiles M can include parameters that can be temporarily overridden via a further input IN of the vehicle user. For example, the user can change the automated selection, for example the volume, at any time by further input IN. Temporary here means in particular for an activation phase if the change is not saved. In an optional step S8, therefore, the further input Detected IN of the vehicle user and the audio output signal A depending on the further input IN adjusted.

The program is terminated in a step S11, for example, when the use of the vehicle is terminated.

The setting profiles P can be activated at different times. For example, a first setting profile is activated at a first time in step S3. For example, the first preference profile has a first volume parameter representative of a volume change. For example, the first parameter is 50%. The value 50% means that the volume of the encoder signal G1, G2, G3, G4 is halved. Since no further setting profile is activated, in step S7 the audio output takes place according to the first setting profile.

After a certain time, a second adjustment profile is activated during a renewed passage of the first program in step S3 and the first adjustment profile remains activated since the at least one condition for the activation of the first adjustment profile is still fulfilled. For example, the second preference profile also has the first volume parameter, which is representative of the volume change. For example, the first parameter has the value 100% in the second setting profile.

Since two setting profiles are now activated, it is checked in step S4 whether the first setting profile and the second setting profile have parameters with conflicting values. This is the case here, so that in each case the values of the first parameter are adapted according to at least one predetermined rule. For example, a first meta-profile M is read in which has data and / or at least one rule for resolving the conflict between the first and second setting profile.

The signal management unit 3 determined in step S5 depending on the first metaprofile M, the control signal S to control the audio signal output. For example, the first metaprofile M may include the rule that the mean value is formed with respect to the values of the first parameter. Alternatively, the metaprofile M may for example comprise a predetermined value for the first parameter.

In step S7, the integrated audio signal A is output with the volume predetermined by the metaprofile M.

Preferably, for example, the vehicle user, because he does not like the volume, by a predetermined operation of an input device 34 For example, in the vehicle arranged volume control, change the volume of the output signal.

4 shows an exemplary flowchart for a second program for controlling an audio signal output. The steps S1 to S7 of the first program correspond to the steps S21 to S27 of the second program. The second program differs from the first program in that in a step S28, when an input relating to the audio signal output is made during an audio signal output in which the control signal S is determined depending on one of the metaprofiles M, this input of a vehicle user is detected and in a step S29, the data of the one metaprofile M and / or the metaprofile associated settings profiles P are adjusted and stored depending on the input of the vehicle user. Further, in the step, the audio output signal A is adjusted depending on the further input IN.

The input of the user is, for example, from the audio management unit 9 and to the audio profile adjustment unit 78 forwarded.

The changes in the automated selection can be stored, for example, directly in the respective settings profile P and / or the respective meta profile M, which is affected by the changed setting by the set value of the input is stored directly. Alternatively or additionally, it is possible for the respectively set values to be detected over a predetermined period of time and for the change in the automated selection to be determined as a function of the setting values acquired over the predetermined time. For this purpose, for example, a frequency table can be determined and the most frequently set value is used for the automated parameter setting, that is to say for the corresponding meta profile M and / or the setting profiles associated with the corresponding meta profile M. Has, for example, the conflict management unit 77 5 times a radio station A for the automated setting supplied, but the user of which has changed to a radio station B 3 times, then the set of rules and / or metaprofile M is adjusted so that the conflict management unit 77 in the following conflict, the radio station B supplies. For the detection of the set values of the override, the storage of the values in the associated adjustment profiles P and / or meta-profiles M and a data processing of a history for the generation of the value to be stored is, for example, a profile adaptation unit 78 (please refer 2 ).

5 shows an exemplary flowchart for a third program for controlling an audio signal output. The third program is different from the first program in that an automatic conflict resolution is signaled to the vehicle user in a step S38 and a judgment input of the user for audio output made in a step S39 in response to the signalized conflict resolution is detected, and in a step S40 depending on a plurality of evaluation inputs, a preferred parameter setting of the vehicle user is determined and, depending on the preferred parameter setting, all or part of the meta-profiles M are adapted.

In particular, the vehicle user may provide parameter-unspecific feedback by the vehicle user making a one-dimensional or multi-dimensional assessment of the attitude in response to the signalized conflict resolution, for example, by pressing a "Like me / dislike button." ). After establishing a history, intelligent data processing can be used to identify and calculate patterns to which parameter settings the feedback relates. This has the advantage that a provision of control interfaces for all influenceable by the vehicle user parameters can be omitted or only a few control interfaces are required.
