COMBINING PRERECORDED AND LIVE PERFORMANCES IN A VEHICLE

FIELD

The disclosure relates generally to combining prerecorded audio performances with live audio performances.

BACKGROUND

Many people enjoy singing, and singing along with others. In karaoke, a prerecorded audio performance may be played, and a performance by a live singer may be added to the prerecorded performance, with microphones being used to capture and amplify the live performance.

Karaoke may be performed at a variety of venues. In some instances, karaoke may be performed at a commercial venue using specialized equipment. In other instances, karaoke may be performed in a home setting.

Some environments may be less conducive to performing karaoke enjoyably, however. The nature of vehicular environments, for example, may hinder or obstruct karaoke performances. Beyond casual use, the nature of vehicular environments may also hinder or obstruct the use of a vehicle for serious or professional recording purposes.

SUMMARY

Performing karaoke in vehicular environments presents issues and obstacles not present in typical karaoke environments. Microphones and other equipment that may be relatively easily passed from person to person in a studio or home environment may be more cumbersome to pass back and forth in a moving vehicle, in which passengers are often physically restrained. Noise within the vehicle may also wax and wane in ways difficult to anticipate and address, due to changes in the noise level of the environmental outside the vehicle as the vehicle moves, and also due to changes in noise made by the vehicle itself (e.g., as it travels at different speeds).

In some embodiments, the issues described above may be addressed by starting a prerecorded performance within a space or environment (e.g., a vehicle), then detecting a live audio performance at an area (e.g., a seating area) within the space. One or more properties of the prerecorded performance may then be modified based upon the live audio performance. For example, a volume of some portion or aspect of the prerecorded performance may be lowered (which may be referred to herein as “ducking”), and a combined audio performance based upon the modified prerecorded performance and the live audio performance may be provided. In this way, the cumbersome passing of equipment within the space may be obviated, while permitting manipulation of audio volumes of the combined performance that may enhance enjoyment.

For some embodiments, the issues described above may be addressed by playing a first audio performance through speakers within a vehicle and recording a second audio performance at a seating zone of the vehicle. At least one audio volume associated with the first audio performance may be ducked based upon a detection of the second audio performance, and the second audio performance may then be played in addition to the first audio performance. In this way, detection of a live performance may be used to initiate a karaoke performance without the use of hand-held equipment, and various audio volumes related to the first performance and the second performance may be subject to various adjustments to enhance the karaoke experience.

In some embodiments, the issues described above may be addressed by incorporating within a vehicle a set of microphones (e.g., beamforming microphones) directed to a plurality of seating areas within the vehicle, and a set of speakers. The speakers may be arranged in a surround-sound configuration around at least a periphery of the plurality of seating areas. A prerecorded first audio performance may be played through the set of speakers, and a live second audio performance may be detected at an identified seating area of the plurality of seating areas, through the set of microphones. The second audio performance may be recorded, and one or more volumes of the first audio performance may be lowered based upon the second audio performance. The recorded second audio performance may then be played in combination with the modified first audio performance. In this way, an audio performance within the vehicle may be detected, which may lead to adjustments of various audio volumes of the first performance, the second performance, or both, which may help overcome noise issues within the vehicular environment.

In various embodiments, the methods and systems disclosed herein may accordingly improve various vehicle-based performances. In some instances, the methods and systems may improve karaoke performances which may be more or less casual in nature.

In other instances, the methods and systems may also enable or improve the capacity of vehicles to serve as serious or professional recording environments (such as recording studios). For example, a recording artist may use the methods and systems to record vocal tracks and other original content while in a vehicle. The resulting tracks may be professional-quality recordings, similar to recordings mastered in a conventional recording studio.

It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.

DETAILED DESCRIPTION

Disclosed herein are methods and systems for combining prerecorded audio performances and live audio performances within a vehicle. FIGS. 1A-1C show seating areas for passengers within a vehicle, as well as door areas, dashboard areas, and rear deck areas. FIG. 2 shows an exemplary placement of microphones with respect to the seating areas, while FIG. 3 shows an exemplary placement of a set of speakers (e.g., in a surround-sound configuration) with respect to the seating areas. FIG. 4 depicts portions of a system for combining a prerecorded audio performance and a live audio performance in a vehicle, and FIG. 5 shows a flow chart of methods for combining such audio performances in a vehicle. FIGS. 6 and 7 depict portions of a vehicle cabin, and an in-vehicle computing system therein, for combining audio performances within the vehicle.

Turning to FIG. 1A, a vehicle 100 may have an interior 102 (e.g., a cabin) comprising a plurality of seating areas for accommodating passengers. In a front portion of interior 102, a first seating area 110 may accommodate a driver and a second seating area 120 may accommodate a passenger alongside the driver. A third seating area 130 and a fourth seating area 140 may accommodate further passengers in a rear portion of interior 102.

Seating areas 110, 120, 130, and 140 may be approximate portions of interior 102 in which passengers may be seated. Seating areas 110, 120, 130, and 140 may accordingly encompass portions of the three-dimensional volume of interior 102 in which the heads and mouths of passengers may be situated. Accordingly, when passengers seated in interior 102 sing or otherwise engage in a vocal performance, the resulting audio performance may be positioned to originate from one of seating areas 110, 120, 130, and 140.

Although interior 102 is depicted as having four seating areas, in various embodiments, interior 102 of the vehicle may accommodate more or fewer passengers, and in various positions or configurations. For example, for some vehicles, interior 102 may merely have two seats, while for other vehicles, interior 102 may have three or even four rows of seats.

The various seating areas of interior 102 may be positioned with respect to other areas of interior 102 that are relevant to the disclosed methods and systems. Turning to FIG. 1B, seating areas 110, 120, 130, and 140 are positioned proximate to, respectively, a first door area 112, a second door area 122, a third door area 132, and a fourth door area 142. First seating area 110 and second seating area 120 are also positioned near a dashboard area 152 in the front portion of interior 102, while third seating area 130 and fourth seating area 140 are positioned near a rear deck area 162 in the rear portion of interior 102.

During operation of vehicle 100, a first audio performance may be started. In various embodiments, the first audio performance may be a prerecorded audio performance (including, without limitation, a performance stored on compact disc or another digital storage medium). The first performance may be played in a variety of ways, such as by being played over a set of speakers in vehicle 100 by an infotainment system.

Following the initiation of the first audio performance, a second audio performance may be started. In various embodiments, the second audio performance may be a live vocal performance undertaken by a passenger of vehicle 100. Turning to FIG. 1C, for example, a front passenger 124 in second seating area 110 may begin singing. (Alternatively, a first rear passenger 134 in third seating area 130, a second rear passenger 144 in fourth seating area 140, or a driver 114 in first seating area 110 may begin singing.)

As discussed further herein, an audio performance by driver 114, passenger 124, passenger 134, and/or passenger 144 may be detected and identified as being performed at (and originating from) the corresponding seating area within vehicle 100, such as first seating area 110, second seating area 120, third seating area 140, or fourth seating area 150. In some instances, the identification of the seating area in which the audio performance is to occur may be indicated by a user (e.g., one of the occupants of vehicle 100), such as by selection. In other instances, the identification may be performed by vehicle 100 itself, along with detecting and capturing the second audio performance.

One or more properties of the first audio performance (such as volume levels associated with various aspects of the first audio performance) may be modified based on the detection of the second audio performance. For example, a volume level of the first audio performance may be lowered upon detection of the second audio performance. The second audio performance may then be played in addition to the modified first audio performance over a set of speakers of vehicle 100.

As a result, driver 114, passenger 124, passenger 134, and/or passenger 134 may participate in karaoke performances within vehicle 100 (as discussed further herein) without manually exchanging microphones, and in ways that substantially improve their enjoyment of the karaoke performance.

Turning to FIG. 2, a vehicle 200 (which may be substantially similar to vehicle 100) has a first seating area 210, a second seating area 220, a third seating area 230, and a fourth seating area 240. First seating area 210 and second seating area 220 are positioned in a front portion of an interior of vehicle 200, while third sitting are 230 and fourth sitting area 240 are positioned in a rear portion of an interior of vehicle 200.

Vehicle 200 has one or more sets of microphones positioned with respect to seating areas 210, 220, 230, and 240 to facilitate combining prerecorded audio performances and live audio performances. For example, the front portion of the interior of vehicle 200 may have a first set of microphones 216 positioned proximate to first seating area 210 and a second set of microphones 226 positioned proximate to second seating area 220. Similarly, the rear portion of an interior of vehicle 200 may have a third set of microphones 236 positioned proximate to third seating area 230, and a fourth set of microphones 246 positioned proximate to fourth seating are 240.

Each of the sets of microphones 216, 226, 236, and 246 may comprise one or more microphones, which may include beamforming microphone arrays (or other microphone arrays). Although depicted as corresponding with seating areas 210, 220, 230, and 240, in some embodiments, the microphones may correspond with other areas of vehicle 200 (such as door areas, dashboard areas, rear deck areas, or areas between and/or around the aforementioned areas). Moreover, in some embodiments, vehicle 200 may incorporate one or more omni-directional microphones and/or one or more directional microphones, either instead of or in addition to beamforming microphone arrays.

In some embodiments, beamforming microphone arrays of vehicle 200 may be broad-firing (e.g., with an orientation of the array perpendicular to a seat within a seating area). For some embodiments, beamforming microphone arrays of vehicle 200 may be end-firing (e.g., with an orientation of the array parallel to the seat within the seating area). End-firing beamforming microphone arrays may facilitate improved identification of areas from which sounds are originating.

Turning now to FIG. 3, a vehicle 300 (which may be substantially similar to vehicle 100) has a first door area 312, a second door area 322, a third door area 332, and a fourth door area 342. Vehicle 300 also has a dashboard area 352 and a rear deck area 362. Dashboard area 352, first door area 312, and second door area 322 are positioned in a front portion of an interior of vehicle 300, while third door area 332, fourth door area 342, and rear deck area 362 are positioned in a rear portion of an interior of vehicle 300.

Vehicle 300 also has a set of speakers positioned around a periphery of its seating areas (e.g., in a surround-sound configuration). For example, the front portion of the interior of vehicle 300 has one or more first door speakers 318 positioned in first door area 312, one or more second door speakers 328 positioned in second door area 322, and one or more dashboard speakers 358 positioned in dashboard area 352 Similarly, the rear portion of the interior of vehicle 300 may have one or more third door speakers 338 positioned in third door area 332, one or more fourth door speakers 348 positioned in fourth door are 342, and one or more rear deck speakers 366 positioned in rear deck area 362

In various embodiments, vehicle 300 may incorporate any number of speakers, and may also incorporate speakers at any positions within any of the various areas described above (e.g., door areas, dashboard areas, and/or rear-deck areas). For some embodiments, vehicle 300 may incorporate speakers within a periphery of the seating area (e.g., at various seating areas and/or between various seating areas).

Turning now to FIG. 4, a system 400 for combining two audio performances in a space (e.g., a vehicle) comprises a set of microphones 402, a set of speakers 408, and a processing portion 410. In turn, processing portion 410 may comprise a performance-detection portion 420, a first performance-modification portion 432, a second performance-modification portion 434, a recording portion 440, and a mixing portion 450.

As discussed herein, a first performance 412 may be initiated within the space (e.g., a prerecorded audio performance), such as by being played aloud. Following the initiated of first performance 412, a second audio performance 414 may be started within the space (e.g., a live vocal performance), such as by an occupant of the space singing along with first performance 412. Microphones 402 may capture sounds within the space and send them to processing portion 410. In the course of doing so, the sounds captured by microphones 402 may carry second audio performance 414.

Performance-detection portion 420 may process the sounds from microphones 402, such as by using echo-cancellers and/or noise-cancellers, in order to detect second performance 414. The echo-cancellers and noise-cancellers may reduce or eliminate various other sounds in the space, such as first performance 412 itself (or, for vehicular embodiments, road noises).

Moreover, the echo-cancellers and/or noise-cancellers may reduce or eliminate sounds from other occupants within the space. In some instances, the portion or area of the space in which the performing occupant is situated may be identified and associated with the performance before-hand, such as by being selected (e.g., manually, by verbal command, or by any other directed manner). For some instances, the portion or area of the space in which the performing occupant is situated may be initially established by performance-detection portion 420 (e.g., on-the-fly). Once the area of the space in which the performing occupant is situated has been identified, the echo-cancellers and/or noise-cancellers may reduce or eliminate sounds from originating from other areas of the space, in which other occupants may be situated (e.g., cross-talk within the space). In some embodiments, the echo-cancellers and/or noise-cancellers may be tuned to optimize vocal quality (which may come at the expense of greater isolation or separation of sounds from different areas within the space).

Once performance-detection portion 420 has detected second performance 420, first performance-modification portion 432 may modify one or more properties of first performance 412, such as by ducking one or more audio volumes of first performance 412. This ducking may provide a type of feedback to performers, which may improve and/or otherwise enhance the experience.

In some embodiments, content of first performance 412 within one or more frequencies ranges may be ducked. For example, content in a mid-band frequency range encompassing a majority of vocal frequencies may be ducked. For some embodiments, one or more audio channels of first performance 412 may be ducked before being presented to an up-mixer or surround-sound algorithm. For example, a center audio channel may be ducked before being up-mixed or presented to the surround-sound algorithm. In some embodiments, audio of first performance 412 being sent to one or more speakers within the space may be ducked, or one or more audio channels (e.g., a center channel) may be ducked, up to and including audio sent to all speakers in the space (e.g., encompassing all of first performance 412). For some embodiments, a source separation tool may be used to pre-process first performance 412 and identify different musical tracks therein, which may then be ducked. For example, a pre-processing tool may identify a vocal track within first performance 412, which may be ducked.

In various embodiments, audio volumes of first performance 412 falling under more than one category may be ducked. For example, in some embodiments, mid-band frequency ranges for a center audio channel (and/or correlated audio content) may be ducked before being up-mixed or presented to the surround-sound algorithm. Similarly, for various embodiments, multiple categories of audio volumes of first performance 412 may be ducked. For example, in some embodiments, mid-band frequency ranges may be ducked, and a center audio channel may also be ducked before being up-mixed or presented to the surround-sound algorithm.

In addition, once performance-detection portion 420 has detected second performance 420, second performance-modification portion 434 may modify one or more properties of second performance 414, such as by providing reverberation and/or compression (or another type of audio tuning). In some embodiments, reverberation and/or compression may be introduced to sounds captured by microphones 402 (e.g., locally at microphones 402, or downstream at processing portion 410). In various embodiments, reverberation and/or compression may be introduced before and/or after recording portion 440.

For various embodiments, modifications to second performance 414 may be targeted in different ways to different speakers within the set of speakers 408. For example, greater reverberation (and/or other tuning) may be given to speakers that are located proximate to an area in which the performer is situated. This may advantageously enhance the ability of the performer to hear their own voice, and may provide some reinforcement to their voice within the space.

Second performance-modification portion 434 may then present a modified version of second performance 414 to recording portion 440, which may record the performer's voice (e.g., while they are singing). As modified, second performance 414 may include, for example, reverberation and compression (as discussed herein).

Accordingly, first performance-modification portion 432 and recording portion 440 may present modified versions of first performance 412 and second performance 414 to mixing portion 450. In turn, mixing portion 450 may combine the two performances and send the combined performance to speakers 408. First performance 412 and second performance 414 may thereby be processed on separate paths, then mixed together to create a new performance, e.g., in which the voice of the performer in second performance 414 replaces the main vocals in first performance 412.

System 400 may thus advantageously enable a live performer to accompany a prerecorded performance while hearing the outcome of the combined performance as well, enabling real-time feedback. System 400 may also advantageously permit the creation of a recorded performance out of a performer's accompanying performance (e.g., second performance 414).

In some embodiments, recording portion 440 may optionally be absent. For some embodiments, a recording portion downstream of mixing portion 450 (which may be substantially similar to recording portion 440) may be present. Some embodiments may include both recording portion 440 as well as another recording portion downstream of mixing portion 450.

In some embodiments, the echo-cancellation and noise-cancellation used to detect second performance 414 may remove portions of the audio before passing it to second performance-modification portion 434. In some embodiments, all of first performance 412 may be removed, and recording portion 440 may then record solely the vocal performance of the performer, with none of the first audio performance.

Although discussed herein as being applicable in vehicles, other environments or spaces may be applicable. For example, a more conventional studio environment may employ designs such as those discussed herein.

In some embodiments, echo-cancellation and/or noise-cancellation may accommodate a tuning (e.g., a reverberation) introduced by second performance-modification portion 434. For example, an applied reverberation may be tuned to be low enough within the space (e.g., a vehicle) that a highly-directional microphone (e.g., of microphones 402) might not record an echoed performance.

For some embodiments, where echo-cancellation may result in a reduction of high frequencies, system 400 may recover high frequencies lost (e.g., in highly-compressed tracks).

In various vehicular embodiments, system 400 may interface with one or more other systems of a vehicle. For example, in some embodiments, system 400 may interface with a lighting system, which may alter colors of lighting when system 400 is recording, or when a user is getting close to a performance-degradation condition (e.g., “clipping”). Lighting modifications may be associated with particular seating areas (e.g., front seat areas or back seat areas).

For some vehicular embodiments, system 400 may interface with systems handling incoming phone calls. For example, incoming phone calls may be ignored, or may automatically interrupt the playing of first performance 412, second performance 414, or both. In some vehicular embodiments, system 400 may similarly be interrupted upon the detection of a condition bearing upon the safety of the vehicle and/or its occupants.

In some vehicular embodiments, system 400 may interface with systems detecting the raising or lowering of windows, convertible hoods, and other portions of the vehicle that may impact the audio performance, either by reducing or ending the performance process, or by increasing one or more volumes to overcome the impact.

In view of the above discussion, a first usage example, a second usage example, and a third usage example are described below, based upon vehicle 100 incorporating system 400 with its microphone arrays 402 (similar to FIG. 2), its set of speakers 408 (similar to FIG. 3), and its processing portion 410 (as in FIG. 4). In the first usage example, a driver and a first passenger occupy seating areas 110 and 120 in the front portion of interior 102, while a second passenger and third passenger occupy seating areas 130 and 140 in the rear portion of interior 102. The second passenger is performing karaoke, while the driver, the first passenger, and the third passenger are attending to the performance.

Seating area 120 is indicated to be the seating area from which the karaoke performance is to occur, such as by being selected manually via an in-vehicle computing system and/or infotainment system as disclosed herein. For example, the performance may be indicated as occurring from seating area 120 by a touch screen of the in-vehicle computing system and/or infotainment system. Meanwhile, a prerecorded audio performance may be queued up and initiated (e.g., via compact disc, a smart device coupled to the computing system and/or infotainment system, or another means).

Various beamforming microphone arrays of microphones 402 may be associated with seating areas 110, 120, 130, and 140. By capturing audio signals through the use of the beamforming microphone arrays, performance-detection portion 420 of processing portion 410 may detect the live audio performance when it occurs in seating area 120. As part of the detection, echo-cancellers and/or noise-cancellers may process the captured audio signals to reduce or eliminate various other sounds in the space, such as road noise, or any sounds that may be identified as originating outside seating area 120.

Following the detection of the live performance, first modification portion 432 may modify the prerecorded performance by ducking mid-band frequency ranges (to suppress prerecorded vocals) from speakers 408 positioned proximate to the active seating area (e.g., speakers adjacent to that seating in various areas of interior 102). Second modification portion 434 may introduce reverberation and/or compression to the captured live performance, and mixing portion 450 may thereafter mix the modified version of the prerecorded performance with the modified version of the live performance.

In the first usage example, system 400 may be configured to ignore incoming phone calls, and to end the combined performance if otherwise interrupted so that the occupants of vehicle 100 may focus on the performance. Similarly, the rolling-down of a window (or a convertible top) may be seen as a noise-generating event signaling the intended end of the combined performance, and system 400 may cease creation of the combined performance accordingly.

In the second usage example, a driver occupies seating area 110 in the front portion of interior 102, while a first passenger and second passenger occupy seating areas 130 and 140 in the rear portion of interior 102. The first and second passengers are performing karaoke alternatingly, while the driver is focusing on driving.

In contrast with the first usage example, in the second usage example, the identification of seating areas 130 and 140 as being seating areas from which the karaoke performance occurs is performed using portions of system 400 as disclosed herein (e.g., as part of a computing system and/or infotainment system of vehicle 100). So, for example, microphone arrays associated with seating areas 110, 120, 130, and 140 may identify live audio performances originating alternatingly from seating areas 130 and 140, and may alternatingly configure the modification of the prerecorded audio performances and/or the live audio performances in an accordingly alternating manner. In comparison with the first usage example, the passengers in the second usage example are pleased to sing along with whatever song happens to be playing on the radio.

In the second usage example, audio signals captured through the beamforming microphone arrays may be processed by performance-detection portion 420 to detect when live performances are occurring in any of seating areas 110, 120, 130, and/or 140. Echo-cancellers and/or noise-cancellers may be applied to separately reduce or eliminate various sounds outside of each seating area, and to separately evaluate whether and/or when a live performance is detected as occurring in any seating area.

Once detected, first modification portion 432 may then modify the prerecorded performance by ducking one or more speakers adjacent to the seating area from which the performance is detected at the moment (and/or to audio channels serving any such speakers).

In contrast with the first usage example, second modification portion 434 might not introduce any tuning to the captured live performance, and mixing portion 450 may thereafter mix the modified version of the prerecorded performance with the unmodified live performance.

In the second usage example, system 400 may be configured to accept incoming phone calls, which the occupants may deem more important than their karaoke experience. Moreover, the rolling-down of a window may be seen as an unintentional event (or at any rate as an event not intended to end the karaoke performance), and system 400 may operate in the noisier environment at a reduced level of functionality until more normal operation may be restored (e.g., until windows are rolled up once more).

In the third usage example, vehicle 100 carries a driver and one or more passengers whose seating areas are divided into a plurality of zones. For example, seating areas for the driver and/or one or more of the passengers may correspond with a first zone, while seating for one or more other passengers may correspond with a second zone. In various embodiments, the seating areas may correspond in any way with any number of zones, with each zone corresponding with one or more seating areas (up to and including one seating area per zone).

One of the zones may be indicated as a primary zone, while one or more other zones may be indicated as secondary zones. In the second audio performance, audio captured by microphone arrays 402 that is identified as originating from the primary zone may be segregated from audio captured by microphone arrays 402 that is identified as originating from a secondary zone. The primary zone may be handled as the zone from which a main performance is originating (e.g., from a main singer), while a secondary zone may be handled as a zone from which a supporting performance is originating (e.g., from one or more backup singers). In various embodiments, system 400 may accordingly capture multiple second performances.

Audio captured from the primary zone and audio captured from a secondary zone may then be tuned differently, e.g., by second modification portion 434 (such as by applying different reverberation, compression, gain, and/or equalization). For example, additional tuning could be applied to audio captured from the secondary zone (e.g., gain reduction, compression, and/or equalization) such that the audio captured from the secondary zone is appropriate for backup singers. The audio may also be recorded separately (e.g., by recording portion 440) and/or treated differently in the mixing process (e.g., by mixing portion 450).

In some embodiments, the various seating areas may be indicated as corresponding with the various zones by manual configuration (e.g., via an in-vehicle computing system and/or infotainment system as disclosed herein). Similarly, the various zones may be indicated as being primary or secondary by manual configuration. For some embodiments,

FIG. 5 shows a flow chart of a method 500 for combining two audio performances in a space (e.g., within a vehicle). At a first part 510, a first audio performance may be started through a set of speakers within a space. For example, a prerecorded audio performance may begin to be played. At a second part 520, live sounds may be captured through a set of microphones. In some embodiments, the microphones may be part of one or more beamforming microphone arrays.

At a third part 530, a second audio performance may be detected at an area within the space. For example, a live vocal performance may be detected at a seating area within a vehicle.

At a fourth part 540, various properties of the first performance may be modified based on the detection of the second performance. For example, one or more audio volumes of the first performance may be ducked. At a fifth part 550, various properties of the second performance may be modified. For example, a compression, a reverberation, and/or other types of tuning may modify the second performance.

At a sixth part 560, the second performance (as modified) may be recorded. Then, at a seventh part, a combined audio performance may be mixed together based upon the first performance (as modified) and the second performance (as modified). At an eighth part 580, the combined audio performance may be played.

FIG. 6 shows an example partial view of one type of environment for an audio customization system: an interior of a cabin 600 of a vehicle 602, in which a driver and/or one or more passengers may be seated. Vehicle 602 of FIG. 6 may be a motor vehicle including drive wheels (not shown) and an internal combustion engine 604 (such as vehicles 100, 200, and/or 300).

The External device interface 712 may additionally or alternatively provide a wireless communication interface to enable the in-vehicle computing system to synchronize data with one or more devices in the vehicle (e.g., the driver's mobile device) via WIFI direct, as described in more detail below.

One or more applications 744 may be operable on mobile device 628. As an example, a mobile device application 744 may be operated to aggregate user data regarding interactions of the user with the mobile device. For example, mobile device application 744 may aggregate data regarding music playlists listened to by the user on the mobile device, telephone call logs (including a frequency and duration of telephone calls accepted by the user), positional information including locations frequented by the user and an amount of time spent at each location, etc. The collected data may be transferred by application 744 to External device interface 712 over network 760. In addition, specific user data requests may be received at mobile device 628 from in-vehicle computing system or infotainment system 609 via the External device interface 712. The specific data requests may include requests for determining where the user is geographically located, an ambient noise level and/or music genre at the user's location, an ambient weather condition (temperature, humidity, etc.) at the user's location, etc. Mobile device application 744 may send control instructions to components (e.g., microphone, amplifier etc.) or other applications (e.g., navigational applications) of mobile device 628 to enable the requested data to be collected on the mobile device or requested adjustment made to the components. Mobile device application 744 may then relay the collected information back to in-vehicle computing system or infotainment system 609.

Likewise, one or more applications 748 may be operable on external services 746. As an example, external services applications 748 may be operated to aggregate and/or analyze data from multiple data sources. For example, external services applications 748 may aggregate data from one or more social media accounts of the user, data from the in-vehicle computing system (e.g., sensor data, log files, user input, etc.), data from an internet query (e.g., weather data, POI data), etc. The collected data may be transmitted to another device and/or analyzed by the application to determine a context of the driver, vehicle, and environment and perform an action based on the context (e.g., requesting/sending data to other devices).

Vehicle control system 730 may include controls for controlling aspects of various vehicle systems 731 involved in different in-vehicle functions. These may include, for example, controlling aspects of vehicle audio system 732 for providing audio entertainment to the vehicle occupants, aspects of climate control system 734 for meeting the cabin cooling or heating needs of the vehicle occupants, as well as aspects of telecommunication system 736 for enabling vehicle occupants to establish telecommunication linkage with others.

The control signals may also control audio output at one or more speakers 735 of the vehicle's audio system 732. For example, the control signals may adjust audio output characteristics such as volume, equalization, audio image (e.g., the configuration of the audio signals to produce audio output that appears to a user to originate from one or more defined locations), audio distribution among a plurality of speakers, etc. Likewise, the control signals may control vents, air conditioner, and/or heater of climate control system 734. For example, the control signals may increase delivery of cooled air to a specific section of the cabin.

Control elements positioned on an outside of a vehicle (e.g., controls for a security system) may also be connected to computing system or infotainment system 609, such as via communication module 722. The control elements of the vehicle control system may be physically and permanently positioned on and/or in the vehicle for receiving user input. In addition to receiving control instructions from in-vehicle computing system or infotainment system 609, vehicle control system 730 may also receive input from one or more external devices 650 operated by the user, such as from mobile device 628. This allows aspects of vehicle systems 731 and vehicle controls 761 to be controlled based on user input received from the external devices 650.
