[0022] Figure 1 A schematic diagram of a cockpit audio control system 100 according to one or more embodiments of the present application is shown. The cockpit audio control system 100 may include a first controller 110 (e.g., a VCU and a DCU), a first audio output device 120, a second audio output device 130, an in-vehicle playback source 140, a second controller 150 (e.g., one or more Bluetooth transceivers with Source and / or Sink modes), and an audio input device 160. Figure 1 Only one of each component is shown in the figure, but this is only for illustration. For each of the above components, the cabin audio control system 100 may include multiple such components (e.g., multiple in-vehicle playback sources 140). The in-vehicle playback source 140 may refer to a pre-installed and / or post-installed device with audio and / or video playback capabilities installed inside the cabin. In addition, Figure 1 The arrows of the connecting lines indicate the transmission direction of the audio data in the cockpit audio control system 100 .
[0023] exist Figure 1In the cockpit audio control system 100 shown, the first controller 110 can communicate with the second controller 150 and the in-vehicle playback source 140, and the second controller 150 can communicate with the first audio output device 120 and the second audio output device 130 (for example, to transmit data), so that the first controller 110 can be communicatively coupled with the first audio output device 120 and the second audio output device 130. The second controller 150 can also communicate with the audio input device 160 (for example, a smart phone, a mobile phone, a notebook computer, a tablet computer, a personal digital assistant (PDA), a game console, a music storage device, a wearable electronic device, etc.) and the in-vehicle playback source 140 and can send and receive audio data. For example, the second controller 150 can transmit audio data from the audio input device 160 to the in-vehicle playback source 140, and transmit audio content from the in-vehicle playback source 140 to the first audio output device 120 or the second audio output device 130.
[0024] In one or more embodiments, a plurality of in-vehicle playback sources 140 may be arranged in the cabin audio control system 100, wherein each of the in-vehicle playback sources 140 may include a user interaction device, such as a combination instrument on the main driving side (e.g., facing the main driving seat and including the center console) (e.g., an instrument display device facing the main driving seat) and an in-vehicle infotainment system (e.g., a vehicle computer system located on the center console), a human-computer interaction system on the co-pilot side (e.g., facing the co-pilot seat) (e.g., a display device facing the co-pilot seat), and a rear seat entertainment system located on the rear seat side (e.g., one or more rear seats) (e.g., a display device deployed above the rear seats and a display device located on the backrest of the main driving seat and / or the co-pilot seat).
[0025] In one or more embodiments, the first audio output device 120 may include a vehicle audio system, such as a plurality of vehicle speakers and / or corresponding audio amplifiers arranged in various locations in the cabin for collaboratively playing audio content. The second audio output device 130 may include a wired and / or wireless headset that can communicate with the second controller 150, such as a Bluetooth wireless headset, a headset, an in-ear headset, an earbud headset, etc.
[0026] In one or more embodiments, the audio content output by the first audio output device 120 and / or the second audio output device 130 may correspond to different in-vehicle playback sources 140. Specifically, the audio content played by the first audio output device 120 and / or the second audio output device 130 may be provided by any in-vehicle playback source 140, and the audio content provided by different in-vehicle playback sources 140 may be different from each other. For example, the in-vehicle infotainment system may provide the first audio content (e.g., symphony) for the in-vehicle audio system, the display device facing the co-pilot seat may provide the second audio content (e.g., rock music) for the in-vehicle audio system and / or the first earphone, and the rear seat entertainment system may provide the third audio content (e.g., country music) for the second earphone and / or the third earphone. In addition, the playback and pause of the above audio content on the corresponding in-vehicle playback source 140 may be controlled independently of each other. For example, when the third audio content is paused on the third earphone, the playback of other audio content on the corresponding in-vehicle playback source 140 may be maintained, so that the passengers may listen to the desired audio content independently of each other.
[0027] In one or more embodiments, the above correspondence between the audio output by the first audio output device 120 and / or the second audio output device 130 and the in-vehicle playback source 140 can be obtained by the first controller 110, for example, through communication with the second controller 150 and / or the in-vehicle playback source 140. In this communication, the first controller 110 can also obtain the use status of the in-vehicle playback source 140, the first audio output device 120 and / or the second audio output device 130 (including in use (unavailable), unused (available)), and obtain the corresponding user of these audio output devices (one of the in-vehicle playback sources 140). For example, the first controller 110 can receive feedback data from the rear seat entertainment system including information that the third earphone is being used by the rear seat entertainment system (for example, playing music), and can receive feedback data from the in-vehicle infotainment system that it is not performing any video and / or audio playback.
[0028] In one or more embodiments, different in-vehicle playback sources 140 may have priorities (hereinafter referred to as “playback priorities”) in the playback of audio content, so that the in-vehicle playback source 140 with a relatively high playback priority can be preferentially ensured to play the audio content on the in-vehicle playback source 140 with a relatively high playback priority compared to the in-vehicle playback source 140 with a relatively low playback priority. Specifically, when the in-vehicle playback source 140 with a relatively high playback priority plays its audio content on, for example, the first audio output device 120 and when the in-vehicle playback source 140 with a relatively low playback priority receives a user input about playing the desired audio content on the first audio output device 120, the first controller 110 instructs the in-vehicle playback source 140 with a relatively low playback priority to ignore the user input, so that the in-vehicle playback source 140 with a relatively high playback priority keeps playing its audio content.
[0029] In one or more embodiments, the above-mentioned playback priority can be determined according to the relative position of the vehicle-mounted playback source 140 in the cabin. For example, the vehicle-mounted playback source 140 that is relatively closer to the main driving side has a higher playback priority than other vehicle-mounted playback sources 140, and the vehicle-mounted playback source 140 that is relatively closer to the back seat has a lower playback priority than other vehicle-mounted playback sources 140. In this case, when other passengers (such as rear seat passengers) expect to switch the vehicle-mounted audio system to play their desired audio content, the vehicle-mounted playback source 140 that is closer to the main driving side (such as the vehicle-mounted infotainment system) can continue to play the audio content, thereby not causing the driver to pay attention to the switching of the audio content.
[0030] In one or more embodiments, different in-vehicle playback sources 140 may also have the same playback priority. Specifically, when a certain in-vehicle playback source 140 plays its audio content on, for example, the first audio output device 120 and when another in-vehicle playback source 140 receives a user input regarding playing the desired audio content on the first audio output device 120, the first controller 110 may instruct the in-vehicle playback source 140 to pause the playback and instruct the other in-vehicle playback source 140 to initiate playback of the corresponding audio content on the first audio output device 120.
[0031] In one or more embodiments, the first controller 110 may determine (e.g., formulate) a corresponding playback strategy for the playback of audio content on the first audio output device 120 and / or the second audio output device 130 according to the usage status of the vehicle playback source 140 and each audio output device and according to the playback priority between the vehicle playback sources 140. As described above, the playback strategy may refer to: when the playback priorities between the multiple vehicle playback sources 140 are different, when the vehicle playback source 140 with a relatively low playback priority receives a user input related to playing the desired audio content on the first audio output device 120 being used by another vehicle playback source 140 with a relatively high playback priority, the user input is ignored; when the playback priorities between the multiple vehicle playback sources 140 are the same, when the vehicle playback source 140 receives a user input related to playing the desired audio content on the first audio output device 120 being used by another vehicle playback source 140, the vehicle playback source 140 replaces the other vehicle playback source 140 to play on the first audio output device 120.
[0032] For example, when a certain in-vehicle playback source 140 plays its audio content on, for example, the second audio output device 130 and no other in-vehicle playback source 140 plays using the first audio output device 120 and when another in-vehicle playback source 140 receives user input regarding playing desired audio content on the first audio output device 120, the first controller 110 may detect a user input signal from the other in-vehicle playback source 140 (e.g., a user interaction device) and, based on user indication information represented by the user input signal, instruct the other in-vehicle playback source 140 to initiate playback of the corresponding audio content on the first audio output device 120. However, when the in-vehicle playback source 140 with a relatively high playback priority plays its audio content on, for example, the first audio output device 120 and when the in-vehicle playback source 140 with a relatively low playback priority receives a user input regarding the desired audio content to be played on the first audio output device 120, the first controller 110 may detect a user input signal from the in-vehicle playback source 140 with a relatively low playback priority (e.g., a user interaction device), and instruct the in-vehicle playback source 140 with a relatively low playback priority to ignore the user input based on the user instruction information indicated by the user input signal, so that the in-vehicle playback source 140 with a relatively high playback priority continues to play its audio content. Thus, in the case of selectively utilizing these audio output devices, the playback of the audio content on the in-vehicle playback source 140 with a relatively high playback priority may be preferentially ensured.
[0033] In one or more embodiments, the second controller 150 may transmit the audio content from the audio input device 160 to one of the multiple in-vehicle playback sources 140, or transmit the audio content from one of the multiple in-vehicle playback sources 140 to the first audio output device 120 or the second audio output device 130 according to the instruction associated with the playback strategy from the first controller 110. For example, the first controller 110 may instruct the second controller 150 to receive the stored audio data from, for example, the occupant's smart phone and transmit it to, for example, the in-vehicle infotainment system for storage, and may also instruct the second controller 150 to receive the stored audio data from, for example, the rear seat entertainment system and transmit it to, for example, the third headset for playback.
[0034] Figure 2 A method 200 for controlling the playback of audio content according to one or more embodiments of the present application is shown. The method 200 includes steps 210 and 220 and can be performed by an audio control system (e.g. Figure 1 The cockpit audio control system 100 is implemented as described above, wherein the audio control system may include a first audio output device, a second audio output device, a plurality of vehicle-mounted playback sources that provide audio content to the first audio output device and the second audio output device, respectively, and a first controller that is communicatively coupled to the first audio output device, the second audio output device, and the plurality of vehicle-mounted playback sources, respectively. In step 210, the first controller determines the corresponding usage status of the first audio output device, the second audio output device, and the plurality of vehicle-mounted playback sources. In step 220, based on the corresponding usage status and based on the playback priority between the plurality of vehicle-mounted playback sources, the first controller determines a playback strategy for the playback of the audio content on the first audio output device or the second audio output device.
