[0034] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.
[0035] like Figure 1As shown, it is a schematic diagram of the application scenario of the embodiment of the present application. The in-vehicle entertainment system in the application scenario diagram includes multiple user interaction subsystems, wherein the user interaction subsystem can be understood as an operating platform for realizing human-computer interaction based on a display screen. Each user interaction subsystem corresponds to a player and a display screen, where the player here refers to the audio output port of the vehicle itself, such as a car speaker or speaker, and the display screen here refers to the vehicle display screen, such as a central control screen or an auxiliary screen in the back row. In this application scenario, the in-vehicle audio control method based on the embodiment of the present application supports multiple users to dynamically connect their own audio output devices to the in-vehicle entertainment system. The user's own audio output device can be, for example, a Bluetooth headset, a player on AR glasses, etc., which is different from the player shown in the figure. Each user interaction subsystem creates an audio output thread based on the connected audio output device, that is, determines the respective audio output strategy according to the audio playback channel corresponding to the created audio output thread, so as to realize that users using each user interaction subsystem can independently enjoy their own audio playback.
[0036] See attached Figure 2 , Figure 2 A method for controlling in-vehicle audio output is provided according to an embodiment of the present application. The method is used in an in-vehicle entertainment system. The in-vehicle entertainment system includes multiple user interaction subsystems. The multiple user interaction subsystems are specifically multiple operating platforms for realizing human-computer interaction based on the in-vehicle screen. The in-vehicle screen in the in-vehicle entertainment system in the embodiment of the present application can be a display screen in the cockpit or in-vehicle AR glasses. Generally, the multiple user interaction subsystems in the in-vehicle entertainment system refer to subsystems for human-computer interaction based on the left or right display screens in the rear row of the cockpit, or subsystems for human-computer interaction based on in-vehicle AR glasses.
[0037] like Figure 2 As shown, the implementation process of the vehicle audio output control method of the present application mainly includes the following steps S10 and S20.
[0038] Step S10: acquiring device information of a bound audio output device corresponding to the user interaction subsystem, creating a first audio output thread corresponding to the audio output device based on the device information, and binding the first audio output thread to the user interaction subsystem;
[0039] Specifically, in this embodiment, the user interaction subsystem is mainly used to provide audio and video playback services to users through interaction with users; multiple user interaction subsystems in the in-vehicle entertainment system are independent of each other. In actual applications, in order to facilitate the management of the audio channels used by each user interaction subsystem for audio and video playback, each user interaction subsystem is bound to its own independent audio output thread. The first audio output thread in this embodiment can be understood as the audio output channel corresponding to the external audio output device.
[0040] In this embodiment, the audio output device is specifically a Bluetooth headset device or a USB interface headset device. Further, when the audio output device is specifically a Bluetooth headset device, the device information obtained includes at least the device type and the Bluetooth MAC address; when the audio output device is specifically a USB interface headset device, the device information obtained includes at least the device type, the USB interface headset sound card number and the pulse code modulation device (PCM) number.
[0041] It should be understood that before executing step S10, the system also includes a step of real-time monitoring of audio device connection events. Specifically, when the in-vehicle entertainment system detects an audio device connection event, the audio output device is selected for binding according to the user operation; and the corresponding relationship between the bound audio output device and the user interaction subsystem is determined according to the audio device connection event or the user operation. The user operation may specifically include the operation performed by searching and binding the user's personal audio device. Further, when the audio output device is a Bluetooth headset device, the corresponding relationship between the audio output device and the user interaction subsystem is determined based on the user operation (for example, the user's selection operation on the in-vehicle screen corresponding to the user interaction subsystem); when the audio output device is specifically a USB interface headset device, the corresponding relationship between the audio output device and the user interaction subsystem is determined based on the USB interface insertion event. When the in-vehicle AR glasses are bound to the system, they are identified as USB sound card headsets in the audio as an audio output device. Therefore, when the system detects a USB interface insertion event, combined with the device information, it can be identified that the bound audio output device is AR glasses.
[0042] Step S20: determining a first audio output thread corresponding to the user interaction subsystem according to the audio playback request input by the user acquired by the user interaction subsystem, and using an audio output device corresponding to the first audio output thread to perform audio playback.
[0043] Specifically in this embodiment, the vehicle-mounted screen corresponding to the user interaction subsystem can provide audio and video services or APPs for users to choose to use. In a multi-user usage scenario, the system can determine the corresponding audio output device based on the first audio output thread currently bound to the user interaction subsystem.
[0044] Furthermore, the vehicle audio output control method implemented based on the above steps S10 and S20 also includes: when the vehicle entertainment system is started, a second audio output thread corresponding to the vehicle's own audio output port is created; the second audio output thread in this embodiment can be understood as an audio output channel corresponding to the vehicle's own audio output port.
[0045] Correspondingly, during the process of audio playback by the audio output device corresponding to the first audio output thread, when the user interaction subsystem obtains the audio output switching request input by the user, the thread currently bound to the user interaction subsystem is changed from the first audio output thread to the second audio output thread, and the audio is played using the vehicle's own audio output port corresponding to the second audio output thread. It should be understood that the vehicle screen corresponding to the user interaction subsystem can provide an audio output switching button that can be selected by the user to facilitate the user to flexibly switch the sound output mode of the audio and video playback service being used. Furthermore, the user can also switch the audio output by disconnecting the currently connected audio output device and connecting other new audio output devices. In this way, the system creates a corresponding audio output thread based on the newly bound audio output device to achieve audio output switching. The method is the same as the process of creating the first audio output thread and using the audio output device corresponding to the first audio output thread for audio playback described above, which will not be repeated here.
[0046] See attached Figure 3 ,exist Figure 2 Based on the embodiment shown, Figure 3 This is a schematic diagram of a specific implementation method of a vehicle audio output control method provided according to an embodiment of the present application. As shown in the figure, after the vehicle entertainment system is started, the following steps S100 to S400 are specifically performed.
[0047] Step S100: creating a second audio output thread corresponding to the vehicle's own audio output port, and binding the audio output strategies of each user interaction subsystem to the second audio output thread;
[0048] Specifically in this embodiment, each user interaction subsystem may correspond to its own audio output strategy. Generally, by default, after the system is started, the second audio output thread corresponding to the vehicle's own audio output port will be created and bound to each user interaction subsystem, which is equivalent to setting the default audio output of each interaction subsystem to the vehicle speaker or speaker output.
[0049] Step S200: After an audio output device connection event is detected, an audio output device is selected for binding according to a user operation, and a corresponding relationship between the bound audio output device and the user interaction subsystem is determined;
[0050] Step S300: acquiring device information of a bound audio output device corresponding to the user interaction subsystem, creating a first audio output thread corresponding to the audio output device based on the device information, and binding the audio output policy of the user interaction subsystem to the first audio output thread;
[0051] Step S400: determining the user interaction subsystem where the user is located according to the audio playback request triggered by the user, determining the corresponding first audio output thread based on the user interaction subsystem, and using the audio output device corresponding to the first audio output thread to perform audio playback.
[0052] Further, in order to better understand the specific implementation of the above steps S200 and S300, that is, how to set the audio output of the user interaction subsystem to use the currently bound audio output device for output after the system detects the audio output device connection event, the embodiment of the present application will be combined with the attached Figure 4 Provide detailed explanation.
[0053] For details, please refer to the attached Figure 4 ,exist Figure 4 The implementation method of the in-vehicle audio output control method in the application scenario shown is that the in-vehicle entertainment system applied to multiple screens in the prior art is generally designed as an entertainment function system based on the rear screen to realize the interaction between the user and the car computer, that is, it is designed as a system independent of the main driving central control system. Figure 4The in-vehicle audio output control method in the application scenario shown may be based on an in-vehicle entertainment system including a first user interaction subsystem 1, a second user interaction subsystem 2 and a third user interaction subsystem 3, wherein the first user interaction subsystem 1 corresponds to the left rear screen, the second user interaction subsystem 2 corresponds to the right rear screen, and the third user interaction subsystem corresponds to AR glasses. Each user interaction subsystem is independent of each other, and the implementation of the in-vehicle audio output control method corresponding to each user interaction subsystem includes the specific implementation steps shown in ①②③④ in the figure. It should be noted that the full name of A2DP is Advanced Audio Distr ibut i on Profile, which refers to the Bluetooth audio transmission model protocol. Specifically, as Figure 4 As shown, the binding process of the audio policy corresponding to the first interactive subsystem 1 includes: ① Bluetooth headset 1 connection event reporting, ② Bluetooth headset 1 A2DP device type and address sending; ③ Creating a corresponding output thread according to the A2DP device type and address; ④ Binding the audio output policy of this user to the output thread corresponding to the Bluetooth address. At this point, the configuration of the audio policy management module 1 of the first interactive subsystem 1 is completed, and then when passenger 1 uses the third-party application of the first interactive subsystem 1 for audio playback, the corresponding Bluetooth headset 1 can be found for audio output. Similarly, the binding process of the audio policy corresponding to the second interactive subsystem 2 includes: ① Bluetooth headset 2 connection event reporting, ② Bluetooth headset 2 A2DP device type and address sending; ③ Creating a corresponding output thread according to the A2DP device type and address; ④ Binding the audio output policy of this user to the output thread corresponding to the Bluetooth address. Similarly, the binding process of the audio policy corresponding to the third interactive subsystem 3 includes: ① reporting the USB audio device insertion event, ② issuing the USB device type and address; ③ creating the corresponding output thread according to the USB audio device type and address; ④ binding the audio output policy of the user to the output thread corresponding to the USB audio device address. It can be understood that the audio policy management module shown in the figure can also configure other audio output policies, such as setting the priority of the first audio output thread and the second audio output thread.
[0054] In actual usage scenarios, the user interaction subsystem can be understood as corresponding one-to-one with the user (user), and the audio output strategy of each user interaction subsystem can be understood as the binding relationship between the user and the audio output thread, that is, for application scenarios in which multiple users simultaneously use the audio services of third-party applications for audio playback, the solution provided by this application takes the user's perspective as the starting point, and can enable multiple users to independently use their own audio output strategies for audio playback, and users can choose to disconnect the audio output device or flexibly switch the audio output channel as needed, so as to enhance the user experience of the in-vehicle entertainment system.
