Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to an audio playback method, terminal device, and storage medium for a smart cockpit. Background Technology

[0002] Currently, the automotive industry is evolving from mechanization to electrification, connectivity, intelligence, and sharing, and moving from the traditional industrial era to the digital age. As a crucial component of future intelligent vehicles, the intelligent cockpit has increasingly diverse functional requirements, necessitating a growing number of audio systems. Conflicts may arise when different audio systems play audio, a problem that existing solutions cannot resolve. For example, when a vehicle includes multiple speakers, and it's necessary to dynamically configure navigation audio to be mixed or played exclusively on one speaker while other speakers remain unaffected, existing solutions are no longer sufficient, and may even be impossible, to achieve this simply. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes an audio playback method, terminal device, and storage medium for smart cockpits.

[0004] The specific plan is as follows:

[0005] An audio playback method for a smart cockpit includes the following steps:

[0006] For each audio system in the cockpit, a corresponding first audio interaction matrix is ​​constructed; the rows and columns of the first audio interaction matrix are the audio types that the audio system can receive, and the elements in the first audio interaction matrix represent the audio strategy adopted when the corresponding row and column audio types are received simultaneously.

[0007] When the audio system receives two types of audio data at the same time, it generates an audio playback request based on the audio strategy contained in the first audio interaction matrix and sends it to the audio control module.

[0008] Construct a second audio interaction matrix corresponding to the audio control module; the rows and columns of the second audio interaction matrix are each channel contained in the audio chip, and the elements in the second audio interaction matrix represent the audio strategy adopted when the audio playback request corresponding to the channel in the corresponding row and column is received simultaneously;

[0009] When the audio control module receives audio playback requests from two audio systems simultaneously, it controls the audio chip to play audio based on the audio strategy contained in the second audio interaction matrix.

[0010] Furthermore, audio strategies include exclusive access, concurrency, and rejection.

[0011] Furthermore, a configuration file containing the mapping relationship between audio types and channels is constructed and pre-configured within the audio system. When the audio system needs to send an audio playback request, it searches for the corresponding channel from the mapping relationship based on the audio type of the audio in the audio playback request and adds the found channel to the audio playback request.

[0012] Furthermore, when the audio system is AAOS, its configuration file is an XML file.

[0013] Furthermore, it also includes constructing an audio channel strategy corresponding to the audio control module, which records the speakers required when the audio chip plays the audio corresponding to each channel.

[0014] An audio playback terminal device for a smart cockpit includes a processor, a memory, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the method described above in the embodiments of the present invention.

[0015] A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described above in the embodiments of the present invention.

[0016] The present invention adopts the above technical solution and is applicable to intelligent application scenarios of multiple audio systems in smart cockpits. It can flexibly control the interaction of all audio playback according to the in-vehicle scenario. Attached Figure Description

[0017] Figure 1 The diagram shown is a flowchart of a method according to an embodiment of the present invention. Detailed Implementation

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1:

[0021] This invention provides an audio playback method for smart cockpits, such as... Figure 1 As shown, the method includes the following steps:

[0022] S1: For each audio system in the cockpit, construct its corresponding first audio interaction matrix; the rows and columns of the first audio interaction matrix are the audio types that the audio system can receive, and the elements in the first audio interaction matrix represent the playback strategy adopted when the corresponding audio types in the row and column are received simultaneously.

[0023] The aforementioned audio system refers to any audio system in the smart cockpit with an independent control chip. Different audio systems are independent of each other, such as the AAOS audio system of the IVI (In-Vehicle Infotainment) central control screen, the audio system of the instrument panel, the DSP audio system, etc., and there are no restrictions here.

[0024] The rows and columns of the first audio interaction matrix correspond to all audio types that the terminal of each audio system can generate. Different audio systems have different audio types due to the different terminals they operate on, and each audio system corresponds to a separate first audio interaction matrix. Table 1 shows a schematic diagram of the first audio interaction matrix, where the rows and columns are the same, representing audio types (MUSIC, NAVIGATION, VOICE_COMMAND, etc.). The elements in the matrix represent audio strategies. In this embodiment, three audio strategies are set: "Exclusive," "Reject," and "Concurrent." E, R, and C in Table 1 correspond to the three audio strategies, respectively. It should be noted that in practical applications, those skilled in the art can set the audio strategies used according to their needs, and no restrictions are imposed here.

[0025] Table 1

[0026]

[0027] S2: When the audio system receives two types of audio data at the same time, it generates an audio playback request based on the audio strategy contained in the first audio interaction matrix and sends it to the audio control module.

[0028] In one implementation, when the audio system receives data of two audio types simultaneously, it searches for audio strategies in the first audio interaction matrix where the rows and columns are the two audio types respectively, uses the found audio strategy to obtain the audio to be played, and generates a corresponding audio playback request based on the audio to be played.

[0029] In this embodiment, the audio playback request needs to include the audio chip's channels. Therefore, this embodiment also includes constructing a configuration file containing the mapping relationship between audio types and channels, and pre-configuring it within the audio system. When the audio system needs to send an audio playback request, it searches for the corresponding channel from the mapping relationship based on the audio type of the audio in the playback request, and adds the found channel to the audio playback request. When the audio system is AAOS, its configuration file is an XML file. In other embodiments, the configuration file can also be in other formats, such as JOSN format, lightweight databases, etc.

[0030] S3: Construct the second audio interaction matrix corresponding to the audio control module; the rows and columns of the second audio interaction matrix are each channel contained in the audio chip, and the elements in the second audio interaction matrix represent the audio strategy adopted when the audio playback request corresponding to the channel in the corresponding row and column is received simultaneously.

[0031] Based on the first audio interaction matrix, each audio system can process the audio it receives. However, since the smart cockpit contains more than one audio system, when there are more than one audio system, the two audio systems may cause conflicts. Therefore, in this embodiment, a second audio interaction matrix is ​​constructed in the audio control module to resolve this conflict.

[0032] Table 2 shows a schematic diagram of the second audio interaction matrix. The rows and columns are the same, and they are all channel numbers corresponding to the audio chip (that is, the chip contains N channels, and the corresponding second audio interaction matrix is ​​N*N). The elements in the matrix also represent the audio strategy.

[0033] Table 2

[0034]

[0035] S4: When the audio control module receives audio playback requests from two audio systems simultaneously, it controls the audio chip to play audio based on the audio strategy contained in the second audio interaction matrix.

[0036] In this embodiment, the audio control module can, when simultaneously receiving audio playback requests from two audio systems, search for the corresponding audio strategy from the second audio interaction matrix based on the channel numbers contained in the two audio playback requests. It then uses the found audio strategy to obtain the audio to be played and controls the audio chip to play the audio based on this audio. Furthermore, this method can be used for a single audio system or simple audio needs, as well as for multiple audio systems or complex audio needs. When used with two or more audio systems, the audio control module may receive audio playback requests from more than two audio systems simultaneously. Since the second audio interaction matrix can only select an audio strategy based on two requests, it first selects an audio strategy for two of the requests according to the second audio interaction matrix. Then, based on the selected audio strategy result, it selects an audio strategy again according to the second audio interaction matrix along with the third request, and so on.

[0037] It should be noted that both the first and second audio interaction matrices are applications in real-world projects. Therefore, the objects in the first and second audio interaction matrices are designed for the objects that the current module of the project needs to control. Thus, the design can be determined based on the objects that need to be controlled in the actual project or solution application. Currently, the objects typically dealt with are audio types and audio channels. If other objects exist, they can be constructed by referring to the solution principles, such as when dealing with virtual channels.

[0038] Furthermore, since the smart cockpit may contain multiple speakers, this embodiment also includes an audio channel strategy for constructing the audio control module. This audio channel strategy records the speakers required when the audio chip plays the audio corresponding to each channel. It can be that all channels correspond to one speaker, or several channels correspond to one speaker. The specific settings can be configured according to actual needs, and no restrictions are imposed here.

[0039] This solution embodiment formulates different audio interaction strategies based on different audio systems, and also formulates audio interaction strategies between different audio systems, which are applied to intelligent application scenarios in intelligent cockpits.

The general-purpose processor can be a microprocessor or any conventional processor. This processor serves as the control center of the audio playback terminal device for the smart cockpit, connecting all parts of the audio playback terminal device for the smart cockpit via various interfaces and lines.

[0044] The memory can be used to store the computer programs and / or modules. The processor implements various functions of the audio playback terminal device for the smart cockpit by running or executing the computer programs and / or modules stored in the memory and calling data stored in the memory.

[0045] The present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the method described in the embodiments of the present invention.
