Description

Technical Field

[0001] The present invention relates to the field of in-vehicle audio integration technology, and in particular to an in-vehicle audio microservice communication method, system, device, and vehicle. Background Art

[0002] With the advancement of vehicle intelligence and growing awareness of copyright, the number of in-car audio entertainment services, such as Kuwo Music, Himalaya Radio, QQ Music, and K-Go, is increasing. Each application holds distinct audio copyrights. Consequently, car owners are increasingly seeking in-car audio applications that integrate mainstream audio resources. The demand for technical resource integration and rapid integration and de-listing is also growing. Furthermore, the communication between in-car applications (such as voice, navigation, and scene modes) is becoming increasingly close to ensure a superior in-car entertainment experience.

[0003] Current market issues: Most in-car systems rely on a single, integrated entertainment application solution and leverage a single company's audio resources. If other audio resources are needed, arbitrary application installation is generally prohibited to ensure in-car safety. Consequently, the user experience relies primarily on connecting the phone to the car, using Bluetooth music, Android Auto, Car Play, and other methods. This approach offers a fragmented and inadequate in-car system experience. Furthermore, the heavy reliance on the phone does not align with the future concept of providing users with a third space in the connected car.

[0004] If the cooperative relationship is terminated, the audio application of the car system released on the market may become unusable. The only solution is to upgrade it. However, the upgrade package is too large to be upgraded differentially, and many unstable problems will occur after the upgrade, which is very troublesome. Summary of the Invention

[0005] In order to solve the problems existing in the above-mentioned prior art, the present invention provides an in-vehicle audio microservice communication method, including an audio microservice session management module, an audio microservice identification and loading module, an audio microservice session controller, an audio microservice session browser, an audio microservice adapter and several audio microservices; the audio microservice session management module is used to maintain and manage the life cycle of each audio microservice, including the activation state and the audio focus state; the audio microservice identification and loading module is used to identify the intent filter defined in the manifest file of each audio microservice; the audio microservice session controller is used to provide audio playback control function to external callers; the audio microservice session browser is used to provide audio data browsing function to external callers; the audio microservice adapter is used to provide adaptation development templates for various audio application development; the audio microservice provides an interface corresponding to the audio microservice adapter.

[0006] The audio microservice includes at least a first audio microservice and a second audio microservice; the audio microservice session browser provides the audio source data of all current microservices to the external caller; the external caller seizes the audio focus through the first audio microservice, initiates playback, and feeds back the playback status, audio information, and playlist information of the first audio microservice to the audio microservice session management module; when the audio microservice session management module receives a signal to switch the audio source, the first audio microservice releases the focus, the second audio microservice seizes the focus, calls the second audio microservice for playback, and feeds back the playback status, audio information, and playlist information of the second audio microservice to the audio microservice session management module.

[0007] By setting up several audio microservices, each audio microservice can correspond to an audio source provided by an external caller, so that the various audio sources can be integrated together and the audio source can be switched by switching the audio microservice.

[0008] Furthermore, the system also includes audio microservice identification and verification, including an audio microservice configuration list module and an audio microservice loading security authentication module. The audio microservice configuration list is used to record the list of audio microservices that can be used by the microservice platform; the audio microservice loading security authentication module is used by each audio microservice to authenticate the microservice platform. Through two-way authentication between the audio microservice and the microservice platform, the user's vehicle is protected from external programs.

[0009] Furthermore, the audio microservice loading security authentication module includes an id authentication submodule, a platform authentication submodule and / or a signature authentication submodule; the id authentication submodule identifies the process id of the current microservice platform through each audio microservice for authentication, to allow the microservice platform to call the data and capabilities in the microservice; the platform authentication submodule identifies the signature platform permission of the current microservice platform through each audio microservice to allow the microservice platform to call the data and capabilities in the microservice; the signature authentication submodule identifies the signature of the current microservice platform through each audio microservice to allow the microservice platform to call the data and capabilities in the microservice.

[0010] Furthermore, if any of the sub-modules passes the verification, the microservice platform is authenticated.

[0011] Furthermore, the installation and uninstallation of the audio microservice monitor the broadcast events of the system application installation and uninstallation. When the audio microservice is installed, it enters the audio microservice loading security authentication module and the audio microservice configuration list module for review. After the review is passed, it enters the session management module to ensure the rapid listing of the audio source.

[0012] Furthermore, by actively pulling cloud configuration or cloud push configuration, the audio microservice configuration list is updated; when the list is updated, the microservices in the session management module are reviewed and the removed microservices are cleared; when the audio microservice is uninstalled, the removed microservices in the session management module are cleared to ensure the rapid removal of the audio source.

[0013] Furthermore, there is an audio microservice initialization process, which asynchronously executes the startup of the last used audio microservice and the identification and verification of all audio microservices. If the last used audio microservice is unavailable, other available audio microservices are started. When the audio source is off the shelf, other audio sources can be played.

[0014] Also provided is an in-vehicle audio microservice communication system, which uses the above method and includes an audio microservice session management module, an audio microservice identification and loading module, an audio microservice session controller, an audio microservice session browser, an audio microservice adapter and several audio microservices; the audio microservice session management module is used to maintain and manage the life cycle of each audio microservice, including the activation state and the audio focus state; the audio microservice identification and loading module is used to identify the intent filters defined in the manifest file of each audio microservice; the audio microservice session controller is used to provide audio playback control function to external callers; the audio microservice session browser is used to provide audio data browsing function to external callers; the audio microservice adapter is used to provide adaptation development templates for various audio application development; the audio microservice provides an interface corresponding to the audio microservice adapter.

[0015] A computing device is also provided, comprising a processor and a memory, wherein the memory stores a code for executing the above method.

[0016] A vehicle is also provided, using the above method.

[0017] The present invention fuses and integrates multiple audio resources to provide users with a good and unified user experience.

[0018] When the audio partner terminates the cooperation, the present invention can disable the audio microservice by updating the microservice configuration table to ensure rapid removal from the shelves.

[0019] As long as the present invention matches the application of the in-vehicle audio microservice architecture, it can be downloaded and quickly put on the shelf through the in-vehicle application store, ensuring that users can enjoy new resources.

[0020] The present invention provides an accurate two-way signature verification mechanism, and there is a two-way verification logic between the audio microservice architecture and the microservice to ensure that the user's vehicle is not affected by external programs.

[0021] Other in-vehicle applications of the present invention can use the capabilities provided by the audio microservice architecture to call playback control capabilities and data browsing capabilities, providing users with cross-application (such as instrument display, steering wheel control, voice control, scene control, etc.) experience.

[0022] This invention microservices audio application development, providing a unified development approach and templates through an audio microservice adapter for efficient development. Furthermore, through the audio microservice controller and browser, development costs for callers are reduced, and the external interface is consistent, enabling rapid integration of product experiences across application layers.

The audio microservice configuration list is used to record the list of available audio microservices on the microservice platform; the audio microservice loading security authentication module is used by each audio microservice to authenticate the microservice platform. This two-way authentication between the audio microservice and the microservice platform ensures that the user's vehicle is not affected by external programs.

This invention provides an accurate two-way signature verification mechanism, and two-way verification logic is implemented between the audio microservice architecture and the microservices, ensuring that the user's vehicle is not affected by external programs.

[0054] The audio microservice's installation and uninstallation monitors broadcast events related to system application installation and uninstallation. During installation, the system enters the audio microservice loading security authentication module and the audio microservice configuration list module for review. Once the review is passed, the system enters the session management module, ensuring rapid availability of audio sources. Applications compatible with the in-vehicle audio microservice architecture can be downloaded and quickly available through the in-vehicle app store, ensuring users have access to new resources.

[0055] The audio microservice can be installed and uninstalled by monitoring broadcast events related to system application installation and uninstallation. During installation, the system must re-enter the security authentication module and configuration list module for review. If the review fails, the system cannot enter the session management module for use. If the recognition is successful, the system can enter the session management module and utilize its capabilities within the microservice architecture.

[0056] Example 6:

[0057] This embodiment provides an in-vehicle audio microservice communication method, including an audio microservice session management module, an audio microservice identification and loading module, an audio microservice session controller, an audio microservice session browser, an audio microservice adapter, and several audio microservices; the audio microservice session management module is used to maintain and manage the life cycle of each audio microservice, including the activation state and audio focus state; the audio microservice identification and loading module is used to identify the intent filters defined in the manifest file of each audio microservice; the audio microservice session controller is used to provide audio playback control functions for external callers; the audio microservice session browser is used to provide audio data browsing functions for external callers; the audio microservice adapter is used to provide adaptation development templates for various audio application development; and the audio microservice provides an interface corresponding to the audio microservice adapter.

When facing the termination of cooperation with an audio partner, the present invention can disable the audio microservice by updating the microservice configuration table, ensuring rapid decommissioning.

[0063] See also Figure 3Specifically, the audio microservice configuration list is updated via HTTP and web sockets, actively pulling configurations from the cloud and actively pushing configurations from the cloud. When the list is updated, the session management module must review and remove any microservices that have been removed. When uninstalling the audio microservice, the session management module also removes any removed microservices. However, the configuration list is not updated, ensuring that the removed microservice can continue to function normally the next time it is installed.

[0064] Example 7:

[0065] This embodiment provides an in-vehicle audio microservice communication method, including an audio microservice session management module, an audio microservice identification and loading module, an audio microservice session controller, an audio microservice session browser, an audio microservice adapter, and several audio microservices; the audio microservice session management module is used to maintain and manage the life cycle of each audio microservice, including the activation state and audio focus state; the audio microservice identification and loading module is used to identify the intent filters defined in the manifest file of each audio microservice; the audio microservice session controller is used to provide audio playback control functions for external callers; the audio microservice session browser is used to provide audio data browsing functions for external callers; the audio microservice adapter is used to provide adaptation development templates for various audio application development; and the audio microservice provides an interface corresponding to the audio microservice adapter.

[0071] There is also an audio microservice initialization process, which asynchronously executes the startup of the last used audio microservice and the identification and verification of all audio microservices. If the last used audio microservice is unavailable, other available audio microservices are started. If the audio source is off the shelf, other audio sources can be played.

[0072] See also Figure 4 Specifically, during the boot process, the microservice needs to be identified and loaded through initialization. Two paths are used to process the last used audio microservice and the full set of microservice identification verification respectively. The purpose of this is to efficiently ensure the normal audio usage process and quickly enter the Last Mode mode (a common function for car audio. If the last audio playback status needs to be restored, the playback function should be performed. If it is not playing, the audio information should be restored silently.)

[0076] This embodiment is a computing device, including a processor and a memory, wherein the memory stores codes for executing the method in the above embodiment.

[0077] The processor may be a multi-core processor or may include multiple processors. In some embodiments, the processor may include a general-purpose main processor and one or more special coprocessors, such as a graphics processing unit (GPU), a digital signal processor (DSP), etc. In some embodiments, the processor may be implemented using customized circuits, such as application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs).

[0078] The memory may include various types of storage units, such as system memory, read-only memory (ROM), and permanent storage devices. ROM may store static data or instructions required by the processor or other modules of the computer. The permanent storage device may be a readable and writable storage device. The permanent storage device may be a non-volatile storage device that does not lose stored instructions and data even if the computer is powered off. In some embodiments, the permanent storage device uses a large-capacity storage device (such as a magnetic or optical disk, flash memory) as the permanent storage device. In other embodiments, the permanent storage device may be a removable storage device (such as a floppy disk, optical drive).
