[0024] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0026] See also Figure 1 , is a schematic diagram of the architecture of a system for upgrading a vehicle system provided in an embodiment of the present application. The architecture of the system may include a terminal 10 and a server 20.

[0027] Among them, the terminal 10 can also be called user equipment (UE for short). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as on a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). It can also be called a user terminal, terminal equipment, access terminal equipment, vehicle-mounted terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, mobile terminal, wireless communication equipment, UE agent or UE device, etc. The terminal can be fixed or mobile, etc. Its specific form can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a vehicle-mounted terminal device, a wireless terminal in a smart home, a wearable terminal device, etc. It is an entity on the user side for receiving or transmitting signals. In an embodiment of the present application, the terminal 10 can receive the version number of the upgrade package sent by the server 20, and compare the version number with the current version number of the vehicle system. If the version number is higher than the current version number of the vehicle system, the system update information is pushed on the system interface to prompt the user to upgrade the vehicle system and obtain the upgrade package sent by the server 20. Furthermore, the terminal 10 can obtain the resource files in the upgrade package and upgrade a single partition of the vehicle system. For the sake of simplicity of description, the embodiment of the present application only shows one terminal 10. In an actual scenario, there may be one or more users who receive the version number of the upgrade package sent by the server 20 and obtain the upgrade package sent by the server 20. Therefore, the number of terminals 10 may also be one or more, and the embodiment of the present application does not impose any limitation.

[0028] The server 20, which can also be called a backend server, a business server, etc., can be used to provide various business services to users. For example, in this application, the system version number and the system upgrade package can be sent to the user, and the system update service can be provided to the user.

[0029] See also Figure 2 , is a flow chart of a method for upgrading a vehicle system provided in an embodiment of the present application, comprising the following steps:

[0030] S201, obtaining an upgrade package, extracting upgrade files in the upgrade package, and upgrading the second system of the vehicle system.

[0031] For example, after obtaining the upgrade package, the second system can be upgraded by reading the payload.bin file in the upgrade package that records the data for upgrading the second system, and using the background upgrade program update_engine. The entire update process is completed in the background and is invisible to users.

[0032] The upgrade package is used to upgrade the vehicle system, and the vehicle system includes a running first system and a non-running second system.

[0033] In a possible implementation, the user may obtain the upgrade package through Over The Air (OTA) technology.

[0034] For example, the upgrade package can be obtained through SMS. The user sends a short message to the server through the terminal to request the server to download the upgrade package service. The server sends the download data to the user's terminal device through SMS.

[0035] Alternatively, the upgrade package can be obtained in a browser-based manner. The user logs in to the server, searches for the application menu, and downloads the corresponding upgrade package from the network backend server as needed;

[0036] Alternatively, the developer may send a link notification of the upgrade package download to the terminal user via SMS or mobile email according to business needs, and the user clicks the link to realize remote automatic upgrade. The embodiment of the present application does not impose any limitation on the method of obtaining the upgrade package.

[0037] Through the above method, it is easier for users to obtain upgrade packages. By upgrading the second system that is not running in the vehicle system, a silent and seamless upgrade of the vehicle system can be achieved.

[0038] Optionally, obtaining the upgrade package includes:

[0039] In response to a confirmation instruction from a user to upgrade the vehicle system, obtaining an upgrade package and verifying the upgrade package;

[0040] If the verification passes, mapping the upgrade package into the memory;

[0041] If the verification fails, the system upgrade is terminated.

[0042] Optionally, the verifying the upgrade package includes:

[0043] The upgrade package is subjected to an integrity check and a signature check, wherein the integrity check is used to ensure the integrity of the upgrade package, and the signature check is used to ensure that the upgrade package matches the vehicle system.

[0044] For example, the integrity check of the upgrade package is performed using Message Digest Algorithm 5 (MD5 for short). The md5 value in the upgrade package is obtained and compared with the md5 value of the original upgrade package pre-stored on the server. If the md5 value in the upgrade package is the same as the md5 value of the original upgrade package pre-stored on the server, the upgrade package is complete and the integrity check passes; if the md5 value in the upgrade package is different from the md5 value of the original upgrade package pre-stored on the server, the upgrade package is incomplete and the integrity check fails. The algorithm for performing integrity check on the upgrade package can also be Secure Hash Algorithm 2 (SHA-2 for short) or Message Authentication Code (MAC for short), etc., which is not limited in any way in the embodiments of the present application.

[0045] At the same time, the upgrade package obtained by the above method will have a digital signature, which is a digital string that identifies the server identity. The terminal can find the digital signature of the current system installation package and compare it with the digital signature in the upgrade package to determine whether the digital signatures are consistent. If the digital signatures are consistent, the upgrade package matches the vehicle system and the signature verification of the upgrade package passes; the terminal can also obtain a digital signature from the server and compare it with the digital signature in the upgrade package to determine whether the digital signatures are consistent. The embodiment of the present application does not impose any restrictions on the method of obtaining the digital signature.

[0046] By performing integrity verification and signature verification on the upgrade package, the integrity of the upgrade package can be guaranteed, and the upgrade package can also be guaranteed to match the vehicle system.

[0047] S202, creating a temporary mounting directory under a preset directory, and mounting a single partition of the vehicle system to the temporary mounting directory.

[0048] For example, the default directory can be the / mnt / tmp directory under the root directory where the system is located. You can use the subdirectory creation command mkdir to create a temporary mount directory resc under the default directory / mnt / tmp / , and use the partition mount command mount to mount the single partition resc storing voice resources in read-write mode to the temporary mount directory mnt / tmp / resc.

[0049] The single partition is used to store files required for running applications in the vehicle system, and the temporary mount directory is used to read and write the single partition. For example, the single partition can be used to store voice resources, downloaded pictures, music and user photos, or offline map data, etc. At the same time, the single partition of the vehicle system can be one or more, and this embodiment of the application does not impose any limitation on this.

[0050] Optionally, before creating a temporary mount directory under the preset directory, the method further includes:

[0051] The command script and command parser in the upgrade package are stored in the preset directory.

[0052] The command script is used to store commands related to system upgrade, and the command parser is used to parse the commands in the command script.

[0053] For example, the command script may be updater-script, and the command parser may be update-binary.

[0054] S203, extracting resource files of the upgrade package, and storing the resource files in the temporary mounting directory.

[0055] Optionally, extracting resource files from the upgrade package and storing the resource files in the temporary mount directory includes:

[0056] Obtain an extraction command in the command script, parse the extraction command through the command parser, extract resource files in the upgrade package according to the extraction command, and store the resource files in the temporary mount directory.

[0057] For example, the package_extract_dir("RESOURCE"," / mnt / tmp / resc") command can be extracted from the command script, and the command is parsed by the command parser to replace the resource files in the RESCOURCE directory in the upgrade package with the temporary mount directory. The directory structure of the RESCOURCE directory in the upgrade package is the same as that of the temporary mount directory.

[0058] Optionally, the resource file includes voice resources, map offline resources, or a database required for application operation.

[0059] S204: Synchronize the resource files in the temporary mount directory to the single partition.

[0060] Optionally, synchronizing the resource files in the temporary mount directory to the single partition includes:

[0061] Determine whether the upgrade package is a full upgrade package or a differential upgrade package, the resource files of the full upgrade package include all files required for upgrading the single partition, and the resource files of the differential upgrade package include supplementary files required for upgrading the single partition;

[0062] If the upgrade package is a full upgrade package, all files in the single partition are replaced with resource files in the temporary mount directory;

[0063] If the upgrade package is a differential upgrade package, the resource files under the temporary mount directory are added to the single partition.

[0064] In a possible implementation, if the upgrade package is a differential upgrade package, and the differential upgrade package only contains resource files for upgrading a single partition, the purpose of upgrading only a single partition can be achieved without upgrading the first system or the second system.

[0065] By synchronizing the resource files in the temporary mount directory to the single partition, a silent and seamless upgrade of the single partition can be achieved.

[0066] Optionally, the method further includes: modifying the startup flag of the vehicle system, setting the second system as the target object after the system is restarted, and setting the first system as a non-startable object.

[0067] For example, when the system has not been updated, the first system is running, in a startable, successful and active state, while the second system as a backup system is not currently running, in a startable, successful and dormant state;

[0068] While the systems are being updated, the first system is not affected and remains in a bootable, successful and active state, while the second system is being updated and is now in an unbootable, unsuccessful and dormant state;

[0069] When the system update is completed but has not been restarted, the first system is still running, but it should be set to the bootable, successful and dormant states, indicating that although the first system can be started and has run successfully, it is now in a dormant state, that is, the first system is set as a non-bootable object, and the first system will not be started first after the system is restarted; while the second system has been updated at this time, it should be set to the bootable and active states, that is, the second system is set as the target object after the system restarts, indicating that the second system will be started first after the system restarts. Because the second system has not yet run, the second system is in a non-successful state at this time;

[0070] After the system restarts successfully, the second system is set to a bootable, successful, and active state.

[0071] Through the above method, the startup flags of the first system and the second system can be modified in time to ensure that the updated second system is applied after the system is restarted.

[0072] Optionally, before obtaining the upgrade package, the method further includes:

[0073] Receiving the version number of the upgrade package, and comparing the version number with the current version number of the vehicle system;

[0074] If the version number is higher than the current version number of the vehicle system, system update information is pushed on the system interface to prompt the user to upgrade the vehicle system;

[0075] If the version number is not higher than the current version number of the vehicle system, continue to loop to detect whether there is system update information.
