It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The multi-module upgrade method of the vehicle system described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the multi-module upgrade method of the vehicle system includes the following steps:

[0043] Step S10: when it is detected that there is an update for the vehicle system, a module compression package file of the vehicle system is obtained, and the module compression package file is verified to obtain a file verification result.

[0044] The step S10 comprises:

[0045] Step S11, when it is detected that there is an update for the vehicle system, the upgrade module of the vehicle system is scanned to obtain a module scanning result, and the module to be upgraded in the module scanning result is compressed according to a differential package method to obtain a module compression package file;

[0046] Step S12: download the module compressed package file to obtain a download result, and verify the module compressed package file according to the download result to obtain a file verification result.

[0047] Specifically, in an embodiment of the present invention, the vehicle system generally involves two major components: the central control and the instrument. The central control is further divided into subsystems: an ARM intelligent system part and an mcu1 part; the instrument is further divided into subsystems: an ARM system or an embedded system and an mcu2 part; when it is detected that the vehicle system has an update, the upgrade module of the vehicle system is scanned and processed to obtain a module scanning result (for example, an ARM intelligent system module, an mcu1 module, an ARM system module, and an mcu2 module), and the module to be upgraded in the module scanning result is compressed according to a specific command mode (for example, a differential packet mode) to obtain a module compression package file, wherein the specific command mode part code can be:

[0048] #Downgrade differential packet processing;

[0049] #rm update.zip;

[0050] #. / build / tools / releasetools / ota_from_target_files-v--block--override_timestamp-pout / host / linux-x86 / -kbuild / make / target / product / security / testk ey-inew.zip old.zip update.zip;

[0051] #Incremental differential packet processing;

[0052] #rm update.zip;

[0053] . / build / make / tools / releasetools / ota_from_target_files.py-pout / target / product / qssi / obj / PACKAGING / otatools_intermediates / otatools k build / make / target / product / security / testkey-vi old.zip new.zip update.zip.

[0054] Among them, the module compressed package file has a corresponding compilation command, and an ota package is generated during compilation, which is similar to the compilation command: source build / envsetup.sh, lunch trinket-userdebug, lunch trinket-user, . / build.sh dist-j16 / / n represents the number of CPU threads, . / build.sh dist-j32 2>&1|tee make_log.txt; after obtaining the module compressed package file, the module compressed package file needs to be downloaded to obtain a download result. If the download result is that the download is completed, the module compressed package file is verified according to the download result to obtain a file verification result. The specific verification process is to calculate the hash value of the module compressed package file according to the download result to obtain a target hash value, and compare the target hash value with the cloud hash value corresponding to the module compressed package file; if the target hash value is consistent with the cloud hash value, the file verification result is determined to be a verification pass; if the target hash value is inconsistent with the cloud hash value, the file verification result is determined to be a verification failure. The purpose of verification is to ensure the integrity of the upgrade file, prevent file anomalies during the download process, and prevent upgrade failure. The present invention packages each upgrade module into a compressed file, and only needs to perform a complete verification once after background download, without the need for multiple verification processes, thereby improving file verification efficiency.

[0055] Step S20: If the file verification result is that the verification is passed, the module compression package file is decompressed and identified to obtain the file information to be upgraded.

[0056] The step S20 comprises:

[0057] Step S21: If the file verification result is that the verification is passed, the module compression package file is decompressed to obtain multiple files to be upgraded;

[0058] Step S22: performing identification processing on the version information of all the files to be upgraded to obtain a version identification result, and obtaining corresponding file information to be upgraded according to the version identification result.

[0059] Specifically, if the file verification result is that the verification is passed, the module compressed package file is decompressed to obtain multiple files to be upgraded; then the number of files to be upgraded needs to be identified. Generally, the firmware package is a compressed file, which needs to be decompressed locally during the upgrade. Then, according to the version information in the decompressed package, the current version information is compared to determine which files need to be upgraded or all files need to be upgraded. Specifically, the version information of all the files to be upgraded is identified to obtain a version identification result. For example, the upgrade package contains the CurrentVersion.txt document, which contains the corresponding version information description, such as: Z6001.2025.02.12_09.29, Z6001_N32V1.02D2, and obtain the corresponding file information to be upgraded according to the version identification result; then, it is necessary to determine whether there are multiple files to be upgraded, specifically, compare all file version information of the file information to be upgraded with the current version information of all the files to be upgraded; if all file version information is consistent with the corresponding current version information, then it is determined that the file information to be upgraded does not contain any file to be upgraded; if there are multiple file version information that are inconsistent with the corresponding current version information, then it is determined that the file information to be upgraded contains multiple files to be upgraded.

[0060] Step S30: If the to-be-upgraded file information indicates that there are multiple to-be-upgraded files, the multiple to-be-upgraded files are synchronously upgraded to obtain an upgrade result, and the vehicle system is restarted according to the upgrade result to obtain a target version of the vehicle system.

[0061] The step S30 comprises:

[0062] Step S31: if the to-be-upgraded file information indicates that there are multiple to-be-upgraded files, then a multi-task mechanism is started, and the to-be-upgraded files are synchronously upgraded according to the multi-task mechanism to obtain an upgrade result;

[0063] Step S32: If the upgrade result is that all the files to be upgraded have completed upgrading, the vehicle system is restarted according to the upgrade result to obtain the vehicle system of the target version.

[0064] Specifically, in an embodiment of the present invention, if the file information to be upgraded indicates that there are multiple files to be upgraded, the multi-tasking mechanism is started, and the files to be upgraded are synchronously upgraded according to the multi-tasking mechanism to obtain an upgrade result. The corresponding upgrade process is that the upgrade process is divided into system upgrade and other module upgrade. After the system upgrade process update_engine is started, it starts to read the update system files in the decompressed package for upgrading. At the same time, it can inform the MCU or instrument through the protocol, and then start the corresponding service to start transmitting the corresponding upgrade file, inform the MCU or instrument to start receiving the upgrade file, and then upgrade; if the upgrade result is All the files to be upgraded have been upgraded, and to determine whether all the files to be upgraded have been upgraded, the vehicle system will display the corresponding upgrade progress when upgrading, and the upgrade of other modules MCU or instrument will have a corresponding upgrade progress status notification defined; after that, the vehicle system is restarted according to the upgrade result to obtain the target version of the vehicle system; after the upgrade of each module is completed, the present invention only needs to do an overall restart once, without restarting each module separately, simplifying the process and saving time; and the version information of each module in the compressed package is compared with the current module version information, and only the difference is upgraded, and no upgrade is required if there is no difference, and the mechanism is flexible.

[0065] Furthermore, if Figure 2 As shown, based on the multi-module upgrade method of the vehicle system, the present invention also provides a multi-module upgrade system of the vehicle system, wherein the multi-module upgrade system of the vehicle system includes:

[0066] The file verification module 51 is used to obtain the module compression package file of the vehicle system when it is detected that there is an update of the vehicle system, and to verify the module compression package file to obtain a file verification result;

[0067] A file identification module 52 is used to decompress and identify the module compressed package file to obtain the file information to be upgraded if the file verification result is that the verification is passed;

[0068] The file upgrade module 53 is used to synchronously upgrade the multiple files to be upgraded if the file information to be upgraded indicates that there are multiple files to be upgraded, obtain an upgrade result, and restart the vehicle system according to the upgrade result to obtain a target version of the vehicle system.

[0069] Furthermore, if Figure 3 As shown, based on the multi-module upgrade method of the vehicle system, the present invention also provides a terminal, which includes a processor 10, a memory 20 and a display 30.

[0071] In some embodiments, the processor 10 may be a central processing unit (CPU), a microprocessor or other data processing chip, used to run the program code or process data stored in the memory 20, such as executing a multi-module upgrade method of the vehicle system.

[0072] In some embodiments, the display 30 may be an LED display, a liquid crystal display, a touch-sensitive liquid crystal display, an OLED (Organic Light-Emitting Diode) touch device, etc. The display 30 is used to display information on the terminal and to display a visual user interface.
