[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0043] Example 1

[0044] Please see Figure 1 This is a flowchart of a vehicle-mounted device network upgrade method provided in the first embodiment of the present invention. This vehicle-mounted device network upgrade method can be applied to any device or system, and includes the following steps:

[0045] Step S10: Obtain the vehicle network upgrade request sent by the intelligent vehicle device, and determine the target kernel data based on the preview kernel file in the vehicle network upgrade request;

[0046] The cloud server sends a network upgrade message to the intelligent vehicle device. After receiving the network upgrade message, the intelligent vehicle device sends an in-vehicle network upgrade request. The in-vehicle network upgrade request includes the current kernel version (WebView kernel version) and the target upgrade version. Based on the in-vehicle network upgrade request, the cloud server obtains the corresponding version data from the preset preview kernel version library to obtain the target kernel data.

[0047] Optionally, the target kernel data is determined based on the preview kernel file in the vehicle network upgrade request, including:

[0048] The current kernel version and the target upgrade version in the vehicle network upgrade request are obtained, and the current kernel version and the target kernel upgrade version are combined to obtain kernel combination information; wherein, by combining the current kernel version and the target kernel upgrade version, the matching operation between the subsequent kernel combination information and the preview kernel version library is effectively facilitated.

[0049] The kernel combination information is matched with the preview kernel version library in the cloud server to obtain the target kernel data, configuration file and dependency library. The target kernel file, configuration file and dependency library are then combined to obtain the target kernel data. The preview kernel version library stores the correspondence between different kernel combination information and the corresponding target kernel data, configuration file and dependency library.

[0050] Furthermore, before obtaining the vehicle network upgrade request sent by the intelligent vehicle device, the following steps are also included:

[0051] The system acquires an environmental image of the user's vehicle corresponding to the intelligent vehicle device, and performs vehicle recognition on the environmental image to obtain the identified vehicle; wherein, the system takes an image of the environment in which the intelligent vehicle device is currently located to obtain an environmental image, and performs vehicle recognition on the vehicles in the environmental image to obtain the model of each identified vehicle.

[0052] The user's vehicle is matched with the identified vehicle, and the associated vehicle is determined based on the vehicle matching result; wherein, the model of the user's vehicle is matched with the model of the identified vehicle, and based on the vehicle matching result, the identified vehicle with the same model as the user's vehicle is determined as the associated vehicle.

[0053] Send a kernel version request message to the associated vehicle and receive a kernel version response to the kernel version request message; wherein, by sending a kernel version request message to the associated vehicle, the kernel version information of the associated vehicle is obtained.

[0054] The kernel version in the kernel version response is matched with the current kernel version of the intelligent vehicle device. Specifically, by comparing the kernel version in the kernel version response with the current kernel version, it is determined whether the version of the preview kernel in the associated vehicle is higher than the kernel version of the intelligent vehicle device. If the version of the preview kernel in the associated vehicle is higher than the kernel version of the intelligent vehicle device, it is determined that the kernel version in the kernel version response matches the current kernel version successfully.

[0055] If the kernel version in the kernel version response matches the current kernel version, then the intelligent vehicle device is controlled to send the vehicle network upgrade request.

[0056] In this step, if the preview kernel version in the associated vehicle is lower than the kernel version of the smart vehicle device, a network upgrade prompt will be sent to the associated vehicle. If the preview kernel version in the associated vehicle is the same as the kernel version of the smart vehicle device, no network upgrade prompt needs to be sent.

[0057] Step S20: Generate a preview kernel resource package based on the target kernel data, and send the preview kernel resource package to the intelligent vehicle device for decompression to obtain the preview kernel decompressed file;

[0058] The cloud server re-signs the target kernel data to generate a preview kernel resource package containing the new kernel version. In addition to the new kernel file, the preview kernel resource package also contains the necessary configuration files and dependency libraries to ensure that the smart vehicle device can correctly load and use the new kernel.

[0059] Optionally, a preview kernel resource package is generated based on the target kernel data, including:

[0060] The signature information of the cloud server and the preview kernel repository is obtained to obtain the server signature and repository signature. The target kernel data is then re-signed based on the server signature and repository signature to obtain the preview kernel resource package. Specifically, re-signing the target kernel data using the server signature and repository signature facilitates the decompression and verification of the preview kernel resource package by the intelligent vehicle device. The cloud server pushes the generated preview kernel resource package to the intelligent vehicle device requesting the upgrade. After receiving the resource package, the vehicle device verifies and decompresses it to obtain the decompressed preview kernel file.

[0061] Step S30: Upgrade the preview kernel in the intelligent vehicle device according to the preview kernel decompression file to obtain the preview upgraded kernel, and perform network testing on the preview upgraded kernel to obtain the network upgrade result of the intelligent vehicle device;

[0062] The process involves determining preview compatibility. If the preview kernel decompression file can be installed directly, the preview version can be upgraded directly. If the installation fails, the previewer files (system / app / webview) must be deleted before installation. In this step, after the kernel replacement is complete, the smart vehicle device restarts the previewer service to make the new kernel effective. After restarting, a network test is performed on the upgraded preview kernel to check if the smart vehicle device has successfully upgraded online. If the network upgrade is successful, the smart vehicle device can use the new version of the preview kernel to load web pages, improving page loading speed and compatibility.

[0063] Optionally, the preview kernel in the intelligent vehicle device is upgraded according to the preview kernel decompression file to obtain the preview upgraded kernel, including: replacing the current kernel file in the preview kernel with the target kernel file in the intelligent vehicle device, and restarting the preview network service according to the configuration file and the dependent libraries to obtain the preview upgraded kernel.

[0064] Furthermore, network testing is performed on the preview upgrade kernel to obtain the network upgrade results of the intelligent vehicle device, including:

[0065] The preview upgrade kernel is controlled to make a network connection according to a preset URL, and the webpage is displayed and the loading time of the displayed webpage is obtained. The preset URL can be set according to the requirements. By controlling the preview upgrade kernel to make a network connection, the network loading speed of the preview upgrade kernel can be effectively tested.

[0066] The preview upgrade kernel is controlled to download a preset application in the displayed webpage and the download time of the preset application is obtained; wherein, the preset application can be set according to needs, and by downloading the preset application in the displayed webpage, the network download speed of the preview upgrade kernel can be effectively tested;

[0067] The preview upgrade kernel is controlled to perform webpage redirection on the displayed webpage, obtain the redirected webpage, and acquire the response time of the redirected webpage; wherein, by performing webpage redirection on the displayed webpage, the network response speed of the preview upgrade kernel can be effectively tested;

[0068] The network upgrade result is generated based on the loading time, the download time, and the response time.

[0069] Furthermore, the network upgrade result is generated based on the loading time, the download time, and the response time, including:

[0070] The total network time is obtained by weighting the loading time, download time, and response time; wherein the weighting coefficients of loading time, download time, and response time during the weighting process can be set according to requirements;

[0071] If the total network time is less than or equal to the time threshold, the network upgrade of the intelligent vehicle device is determined to be successful; if the total network time is greater than the time threshold, the network upgrade of the intelligent vehicle device is determined to be unsuccessful; wherein, the time threshold can be set according to requirements.

[0072] In this embodiment, based on the preview kernel file in the vehicle network upgrade request, the target kernel data can be automatically determined. Based on the target kernel data, a preview kernel resource package can be effectively generated. By decompressing the preview kernel file, the preview kernel in the smart vehicle device can be effectively upgraded to obtain the preview upgraded kernel, thereby achieving the network upgrade effect of the smart vehicle device without upgrading the vehicle system. This prevents incompatibility issues with other applications on the smart vehicle device and improves the user experience.

[0077] The kernel combination information is matched with the preview kernel version library in the cloud server to obtain the target kernel data, configuration file and dependency library, and the target kernel file, configuration file and dependency library are combined to obtain the target kernel data.

[0078] Furthermore, the data determination module 10 is also used to: acquire an environmental image of the user's vehicle corresponding to the intelligent vehicle device, and perform vehicle recognition on the environmental image to obtain the identified vehicle;

[0079] The user's vehicle is matched with the identified vehicle, and the associated vehicle is determined based on the vehicle matching result.

[0080] Send a kernel version request message to the associated vehicle and receive a kernel version response in response to the kernel version request message;

[0081] Match the kernel version in the kernel version response with the current kernel version of the intelligent vehicle device;

[0082] If the kernel version in the kernel version response matches the current kernel version, then the intelligent vehicle device is controlled to send the vehicle network upgrade request.

[0083] The decompression module 11 is used to generate a preview kernel resource package based on the target kernel data, and send the preview kernel resource package to the intelligent vehicle device for decompression to obtain a preview kernel decompression file.

[0084] Optionally, the decompression module 11 is further configured to: obtain the signature information of the cloud server and the preview kernel repository, obtain the server signature and the repository signature, and re-sign the target kernel data according to the server signature and the repository signature to obtain the preview kernel resource package.

[0085] The kernel upgrade module 12 is used to upgrade the preview kernel in the intelligent vehicle device according to the preview kernel decompression file to obtain the preview upgraded kernel, and to perform network testing on the preview upgraded kernel to obtain the network upgrade result of the intelligent vehicle device.

[0086] Optionally, the kernel upgrade module 12 is further configured to: replace the current kernel file in the preview kernel with the target kernel file in the intelligent vehicle device, and restart the preview network service according to the configuration file and the dependent libraries to obtain the preview upgrade kernel.

[0087] Furthermore, the kernel upgrade module 12 is also used to: control the preview upgrade kernel to make a network connection according to a preset URL, obtain a display webpage, and obtain the loading time of the display webpage;

[0088] The preview upgrade kernel is controlled to download a preset application in the displayed webpage and the download time of the preset application is obtained;

[0089] The preview upgrade kernel is controlled to perform a webpage redirection on the displayed webpage, obtain the redirected webpage, and acquire the response time of the redirected webpage;

[0090] The network upgrade result is generated based on the loading time, the download time, and the response time.

[0091] Furthermore, the kernel upgrade module 12 is also used to: perform a weighted calculation on the loading time, the download time, and the response time to obtain the total network time;

[0092] If the total network time is less than or equal to the time threshold, the network upgrade of the intelligent vehicle device is determined to be successful.

[0093] If the total network time is greater than the time threshold, the network upgrade of the intelligent vehicle device is determined to have failed.

[0094] In this embodiment, based on the preview kernel file in the vehicle network upgrade request, the target kernel data can be automatically determined. Based on the target kernel data, a preview kernel resource package can be effectively generated. By decompressing the preview kernel file, the preview kernel in the smart vehicle device can be effectively upgraded to obtain the preview upgraded kernel, thereby achieving the network upgrade effect of the smart vehicle device without upgrading the vehicle system. This prevents incompatibility issues with other applications on the smart vehicle device and improves the user experience.

[0095] Specifically, the implementation methods of the vehicle-mounted equipment network upgrade system 100 include:

[0096] 1. Preparation Phase: The cloud server establishes a WebView kernel version library, storing different versions of WebView kernel files. The in-vehicle device has a pre-installed client program that communicates with the cloud server to send upgrade requests and receive resource packages.

[0097] 2. Upgrade Request Phase: The cloud sends an upgrade message, and the vehicle-mounted device sends an upgrade request to the cloud server through the client program, which includes the current WebView kernel version and the target upgrade version information.

[0098] 3. Resource Package Generation and Push Phase: Based on the request information, the cloud server retrieves the corresponding version of the kernel file from the version control system, re-signs it, and generates the WebView resource package. The cloud server then pushes the resource package to the in-vehicle device and sends a notification of successful push.

[0099] 4. Vehicle-mounted equipment upgrade phase: After receiving the resource package, the vehicle-mounted equipment verifies and decompresses it, replacing the old kernel file with the new one. The vehicle-mounted equipment then restarts the WebView service to make the new kernel take effect.

[0100] 5. Upgrade Verification Phase: After restarting the WebView service, the in-vehicle device verifies the success of the upgrade by loading a test webpage. If the upgrade fails, the in-vehicle device sends a failure notification to the cloud server, requesting a re-push of the resource package.

[0101] The beneficial effects of this embodiment include:

[0102] 1. Improve webpage loading speed and compatibility: By upgrading the WebView kernel, smart in-vehicle devices can load higher versions of webpages, improving webpage loading speed and compatibility.

[0103] 2. Simplified upgrade process: This invention enables remote upgrades of the WebView kernel via a cloud server, eliminating the need for users to manually download and install, thus simplifying the upgrade process.

[0104] 3. Reduced upgrade costs: The cloud server centrally manages the WebView kernel version, reducing upgrade costs for in-vehicle equipment manufacturers.
