[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0043] Embodiment 1

[0044] See also Figure 1 , is a flow chart of a vehicle-mounted device network upgrade method provided by a first embodiment of the present invention. The vehicle-mounted device network upgrade method can be applied to any device or system. The vehicle-mounted device network upgrade method comprises the steps of:

[0045] Step S10, obtaining a vehicle network upgrade request sent by the intelligent vehicle device, and determining target kernel data according to the preview kernel file in the vehicle network upgrade request;

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

[0047] Optionally, determining the target kernel data according to the preview kernel file in the vehicle network upgrade request includes:

[0048] Obtaining the current kernel version and the target upgrade version in the vehicle network upgrade request, and combining the current kernel version and the target kernel upgrade version to obtain kernel combination information; wherein, by combining the current kernel version and the target kernel upgrade version, the subsequent matching operation between the 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 target kernel data, configuration files and dependent libraries, and the target kernel file, the configuration files and the dependent libraries are combined to obtain the target kernel data; wherein the preview kernel version library stores the correspondence between different kernel combination information and the corresponding target kernel data, configuration files and dependent libraries.

[0050] Furthermore, before obtaining the vehicle network upgrade request sent by the intelligent vehicle device, it also includes:

[0051] Acquire an environment image of the intelligent vehicle-mounted device corresponding to the user's vehicle, and perform vehicle recognition on the environment image to obtain a recognized vehicle; wherein, an image is captured in the environment where the intelligent vehicle-mounted device is currently located to obtain an environment image, and vehicle recognition is performed on the vehicles in the environment image to obtain the model of each recognized vehicle;

[0052] Matching the user vehicle with the identified vehicle, and determining an associated vehicle according to the vehicle matching result; wherein the model of the user vehicle is matched with the model of the identified vehicle, and based on the vehicle matching result, determining the identified vehicle of the same model as the user vehicle as the associated vehicle;

[0053] Sending kernel version request information to the associated vehicle, and receiving a kernel version response to the kernel version request information; wherein the kernel version information of the associated vehicle is obtained by sending the kernel version request information to the associated vehicle;

[0054] Matching the kernel version in the kernel version response with the current kernel version of the smart vehicle-mounted device; wherein, 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 smart vehicle-mounted device, and if the version of the preview kernel in the associated vehicle is higher than the kernel version of the smart vehicle-mounted device, it is determined that the kernel version in the kernel version response successfully matches the current kernel version;

[0055] If the kernel version in the kernel version response successfully matches the current kernel version, controlling the vehicle network upgrade request sent by the intelligent vehicle device;

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

[0057] Step S20, generating a preview kernel resource package according to the target kernel data, and sending the preview kernel resource package to the intelligent vehicle-mounted device for decompression to obtain a preview kernel decompressed file;

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

[0059] Optionally, generating a preview kernel resource package according to the target kernel data includes:

[0060] The signature information of the cloud server and the preview kernel version library is obtained to obtain the server signature and the version library signature, and the target kernel data is re-signed according to the server signature and the version library signature to obtain the preview kernel resource package; wherein, re-signing the target kernel data by the server signature and the version library signature facilitates the decompression and verification of the preview kernel resource package by the smart vehicle-mounted device. Specifically, the cloud server pushes the generated preview kernel resource package to the smart vehicle-mounted device requesting the upgrade, and after receiving the resource package, the vehicle-mounted device verifies and decompresses it to obtain the preview kernel decompressed file.

[0061] Step S30, performing a version upgrade on the preview kernel in the smart vehicle-mounted device according to the preview kernel decompression file to obtain a preview upgrade kernel, and performing a network test on the preview upgrade kernel to obtain a network upgrade result of the smart vehicle-mounted device;

[0062] Among them, determine whether the preview is compatible. If the preview kernel decompression file can be directly installed, if the installation is successful, it means that the preview version can be directly upgraded. If the installation fails, you need to delete the preview file (system / app / webview) before installing it. In this step, after the smart car device completes the kernel replacement, it restarts the preview service to make the new kernel effective. After restarting, perform a network test on the preview upgrade kernel to detect whether the network upgrade of the smart car device is successful. If the network upgrade is successful, the smart car device can use the new version of the preview kernel to load the web page, improving the web page loading speed and compatibility.

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

[0064] Further, a network test is performed on the preview upgrade kernel to obtain a network upgrade result of the intelligent vehicle-mounted device, including:

[0065] According to the preset website, the preview upgrade kernel is controlled to connect to the network, a displayed web page is obtained, and the loading time of the displayed web page is obtained; wherein the preset website can be set according to the demand, and by controlling the preview upgrade kernel to connect to the network, the network loading speed of the preview upgrade kernel can be effectively tested;

[0066] Controlling the preview upgrade kernel to download the preset application in the display webpage, and obtaining the download time of the preset application; wherein the preset application can be set according to demand, and by downloading the preset application in the display webpage, the network download speed of the preview upgrade kernel can be effectively tested;

[0067] Control the preview upgrade kernel to perform a web page jump in the displayed web page, obtain a jump web page, and obtain the response time of the jump web page; wherein, by performing a web page jump in the displayed web page, the network response speed of the preview upgrade kernel can be effectively tested;

[0068] The network upgrade result is generated according to the loading time, the downloading time and the response time.

[0069] Furthermore, generating the network upgrade result according to the loading time, the downloading time and the response time includes:

[0070] Performing weighted calculation on the loading time, the downloading time and the response time to obtain a total network time; wherein the weighted coefficients of the loading time, the downloading time and the response time in the weighted calculation process can be set according to requirements;

[0071] If the total network time is less than or equal to the time threshold, it is determined that the network upgrade of the smart vehicle device is successful; if the total network time is greater than the time threshold, it is determined that the network upgrade of the smart vehicle device has failed; wherein, the time threshold can be set according to needs.

[0072] In this embodiment, based on the preview kernel file in the vehicle network upgrade request, the target kernel data can be automatically determined, and the preview kernel resource package can be effectively generated based on the target kernel data. The preview kernel decompression file can be effectively upgraded to the preview kernel in the smart vehicle device to obtain the preview upgraded kernel, so as to achieve the network upgrade effect of the smart vehicle device. There is no need to upgrade the vehicle system, which prevents incompatibility of other applications on the smart vehicle device and improves the user experience.

[0088] Controlling the preview upgrade kernel to download the preset application in the display webpage, and obtaining the download time of the preset application;

[0089] Controlling the preview upgrade kernel to perform a web page jump in the displayed web page, obtaining a jump web page, and acquiring a response time of the jump web page;

[0090] The network upgrade result is generated according to the loading time, the downloading time and the response time.

[0092] If the total network duration is less than or equal to the duration threshold, it is determined that the network upgrade of the intelligent vehicle-mounted device is successful;

[0093] If the total network duration is greater than the duration threshold, it is determined that the network upgrade of the intelligent vehicle-mounted device has failed.
