DETAILED DESCRIPTION

[0028] The exemplary embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to enable the scope of the present application to be fully communicated to those skilled in the art.

[0029] Based on the above problems, in a first aspect of the embodiments of the present application, an OTA upgrade method is provided, which is applied to a vehicle-mounted terminal, wherein the vehicle-mounted terminal is composed of multiple modules, wherein each module contains independent configuration information, such as Figure 1 As shown, the method includes: Step S101, after the vehicle is powered on, the vehicle terminal obtains the current version information of each module respectively; Specifically, in this step, when the vehicle is powered on, the vehicle terminal will automatically start, and start to initialize each module in the system, and obtain the current version information corresponding to each module. In actual applications, the vehicle terminal can be the vehicle controller of the vehicle, or other controllers for vehicle control.

[0030] In a preferred embodiment, before the vehicle-mounted terminal respectively obtains the current version information corresponding to each module, the method further includes: The vehicle-mounted terminal obtains the current configuration files corresponding to the modules respectively; The vehicle terminal uploads the current configuration files corresponding to the modules to the cloud server, so as to download the latest configuration files corresponding to the modules from the cloud server; The vehicle terminal updates the current configuration files corresponding to the modules respectively according to the downloaded latest configuration files corresponding to the modules; After the vehicle is powered on, the vehicle terminal obtains the current version information of each module respectively, including: After the vehicle is powered on, the vehicle-mounted terminal obtains the current version information of each module respectively according to the updated configuration files corresponding to each module respectively.

[0031] Specifically, in this embodiment, before obtaining the current version information of each module, the configuration files of each module are updated first.

[0032] Specifically: after the vehicle terminal is powered on and started, the current configuration files corresponding to each module are first obtained. These configuration files contain the setting information and parameters required for the operation of each module.

[0033] Furthermore, the vehicle terminal uploads the current configuration files corresponding to each module to the cloud server, and the cloud server determines the latest configuration files corresponding to each module that are pre-stored based on the current configuration files corresponding to each module uploaded by the vehicle terminal.

[0034] Furthermore, the vehicle-mounted terminal downloads the latest configuration files corresponding to each module from the cloud server, and updates the current position files corresponding to each module according to the downloaded latest configuration files corresponding to each module.

[0035] Furthermore, after completing the update of the configuration files corresponding to the modules, the vehicle terminal will obtain the current version information of the modules based on the updated configuration files.

[0036] In a preferred embodiment, the vehicle-mounted terminal obtains the current configuration files corresponding to the modules respectively, including: The vehicle-mounted terminal initializes each module and generates status information corresponding to each module; According to the status information corresponding to each module, the current configuration files corresponding to each module are determined.

[0037] Specifically, in this embodiment, the vehicle terminal initializes each module and generates the status information corresponding to each module, that is, generates a system status snapshot of each module. Furthermore, the status information corresponding to each module is continuously scanned to obtain the current configuration file of each module.

[0038] Step S102, the vehicle terminal uploads the current version information of each module to the cloud server, so as to download the upgrade package corresponding to each module from the cloud server; Specifically, in this step, the vehicle terminal will upload the current version information of these modules to the cloud server respectively. The purpose of uploading the version information of each module is to let the cloud server know the version status of each module in the current system.

[0039] Furthermore, after receiving the version information, the cloud server will compare it with the latest version. If it is found that the version information of a module lags behind the latest version, the cloud server will generate or select the corresponding upgrade package. These upgrade packages only contain the content that needs to be updated, thereby reducing the amount of data transmission and speeding up the update process.

[0040] In a preferred embodiment, the vehicle terminal uploads the current version information of each module to the cloud server respectively, so as to download the upgrade package corresponding to each module from the cloud server, including: The vehicle terminal generates detection update requests corresponding to each module based on the current version information of each module, wherein the detection update request corresponding to each module includes the current version information of the module; The vehicle-mounted terminal sends the generated detection update requests corresponding to each of the modules to the cloud server, so as to download the upgrade packages corresponding to each of the modules from the cloud server.

[0041] Specifically, in this embodiment, after the vehicle terminal obtains the current version information of each module, it generates detection update requests corresponding to each module based on the current version information of each module, wherein the detection update request corresponding to each module will include the current version information of the module.

[0042] Furthermore, the vehicle-mounted terminal will send the generated detection and update requests corresponding to each module to the cloud server. After receiving the detection and update requests corresponding to each module, the cloud server will determine the upgrade package corresponding to each module based on the current version information in each detection and update request. The vehicle-mounted terminal will download the upgrade package corresponding to each module from the cloud server.

[0043] In a preferred embodiment, the vehicle terminal sends the generated detection update requests corresponding to each module to the cloud server to download the upgrade packages corresponding to each module from the cloud server, including: The vehicle terminal sends the detection and update requests corresponding to the modules to the cloud server, so that the cloud server parses the current version information of the modules according to the detection and update requests corresponding to the modules, and generates the differential upgrade packages corresponding to the modules according to the parsed current version information of the modules and the latest version information of the modules; The vehicle-mounted terminal downloads the differential upgrade packages corresponding to the modules from the cloud server, and uses the downloaded differential upgrade packages corresponding to the modules as the upgrade packages corresponding to the modules.

[0044] Specifically, in this embodiment, after obtaining the current version information of each module, the vehicle terminal does not directly upload the version information, but first generates a detection update request corresponding to each module. The detection update request corresponding to each module is generated separately according to the version information of each module, ensuring that the cloud server can perform version checks independently for each module.

[0045] Furthermore, after receiving the detection and update requests corresponding to each module sent by the vehicle terminal, the cloud server will first parse these requests and extract the current version information of each module. After parsing the current version information of each module, the cloud server will compare this information with the latest version information of each module stored in it. Through the comparison, it is determined whether a certain module needs to be updated. If an update is required, it is also necessary to determine which specific parts need to be updated.

[0046] Furthermore, if the comparison result shows that the current version of a module lags behind the latest version, the cloud server will generate a differential upgrade package. The core of the differential upgrade package is to only contain the parts that need to be updated, rather than the complete version information of the entire module. The purpose of this is to reduce the amount of data transmission and improve the update efficiency. For example, if only 10% of the content of a module has changed, then the differential upgrade package will only contain that 10%. In practical applications, a binary differential algorithm can be used to ensure the minimization of the differential upgrade package.

[0047] Furthermore, the vehicle-mounted terminal will download the differential upgrade packages of each module from the cloud server, and use the downloaded differential upgrade packages as upgrade packages for upgrading the corresponding modules.

[0048] Step S103 , the vehicle terminal upgrades the versions of the modules respectively according to the downloaded upgrade packages corresponding to the modules.

[0049] In this step, after the vehicle terminal downloads the upgrade packages corresponding to each module, it will process these upgrade packages as upgrade packages for each module. In actual application, the vehicle terminal decompresses and applies these upgrade packages locally to update each module to the latest status. Since the upgrade package only contains the parts that need to be upgraded, the upgrade process is relatively fast, and the delay caused by data transmission is also reduced. In addition, since the upgrade of each module is carried out independently, even if a problem occurs in a module, other modules will not be affected, thereby improving the overall stability and security of the system.

[0050] In a preferred embodiment, before the vehicle-mounted terminal downloads the upgrade packages corresponding to the modules from the cloud server, the method further includes: The vehicle terminal receives the upgrade tasks corresponding to each module sent by the cloud server; The vehicle terminal generates local upgrade tasks corresponding to the modules respectively in response to the received upgrade tasks corresponding to the modules.

[0051] Specifically, in this embodiment, after generating the upgrade packages for each module, the cloud server will generate upgrade tasks corresponding to each module according to the upgrade packages for each module, and send the upgrade tasks corresponding to each module to the vehicle terminal.

[0052] Furthermore, after receiving the upgrade tasks corresponding to each module, the vehicle terminal generates local upgrade tasks corresponding to each module in response to the received upgrade tasks corresponding to each module, and downloads the upgrade packages corresponding to each module from the cloud server based on the local upgrade tasks corresponding to each module.

[0053] In a preferred embodiment, the present application provides a Figure 2 The flowchart of the OTA upgrade method for non-pluggable modules is shown in FIG. Figure 2 As shown: When the module to be upgraded is a non-pluggable module, the vehicle terminal first updates the configuration file, and then collects the current version information of each non-pluggable module according to the configuration file, and sends a detection and update request to the cloud server with the collected current version information of each non-pluggable module, so as to obtain the upgrade package of each non-pluggable module generated by the cloud server. After the cloud server receives the detection and update request sent by the vehicle terminal, if there is a high version upgrade package, it generates a non-pluggable module independent upgrade task file on the cloud server, and sends the task information to the vehicle terminal, and then the vehicle terminal parses the task sent by the cloud, and then the vehicle terminal generates a local non-pluggable module independent upgrade task according to the parsed task information, so as to download and deploy the upgrade package. At this time, the vehicle terminal distinguishes which tasks need to be manually triggered and which tasks can be executed automatically according to whether the single independent upgrade task in the task information supports automatic upgrade. For tasks that do not support automatic upgrade, the user is prompted through a pop-up window when the upgrade conditions are met. After the user confirms the installation, the installation process is executed, and the installation result is finally generated, and the installation result is uploaded to the cloud server.

[0054] In a second aspect of the present application, an OTA upgrade method is provided, which is applied to a cloud server, such as Figure 3 As shown, the method includes: Step S201, the cloud server receives the current version information of each module uploaded by the vehicle terminal; In step S202, the cloud server generates an upgrade package corresponding to each module according to the received current version information of each module.

[0055] Specifically, after the cloud server receives the current version information of each module uploaded by the vehicle terminal, the cloud server parses the received current version information of each module and generates an upgrade package corresponding to each module according to the parsed result.

[0056] In a preferred embodiment, the cloud server generates an upgrade package corresponding to each module according to the received current version information of each module, including: The cloud server determines the pre-stored latest version information of each module according to the received current version information of each module; The cloud server determines the content to be upgraded corresponding to each module according to the current version information of each module and the latest version information of each module; The cloud server generates an upgrade package corresponding to each module based on the content to be upgraded corresponding to each module.

[0057] Specifically, the cloud server determines the latest version information of each module pre-stored therein by scanning according to the received current version information of each module; Furthermore, based on the current version information of each module received and the latest version information of each module pre-stored, the current version information of each module is compared with the latest version information of the module pre-stored to determine the content to be upgraded for each module, and based on the upgraded content of each module, a differential upgrade package corresponding to each module is generated, wherein the differential upgrade package of each module will be used as the upgrade package for upgrading the module.

[0058] In a preferred embodiment, the cloud server receives the current configuration files corresponding to each module uploaded by the vehicle terminal; The cloud server determines the pre-stored latest configuration files corresponding to each of the modules according to the received current configuration files corresponding to each of the modules.

[0059] Specifically, in this embodiment, after the cloud server receives the current configuration files corresponding to each module uploaded by the vehicle-mounted terminal, the cloud server determines the pre-stored latest configuration files corresponding to each module based on the received current configuration files corresponding to each module, downloads the latest configuration files corresponding to each module from the cloud server through the vehicle-mounted terminal, and updates the current configuration files corresponding to each module based on the downloaded latest configuration files corresponding to each module.

[0060] In a preferred embodiment, the present application provides a Figure 4 The flowchart of the OTA upgrade method for the pluggable module is shown in FIG. Figure 4 As shown: The vehicle terminal first updates the configuration file, then sends a request to the device configuration module to collect the current version information of each pluggable module, and collects the current version information of each pluggable module. The device configuration module sends the collected current version information of each pluggable module to the vehicle terminal, and the vehicle terminal then uses the collected current version information of each module to send a detection and update request to the cloud server to obtain the upgrade package information of the cloud server. After the cloud server receives the detection and update request sent by the vehicle terminal, if there is a high-version upgrade package, it generates a pluggable module independent upgrade task file in the cloud, and sends the task information to the vehicle terminal, and then the vehicle terminal parses the task sent by the cloud server, and then the vehicle terminal generates a local pluggable module independent upgrade task based on the parsed task information, so as to download and deploy the upgrade package. The vehicle terminal then sends the pluggable module upgrade task to the device management module. After receiving the task file, the device management module displays which pluggable modules can be upgraded on the interface, and the user triggers the installation. The vehicle terminal then executes the installation process, returns the installation progress during the installation process, and finally returns the installation result. It will also synchronize the installation progress and installation results to the device management module in real time, and finally display the installation results on the device management module.

[0061] In a preferred embodiment, before the vehicle-mounted terminal downloads the upgrade packages of each module from the cloud server, the cloud server encrypts each upgrade package to prevent the data from being stolen or tampered with during transmission.

[0062] After the upgrade package is downloaded, the vehicle terminal will verify the digital signature. The digital signature is an encrypted hash value of the data, which is used to verify the integrity and authenticity of the data. The vehicle terminal uses the pre-stored public key to decrypt the digital signature and compare it with the hash value of the upgrade package. If it matches, it means that the upgrade package has not been tampered with and the data is complete and authentic. During the upgrade process, the vehicle terminal will back up the data regularly. This means that before starting the actual upgrade operation, the vehicle terminal will save the current configuration file and the current version information. If there is a problem during the upgrade process, the vehicle terminal can use the backup data for recovery to ensure that it can be restored to a stable state. In actual applications, the SSL / TLS protocol is used to ensure the security of data transmission. After the download is complete, the integrity of the update package is verified by the SHA-256 digital signature.

[0063] In a preferred embodiment, the vehicle terminal uses an intelligent scheduling algorithm to optimize the download and installation order of the upgrade package to minimize the system load of the vehicle during driving. Specifically, the distribution and installation of the upgrade package will be dynamically adjusted according to the vehicle's usage status (such as driving, parking, etc.). When the vehicle is parked, the download and installation of the upgrade package will be prioritized, while the update operation will be reduced or suspended during the vehicle's driving to avoid adverse effects on the vehicle's operation. This intelligent scheduling mechanism ensures that the impact of the update process on vehicle performance is minimized, improving the system's operating efficiency and user experience.

[0064] In a preferred embodiment, the vehicle terminal monitors various indicators in real time during the version upgrade of each module to ensure the smooth progress of the upgrade. After the upgrade is completed, a detailed feedback report is generated to record the upgrade process and results, and uploaded to the cloud server for the administrator to view. In actual application, the vehicle terminal has a built-in monitoring module to record various parameters during the upgrade process (such as download speed, update progress, system load, etc.) in real time, and generates a log report after the upgrade is completed, recording each step of the operation in detail, which is convenient for subsequent analysis and troubleshooting.

[0065] The present application obtains the current version information of each module through the vehicle-mounted terminal, and based on the obtained current version information, obtains the upgrade package from the cloud server to upgrade each module separately. The present application actively obtains the upgrade package of each module from the cloud server through the vehicle-mounted terminal, and upgrades each module separately based on the upgrade package obtained from the cloud server, so that the upgrade of each module is relatively independent and will not be affected by each other, thereby improving the stability and security of the system upgrade.
