[0026] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0027] Figure 1 It is a schematic flowchart of the vehicle offline upgrade method provided by the present invention, characterized by including: Step 110, the diagnostic device sends the vehicle software version information of the target vehicle to the software platform; wherein, the vehicle software version information is used to instruct the software platform to send software upgrade information to the diagnostic device when it detects that the latest vehicle software version information of the target vehicle is inconsistent with the vehicle software version information. In the present invention, the diagnostic device is a special tool, usually used in the process of automobile maintenance and repair, for reading information such as vehicle fault codes, real-time data, and freeze frame data. It communicates with the vehicle's electronic control unit (ECU) through the vehicle's on-board diagnostics (OBD) interface. The diagnostic device can be a handheld scanning tool or a more complex computer system, which can identify and solve potential vehicle problems, as well as perform tasks such as software updates and resets.

[0028] In the present invention, the target vehicle refers to a specific vehicle that needs to be diagnosed, repaired, or have its software updated. In the automotive industry, each vehicle has its own electronic system and software, which may need to be updated regularly to fix vulnerabilities, improve performance, or add new features. The target vehicle is the focus of all relevant operations and update processes, ensuring that its software and hardware systems are in the best state.

[0029] In the present invention, the software platform is a centralized system for managing, storing, and distributing vehicle software updates. It usually includes a database containing software update information for different vehicle models and versions. The software platform is responsible for receiving query requests from the diagnostic device, comparing the current vehicle software version with the latest version, and providing updates when necessary. In addition, the software platform may also provide a user interface that allows technicians to easily manage and execute software update tasks. The software platform ensures the security, compliance, and effectiveness of software updates and is a key component of vehicle software life cycle management.

[0030] The diagnostic device sends the software version information of the target vehicle to the software platform to ensure that the software platform can timely understand the current software status of the vehicle.

[0031] The software platform intelligently detects whether there is a version update by comparing the sent vehicle software version information with the latest version information cached in the platform. When a version inconsistency is detected, the software platform can timely send software upgrade information to the diagnostic device to ensure that the vehicle can timely receive the latest software update. By sending upgrade information only when the version information is inconsistent, unnecessary communication is reduced, and the efficiency of the system is improved.

[0032] Step 120, when the diagnostic device receives the software upgrade information, download the latest vehicle software version of the target vehicle according to the software upgrade information. After receiving the software upgrade information sent by the software platform, the diagnostic device will perform the next steps according to this information to ensure that the vehicle software can be updated to the latest version in a timely manner.

[0033] The diagnostic device automatically downloads the latest vehicle software version of the target vehicle according to the instructions in the software upgrade information, reducing manual intervention and improving the efficiency and accuracy of the upgrade process.

[0034] Through the precise upgrade information provided by the software platform, the diagnostic device can download a software version that is fully compatible with the target vehicle, avoiding problems caused by version mismatch.

[0035] In the invention, during the download process, an encrypted transmission protocol (such as TLS / SSL) is usually adopted to protect the security of data during transmission and prevent the data from being intercepted or tampered with.

[0036] Step 130, when the latest vehicle software version of the target vehicle downloaded passes the verification, the diagnostic device installs the latest vehicle software version for the target vehicle.

[0037] In the present invention, before installation, the diagnostic device verifies the integrity and authenticity of the downloaded vehicle software version. This is usually done by comparing the hash value of the downloaded file with the hash value provided by the software platform to ensure that the software package has not been tampered with or damaged during transmission.

[0038] The verification process also includes checking whether the software package meets the security standards and compliance requirements to ensure that the installed software will not pose potential risks to the vehicle system. Once the verification passes, the diagnostic device will automatically start installing the latest vehicle software version. This process usually includes transmitting the software package to the vehicle's ECU and executing the necessary installation commands.

[0039] In the present invention, in the case where the diagnostic device receives the software upgrade information, the latest vehicle software version of the target vehicle is downloaded according to the software upgrade information, realizing precise vehicle software version information exchange, intelligent software upgrade information push, secure package download and verification, and reliable software installation process, achieving efficient and secure upgrade of vehicle software. This process not only ensures that the vehicle system always runs in the latest state, improving vehicle performance and safety, but also reduces maintenance costs and customer complaints by reducing human operation errors and improving operation convenience, thereby enhancing vehicle reliability and user satisfaction.

[0040] Optionally, the software upgrade information includes at least one of the following: download address information of the latest vehicle software version, software installation requirement information, software hash value information.

[0041] Before the step of the diagnostic device installing the latest vehicle software version for the target vehicle when the latest vehicle software version information of the downloaded target vehicle passes the verification, the method further includes: Performing a hash calculation on the latest vehicle software version through a hash algorithm to obtain a first hash value; When the first hash value is consistent with the software hash value information, determining that the content integrity of the latest vehicle software version passes the verification; When the content integrity of the latest vehicle software version passes the verification and the compliance check passes, determining that the latest vehicle software version information of the target vehicle passes the verification.

[0042] In the present invention, a hash calculation is performed on the latest vehicle software version through a hash algorithm to obtain a first hash value. This step is to verify the integrity of the software package and ensure that the software package has not been tampered with during transmission or storage.

[0043] Comparing the calculated first hash value with the software hash value information provided by the software platform. If the two are consistent, it indicates that the content integrity of the software package has passed the verification, ensuring that the software package has not been illegally tampered with during transmission.

[0044] On the basis that the content integrity passes the verification, a compliance check is also required. This step ensures that the software version complies with relevant regulations and safety standards. For example, the software upgrade management system required by the UNECE R156 regulation includes verification before upgrade, monitoring during upgrade, and verification after upgrade, etc.

[0045] Only when the content integrity of the latest vehicle software version passes the verification and the compliance check passes, can it be determined that the latest vehicle software version information of the target vehicle passes the verification. This is the last safety check before installation, ensuring the security and compliance of the software.

[0046] In the present invention, a comprehensive security verification process aims to protect the authenticity and integrity of software upgrades, prevent invalid upgrades, and ensure the security and compliance of the software upgrade process. Through this process, data damage during the software upgrade process can be reasonably prevented, and unauthorized access and tampering can be prevented, thereby ensuring the safe upgrade of vehicle software.

[0047] Optionally, the diagnostic device installing the latest vehicle software version for the target vehicle includes: The diagnostic device obtains the current vehicle state information of the target vehicle; When the current vehicle state information meets the software installation requirement information, installing the latest vehicle software version for the target vehicle according to the installation instruction.

[0048] In the present invention, the diagnostic device first needs to obtain the current status information of the target vehicle. This includes but is not limited to key information such as the vehicle's battery voltage, engine status, whether the vehicle is stationary, and whether the doors are closed.

[0049] The software installation requirement information refers to the conditions that must be met before installing a new software version. For example, the vehicle must be stationary, the battery voltage must be within a specific range, and certain vehicle systems must be turned off. The diagnostic device compares the obtained current vehicle status information with the software installation requirement information to determine whether the installation conditions are met.

[0050] If the current vehicle status information meets the software installation requirements, the diagnostic device will continue with the installation process. If the conditions are not met, the diagnostic device may prompt the user to take corresponding measures, such as parking, charging, or turning off certain systems.

[0051] After confirming that the conditions are met, the diagnostic device starts installing the latest vehicle software version for the vehicle according to the preset installation instructions. This may include operations such as transferring the software package to the vehicle's ECU, performing necessary file replacements, and configuration updates.

[0052] In the present invention, the diagnostic device ensures the security and effectiveness of software installation, and also improves the user experience because users can be confident that their vehicle software is up-to-date and the installation process has been strictly verified.

[0053] Optionally, after the step of calculating the hash value of the latest vehicle software version through the hash algorithm to obtain the first hash value, the method further includes: In the case where the first hash value is inconsistent with the software hash value information, it is determined that the content integrity of the latest vehicle software version fails to pass the verification, and a file error warning message is generated; Delete the latest vehicle software version and re-download the latest vehicle software version of the target vehicle.

[0054] In the present invention, when the first hash value is inconsistent with the software hash value information, the system determines that the content integrity of the latest vehicle software version fails to pass the verification. This means that during the download process, the file may have been corrupted or tampered with.

[0055] At this time, a file error warning message is generated to notify the user or system administrator of the hash value mismatch problem. This warning can be a log record, a message prompt on the user interface, or an automatically sent error report.

[0056] In the present invention, after deleting the damaged file, the system will restart the download process and download the latest vehicle software version of the target vehicle from the software platform again. This step ensures that the user can obtain a complete and unmodified software version.

[0057] After the re-download is completed, the system will use the hash algorithm to calculate the hash of the newly downloaded software version again and compare it with the hash value information provided by the software platform to verify the integrity of the newly downloaded file.

[0058] Figure 2 The overall flowchart of the vehicle offline upgrade provided by the present invention is as Figure 2 shown and includes: The maintenance personnel accurately read the actual vehicle version number through the diagnostic tablet and conveniently report the vehicle series information to the unified software management platform; After receiving the uploaded vehicle series and version number, the software management platform immediately starts the intelligent matching mechanism, automatically retrieves and generates the corresponding upgrade task information, including the detailed ECU name, the status satisfied by the vehicle, the encryption key, and the program package download link. This information will be seamlessly connected to the diagnostic tablet to provide the maintenance personnel with a one-stop, efficient and convenient upgrade service experience; With a simple click on the diagnostic platform, the download process of the upgrade package can be started. After the download is completed, the system will automatically perform a strict integrity check of the program package, use an advanced hash algorithm to ensure that the file content is intact, and at the same time perform a compliance check to double-guarantee the authenticity and security of the program package, ensure the smooth progress of the upgrade process, and ensure that the program package is pure and not tampered with; After clicking the "Install" button, the system will immediately evaluate and display all the necessary conditions currently satisfied by the vehicle for flashing. After confirming that the vehicle status meets the requirements, you only need to simply confirm to start the accurate flashing process of the vehicle parts. The aim is to ensure the safety and effectiveness of the flashing operation.

[0059] In the present invention, during the program download process, the TLS protocol is adopted to ensure the security of information transmission and effectively prevent eavesdropping and attacks that may occur during the data transmission process. In addition, this method also has multiple advantages such as ensuring the integrity of the program package, preventing tampering, and being simple and efficient in operation.
