[0060] With the rapid development of Internet of Vehicles technology, cars have entered an era of intelligence and networking. In-vehicle Internet technology has become a trend in the development of automotive technology. The update and optimization of vehicle controller software and in-vehicle application software, as well as the update of functions, can effectively improve the driving experience and enhance the satisfaction of car owners.

[0061] Based on the technology of Internet of Vehicles, remote upgrading of controller software through OTA push is a development trend of intelligent networked vehicles. Software has become the fastest iterating and most easily personalized part of the car. At the same time, the maintenance of software failures and software updates based on user needs cannot meet user needs only through offline. Therefore, OTA can realize the continuous upgrading of the entire vehicle system, allowing users to obtain a better driving experience.

[0062] As more and more domestically produced cars are exported and sold overseas, they are bound to face the problem of cross-border upgrades of OTA upgrade packages. However, at present, cross-border upgrades of automobile OTA upgrade packages are mainly manually uploaded to the OTA platform by operation and maintenance personnel, which leads to low upgrade efficiency.

[0063] Based on this, an embodiment of the present application provides a method for cross-border transmission of automobile OTA upgrade packages, aiming to propose an effective and feasible method for cross-border transmission of automobile OTA upgrade packages, which can improve the efficiency of cross-border upgrades of automobile OTA.

[0064] Reference Figure 1 As shown, Figure 1 A first flow chart of a method for cross-border transmission of an automobile OTA upgrade package executed by an overseas OTA platform is shown, which includes at least steps 110 to 130, which are described in detail as follows:

[0065] Step 110, receiving upgrade package information corresponding to the part to be upgraded sent by the domestic vehicle information management platform, and updating the stored original upgrade package information, wherein the upgrade package information includes the upgrade package name and the upgrade package storage path, wherein the upgrade package file corresponding to the part to be upgraded is uploaded and stored in a foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded;

[0066] Step 120, sending the upgrade package name, the upgrade package storage path and a download link request to the overseas TSP, so that the overseas TSP requests the foreign storage bucket to generate a download link according to the upgrade package name and the upgrade package storage path;

[0067] Step 130: receiving a download link returned by the overseas TSP, and downloading a corresponding upgrade package file based on the download link.

[0068] In the embodiment of the present application, the domestic vehicle information management platform obtains the upgrade package information corresponding to the part to be upgraded, wherein the upgrade package related information includes the hardware part number, the software part number and the software version number, and the upgrade package related information is used to determine the unique upgrade package file corresponding to the part to be upgraded. At the same time, through the interaction between the domestic vehicle information management platform and the domestic MAS platform, the upgrade package file corresponding to the part to be upgraded can be uploaded and stored in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded. Therefore, when it is necessary to upgrade the part to be upgraded, the domestic vehicle information management platform can send the upgrade package information corresponding to the part to be upgraded to the overseas OTA platform, wherein the upgrade package information includes the upgrade package related information, the upgrade package name and the upgrade package storage path. After receiving the upgrade package information, the overseas OTA platform can send the upgrade package name, the upgrade package storage path and the download link request to the overseas TSP, so that the overseas TSP can generate the download link of the upgrade package corresponding to the part to be upgraded according to the upgrade package name and the upgrade package storage path. After obtaining the download link, the overseas TSP returns to the overseas OTA platform, so that the overseas OTA platform can download the corresponding upgrade package file based on the returned download link. This completes the entire process of cross-border transmission of the upgrade package, and the entire process is performed purely online without human intervention, which can improve the efficiency of cross-border upgrades of OTA upgrade packages. The upgrade package uses a third-party cloud storage service (domestic storage bucket and foreign storage bucket) for cross-border transmission, and uses rule configuration to specify which vehicle parts need to be transmitted to which domestic storage buckets in which countries and regions, and supports transmission in multiple countries and regions, which can reduce dedicated line investment. At the same time, during the transmission process, the upgrade package is encrypted and signed throughout the entire process through PKI, which can ensure the security of the upgrade link and the integrity of the upgrade package.

[0069] Reference Figure 2 As shown, Figure 2 A second flow chart of a method for cross-border transmission of an automobile OTA upgrade package executed by an overseas OTA platform is shown, which includes at least steps 210 to 230, which are described in detail as follows:

[0070] Step 210, receiving the upgrade package information corresponding to the part to be upgraded sent by the domestic vehicle information management platform, and updating the stored original upgrade package information, wherein the upgrade package information includes the upgrade package name and the upgrade package storage path, wherein the upgrade package file corresponding to the part to be upgraded is uploaded and stored in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded;

[0071] Step 220, sending the upgrade package name, upgrade package storage path and download link request to the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded;

[0072] Step 230, receiving the download link returned by the foreign storage bucket, and downloading the corresponding upgrade package file based on the download link.

[0073] In the embodiment of the present application, the domestic vehicle information management platform obtains the upgrade package information corresponding to the part to be upgraded, wherein the upgrade package related information includes the hardware part number, the software part number and the software version number, and the upgrade package related information is used to determine the unique upgrade package file corresponding to the part to be upgraded. At the same time, through the interaction between the domestic vehicle information management platform and the domestic MAS platform, the upgrade package file corresponding to the part to be upgraded can be uploaded and stored in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded. Therefore, when it is necessary to upgrade the part to be upgraded, the domestic vehicle information management platform can send the upgrade package information corresponding to the part to be upgraded to the overseas OTA platform, wherein the upgrade package information includes the upgrade package related information, the upgrade package name and the upgrade package storage path. After the overseas OTA platform receives the upgrade package information, it can directly send the upgrade package name, the upgrade package storage path and the download link request to the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded, so that the foreign storage bucket can return the download link of the upgrade package corresponding to the part to be upgraded to the overseas OTA platform according to the upgrade package name and the upgrade package storage path. The overseas OTA platform can download the corresponding upgrade package file based on the returned download link. This completes the entire process of cross-border transmission of the upgrade package, and during this process, everything is executed purely online without the need for human intervention, which can improve the efficiency of cross-border upgrades of OTA upgrade packages.

[0074] It should be noted that, in some embodiments, before receiving the upgrade package information sent by the domestic vehicle information management platform, the overseas OTA platform may also send a cross-border transmission request for the upgrade package and upgrade package related information to the domestic vehicle information management platform. That is, the overseas OTA platform initiates a cross-border transmission request for the upgrade package to the domestic vehicle information management platform, and brings in the upgrade package related information, such as the hardware part number, software part number, and software version number, to determine the unique upgrade package file corresponding to the part to be upgraded. After receiving the cross-border request for the upgrade package, the domestic vehicle information management platform uploads the upgrade package file corresponding to the part to be upgraded and stores it in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded through the interaction between the domestic vehicle information management platform and the domestic MAS platform.

[0075] Reference Figure 3 , Figure 3 The flowchart shows the steps performed by the overseas OTA platform after downloading the corresponding upgrade package file based on the download link, which at least includes steps 310 to 320, which are described in detail as follows:

[0076] Step 310: Use the public key to verify the signature of the upgrade package file, and use the encryption algorithm to decrypt the upgrade package;

[0077] Step 320, after the signature verification and decryption are passed, the upgrade package file is re-signed and encrypted and uploaded to the storage path specified by the foreign storage bucket in the corresponding region, and the overseas download link of the upgrade package file is obtained.

[0078] In the embodiment of the present application, after downloading the upgrade package file corresponding to the part to be upgraded, the overseas OTA platform can use the public key to verify the signature of the upgrade package file, and use the encryption algorithm to decrypt the upgrade package file, and compare whether the hash value contained in the upgrade package file is consistent with the decrypted hash value, so as to further ensure that the upgrade package file has not been tampered with. After the overseas OTA platform verifies and decrypts the upgrade package, it can further use the overseas PI signature service to re-sign and encrypt the upgrade package file, and upload it to the folder specified by the overseas storage bucket of the export country and region corresponding to the associated model of the part to be upgraded (with CDN), and obtain the overseas download link of the upgrade package file.

[0079] In some embodiments, after the overseas OTA platform re-signs and encrypts the upgrade package file and uploads it to the storage path specified by the foreign storage bucket in the corresponding region, and obtains the overseas download link of the upgrade package file, it will send the upgrade task of the parts to be upgraded to the overseas vehicle. When the overseas vehicle detects the upgrade task and meets the upgrade conditions, it will upload the upgrade request to the overseas OTA platform. When the overseas OTA receives the upgrade request uploaded by the overseas vehicle, it will send the overseas download link of the upgrade package file corresponding to the parts to be upgraded to the overseas vehicle, so that the overseas vehicle can download the upgrade package file corresponding to the parts to be upgraded based on the overseas download link and then upgrade. Specifically, when the overseas OTA receives the upgrade request uploaded by the overseas vehicle, the overseas OTA platform synchronizes the download link and hash value of the upgrade package file corresponding to the parts to be upgraded to the overseas vehicle side, and the vehicle side uses the download link to download the upgrade package file, and uses the PKI certificate preset on the vehicle side to verify the signature of the downloaded upgrade package file; and after decrypting it using the decryption algorithm, compare the decrypted hash value with the hash value synchronized to the vehicle side by the overseas OTA platform to see if they are consistent. If they are consistent, the upgrade process will continue to be completed. This ensures the integrity and security of the upgrade package throughout the entire upgrade chain.

[0080] Specifically, after the overseas OTA platform verifies and decrypts the upgrade package, it can calculate the summary of the upgrade package file, that is, perform hash calculation on the upgrade package to generate the hash value of the file. The purpose is to verify the integrity of the upgrade package. After the vehicle downloads the upgrade package, it will also perform hash calculation on the upgrade package file, and then compare the hash value of the vehicle with the hash value of the overseas OTA platform cloud. If they are the same, the upgrade package is considered complete. Then, with the summary of the upgrade package file and the OTA upgrade content as parameters, request a signature from the security service platform. If the signature fails, the corresponding error message is returned and the process ends; if the signature succeeds, the signed value and the corresponding signature certificate chain are returned. The OTA service integrates the signature result and the signature certificate chain into the upgrade package, and the OTA service generates the upgrade package encryption key EK and saves EK (when the vehicle requests the upgrade package information, the EK will be sent to the vehicle); the OTA service uses the key EK to encrypt the upgrade package; after encryption, the OTA service uploads the encrypted upgrade package to the CDN.

[0081] The vehicle OTA client UC Master uses the IVI (In-Vehicle Infotainment) device certificate to establish an HTTPS two-way authentication channel with the OTA service based on the IVI device certificate; the OTA client UC Master requests the new version information from the OTA service, and the OTA service returns the new version download address and the corresponding encryption key EK. UC Master downloads the new version of the upgrade package, decrypts it with the encryption key EK, and parses the upgrade package, certificate chain, and encrypted summary. UCMaster takes out the certificate chain from the decrypted file and uses the vehicle-side PKI SDK to verify the legitimacy of the certificate chain; if it is illegal, an error is returned and the process ends; if it is legal, the signature (generated after the summary is encrypted) is verified using the certificate (that is, the encrypted summary is decrypted using the certificate public key). If the verification fails, an error is returned; if the verification passes, the upgrade package summary calculated by the server will be decrypted, and UC Master will perform hash calculation on the downloaded upgrade package source file, and then compare it with the decrypted summary. If they are the same, the upgrade package is considered legal and the installation operation can be performed later; otherwise, failure is returned.

[0082] Reference Figure 4 As shown, Figure 4 A first flow chart of a method for cross-border transmission of an automobile OTA upgrade package executed by a domestic vehicle information management platform is shown, which includes at least steps 410 to 420, which are described in detail as follows:

[0083] Step 410, by interacting with the domestic MAS platform, the upgrade package file corresponding to the part to be upgraded is uploaded and stored in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded;

[0084] Step 420, sends the upgrade package information of the parts to be upgraded to the overseas OTA, so that the overseas OTA requests a download link from the overseas TSP or foreign storage bucket based on the upgrade package information of the parts to be upgraded, so as to download and upgrade the corresponding upgrade package file based on the returned download link, wherein the upgrade package information includes the upgrade package name and the upgrade package storage path.

[0085] In an embodiment of the present application, the domestic vehicle information management platform can upload and store the upgrade package file corresponding to the part to be upgraded to the foreign storage bucket of the export country and region corresponding to the associated vehicle model of the part to be upgraded by interacting with the domestic MAS platform. Therefore, when the part to be upgraded needs to be upgraded, the domestic vehicle information management platform can send the upgrade package information corresponding to the part to be upgraded to the overseas OTA platform, wherein the upgrade package information includes upgrade package related information, upgrade package name and upgrade package storage path. After the overseas OTA platform receives the upgrade package information, it can send the upgrade package name, upgrade package storage path and download link request to the overseas TSP or to the foreign storage bucket of the export country and region corresponding to the associated vehicle model of the part to be upgraded to obtain the download link of the upgrade package corresponding to the part to be upgraded. The overseas OTA platform can download the corresponding upgrade package file based on the returned download link. The entire process of cross-border transmission of the upgrade package is thus completed, and in this process, all pure online execution is performed without human participation, which can improve the efficiency of cross-border upgrade of OTA upgrade packages.

[0086] It should be noted that, in some embodiments, an overseas OTA platform may initiate a cross-border transmission request for an upgrade package to a domestic vehicle information management platform, and bring in relevant information about the upgrade package, such as hardware part number, software part number, and software version number, to determine the unique upgrade package file corresponding to the part to be upgraded. After receiving the cross-border request for the upgrade package, the domestic vehicle information management platform, through the interaction between the domestic vehicle information management platform and the domestic MAS platform, uploads the upgrade package file corresponding to the part to be upgraded and stores it in a foreign storage bucket corresponding to the export country or region of the associated vehicle model of the part to be upgraded.

[0087] Reference Figure 5 As shown, Figure 5 The flowchart shows the steps executed by the domestic vehicle information management platform to upload and store the upgrade package file corresponding to the part to be upgraded to the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded by interacting with the domestic MAS platform, which at least includes steps 510 to 530, which are described in detail as follows:

[0088] Step 510, sending the upgrade package related information of the part to be upgraded to the domestic MAS platform to query the upgrade package name and download link corresponding to the upgrade package;

[0089] Step 520, receiving the upgrade package name and download link returned by the domestic MAS platform, and downloading the upgrade package file with the upgrade package name based on the download link;

[0090] Step 530, query the associated vehicle model of the parts to be upgraded based on the upgrade package related information, and upload the upgrade package file to the domestic storage bucket and storage path of the export country and region corresponding to the associated vehicle model, so that the corresponding domestic storage bucket stores the upgrade package file and then synchronizes the upgrade package file to the corresponding foreign storage bucket.

[0091] In the embodiment of the present application, the domestic vehicle information management platform first sends the upgrade package related information of the parts to be upgraded, such as the hardware part number, software part number, and software version number, to the domestic MAS platform to query the upgrade package name and download link of the upgrade package. The domestic MAS platform returns the download address and upgrade package name of the encrypted upgrade package file to the domestic vehicle information management platform, so that the domestic vehicle information management platform can download the upgrade package file based on the returned download link. The domestic vehicle information management platform also queries the associated vehicle model of the parts to be upgraded based on the upgrade package related information, and uploads the upgrade package file to the domestic storage bucket and storage path of the export country and region corresponding to the associated vehicle model, so that the corresponding domestic storage bucket stores the upgrade package file and then synchronizes the upgrade package file to the corresponding foreign storage bucket. Specifically, the domestic vehicle information management platform sets the corresponding country and region for each vehicle model to go overseas, the corresponding domestic storage bucket (such as Amazon Cloud and other third-party cloud service providers) and the storage path of the country and region. After the domestic vehicle information management platform downloads the upgrade package file based on the download link, it can query the associated vehicle model of the part to be upgraded based on the hardware part number in the relevant information of the upgrade package, and upload the upgrade package to the domestic storage bucket and storage path of the corresponding country and region according to the corresponding export country and region of the associated vehicle model (the upgrade package is still encrypted and signed at this time). If the part to be upgraded is exported to multiple countries and regions, the upgrade package corresponding to the part to be upgraded will also be synchronized to the domestic storage buckets and storage paths of different countries and regions at the same time. The domestic storage bucket synchronizes the upgrade package file corresponding to the part to be upgraded to the overseas storage bucket of the corresponding country and region, and keeps the folders and file paths of the domestic storage bucket and the foreign storage bucket completely consistent. In this way, the upgrade package file corresponding to the part to be upgraded is uploaded and stored in the foreign storage bucket of the export country and region corresponding to the associated vehicle model of the part to be upgraded.

[0094] Step 620, sending an upload request, upgrade package related information, and the domestic storage bucket and storage path of the export country and region corresponding to the associated vehicle model of the part to be upgraded to the domestic MAS platform, so that the domestic MAS platform uploads the upgrade package file corresponding to the part to be upgraded to the domestic storage bucket and storage path of the export country and region corresponding to the associated vehicle model of the part to be upgraded based on the upload request and upgrade package related information, so that the corresponding domestic storage bucket stores the upgrade package file and then synchronizes the upgrade package file to the corresponding foreign storage bucket.

[0095] In an embodiment of the present application, the domestic MAS platform can provide the domestic vehicle information management platform with the upgrade package name and download link corresponding to the part to be upgraded, and then the domestic vehicle information management platform can download the upgrade package and then upload it to the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded. In addition, the domestic vehicle information management platform can also provide the domestic MAS platform with a designated domestic storage bucket and storage path, so that the domestic MAS platform can directly upload the upgrade package file corresponding to the part to be upgraded to the designated domestic storage bucket and storage path, and then the domestic storage bucket will synchronize the upgrade package file to the corresponding foreign storage bucket, so as to upload and store the upgrade package file corresponding to the part to be upgraded in the foreign storage bucket corresponding to the export country and region of the associated vehicle model of the part to be upgraded.

[0096] Reference Figure 7 , Figure 7 A first interactive schematic diagram of a method for implementing cross-border transmission of an automobile OTA upgrade package is shown, including but not limited to the following steps:

[0097] S1. The overseas OTA platform sends a cross-border transmission request for the upgrade package and related information of the upgrade package to the domestic vehicle information management platform.

The upgrade package related information is used to determine the unique upgrade package file corresponding to the part to be upgraded. After receiving the cross-border request for the upgrade package, the domestic vehicle information management platform sends the upgrade package information corresponding to the part to be upgraded to the domestic MAS platform to query the upgrade package name and download link corresponding to the part to be upgraded. The domestic MAS platform returns the download address and upgrade package name of the encrypted upgrade package file to the domestic vehicle information management platform. The domestic vehicle information management platform downloads the upgrade package file with the upgrade package name based on the returned download link. The domestic vehicle information management platform also queries the associated vehicle model of the part to be upgraded based on the upgrade package related information, and then uploads the encrypted upgrade package file to the domestic storage bucket and storage path of the export country and region corresponding to the associated vehicle model. If the part to be upgraded is exported to multiple countries and regions, the upgrade package file will also be synchronized to the domestic storage bucket and corresponding storage path of each country and region corresponding to the export. The domestic storage bucket stores the upgrade package file, and synchronizes the upgrade package file to the corresponding foreign storage bucket, and keeps the folders and file paths of the domestic storage bucket and the foreign storage bucket completely consistent, so that the foreign storage bucket can store the upgrade package file corresponding to the parts to be upgraded. After the domestic vehicle information management platform downloads the upgrade package file, it sends the upgrade package information corresponding to the parts to be upgraded to the overseas OTA platform. Among them, the upgrade package information includes upgrade package related information, upgrade package name and upgrade package storage path. Therefore, the overseas OTA platform can update the upgrade package information based on the received upgrade package information, and then send the upgrade package name, upgrade package storage path and download link request to the overseas TSP to request the download link corresponding to the upgrade package file corresponding to the parts to be upgraded. After the overseas TSP requests the foreign storage bucket to generate a download link according to the upgrade package name and upgrade package storage path, it returns the download link to the overseas TSP.
