Description

Technical Field

[0001] This application relates to the technical field of vehicle firmware upgrade, and particularly relates to a method, system and device for obtaining an upgrade strategy of vehicle firmware. Background Art

[0002] The cloud performs a full - scale OTA (On The Air) upgrade on the vehicle by releasing FOTA (Firmware On The Air) upgrade activities. The most important of these is the upgrade of the system firmware. For example, the firmware upgrade of the automotive electronic control unit ECU, that is, without changing the vehicle hardware, remotely upgrade the vehicle's driving assistance functions, chassis suspension, body control, etc.

[0003] The main processes of FOTA upgrade are vehicle information management, FOTA firmware package management, FOTA upgrade activity release management, and FOTA upgrade detection in sequence. Among them, processes such as vehicle information management, FOTA firmware package management, and FOTA upgrade activity release and management are the pre - processes of the FOTA upgrade detection process.

[0004] The existing FOTA upgrade detection process usually requires the cloud to obtain and verify the vehicle's basic information, vehicle part information, vehicle part version information, etc. according to the vehicle request parameters. After completing the vehicle information verification, it is also necessary to obtain the vehicle activities, and then obtain the vehicle upgrade activity information according to the vehicle information. Finally, the corresponding upgrade strategy information and ECU upgrade version information are obtained through the associated query of the upgrade activity information. Obviously, the current FOTA detection processing link is long and time - consuming, and it is necessary to interact with the data storage middleware multiple times to obtain data; this method cannot meet the performance requirements of a large number of detection requests under the control of server costs. Summary of the Invention

[0005] This application provides a method, system and device for obtaining an upgrade strategy of vehicle firmware to solve the technical problem that the upgrade detection process in the prior art has a long processing link and is time - consuming, so that it cannot meet the performance requirements of a large number of detection requests.

[0006] Specifically, this application provides a method for obtaining an upgrade strategy of vehicle firmware, including the following steps: S100: In response to an upgrade signal, obtain an upgrade list of the target vehicle and upgrade digests of each preset firmware; the upgrade list includes at least a list digest and an upgrade data packet.

[0007] S200: Determine whether the upgrade digest is consistent with the list digest. If they are consistent, obtain a preset decoding table; otherwise, perform exception handling.

[0008] S300: Decode the upgrade data packet according to the preset decoding table to obtain the upgrade strategies for each preset firmware.

[0009] In the above technical solution, the whole process focuses on the comparison of the digest value of the list and the efficient extraction of data decoding, greatly simplifying the high-concurrency real-time upgrade detection process, reducing the complexity of the real-time detection service, and thus reducing the subsequent operation and maintenance difficulty and cost, and greatly improving the concurrency performance of the real-time upgrade detection.

[0010] Further, before executing step S100, it includes: Obtain the current version information of each preset firmware and send an upgrade signal according to the current version information.

[0011] In the above technical solution, there is only this one network request throughout the process, making the entire upgrade process simpler and more efficient, saving time and resources, and reducing costs at the same time; in addition, obtaining the version information of each preset firmware can accurately determine whether there is an upgrade requirement, providing a reliable data basis for subsequent upgrade detection.

[0012] Further, step S100 further includes: Judge whether the upgrade list is successfully obtained. If successful, obtain the upgrade digest; otherwise, perform exception handling.

[0013] In the above technical solution, by judging whether the upgrade list is successfully obtained, it is possible to timely discover the situation where the list acquisition fails during the upgrade process. If the list acquisition fails, exception handling can be carried out in a timely manner, which can ensure the reliability and stability of the system.

[0014] Further, the obtaining of the upgrade digest in step S100 includes: Generate an upgrade digest according to the current version information.

[0015] In the above technical solution, the digest can be used as a summary of the version information, containing the key content of the version information. It can be used as a simplified representation of the version information, converting complex version information into a unique digest value, which can simplify the processing and storage of data, improve the manageability and usability of the system; and since the length of the digest value is shorter, compared with carrying a large amount of version information, the speed of transmitting and processing the digest is faster, which can improve the efficiency of upgrade detection and reduce resource consumption.

[0016] Further, the upgrade list at least further includes a version number. The obtaining of the preset decoding table in step S200 includes: Obtain the upgrade data packet and determine whether the obtaining is successful. If successful, obtain the version number according to the upgrade data packet, so as to obtain a preset decoding table according to the version number; otherwise, perform exception handling.

[0017] In the above technical solution, by obtaining the preset decoding table, the subsequent decoding process can be ensured to be accurate and error-free. The decoding rules and algorithms corresponding to the version number are stored in the decoding table, which can correctly convert the upgrade data packet into readable content; the preset decoding table is stored in the local cache. Using the decoding table in the local cache can avoid the operation of obtaining the decoding table from the external each time, reduce the network transmission and processing time, and thus improve the processing speed and optimize the system performance; in addition, if the upgrade data packet does not exist, corresponding actions can be taken through the corresponding exception handling to ensure the reliability of the system.

[0018] Further, the exception handling includes: Real-time monitor the upgrade activities of the target vehicle, so as to initialize the upgrade list according to the upgrade activities when the upgrade activities are monitored and the upgrade list obtaining fails.

[0019] And when the upgrade activities are monitored and the obtaining of the upgrade data packet fails, update the upgrade list according to the upgrade activities.

[0020] In the above technical solution, when the obtaining of the upgrade list fails, by real-time monitoring the vehicle upgrade activities and initializing or updating the upgrade list according to the upgrade activities, specific handling can be carried out for this situation, and specific solutions can be provided; and by automatically initializing or updating the upgrade list, the operation difficulty and cost can be greatly reduced, and manual intervention and errors can be reduced; in addition, by real-time monitoring the upgrade process, problems can be quickly discovered or responded to, and corresponding controls can be carried out to improve the stability and reliability of the system.

[0021] Based on the same concept, the present application also provides a system for obtaining an upgrade strategy of vehicle firmware, and the system includes: The first obtaining module: used to obtain the upgrade list of the target vehicle in response to the upgrade signal; the upgrade list at least includes a list summary and an upgrade data packet.

[0022] The second obtaining module: used to obtain the upgrade summaries of each preset firmware.

[0023] The first judgment module: used to judge whether the upgrade summary is consistent with the list summary, and when they are consistent, transfer to the third obtaining module; and when they are inconsistent, transfer to the exception handling module.

[0024] The third obtaining module: used to obtain a preset decoding table.

[0025] Fourth acquisition module: configured to decode the upgrade data packet according to the acquisition result of the third acquisition module, so as to obtain the upgrade strategies of each preset firmware.

[0026] In the above technical solution, through the comparison of the digest value of the manifest and the efficient data decoding and extraction, the whole process greatly simplifies the high-concurrency real-time upgrade detection process. This simplification reduces the complexity of the real-time detection service and further reduces the subsequent operation and maintenance difficulty and cost; at the same time, this simplification process also greatly improves the concurrency performance of the real-time upgrade detection, enabling the system to effectively handle a large number of upgrade detection requests, improving the overall upgrade detection efficiency and user experience.

[0027] Further, the third acquisition module includes: First acquisition unit: configured to acquire the upgrade data packet.

[0028] Judgment unit: configured to judge whether the upgrade data packet is successfully acquired. When successful, it transfers to the second acquisition unit; and when not successful, it transfers to the exception handling module.

[0029] Second acquisition unit: configured to obtain the version number according to the upgrade data packet, and obtain the preset decoding table according to the version number.

[0030] In the above technical solution, the system can directly obtain the required upgrade data packet from the upgrade manifest without additional network requests or consuming time and resources; by obtaining the version number, the system can accurately locate the corresponding preset decoding table for subsequent data decoding, which can ensure that the system adopts the correct decoding rules and algorithms, providing the accuracy and reliability of subsequent decoding; and when the upgrade data packet acquisition fails, it will transfer to exception handling, thus ensuring the stability and reliability of the system.

[0031] Further, the system further includes: Signal module: configured to obtain the current version information of each preset firmware and send an upgrade signal according to the current version information.

[0032] Second judgment module: configured to judge whether the upgrade manifest is successfully acquired. When successful, it transfers to the second acquisition module; and when not successful, it transfers to the exception handling module.

[0033] Exception handling module: configured to monitor the upgrade activities of the target vehicle in real time. When an upgrade activity is monitored and the upgrade manifest acquisition fails, initialize the upgrade manifest according to the upgrade activity; and when an upgrade activity is monitored and the upgrade data packet acquisition fails, update the upgrade manifest according to the upgrade activity.

[0034] In the above technical solution, there is only one network request to send the upgrade signal throughout the process, making the entire upgrade process simpler and more efficient, saving time and resources while reducing costs; by determining whether the upgrade list is successfully obtained, the system can promptly detect the situation of failed list acquisition and take corresponding exception handling measures to provide reliable and stable services; by initializing or updating the upgrade list in a timely manner, problems can be quickly discovered or responded to, and corresponding controls can be carried out to improve the stability and reliability of the system.

The whole process of the present application revolves around the comparison of the summary values of the list and the efficient extraction of data decoding, greatly simplifying the high-concurrency real-time upgrade detection process, reducing the complexity of the real-time detection service, and further reducing the subsequent operation and maintenance difficulty and cost, and greatly improving the concurrency performance of the real-time upgrade detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a flowchart of the method for obtaining the upgrade strategy of the vehicle firmware as described in the present application.

[0038] Figure 2 is Figure 1 The system framework diagram of the method for obtaining the upgrade strategy of the vehicle firmware as described above. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The present application provides a method, a system and a device for obtaining the upgrade strategy of vehicle firmware to solve the technical problem that the processing link of the upgrade detection process in the prior art is long and time-consuming, resulting in the inability to meet the performance requirements of a large number of detection requests.

[0040] The following further describes in detail a method, a system and a device for obtaining the upgrade strategy of vehicle firmware according to the present application with reference to specific embodiments and the accompanying drawings.

[0041] Embodiment 1:

[0042] Please refer toFigure 1 The present application provides a method for obtaining an upgrade strategy for vehicle firmware, comprising the following steps: S100: In response to the upgrade signal, an upgrade list of the target vehicle and an upgrade summary of each preset firmware are obtained.

[0043] Furthermore, before executing step S100, the following steps are included: Obtain the current version information of each preset firmware, and send an upgrade signal according to the current version information.

[0044] In this embodiment, the preset firmware is set to ECU, and the vehicle side obtains the current version information of each ECU in the vehicle through the in-vehicle diagnostic protocol; then the vehicle side carries the current version information of each ECU in the vehicle to initiate a FOTA upgrade detection request to the cloud FOTA upgrade detection service, which is the upgrade signal.

[0045] In the above technical solution, the entire process only requires this one network request, making the entire upgrade process simpler and more efficient, saving time and resources while reducing costs; in addition, obtaining the version information of each preset firmware can accurately determine whether there is an upgrade requirement, providing a reliable data basis for subsequent upgrade detection.

[0046] Furthermore, the step S100 further includes: Determine whether the upgrade list is obtained successfully. If successful, obtain the upgrade summary; otherwise, perform exception handling.

[0047] In this embodiment, in response to the FOTA upgrade detection request, the cloud FOTA upgrade detection service obtains the upgrade list of the shared cache through the VIN, and determines whether the upgrade list has been successfully obtained. If successful, it will further obtain the upgrade summary; otherwise, it will perform exception handling. Among them, VIN (Vehicle Identification Number) is a unique identifier used to identify a specific vehicle. VIN usually consists of 17 characters and contains information about the vehicle manufacturer, production location, production year, etc.

[0048] Among them, the predecessor of the upgrade list is the vehicle FOTA upgrade detection topology list, which includes vehicle basic information (VIN, vehicle model information, etc.), vehicle extended information (vehicle test identification, encryption scheme material data), vehicle current parts version information list and vehicle current parts available version information list; by encoding the topology list, the upgrade list is obtained, and the upgrade list is stored in a shared cache.

[0049] The upgrade list at least includes a list summary, a topology list data dictionary code table version number (i.e., the version number described below), and list data (the same as the upgrade data packet described below).

[0050] It should be noted that the topology list data dictionary code table version number can be designed according to the actual situation of specific projects. The principle is to extract the common parts as much as possible and form a dictionary table, and compress the list data in the shared cache as much as possible to ensure that more ECU upgrade version data can be accommodated. Compared with the traditional JSON data storage structure in the past, the data volume is smaller and lighter, and under certain network bandwidth limitations, it can accommodate more ECU upgrade version information than the JSON data structure. That is, on the premise of meeting high-concurrency performance, it can easily handle the upgrade activity scenarios of more ECUs in the vehicle being upgraded simultaneously in the future, avoiding multiple queries involved in traditional multi-module data storage, and thus improving the high throughput of the shared cache service.

[0051] In the above technical solution, by determining whether the upgrade list is successfully obtained, it is possible to timely detect the situation of failure to obtain the list during the upgrade process. If the list acquisition fails, exception handling can be carried out in a timely manner, which can ensure the reliability and stability of the system.

[0052] Further, the obtaining of the upgrade summary in step S100 includes: Generating an upgrade summary based on the current version information.

[0053] In this embodiment, an upgrade summary is generated based on the current version information carried by the vehicle.

[0054] In the above technical solution, the summary can be used as a summary of the version information, containing the key content of the version information. It can be used as a simplified representation of the version information, converting complex version information into a unique summary value, which can simplify the processing and storage of data, improve the manageability and usability of the system; and since the length of the summary value is shorter, compared with carrying a large amount of version information, the speed of transmitting and processing the summary is faster, which can improve the efficiency of upgrade detection and reduce resource consumption.

[0055] After obtaining the upgrade list and the upgrade summary, step S200 can be executed.

[0056] S200: Determine whether the upgrade summary is consistent with the list summary. If they are consistent, obtain a preset decoding table; otherwise, perform exception handling.

[0057] Further, the upgrade list at least further includes a version number. The obtaining of the preset decoding table in step S200 includes: Obtain the upgrade data packet and determine whether the acquisition is successful. If successful, obtain the version number according to the upgrade data packet, so as to obtain a preset decoding table according to the version number; otherwise, perform exception handling.

[0058] In this embodiment, obtain the upgrade data packet in the upgrade list and determine whether the acquisition is successful. If successful, retrieve the preset decoding table in the local cache according to the version number of the dictionary code table.

[0059] It should be noted that the preset decoding table is stored in the local cache. Using the decoding table in the local cache can avoid the operation of obtaining the decoding table from the external every time, reduce the network transmission and processing time, and thus improve the processing speed and optimize the system performance; among them, multiple decoding tables are stored in the list data code table of the local cache, and each decoding table includes information such as attribute codes, value types, and value lengths corresponding to different version numbers.

[0060] In the above technical solution, by obtaining the preset decoding table, the subsequent decoding process can be ensured to be accurate and error-free. The decoding table stores the decoding rules and algorithms corresponding to the version number, and can correctly convert the upgrade data packet into readable content; in addition, if the upgrade data packet does not exist, corresponding actions can be taken through corresponding exception handling to ensure the reliability of the system.

[0061] Further, the exception handling includes: Real-time monitor the upgrade activities of the target vehicle, so as to initialize the upgrade list according to the upgrade activities when the upgrade activities are monitored and the acquisition of the upgrade list fails.

[0062] And when the upgrade activities are monitored and the acquisition of the upgrade data packet fails, update the upgrade list according to the upgrade activities.

[0063] In this embodiment, if the acquisition of the upgrade list or the upgrade data packet fails, the initialization or update process of the list will be initiated asynchronously, and an upgrade version update response message without an upgrade will be immediately responded to the vehicle end.

[0064] Among them, the update of the upgrade list depends on the FOTA upgrade detection service to monitor relevant FOTA upgrade detection activities, and then complete the update of the FOTA upgrade detection list of relevant vehicles.

[0065] In the above technical solution, when the acquisition of the upgrade list fails, by real-time monitoring the vehicle upgrade activities and initializing or updating the upgrade list according to the upgrade activities, specific handling can be carried out for this situation, and specific solutions can be provided; and by automatically initializing or updating the upgrade list, the operation difficulty and cost can be greatly reduced, and manual intervention and errors can be reduced; in addition, by real-time monitoring the upgrade process, problems can be quickly discovered or responded to, and corresponding control can be carried out to improve the stability and reliability of the system.

[0066] After obtaining the preset decoding table, step S300 can be executed.

[0067] S300: Decode the upgrade data packet according to the preset decoding table to obtain the upgrade strategies for each preset firmware.

[0068] In this embodiment, the obtained upgrade data packet is decoded by the obtained preset decoding table to obtain the current upgraded ECU version data and upgrade strategy information, and an upgrade detection response message is returned to the vehicle terminal according to specific project requirements, so that the vehicle terminal can perform further firmware upgrade work according to the obtained upgrade strategy information.

[0071] In this embodiment, the vehicle terminal obtains the current version information of each ECU in the vehicle through the on-board diagnostic protocol, and the vehicle terminal carries the current version information of each ECU in the vehicle to initiate a FOTA upgrade detection request (i.e., the upgrade signal) to the cloud FOTA upgrade detection service.

[0072] Among them, there is only one network request for sending the upgrade signal in the whole process, making the whole upgrade process simpler and more efficient, so as to save time and resources and reduce costs at the same time.

[0075] Second judgment module: used to judge whether the upgrade list is obtained successfully, and when it is successful, transfer to the second acquisition module; and when it is not successful, transfer to the exception handling module.

[0077] Among them, the upgrade summary is generated from the current version information of each ECU.

[0083] In this embodiment, the preset decoding table in the local cache is retrieved according to the dictionary code table version number (i.e., the version number).

[0084] In the above technical solution, the system can directly acquire the required upgrade data packet from the upgrade list without additional network requests or consuming time and resources; by acquiring the version number, the system can accurately locate the corresponding preset decoding table for subsequent data decoding, which can ensure that the system adopts the correct decoding rules and algorithms, providing the accuracy and reliability of subsequent decoding; and when the acquisition of the upgrade data packet fails, it will transfer to exception handling, thus ensuring the stability and reliability of the system.

[0085] The fourth acquisition module: used to decode the upgrade data packet according to the acquisition result of the third acquisition module to acquire the upgrade strategies of each preset firmware.

[0086] In this embodiment, the acquired upgrade data packet is decoded by the acquired preset decoding table to obtain the current upgraded ECU version data and upgrade strategy information, and an upgrade detection response message is returned to the vehicle end according to specific project requirements, so that the vehicle end can perform further firmware upgrade work according to the acquired upgrade strategy information.

[0087] The system further includes: The exception handling module: used to monitor the upgrade activities of the target vehicle in real time, and when an upgrade activity is monitored and the acquisition of the upgrade list fails, initialize the upgrade list according to the upgrade activity; and when an upgrade activity is monitored and the acquisition of the upgrade data packet fails, update the upgrade list according to the upgrade activity.

[0088] In this embodiment, if the upgrade list or the upgrade data packet fails to be obtained, the initialization or update process of the list will be initiated asynchronously, and the vehicle-end response message indicating no upgrade version update will be immediately sent in response.

[0089] Among them, the update of the upgrade list depends on the FOTA upgrade detection service listening to relevant FOTA upgrade detection activities to complete the update of the relevant vehicle FOTA upgrade detection list.

[0090] In the above technical solution, by initializing or updating the upgrade list in a timely manner, problems can be quickly discovered or responded to, and corresponding control can be carried out, improving the stability and reliability of the system.
