[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: collecting flash log files, wherein the flash log files are generated based on vehicle diagnostic messages; parsing the flash log files to obtain message information; matching a preset message library according to the message information to obtain a target message; performing vehicle flash monitoring according to the message information and the target message to obtain a monitoring result.

[0052] The flashing process of car flashing software is to transfer new or updated firmware (software) to the car electronic control unit (ECU). This process is crucial for vehicle maintenance, upgrades and functional improvements. In the process of car flashing, parsing of diagnostic messages and flashing monitoring are key steps to ensure the correct flashing of firmware. However, existing technologies usually rely on manual review of relevant protocols to parse diagnostic messages, resulting in low efficiency and poor accuracy in vehicle flashing monitoring. Therefore, how to improve the efficiency and accuracy of vehicle flashing monitoring is a problem that needs to be solved urgently.

[0053] This application can quickly and accurately obtain message information by collecting and parsing flash log files, and then accurately match the target message in the preset message library according to the message information, so as to perform vehicle flash monitoring in combination with the message information, and can quickly and accurately obtain monitoring results. It overcomes the technical defects of the prior art that the monitoring efficiency and accuracy of vehicle flash are low due to manual viewing of relevant protocols to parse diagnostic messages, and can effectively improve the monitoring efficiency and accuracy of vehicle flash.

[0054] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle flash monitoring device, etc. The following takes the vehicle flash monitoring device as an example to illustrate this embodiment and the following embodiments.

[0055] Based on this, the embodiment of the present application provides a vehicle flash monitoring method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle flash monitoring method of the present application.

[0056] In this embodiment, the vehicle flash monitoring method includes steps S10 to S40:

[0057] Step S10, collecting a flash log file, wherein the flash log file is generated based on a vehicle diagnostic message.

[0058] It should be noted that the flash log file refers to a record file automatically generated by the vehicle's diagnostic system during the vehicle's diagnostic flash process. This file records all diagnostic messages during the flash process, including vehicle diagnostic request messages and vehicle diagnostic response messages. The flash log file usually contains information such as the message identifier, timestamp, and data bytes, which is not specifically limited in this embodiment.

[0059] In a feasible implementation manner, before step S10, it also includes: acquiring in real time the request message, response message and error information sent and received during the vehicle flashing process; and generating a flashing log file according to the request message, the response message and the error information.

[0060] It should be noted that the request message refers to the message sent by the vehicle to the diagnostic system to request diagnostic services, while the response message is the reply of the diagnostic system to the request message. Error information usually includes any abnormal conditions that occur during the flashing process, which is crucial for subsequent flashing monitoring. By obtaining this information in real time and generating a flashing log file, the real-time and accuracy of the monitoring process can be ensured.

[0061] Step S20, parsing the flash log file to obtain message information.

[0062] It should be noted that the collected flash log files can be in .asc or .csv format. Different parsing strategies can be used for flash log files of different formats. For example, for .asc files, you can read line by line and use a specific delimiter to split the data, while for .csv files, you can use commas as delimiters to extract data. The parsing algorithm needs to be able to handle various possible message formats and encoding methods to ensure that message information can be accurately extracted from different types of flash log files.

[0063] It is understandable that the message information includes key information such as the message identifier, timestamp, data bytes, etc., and this embodiment does not impose any specific limitation on this.

[0064] In a feasible implementation, the step S20 may include: identifying the vehicle diagnostic request message and the vehicle diagnostic response message in the flash log file; extracting the message identifier, message timestamp and message data bytes of the vehicle diagnostic request message and the vehicle diagnostic response message respectively; and using the vehicle diagnostic request message, the vehicle diagnostic response message and the corresponding message identifier, message timestamp and message data bytes as message information.

[0065] It should be noted that the flash log file usually contains a large number of diagnostic messages, such as vehicle diagnostic request messages and vehicle diagnostic response messages. The message identifier, or message ID, is a code that can uniquely identify each message. The message timestamp records the specific time when the message is sent or received. The message data bytes contain the specific content of the message. By extracting these key information, accurate data support can be provided for subsequent message matching and monitoring.

[0066] Step S30, matching a preset message library according to the message information to obtain a target message.

[0067] It should be noted that the preset message library, that is, the preset standard flashing process message library, refers to a database containing all possible messages in the standard flashing process. The message library is arranged in the order of the flashing process, and each message is associated with a specific flashing step, ensuring the correctness and integrity of the flashing process. The message information in the preset message library includes the message identification, timestamp, data bytes, etc. This information is matched with the message information in the flashing log file to verify whether the flashing process is carried out according to the established process. In this way, any deviations or errors in the flashing process can be effectively detected, thereby ensuring the quality and reliability of vehicle flashing.

[0068] In a feasible implementation, the step S30 may include: matching the message identifier in the message information with the identifiers of each message in the preset message library to obtain a matching identifier; and using the message corresponding to the matching identifier as the target message.

[0069] It should be noted that the matching process is achieved by comparing the message identifier in the message information with the message identifier stored in the preset message library. If a matching identifier is found, the message is considered to be the target message, which is used to verify whether the message corresponding to the message identifier in the message information complies with the expected flashing process. If a matching identifier is not found in the preset message library, it indicates that there may be anomalies in the flashing process, which requires further analysis and processing. In this way, it can be ensured that each message is strictly verified, thereby improving the accuracy and reliability of the flashing process.

[0070] Step S40, performing vehicle flash monitoring according to the message information and the target message to obtain a monitoring result.

[0071] It should be noted that the monitoring process includes but is not limited to checking whether the timestamp of the message conforms to the preset flashing time sequence, and whether the message data bytes are consistent with the data in the preset message library. If all messages conform to the expected flashing process, the monitoring results indicate that the flashing process is normal and the vehicle flashing is successful. Conversely, if the timestamp sequence is wrong or the data bytes do not match, the monitoring results will point out the problems in the flashing process, thereby providing maintenance personnel with clear fault diagnosis information. The monitoring results can be presented in a variety of forms, for example, displaying the real-time status of the flashing process through a graphical interface, or generating a detailed monitoring report for subsequent analysis. In addition, the monitoring system can also automatically perform some preset operations based on the monitoring results, such as automatically stopping the flashing process when an error is detected to prevent potential damage. Through such a monitoring mechanism, the efficiency and safety of vehicle flashing can be significantly improved.

[0072] In a feasible implementation manner, after step S40, it also includes: when the monitoring result is a flash interruption, comparing the message information with the target message to obtain a comparison result; locating the interruption point and analyzing the interruption cause according to the comparison result, and generating a flash report.

[0073] It should be noted that flash interruption refers to the failure of the flash operation to be completed due to various reasons during the vehicle flash process. This may be caused by hardware failure, software error, communication interruption or other unexpected events. When an interruption occurs, it is necessary to quickly locate the specific location of the interruption and analyze the cause of the interruption so as to take appropriate measures to repair it.

[0074] It is understandable that when any error message or abnormal behavior is identified in the flash log, the corresponding message is compared with the standard process of the target message to determine the possible problem point.

[0075] In the specific implementation, during the flashing process, real-time feedback on the progress of the flashing is provided, such as the number and total number of data blocks currently being transmitted; after the flashing is completed, a summary report is output, including whether the flashing is successful, firmware version information, flashing time, etc.; if there is an interruption or failure during the flashing process, the flashing log is analyzed to determine the interruption point and possible causes; the progress and results of the flashing process are displayed through charts or graphical interfaces, so that users can intuitively understand the flashing status; a detailed flashing report is generated, including detailed information on all key steps, screenshots of any errors or exceptions, and suggested solutions; based on the flashing results, suggestions for subsequent operations are provided, such as re-flashing, contacting technical support, or executing specific diagnostic procedures, which can significantly improve the automation and accuracy of flashing process monitoring, reduce manual intervention, reduce error rates, and quickly locate the causes of flashing interruptions.

[0076] The present embodiment provides a vehicle flashing monitoring method, which first collects a flashing log file, wherein the flashing log file is generated based on a vehicle diagnostic message; parses the flashing log file to obtain message information; matches a preset message library according to the message information to obtain a target message; and performs vehicle flashing monitoring according to the message information and the target message to obtain a monitoring result, thereby effectively improving the monitoring efficiency and accuracy of the vehicle flashing.

[0077] In summary, this embodiment can quickly and accurately obtain message information by collecting and parsing the flash log file, and then accurately match the target message in the preset message library according to the message information, so as to perform vehicle flash monitoring in combination with the message information, and quickly and accurately obtain the monitoring results. This overcomes the technical defects of the prior art that the monitoring efficiency and accuracy of vehicle flash are low due to the manual viewing of relevant protocols to parse the diagnostic message, and can effectively improve the monitoring efficiency and accuracy of vehicle flash.

[0078] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , the step S40 further includes steps S401-S402:

[0079] Step S401, performing message sequence verification and message content verification according to the message information and the target message, and obtaining a message sequence verification result and a message content verification result.

[0080] It should be noted that message sequence verification refers to checking whether the time sequence of messages during the flashing process is correct. Message sequence verification can be achieved by comparing the timestamps of the messages to obtain the message sequence verification result.

[0081] It can be understood that message content verification refers to verifying whether the message data bytes are consistent with the data in the preset message library to ensure the correctness of the message content.

[0082] In a feasible implementation, step S401 specifically includes: determining the message content and the message timestamp based on the message information; determining the message sequence information based on the message timestamp; determining the message sequence verification result based on the message sequence information and the target message; determining the message content verification result based on the message content and the target message.

[0083] It should be noted that in this embodiment, the message sequence verification is achieved by comparing the timestamps of the messages. The message sequence information can be determined according to the message timestamp sequence. If the message sequence information does not conform to the standard flashing process corresponding to the target message, it indicates that there may be a time deviation in the flashing process, which may be caused by network delay, message loss or other reasons. In this way, the time deviation problem in the flashing process can be discovered and corrected in time to ensure the smooth progress of the flashing.

[0084] It is understandable that message sequence information refers to the time sequence followed by the message during the data transmission process. In vehicle flash monitoring, message sequence information is crucial because it ensures the correctness and integrity of the flash operation. If the order in which the messages are sent is inconsistent with the preset flash process, it may cause flash failure or abnormal function of the vehicle system. Therefore, the monitoring system needs to be able to accurately verify the order of the messages to ensure that each message is processed in the correct order. In addition, the verification of message sequence information can also help identify and eliminate problems caused by network delays, message loss or repeated transmission.

[0085] It is worth noting that message content verification ensures the accuracy of the message content by comparing the message data bytes with the data of the target message in the preset message library. If the message content is inconsistent with the data of the target message, it means that the message may have been tampered with or damaged during transmission, and further inspection and processing are required. Through such a double verification mechanism, the integrity of the vehicle flashing process and the accuracy of the data can be ensured, thereby improving the reliability of the flashing process. This monitoring method can greatly reduce vehicle failures caused by flashing errors, improve vehicle maintenance efficiency and user experience.

[0086] Step S402, performing vehicle flash monitoring according to the message sequence verification result and the message content verification result to obtain a monitoring result.

[0087] It should be noted that if the message sequence verification results and the message content verification results indicate that both the message sequence and content meet the preset standards, the monitoring results will show that the flashing process is normal and the vehicle flashing is successful.

[0088] It is understandable that if there are inconsistencies, the monitoring results will show that the refresh is interrupted / failed, and the system will provide interruption point location and interruption cause analysis to help maintenance personnel quickly locate the problem and take corresponding measures. The monitoring system can also automatically perform preset operations based on the monitoring results, such as automatically stopping the flashing process when an error is detected to prevent potential damage. By providing real-time feedback on the progress of the flashing, such as the number and total number of data blocks currently being transmitted, and outputting a summary report after the flashing is completed, including whether the flashing is successful, firmware version information, flashing time, etc., the efficiency and safety of vehicle flashing can be significantly improved.

[0089] In this embodiment, by performing message sequence verification and message content verification based on the message information and the target message, a double verification mechanism can be used to ensure the integrity of the vehicle flashing process and the accuracy of the data. Then, the vehicle flashing monitoring is performed based on the message sequence verification results and the message content verification results to obtain the monitoring results, which can effectively improve the accuracy of the monitoring results.

[0090] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle flash monitoring method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
