DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0025] BCM (Body Control Module) is a core component in the automotive electronic system that is responsible for driving, monitoring and controlling multiple electronic control units related to body functions. It manages body functions such as lighting, windows, door locks, seat control, etc. Through BCM, the car can achieve discrete control of a variety of electrical devices, thereby improving the car's intelligence level and driving convenience. BCM not only plays a key role in improving the driving experience, but is also responsible for real-time monitoring and management of various electrical functions of the car.
[0026] During the production and manufacturing process of the vehicle, the BCM also needs to write the relevant data of the vehicle lighting system into the BCM through flashing technology to improve its performance and certain functions. These functions include the turn signal missing light fast flash function that meets regulatory requirements. In order to ensure the normal operation of the BCM, accurate parameters must be entered; if the input parameters are incorrect, it may cause abnormal performance or imperfect functions.
[0027] However, the existing flash writing methods have the following problems: Complicated configuration: The current flashing method usually relies on the host computer provided by the manufacturer, and the operator needs to manually set it one by one according to the specific engine configuration, lamp power, vehicle platform, and lighting system configuration. Each parameter needs to be manually identified and selected, which makes the configuration process very complicated and prone to operational omissions.
[0028] Inefficiency: The flashing process is extremely time-consuming and cumbersome because it requires manual layer-by-layer comparison and selection of corresponding parameters. For up to 24 configuration items, manual comparison and selection one by one is not only time-consuming and labor-intensive, but also inefficient, and cannot meet the requirements of modern automobile production for efficiency and accuracy.
[0029] Unstable quality: The entire flashing process is completely dependent on manual operation, lacking an effective error prevention mechanism, and prone to identification errors or wrong selections. The influence of this human factor makes it impossible to effectively guarantee the quality of the flashing process, and there is a high operational risk.
[0030] In order to solve the above technical problems, according to an embodiment of the present application, a BCM automatic flashing method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0031] In this embodiment, a BCM automatic flashing method is provided. Figure 1 A flowchart of a BCM automatic flashing method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the process includes the following steps: Step S1, obtaining the BCM map number of the vehicle to be flashed.
[0032] Specifically, the files of all scheduled vehicle information are downloaded through the MES system, and the models containing BCM are screened out. For the screened models containing BCM, the BCM drawing number of each vehicle is obtained.
[0033] Step S3, searching for the target BCM diagram number corresponding to the BCM diagram number from the preset BCM flash database, and searching for the corresponding target power parameter according to the target BCM diagram number.
[0034] Specifically, the acquired BCM diagram number is used to query the BCM flash database and find the target BCM diagram number that matches the acquired BCM diagram number in the database. This step is the key to ensure that the BCM module can be configured correctly. Once the target BCM diagram number is determined, the target power parameters associated with the target BCM diagram number can be obtained from the database.
[0035] Step S5, generating flash configuration parameters corresponding to the vehicle to be flashed according to the target power parameters.
[0036] Specifically, according to the BCM-DID definition specification pre-defined by the technicians, the target power parameter is found in the corresponding DID number from the BCM-DID definition specification, and is converted into a flash configuration parameter that needs to be flashed subsequently according to the DID number. The flash configuration parameter is in the form of DID data.
[0037] Step S7, flashing the configuration parameters into the BCM hardware.
[0038] Specifically, hardware devices such as CAN can be used to flash configuration parameters into the BCM hardware to complete the data writing work.
[0039] The present embodiment provides a BCM automatic flashing method, which provides a unique identifier for subsequent flashing operations by obtaining the BCM drawing number of the vehicle to be flashed. Then, the corresponding target BCM drawing number is searched from the preset BCM flashing database, and the relevant target power parameters are obtained according to the target BCM drawing number. This step ensures that the required target parameters can be accurately matched and avoids errors in manual selection. Based on the acquired target power parameters, flashing configuration parameters that match the vehicle to be flashed are generated to ensure that the flashing operation can be configured according to specific needs. Finally, the generated flashing configuration parameters are accurately written into the BCM hardware to complete the flashing process. The whole process has a high degree of automation, which ensures the efficiency, accuracy and consistency of the flashing operation, effectively reduces human errors, and improves the reliability and stability of the BCM flashing operation.
[0040] Figure 2 The flowchart of step S1 provided in the embodiment of the present application may include the following steps: Step S11, obtaining the production code of the vehicle to be flashed.
[0041] Specifically, the information of all scheduled vehicles for the day is downloaded from the MES system, including the production code of each vehicle. The production code can be used as the unique identification code of the vehicle. The vehicle to be flashed in the embodiment of the present application refers to a vehicle of a BCM model, and flashing is performed on the vehicle of this model.
[0042] Step S13, according to the production code, search in the MES system to obtain the BCM drawing number corresponding to the production code.
[0043] Specifically, through this production code, the BCM drawing number of the corresponding vehicle can be found in the MES system, thereby obtaining detailed information on the corresponding parts. Note that each part corresponds to an independent drawing number.
[0044] and Figure 1 Compared with the embodiment shown in the figure, this embodiment can accurately identify the information of a specific vehicle by obtaining the production code of the vehicle to be flashed, thereby ensuring the accuracy and pertinence of subsequent processing. Then, the corresponding BCM drawing number is searched in the MES system according to the production code, reducing errors that may be caused by manual input or other search methods. In addition, the automated search significantly shortens the search time, improves work efficiency, and makes the production process smoother.
[0045] Figure 3 The flowchart of step S5 provided in the embodiment of the present application may include the following steps: Step S51, obtaining BCM-DID definition specifications.
[0046] Specifically, the BCM-DID definition specification refers to the establishment of a mapping relationship between parameters and unique identifiers (DID numbers). Here, the mapping relationship between various power parameters and identifiers is defined. The establishment of this mapping relationship enables different power parameters to be identified and managed through corresponding DID numbers, ensuring the unity and consistency of the system. After finding the corresponding identifier, it can be converted into DID data format to provide a data basis for subsequent operations.
[0047] Step S53, according to the target power parameters, determine the flash configuration parameters corresponding to the vehicle to be flashed from the BCM-DID definition specification; wherein the flash configuration parameters are in DID format.
[0048] Specifically, according to the target power parameter, find the corresponding DID number in the BCM-DID definition specification. Use the found DID number to construct the flash configuration parameters. The flash configuration parameters usually need to be organized in the form of DID, and the format may include: DID number: identifier, parameter value: actual value corresponding to the target power parameter, etc. Output the generated flash configuration parameters in an appropriate format, which can be JSON, XML or other formats suitable for parsing.
[0049] and Figure 1 Compared with the embodiment shown, this embodiment can achieve structured processing of vehicle BCM data by standardizing parameter acquisition and accurately matching flashing parameters. First, by obtaining the BCM-DID definition specification, it is ensured that subsequent operations are based on unified information, reducing errors caused by inconsistent parameters. Secondly, the flashing configuration parameters to be flashed are determined from the BCM-DID according to the target power parameters to ensure the accuracy and efficiency of the flashing. At the same time, the flashing configuration parameters output in the form of DID have a clear structure, which is convenient for subsequent operation and maintenance. In summary, the embodiment of the present application significantly improves the automation and intelligence of the flashing operation through automated and intelligent parameter generation.

[0051] Step S73, flashing the configuration parameters into the BCM hardware via the CAN device.
[0052] Specifically, the CAN network is a communication protocol widely used in automotive electronic systems. It can support real-time data transmission between multiple devices, send the flash configuration parameters to the CAN device through the CAN network, and then the CAN device sets the baud rate and network parameters, and flashes the flash configuration parameters into the BCM hardware to achieve effective control and optimization of vehicle functions.
[0053] and Figure 1 Compared with the embodiment shown in the figure, this embodiment achieves efficient data transmission and real-time response capability by sending the flash configuration parameters to the CAN device through the CAN network, and further flashing them into the BCM hardware. This method not only reduces transmission delays and supports simultaneous communication of multiple devices, but also enhances the reliability and security of the system, ensuring accurate data transmission in various environments. In addition, after the flash is completed, the system can verify the configuration consistency in the BCM through a feedback mechanism, thereby reducing the risk of failure. Overall, this embodiment improves the vehicle's response speed to operating instructions, achieves more flexible configuration management, and optimizes the user experience, making the vehicle functions more intelligent and personalized.
[0054] Figure 5 The flowchart of the abnormal prompt provided in the embodiment of the present application may include the following steps: Step S301, when the target BCM diagram number corresponding to the BCM diagram number and the target power parameter corresponding to the BCM diagram number are not found in the preset BCM flash database, an abnormal information is prompted.
[0055] Specifically, when performing a BCM flash database query, if the corresponding BCM drawing number and its target power parameters cannot be found, abnormal information should be prompted to help technicians screen for abnormal situations. Technicians can manually modify or complete the missing data and update it to the flash database to facilitate further automated flashing.
[0056] and Figure 1 Compared with the embodiment shown in the figure, this embodiment can timely identify data anomalies, actively trigger and display abnormal information according to the situation that the target BCM diagram number corresponding to the BCM diagram number and the target power parameter corresponding to the BCM diagram number are not found in the preset BCM flashing database. This embodiment can effectively improve the accuracy of data processing, avoid incorrect parameter flashing, and thus ensure the safety and reliability of the BCM flashing process.
[0057] Figure 6 The flowchart after the prompt exception is provided in the embodiment of the present application, and the process may include the following steps: Step S303, in response to the abnormal information, the target BCM diagram number that has not been found and the target power parameter that has not been found are updated to the BCM flash database, the target BCM diagram number corresponding to the BCM diagram number is re-searched, and the corresponding target power parameter is searched according to the BCM diagram number.
[0058] Specifically, according to the abnormal information, the technicians manually enter the target BCM diagram number and the target power parameter that have not been found, and update them to the BCM flash database to ensure the data in the BCM flash database is complete. After updating the BCM flash database, it is necessary to re-query the operation to confirm whether the target BCM diagram number and target power parameter have been correctly added to the database to ensure that the subsequent BCM flash work can proceed smoothly, thereby avoiding potential problems caused by missing or incorrect data.
[0059] and Figure 5Compared with the embodiment shown in the figure, this embodiment updates the target BCM diagram number and its corresponding target power parameter that have not been found according to the abnormal information, and rewrites this information into the BCM flash database before performing the search operation again. Through the updated database, the target BCM diagram number and target power parameter corresponding to the BCM diagram number can be successfully found, thereby ensuring that the subsequent BCM flash operation can proceed smoothly. This embodiment ensures the flexibility of the flash method and the real-time nature of the data by dynamically updating the database information, improves the accuracy and reliability of the flash process, and effectively avoids flash failures caused by missing or incorrect data.
[0060] Figure 7 The flowchart for generating a flash log provided in an embodiment of the present application may include the following steps: Step S91, flash the configuration parameters into the BCM hardware and generate the flash time.
[0061] Step S93, record the BCM map number, target power parameters, flash configuration parameters, flash time and flash results of the vehicle to be flashed in real time, generate a flash log, and upload the flash log to the server.
[0062] Specifically, the flash configuration parameters can be flashed into the BCM hardware by sending the flash configuration parameters to the CAN device through the CAN network, and then flashing the flash configuration parameters into the BCM hardware through the CAN device. Record the timestamp at the beginning of the flash operation to facilitate subsequent tracking and analysis. After the flash is completed, record the end time and calculate the time required for the flash. Monitor the flash process to ensure that the data is transmitted correctly and no errors occur. During the flash process, record the BCM drawing number, target power parameters, flash configuration parameters, flash time, and flash results in real time. Organize the collected information into a structured log file. The log file should contain all the necessary details to facilitate quick identification of problems. Finally, upload the generated log file to the server.
[0063] and Figure 1 Compared with the embodiment shown, this embodiment ensures that the parameters in the BCM hardware are accurately configured and the specific operation time is marked by writing the flash configuration parameters into the BCM hardware and recording the flash time. Next, key information such as the BCM drawing number, target power parameters, flash configuration parameters, flash time, and flash results of the vehicle to be flashed is recorded in real time, and a detailed flash log is generated. The flash log will then be uploaded to the server for storage and management. This embodiment not only enhances the traceability of the flash process by recording and uploading the flash log in real time, but also provides an important basis for subsequent troubleshooting and data analysis, improves transparency and controllability of operations, and helps to ensure the efficiency and reliability of BCM flash operations.
