[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and not to limit the present application.

[0048] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings and specific embodiments of the specification.

[0049] It should be noted that the execution subject of the 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 and the like, or an electronic device, a vehicle communication parameter configuration device and the like capable of realizing the above functions. The vehicle communication parameter configuration device is taken as an example to describe the embodiment and each of the following embodiments.

[0050] The embodiment of the present application provides a vehicle communication parameter configuration method, referring to Figure 1 , Figure 1 The flowchart of the first embodiment of the present application is shown in the figure.

[0051] In the embodiment, the vehicle communication parameter configuration method comprises:

[0052] Step S10: Obtain a DBC file.

[0053] It should be noted that the DBC file, full name Database CAN, is a file used to describe the data format in the CAN (Controller Area Network) network. The main function of the DBC file is to provide a standardized method to describe and analyze CAN messages, so that CAN message definitions can be shared and exchanged in different development environments, and data consistency between different devices and platforms is ensured. The DBC file defines the information of each frame message in CAN communication, such as message name, ID, message type, message period, data field length, signal definition and the like. It allows to identify part or all of the data in the CAN frame, including identification name, scaling, offset and definition information. The DBC file provides a standardized description method for data communication on the automobile CAN bus, so that different electronic control units (ECUs) can exchange data according to uniform rules.

[0054] It can be understood that the parsing process of the DBC file in the embodiment is the starting point of the automatic configuration process. By parsing the DBC file, the necessary message information can be automatically extracted. In the DBC file, the information of the message type that each node can receive or process is mainly distributed in the following parts: network node definition (BU): this part defines the name and attributes of each electronic control unit (ECU) in the CAN network, i.e., the node, although it does not directly list the message types processed by the node, but provides the basic information of the node; message frame definition (BO): BO record definition defines the specific messages transmitted on the CAN network, each message definition includes the CAN ID, size, sending node and other information of the message, and the receiving capability of the node usually corresponds to the message type it can send; filter rule (FILTER): if the DBC file contains a filter rule, the FILTER record will define the rules for the node to receive messages, which are based on the CAN ID or other attributes of the message.

[0055] It should be understood that in actual application, the software or firmware of the node will usually configure the filter rules of its CAN controller according to these definitions in the DBC file, so as to determine which message types the node can receive and process. The configuration of the node can also include the response logic to specific messages or signals, which is implemented based on the information provided in the DBC file.

[0056] Step S20: obtaining communication configuration update information according to the DBC file.

[0057] It should be noted that the existing CAN communication filter frame configuration process is usually performed manually by the developer according to the DBC file to generate relevant code, which not only has high technical requirements, but also is very tedious, and requires deep understanding of the CAN protocol and specific hardware. Manual configuration of filter frames increases the workload of developers in project development and later maintenance, and each time a node is added or modified in the CAN network, the filter rules need to be reconfigured, which undoubtedly increases the workload. In addition, since the configuration process relies on manual operation, there is a possibility of error. In order to overcome the above difficulties, the embodiment replaces manual operation with multiple automatic scripts to reduce the requirement of developers to understand the CAN protocol and hardware, and to improve the speed of the configuration update process.

[0058] In an embodiment, the obtaining of the communication configuration update information according to the DBC file comprises: obtaining CAN communication node identification and filter frame configuration data corresponding to the CAN communication node according to the DBC file; and obtaining the communication configuration update information according to the filter frame configuration data and the communication system configuration parameter backup table.

[0059] It can be understood that the communication configuration update information herein refers to the nodes participating in the configuration update in the current round of update and the corresponding node filter frame setting content. Obtaining the communication configuration update information generally includes two stages. In the first stage, the nodes participating in the configuration update and the corresponding configuration parameters of the nodes in the file are parsed through the corresponding OBC file parsing script, and a configuration update table is formed. In the second stage, the configuration parameter update table is compared with the locally stored configuration parameter backup, and the nodes with changed configuration and the change content can be obtained. According to the comparison result, a configuration update file in the MCAL format is generated, which is used as the communication configuration update information.

[0060] It should be understood that the MCAL provides a standardized hardware abstraction interface, so that the upper layer software can access hardware resources in a unified manner. The file in the MCAL format can be directly recognized and processed by the system, and the hardware configuration and initialization process is automated, which enables the parameter update process to be completed at one step.

[0061] Step S30: configuring the communication parameters of the vehicle according to the communication configuration update information to complete the automatic update of the vehicle communication system.

[0062] It can be understood that since the MCAL format communication configuration update information that can be directly overwritten into the corresponding node file path has been obtained in the foregoing steps, the update of the configuration parameters can be performed after the file path corresponding to each CAN node is determined.

[0063] In an embodiment, the communication configuration update information configures the communication parameters of the vehicle to complete the automatic update of the vehicle communication system, including: determining a file path of the communication parameter update according to the communication configuration update information; overwriting the communication configuration update information to the file path; restarting the vehicle communication system and performing a configuration update compatibility test; when the compatibility test passes, updating the communication system configuration parameter backup table according to the communication configuration update information to complete the update of the configuration information backup.

[0064] It should be noted that after the configuration parameters are overwritten, a compatibility test needs to be performed to ensure that the current configuration can be correctly used. When the test fails, the backup configuration parameters need to be rolled back to avoid the failure of the update process affecting the subsequent use.

[0065] It can be understood that before the vehicle is shipped, the manufacturer will define a series of test cases according to the functional requirements of the vehicle communication system, to ensure that all key functions and communication scenarios are covered. By calling these test cases, the index results and compatibility of the new configuration parameters under different environmental conditions can be simulated. For example, the new configuration parameters are tested, and the performance indicators under different environmental conditions, such as transmission rate, delay, packet loss rate, error rate, etc. are collected. By comparing the performance indicators before the configuration parameter update, it can be determined whether the current version of the configuration parameter is appropriate.

[0066] It should be understood that when the test passes, it can be considered that the current configuration update process is successful, so the locally saved backup configuration parameters can be updated together to ensure that the backup configuration parameters are consistent with the configuration parameters currently used in the vehicle communication system, avoiding problems caused by configuration differences, and saving the time of manually updating the backup information.

[0067] The embodiment provides a vehicle communication parameter configuration method. The embodiment first obtains a DBC file; obtains communication configuration update information according to the DBC file; and configures the communication parameters of the vehicle according to the communication configuration update information, to complete the automatic update of the vehicle communication system.

[0068] As can be seen from the above, the application parses the DBC file to obtain the identification of the CAN communication node and the filter frame configuration data, and then compares the backup communication system configuration parameters to identify the configuration that needs to be updated. Then, the update is converted into an MCAL format and directly overwritten into the vehicle communication system. Before the update is completed, the system will restart and perform a compatibility test to ensure the effectiveness of the update process, and update the backup table of the configuration parameters after passing the test, to ensure the accuracy and security of the configuration information. The vehicle communication parameter configuration method improves the update efficiency and accuracy through an automatic process, ensures the accuracy of the configuration and the stability of the system, reduces the manual maintenance work, reduces the maintenance cost, and enhances the security and traceability of the data.

[0069] Reference Figure 2 , Figure 2 FIG. 2 is a flowchart of a second embodiment of the vehicle communication parameter configuration method of the application. Based on the first embodiment described above, the second embodiment of the vehicle communication parameter configuration method of the application is proposed.

[0070] In the embodiment, the step S20 comprises:

[0071] Step S201: Identify and record the CAN communication node identification in the DBC file through the DBC parsing script.

[0072] It should be noted that the principle of DBC parsing script is based on the DBC (Database for CAN) file format. Since the DBC file is a standardized format, specific keywords and formats are used to organize information. In the specific process, the script first identifies and records the structure and format of the DBC file, including header information, message definition, signal definition, etc., and then according to the specification of the DBC file, the script parses the keywords in the file, such as BO (Bus Object, message definition) and SG (SignalGroup, signal definition), and then extracts the properties of each message and signal, including but not limited to CAN ID, message name, signal name, data length, start bit, data type, unit, etc., and then structures the data, converts the parsed data into a structured format such as dictionary, list or object, for further processing and analysis, and finally the script executes specific logic according to the parsing results, such as generating filtering rules, identifying communication nodes, extracting message frame definition information, etc. Through these principles, the DBC parsing script can automatically extract key information from the DBC file and provide structured data support for configuration updates of vehicle communication systems.

[0073] It can be understood that identifying node identification is not only for positioning data, but also to ensure that the correct configuration can be applied to the specific node in the subsequent steps, which is equivalent to only retaining the nodes participating in the update. In the subsequent steps, according to the CAN communication node sequence determined by the sorting of the nodes participating in the update here, it is convenient for the comparison and update of the subsequent configuration parameters.

[0074] Step S202: Obtain the message frame definition information under the CAN communication node identification.

[0075] It should be noted that each CAN node may need to receive or send different message frames, and the message frame definition information includes but is not limited to the ID, size, transmission frequency and contained signals of the message, etc. In the OBC file, the message frame definition information corresponding to each node participating in the configuration update is determined by the node ID.

[0076] Step S203: Obtain the filter frame configuration data corresponding to the CAN communication node according to the message frame definition information.

[0077] It can be understood that according to the message frame information and the communication needs of the node, it can be determined which message frames need to be received or sent by the node, so as to determine the filter frame configuration rule of the node, and according to the filter rule, a filter list is generated for each node, including the message ID list allowed to receive and the message ID list to be ignored, so as to obtain the filter frame configuration data corresponding to the CAN communication node.

[0078] Step S204: According to the filter frame configuration data, the to-be-updated configuration data table arranged according to the preset CAN communication node sequence is obtained.

[0079] Step S205: According to the communication system configuration parameter backup table, the original configuration data table arranged according to the preset CAN communication node sequence is obtained.

[0080] It should be noted that after the CAN nodes participating in the configuration update are obtained in the foregoing steps, the node update table can be constructed according to certain node ordering rules. Generally, if it is convenient for manual retrieval or checking, the node update table is sorted according to the identifiers or IDs of the nodes, which are usually in alphabetical order or numerical order. If it is for the convenience of rapid processing, the node update table is usually sorted according to the number of configuration change items, and the nodes with small update amounts are arranged in the front to facilitate the rapid use of part of the nodes.

[0081] It can be understood that the filter frame configuration data or the locally backed up configuration parameter table arranged according to the preset CAN communication node sequence can obtain a configuration parameter list arranged according to the logical or physical order of the CAN communication nodes, which is convenient for management and reference.

[0082] Step S206: The to-be-updated configuration data table and the original configuration data table are compared to obtain the communication filter frame configuration update content.

[0083] It should be noted that the configuration difference can be determined by comparing the new and old configuration data tables, for example, the same node may appear message information coverage, message information addition and deletion, and even part of the node is enabled or suspended. The update content can be accurately determined by the configuration difference, and the node and single rule change can be located.

[0084] It can be understood that in the embodiment, the comparison process is completely automated, and there is no human error, and the processing efficiency is high.

[0085] Step S207: The communication filter frame configuration update content is converted into the MCAL format, and the converted MCAL file is taken as the communication configuration update information.

[0086] It can be understood that the configuration update content obtained by comparison is converted into the MCAL (Microcontroller Abstraction Layer) format. The conversion process can accurately map the configuration in the comparison result to the structure of the MCAL file through a pre-established MCAL file template.

[0087] It should be understood that the MCAL format is designed for software components independent of specific microcontrollers, enabling software to run on different hardware platforms without modification. The generated MCAL file directly overwrites the configuration file path of the vehicle communication system as communication configuration update information, simplifying the processing flow and improving configuration update efficiency.

[0088] The embodiment provides a vehicle communication parameter configuration method. The embodiment realizes configuration update of a vehicle communication system through an automated process. First, a DBC parsing script is used to identify and record CAN communication node identifiers and message frame definition information. Then, filter frame configuration data is generated based on this information, and a configuration data table to be updated is constructed. Next, the configuration data table to be updated is compared with a backup original configuration data table to identify configuration differences that need to be updated. Finally, these differences are converted into MCAL format and directly overwritten into the configuration file path of the vehicle communication system to complete automated update. The entire process not only improves configuration update efficiency and accuracy, but also ensures cross-platform compatibility and system stability through standardized MCAL format.

[0089] In summary, the method brings a series of significant benefits by automatically parsing DBC files and updating vehicle communication parameters. First, the scheme greatly improves the speed and accuracy of configuration update, ensuring that the configuration of each node in the CAN network quickly and accurately reflects the latest communication requirements. Second, the automated process reduces human error and reduces the risk of system failure caused by improper manual configuration, thereby enhancing the stability and reliability of the entire vehicle communication system. In addition, by converting configuration update content into standardized MCAL format, cross-platform deployment and maintenance work is simplified. The automated test step further ensures the performance and security of the updated system, reducing on-site debugging and problem solving time. Ultimately, this scheme not only optimizes the maintenance process of the vehicle communication system and reduces long-term operating costs, but also supports continuous innovation and development of automotive technology by providing a more flexible and responsive update mechanism.
