[0044] 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.

[0045] 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.

[0046] As the degree of automotive electronics continues to increase, the number and types of automotive electronic control units (ECUs) have increased dramatically, causing the signal network of the entire system to become extremely complex. In AUTOSAR (Automotive Open System Architecture), BSW (Basic Software) is a key component that provides the necessary underlying support and services for upper-level application software, including the key technology of signal mapping. Signal mapping is an important means of connecting different ECUs or signal transmission between modules within an ECU.

[0047] Existing signal mapping methods often rely on developers to manually configure the interface information in the DBC (Database CAN) file to generate relevant codes. However, this method has many shortcomings: first, the manual configuration process is cumbersome and technically demanding, requiring developers to have a deep understanding of the CAN protocol and specific hardware; second, manual configuration increases the possibility of errors, especially when the amount of data is large or the development time is tight; third, frequent manual adjustments and maintenance are required during system iteration and upgrade, which increases maintenance costs and workload; in addition, manual configuration also limits the improvement of development efficiency. Whenever a signal is added or modified in the DBC file, the filtering rules need to be reconfigured, which is not only time-consuming, but may also lead to inconsistent configurations, affecting the communication efficiency and reliability of the system. Therefore, a more efficient and accurate signal mapping configuration method is urgently needed to solve the problem of low signal mapping configuration efficiency.

[0048] The present application parses the data information in the DBC file through a script file and performs automatic mapping accordingly, thereby realizing automatic updating of the configuration file, solving the problem of low efficiency of signal mapping configuration, and improving the efficiency and quality of signal mapping configuration.

[0049] It should be noted that the execution subject of this embodiment can be an automatic configuration system for signal mapping, or 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 automatic configuration function of the above-mentioned signal mapping, etc., and this embodiment does not specifically limit this. The following takes the automatic configuration system for signal mapping as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the embodiment of the present application provides a method for automatically configuring signal mapping, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the automatic configuration method of signal mapping of the present application.

[0051] In this embodiment, the automatic configuration method of the signal mapping includes steps S10 to S30:

[0052] Step S10: Obtain the first script file, the second script file and the DBC file.

[0053] It should be noted that the DBC file is a standardized file format used to describe CAN bus communication data in a car network. The first script file and the second script file are Python scripts, and the system accesses and reads these files through the file system API. Specifically, in this step, the system first obtains two Python script files (i.e., the first script file and the second script file) and a DBC file from the project directory or the specified path. The first script file is used to "parse the DBC file script", and the second script file is used to "generate the ARXML file script". They are the core tools for realizing automated signal mapping. The DBC file contains all the signal definitions and message information required for communication between ECUs.

[0054] Step S20: Process the DBC file according to the first script file and the second script file to obtain a configuration file.

[0055] It should be noted that in this step, the first script is responsible for parsing the DBC file, extracting the message information and signal definition, and generating an intermediate text file (or directly processing it in memory). The second script calls the result of the first script and automatically generates a configuration file that complies with the AUTOSAR architecture based on the extracted information. In addition, it should be noted that in this step, the configuration file is an ARXML type file, that is, an XML format file used in the AUTOSAR standard to describe system configuration, software components and their interfaces.

[0056] In a feasible implementation manner, after step S20, the method further includes:

[0057] Step A10: Obtain the permission configuration file.

[0058] It should be noted that the system will obtain a pre-defined permission profile, which specifies in detail the access rights of different users or user groups to the configuration files. These rights include reading, modifying, deleting, etc. It can be understood that the permission profile is a file used to define and manage the access rights of users or user groups to system resources (such as configuration files), which can protect system security and prevent unauthorized access.

[0059] Step A20: Allocate access rights to the configuration file according to the authority configuration file.

[0060] It should be noted that in this step, the system will read the provisions in the permission configuration file and identify the access rights of different users or user groups to the configuration file. And based on the permission information read, the system will assign access rights to the configuration file (ARXML file). Only users with modification permissions can modify the configuration file. When a user tries to access the configuration file, the system will perform permission verification to ensure that the user's operation complies with their permission settings. For example, during the development process, when a member of the R&D team tries to modify the ARXML file, the system will check the records in its permission configuration file. If the member has modification permissions, he will be allowed to make the modification; otherwise, his request will be rejected and the prompt will indicate that he has no permission.

[0061] Step S30: updating the original configuration file according to the configuration file to complete the automatic configuration update of the signal mapping.

[0062] It should be noted that in this step, when the system generates an ARXML file containing the latest Signal Mapping configuration, the file will be overwritten to the corresponding location in the project directory to replace or update the original configuration file. Specifically, after the second script completes the generation of the ARXML file, the system will automatically detect whether there is an old ARXML file with the same name in the project directory. If the old file exists, the script will prompt the user whether to overwrite it and perform the overwrite operation according to the user's choice. After the overwrite operation is completed, the script will output a success message, indicating that the automatic configuration update of Signal Mapping has been completed.

[0063] It is understandable that in actual applications, updating configuration files also needs to consider strategies such as version control and backup to ensure the stability and traceability of the system.

[0064] In a feasible implementation manner, the step S30 specifically includes:

[0065] Step S301: Compare the configuration file with the original configuration file to obtain new information or deleted information.

[0066] It should be noted that the original configuration file refers to the configuration file that already exists in the current system and is used to describe the signal mapping relationship. It is also the basis for this automatic configuration update. New information refers to information such as signals, interfaces, or ports that appear in the newly generated ARXML file but do not exist in the original configuration file. Deleted information refers to information such as signals, interfaces, or ports that exist in the original configuration file but are no longer needed in the newly generated ARXML file.

[0067] Specifically, in this step, the system will compare and analyze the newly generated ARXML file with the original configuration file. This process includes but is not limited to checking key information such as signal names, interface definitions, and port configurations to identify which are newly added signals or interfaces (new information) and which signals or interfaces no longer exist in the original configuration file (deleted information).

[0068] It can be understood that this step is intended to ensure that the newly generated ARXML file (configuration file) can be seamlessly integrated with the original configuration file, thereby achieving automatic update of signal mapping.

[0069] Step S302: Update the original configuration file according to the newly added information or the deleted information.

[0070] It should be noted that in this step, the system will perform corresponding update operations on the original configuration file according to the new information and deleted information identified in step S301. The update operation includes different types of operations such as adding, modifying, and deleting, depending on the specific content of the new information and deleted information. For new information, the system will add these new signal, interface or port configuration information to the original configuration file; for deleted information, the system will remove these no longer needed configuration information from the original configuration file. It can be understood that this process ensures the synchronization and consistency between the original configuration file and the newly generated ARXML file.

[0071] The present embodiment provides an automatic configuration method for signal mapping, and the method of the present embodiment includes: obtaining a first script file, a second script file, and a DBC file; processing the DBC file according to the first script file and the second script file to obtain a configuration file; and updating the original configuration file according to the configuration file to complete the automatic configuration update of the signal mapping. In summary, the present embodiment parses the data information in the DBC file through the script file and performs automatic mapping based on it, thereby realizing the automatic update of the configuration file, solving the problem of low efficiency of signal mapping configuration, and improving the efficiency and quality of signal mapping configuration.

[0072] 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 , Figure 2 This is a flow chart of the second embodiment of the automatic configuration method for signal mapping of the present application, wherein step S20 specifically includes:

[0073] Step S201: Parse the DBC file according to the first script file to obtain a text file.

[0074] It should be noted that in this step, the first script file is designed to parse the DBC file, which is a standard format for communication between automotive electronic control units (ECUs), and contains key information such as signals, messages, and network nodes. The script reads the DBC file and parses the message information therein. For example, assuming that there is a DBC file containing communication messages between multiple ECUs, the first script will traverse these messages, parse the detailed attributes of each message, and write this information to a text file in an easy-to-process format. It is understandable that this can convert the complex DBC file content into a more concise and easier to operate text format, thereby improving the efficiency of subsequent automated configuration.

[0075] In a feasible implementation manner, the step S201 specifically includes:

[0076] Step B10: Parse the DBC file according to the first script file to obtain message information.

[0077] It should be noted that in this step, the system will read various parts of the DBC file through the first script, such as BO_ (message definition), SG_ (signal definition) and other tags, and parse out the detailed information of the message.

[0078] Step B20: Obtain the message type, frame format, CAN identifier, mailbox index number, indication information and the controller identifier to which the mailbox belongs according to the message information.

[0079] It should be noted that in this step, the system will process the message information extracted from the DBC file. And through the definition of the message, identify the message type (such as FULL or BASIC), frame format (standard frame or extended frame), CAN identifier (CANID), mailbox index number (used to distinguish different messages under the same CAN ID), indication information (such as receive / send flag) and the controller identifier to which the message belongs. For example, for a certain message, the script will recognize that its type is FULL, the frame format is an extended frame, the CAN ID is 0x123, there is no specific mailbox index number (because it is a FULL type), the indication information is a send flag, and the message is sent by the ECU with a controller ID of 0x01.

[0080] In addition, it should be noted that FULL and BASIC are two common forms of message types in CAN networks. FULL means that one mailbox corresponds to one CAN ID, while BASIC means that one mailbox can correspond to a group of CAN IDs, which are distinguished by the mailbox index number. The frame format determines the structure of the CAN frame. The standard frame and the extended frame differ in the ID length.

[0081] Step B30: The message type, the frame format, the CAN identifier, the mailbox index number, the indication information and the controller identifier to which the mailbox belongs are stored in a preset format to obtain a text file.

[0082] It should be noted that the preset format can be TXT format, or other formats with the same functions as TXT format files, and this embodiment does not limit this. Specifically, in this step, the system will store the message information extracted and processed in step B20 in a text file according to the preset format. The text file will be used as input for subsequent processing to generate an ARXML file that conforms to the AUTOSAR architecture. For example, all extracted information can be written to a text file in a comma-delimited format, with each line representing the information of a message, and fields separated by commas. The subsequent script can quickly read the file and generate a corresponding ARXML file based on the information therein.

[0083] Step S202: calling the first script file according to the second script file to extract information of the text file and generate a configuration file.

[0084] It should be noted that in this step, the second script file is designed to call the first script file, and based on the text file content generated by the first script, further process to generate an ARXML configuration file that complies with the AUTOSAR architecture. Specifically, the system calls the first script through the second script to ensure that the text file has been successfully generated and contains all necessary message information. Then, the second script reads the text file content and generates an ARXML configuration file, which contains all the necessary configuration information, such as the definition of the signal, the detailed information of the port and interface, and the mapping relationship between them.

[0085] In a feasible implementation manner, the step S202 specifically includes:

[0086] Step C10: Call the first script file according to the second script file to extract the information of the text file to obtain interface information, port information and signal name.

[0087] It should be noted that in this step, the system will extract key information of the text from the DBC file, including detailed data of the message, such as processing type (FULL or BASIC), frame format (standard frame or extended frame), CANID, index number of the mailbox object, and whether the message is received or sent, as well as the controller ID to which these messages belong. At the same time, the script will also obtain the interface requirement configuration pre-set by the developer, and based on the extracted message information, generate the basic information of the standard port and interface under the AUTOSAR architecture, such as the relevant data types and information of the SR interface or CS interface.

[0088] Step C20: Automatically map the signal name with the corresponding interface information and port information to obtain a configuration file.

[0089] It should be noted that in this step, the system will automatically perform the Signal Mapping operation using the extracted port, interface and signal name information through the second script file. This operation includes accurately matching the signal name with the matching interface information and port information, and generating an ARXML file that complies with the AUTOSAR architecture specification based on this information. Specifically, the script will search for corresponding matches in the previously generated port and interface information according to the signal name, and map the signal to the corresponding interface. In this process, the script will also automatically create the necessary XML tags and attributes to accurately describe the mapping relationship between the signal and the interface.

[0090] In this embodiment, by effectively combining two Python scripts, the automatic generation of ARXML configuration files from DBC files under the AUTOSAR architecture and the automatic configuration of Signal Mapping are realized, which reduces human intervention and potential errors and improves the stability and development efficiency of the system.

[0091] This application also provides an automatic configuration device for signal mapping, please refer to Figure 3 , the automatic configuration device of the signal mapping comprises:
