The communication module is an important component of this architecture. Currently, the communication module is developed and maintained in the BSW layer (Basic Software). Every change in communication interaction requires parsing the communication data in the communication data packet in the BSW layer, and then further upgrading and modifying the overall code (i.e. updating). However, parsing in the BSW layer requires manual code writing, which is inefficient. Summary of the invention

[0005] The above method extracts the communication data packets received by the BSW layer and decouples them to the ASW layer. In the ASW layer, an interactive interface can be used to configure the format information, and a parsing tool can be used to automatically generate parsing code for parsing, which is more efficient than parsing in the BSW layer.

[0006] In some embodiments of the present disclosure, extracting and decoupling communication data packets received by the BSW layer to the ASW layer includes: Extract the communication data packets received by the BSW layer; By establishing a fixed communication interface for decoupling, the communication data packet is transmitted to the ASW layer using the fixed communication interface.

[0007] The fixed communication interface can realize the soft decoupling of the communication data packets received by the BSW layer and the communication data packets parsed by the ASW layer. In subsequent updates, if the content of the received communication data packet changes, only the format configuration information and communication standard files need to be updated to complete the communication data update, which is simple and convenient.

[0025] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. It is obvious that the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0026] Unless otherwise specified, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0027] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] It should be noted that similar symbols and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it does not require further discussion in subsequent figures.

[0031] In order to solve the problems existing in parsing communication data in the BSW layer, the present disclosure proposes a communication data parsing method, an updating method and related devices, specifically placing the parsing process in the ASW layer, and improving the parsing efficiency with the help of existing parsing tools.

[0032] Figure 1 is a schematic diagram of an embodiment of the communication data parsing method disclosed in the present invention, Figure 1 The embodiments may be executed by a terminal (such as a computer).

[0033] like Figure 1 As shown, in step 1 of the embodiment, the communication data packet received by the BSW layer is extracted and decoupled to the ASW layer (Application Software Layer).

[0034] It should be noted that the BSW layer is the basic software layer, and its internal operations can only be performed by manually writing codes without the help of existing tools. Therefore, in order to improve efficiency, the parsing of communication data packets is migrated to the ASW layer, which facilitates some existing tools and improves efficiency.

[0035] In some embodiments, the communication data packet extraction and decoupling process may be as follows: Based on the communication data packets received by the BSW layer under the AutoSAR architecture, the communication data packets are decoupled from the communication module of the BSW layer by establishing a fixed communication interface, and the communication data packets are transmitted to the ASW layer through the fixed communication interface.

[0036] It should be noted that the fixed communication interface defines a fixed array variable A, and assigns the communication data packet received by the BSW layer in real time to the array variable A. When the ASW layer receives the communication data packet transmitted by the array variable A, it parses the communication data packet, releases the array variable A after parsing, and reassigns the newly received communication data packet.

[0037] The fixed communication interface can realize the soft decoupling of the communication data packets received by the BSW layer and the communication data packets parsed by the ASW layer. In subsequent updates, if the content of the received communication data packet changes, only the format configuration information and communication standard files need to be updated to complete the communication data update, which is simple and convenient.

[0038] return Figure 1 In step 2 of the embodiment, in the ASW layer, according to the format configuration information preset in the interactive interface, the communication data in the communication data packet is converted into a format that can be parsed by a preset parsing tool, and according to the communication standard file corresponding to the communication data packet, a preset parsing tool is used to parse the communication data packet after the converted format.

[0039] It should be noted that the interactive interface can adopt a GUI interface, through which some format configuration information can be manually input, that is, only data that meets this format configuration information can be parsed by the parsing tool. The specific format configuration information may include communication protocol mode, message length, message error frame (such as CAN message error frame), communication protocol bit rate switch (such as CAN FD bit rate switch), communication protocol error status indicator (such as CAN FD error status indicator), data length code value and message identifier (CAN message identifier), etc.; among them, the content of each element in the format configuration information (i.e., communication protocol mode, message length, message error frame, communication protocol bit rate switch, communication protocol error status indicator, data length code value and message identifier, etc.) can be flexibly configured (i.e., manually input), thereby improving the efficiency of communication data conversion.

[0040] At the ASW layer (Application Software Layer), data analysis can be done directly using existing analysis tools, specifically visual simulation tools such as Simulink, which is a mature tool with the advantages of wide adaptability, clear structure and process, fine simulation, close to reality, high efficiency and flexibility.

[0041] Taking Simulink as an example, in order to adapt the tool, it is necessary to convert the data in the communication data packet into a format that can be parsed by Simulink according to the format configuration information.

[0042] Specifically, a structure data type canFDMessageBusType can be defined. The structure data can be parsed by the data packet module CANFD_Unpack of simulink, and the extracted data packet interface data is transferred to the Data element of canFDMessageBusType. The above format configuration information and Data data constitute a canFDMessageBusType structure data type data.

[0043] In some embodiments, the process of parsing the communication data packet after the format conversion can be: importing the communication standard file corresponding to the communication data packet into the visual simulation tool, and using the visual simulation tool imported with the communication standard file to parse the communication data packet after the format conversion. Using a mature visual simulation tool combined with the communication standard file to parse the communication data packet saves the time of generating the parsing code and improves the parsing efficiency.

[0044] Taking simulink as an example, the data packet module CANFD_Unpack is used in simulink to perform graphical analysis of data. Specifically, the communication standard file can be imported into simulink first, that is, import CANFD_Unpack. The communication standard file (DBC file) is a file format used to define the CAN bus communication protocol. It is mainly used to describe the signals, messages, nodes and other information in the CAN bus network. Specifically, it is a standard file that describes CAN communication information. The data that needs to be parsed in the package is determined through the DBC file, and then the data packet is parsed.

[0045] In order to improve efficiency, a GUI interface can also be used to import communication standard files and select corresponding parsed signals in DBC files.

[0046] It should be noted that after the parsing of the data packet is completed, the parsing result can be further output through the output interface.

[0047] The above method extracts the communication data packets received by the BSW layer and decouples them to the ASW layer. In the ASW layer, an interactive interface can be used to configure the format information, and a parsing tool can be used to automatically generate parsing code for parsing, which is more efficient than parsing in the BSW layer.

[0050] The first parsing module of the embodiment is configured to, in the ASW layer, convert the communication data in the communication data packet into a format that can be parsed by a preset parsing tool according to the format configuration information preset in the interactive interface, and parse the communication data packet after the converted format using a preset parsing tool according to the communication standard file corresponding to the communication data packet.

[0051] It should be noted that in the first parsing module, the preset parsing tool is a visual simulation tool; the parsing process of the communication data packet after the conversion may include: importing the communication standard file corresponding to the communication data packet into the visual simulation tool, and using the visual simulation tool that imports the communication standard file to parse the communication data packet after the conversion. Using a mature visual simulation tool combined with a communication standard file to parse the communication data packet saves the time of generating parsing code and improves the parsing efficiency.

[0052] Similar to the above method, the above device extracts the communication data packets received by the BSW layer and decouples them to the ASW layer. In the ASW layer, an interactive interface can be used to configure the format information, and a parsing tool can be used to automatically generate parsing code for parsing, which is more efficient than parsing in the BSW layer.

[0054] like Figure 3 As shown, S1 of the embodiment adopts a communication data parsing method to parse a new communication data packet received by the BSW layer.

[0055] It should be noted that, during parsing, only the format configuration information and the communication standard file in the communication data parsing method need to be adjusted to obtain a new parsing result.

[0056] return Figure 3 , S2 of the embodiment, sends the parsing result of the new communication data packet to the BSW layer, and updates the parsing result of the old communication data packet in the BSW layer.

[0057] In the above method, communication data parsing is performed in the ASW layer. When the communication changes, only the format configuration information and the communication standard file need to be adjusted to obtain new parsing results, thereby improving the update efficiency.
