If the number of CAN routing information is greater than or equal to the second set threshold, it indicates that the number of CAN routing information is large and the CAN routing information is not missing, that is, the CAN routing information is complete. On the contrary, if the number of CAN routing information is less than the second set threshold, it indicates that the number of CAN routing information is small and the CAN routing information is missing, that is, the CAN routing information is not complete.

[0055] The second setting character is used to indicate that the CAN routing information has integrity. There are no excessive restrictions on the second setting character, for example, the second setting character can be "#", "&", "xxx", etc.

[0056] The second preset format refers to the preset format specification of the CAN routing information.

[0058] S106, configuring the CAN message information according to the CAN routing information, and obtaining a second DBC file after the first DBC file is updated.

[0059] In the embodiment of the present disclosure, the CAN message information is configured according to the CAN routing information to obtain the second DBC file after the first DBC file is updated. The following possible implementation methods can be adopted:

[0060] Method 1: Match the first field name of the CAN routing information and the second field name of the CAN message information. When the first field name and the second field name match, configure the CAN message information according to the CAN routing information.

[0061] It should be noted that there are no excessive restrictions on the first field name and the second field name. For example, the first field name may include the message name, message identifier, message identifier format, message DLC, message sending type, message cycle time, message sender, etc. The second field name may include the message name, message identifier, message routing category, message sender, message receiver, etc.

[0062] It should be noted that, when the first field name and the second field name match, the first field name and the second field name may be the same or different, and one first field name may match multiple second field names.

[0063] In one embodiment, the first field name of the CAN routing information and the second field name of the CAN message information are matched, including identifying that there is a mapping relationship between the first field name and the second field name, and determining that the first field name and the second field name match, or identifying that there is no mapping relationship between the first field name and the second field name, and determining that the first field name and the second field name do not match.

[0064] For example, it can be identified that there is a mapping relationship between the first field name message name and the second field name message name, and it is determined that the first field name message name and the second field name message name match; it can be identified that there is no mapping relationship between the first field name message name and the second field name message receiver, and it is determined that the first field name message name and the second field name message receiver do not match.

[0065] In one embodiment, the first field name of the CAN routing information and the second field name of the CAN message information are matched, including identifying that the first field name and the second field name are consistent, determining that the first field name and the second field name match, or identifying that the first field name and the second field name are inconsistent, determining that the first field name and the second field name do not match.

[0066] For example, it can be identified that the message name of the first field name and the message name of the second field name are consistent, and it can be determined that the message name of the first field name and the message name of the second field name match, and it can be identified that the message name of the first field name and the message receiver of the second field name are inconsistent, and it can be determined that the message name of the first field name and the message receiver of the second field name do not match.

[0067] In one embodiment, the CAN message information is configured according to the CAN routing information, including configuring the CAN message information as CAN routing information, that is, configuring the field value corresponding to the second field name as the field value corresponding to the first field name, and / or determining the configuration content based on the CAN routing information, and configuring the CAN message information according to the configuration content.

[0068] For example, if the CAN routing information includes CAN nodes x and y, and the first field name of CAN nodes x and y is CAN node, and if the CAN message information includes CAN node y, and the second field name of CAN node y is CAN node, then it can be identified that the first field name and the second field name are consistent. Once it is determined that the first field name and the second field name match, the CAN node y in the CAN message information can be modified to CAN nodes x and y.

[0069] Method 2: Match the first field name of the CAN routing information and the second field name of the CAN message information. If there is no second field name matching the first field name, generate CAN new message information according to the CAN routing information.

[0070] In one implementation, generating CAN new message information according to CAN routing information includes configuring the CAN new message information as CAN routing information, and / or determining configuration content based on the CAN routing information, and generating CAN new message information according to the configuration content.

[0071] In one implementation, the third field name of the CAN newly added message information is consistent with the first field name.

[0072] For example, if the CAN routing information includes CAN nodes x and y, the first field name of CAN nodes x and y is CAN node. If there is no second field name matching the CAN node, then according to CAN nodes x and y, CAN new message information of CAN nodes x and y can be generated, and the third field name of the CAN new message information is CAN node.

[0073] S107, determining that an abnormality occurs in the first DBC file.

[0074] S108, determining that an abnormality occurs in the PDU routing file.

[0075] In one embodiment, after determining that the first DBC file is abnormal, it also includes generating alarm information for reminding the user that the first DBC file is abnormal, so as to promptly remind the user that the first DBC file is abnormal. It should be noted that there are no excessive restrictions on the alarm information for reminding the user that the first DBC file is abnormal, for example, it may include the identifier of the first DBC file, DBC message information, the identifier of the DBC message information, etc.

[0076] In one embodiment, after determining that the PDU routing file is abnormal, it also includes generating an alarm message for reminding that the PDU routing file is abnormal, so as to promptly remind the user that the PDU routing file is abnormal. It should be noted that there is no excessive limitation on the alarm message for reminding that the PDU routing file is abnormal, for example, it may include the identifier of the PDU routing file, the PDU routing information, the identifier of the PDU routing information, etc.

[0077] In summary, according to the configuration method of the control local area network database DBC file of the embodiment of the present invention, information can be extracted from the first DBC file and the PDU routing file respectively to obtain CAN message information and CAN routing information, and based on the CAN message information and the first preset rule, it is automatically determined whether the first DBC file is abnormal, and based on the PDU routing information and the second preset rule, it is automatically determined whether the PDU routing file is abnormal, and after both the first DBC file and the PDU routing file are normal, the first DBC file is updated according to the CAN routing information, which can avoid updating the first DBC file when the first DBC file and the PDU routing file are abnormal, resulting in the problem of DBC file configuration errors, and helps to improve the configuration accuracy and efficiency of the DBC file.

[0078] Based on any of the above embodiments, after obtaining the second DBC file updated from the first DBC file in step S106, the method further includes importing the second DBC file into a conversion plug-in, and the conversion plug-in converts the second DBC file to obtain a first CAN configuration file.

[0079] It should be noted that the CAN configuration file refers to the description file used to generate the CAN code file. There is no excessive limitation on the CAN configuration file. For example, it may include the configuration files of Canif (Controller Area Network Interface Module) and PDUR (Protocol Data Unit Router Module). For example, the CAN configuration file may include ARXML (Automotive Open System Architecture Extensible Markup Language) files.

[0080] It should be noted that the conversion plug-in can be implemented using any software tool in the relevant technology, for example, it can include a Vector tool.

[0081] Therefore, in the method, the second DBC file can be converted by the conversion plug-in to obtain the first CAN configuration file, which can realize the automatic generation of the CAN configuration file and improve the generation efficiency of the CAN configuration file.

[0082] Based on any of the above embodiments, Figure 2 After obtaining the second DBC file updated from the first DBC file in step S106, the method further includes:

[0083] S201, importing the second DBC file into the conversion plug-in, and the conversion plug-in converts the second DBC file to obtain a first CAN configuration file.

[0084] For the relevant contents of step S201, please refer to the above embodiment, which will not be described again here.

[0085] S202: extract information from the first CAN configuration file to obtain CAN configuration information.

[0086] S203, configuring the CAN configuration information according to the CAN routing information, and obtaining a second CAN configuration file after the first CAN configuration file is updated.

[0087] It should be noted that the relevant content of step S207 can refer to the relevant content of step S104, which will not be repeated here.

[0088] It should be noted that there are no excessive restrictions on the third field name. For example, the third field name may include message name, message identifier, message identifier format, message DLC, message sending type, message cycle time, message sender, etc.

[0089] In one implementation, the CAN configuration information is configured according to the CAN routing information, including matching the first field name of the CAN routing information and the third field name of the CAN configuration information, and when the first field name and the third field name match, the CAN configuration information is configured according to the CAN routing information. It should be noted that the relevant content of matching the first field name and the third field name can refer to the relevant content of matching the first field name and the second field name in the above embodiment, which will not be repeated here.

[0090] In one embodiment, after obtaining the second CAN configuration file updated from the first CAN configuration file, the method further includes importing the second CAN configuration file into a conversion plug-in, and converting the second CAN configuration file by the conversion plug-in to obtain a CAN code file. Thus, in the method, the second CAN configuration file can be converted by the conversion plug-in to obtain a CAN code file, and the automatic generation of the CAN code file can be realized, thereby improving the generation efficiency of the CAN configuration file.

[0091] In one implementation, after obtaining the second CAN configuration file that is updated from the first CAN configuration file, the method further includes storing the second CAN configuration file in a set storage space to implement storage of the second CAN configuration file.

[0092] Therefore, in the method, the second DBC file is imported into the conversion plug-in, and the conversion plug-in converts the second DBC file to obtain the first CAN configuration file, extracts information from the first CAN configuration file to obtain CAN configuration information, and configures the CAN configuration information according to the CAN routing information to obtain the second CAN configuration file after the first CAN configuration file is updated. Therefore, the information of the first CAN configuration file can be extracted to obtain the CAN configuration information, and the CAN configuration information can be configured according to the CAN routing information to update the first CAN configuration file, and the automatic configuration of the CAN configuration file can be realized according to the PDU routing file, thereby improving the configuration efficiency of the CAN configuration file.

[0093] In order to implement the above embodiment, the present disclosure also proposes a configuration device for controlling a local area network database DBC file.
