Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

The detailed description of the present application is further described in detail below with reference to the drawings and examples. The following examples are illustrative of the present application but are not intended to limit the scope of the values of the present application.

Example 1

Fig. 1 is a flow chart of a method for repairing a DBC file according to an embodiment of the present application, as shown in fig. 1, where the method includes:

s5, generating a target DBC file according to the DBC file to be repaired.

The DBC file is a text file, has higher definition freedom, can provide a larger custom space for users, and therefore, the same bus information and text content have larger difference, and the conventional text comparison tool cannot repair the DBC file. The method of the embodiment of the application can be applied to a DBC tool to repair DBC files.

Further, S2 includes:

acquiring attribute information of a plurality of initial DBC files;

comparing version serial numbers of a plurality of initial DBC files according to the attribute information to obtain a plurality of difference results;

and performing attribute detection on the multiple difference results to obtain multiple versions of difference data.

The attribute information comprises a message name, a message ID, a message sending mode and period, a signal name, a signal length and a signal starting position in the message. The two versions of attribute information are compared and shown in the following table:

In the implementation process, the message information and the signal information in the difference result are extracted, and the attribute detection is carried out on the message information and the signal information according to the detection items, so that the obtained version difference data is more accurate.

Alternatively, if the engineering project is concerned about some attributes, the application may automatically generate codes or models according to the project requirements, and if there is a problem with these attribute information, the codes or models will have bug, so attribute detection is required before use.

According to the embodiment of the application, the detection items and the repair items are set according to the DBC protocol standard and the enterprise standard, and the configuration attributes which do not meet the requirements of the items can be checked in a targeted mode.

Further, the step of performing attribute detection on the message information and the signal information according to the detection item to obtain version difference data includes:

Optionally, the detecting content for detecting the attribute of the message information and the signal information includes: whether the message sending node is defined in the initial DBC file, whether the receiving or sending node is the controller node, whether the maximum and minimum values of the signals are within the allowed range defined by the data length, the precision, the offset and the like, and whether the initial values of the signals are within the allowed range.

After knowing the specific message name and node information, specific version difference data can be obtained, for example, the sending node of the A message is illegal, the receiving node of the B message is illegal, the C message is irrelevant to the controller node, the definition range of the A signal of the D message is unreasonable, and the initial value of the B signal of the E message is out of range.

When detecting the initial DBC file, prompting that the Max value of the VCU_NMDataField2 signal of the message with the ID of 0x5E3 exceeds the maximum range allowed by theory; the following message of 0x179 is illegal.

By using the automatic repair function, the problem that the 0x179 message receiving node is incorrect is selectively repaired, the repaired DBC is checked again, and the problem that the signal receiving node below the 0x179 message is illegal is solved.

In S3, according to the errors of the identified messages and signals, the messages and signals can be prompted to be confirmed and then modified, the DBC processing tool can be used for automatic repair, the DBC processing tool is used for checking again after the repair is finished, and the messages and signals of the DBC are ensured to be free of problems through repeated iteration.

Further, S4 includes:

constructing a DBC tool template;

and integrating the plurality of cut primary repair DBC files to obtain the DBC file to be repaired.

The template defined in the DBC tool of the embodiment of the application cuts the primary repair DBC file.

Optionally, in order to facilitate analysis or data collection of the experiment bench, the DBC files of different controller nodes need to be combined into a file, so that loading of an upper computer of the bench is facilitated, the integration processing is not simple physical integration, when an incompatible condition of attribute definition is met, the DBC files cannot be simply combined together, the difference between the primarily repaired DBC files needs to be identified, the two versions of the primarily repaired DBC files are fused to obtain a total DBC file, all messages, signals and attributes of the white willow are fused, and the incompatible attributes are fused into a universal form.

Further, the step of clipping the preliminary repair DBC file according to the DBC tool template to obtain a clipped preliminary repair DBC file includes:

acquiring project requirements;

selecting effective signals in a plurality of primary repair DBC files according to project requirements;

and cutting signals except for effective signals and attributes thereof in the plurality of primary repair DBC files according to the DBC tool template to obtain a plurality of cut primary repair DBC files.

According to project requirements (for example, a third party organization needs to be subjected to outsourcing test), useful signals (effective signals) need to be reserved in the clipping process, the reserved messages and the attributes of the signals cannot be lost, and all the messages and the signals except the effective signals and the attributes thereof are clipped.

Further, S5 includes:

and converting the DBC file to be repaired to obtain a formatted file containing the standard definition of the controller area network bus, and determining the formatted file containing the standard definition of the controller area network bus as a target DBC file.
