[0049] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0050] The following is an introduction to the terms involved in the embodiments of this application.

[0051] A2L file: A descriptive file for calibration, so called because the file name ends in .a2l. During the development of a vehicle calibration system, the calibration software (also called host computer software) in the vehicle calibration system is required to observe and calibrate the data in the vehicle's Electronic Control Unit (ECU). The observed and calibrated data is usually stored in an A2L file. The calibration software parses the A2L file using CCP (CAN Calibration Protocol, a calibration protocol based on the CAN bus) or XCP (Universal Calibration Protocol), enabling observation and calibration of ECU data.

[0052] Based on the different layers of ECU software, A2L files can be divided into application layer A2L files, interface layer A2L files, and bottom layer A2L files. In terms of file content, A2L files include device parameter information, interface data information, and ECU parameter information. Device parameter information describes the basic information of the ECU and the common attributes of the ECU data unit; interface data information describes the interface information required for communication between the calibration system and the ECU; and ECU parameter information describes the detailed contents of the ECU's internal data units.

[0053] ASAP (the Working Group for the Standardization of Application Systems) 2 standard: This standard specifies the description specifications for ECU internal data units. Therefore, the ASAP 2 standard is expressed in the A2L file.

[0054] The Electronic Control Unit (ECU), also known as the vehicle's "on-board computer," controls the vehicle's driving state and various functions. It operates by collecting and exchanging data via sensors and buses, determining the vehicle's status, and controlling actuators to control the vehicle.

[0055] Calibration: Based on the performance requirements of the ECU, the parameters in the ECU are modified online through the calibration software to achieve the purpose of optimizing the ECU performance.

[0056] Observation: Observe the impact of different parameters on the ECU operating status, assist in the calibration process, and optimize ECU performance.

[0057] This application embodiment provides a file synthesis method, please refer to Figure 1 , which shows a schematic diagram of an implementation environment of the method provided in an embodiment of the present application. The implementation environment may include: a terminal 11 and a server 12.

[0058] When a file needs to be synthesized, the terminal 11 can use the method provided in the embodiment of the present application to perform the synthesis. In addition, the server 12 can store the files to be synthesized, and the terminal 11 can obtain the files to be synthesized from the server 12 and then perform the synthesis operation on the files. Of course, the terminal 11 can also store the files to be synthesized.

[0059] Optionally, the terminal 11 can be any electronic product that can interact with the user through one or more methods such as a keyboard, touchpad, touch screen, remote control, voice interaction or handwriting device, such as a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart car computer, a smart TV, a smart speaker, etc. The server 12 can be a single server, a server cluster consisting of multiple servers, or a cloud computing service center. The terminal 11 establishes a communication connection with the server 12 via a wired or wireless network.

[0060] Those skilled in the art should understand that the above-mentioned terminal 11 and server 12 are only examples. Other existing or future terminals or servers that are applicable to this application should also be included in the scope of protection of this application and are included here by reference.

[0061] The present application embodiment provides a file synthesis method which can be applied to the above Figure 1 The implementation environment shown in Figure 1 is as follows. Figure 2 As shown, taking the method applied to a terminal as an example, the method includes the following steps 201 to 204.

[0062] In step 201, a first file and multiple second files are obtained, the first file includes an identifier of a first variable and a first address corresponding to the identifier of the first variable, the first address is located in the first address segment of the first file, any second file includes an identifier of a second variable and a second address corresponding to the identifier of the second variable, the identifier of the first variable contains the identifier of the second variable, and different variables have different identifiers.

[0063] In an exemplary embodiment, the first file can be generated by a compiler and saved in the .adx format. Typically, the number of first files is 1. The first file stores the identifier of the first variable and the first address corresponding to the identifier of the first variable. The identifier of the first variable can be the ID (Identity Document) of the first variable or the name of the first variable, which is not limited in the embodiment of the present application. One first variable corresponds to one identifier. If the first variables are different, the identifiers are also different.

[0064] In addition, the second file may be an A2L file. In one possible implementation, the second file includes at least one of an application layer file, an interface layer file, and a bottom layer file. This application does not limit the number of application layer A2L files, interface layer A2L files, and bottom layer A2L files. Typically, the number of application layer files is one, the number of bottom layer files is one, and the number of interface layer files may be one or more, such as three. Optionally, the second file may include one application layer file, one bottom layer file, and three interface layer files.

[0065] The embodiment of the present application does not limit the method for generating the second file. For example, the default configuration of Matlab / Simulink software (a computer simulation software) can be used for compilation to generate the electronic control unit embedded C code and the corresponding multiple second files. Because the software default configuration is used for compilation, the generated second file contains the initial address of the second variable. For example, the initial address of the second variable can be 0x0000.

[0066] Furthermore, the identifier of the first variable includes the identifier of the second variable, that is, the first variable includes the second variable. In an exemplary embodiment, the first variable and the second variable may be completely identical or not completely identical. For example, if the first variable is completely identical to the second variable, it means that the first variable is equivalent to the union of the multiple second variables included in the multiple second files; if the first variable and the second variable are not completely identical, it means that the first variable may include other variables in addition to the union of the multiple second variables.

[0067] Regardless of the above-mentioned relationship between the first variable and the second variable, the second variable in any second file exists in the first variable of the first file and does not affect the implementation of the method provided in the embodiment of the present application.

[0068] In step 202 , based on the identifiers of the second variables in the respective second files, a first address corresponding to the identifier is searched in the first address section.

[0069] For example, if the identifier of any second variable in any second file is *a, since the identifier of the first variable includes the identifier of the second variable, the first address corresponding to the identifier *a will exist in the first address segment in the first file.

[0070] Taking the development of a vehicle calibration system as an example, as an example, the process typically involves two variables: a calibration variable and an observation variable. In this case, the first variable can be divided into a first calibration variable and a first observation variable based on variable type. Similarly, the second variable can be divided into a second calibration variable and a second observation variable.

[0071] In an exemplary embodiment, the first calibration variable and the first observation variable are stored in different storage media. For example, the storage media for the first calibration variable may be a Flash memory (also known as flash memory), while the storage media for the first observation variable may be a RAM (Random Access Memory). Because the first calibration variable and the first observation variable are stored in different storage media, they are located in different address segments in the first file.

[0072] Based on the above content, exemplarily, the first calibration address corresponding to the identifier of the first calibration variable is located in the second address segment, the first observation address corresponding to the identifier of the first observation variable is located in the third address segment, and the first address segment includes the second address segment and the third address segment.

[0073] Therefore, in one possible implementation, based on the identifier of the second variable in each second file, the first address corresponding to the identifier is queried within the first address segment, including: based on the identifier of the second calibration variable in each second file, the first calibration address corresponding to the identifier is queried within the second address segment; based on the identifier of the second observation variable in each second file, the first observation address corresponding to the identifier is queried within the third address segment.

[0074] The query principle of the first calibration address and the first observation address is the same as the query principle of the first address mentioned above, and will not be repeated here. In addition, the embodiment of the present application does not limit the range of the second address segment and the third address segment, and can be flexibly set according to experience or actual application scenarios. For example, the second address segment can be 0x80340000-0x803FFFFF; the third address segment can be 0x60000000-0x6010BFFF.

[0075] In step 203 , the second address in each second file is replaced with the first address corresponding to the identifier of the second variable in each second file, thereby obtaining a plurality of third files, where one second file corresponds to one third file.

[0076] For example, if the identifier of any second variable in any second file is *a, and the first address corresponding to the identifier *a is 0x80340000 and the second address corresponding to the identifier *a is 0x0000, then the second address 0x0000 is replaced with 0x80340000. By replacing the addresses of the second variables in each second file using the above method, multiple third files can be generated.

[0077] According to the contents of step 202, when the first variable includes the first calibration variable and the first observation variable, and the second variable includes the second calibration variable and the second observation variable, the second address includes the second calibration address and the second observation address. Replacing the second address in each second file with the first address corresponding to the identifier of the second variable in each second file to obtain multiple third files includes: replacing the second calibration address in each second file with the first calibration address corresponding to the identifier of the second calibration variable in each second file, and replacing the second observation address in each second file with the first observation address corresponding to the identifier of the second observation variable in each second file, to obtain multiple third files.

[0078] The replacement principle of the second calibration address and the second observation address is the same as the replacement principle of the second address mentioned above, and will not be repeated here.

[0079] In step 204, a plurality of third files are merged to obtain a target file.

[0080] For example, if the second file contains an application layer file, an interface layer file, and a bottom layer file, variables within the files at different layers may be interrelated. For example, if a calibration variable is used in both the application layer and the interface layer, it will appear repeatedly in both the application layer and the interface layer files. Given this, multiple third files generated by address replacement in multiple second files may contain duplicate variables. Therefore, duplicate variables need to be deduplicated.

[0081] In one possible implementation, a plurality of third files are merged to obtain a target file, including: traversing each third file, deduplicating second variables with the same identifier, where the second variables with the same identifier are located in different third files; and merging the plurality of third files that have undergone deduplication to obtain the target file.

[0082] like Figure 3 As shown, the method of traversing each third file and performing deduplication processing on the second variables with the same identifier includes the following steps 2041 to 2042.

[0083] Step 2041: Divide the plurality of third files into a plurality of file pairs, where each file pair includes two third files.

[0084] Dividing the plurality of third files into a plurality of file pairs refers to combining the plurality of third files in pairs. For example, if there are four third files A, B, C, and D, then a total of six file pairs can be divided, namely, file pairs (A, B), (A, C), (A, D), (B, C), (B, D), and (C, D).

[0085] Step 2042: For any file pair, if the identifier of the second variable in one third file is the same as the identifier of the second variable in another third file, delete any one of the second variable in one third file and the second variable in another third file.

[0086] For example, if the identifier of any second variable in the third file A is searched, it is necessary to determine whether the identifier of any second variable exists in the third file B, the third file C, and the third file D. Taking the above-mentioned file pair (A, B) as an example, if the identifier of the second variable a in the third file A is the same as the identifier of the second variable b in the third file B, since different variables have different identifiers, it can be determined that the second variable a is the same as the second variable b. In this case, the second variable a in the third file A can be deleted, or the second variable b in the third file B can be deleted. The method for searching the identifier of the second variable a in the file pairs (A, C) and (A, D) is similar.

[0087] In the process of searching for a second variable a with the same identifier as above, you can use the regular expression r"\s+ / \*\s+Name\s+\* / " to match the identifier of the second variable a. This method can quickly find variables with the same identifier with high accuracy.

[0088] After obtaining multiple third files that have undergone deduplication processing, the multiple third files are merged to obtain the target file. Figure 4 As shown, this step may include the following steps 2043 to 2044.

[0089] Step 2043: Merge the multiple third files that have undergone deduplication processing to obtain an initial target file.

[0090] Any third file includes multiple different file blocks such as HEADER, MODULE, AXIS_PTS, CHARACTERISTIC, MEASUREMENT, COMPU_METHOD, GROUP, etc.

[0091] Among them, HEADER is used to describe project information, such as project number, project version, etc. A third file corresponds to a project. MODULE contains all relevant information of ECU, such as memory allocation of ECU, etc. CHARACTERISTIC is used to define calibration variables, including the name and address of calibration variables. AXIS_PTS is used to define the type of axis corresponding to the variable. For example, when the calibration variable requires multiple axes (X, Y) to determine, AXIS_PTS is needed to define one of the axes. MEASUREMENT is used to define observation variables, including the name and address of the observation variable. COMPU_METHOD is used to define calculation formulas, which can be referenced by calibration variables and observation variables. GROUP is used to combine calibration variables and observation variables according to a certain logic, forming a drop-down menu in the calibration software, so that users can select variables from it.

[0092] Therefore, when performing a merging operation on multiple third files, it is sufficient to merge multiple file blocks of each third file to obtain an initial target file.

[0093] Step 2044: Delete the comment statements in the initial target file to obtain the target file.

[0094] After obtaining the initial target file, you can delete the comment statements in the initial target file. This operation can also be called initializing the initial target file. After deleting the comment statements, the number of target files obtained is 1.

[0095] In an exemplary embodiment, a regular expression can be used to delete comment statements in a file. For example, in an A2L file, / ** / represents a comment statement. For the string ' / *ECU Address* / 0x0000 / *@ECU_Address@TCM_stTraShiftInProgress_E@* / ' that can reflect the variable address, ' / *ECU Address* / ' and ' / *@ECU_Address@TCM_stTraShiftInProgress_E@* / ' are comment statements. If you need to delete ' / *ECU Address* / ' and ' / *@ECU_Address@TCM_stTraShiftInProgress_E@* / ' in the string and retain the '0x0000' substring in the string, you can use the regular matching expression "\s+ / \*.*?\* / ". This expression can quickly delete comment statements in a string by performing greedy matching and returning as few matches as possible.

[0096] Figure 5 Schematic diagram of the file synthesis method. Figure 5 In the example, the application layer file in 501 is automatically generated based on the Matlab / Simulink automatic code tool; the interface layer file is independently developed by the user; the bottom layer file is delivered as a black box by the supplier; 502 is a burnable file, which is the machine code file obtained by the compiler after the application layer, interface layer and bottom layer source code are compiled and linked. This file contains the actual addresses of all application layer, interface layer and bottom layer variables. After replacing the variable addresses in multiple A2L files with the actual addresses of the corresponding variables in the burnable files, the function recursive method in 503 is used to traverse multiple A2L files, and then the identifiers of the variables in multiple A2L files are matched using regular matching expressions, and the identifiers of the same variables are searched for duplicates and duplicate operations are removed. Then, multiple A2L files are merged, and the comment statements in the merged files are deleted using the greedy matching method, and the target file 504 is finally obtained.

[0097] In an embodiment of the present application, the first file includes an identifier for a first variable and a first address corresponding to the identifier, and the first address is located in the first address segment; the second file includes an identifier for a second variable and a second address corresponding to the identifier. Because the identifier of the first variable contains the identifier of the second variable, and the first address is located in the first address segment, the first address corresponding to the identifier of the second variable in each second file can be queried through the first address segment. This method shortens the query time for the first address and has high query efficiency. Due to the shortened query time, the time cost of subsequently merging multiple files to obtain the target file is also reduced.

[0108] In a possible implementation, the second file includes at least one of an application layer file, an interface layer file, and a bottom layer file.

[0109] In an embodiment of the present application, the first file includes an identifier for a first variable and a first address corresponding to the identifier, and the first address is located in the first address segment; the second file includes an identifier for a second variable and a second address corresponding to the identifier. Because the identifier of the first variable includes the identifier of the second variable, and the first address is located in the first address segment, the first address corresponding to the identifier of the second variable in each second file can be queried through the first address segment. This device shortens the query time for the first address and has high query efficiency. Due to the shortened query time, the time cost of subsequently merging multiple files to obtain the target file is also reduced.
