Below in conjunction with accompanying drawing, describe according to the automatic generation method of the OBD variable-definition source file of the embodiment of the present invention.
As shown in Figure 1, the automatic generation method according to the OBD variable-definition source file of the embodiment of the present invention, comprises the following steps:
Step S101, obtains a plurality of OBD variablees, and wherein, each OBD variable comprises name variable and a plurality of attribute field.
Step S102, writes a plurality of OBD variablees in default file.Wherein, default file is a pre-set csv file.In one embodiment of the invention, the content format example of default file is as shown in table 1:
Table 1
The OBD variable of default file comprise name variable and a plurality of attribute field as shown in table 2:
| Content | Sequence number | Content | Sequence number |
| Column_ID | 0 | Column_FF_Priority | 10 |
| Column_Fault_Name | 1 | Column_MIL1_Behaviour | 11 |
| Column_AFL_Threshold | 2 | Column_MIL2_Behaviour | 12 |

Table 4
In table 4, const uint8_t represents the form of variable, as title and the attribute field thereof of the expression variablees such as A_SENS_SUPPLY_FAULT_afl_threshold, A_SENS_SUPPLY_FAULT_afl_increment, A_SENS_SUPPLY_FAULT_warning_mask and A_SENS_SUPPLY_FAULT_eobd_fault, 50u, 10u, 1u and FALSE etc. represent the content of the attribute field that variable is corresponding.For example, the first row of table 4 represents that name variable is A_SENS_SUPPLY_FAULT_, and attribute field is afl_threshold, and the content that attribute field is corresponding is 50u.
The generation of obd_table.h source file further comprises: the Fault_Name field of first obtaining OBD variable in default file, and write in the 3rd array (obd_table array) according to name variable generation table related content, finally according to the 3rd array, generate obd_table.h source file.In one embodiment of the invention, table related content is as shown in table 5 below:
Table 5
The generation of obd_data.h source file further comprises: the Fault_Name field of obtaining the OBD variable in default file, and write in the 4th array (obd_data array) according to name variable generation data related content, according to the 4th array, generate obd_data.h source file.Wherein, data related content is as shown in table 6 below:
Table 6
The generation of obd_config.h source file further comprises: first according to the Fault_Name field of obtaining OBD variable in default file, and write in the 5th array (obd_config array) according to name variable generation config related content, according to the 5th array, generate obd_config.h source file.
The generation of obd.a2l source file further comprises: the Fault_Name field of first obtaining the OBD variable in default file, and write in the 6th array (obd.a2l array) according to name variable generation a2l related content, finally according to the 6th array, generate obd.a2l source file.
Further, in above-mentioned example, during end identifier in reading default file, stop reading, and stop continuing to generate OBD variable-definition source file.Wherein, finishing indications is preset by technician.
As concrete example, below in conjunction with Fig. 2-9, describe in detail according to the automatic generation method of the ODB variable-definition source file of the embodiment of the present invention.
Fig. 2 is the overall work schematic diagram of the automatic generation method of OBD variable-definition source file according to an embodiment of the invention.
As shown in Figure 2, what OBD variable was correlated with is content-defined in a csv file (being default file), i.e. Fault_Definitions.csv file in figure, then pass through perl pin language automatically by a series of operations such as the variable-definition process sequence in this csv file, inspection, extraction, changes, generate a plurality of source files of relevant obd module variable-definition, i.e. obd_const.h source file in Fig. 2, obd_data.h source file, obd_table.h source file, obd_externals.h source file, obd_config.h source file and obd.a2l source file.Wherein, perl script is a kind of language that is applicable to very much editor and processes various texts, replaces the work of human-edited and modification by the mode of carrying out perl script, can simplify widely work, raises the efficiency and quality, reduces cost of development.

Step S911, $ a2l_str=get_odb_a2l_trailer.Generate the ending of a2l file and write in variable $ a2l_str.
Step S912, is written to the content of $ a2l_str in@OBD_A2L array.
Step S913, End.Be that workflow finishes.
In above-mentioned example, the major function of sort_io_spec function for sorting is; The major function of create_obd_const_data function is to generate OBD_CONST, OBD_DATA, OBD_TABLES, tetra-arrays of OBD_EXTERNALS; The major function of create_obd_config function is to generate@OBD_CONFIG array; The major function of create_obd_a2l function is to generate@OBD_A2L array.In above-mentioned example, utilize perl script to replace artificial treatment, by the variable-definition of various OBD modules in csv file, by perl script, automatically read csv file content, read content, according to required sequence, by required variablees of extraction such as the definition of each class variable, titles and modify, integrate, is finally exported to required Sources file, thereby improved development efficiency and accuracy rate, reduced cost of development simultaneously.
Automatic generation method according to the OBD variable-definition source file of the embodiment of the present invention, can generate the source code file that OBD module contents is relevant automatically by software, has saved human cost, shorten the construction cycle, improve development efficiency, also reduced error rate simultaneously, improved development quality.In addition, the embodiment of the present invention is applicable to different development platforms, after it can being revised a little, migrates in different development platforms and uses, and therefore also has advantages of that portability is high, universality is high.
