And step four, setting the control unit type attribute and the software attribute for the software of the control unit. Two attribute settings are made for the part number of the control unit: one is to select its corresponding control unit type, such as ESP (electronic stability program), AIC (audio control unit), BCM (body controller), etc.; and secondly, selecting which of the assembly, the software and the hardware is selected, and only the serial number of the software-type part can maintain a basic configuration table and a vehicle type configuration table in the subsequent steps and generate an EOL configuration code by analysis. In this embodiment, software of the sound control unit is selected as an example, and the control unit to which the sound control unit belongs is AIC and is a "software" class.
And step five, according to the related functions of the control unit, compiling a basic configuration table of the control unit software, namely setting the number of bytes for the control unit, wherein each byte comprises 8 bits, and each bit is composed of binary 0 and 1. Two or three bits may also be combined, represented by two binary values or three binary values. The two "values" 0 and 1 under each "bit" correspond to the presence and absence of a certain function, respectively, or represent two schemes of low-level and high-level of a class of functions, for example, 0 represents no skylight 1 for skylight 1 or 0 represents 6 speakers 1 for 8 speakers. If some two "bits" are used in combination, they can be combined into four "values": 00. 01, 10, 11, each value may correspond to a combination of a set of functions, for example: 00 denotes: no networking function & no remote function, 01 with networking function & no remote function, 10 with no networking function & with remote function, 11 with networking function & with remote function. In this embodiment, the AIC control unit software uses 3 bytes in total, and each byte has 8 bits, i.e., 24 bits in total. Some of the bits directly define the function of the value, and some adjacent bits are combined into two-bit values to define the function. The function defined by each bit or two bits per byte is given in table 4.
TABLE 4
And step six, compiling a vehicle type configuration table of the target vehicle system according to the functions related to the control unit. On the basis of the basic configuration table of the control unit, for each 'value' under each 'bit' under each 'byte', a corresponding characteristic value or a combination of characteristic values is compiled, and the association between the control unit and the characteristic values is established. As in the present example, see table 5: AT bit 5 of 1 byte, there are two values 0 and 1, 0 maintains its eigenvalue AT0, 2 maintains its eigenvalue AT1, and AT0 and AT1 represent the two eigenvalues: air cleaners (pollen/PM 2.5 filtration) and air cleaners (super cartridges).
TABLE 5
Analyzing and acquiring a binary configuration code of the control unit software on each single vehicle type in high-low configuration according to the engineering configuration table and the vehicle type configuration table by the system; table 6 is a list (binary) of parsed configuration codes;
in this embodiment, under three bytes of the AIC control unit software, each bit can resolve corresponding values under each single vehicle type (honor, flagship), for example, 1-0 bits of 2 bytes, the result of the honor type resolution is 01, the result of the honor type and flagship type resolution is 10, for example, 1 byte 5 bits of the honor type resolution is 0, and the result of the honor type flagship type resolution is 1.
TABLE 6
And step eight, the system reorders the binary configuration codes generated by analysis in the step seven according to the correct order of bytes/bits, converts the binary configuration codes into hexadecimal codes, and obtains the EOL configuration codes of the control unit under each single vehicle type. See table 7, the sequence of each bit is arranged in sequence under each byte, the value of 0 or 1 of each bit under each byte is obtained, then the binary code is converted into hexadecimal code, and the hexadecimal code of the AIC control unit under each single vehicle model, namely the EOL configuration code of the AIC control unit, is obtained through combination. The EOL configuration code of the AIC control unit under the honorable type is 9C9102, the configuration code under the honorable type is BD926A, and the configuration code under the flagship type is FDFABA.
TABLE 7
In conclusion, the method can solve the problems of low EOL configuration code rate, high error probability and difficulty in inspection of various control units under the condition of manually designing automobile products.
