In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a flowchart of another configuration updating method according to an embodiment of the present invention, and as shown in fig. 2, the method may include:
Optionally, as shown in fig. 3, the process of configuring the new configuration code for the idle configuration code bits reserved in the software upgrade package according to the new function may include:
and step 2011, detecting whether the reserved configuration code bits have idle configuration code bits.
The reserved configuration code bit refers to a configuration code bit which is temporarily unused and is reserved in the software upgrade package in the initial configuration period of the host, that is, the configuration code is not configured on the reserved configuration code bit, or the configuration code is configured on the reserved configuration code bit, but a function code is not configured on the configuration identifier corresponding to the configuration code.
When the configuration code bits are completely occupied, it is described that the configuration code identifiers corresponding to all the configuration codes on the configuration code bits are configured with functions, the functions are the existing functions in the host, and in order to enable the new functions not to affect the existing functions, the new configuration codes need to be configured on the code bits which are not completely occupied in the reserved configuration code bits, that is, the new configuration codes are configured on the idle configuration code bits. Therefore, before configuring the newly added configuration code bits in the idle configuration code bits, it is necessary to detect whether there are idle configuration code bits in the reserved configuration code bits.
Optionally, when the configuration code bit is reserved in the initial configuration period of the host, the idle configuration code bit or the configuration code in the idle configuration code bit may be marked, it is only necessary to detect whether the marked configuration code bit or the configuration code exists in the reserved configuration code bit or not during detection, when the marked configuration code bit or the configuration code exists in the reserved configuration code bit, it is described that the idle configuration code bit exists in the reserved configuration code bit, and when the marked configuration code bit or the configuration code does not exist in the reserved configuration code bit, it is described that the idle configuration code bit does not exist in the reserved configuration code bit.
For example, in the initial configuration period of the automobile host, a total of 6 data bytes (english: DataByte) are set in the memory, the 6 data bytes have 48 configuration code bits, the configuration code bits may be referred to as bits (english: Bit) in binary, the corresponding relationship between the 6 data bytes and the 48 configuration code bits please refer to table 1, and it can be seen from table 1 that the data byte 1 corresponds to 8 configuration code bits from byte 0 to byte 7.
TABLE 1
| Data Byte | Bit7 | Bit6 | Bit5 | Bit4 | Bit3 | Bit2 | Bit1 | Bit0 |
| Data#1 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| Data#2 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 |
| Data#3 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 |
| Data#4 | 31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 |
| Data#5 | 39 | 38 | 37 | 36 | 35 | 34 | 33 | 32 |
| Data#6 | 47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 |
When the reserved configuration code bits have the idle configuration code bits, the total number of the configuration codes needing to be newly added can be determined according to the total number of the functions needing to be newly added during the configuration updating, then the total number of the configuration code bits corresponding to the configuration codes needing to be newly added is determined according to the coding method used during coding, the newly added configuration codes are configured for the configuration code bits, the corresponding relation between the newly added configuration codes and the newly added functions is established according to the configuration result, and meanwhile, the corresponding relation is stored in the software upgrading package to obtain the software upgrading package after the configuration codes are updated. The new function refers to a function that the host does not have originally, for example: the video playing function, the music playing function, the backing image function with an auxiliary line, the backing image function without an auxiliary line, the function without backing assistance and the like.
Illustratively, assuming that the idle configuration code bits are 43 and 44 bits, the total number of functions required to be added in the configuration update is 3, the 3 added functions are respectively a backup image function with auxiliary lines, a backup image function without auxiliary lines and a function without backup assistance, the coding method used when the configuration code is configured according to the added functions is a binary coding method, the total number of the configuration codes required to be added can be determined to be 3 according to the total number of the functions required to be added, since 2 binary bits can represent 4 binary states, each binary state can represent 1 added function, it can be known that 2 configuration code bits can represent 3 added functions, that is, the configuration code can be configured for 3 added binary states in 4 binary states corresponding to the 43-bit and 44-bit configuration code bits, the remaining 1 binary state is marked by using a "NU LL" symbol to represent that the idle configuration code bits exist in the reserved configuration code bits, and the 3 added configuration codes and the 3 added functions are set as corresponding relations, the corresponding relation of the corresponding relation between the backup image code and the backup image function is set as 0, for example, the backup image function with 0 and the corresponding relation between the auxiliary line of the configuration code.
TABLE 2
| 43 bit | 44 position | New added function |
| 0 | 0 | Backing image function with auxiliary line |
| 0 | 1 | Backing image function without auxiliary line |
| 1 | 0 | Function without using backing assistance |
| NULL | NULL |
It should be noted that the encoding method used when configuring the configuration code according to the newly added function may also be an encoding method such as an octal, decimal, hexadecimal, or American Standard code Interchange (ASCII), which is not limited in the embodiment of the present invention.
The newly added function and the original function in the software upgrading package are obtained after the function code is configured on the configuration identifier, therefore, before configuring the code of the newly added function to the configuration identifier corresponding to the newly added function, the configuration identifier corresponding to the newly added function needs to be determined, the determined configuration identifier may be referred to as a target configuration identifier, which may at least consist of the newly added configuration code, and, in particular, when the newly added function is associated with the original function in the software upgrade package, the target configuration identifier corresponding to the newly added function is composed of the newly added configuration code and the configuration code of the original function associated with the newly added configuration code, the target configuration identifier is determined through step 203, when the newly added function is not associated with the original function in the software upgrade package, the target configuration identifier corresponding to the newly added function is composed of the newly added configuration code, and the target configuration identifier is determined through step 204.
When the newly added function is associated with the original function in the software upgrade package, the implementation of the newly added function is affected by the original function, and therefore, when determining the target configuration identifier of the newly added function, it is necessary to combine the configuration code corresponding to the function associated with the newly added function with the newly added configuration code to obtain the target configuration identifier, and store the obtained target configuration identifier in the software upgrade package after the configuration code is updated for use.
And step 204, when the newly added function is not associated with the original function in the software upgrading package, forming the newly added configuration code into a target configuration identifier.
When the new function is not associated with the original function in the software upgrade package, the implementation of the new function is not affected by the original function, so that the new configuration code corresponding to the new function is the target configuration identifier of the new function and is stored in the software upgrade package after the configuration code is updated.
For example, suppose that an original function in the software upgrade package is a corner sensing function (abbreviated as SAM function), the function is used to sense a turning action of an automobile, the configuration code bit corresponding to the function is 38 bits, the configuration code corresponding to the function is 1, the 3 newly added functions are a reversing image function with an auxiliary line, a reversing image function without an auxiliary line and a function without a reversing aid, and the corresponding relationship between the 3 newly added functions and the newly added configuration code please refer to table 2, because an automobile may turn during reversing, during the implementation process of the reversing image function with an auxiliary line and the reversing image function without an auxiliary line, both functions need to refer to the turning action of the automobile, that is, both functions are affected by the corner sensing function, for example: under the condition of no corner sensing function, the reversing image function with the auxiliary line and the reversing image function without the auxiliary line cannot know the turning of the automobile when in use, the host can display abnormal conditions, and a fault code can appear in a host system, so that the whole automobile cannot pass the inspection of the inspection equipment when off-line, and therefore, the reversing image function with the auxiliary line and the reversing image function without the auxiliary line can be determined to be in association with the corner sensing function. Therefore, the configuration code corresponding to the corner sensing function and the configuration code corresponding to the reversing image function with the auxiliary line form the target configuration identifier of the reversing image function with the auxiliary line, the configuration code corresponding to the corner sensing function and the configuration code corresponding to the reversing image function without the auxiliary line form the target configuration identifier of the reversing image function without the auxiliary line, the configuration code corresponding to the function without the reversing aid forms the target configuration identifier of the function without the reversing aid, and the target configuration identifiers corresponding to the 3 newly added functions please refer to table 3 (the oblique line in the cell in the column of the bit indicates that the value of the bit indicated by the column does not affect the implementation of the function indicated by the row of the cell, and the oblique line in the cell in the column of the newly added function indicates that the newly added function is not set), for example: "38-bit 1" and "43-bit 0" and "44-bit 0" constitute a target configuration flag of the reverse image function with the auxiliary line, and "43-bit 1" and "44-bit 0" constitute a target configuration flag of the function without the reverse assist.
TABLE 3
| 38 bit | 43 bit | 44 position | New added function |
| 1 | 0 | 0 | Backing image function with auxiliary line |
| 1 | 0 | 1 | Backing image function without auxiliary line |
| 1 | 0 | Function without using backing assistance | |
| NULL | NULL |
And step 205, configuring the function code for the target configuration identifier in the software upgrading package after the configuration code is updated according to the newly added function to obtain the software upgrading package after the code is updated.
After determining the target configuration identifier corresponding to the newly added function, the corresponding relationship between the target configuration identifier and the newly added function needs to be written in the software upgrade package after the configuration code is updated, and the function code is used in the software upgrading package after the configuration code is updated to define the new function, the realization of the new function in the function code needs to define the matching of the existing parts in the automobile, the preset action needed by each part when the new function is completed and the sequence of each preset action, so as to obtain the software upgrading package after the code is updated, after the configuration updating is finished according to the software upgrading package after the code updating, when the host receives an instruction which is triggered by a user and corresponds to the target configuration identifier, the parts in the automobile can execute preset actions according to the sequence specified in the function code, and further, the corresponding function is completed, and finally, the configuration updating of the host is completed on the premise of not adding new parts.
While configuring the function code for the target configuration identifier, it is also necessary to record the corresponding relationship between the target configuration identifier and the function code corresponding to the target configuration identifier in a software upgrade package after the code is updated, for example; the "38-bit 1" and the "43-bit 0" and the "44-bit 0" form a corresponding relationship between the target configuration identifier and the address of the corresponding function code, and the corresponding relationship is recorded in the software upgrade package after the code update, and the corresponding relationship may be recorded in a header file of the function code of the software upgrade package after the code update, or the corresponding relationship may be expressed in the function code by means of a pointer or the like.
It should be noted that, when the target configuration identifier configuration function code in the software upgrade package after the configuration code is updated according to the newly added function to obtain the software upgrade package after the code update, the software upgrade package may be separately set for the function code related to the newly added function, and the separately set software upgrade package does not include the function code corresponding to the original function of the host. When the system of the host is upgraded according to the independently set software upgrading packet, the time for upgrading the system can be shortened, and the efficiency of configuration updating is further improved.
And step 206, performing system upgrade on the host according to the software upgrade package after the code is updated.
Optionally, as shown in fig. 4, the process of performing system upgrade on the host according to the software upgrade package after code update may include:
The diagnostic instrument can be in serial communication with the host computer to complete data exchange between the diagnostic instrument and the host computer, and the setting of the host computer is refreshed according to the software upgrading packet after the codes are updated, so that the system upgrading is carried out on the host computer, and the configuration updating of the host computer is further completed. Because the diagnostic device needs to perform serial communication with the host, the diagnostic device is required to have enough configuration code bits to read the configuration code in the software upgrade packet after the code is updated, that is, the number of bits of the configuration code bits of the diagnostic device is required to be greater than or equal to the number of bits of the configuration code bits of the software upgrade packet after the code is updated, therefore, before performing system upgrade on the host, whether the number of bits of the configuration code bits of the diagnostic device is greater than or equal to the number of bits of the configuration code bits of the software upgrade packet after the code is updated needs to be judged, when the number of bits of the configuration code bits of the diagnostic device is greater than or equal to the number of bits of the configuration code bits of the software upgrade packet after the code is updated, the system upgrade can be performed on the host through the diagnostic device, that is, step 2062 is executed, when the number of bits of the configuration code bits of the diagnostic device is less than the number of bits of the configuration code bits of, and the system can not be upgraded by the diagnostic instrument until the digit of the configuration code bits of the diagnostic instrument is greater than or equal to the digit of the configuration code bits of the software upgrading packet after the code is updated.
Step 2062, when the digit of the configuration code bit of the diagnostic apparatus is larger than or equal to the digit of the configuration code bit of the software upgrading packet after the code is updated, the system upgrading is carried out on the host computer through the diagnostic apparatus.
Optionally, as shown in fig. 5, the process of performing system upgrade on the host by using the diagnostic apparatus may include:
When the system of the host computer is upgraded, the host computer can be upgraded according to different parts in the software upgrading package after the upgrading code is updated and the software upgrading package in the host computer, so that the time for upgrading the system can be effectively shortened, and the efficiency for updating the configuration can be further improved. The different part is mainly represented by the difference between the configuration identifier of the software upgrade package after the code is updated and the configuration identifier of the software upgrade package in the host, that is, the different part is mainly represented by the target configuration identifier and the corresponding function code. Therefore, before the upgrade, the configuration identifier of the software upgrade package in the host may be compared with the configuration identifier of the software upgrade package after the code update to determine whether an identifier different from the configuration identifier of the software upgrade package in the host exists in the configuration identifier of the software upgrade package after the code update, and when an identifier different from the configuration identifier of the software upgrade package in the host exists in the configuration identifier of the software upgrade package after the code update, the functional code corresponding to the different identifier is written into the host, that is, step 2062b is executed to complete the system upgrade of the host.
When the system of the host is upgraded, the functional code corresponding to the target configuration identifier can be found by inquiring the corresponding relation between the target configuration identifier stored in the software upgrading package after the code is updated and the corresponding functional code, and the functional code is written into the host, so that the configuration of the function corresponding to the target configuration identifier is realized, and the configuration update of the host is further completed. During the writing process, the diagnostic instrument may determine the number of parts included in the vehicle by obtaining a list of parts included in the vehicle, and looking up whether the list includes parts involved in the software upgrade package after the code update, to determine whether the parts in the vehicle can support the implementation of the newly added functions involved in the software upgrade package after code update, when the list contains the parts related to the software upgrading package after the code updating, the parts in the automobile can support the realization of the newly added functions related to the software upgrading package after the code updating, the function codes corresponding to different identifications can be written into the host, the writing process is mainly embodied as a process in which the diagnostic communication service of the diagnostic apparatus writes the configuration information and the parameter information into the host, and, and restarting the host after the writing process is finished, wherein the host can read the written configuration information and configuration parameters, and then the configuration update of the host is finished.

For example, assuming that the configuration identifier of the software upgrade package in the host is shown in table 4, and the configuration identifier of the software upgrade package after code update is shown in table 5, it can be known from a comparison between table 4 and table 5 that, in the configuration identifier of the software upgrade package after code update, an identifier different from the configuration identifier of the software upgrade package in the host exists, and the different identifier is: the target configuration identifier composed of "38-bit 1", "43-bit 0", and "44-bit 0", the target configuration identifier composed of "38-bit 1", "43-bit 0", and "44-bit 1", and the target configuration identifier composed of "43-bit 1" and "44-bit 0".
