Description

Technical Field

[0001] The present invention relates to the field of vehicle diagnosis technology, and in particular to a diagnostic function display method, device, equipment and storage medium. Background Art

[0002] With the continuous development of automotive electronics, there are more and more auto parts manufacturers. Considering factors such as R&D cycle, information security and production cost, automakers generally use multiple suppliers to supply the same ECU (Electronic Control Unit), that is, multi-track ECU. ECUs from different suppliers formulate diagnostic protocols and processes according to the needs of automakers. Most of the functions are the same, and some may differ from one supplier to another. As a result, when diagnosing the car, for the differences, it is necessary to first know which supplier the ECU is equipped with, and then select the correct diagnostic function in the diagnostic software to execute.

[0003] At present, there are two methods for developing diagnostic functions for multi-track ECUs: (1) Display all diagnostic functions, that is, after all diagnostic functions for the ECU are developed, all ECU functions are displayed in the diagnostic menu. For the same function with differences, the supplier name is added to the end of the function name, and the user selects the correct function diagnosis when using it; (2) Map the VIN (Vehicle Identification Number) and the ECU list on the server. Each VIN has a corresponding ECU list, and each ECU has clear supplier information. When diagnosing the vehicle, the user uploads the vehicle VIN code to the server to obtain the information of each ECU. When executing a specific ECU function, the diagnostic function of the corresponding supplier ECU is displayed according to the obtained supplier information. However, both methods have disadvantages. The first method displays all ECU functions, which will lead to cumbersome menu items. It is easy for unskilled users to choose to execute incorrectly, and in serious cases, the ECU may be damaged; the second method uses the server to accurately search, which will not only increase the R&D and maintenance costs of the automobile factory, but also may not be able to query and display in places with poor network.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] At present, displaying all the functions of the ECU will result in cumbersome menu items, which is easy for unskilled users to choose to execute incorrectly, and in serious cases, the ECU may be damaged; or accurately searching for ECU functions through the server will not only increase the R&D and maintenance costs of the automobile factory, but may also be unable to query and display in places with poor network. To this end, the present application provides a diagnostic function display method, which displays the function menu composed of each diagnostic function name and the function interface corresponding to the function interface function based on a preset display interface, can query the supplier information of the target ECU in real time, accurately query the diagnostic functions supported by the corresponding ECU according to the supplier number, and display the function menu. By displaying the function interface corresponding to each function, the ECU function is decoupled, which greatly improves the development efficiency and accuracy, and reduces the maintenance cost of the diagnostic software.

[0048] See also Figure 1 As shown, an embodiment of the present invention discloses a diagnostic function display method, including:

[0049] Step S11, when the target vehicle is detected to be abnormal by the diagnostic software, a supplier information reading command is sent to the target ECU of the target vehicle by the diagnostic software to obtain supplier information; the target ECU is an ECU that can be supplied by different suppliers.

[0050] In this embodiment, a communication relationship between the diagnostic software and the target ECU of the target vehicle can be established based on the vehicle gateway of the target vehicle, so as to utilize the communication relationship and send a supplier information reading command to the target ECU of the target vehicle through the diagnostic software; based on the supplier information reading command, the corresponding supplier information is obtained through the target ECU, and the supplier information is sent to the diagnostic software. The vehicle gateway serves as an interface between the internal network of the vehicle and external devices (such as diagnostic software), ensuring the safe and effective transmission of data.

[0051] Figure 2A supplier information request schematic diagram is provided for this embodiment. When the diagnostic software (i.e., the diagnostic instrument) detects an abnormality in the target vehicle, a supplier information read request is sent to the vehicle gateway. The supplier information read request includes a supplier information read command, so that the supplier information read command is sent to the target ECU corresponding to the target vehicle through the vehicle gateway, the supplier information is queried based on the target ECU, and the supplier information is transmitted to the diagnostic software through the vehicle gateway.

[0052] Step S12: using the supplier information to search for a corresponding supplier number from a supplier mapping set, and using the supplier number to determine a target ECU tag from a plurality of ECU tags in a preset configuration file.

[0053] In this embodiment, after obtaining the supplier information, the supplier information is parsed, and a supplier mapping set is constructed using the supplier name obtained by the parsing and the corresponding supplier number. Specifically, searching for the corresponding supplier number from the supplier mapping set using the supplier information includes: constructing a supplier mapping set using the mapping relationship between the supplier name in the supplier information and the corresponding supplier number, so as to search for the corresponding supplier number from the supplier mapping set using the supplier name in the supplier information.

[0054] Figure 3 A schematic diagram of constructing a supplier mapping set provided for this embodiment. In a specific implementation, supplier 1, supplier 2, supplier 3, and supplier 4 are supplier names, 0x01, 0x02, 0x04, and 0x08 are supplier numbers, and the supplier names and supplier numbers are in a one-to-one mapping relationship. Among them, in binary sorting, such as the supplier number corresponding to supplier 2 is 0x02, and the corresponding binary is 00000010; the supplier number corresponding to supplier 3 is 0x04, and the corresponding binary is 00000100. After constructing the supplier mapping set, the corresponding supplier number can be found from the supplier mapping set based on the supplier name in the supplier information.

[0055] It can be understood that after obtaining the supplier number, the target ECU tag containing the supplier number is determined from the preset configuration file based on the supplier number. Figure 4A schematic diagram of ECU labels in a preset configuration file provided for this embodiment, including FuntionPath (dynamic library file name called by interface function), Function (i.e. diagnostic function label), FuncId (i.e. diagnostic function number), Supplier (i.e. supplier number), ChildFunc (label for determining whether there is a sub-function), FuncName (i.e. diagnostic function name), and FuncRef (i.e. functional interface function).

[0056] Step S13: Determine the diagnostic function number in the diagnostic function tag in the target ECU tag based on the vendor field value in the target ECU tag and the vendor number.

[0057] In this embodiment, after obtaining the target ECU tag, the supplier field value corresponding to the supplier number in the target ECU tag is obtained, and the supplier field value and the supplier number are ANDed. If the ANDed result is consistent with the supplier number, the diagnostic function number in the diagnostic function tag in the target ECU tag is obtained. Specifically, the diagnostic function number in the diagnostic function tag in the target ECU tag is determined based on the supplier field value and the supplier number in the target ECU tag, including: performing an ANDed operation on the supplier field value in the target ECU tag and the supplier number to obtain a corresponding ANDed result; if the ANDed result is consistent with the supplier number, the diagnostic function number in the diagnostic function tag in the target ECU tag is obtained.

[0058] Step S14, using the diagnostic function number to determine each diagnostic function name in each diagnostic function label and the corresponding function interface function, so as to display the function menu composed of each diagnostic function name and the function interface corresponding to the function interface function based on the preset display interface of the diagnostic software.

[0059] In this embodiment, the interface function is constructed based on the ECU name, diagnostic function name and supplier name corresponding to the target ECU using the preset combination rule, and the interface function function is saved in the dynamic library file. Specifically, before the diagnostic function number is used to determine each diagnostic function name in each diagnostic function label and the corresponding function interface function, it also includes: constructing the function interface function corresponding to each diagnostic function name based on the ECU name, diagnostic function name and supplier name corresponding to the target ECU using the preset combination rule, and saving the function interface function in the dynamic library file.

[0060] It is understandable that all functions of the ECU are developed, and one function corresponds to one function interface function, and the function is composed of ECU name + function name + supplier name (if any). For example, the composed function interface function is BCM_Learning_A, which means the BCM controller learning function with supplier name A; the function interface function is BCM_Learning_B, which means the BCM controller learning function with supplier name B; the function interface function is BCM_Learning, and there is no supplier information in the suffix, which means that this is a more general BCM controller learning function. All functions are developed in a dynamic library file to facilitate the diagnostic software to call.

[0061] In this embodiment, after obtaining the diagnostic function number, the diagnostic function number is used to determine whether the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag, and the names of each diagnostic function and the corresponding function interface function are obtained based on the judgment result. Specifically, the use of the diagnostic function number to determine the names of each diagnostic function in each diagnostic function tag and the corresponding function interface function includes: using the diagnostic function number to determine whether the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag; if the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag, the function name tag and the interface function tag in the diagnostic function tag and the sub-function tag are parsed respectively, and the names of each diagnostic function in the diagnostic function tag and the sub-function tag and the corresponding function interface function are obtained based on the parsing result.

[0062] Further, when using the diagnostic function number to determine whether the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag, if the diagnostic function number is a first preset value, it indicates that the diagnostic function tag corresponding to the diagnostic function number does not have a sub-function tag; if the diagnostic function number is a second preset value, it indicates that the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag. Specifically, using the diagnostic function number to determine whether the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag includes: if the diagnostic function number is a first preset value, it indicates that the diagnostic function tag corresponding to the diagnostic function number does not have a sub-function tag; if the diagnostic function number is a second preset value, it indicates that the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag.

[0063] In a specific implementation, the diagnostic function number is used to determine whether the diagnostic function tag corresponding to the diagnostic function number has a sub-function tag. If the diagnostic function number is 0, then the diagnostic function tag corresponding to the diagnostic function number does not have a sub-function tag; if the diagnostic function number is 1, then the diagnostic function tag corresponding to the diagnostic function number has a corresponding sub-function tag. Therefore, it is necessary to parse the diagnostic function tag and the function name label and interface function label in the sub-function label respectively to obtain the diagnostic function name and the corresponding function interface function in the diagnostic function tag and the sub-function label.

[0064] In this embodiment, Figure 5 A schematic diagram of ECU function display is provided for this embodiment. After obtaining the diagnostic function number, the diagnostic function name corresponding to the diagnostic function number is sorted using the diagnostic function number, a function menu is composed based on the sorted diagnostic function names, and the function menu and the function interface corresponding to the function interface function are displayed using the preset display interface of the diagnostic software. Specifically, the function menu composed of each diagnostic function name and the function interface corresponding to the function interface function are displayed based on the preset display interface of the diagnostic software, including: obtaining the diagnostic function number corresponding to each diagnostic function name, and sorting each diagnostic function name using the diagnostic function number corresponding to each diagnostic function name to obtain a function menu; displaying the function menu and the function interface corresponding to the function interface function based on the preset display interface of the diagnostic software.

[0065] As can be seen from the above, the present application establishes supplier information and label information corresponding to the target ECU of the target vehicle through a pre-constructed supplier mapping set and a preset configuration file, obtains the supplier field value using the label information in the target ECU label, and performs an AND operation on the supplier field value and the supplier number obtained by the supplier mapping set. If the operation result is consistent with the supplier number, the diagnostic function number in the diagnostic function label in the target ECU label is obtained, so as to obtain the names of each diagnostic function in each diagnostic function label and the corresponding function interface function using the diagnostic function number. In this way, based on the preset display interface, the function menu composed of each diagnostic function name and the function interface corresponding to the function interface function are displayed, the supplier information of the target ECU can be queried in real time, the diagnostic functions supported by the corresponding ECU can be accurately queried according to the supplier number, and the function menu is displayed. By displaying the function interface corresponding to each function, the ECU function is decoupled, which greatly improves the development efficiency and accuracy, and reduces the maintenance cost of the diagnostic software.

[0066] Accordingly, see Figure 6 As shown, the present application also provides a diagnostic function display device, including:

[0067] The command sending module 11 is used to send a supplier information reading command to a target ECU of the target vehicle through the diagnostic software to obtain supplier information when an abnormality is detected in the target vehicle through the diagnostic software; the target ECU is an ECU that can be supplied by different suppliers;

[0071] As can be seen from the above, the present application establishes supplier information and label information corresponding to the target ECU of the target vehicle through a pre-constructed supplier mapping set and a preset configuration file, obtains the supplier field value using the label information in the target ECU label, and performs an AND operation on the supplier field value and the supplier number obtained by the supplier mapping set. If the operation result is consistent with the supplier number, the diagnostic function number in the diagnostic function label in the target ECU label is obtained, so as to obtain the names of each diagnostic function in each diagnostic function label and the corresponding function interface function using the diagnostic function number. In this way, based on the preset display interface, the function menu composed of each diagnostic function name and the function interface corresponding to the function interface function are displayed, the supplier information of the target ECU can be queried in real time, the diagnostic functions supported by the corresponding ECU can be accurately queried according to the supplier number, and the function menu is displayed.
