Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle diagnosis, in particular to a diagnosis function display method, device, equipment and storage medium. BACKGROUND

[0002] With the continuous development of automobile electronics, there are more and more automobile parts manufacturers. Due to the factors of R&D cycle, information security and production cost, an automobile factory generally adopts multiple suppliers to supply the same ECU (Electronic Control Unit), that is, a multi-track ECU. The ECUs of different suppliers formulate diagnosis protocols and processes according to the needs of the automobile factory, most of which are the same, and some of which may be different due to different suppliers. This leads to the need to know which supplier the ECU of this vehicle is mounted on before diagnosing the differences.

[0003] Currently, there are two methods for developing diagnosis functions of a multi-track ECU: (1) all diagnosis functions are displayed, that is, after all diagnosis functions of the ECU are developed, all functions of the ECU are displayed in the diagnosis menu. For the same function with differences, the supplier name is added at the end of the function name, and the user selects the correct function for diagnosis when using it; (2) the VIN (Vehicle Identification Number) and the ECU list are mapped on the server. Each VIN has a corresponding ECU list, and each ECU has clear supplier information. When diagnosing a vehicle, the user uploads the vehicle VIN code to the server to obtain the information of each ECU, and displays the diagnosis function of the corresponding supplier ECU according to the obtained supplier information when executing the specific ECU function. However, both methods have disadvantages. The first method displays all functions of the ECU, which will lead to complicated menu items, and the unskilled user is easy to select and execute errors, which may seriously damage the ECU. The second method accurately finds through the server, which not only increases the R&D and maintenance cost of the automobile factory, but also may not be able to query and display in places with poor network.

[0004] As can be seen from the above, how to avoid complicated menu items to enable the diagnosis software to obtain and display the diagnosis function corresponding to the supplier of the ECU is a problem to be solved at present. SUMMARY

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Currently, displaying all ECU functions leads to cumbersome menu items, which can easily result in incorrect selections for inexperienced users, potentially damaging the ECU. Alternatively, precisely searching for ECU functions via a server not only increases the R&D and maintenance costs for automakers but may also fail to display the function in areas with poor network connectivity. Therefore, this application provides a diagnostic function display method. Based on a preset display interface, it shows a function menu composed of the names of each diagnostic function and the corresponding function interfaces. It allows real-time querying of the target ECU's supplier information, precise lookup of the diagnostic functions supported by the corresponding ECU based on the supplier number, and display of the function menu. By displaying the function interfaces corresponding to each function, ECU functions are decoupled, significantly improving development efficiency and accuracy, and reducing diagnostic software maintenance costs.

[0048] See Figure 1 As shown in the figure, an embodiment of the present invention discloses a method for demonstrating diagnostic functions, including:

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

[0050] In this embodiment, a communication relationship can be established between the diagnostic software and the target ECU of the target vehicle based on the vehicle gateway of the target vehicle. This communication relationship is then used to send a supplier information read command to the target ECU of the target vehicle via the diagnostic software. Based on the supplier information read command, the corresponding supplier information is obtained through the target ECU and sent to the diagnostic software. The vehicle gateway, acting as an interface between the vehicle's internal network and external devices (such as the diagnostic software), ensures the secure and efficient transmission of data.

[0051] Figure 2This is a schematic diagram of a supplier information request provided in this embodiment. When the diagnostic software (i.e., the diagnostic tool) detects an abnormality in the target vehicle, it sends a supplier information read request 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. Based on the target ECU, the supplier information is queried, and the supplier information is transmitted to the diagnostic software through the vehicle gateway.

[0052] Step S12: Use the supplier information to find the corresponding supplier number from the supplier mapping set, and use the supplier number to determine the target ECU tag from several ECU tags in the 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 parsed supplier names and corresponding supplier numbers. Specifically, the step of using the supplier information to find the corresponding supplier number from the supplier mapping set includes: constructing a supplier mapping set using the mapping relationship between the supplier names and corresponding supplier numbers in the supplier information, so as to find the corresponding supplier number from the supplier mapping set using the supplier names in the supplier information.

[0054] Figure 3 This is a schematic diagram illustrating the construction of a supplier mapping set provided in this embodiment. In one specific implementation, Supplier 1, Supplier 2, Supplier 3, and Supplier 4 are supplier names, and 0x01, 0x02, 0x04, and 0x08 are supplier numbers. The supplier names and supplier numbers have a one-to-one mapping relationship. Specifically, they are ordered in binary; for example, Supplier 2 corresponds to supplier number 0x02, which is 00000010 in binary; Supplier 3 corresponds to supplier number 0x04, which is 00000100 in binary. 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 is 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 4This embodiment provides a schematic diagram of ECU tags in a preset configuration file, which includes FunctionPath (name of the dynamic library file for the interface function call), Function (i.e., diagnostic function tag), FuncId (i.e., diagnostic function number), Supplier (i.e., supplier number), ChildFunc (tag used to determine whether there is a sub-function), FuncName (i.e., diagnostic function name), and FuncRef (i.e., function interface function).

[0056] Step S13: Based on the supplier field value and the supplier number in the target ECU label, determine the diagnostic function number in the diagnostic function label of the target ECU label.

[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. A bitwise AND operation is performed between the supplier field value and the supplier number. If the AND result matches the supplier number, the diagnostic function number in the diagnostic function tag of the target ECU tag is obtained. Specifically, determining the diagnostic function number in the diagnostic function tag of the target ECU tag based on the supplier field value and the supplier number includes: performing a bitwise AND operation between the supplier field value and the supplier number in the target ECU tag to obtain a corresponding AND result; if the AND result matches the supplier number, the diagnostic function number in the diagnostic function tag of the target ECU tag is obtained.

[0058] Step S14: Use the diagnostic function number to determine the name of each diagnostic function 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, an interface function is constructed using preset combination rules and based on the ECU name, diagnostic function name, and supplier name corresponding to the target ECU, and the interface function is saved to a dynamic library file. Specifically, before determining each diagnostic function name and corresponding function interface function in each diagnostic function tag using the diagnostic function number, the method further includes: constructing a function interface function corresponding to each diagnostic function name using preset combination rules and based on the ECU name, diagnostic function name, and supplier name corresponding to the target ECU, and saving the function interface function to a dynamic library file.

[0060] Understandably, all functions of the ECU are developed, with each function corresponding to a specific interface function. These functions are named with the ECU name, function name, and supplier name (if applicable). For example, a function named BCM_Learning_A represents the BCM controller learning function from supplier A; BCM_Learning_B represents the BCM controller learning function from supplier B; and a function named BCM_Learning with no supplier information indicates a more general BCM controller learning function. All functions are developed into a single dynamic library file for easy access by diagnostic software.

[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 name of each diagnostic function and the corresponding function interface function are obtained based on the determination result. Specifically, determining the name of each diagnostic function and the corresponding function interface function in each diagnostic function tag using the diagnostic function number includes: determining 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, then the function name tag and interface function tag in the diagnostic function tag and the sub-function tag are parsed respectively, and the name of each diagnostic function and the corresponding function interface function in the diagnostic function tag and the sub-function tag are obtained based on the parsing result.

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

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

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

[0065] As can be seen from the above, this application establishes supplier information and tag information corresponding to the target ECU of the target vehicle through a pre-constructed supplier mapping set and a preset configuration file. The supplier field value is obtained using the tag information in the target ECU tag, and a bitwise AND operation is performed between the supplier field value and the supplier number obtained from the supplier mapping set. If the result matches the supplier number, the diagnostic function number in the diagnostic function tag of the target ECU tag is obtained. The diagnostic function number is then used to obtain the name of each diagnostic function and its corresponding function interface function in each diagnostic function tag. In this way, a preset display interface shows the function menu composed of the names of each diagnostic function and the corresponding function interface function. The supplier information of the target ECU can be queried in real time, and the diagnostic functions supported by the corresponding ECU can be accurately queried based on the supplier number. The function menu is displayed, and by displaying the function interfaces corresponding to each function, the ECU functions are decoupled, greatly improving development efficiency and accuracy, and reducing the maintenance cost of diagnostic software.

[0066] Accordingly, seeFigure 6 As shown, this application also provides a diagnostic function demonstration device, including:

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

[0068] The target label determination module 12 is used to search for the corresponding supplier number from the supplier mapping set using the supplier information, and to determine the target ECU label from a number of ECU labels in the preset configuration file using the supplier number;

[0069] The function number determination module 13 is used to determine the diagnostic function number in the diagnostic function label of the target ECU label based on the supplier field value and the supplier number in the target ECU label;

[0070] The function display module 14 is used to determine the name of each diagnostic function and the corresponding function interface function in each diagnostic function label using the diagnostic function number, 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.

[0071] As can be seen from the above, this application establishes supplier information and tag information corresponding to the target ECU of the target vehicle through a pre-constructed supplier mapping set and a preset configuration file. The supplier field value is obtained using the tag information in the target ECU tag, and a bitwise AND operation is performed between the supplier field value and the supplier number obtained from the supplier mapping set. If the result matches the supplier number, the diagnostic function number in the diagnostic function tag of the target ECU tag is obtained. The diagnostic function number is then used to obtain the name of each diagnostic function and its corresponding function interface function in each diagnostic function tag. In this way, a preset display interface shows the function menu composed of the names of each diagnostic function and the corresponding function interface function. The supplier information of the target ECU can be queried in real time, and the diagnostic functions supported by the corresponding ECU can be accurately queried based on the supplier number. The function menu is displayed, and by displaying the function interfaces corresponding to each function, the ECU functions are decoupled, greatly improving development efficiency and accuracy, and reducing the maintenance cost of diagnostic software.
