[0068] In the following description, specific details such as specific system module structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application.

[0069] The vehicle diagnostic method provided in the embodiment of the present application can be applied to an electronic device, wherein the electronic device is communicatively connected to a target vehicle, and the electronic device is connected to an on-board diagnostic system module in the target vehicle by wire or wireless connection, thereby achieving a communication connection between the electronic device and the vehicle. Specifically, the vehicle diagnostic method can be implemented by application software in the electronic device, and the electronic device can be a diagnostic instrument, diagnostic equipment, mobile phone, tablet computer, laptop computer, netbook, personal digital assistant (PDA) and other terminals. The embodiment of the present application does not impose any restrictions on the specific type of the electronic device.

[0070] In order to illustrate the technical solution described in this application, a specific embodiment is provided below.

[0071] Embodiment 1

[0072] See also Figure 1 , shows a schematic flow chart of a vehicle diagnostic method provided by an embodiment of the present application, the method comprising:

[0073] Step S101, when a selection instruction of a target vehicle type is detected, a preset function menu list corresponding to the target vehicle type is displayed.

[0074] Specifically, when it is detected that the user inputs the target vehicle model information, or the vehicle identification code of the target vehicle connected to the electronic device is automatically obtained, and the vehicle model information of the target vehicle (which may be referred to as the target vehicle model) is parsed according to the vehicle identification code, a preset function menu list corresponding to the target vehicle model is displayed. After selecting the vehicle model, the system module menu is no longer listed, but the function menu is directly listed, which can reduce the operation of displaying the system module for selection, avoid the appearance of repeated interfaces, and the user can perform corresponding operations on the function menu.

[0075] Step S102: when a selection instruction of a target function menu item is detected, a preset system module list corresponding to the target function menu item is displayed.

[0076] Specifically, the target function menu item is selected from the preset function menu list. When an operation of selecting a function menu item from the preset function menu list is detected, it is determined that a selection instruction of the target function menu item is detected, and the selected function menu item is referred to as the target function menu item. When the selection instruction of the target function menu item is detected, a preset system module list corresponding to the target function menu item is displayed, and the preset system module list includes identification information of all system modules associated with the target function menu item.

[0077] In one application scenario, for example, the selection instruction of a target function menu item can be obtained by selecting the target function menu item and displaying a preset system module list corresponding to the target function menu item. The list can be a pop-up box or a menu displaying all system modules pre-associated with the target function menu item, so that the user can select a specific system module.

[0078] Step S103: when a subscription instruction of a target system module is detected, a target interface function matching the target system module is called.

[0079] Specifically, the target system module is selected from the preset system module list. After the preset system module list corresponding to the target function menu item is displayed, when a selection operation on a specific system module selected from the preset system module list is detected, it is determined that a subscription instruction of the target system module is detected. Since the target function menu item may correspond to multiple system modules and multiple interface functions, when a subscription instruction of the target system module is detected, an interface function matching the target system module may be called in the interface function corresponding to the target function menu item, and the interface function matching the target system module is referred to as a target interface function.

[0080] Step S104: executing a diagnostic function corresponding to the target function menu item on the target system module through the target interface function.

[0081] Specifically, the diagnostic function corresponding to the target function menu item can be executed through the target interface function corresponding to the target system module. For example, the user can change the specific type of the selected target system module through the subscription instruction, and the target interface function will also change accordingly. Therefore, the target function menu item is not bound to a fixed interface function, and can flexibly adapt to changes in external diagnostic logic. It has good applicability, low coupling, and high convenience in modifying programs or menu items.

[0082] In an application scenario, when a selection instruction of a target vehicle model is detected, a preset function menu list corresponding to the target vehicle model is displayed. For example, in the preset function menu list, the user can right-click to select the target function menu item, and a pop-up box or menu will display all system modules pre-associated with the target function menu item. The user can select a specific system module. When the selected specific system module is detected, it is determined that the subscription instruction of the target function menu item is detected, and the system module selected by the user is called the target system module. In the interface function corresponding to the target function menu item, the interface function matching the target system module is called, so that the interface function matching the target system module and the target function menu item can be determined. For example, if the target management system is EMS, the target function menu item is to flash the ECU, and the target interface function is: an interface function for the diagnostic function of the ECU flash in the EMS.

[0083] When the embodiment of the present application detects a selection instruction for a target vehicle model, a preset function menu list corresponding to the target vehicle model is displayed. The target function menu item can be directly selected according to the displayed preset function menu list. According to the subscription instruction, the target interface function matching the target system module is called. The system modules selected by the subscription instruction are different, and the called interface function will also be different. Therefore, a function menu item will not be bound to a fixed interface function. The embodiment of the present application can flexibly adapt to changes in external diagnostic logic and has good applicability, so that the coupling between the menu item and the program is low, and the modification of the program or menu item is convenient.

[0084] Embodiment 2

[0085] This embodiment is a further explanation of the first embodiment. For details of the same or similar parts as the first embodiment, please refer to the relevant description of the first embodiment, which will not be repeated here. Each diagnostic function is pre-compiled into a separate dynamic link library; each of the dynamic link libraries encapsulates multiple system modules for implementing the interface functions of the corresponding diagnostic function; each function menu item in the preset function menu list is associated with the corresponding dynamic link library; the implementation of the function corresponding to the diagnostic function and the call of the function can be separated in advance, and the diagnostic function programs corresponding to the same function in different system modules are pre-encapsulated into the same dynamic link library, that is, one dynamic link library includes multiple diagnostic function programs with the same function but from different system modules, and each diagnostic function program has an interface function for external calls, and the corresponding diagnostic function can be executed through the interface function.

[0086] like Figure 2 As shown, after the selection instruction of the target function menu item is detected, step S203 is also included, and the corresponding step S103 includes step S204. The vehicle diagnosis method in this embodiment includes:

[0087] Step S201, when a selection instruction of a target vehicle type is detected, a preset function menu list corresponding to the target vehicle type is displayed.

[0088] Specifically, for the parts where step S201 is identical or similar to the above-mentioned step S101, please refer to the relevant description of step S101, which will not be repeated here.

[0089] Step S202: when a selection instruction of a target function menu item is detected, a preset system module list corresponding to the target function menu item is displayed.

[0090] Specifically, the parts where step S202 is identical or similar to the above-mentioned step S102 can be specifically referred to the relevant description of step S102, which will not be repeated here.

[0091] Step S203, searching for a target dynamic link library corresponding to the target function menu item.

[0092] Specifically, since each function menu item is associated with a dynamic link library in advance, after detecting the subscription instruction of the target function menu item, the target dynamic link library corresponding to the target function menu item is searched. For example, if function menu item A is for flashing the ECU, the corresponding dynamic link library includes the interface functions of multiple system modules (such as EMS, BCM, ICM, etc.) for flashing the ECU, and function menu item B is for clearing fault codes of the EUC, and the corresponding dynamic link library includes the interface functions of multiple system modules (such as EMS, BCM, ICM, etc.) for clearing fault codes of the ECU.

[0093] Step S204, when a subscription instruction of a target system module is detected, a target interface function matching the target system module is called from the target dynamic link library.

[0094] Specifically, the above-mentioned calling of the target interface function matching the target system module may be: calling the target interface function matching the target system module from the target dynamic link library. When the user inputs the subscription instruction of the target function menu item, the target system module is subscribed according to the subscription instruction, and the interface functions of multiple system modules are pre-packaged in the target dynamic link library. The target system module is subscribed according to the subscription instruction, and the target interface function matching the target system module is called from the target dynamic link library.

[0095] In one embodiment, the identification information of each interface function in each dynamic link library and the identification information of the corresponding system module can be first associated into a key-value pair for storage, the key value in the key-value pair represents the identification information of the interface function, and the key name in the key-value pair represents the identification information of the system module; the interface function in each dynamic link library and the identification information of the system module corresponding to the interface function are pre-associated into a key-value pair for storage, which can be specifically stored through a map data structure. The key-value pair includes a key value (also called a value or value) and a key name (also called a key or key), with the identification information of the interface function as the key value and the identification information of the system module as the key name. If the identification information of the interface function is the ECU flash of the engine management system, the identification information of the corresponding system module is the identification information of the engine management system. Calling the target interface function matching the target system module from the target dynamic link library may be as follows: in the key-value pairs stored in the target dynamic link library, using the identification information of the target system module as the target key name, searching for the target key value corresponding to the target key name; determining the identification information of the target interface function according to the target key value, and indexing the target interface from the target dynamic link library according to the identification information of the target interface function for calling, thereby realizing fast calling of the target interface function.

[0096] Step S205: executing a diagnostic function corresponding to the target function menu item on the target system module through the target interface function.

[0097] Specifically, the details of the same or similar parts of step S205 and the above-mentioned step S104 can be found in the relevant description of step S104, which will not be repeated here.

[0098] In this embodiment, each diagnostic function is pre-compiled into a separate dynamic link library; each of the dynamic link libraries encapsulates multiple system modules for implementing interface functions of corresponding diagnostic functions; each function menu item in the preset function menu list is associated with the corresponding dynamic link library, and the target dynamic link library corresponding to the target function menu item can be searched, the target dynamic link library includes interface functions from multiple system modules, and the target interface function matching the target system module selected by the subscription instruction is directly called from the target dynamic link library. Therefore, the corresponding interface function of the target function menu item can be dynamically executed, without binding the target function menu item and the separate interface function. The interface function corresponding to the target function menu item is modified, and the dynamic link library can be directly modified or re-packaged, which has good applicability, low coupling, and high convenience in modifying programs or function menu items.

[0099] Embodiment 3

[0100] This embodiment is a further description of the first or second embodiment. For details of the same or similar parts as the first or second embodiment, please refer to the relevant description of the first or second embodiment, which will not be repeated here. Figure 3 As shown, the above step S103 includes steps S303 to S305, and step S104 includes step S306. The vehicle diagnosis method in this embodiment includes:

[0101] Step S301, when a selection instruction of a target vehicle type is detected, a preset function menu list corresponding to the target vehicle type is displayed.

[0102] Specifically, for the parts where step S301 is identical or similar to the above-mentioned step S101, please refer to the relevant description of step S301, which will not be repeated here.

[0103] Step S302: when a selection instruction of a target function menu item is detected, a preset system module list corresponding to the target function menu item is displayed.

[0104] Specifically, the parts where step S302 is identical or similar to the above-mentioned step S102 can be specifically referred to the relevant description of step S102, which will not be repeated here.

[0105] Step S303: when a subscription instruction of the target system module is detected, the subscription instruction is parsed.

[0106] Specifically, when a subscription instruction of a target function menu item is detected, it is analyzed whether the identification information of the target system module included in the subscription instruction includes identification information of multiple target system modules.

[0107] Step S304: if it is parsed that the subscription instruction includes identification information of multiple target system modules, the execution order of the multiple target system modules is determined.

[0108] In one embodiment, determining the execution order of the plurality of target system modules includes: determining the execution order as the selection order of the plurality of target system modules selected by the user in the preset system module list.

[0109] Specifically, if it is parsed that the subscription instruction includes identification information of multiple target system modules, the user's selection order information of the multiple target system modules can be determined as the execution order of the multiple target system modules, or the execution order of the multiple target system modules can be determined according to a preset default execution order.

[0110] Step S305 , calling the target interface functions corresponding to the plurality of target system modules respectively in sequence according to the execution order.

[0111] Specifically, according to the determined execution order, target interface functions corresponding to the multiple system modules are called in sequence according to the execution order of the multiple target system modules, so as to execute the multiple target interface functions in sequence to perform the corresponding diagnostic functions.

[0112] Step S306: according to the execution order, the diagnostic function corresponding to the target function menu item is executed on each target system module in turn through each target interface function.

[0113] Specifically, the diagnostic function corresponding to the target function menu item can be executed according to the execution order of the multiple target system modules through each of the target interface functions corresponding to the multiple target system modules in sequence.

[0114] In a specific application scenario, for example, the subscription instruction includes two target system modules EMS and BCM selected in sequence, then the system module names corresponding to the two target system modules EMS and BCM will be stored in sequence in the queue specified by the target function menu item, and the target interface functions in the two target systems EMS and BCM will be called in sequence, and then the target interface function corresponding to EMS will be executed first, and then the target interface function corresponding to BCM will be executed, so that multiple related functions can be executed according to the target function menu item.

[0115] This embodiment can directly subscribe to the identification information of multiple target system modules included in the instruction, and call the target interface functions corresponding to the multiple target system modules in sequence, so as to execute the multiple target interface functions in sequence to perform the corresponding diagnostic functions. The corresponding diagnostic functions are executed by the multiple target interface functions, the operation is simple, and multiple functions of the vehicle can be diagnosed quickly, thereby improving the diagnostic efficiency of the vehicle.

[0117] This embodiment is a further description of the first embodiment. For details of the same or similar parts as the first embodiment, please refer to the relevant description of the first embodiment, which will not be repeated here. The above subscription instruction includes a first subscription instruction and a second subscription instruction. Figure 4 As shown, the above step S103 includes steps S403 to S404, and the above step S104 includes step S405. The vehicle diagnosis method in this embodiment includes:

[0118] Step S401, when a selection instruction of a target vehicle type is detected, a preset function menu list corresponding to the target vehicle type is displayed.

[0120] Step S402: when a selection instruction of a target function menu item is detected, a preset system module list corresponding to the target function menu item is displayed.

[0121] Specifically, the parts where step S402 is identical or similar to the above-mentioned step S102 can be specifically referred to the relevant description of step S102, which will not be repeated here.

[0122] Step S403, when a first subscription instruction of a target system module is detected, a preset logic module list corresponding to a target interface function matching the target system module is displayed; wherein the first subscription instruction includes identification information of the target system module.

[0123] Specifically, after displaying the preset function menu list corresponding to the target vehicle model, the target function menu item is selected based on the menu options in the preset function menu list, and a first subscription instruction for the target function menu item is input, the first subscription instruction includes identification information for selecting a specific system module, and when the subscription instruction for the target function menu item is detected, according to the identification information of the target system module, a target interface function matching the target system module is determined in the interface function associated with the target function menu item, and the target interface function contains a plurality of preset internal key logic modules, and then a list of identifications of the plurality of preset internal key logic modules in the target interface function is displayed (i.e. a list of preset logic modules corresponding to the target interface function matching the target system module), and the user can select the diagnostic function corresponding to the internal key logic of the target interface function that needs to be executed based on the list of multiple internal key logic module identifications.

[0124] In one embodiment, the identification information of each interface function and the identification information of all key logic modules in the corresponding interface function are pre-composed into a structure, and a structure corresponding to each interface function and the identification information of the corresponding system module are associated into a key-value pair for storage; when the first subscription instruction of the target system module is detected, a preset logic module list corresponding to the target interface function matching the target system module is displayed, including: when the first subscription instruction of the target function menu item is detected, the target dynamic link library corresponding to the target function menu item is searched; in the key-value pairs stored corresponding to the target dynamic link library, the identification information of the target system module is used as the target key value name, and the target structure corresponding to the target key value name is searched; according to the preset key logic module identification information included in the target structure, the corresponding preset key logic module identification list is displayed.

[0125] Specifically, the interface functions of the same functions in different system modules can be pre-encapsulated into the same dynamic link library, and each function menu item can be associated with the corresponding dynamic link library; there will be multiple interface functions in a dynamic link library, and each interface function in each dynamic link library and the identification information of the key logic module corresponding to the interface function will form a structure, that is, the identification information of the interface function and the identification information of the key logic module are used as member data in a structure, and each interface function will correspond to a structure, and then the structure is used as the key value, and the identification information of the system module associated with the corresponding interface function of the structure is used as the key value name to associate into a key-value pair for storage. When the first subscription instruction of the target function menu item is detected, the target dynamic link library corresponding to the target function menu item is searched; in the key-value pair corresponding to the target dynamic link library, the identification information of the target system module is used as the target key value name, and the target structure corresponding to the target key value name is searched, and the preset key logic module identification information included in the target structure is displayed as a corresponding preset key logic module identification list through a preset display method for user selection.

[0126] Step S404, when a second subscription instruction of a target logic module is detected, a logic function corresponding to the target logic module is called and written into the target interface function; wherein the target logic module is selected from the preset logic module list, and the second subscription instruction includes identification information of the target logic module.

[0127] Specifically, the identification information of the key logic module is selected from the preset key logic module identification list through the second subscription instruction, and the logic function in the target interface function that matches the second subscription instruction is called (the logic function can be a subroutine preset according to the corresponding diagnostic function) to execute the diagnostic function corresponding to the logic function. Among them, the second subscription instruction can be to select one or more key logic module identifications in the displayed preset key logic module identification list, and each key logic module identification corresponds to the corresponding subroutine in the corresponding interface function to implement the corresponding logic function. The above-mentioned writing it into the target interface function can be: the identification information of the logic function corresponding to the target logic function is passed back to the target interface function as a parameter, so that when the target interface function is called, the subroutine corresponding to the identification information of the logic function in the target interface function is executed, thereby realizing the execution of the logic function corresponding to the target logic module in the target interface function.

[0128] For example, the corresponding interface function of a certain system implements a flashing function, which has multiple flashing modes, and different flashing modes have different processing methods. When a user can subscribe to the flashing function of the system through the first subscription instruction, the identification information of different flashing modes can be exported (that is, when the first subscription instruction of the target system module is detected, the preset logic module list corresponding to the target interface function matching the target system module is displayed), and the user can select the flashing mode through the second subscription instruction, and this subscribed mode is passed back to the interface function as a parameter (that is, when the second subscription instruction of the target logic module is detected, the logic function corresponding to the target logic module is called and written into the target interface function).

[0129] Step S405, executing the target interface function according to the logic function corresponding to the target logic module, so as to implement the diagnostic function corresponding to the target function menu item on the target system module.

[0130] Specifically, the logic function corresponding to the target logic module is called and written into the target interface function. According to the target interface function in which the logic function identification information corresponding to the target logic module has been written, the logic function corresponding to the identification information of the target logic function in the target interface function is executed. The internal logic of the target interface function can be subscribed to, thereby realizing the subscription of the internal logic of the interface function.

[0134] Specifically, for the parts where step S501 is identical or similar to the above-mentioned step S101, please refer to the relevant description of step S101, which will not be repeated here.

[0135] Step S502, if a selection instruction of a target function menu item is detected, a default subscription instruction corresponding to the target function menu item is obtained; wherein the default subscription instruction is a historical subscription instruction or a pre-specified subscription instruction; the default subscription instruction includes identification information of a target system module.

[0136] Specifically, the user may not input the corresponding subscription instruction for the target function menu item. When the selection instruction of the target function menu item is detected, the default subscription instruction of the target function menu item is directly obtained. The default subscription instruction may be the most recently input subscription instruction, or the default subscription instruction may also be a pre-stored subscription instruction.

[0137] Step S503: calling a target interface function that matches the target system module, and executing a diagnostic function corresponding to the target function menu item on the target system module through the target interface function.

[0139] In one embodiment, when a modification instruction for the default subscription instruction is received, the identification information of the original target system module of the default subscription instruction is changed to the identification information of the new target system module according to the modification instruction; wherein the modification instruction includes the identification information of the new target system module.

[0140] Specifically, the identification information of the system module associated in the default subscription instruction can be modified or deleted. The user can input a modification instruction containing the identification information of the new target system module to be associated, and based on the identification information of the new target system module, the identification information of the target system module currently stored in the default subscription instruction can be changed to the identification information of the new target system module.

[0141] Since the embodiment of the present application can directly detect the selection instruction of the target function menu item, the default subscription instruction corresponding to the target function menu item is obtained, and the target interface function matching the target system module corresponding to the default subscription instruction is directly executed. The diagnostic function corresponding to the target function menu item is executed on the target system module through the target interface function. The operation is simple, the vehicle functions can be diagnosed quickly, and the diagnostic efficiency of the vehicle is improved.
