FIG. 1 is a schematic diagram of an automobile diagnostic system involved in the present application. As shown in FIG. 1, the car diagnostic system includes a car 100, a diagnostic device 200, and a shared server 300.

The sharing server 300 is configured to store shared data, and the shared data includes operation functions that all the diagnostic devices 200 may perform and operation paths corresponding to the operation functions. Among them, the operation function is a user instructing the diagnosis operation performed by the diagnosis device 200, such as reading a diagnostic code of a car engine system fault code, or a brake code of a car braking system, and the operation path is to enter the automobile when the diagnosis device 200 performs a corresponding operation function The entry path of the system.

Different operation functions correspond to different operation paths. For example, the operation function for reading the fault code of the car transmitter system, the corresponding operation path can be "System selection → Engine system → Read fault code"; and for reading the fault of the car brake system Code operation function, the corresponding operation path can be "system selection → braking system → read fault code".

Diagnostic software is run in the diagnostic device 200 to query the operation path corresponding to the operation function from the shared server 300 according to the operation function triggered by the user in the diagnostic software, so that the vehicle 100 is automatically executed to correspond to the operation function according to the operation path found. Diagnostic operations. Taking the operation path “System Selection → Engine System → Read DTC” as an example, the diagnostic device 200 enters the engine system of the automobile 100 according to this operation path, and performs the operation of reading the engine DTC. The diagnostic device 200 may be a smart phone, a tablet computer, a notebook computer, a computer, or any other electronic device capable of running diagnostic software.

The number of diagnostic devices 200 is at least one (three shown in FIG. 1), and these diagnostic devices 200 query the operation paths corresponding to the respective operation functions from the shared server 300 to connect to each of them according to the operation paths found The car 100 performs a corresponding diagnosis operation.

FIG. 2 is a flowchart of a method for car diagnosis shown in an exemplary embodiment. The method is applicable to the diagnosis device 200 shown in the car diagnosis system in FIG. 1. As shown in FIG. 2, the method may include the following steps:

In step 210, a function execution instruction of a car diagnosis is obtained, and the function execution instruction includes a target function instructing execution.

In one embodiment, the function execution instruction of the car diagnosis is generated by the diagnosis software according to a trigger operation of the user in the diagnosis software interface.

Among them, the diagnostic software interface is provided with several operation portals, and these operation portals respectively correspond to the operation functions that the diagnostic equipment automatically performs on the diagnosis car. For example, the diagnostic software interface is provided with an operation entry for "reading the engine engine system fault code". If the user wants the diagnostic equipment to perform the operation function of reading the engine engine system fault code, the operation entry can be triggered accordingly.

The operation entry set on the diagnostic software interface may also include an operation entry for "reading a car brake system fault code", an operation entry for "reading a car steering system fault code", etc., which are not limited here.

In another embodiment, the function execution instruction of the car diagnosis may also be generated by the diagnosis software according to the recognition result of the voice signal input by the user, or the diagnosis device may detect that the function button configured by the user is triggered by the user. Generated accordingly.

The diagnostic operation performed by the diagnostic device indicated by the function execution instruction on the diagnosis of the car is the target function indicated by the function execution instruction, for example, the user triggers the "read the engine engine system fault code" operation entry generated by the function execution instruction indicated by the target The function is to read the fault code of the engine system from the car system.

In step 230, according to the function execution instruction request, all shared operation paths are queried for a target operation path corresponding to the target function.

Among them, in one embodiment, all shared operation paths are stored in the shared server 300 shown in FIG. 1, and the shared server 300 stores all operation functions that the diagnostic device may perform and operation paths corresponding to the operation functions.

After the diagnostic device obtains the function execution instruction of the car diagnosis, it may send an operation path query instruction to the shared server to request the shared server to query the target operation path corresponding to the target function among all shared operation paths. For example, the operation path query instruction sent by the diagnostic device to the shared server instructs the shared server to query the target operation path corresponding to the target function "read the fault code of the engine system from the car system" from all the operation paths shared.

For the shared server, after receiving the operation path query instruction sent by the diagnostic device, it queries the target operation path “System Selection → Engine System → Read DTC” from all operation paths stored in itself.

In another embodiment, all shared operation paths may also be stored in other storage devices, such as the diagnostic device 200 shown in FIG. 3.

FIG. 3 is a schematic diagram of a car diagnostic system according to another exemplary embodiment. As shown in FIG. 3, the diagnosis devices 200 establish a communication connection with each other to share respective stored data. The neighboring diagnostic device 200 queries the target operation path corresponding to the target function. Therefore, this embodiment does not limit storing all the operation paths shared in the sharing server shown in FIG. 1.

In step 250, the target operation path obtained by the query automatically performs the target function on the diagnostic car.

As mentioned before, if the shared server or other storage device queries the target operation path, it sends the queried target operation path to the diagnostic device.

After receiving the target operation path, the diagnostic device enters the vehicle system according to the target operation path, and then performs data interaction with the diagnostic car according to the target operation path to automatically perform the target function on the diagnostic car.

For example, if the searched target operation path is “System Selection → Engine System → Read DTC”, the diagnostic equipment first enters the main system of the diagnosis car according to the target operation path, then enters the engine system under the main system of the car, and then Read the fault code in the engine system to complete the automatic execution of the target function.

In this embodiment, all the diagnosis devices can query the target operation paths corresponding to the respective target functions from all the shared operation paths, so that the diagnostic car automatically executes the corresponding target functions according to the queried target operation paths. If you need to add the operation function of the diagnostic equipment or modify the execution function of the car system, you can store the added or modified operation path in this shared operation path for all diagnostic equipment to obtain, so there is no need to The diagnostic software on the diagnostic device can be re-updated to enable the diagnostic device to obtain the added or modified operation path. Therefore, the diagnosis device can conveniently and quickly obtain a target operation path corresponding to the target function from the shared operation path, and thus automatically perform a diagnosis operation on the diagnosis car according to the acquired target operation path.

FIG. 4 is a flowchart illustrating a method for implementing step 230 in FIG. 2 according to an exemplary embodiment. As shown in FIG. 4, the implementation method may include the following steps:

In step 231, the device information of the diagnostic car and the target function instructed to be executed are acquired from the function execution instruction.

Among them, since the operation paths of diagnostic vehicles of different models under the same function execution instruction may be different, this embodiment needs to acquire the device information of the target diagnostic vehicle and instruct the diagnostic device to execute the target function from the function execution instruction in order to obtain Device information and target function query corresponding target operation path.

Therefore, in this embodiment, the function execution instruction includes, in addition to instructing the target function performed by the diagnostic device, device information of the target diagnostic car corresponding to the target function to be performed by the diagnostic device.

The device information of the target diagnosis car is automatically obtained by the diagnosis device from the target diagnosis car. In one embodiment, the diagnosis device automatically obtains VIN (Vehicle Identification Number) information of the target diagnosis car to diagnose the car according to the target The VIN information can be used to obtain information about the brand model, model, model, displacement, gearbox and other equipment of the target diagnostic car.

In step 233, according to the device information and the target function, all shared operation paths are queried for the target operation path that matches the device information and the target function.

Correspondingly, in this embodiment, the shared server or other storage device not only stores the operation paths corresponding to all the operation functions, but also stores the device information of the diagnostic car corresponding to the operation functions and the operation paths.

Therefore, after the diagnostic device obtains the device information of the target function and the target diagnostic car according to the function execution instruction, it queries the target operation paths that are commonly matched with the device information and target function of the target diagnostic car from all shared operation paths.

In this embodiment, the query of the target operation path by the diagnostic device is performed through the device information and target function of the target diagnostic car. The target operation path queried in this way is more accurate, so that the diagnostic device accurately and automatically Perform the target function.

In another exemplary embodiment, the above-mentioned automobile diagnostic method may further include the following steps:

If a target operation path corresponding to the target function is not queried in all shared operation paths, a prompt message is generated to indicate that the target operation path is not queried.

The shared server or other storage device queries the target operation path according to the operation path query instruction sent by the diagnosis device. If the target operation path cannot be found, a prompt value, such as "0", is returned to the diagnosis device.

After receiving the prompt value, the diagnostic device generates corresponding prompt information to prompt the user that the target operation path is not queried. For example, the diagnostic device generates a prompt text "This operation path has not been queried", and displays the generated prompt text in the car diagnostic interface corresponding to the diagnostic software. Alternatively, after receiving the prompt value, the diagnostic device may also generate a control command to control the prompt device configured by the diagnostic device to perform a corresponding working state, for example, control the flashing of the prompt lamp configured by the diagnostic device, or control the continuous vibration of the diagnostic device.

Therefore, in this implementation, by generating prompt information, the user is informed that the diagnostic device fails to query the target operation path, so as to prompt the user to manually input the operation path information corresponding to the target function on the car diagnosis interface.

It should be noted that the shared server or other storage device can also directly return the prompt message "This operation path has not been queried." The diagnostic device directly displays the received prompt information on the car diagnostic interface, thereby prompting the user to know that the target has not been found Operation path.

FIG. 5 is a flowchart of a method for car diagnosis shown in another exemplary embodiment. As shown in FIG. 5, the method may further include the following steps:

In step 310, operation path information input in a car diagnostic interface is obtained, and the operation path information corresponds to the target function.

Among them, after the user knows that the diagnostic device does not query the target operation path, the user triggers an “operation path input” operation portal added to the diagnostic software interface, and manually inputs the operation path information corresponding to the target function.

For example, if the diagnostic device does not query the target operation path corresponding to the target function "Read the fault code of the transmitter system from the vehicle system", the user can click the "operation path input" operation entry in the diagnostic software interface to enter Target operation path configuration menu, then select the "System selection" menu under the operation path configuration menu, then select the "Engine system" menu under the "System selection menu", and finally select the "Read DTC" menu under the "Engine system" menu To complete the configuration of the target operation path "System Selection → Engine System → Read DTC".

In the process of configuring the target operation path, the information entered in the diagnostic software interface is the operation path information entered in the car diagnostic interface.

In step 330, the operation path information corresponding to the target function is shared.

The diagnosis device shares the operation path information corresponding to the target function manually input by the user, so that other diagnosis devices can query the operation path corresponding to the target function.

In an exemplary embodiment, as shown in FIG. 6, the operation path information corresponding to the target function shared by the diagnosis device may include the following steps:

In step 331, the operation path information and the target function corresponding to the target function are uploaded to a data sharing center, and the data sharing center is used to share all operation paths.

The data sharing center is used to share all operation paths, and the data sharing center may be the foregoing sharing server or other storage device. After the diagnosis device obtains the operation path information input by the user, it uploads the operation path information and the corresponding target function to a shared server or other storage device.

In step 333, the data sharing center is requested to associate the operation path information with the target function.

The diagnostic device requests the data sharing center to store the uploaded operation path information with the corresponding target function, so that the data sharing center can query the corresponding operation path according to the target function.

For the data sharing center, after receiving the operation path information and the corresponding target function sent by the diagnostic device, the target function and the operation path information are correspondingly stored according to the existing relationship in the database, and the diagnostic device can be uploaded. Operation path information is added as a shared operation path.

In another embodiment, the diagnostic device further uploads the device information of the diagnostic car corresponding to the target function to the data sharing center, so that the data sharing center performs the target function sent by the diagnostic device, the device information corresponding to the diagnostic car, and the operation path information. Associative storage, so that the diagnostic device can query the corresponding target operation path according to the target function and the device information of the diagnostic car. In this embodiment, if there is no target operation path currently sought by the diagnostic device among all the shared operation paths, the target operation path corresponding to the target function manually entered by the user is obtained and shared, so that other diagnostic devices thereafter can be shared from Query all target operation paths of this target operation path.
