Detailed ways

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The remote diagnosis method and device, electronic equipment, storage medium, computer program product, and computer program of the embodiments of the present disclosure are described below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a remote diagnosis method provided by an embodiment of the present disclosure.

As shown in FIG. 1 , the remote diagnosis method is applied to the vehicle to be diagnosed, and the remote diagnosis method includes steps 101-103.

Step 101: Receive a remote control instruction sent by a server, the remote control instruction is used to instruct the vehicle to be diagnosed to execute a target test script.

The timing for the server to send the remote control command can be after the vehicle to be diagnosed sends the request information, or it can be the remote control command sent by the server to the vehicle to be diagnosed actively. Triggering the sending of a remote control command for instructing the vehicle to be diagnosed to execute the target test script.

The target test script is one or at least one of the test scripts. The test script is generated on the server side and sent to the vehicle to be diagnosed, or the vehicle to be diagnosed requests to download the test script and stores the received test script. In the local script database, after receiving the remote control command, from the local script database.

The test script is a scripted description of a diagnostic test sequence execution process (that is, the test script is a test script execution sequence). The description of the limited scripting language can only be lua, and any language can be used to describe the test script as a script. In order to facilitate remote diagnosis, different test scripts (Identity document, ID) can be divided by diagnostic categories. For example, the diagnostic category is full vehicle diagnosis, and its corresponding test script ID is test script 1. The test script ID is test script 2, the diagnostic category is key matching diagnosis, and the corresponding test script ID is test script 3 and so on.

The trigger of remote diagnosis usually comes from the diagnostic business function requirements, which are usually output in docx file format and sent by the offline inspection server or the after-sales diagnosis service server. The task of checking a station for key matching, the corresponding test script is the key matching test script. The function requirement of the diagnosis service is to request the after-sales diagnosis service server to read all the fault codes of a vehicle, and the corresponding test script is the test script of the whole vehicle fault codes, which is usually output in an xlsm format file.

Step 102: Find the target test script, and execute the target test script based on a preset diagnosis engine.

The remote control instruction usually includes a diagnostic category. After the vehicle to be diagnosed receives the remote control instruction, it parses the diagnostic category, and searches the local script database for the target test corresponding to the diagnostic category according to the script ID corresponding to the diagnostic category. script.

After determining the target test script, the test script is analyzed based on the preset diagnosis engine Diag Agent, the test script execution sequence of the test script is obtained, and the target test script is executed. Since the target test script is described using lua script language, Therefore, the corresponding preset diagnosis engine Diag Agent can run the lua script to realize the target test script.

Step 103: Diagnose the execution result of the target test script based on the preset diagnosis engine.

The default diagnosis engine Diag Agent can not only execute the target test script, but also judge the final execution result of the target test script. If the execution succeeds or fails, the execution result and failure reason will be uploaded to the server. In another feasible solution of the embodiment of the present disclosure, the target test script further includes user interface display information and operation feedback information of the vehicle to be diagnosed, and cloud user interface display information and feedback information. The default diagnosis engine Diag Agent should be able to analyze the display requirements of the diagnostic test sequence script, and call the HMI operation interface of the vehicle user interface to be diagnosed to realize the display of the human machine interface (Human Machine Interface, HMI) and cloud terminal in the vehicle, so that the user can view it.

The remote diagnosis method provided by the embodiment of the present disclosure receives a remote control instruction sent by a server, and the remote control instruction is used to instruct the vehicle to be diagnosed to execute a target test script; search for the target test script, and execute it based on a preset diagnosis engine The target test script; performing diagnosis on the execution result of the target test script based on the preset diagnosis engine. Compared with related technologies, the embodiments of the present disclosure can reduce the maintenance waiting time of the vehicle owner when the vehicle fails and improve the maintenance efficiency through remote diagnosis.

In a specific embodiment, performing diagnosis on the execution result of the target test script based on the preset diagnosis engine Diag Agent in step 103 includes: obtaining the signal variable of the preset diagnosis engine when executing the test script and calling a preset communication interface to obtain a diagnosis database, and performing diagnosis on the signal variable based on the diagnosis database, and obtaining a fault diagnosis result corresponding to the signal variable.

The target test script contains related operations such as numerical calculations, logic, decisions and loops related to diagnostic variables and bus variables. The diagnostic engine shall be able to parse test sequence scripts and implement operations. The default diagnosis engine Diag Agent can call the preset communication interface to obtain the diagnosis database during the execution of the target test script. The diagnosis database can realize all the diagnosis of the test script. Assume that the diagnostic engine Diag Agent monitors the change of each signal variable when executing the target test script, that is, after executing one of the steps in the target test script, confirm whether the signal variable in the step changes, before executing the target test script, any A signal will have a default value. After the target test script is executed, the default signal value of the signal variable may change or remain unchanged, but the final execution result must be a fixed value. Based on the execution result of the signal variable If it is not a fixed value, it can be judged that the signal is faulty. Based on the diagnostic database, the diagnostic fault results corresponding to the signal variables can be obtained.

For ease of understanding, in some embodiments, it is assumed that the target test script is to detect vehicle lights. When the preset diagnosis engine executes the target test script, it calls and controls the operation of the vehicle lights. For example, when the vehicle lights turn left, the vehicle lights are activated. Turn right, before triggering: signal variable: left (left car light) -0, right (right car light) -0, after triggering: left-0, right-1, based on the fact that the car light is not faulty, the trigger The final signal variable should be left-1, right-0. After the step of controlling the vehicle light is executed, the signal variable is detected to be changed, and the signal variable is diagnosed based on the diagnosis database to obtain the existence of the vehicle light. Fault diagnosis results. It should be noted that the above example is only a brief example for easy understanding, and does not represent a specific execution process. The embodiment of the present disclosure does not limit the specific content of the target test script and the diagnostic database.

The embodiment of the present disclosure also provides a remote diagnosis method. As shown in FIG. 2 , the remote diagnosis method further includes steps 201-208.

Step 201: Receive condition information for executing the test script configured and sent by the server.

Each test script execution sequence should contain condition information before execution, and the content of condition information is usually defined by bus variables or diagnostic variables. The default diagnostic engine Diag Agent should call the diagnostic check condition information before executing each test script execution sequence, and the diagnostic test sequence can only be executed after the check is successful. The condition information includes state information items that need to be detected in the vehicle to be diagnosed, for example, the vehicle is in maintenance mode, the power mode of the vehicle to be diagnosed is ON or OFF, the gear position is P, the vehicle speed is less than 2km/h, and the default value of the signal variable value, etc., the embodiment of the present disclosure does not limit the content contained in the condition information.

Step 202: Judging whether the condition information is satisfied according to the state information items in the vehicle to be diagnosed.

Due to the differences in different target test scripts, the judgment of the condition information of the test script will be performed before executing each target test script. The purpose is to create conditions for the correct execution of the preset diagnosis engine Diag Agent and avoid An error occurred during the execution of the diagnosis engine Diag Agent.

Since different target test scripts have different corresponding execution condition information, when executing the target test script, it is enough to judge one by one according to the state information items of the current vehicle to be diagnosed.

In response to satisfying the condition information, execute step 203; in response to not satisfying the condition information, execute step 204.

Step 203: Execute the target test script based on the preset diagnosis engine.

Regarding the process of executing the target test script by the preset diagnosis engine Diag Agent, reference may be made to the relevant description of the above-mentioned embodiments, and details will not be repeated here.

Step 204: Report the execution result that the test script cannot be executed to the server, so that the server resets the condition information for executing the test script, so as to complete the remote diagnosis.

When reporting the result that cannot be executed, the status information item that the server carries can be configured, such as the default value of the signal variable, etc., based on the status information item is the status information item of the vehicle, such as the vehicle power mode, gear position, etc., can be based on The condition information of the test script is adjusted, for example, the power mode and gear position of the vehicle to be diagnosed are adjusted according to the condition information.

Step 205: Diagnose the execution result of the target test script based on the preset diagnosis engine.

Regarding the diagnosis of the preset diagnosis engine Diag Agent, reference may be made to the relevant descriptions of the above-mentioned embodiments, and details will not be repeated here.

Step 206: Generate a reporting configuration file according to the diagnosis result, the diagnosis result including at least one of the execution process information of the test script, the execution process data record file information of the test script, and the execution result information of the test script.

The preset diagnosis engine Diag Agent should be able to save and record the diagnostic sending and receiving bus messages related to the execution of this test sequence synchronously according to the same time stamp during the execution of the test script execution sequence, and realize the report according to the storage requirements of the report configuration file defined by the test sequence Configuration file storage and reporting.

Step 207: Upload the reporting configuration file to the server.

Step 208: Receive the real-time or periodic remote update of the test script in the local script repository by the server.

It should be noted that the execution sequence of step 208 is not executed in the order of serial numbers. This update process is a remote update of the server. When there is an update of the test script on the server side, the test script in the vehicle to be diagnosed will be updated synchronously. The method can be updated in real time or periodically, for example, the cycle is set to 5 days, etc., and the embodiment of the present disclosure does not limit the method of updating.

To sum up, compared with the related technologies, the embodiments of the present disclosure can reduce the time for checking and locating vehicle faults through the introduction of target diagnostic scripts, thereby improving maintenance efficiency. In addition, the Diag Agent, a preset diagnostic engine based on the vehicle to be diagnosed, can The server can update the test script diagnosis sequence of Diag Agent, the preset diagnosis engine of the car in real time, to realize the upgrade of the diagnosis function of different vehicle platforms and different controllers.
