detailed description

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, device, electronic device, and storage medium 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 Figure 1, the method is applied to the vehicle to be diagnosed, and the method includes the following steps:

Step 101, receiving a remote control command sent by a server, the remote control command 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, searching for the target test script, and executing 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 the target test script is determined, 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 , diagnosing 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 possible solution of the embodiment of the present application, the target test script also includes the user interface display information and operation feedback information of the vehicle to be diagnosed, and the 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 user interface HMI operation interface of the vehicle to be diagnosed to realize the display of the Human Machine Interface (HMI) and the cloud terminal in the vehicle, so that the user can view it.

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

As a refinement of the above-mentioned embodiment, in step 103, performing diagnosis on the execution result of the target test script based on the preset diagnosis engine Diag Agent includes: acquiring The signal variable is called, and the preset communication interface is called to obtain a diagnosis database, and the signal variable is diagnosed based on the diagnosis database, and the diagnostic failure result corresponding to the signal variable is obtained.

The target test script contains numerical calculations, logic, decision and loop related operations related to diagnostic variables and bus variables. The diagnostic engine shall be able to parse test sequence scripts and implement operations. The preset 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 this 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. If 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, as an example, assume that the target test script is to detect car lights. When the preset diagnosis engine executes the target test script, it calls and controls the operation of the car lights. For example, when the car lights are triggered to turn left, the 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, if the car light is not faulty, signal after triggering The variable should be left-1, right-0. After the step of controlling the lights is executed, the signal variable is detected to be changed, and the signal variable is diagnosed based on the diagnosis database to obtain the failure status of the lights. diagnostic result. 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 application does not limit the specific content of the target test script and the diagnostic database.

The embodiment of the present application also provides a remote diagnosis method, as shown in Figure 2, the method also includes:

Step 201, receiving condition information configured and sent by the server for executing the test script.

Each test script execution sequence shall contain condition information before execution, and the content of the condition information is usually defined by bus variables or diagnostic variables. The preset diagnostic engine Diag Agent should first invoke 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 application 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.

If the condition information is satisfied, step 203 is performed, and if the condition information is not satisfied, step 204 is performed.

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 descriptions of the above 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 a 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. If the status information item is the status information item of the vehicle, such as the vehicle power mode, gear position, etc. 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 , diagnosing 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 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 data record file information of the test script execution process, 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, receiving the real-time or periodic remote update of the test script in the local script library 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 period is set to 5 days, etc. The embodiment of the present application does not limit the method of updating.

To sum up, compared with the related technologies, the embodiment of the present application can reduce the time for checking and locating vehicle faults through the introduction of target diagnostic scripts, thereby improving maintenance efficiency. In addition, based on the preset diagnostic engine DiagAgent based on the vehicle to be diagnosed, the server The diagnostic sequence of the test script of Diag Agent, the preset diagnostic engine at the vehicle end, can be updated in real time to realize the upgrade of diagnostic functions of different vehicle platforms and different controllers. In addition, based on the vehicle data of the vehicle to be diagnosed, the active diagnosis of the vehicle to be diagnosed can be carried out. When there is a problem with the vehicle, the user is reminded to maintain it, or when parts need to be replaced, the replacement parts can be prepared in advance, further reducing maintenance. waiting time.
