As shown in FIG. 1 , in the first embodiment of the present invention, the vehicle data acquisition method of the present invention includes the following steps:

Step S110, generating a diagnostic file corresponding to the vehicle system according to the set diagnostic parameters and the set data upload period;

Step S120, sending the diagnosis file to the vehicle system, wherein after receiving the diagnosis file sent by the intelligent terminal, the vehicle system filters the target data according to the set diagnosis parameters in the diagnosis file, and selects the target data according to the diagnosis file. The set data upload cycle in the diagnostic file uploads the target data to the smart terminal;

Step S130: Receive the target data fed back by the vehicle system, so as to diagnose fault information of the vehicle system according to the target data.

In this embodiment, in order to solve the problem that the failure information cannot be reproduced and located when the vehicle fails. The present invention designs a method for acquiring vehicle data. In this embodiment, the method for acquiring vehicle data is applied to an intelligent terminal. The intelligent terminal determines a diagnosis file according to the failure of the vehicle system in the market, sends the diagnosis file to the vehicle system to obtain corresponding target data, and diagnoses the failure information of the vehicle system according to the target data.

In this embodiment, the set diagnostic parameters may be preliminarily set according to faults pre-collected by the market, and the faults may be feedback from users or determined in the process of research and development testing. The set diagnostic parameters can also be determined according to specific application scenarios. For example, for a fault that the vehicle cannot be driven, the set diagnostic parameters that can be determined may be parameters such as tire pressure, tire internal temperature, and vehicle speed. The set data upload cycle is an automatic upload cycle of target data of the electronic control unit of the vehicle system. The set data upload period can be preset by the development engineer according to the fault. For example, the target data in the electronic control unit can be set to be uploaded every five minutes. A diagnostic file development tool is installed on the intelligent terminal, and the diagnostic file development tool is used to generate a diagnostic file corresponding to the vehicle system according to the set diagnostic parameters and the set data upload period.

Specifically, in the process of generating the diagnostic file corresponding to the vehicle system according to the set diagnostic parameters and the set data upload period, a preset diagnostic file template corresponding to the vehicle signal of the current vehicle system determined by the diagnostic file development tool is obtained, and the The acquired set diagnostic parameters and the set data upload period are written into the preset diagnostic file template, thereby generating a diagnostic file corresponding to the vehicle system. Wherein, the diagnosis file is also called an ODX file, and the file format of the ODX file is an XML format. The full name of ODX is Open diagnostic data exchange, which is the data file used by the standard architecture diagnostic instrument (MVCI, Modular Vehicle Communication Interface) developed by ASAM. The ODX file is a diagnostic file with a standardized format, and the diagnostic file can diagnose different models of cars, or different vehicle systems only need to load the ODX file adapted to the model, without any changes to the diagnostic instrument. And ODX unifies the format of the diagnostic file, so when the diagnostic file is transferred and exchanged in R&D, testing, production, after-sales and other departments, no format conversion is required.

updating the diagnostic file according to the modified diagnostic parameters and/or the modified data uploading period;

and returning to the step of sending the diagnosis file to the vehicle system.

4. The vehicle data acquisition method according to claim 3, wherein after the step of receiving the target data fed back by the vehicle system to determine the failure information of the vehicle system based on the target data, the method further comprises:

analyzing fault information of the vehicle system according to the target data;

when the fault reason of the vehicle is determined to be a preset fault reason according to the fault information, updating the diagnostic file by adopting initial diagnostic parameters and an initial data uploading cycle;

and when the vehicle fault reason is determined not to be the preset fault reason according to the fault information, executing the step of acquiring the modified diagnosis parameters and/or the modified data uploading period according to the modification request when the diagnosis parameter modification request is received.

5. The method for acquiring the vehicle data is characterized by being applied to a vehicle system; the vehicle data acquisition method comprises the following steps:

receiving a diagnosis file sent by an intelligent terminal, wherein the diagnosis file comprises set diagnosis parameters and a set data uploading period;

screening target data according to set diagnosis parameters in the diagnosis file;

and uploading the target data to the intelligent terminal according to the set data uploading period in the diagnosis file.

6. The vehicle data acquisition method according to claim 5, wherein the diagnostic file further includes authentication information of a vehicle system; before the step of screening the target data according to the set diagnosis parameters in the diagnosis file, the method further comprises the following steps:

performing authority verification on verification information of the vehicle system in the diagnosis file;

and when the authority verification of the vehicle system is successful, the step of screening target data according to the set diagnosis parameters in the diagnosis file is executed.

7. The vehicle data acquisition method according to claim 5, wherein the step of uploading the target data to the intelligent terminal according to the data upload period in the diagnostic file comprises:

carrying out format conversion on the target data based on a preset data format;

packing the target data after format conversion;

and uploading the packed target data to the intelligent terminal according to the data uploading period in the diagnosis file.

8. An intelligent terminal, characterized in that, intelligent terminal includes: memory, a processor and a vehicle data acquisition program stored on the memory and executable on the processor, the vehicle data acquisition program, when executed by the processor, implementing the steps of the vehicle data acquisition method according to any one of claims 1 to 4.

9. An intelligent terminal, characterized in that, intelligent terminal includes:

the generating module is used for generating a diagnostic file corresponding to the vehicle system according to the set diagnostic parameters and the set data uploading period;

the sending module is used for sending the diagnosis file to a vehicle system, wherein the vehicle system screens target data according to set diagnosis parameters in the diagnosis file after receiving the diagnosis file sent by the intelligent terminal, and uploads the target data to the intelligent terminal according to the set data uploading period in the diagnosis file;
