The set diagnosis parameters can also be determined according to specific application scenarios, for example, for a failure that the vehicle cannot run, the determinable set diagnosis parameters can be parameters such as tire pressure of the tire, tire internal temperature, vehicle speed, and the like. The set data uploading period is an automatic uploading period of target data of an electronic control unit of the vehicle system. The set data upload period may be preset by a development engineer according to a failure, and for example, it may be set to upload target data in the electronic control unit once every five minutes. And the intelligent terminal is provided with a diagnostic file development tool, and the diagnostic file development tool is used for generating a diagnostic file corresponding to the vehicle system according to the set diagnostic parameters and the set data uploading period.

Wherein, the diagnosis file is also called ODX file, and the file format of the ODX file is XML format. ODX is called Open diagnostic data exchange, which is a data file used by a standard architecture diagnostic equipment (MVCI) made by ASAM.

The internet of vehicles background terminal is a TSP platform; the remote control terminal is a T-BOX, and the T-BOX is equivalent to a wireless intelligent terminal and is used for analyzing the diagnostic file and forwarding the diagnostic file to an electronic control unit. The electronic control unit is an ECU, the electronic control unit stores vehicle running data, and target data corresponding to set diagnosis parameters can be acquired from the electronic control unit. The set diagnostic parameter may be sent only in the form of the specific parameter being acquired, such as acquiring temperature. Alternatively, the set diagnostic parameter may be sent in the form of a parameter condition, for example, the set diagnostic parameter may be: acquiring data with the temperature of more than 50 ℃; it is also possible to obtain data for a certain period of time, for example, data for a temperature greater than 50 ℃ during the period of time from 2021 year-12 month-14 morning from 9:00 to 12:00, etc.
Optionally, verification information of the vehicle system may be further set in the diagnostic file, so that the electronic control unit verifies the verification information of the vehicle system, and when the verification is successful, filters the target data according to the set diagnostic parameters in the diagnostic file.
In this embodiment, after the target data is screened in the vehicle system, the target data is automatically uploaded to the intelligent terminal in the form of a data message according to a set data uploading period. After receiving target data fed back by a vehicle system, the intelligent terminal can specifically analyze the target data, so that fault information of the vehicle system can be diagnosed according to the target data. The process of the specific analysis is not discussed herein.
Optionally, when the fault location is successful, the default diagnostic file is restored, that is, the report of leaving the factory is restored, and only the data of the regulations is uploaded, so that the vehicle information is prevented from being excessively collected.
According to the technical scheme, the diagnostic file corresponding to the vehicle system is generated according to the set diagnostic parameters and the set data uploading period; the diagnostic file is sent to a vehicle system, wherein after the vehicle system receives the diagnostic file sent by the intelligent terminal, target data are screened according to set diagnostic parameters in the diagnostic file, and the target data are uploaded to the intelligent terminal according to the set data uploading period in the diagnostic file; the technical scheme of receiving the target data fed back by the vehicle system and diagnosing the fault information of the vehicle system according to the target data solves the problem that the vehicle fault cannot be positioned and reproduced.
