Abstract

The invention relates to a method and system for remote intelligent diagnosis of automobiles based on a knowledge base. The method includes the following steps: constructing a vehicle health examination model; collecting data streams of the current vehicle; substituting the data stream of the current vehicle into the vehicle health examination model to obtain the current vehicle Health examination report; the system includes a vehicle health examination model building module for building a vehicle health examination model; the current vehicle data flow acquisition module is used to collect the current vehicle data flow; the current vehicle health examination report generation module is used to use the current vehicle data flow Substituting the flow into the vehicle health examination model to obtain the current vehicle health examination report. The invention can solve the problems of automobile failure and risk response lag and excessive reliance on maintenance personnel, conduct predictive abnormal diagnosis through data flow, and conduct intelligent computer analysis through vehicle health examination model to accurately find the cause of the problem.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a knowledge base-based remote intelligent diagnosis method and system for automobiles. Background technique [0002] At present, the application of the Internet of Vehicles is gradually deepening. With the installation of rear-installed OBD equipment and front-installed integrated equipment on automobiles, more and more vehicles are included in the scope of full coverage of information. As a comprehensive information service terminal, on the one hand, the car continuously sends the operating data of each subsystem of the vehicle to the remote server, and on the other hand, it obtains various information from the Internet, including news, audio, video, location-based services etc. [0003] At present, many methods for car diagnosis mainly include diagnostic equipment and remote diagnosis system. Diagnostic equipment is generally used for on-site diagnostic and analysis tools ...
