Vehicle fault diagnosis method, system and intelligent diagnosis server side thereof

Abstract

The invention discloses a vehicle fault diagnosis method. The method comprises the following steps of: acquiring a reference fault processing method and updating an expert diagnosis database. The acquisition of the reference fault processing method comprises the following steps of: acquiring reference fault reasons and the reference fault processing method according to the fault information, the real-time vehicle information and the expert diagnosis database; and sending the fault information, the real-time vehicle information, the reference fault reasons and the reference fault processing method to a client. The update of the expert diagnosis database comprises the following steps of: adding actual fault reasons and an actual fault processing method to the reference fault reasons and thereference fault processing method. The invention further provides a vehicle fault diagnosis system. The system comprises an on-board intelligent terminal, an intelligent diagnosis server side and theclient. The invention also provides an intelligent diagnosis server side for the system. According to the method, system and the intelligent diagnosis server, the technical problems are solved that the current vehicle fault diagnosis result is not accurate enough and the database is not perfect.

Description

technical field [0001] The invention belongs to the technical field of vehicle fault diagnosis, and more specifically relates to a vehicle fault diagnosis method, system and intelligent diagnosis server end thereof.
