Abstract

The invention discloses a method, device and system for achieving vehicle diagnosis and belongs to the technical field of intelligent terminals. The method comprises the steps of determining a link layer protocol entering a vehicle ECU through roll polling of each ODB link layer protocol, receiving and analyzing a diagnosis command sent by an intelligent terminal, acquiring a diagnosis result from the vehicle ECU through the link layer protocol according to the diagnosis command and analyzing the diagnosis result, and sending the analyzed diagnosis result to an intelligent terminal through a Bluetooth communication module. According to the method, device and system for achieving vehicle diagnosis, diagnosis of vehicle failures is achieved through the intelligent terminal, and as a result, diagnosis of the vehicle failures can be achieved more quickly and conveniently for a user, intelligentization and convenience of a vehicle are improved, and time cost and economic cost are saved for the user.

Description

technical field [0001] The invention belongs to the technical field of intelligent terminals, and more specifically relates to a method, device and system for realizing automobile diagnosis. Background technique [0002] In today's society, cars are becoming more and more popular and become an indispensable means of transportation in people's family life. More and more individual users hope that they have a car diagnostic tool that is easy to carry and easy to operate, and can be used for their own cars. Real-time detection and preliminary positioning of vehicle faults to improve the performance and intelligence of the vehicle. At present, the popular automotive diagnostic tools on the market are all wired connections, which integrate the operation interface and diagnostic functions into one diagnostic device, which makes the diagnostic device not only bulky, but also expensive and ugly in interface, so it is only suitable for special-purpose car repairs. factory.
