Abstract

The invention discloses a diagnostic method for a vehicle condition, and belongs to the field of automobile fault diagnosis. The method comprises that: a vehicle condition diagnosis and analysis model of a remote diagnostic center is built; Bluetooth connection between a terminal of a vehicle and on-board diagnostics-II (OBD-II) is built, OBD-II vehicle data are collected; the terminal sends the collected vehicle data according to a preset frequency to the remote diagnostic center through general packet radio service (GPRS); the remote diagnostic center is based on the vehicle data and the diagnosis and analysis model, according to the choice of a user, the vehicle condition is diagnosed according to an instant diagnostic mode or a month diagnostic mode. The diagnostic method for the vehicle condition solves the problems that the prior diagnostic method relies on professional equipment, diagnostic data are limited, and comprehensive diagnosis data banks are lacking.

Description

technical field [0001] The invention relates to the technical field of automobile fault diagnosis, in particular to a method for diagnosing and analyzing vehicle conditions through wireless access. Background technique [0002] With the development of the automobile industry and the continuous integration of various technologies such as modern electronic technology, communication technology, and network technology, the structure of automobiles has become more and more complex and the degree of automation is getting higher and higher. At the same time, users' requirements for the safety and comfort of automobiles are also increasing day by day. One of the important requirements is to be able to grasp the running status of the vehicle in a timely and accurate manner, so as to find and eliminate hidden troubles as soon as possible. [0003] On-Board Diagnostics (OBD) was first used by General Motors (GM) to monitor the emission control system. Once a fault is found, the OBD sy...
