Abstract

The invention provides an automobile remote diagnostic system and method, wherein the system comprises a vehicle terminal, a remote diagnostic center and a client. The vehicle terminal comprises a microprocessor for controlling acquisition, storage and transmission of automobile diagnosis original data; a collection module in connection with the microprocessor and collecting the automobile diagnosis original data; a 3G communication module in connection with the microprocessor, and remotely transmitting collected automobile diagnosis original data; and a storage module in connection with the microprocessor, and storing the collected automobile diagnosis original data. The remote diagnostic center is used for remotely receiving and managing the automobile diagnosis original data of a vehicle terminal. The client is used for accessing to the automobile diagnosis original data. A remote diagnosis monitoring system of the prior arts has low sampling frequency and less sampling signals, and data can not be returned to a server timely; the automobile remote diagnostic system and method of the invention solve the problems.

Description

technical field [0001] The invention relates to the technical field of automobile remote diagnosis, in particular to an automobile remote diagnosis system and method. Background technique [0002] The degree of electronic control of automobiles is regarded as an important symbol to measure the level of modern automobiles, and the higher the degree of electronic control, the more difficult it is to diagnose automobile faults. Statistics show that the current fault diagnosis time is about 70%, and the troubleshooting time is only 30%. %. With the rapid development of satellite positioning technology, car positioning and navigation can be widely used. At the same time, the popularization of remote communication technology, the Internet and the application of CAN (Controller Area Network) diagnostic technology in the automotive industry have enabled remote diagnostics of vehicles to be realized. [0003] In-vehicle information services, including online entertainment functions...
