Abstract

The invention provides an automobile fault diagnosis system and method. The system comprises a fault diagnosis tester and a network data server, wherein the fault diagnosis tester is connected with the network data server in a communication mode through a wireless network interface and is used for diagnosing automobile faults and for uploading automobile diagnosis data logs and remote assistance logs to the network data server; the network data server is used for storing the automobile diagnosis data logs, the remote assistance logs and automobile repair material. Through building a mother-son automobile fault diagnosis tester system, by the adoption of the two-stage remote assistance mechanism, the automobile fault diagnosis system and method can reduce the workload of a full-time automobile fault specialist substantially and improve response speed of service, and maintenance cost of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis, in particular to an automobile fault diagnosis system and a diagnosis method thereof. Background technique [0002] With the rapid development of automotive electronic control systems, there are many types of automotive electronic control systems with different functions and characteristics. The use of automotive fault diagnosis equipment is becoming more and more complicated, including the use of some special functions such as ECU flashing and anti-theft, which have certain risks. , often requires remote assistance from experts to complete. [0003] At present, there are mainly two ways to implement remote assistance for automotive diagnostic equipment. One is based on high-performance equipment hardware to realize the remote assistance function between diagnostic equipment. The equipment is connected through a network interface to realize mutual remote assistance. Diagnosis log da...
