Automobile diagnostic method, system, diagnostic terminal and backstage server

Abstract

The invention belongs to the field of automobiles, and in particular discloses an automobile diagnostic method, a system, a diagnostic terminal and a backstage server, so that an automobile owner is enabled to master the fault situation of the automobile in real time. The method comprises the step of installing the diagnostic terminal in the automobile to be connected with an electronic control unit (ECU) so as to obtain state data of the automobile in the ECU; detecting whether the automobile has faults according to the obtained state data; when the automobile has faults, generating a fault code and transmitting the fault code in real time; and transmitting the diagnosis result obtained by diagnosing and analyzing the fault code to the automobile owner. The diagnostic terminal comprises an interface, an obtaining module, a detection nodule, a fault code generating module and a transmitting module, wherein the interface is used for being connected with the ECU in the automobile; the obtaining module is used for obtaining the state data of the automobile in the ECU; the detection module is used for detecting whether the automobile has faults according to the obtained state data; the fault code generating module is used for generating a fault code when the automobile has faults; and the transmitting module is used for transmitting the fault code in real time so as to diagnose and analyze the fault code.

Description

technical field [0001] The invention relates to the field of the Internet, and in particular, to a vehicle diagnosis method, a system, a diagnosis terminal and a background server. Background technique [0002] Car diagnosis refers to the inspection of various parts of the car without dismantling the car (or only removing individual parts), and analyzing the cause of the failure when a faulty part is detected; for example, the detection and diagnosis of the car engine , the detection and diagnosis of automobile body and accessories, as well as the detection and diagnosis of automobile exhaust pollutants and noise. [0003] The traditional car diagnosis methods include: the electronic control unit (ECU) installed in the car generally has a fault diagnosis function to detect the working status of each part of the car; when a fault is detected in a certain part of the car, a fault is generated according to the type of fault. The fault code is stored in the random access memory...

AI Technical Summary

Problems solved by technology

[0004] However, although the traditional automobile diagnosis method can perform daily detection on the working status of the various parts of the automobile, it is impossible for the car owner to know the fault situation of the car in real time; if the car owner needs to know the fault situation, he needs to drive the car The clear diagnostic information can only be obtained from the car service agency, and the car owner can decide whether to repair the car based on the diagnostic information

Because the car owner cannot know the fault situation of the car in real time, he will not take the initiative to drive the car to the car service agency for fault diagnosis under normal circumstances; When the car is in use, the owner will send the car to the car service agency for diagnosis, which will cause hidden dangers to driving safety and vehicle maintenance
