A method and system for vehicle fault diagnosis

Abstract

The present invention is a method for fault diagnosis of automobiles, comprising the following steps: S1: the detection equipment connects to the vehicle through the OBD port, detects the electric control system of the vehicle, obtains the electric control characteristic data, and automatically uploads the detection data of the equipment after the detection is completed to the server; S2: Manually detect the vehicle to obtain mechanical characteristic data, input the data acquisition terminal, and upload the manual detection data to the server; S3: The server performs a process on the equipment detection data in step S1 and the manual detection data in step S2 Integrate and generate detection data including electrical control characteristics and mechanical characteristics, and obtain detection results including fault problems; S4: According to the detection results obtained in step S3, output intelligent recommendation items through big data calculation and manual recommendation. This method supports equipment inspection and manual inspection, and connects the result data of inspection equipment and manual mechanical inspection to generate recommended items. The invention also proposes a system for automobile fault diagnosis.

Description

technical field [0001] The invention relates to a method for automobile fault diagnosis, belonging to the technical field of automobile diagnosis and detection. Background technique [0002] With the development of my country's economy, the living standards of the people have been greatly improved. As a durable consumer product, automobiles are increasingly entering the homes of ordinary consumers. According to the statistics of the Ministry of Public Security, as of the end of 2018, the number of motor vehicles in the country has been More than 327 million, with the huge car stock comes the motor vehicle maintenance and testing business, and the market is also huge. [0003] At present, when the automobile is inspected, there are generally two methods for the diagnosis and inspection of the car: equipment inspection and manual inspection. Equipment detection and diagnosis are generally connected to the car through the OBD interface, and then test the electronic control syst...
