Automobile fault diagnosis method and system

Abstract

An automobile fault diagnosis method comprises the following steps that S1) a detector is connected to an automobile via an OBD port, an electric control system of the automobile is detected, electriccontrol characteristic data is obtained, and after detection, equipment detection data is uploaded to a server automatically; S2) the automobile is detected manually to obtain mechanical characteristic data, data is input to a collection terminal, and the manual detection data is uploaded to the server; S3) the server integrates the equipment detection data in the step S1) with the manual detection data in the step S2) to generate detection data with both electric control and mechanical characteristics, and a detection result with a fault problem is obtained; and S4) according to the detection result obtained in the step S3), an intelligent recommended project is output by big data computing and artificial recommendation. The method supports equipment detection and manual detection, result data of detection equipment and manual mechanical detection is integrated, and the recommended projection is generated. The invention also provides an automobile fault diagnosis system.

Description

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

Problems solved by technology

[0004] The existing detection methods mainly have the following problems: equipment detection and manual detection are two independent detection methods, equipment detection data and manual detection data are also two independent detection data, which cannot be integrated, and there is no targeted solution to the fault problem Solutions and Recommended Items
