A method and system for remote vehicle-mounted fault troubleshooting and repair

Abstract

The invention discloses a method and system for remote on-board troubleshooting and repair. When a vehicle malfunction alarms, it is confirmed whether to enter the troubleshooting mode; after entering the troubleshooting mode, when the vehicle is in a safe environment, it enters the set troubleshooting work At the same time, according to the current fault information, the working condition data of the corresponding system on the vehicle is collected; after the fault troubleshooting is completed, combined with the working condition data, fault maintenance suggestions are given remotely, and on-site fault repairs are carried out according to the maintenance suggestions. The remote fault diagnosis method of the present invention is more direct and efficient. The corresponding acquisition module is awakened according to the fault code information, which greatly reduces the data flow, and prompts the driver to enter a specific fault reproduction working condition, which can quickly find problems, reduce the amount of data, and effectively avoid data redundancy. Residual and data loss risks, to achieve the purpose of rapid troubleshooting and analysis of faults.

Description

technical field [0001] The invention belongs to the technical field of on-line diagnosis of automobile engines, and in particular relates to a method and system for remote on-board troubleshooting and repair. Background technique [0002] Cars have become an indispensable tool for people to travel. At the same time, users' requirements for the safety and comfort of cars are also increasing. However, vehicles will inevitably break down during use. In order to ensure their safety, once If a fault occurs, the cause should be found out and dealt with in time. Under normal circumstances, when a vehicle breaks down, for some customers, they can go to a 4S shop or an auto repair shop for repairs and maintenance in time, but for customers in remote areas, it is difficult to guarantee the timeliness of this troubleshooting, and some Faults often need to be detected by professional technical means, and the driver cannot obtain vehicle condition information in time, which will cause a...

Problems solved by technology

[0004] The first method is to connect the OBD-II interface of the vehicle to the OBD-II interface of the vehicle through the 4S shop’s proprietary car diagnosis and testing equipment. status, basic information of the vehicle, for systemic faults, it is still impossible to accurately locate the faulty parts, accurately and efficiently lock the faults, and point out the faulty parts; It is difficult for maintenance personnel to carry out correct and effective maintenance in the face of complex vehicle failures. In this case, it is necessary for the automobile manufacturer to send a professional technical team to the site for support, which will undoubtedly increase the developer's work cycle and travel expenses. The overall longer after-sales service can also cause strong complaints from customers

[0005] The second method is to install a dedicated monitoring module to collect data in real time. This solution can collect vehicle condition information very well, breaking through the limitations of the location and time of the diagnostic approach through proprietary equipment. Higher requirements are put forward in all aspects, because the large amount of data flow information generated by real-time collection is difficult to store for a long time, the cost is high, and there is currently a lack of a comprehensive large-scale diagnostic database to participate in the analysis of a large amount of data and all diagnoses
