Automobile fault diagnosis and monitoring system and method based on IVI host

Abstract

The invention belongs to the technical field of automobile electronics, and relates to an automobile fault diagnosis and monitoring system and method based on an IVI host. The system comprises an IVIhost, a controller, a gateway, a TBOX and a cloud server. The IVI host is connected with the controller through the gateway and a bus; the IVI host is connected with the TBOX through a USB or an Ethernet. The TBOX sends information to the cloud server through a 4G or 5G network; the cloud server stores a fault diagnosis process and deploys a remote fault diagnosis system; fault diagnosis, data monitoring and fault early warning of the controller are realized through the IVI host; a fault code and a fault analysis code are displayed through a central control display screen; automobile running parameters are displayed in a data stream or graphical form through the central control display screen; an expert system of the cloud server judges the automobile running state according to the automobile real-time running data and the fault code; fault diagnosis query is realized through a human-computer interaction interface of the central control display screen, and fault code reading or vehiclerunning state monitoring can be realized without special diagnosis equipment.

Description

Technical field[0001]The invention belongs to the technical field of automobile electronics, and relates to an automobile fault diagnosis and monitoring system and method based on an IVI host.Background technique[0002]Vehicle fault diagnosis refers to the process of determining the scope of the fault and finding the true cause of the fault by checking and judging the fault of the vehicle when the vehicle is faulty or when the fault is characterized. With the development of automobile technology, the means of automobile fault diagnosis also continue to develop.[0003]The early structure of the automobile was simple and mainly mechanical structure. At this time, the fault diagnosis method was mainly manual diagnosis, and the accuracy of the diagnosis could not be guaranteed. As the vehicle structure became more and more complex, the vehicle fault diagnosis gradually introduced general equipment, such as various scales. The introduction of general equipment, such as oscilloscopes, quant...
