Integrated diagnosis platform of automobile electric control unit (ECU) and using method of platform

Abstract

The invention relates to an integrated diagnosis platform of an automobile ECU and a using method of the platform, and belongs to the technical field of automobile electric-control diagnosis. The platform comprises a diagnosis standard configuration tool, an offline detection system, an offline detection management system, an ECU after-sale diagnosis system, an after-sale management system, a piece of middleware and a basic database of the after-sale diagnosis system and the offline detection system, wherein the diagnosis standard configuration tool generates an automobile parameter database; the offline detection system is used to detect electric control performances of automobile; the offline detection management system configures, inquires, counts and analyzes the offline detection system; the ECU after-sale diagnosis system diagnoses automobile faults; the after-sale management system configures, inquires, counts and analyzes the ECU after-sale diagnosis system, the middleware synchronizes data of the offline detection management system and the after-sale management system regularly; and the basis database provides unified data support for the offline detection system, the offline detection management system, the ECU after-sale diagnosis system and the after-sale management system.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic control diagnosis, and in particular relates to an integrated platform for diagnosis of automobile electronic control modules and a use method thereof. Background technique [0002] With the development of science and technology, electronic control technology plays an increasingly important role in automobile production. At the same time, the structure of automobile electronic control system is becoming more and more complex. The parts also become more and more difficult correspondingly. According to statistics in the vehicle technical support, the time spent in finding faults accounts for about 70% of the total maintenance time, while the time for troubleshooting and maintenance only accounts for 20% of the total maintenance time. 30%. [0003] In response to this situation, a corresponding fault self-diagnosis system was added during the development of the electronic control unit,...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an integrated diagnostic platform for automotive electronic control modules, aiming to solve the problem that the existing electronic control module on-board diagnostic system, offline diagnostic system and off-line detection system are relatively independently developed, resulting in repeated development of the system
