Universal bus parallelism-based vehicle diagnosis system and method

Abstract

The invention relates to a universal bus parallelism-based vehicle diagnosis system and a universal bus parallelism-based vehicle diagnosis method. The system comprises an upper computer and a plurality of lower computers connected with the upper computer in parallel through data buses; system software and a plurality pieces of application software with different functions are configured in the upper computer; the upper computer is provided with communication interfaces; the plurality of lower computers are all in electric connection with the communication interfaces through the data buses; the lower computers are a plurality of functional control modules with different functions; different functional control modules correspond to application software with different functions in the upper computer; a data interface is formed in each of the functional control modules; and the functional control modules are respectively connected with diagnosis interfaces of a vehicle to be diagnosed through the respective data interface. The upper computer is in parallel connection with the plurality of the lower computers through USB data buses; and the upper computer is communicated with the lower computers according to the selection of a user and controls the lower computers to finish a vehicle fault diagnosis task, so that the shortage of integrated vehicle fault diagnosis equipment can be overcome, the requirement on diversification is met, and the occasions of large data volume and high speed requirement in a high-level function of vehicle fault diagnosis can be met.

Description

technical field [0001] The present invention relates to a vehicle diagnosis system and method, in particular to a parallel vehicle diagnosis system and method based on a universal bus. Background technique [0002] Automobile is the most familiar and common means of transportation for people, and it plays a very important role in people's life. Although automobiles have different qualities and various forms, various faults will inevitably occur during their use, which need to be eliminated or repaired in time. With the development of society and the progress of science and technology, more and more electronic technology, automation technology and computer technology are used in the design and production of automobiles. On the one hand, the degree of automation of automobiles is getting higher and higher, and the performance is better Superior, more convenient and flexible operation, on the other hand, it also puts forward higher requirements for vehicle maintenance and test...

AI Technical Summary

Problems solved by technology

There are also various types of equipment for vehicle detection and diagnosis, and the prices are not cheap

However, most of the current equipment functions are relatively single, and the operation methods are different. Sometimes maintenance technicians need to use several equipment at the same time for comprehensive diagnosis to find the problem.

In this way, it not only brings high equipment cost and training cost to the repair shop, but also it is difficult to achieve synchronization and coordination of multiple devices when used for a long time
