Vehicle diagnosis system and method based on mobile phone platform

Abstract

The invention relates to vehicle diagnosis system and method based on a mobile phone platform. The system comprises a vehicle electric control unit, a diagnosis communication box, and an intelligent mobile phone provided with an embedded operating system, wherein the diagnosis communication box is inserted in the vehicle electric control unit and carries out wireless or wire data communication with the intelligent mobile phone; and the intelligent mobile phone is internally provided with a diagnosis application program, carries out information interaction with the diagnosis communication box through operating the diagnosis application program, and further checks vehicle diagnosis information and sends corresponding function operating commands. In the vehicle diagnosis system and method based on the mobile phone platform, the traditional mobile phone equipment is fully utilized on the basis of the mobile phone platform, the cost is considered, and the function of the vehicle diagnosis system and the friendless of interfaces are enriched; a vehicle owner can check the health condition of the self vehicle by using the self mobile phone to operate the diagnosis software of the vehicle as long as being near the vehicle, and can give a certain reference and help for some simple maintenances, and better meets the requirements on respective vehicle diagnosis.

Description

technical field [0001] The invention relates to a vehicle diagnosis system and method, in particular to a mobile phone platform-based vehicle diagnosis system and method. 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 testing. The tradi...

Problems solved by technology

Since the decoder dedicated to automobile faults belongs to the professional maintenance equipment of automobile repair stations and 4S shops, the cost is high and the equipment is large in size, which is not convenient for ordinary car owners and car enthusiasts to use and carry. The product design and structure itself cannot display more detailed vehicle diagnostic information, and cannot meet the needs of car owners and car enthusiasts to instantly understand the vehicle's operating conditions

[0004] At present, various personal diagnostic products have appeared on the market, but these devices are all independent, and must have their own display, processing and other components, and these products are generally small products. It is realized by single-chip microcomputer, which is relatively lacking in function and friendly interface.
