A method for realizing multi-channel parallel vehicle diagnosis and vehicle diagnosis equipment

Abstract

The invention relates to an automobile diagnostic method for achieving multi-channel parallel. The automobile diagnostic method includes the steps that S1, a plurality of channel connection protocol instructions are issued to automobile communication interface equipment by a diagnostic terminal of automobile diagnostic equipment; S2, whether communication protocol class objects corresponding to the channel connection protocol instructions are established or not is checked by the automobile communication interface equipment; if not, the S3 is executed; if yes, the S4 is executed; S3, the communication protocol class objects are respectively established according to the channel connection protocol instructions, channel IDs of automobile computer systems, corresponding to the communication protocol class objects are recorded, and the S4 is executed; S4, the diagnostic terminal distributes diagnostic scanning instructions to all the automobile computer systems according to the channel IDs of the automobile computer systems, so that interaction of the automobile diagnostic equipment and the automobile computer systems corresponding to the channel IDs is achieved. By means of the automobile diagnostic method for achieving multi-channel parallel and the automobile diagnostic equipment, multi-channel parallel communications can be achieved, the equipment can be in communication connection with the automobile computer systems, data information of the automobile computer systems is read in a parallel mode so that the related diagnostic function can be achieved, maintenance time is shortened, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis, in particular to a method for realizing multi-channel parallel automobile diagnosis and automobile diagnosis equipment. Background technique [0002] With the rapid development of modern automobile technology and the frequent emergence of hybrid and electric vehicles, the structure of automobile electronic control systems is becoming more and more complex. High and new technologies, especially electronic technology and computer technology, have been more and more widely used in automobiles. The concentrated application of these high and new technologies in automobiles will not only improve the safety and comfort of automobiles to the greatest extent, but also prevent future automobile failures. The detection and maintenance of the system have brought great challenges. In today's increasingly fierce competition, the pressure of industry competition is increasing, and the same problem...

AI Technical Summary

Problems solved by technology

Existing automotive diagnostic technology has the following disadvantages: 1. Slow speed, single-channel scanning one by one, it takes several hours in vehicles with dozens or even hundreds of computing systems; 2. High maintenance costs; 3. It takes a long time, which will certainly increase the maintenance cost of the vehicle; 4. Response speed, single-channel scanning, the user's sense of use is slow response; 5. Low stability, in the diagnosis of the car computer system that requires dual systems to be connected at the same time , due to the non-stop switching of channels, it is easy to cause disconnection of the connection, and it is necessary to re-enter
