Diagnosis Method of Vehicle State Based on Combination of Graphics and Text

Abstract

The invention provides an image and text combined vehicle state diagnosis method, which comprises the following steps that 1, a client is provided; 2, a server is provided; 3, a vehicle is provided, and the vehicle comprises a plurality of electric control systems; 4, the client is initialized, and a diagnosis function is started; 5, the client identifies the vehicle; 6, the client or the server obtains the corresponding circuit information and diagnosis information, and in addition, the standard parameters of the current required data items are obtained according to the diagnosis function; 7, the client obtains the real-time parameters of each electric control system of the vehicle; 8, the client or the server utilizes the database technology for processing the diagnosis real-time parameter of each electric control system of the vehicle, and in addition, the processing results are displayed by adopting a vector diagram dynamic generation technology; and 9, if users do not have operation, the step 7 and the step 8 are cyclically repeated, and if the users carry out function selection operation, the operation is executed according to the user operation.

Description

technical field [0001] The invention relates to the field of automobile diagnosis, in particular to an automobile state diagnosis method. Background technique [0002] With the development of science and the progress of society, automobiles have become the most familiar and common means of transportation for people, and they play a very important role in people's lives. 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 advancement 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 more superior. , the operation is more convenient and flexible. On the other hand, it also puts forward higher requireme...

Problems solved by technology

With the development of society and the advancement 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 more superior. , the operation is more convenient and flexible. On the other hand, it also puts forward higher requirements for vehicle maintenance and testing. The traditional manual monitoring and maintenance methods can no longer meet the maintenance needs of new vehicles.

[0003] With the rapid development of automobile automatic control technology, more and more computer-controlled systems are used, the structure of automobiles is becoming more and more complex, and the fault diagnosis of automobiles is becoming more and more complicated.

At present, automobile diagnostic equipment and automobile maintenance data (circuit diagrams, threshold ranges, etc.) are either in a separate state, or there are not only static text and picture prompts, but the current vehicle electronic control system (including automobile computers, execution units, sensors, etc.) ) has a complex structure. When an abnormality occurs in the circuit, it is difficult for maintenance personnel to locate the abnormality, which is not conducive to the analysis and positioning of the abnormality. At present, the maintenance of the electronic control system is simply replacing the vehicle components instead of the damaged electronic components, and the maintenance cost is relatively expensive.
