Automobile diagnosis system and method thereof

Abstract

The invention discloses an automobile diagnosis system and a method thereof. The system comprises an upper computer and a lower computer. The upper computer and the lower computer are connected through wired or wireless communication. The upper computer is provided with a user application program. The lower computer is provided with an automobile diagnosis program. The lower computer interacts with an automobile to detected according to a diagnosis instruction acquired by the user application program of the upper computer so as to acquire a diagnosis signal. The automobile diagnosis program calls a corresponding algorithm stored in the lower computer and automobile text data to carry out operation on the diagnosis signal so as to acquire a diagnosis result and feeds back the diagnosis result to the upper computer. In the automobile diagnosis system and the method, an automobile diagnosis operation process is performed in the lower computer, the upper computer is used for acquiring the diagnosis instruction and displaying the diagnosis result, the upper computer adopts electronic equipment possessing input, display and communication functions and there are various forms; and based on a system platform of the lower computer, a set of diagnosis program is developed, research and development cost is low and the program is not easy to crack.

Description

technical field [0001] The invention relates to the technical field of automobile diagnosis, in particular to an automobile diagnosis system and method. Background technique [0002] The vehicle diagnosis system is composed of two parts, the upper computer and the lower computer. The upper computer is mainly responsible for interacting with users, and there are many forms, such as Windows computers, Windows tablets, Android phones, Android tablets, Apple phones, Apple tablets, and so on. The lower computer mainly interacts with the car, usually a single-chip microcomputer, and one of its functions is to process communication signals that interact with the car, such as CAN signals. [0003] Traditional automotive diagnostic systems come in various forms, but their design ideas are basically based on the upper computer, such as image 3 As shown, the upper computer 20 of the traditional automotive diagnostic system includes a user application program 201, an automotive diagno...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the diagnostic program of the automobile diagnostic system is very large, and the upper computer 20 has various forms, the diagnostic program needs to be written and maintained on different platforms, which increases the workload of a lot of research and development and testing

[0005] (2) In addition to the diagnostic program, the database of the automotive diagnostic system is also very large, some even exceed 10G, which makes it impossible to install and run on some platforms with weak performance (such as mobile phones), or it will seriously affect the performance and occupy a lot of space.

[0006] (3) The automobile diagnostic program and database are based on the host computer 20, such as Windows operating system and Android operating system, because these platform cracking techniques are popular, they are easy to be cracked

[0007] Due to some of the above problems in the traditional automotive diagnostic system, the traditional automotive diagnostic system can only be applied to some specific upper computers, and its use is limited.
