Embodiment Construction

[0024] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.

[0025] The invention provides a car fault diagnosis system based on the Android platform. The invention reads the fault codes in the ECU of the car through a mobile terminal, and uses the car fault expert analysis module to deduce the cause of the fault. The present invention solves the current problem based on PC The diagnostic instrument is inconvenient to carry when going out, and the hardware cost of the handheld diagnostic instrument based on the single-chip microcomputer / FPGA is high, and the system maintenance and upgrade are troublesome, and the work efficiency of the automobile maintenance personnel is improved.

[0026] Such as figure 1 Shown is the system block diagram of the present invention:

[0027] Mobile terminal 1, an Android phone or tablet that supports Bluetooth function, used to run a car fault diagnosis applicatio...

Abstract

The invention provides an automobile fault diagnosis system based on an Android platform. The automobile fault diagnosis system comprises an ECU and a CAN bus, and further comprises a data conversion module, an automobile fault decoding module and an automobile fault expert analysis module, wherein one end of the data conversion module is connected with the CAN bus, the other end of the data conversion module is connected with a Bluetooth module in a wireless mode, the Bluetooth module is connected with the automobile fault decoding module, and the automobile fault decoding module is connected with the automobile fault expert analysis module. The automobile fault diagnosis system lowers automobile fault diagnosis cost, enables a diagnosis process to be more convenient, and improves automobile maintenance efficiency.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an Android platform-based automotive fault diagnosis system. Background technique [0002] The existing automobile fault diagnosis system can read out, display, store and process the fault codes in the automobile ECU, and can easily and accurately detect automobile faults, which is beneficial to the detection of automobile operating conditions and automobile fault maintenance. At present, there are mainly two kinds of automobile fault diagnosis instrument schemes designed at home and abroad: the fault diagnosis instrument based on PC and the handheld fault diagnosis instrument based on single-chip microcomputer / FPGA (Field Programmable Gate Array, that is, Field Programmable Gate Array). The hardware cost of these two solutions is relatively high, and the diagnostic instrument based on the PC is not convenient to carry. In addition, even if the maintenance personnel have dia...
