Embodiment Construction

[0011] The present invention is described in further detail below by specific embodiment:

[0012] In actual use, on the compatible machine, an engine failure language broadcast system is added, and all information inside the microcomputer is stored, processed, transmitted, and converted to each other in the form of binary codes. The microcomputer and the filtering and judging processor are connected with each other. The electric speaker is restricted by the filtering and judging processor. When the engine electronic control system fails, the filtering and judging processor sends an audio signal to the electric loudspeaker, and the electric loudspeaker broadcasts the fault language. A constant prepared in advance is broadcast 3 times, and a signal is used to substitute the value to make the system work in a faulty state, also known as "sick work".

[0013] In the ECU electronic control device system, the input circuit amplifies, filters, shapes and transforms various signals i...

Abstract

The invention relates to the comprehensive development and employment of driving, safety, energy saving and maintenance engineering of automobiles. Based on a programming principle of a computer, an operation function of an audio engine fault alarm system is additionally arranged on a compatible machine, interlinked sequential machine languages are arranged in a CPU (Central Processing Unit), and a digitalized sound signal is reported by using a loudspeaker through reduced (decompressed) digital-to-analogue conversion.

Description

technical field [0001] The invention relates to the comprehensive development and utilization of automobile driving, safety and energy saving, and maintenance engineering, and belongs to the automobile maintenance engineering. Background technique [0002] When the existing automobile fails, most of them are self-diagnosed failure CHECK indicator light display, or the driver informs the maintenance personnel of the maintenance manufacturer of the automobile failure phenomenon, and the maintenance personnel realizes man-machine dialogue with a decoder to judge and maintain. But for the driver, he doesn't know what the fault is, what harm and consequences it has, whether it is possible to continue driving to the destination for repairs, and reduce unnecessary losses. Contents of the invention [0003] The purpose of the present invention is to reduce unnecessary losses, and to design a corresponding programming language based on the specific conditions of the automobile desi...
