Abstract

The invention relates to a vehicle-mounted instrument fault detection system and a fault detection method thereof. The jig includes a single-chip microcomputer and a second CAN chip. The invention utilizes a single-chip microcomputer to send a detection signal to the warning light of the target instrument, and the detection fixture receives the response signal corresponding to the warning light of the target instrument through the second CAN chip, and the single-chip microcomputer judges the detection result of the warning light of the target instrument according to the receiving situation of the response signal for fast and accurate detection Check whether the instrument warning light is malfunctioning. Solve the problem of low efficiency and error-prone problems that traditional on-board instrument fault detection methods need to manually detect multiple instrument warning lights when detecting hard-wired control instrument warning lights. The automatic detection of the warning lights of each instrument on the vehicle instrument is realized, and the detection efficiency and reliability of the vehicle instrument fault detection system are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a vehicle instrument fault detection system and a detection method thereof. Background technique [0002] With the development of automobile technology and the continuous progress of microprocessor technology, the embedded system has been widely used in automobile electronic technology. [0003] For vehicle-mounted embedded systems, such as instruments and multimedia systems, when the production line or testing department adopts the traditional method to detect the fault of the hard-wired warning light, it is necessary to manually find the corresponding light line, connect the effective level, and then observe the instrument display. Whether the warning light corresponding to the screen is lit. Because there are too many warning lights, it is easy to miss, especially in mass production, the efficiency is low, human eyes are tired, and it is easy to make mistakes. Conte...
