The invention provides an automobile audio fault processing system and a processing method thereof, and belongs to the technical field of automobile audio fault processing, during working, a processing module sends a first digital audio signal to an audio decoding module, a first analog audio signal is obtained after decoding, and the first analog audio signal is output to the processing module and a power amplifier module. The processing module detects the first analog audio signal and judges whether the audio decoding module decodes successfully. If not, fault information is transmitted to the main controller; and if successful, the power amplifier module amplifies the signal and drives the audio output module to produce sound. The audio receiving module collects sound to obtain a second analog audio signal, and the second analog audio signal is converted into a second digital audio signal to be input into the processing module. The processing module compares the two digital audio signals, and if the two digital audio signals are consistent, no fault exists; if not, each module is detected through the vehicle-mounted diagnosis system, and fault information is output to the vehicle-mounted display screen through the main controller. Fault detection is comprehensive, and part of faults can be automatically solved.

    本发明提供一种汽车音频故障处理系统及其处理方法,属于汽车音频故障处理技术领域,工作时,处理模块向音频解码模块发送第一数字音频信号,解码后得到第一模拟音频信号,该信号被输出至处理模块和功放模块。处理模块检测第一模拟音频信号,判断音频解码模块是否解码成功。若失败,将故障信息传至主控制器;若成功,功放模块放大信号,驱动音频输出模块发声。音频接收模块采集声音得到第二模拟音频信号,经预处理模块转换为第二数字音频信号输入处理模块。处理模块比对两个数字音频信号,一致则无故障;不一致则通过车载诊断系统检测各模块,将故障信息经主控制器输出至车载显示屏。本发明故障检测全面,并可自动解决部分故障。
