The invention discloses a car audio playing management method and system, and relates to the technical field of car audio playing management, and the method comprises the steps: building a mapping relation between different sound sources and audio usage scenes, and obtaining a first mapping relation table; setting an audio channel, establishing a mapping relation between different sound sources and the audio channel, and obtaining a second mapping relation table; matching the first mapping relation table with the second mapping relation table to obtain a corresponding relation between the audio use scene and the audio channel; before audio data are played, an audio usage scene applies for an audio focus from a preset management strategy, when the audio focus is configured for the audio usage scene, a corresponding audio channel is opened, and the audio data are transmitted to a digital signal processor to be played; and when the audio focus is rejected to be configured for the audio use scene, the corresponding audio channel is not opened, and the audio data is discarded. According to the invention, the purpose of compulsory application following the focus mechanism can be achieved, and the abnormal sound mixing condition of the vehicle machine system is avoided.

    本发明公开了一种车机音频播放管理方法和系统,涉及车机音频播放管理的技术领域,包括建立不同音源与音频使用场景的映射关系,获得第一映射关系表;设置音频通道,建立不同音源与音频通道的映射关系,获得第二映射关系表;匹配第一映射关系表和第二映射关系表,获得音频使用场景与音频通道的对应关系;播放音频数据前,音频使用场景向预设的管理策略申请音频焦点,当为所述音频使用场景配置音频焦点时,对应的音频通道开启,音频数据传输至数字信号处理器进行播放;当拒绝为音频使用场景配置音频焦点时,对应的音频通道不开启,音频数据丢弃。本发明能够达成强制应用遵循焦点机制的目的,避免了车机系统出现异常混音的情况。
