The invention discloses a vehicle audio control method and device and a computer program product, and the method comprises the steps: adding a state interface of which the state is sent out and can be called externally when a vehicle machine system receives information of entering a low-power-consumption state, and endowing the state interface with a state identifier for indicating that the vehicle machine system enters the low-power-consumption state; and in response to the state identifier, stopping transmission of all audio data, and closing an audio output channel. By optimizing the audio resource management strategy of the in-vehicle entertainment system, the audio resources occupied by all applications are quickly and uniformly released in the dormancy preparation stage, the time for the in-vehicle entertainment system to enter the dormancy state is remarkably shortened, and the situation that the overall dormancy process is blocked due to audio processing delay of individual applications is effectively avoided. And meanwhile, the energy consumption of the vehicle in a low-power-consumption mode is reduced, and the energy efficiency ratio of the vehicle-mounted terminal system is increased. In addition, when the user uses the car next time, the system can quickly start and recover the audio function, and the user experience is improved.
本发明公开一种车辆音频控制方法、装置及计算机程序产品,其中,方法包括:在车机系统接收到进入低功耗状态的信息时,增加一个状态外发且外部可调用的状态接口,并为其赋予用于表示车机系统进入低功耗状态的状态标识;响应于所述状态标识,停止所有音频数据的传输,并关闭音频输出通道。本发明通过优化车机系统的音频资源管理策略,实现了在休眠准备阶段快速、统一地释放所有应用占用的音频资源,显著缩短了车机系统进入休眠状态的时间,有效避免了因个别应用音频处理延迟而导致的整体休眠进程受阻。同时,本发明降低了车辆在低功耗模式下的能耗,提升了车机系统的能效比。此外,用户下次用车时,系统能够迅速启动并恢复音频功能,提高了用户体验。
