摘　　要：随着智能汽车娱乐功能的快速发展,车机系统的屏幕数量也越来越多,功能也越来越丰富。但是由于原有设计中副屏的声音输出的设计局限,副屏的声音链路比较复杂,不利于软硬件的后期功能的开发和维护。因此,文章充分利用智能座舱的声音处理与蓝牙设备管理模块,把副驾声音控制和蓝牙耳机的控制逻辑整合到智能座舱内,统一了娱乐系统中多音区的管理,缩短了副屏音频数据的数据传输链路,解决了副屏音频数据传输延迟大的问题,提高了用户体验。With the rapid development of intelligent car entertainment functions,the number of screens in the car machine system is also increasing,and the functions are becoming more and more rich.However,due to the design limitations of the sound output of the secondary screen in the original design,the sound link of the secondary screen is more complicated,which is not conducive to the development and maintenance of the later functions of the software and hardware.Therefore,this paper makes full use of the sound processing and Bluetooth device management module of the intelligent cockpit,integrates the co-pilot voice control and the control logic of the Bluetooth headset into the intelligent cockpit,unifies the management of multiple audio areas in the entertainment system,shortens the data transmission link of the audio data of the secondary screen,solves the problem of large delay in audio data transmission of the secondary screen,and improves the user experience.
