基于i.MX6车载音视频系统的设计和实现

摘要

With the development of auto industry and electronic technology, the auto tend to be more electronic, and the vehicle audio and video system playing critical role in auto mobile human-computer interaction attract researcher's new focus. This paper puts forward the application scheme of combination of the mobile phone and vehicle audio and video system, and analyzes the hardware modules and software flow chart of the vehicle audio and video system based on i.MX6 and driver initialization using the method of state machine. After the system function test had been done, the results show that the audio and video system realizes the multi screen interactive and solve the real time charging problem for mobile devices.%随着汽车产业和电子技术的发展,车载系统的电子化程度越来越高,车载音视频系统作为汽车人机交互的重要组成部分,正成为研究的新热点.本文提出了智能手机和车载音视频系统相结合的应用方案,分析了实现i.MX6车载音视频系统的硬件模块和软件流程图,驱动初始化状态机实现方法. 系统测试结果表明本文提出的音视频系统实现了音视频基本功能,还可实现多屏互动,并提供移动设备实时充电解决方案.
