中央控制端2为车载计算机中央计算平台，包括用于座舱的控制及运算的芯片。中央控制端2与至少一个头戴式显示设备3连接，中 央控制端2用于接收包括视频信号和音频信号的混合信号，并将该混合信号传输至至少一个头戴式显示设备3。
头戴式显示设备3可以为AR/VR/MR等增强现实设备，多个用户佩戴头戴式显示设备3并坐在座舱内的各个座位上。头戴式显示设备3既可以是一体式头戴式显示设备，也可以是分体式头戴式显示设备。示例地，头戴式显示设备3与中央控制端2可通过有线方式连接，例如，头戴式显示设备3与中央控制端2可通过车规级信号传输线连接。
本申请通过包括多媒体设备1、中央控制端2以及至少一个头戴式显示设备3、多媒体设备1与中央控制端2连接且多媒体设备1用于将包括视频信号和音频信号的混合信号传输至中央控制端2、中央控制端2与头戴式显示设备3连接且中央控制端2用于接收该混合信号，并将该混合信号传输至头戴式显示设备3，实现了在车辆内运行多媒体设备，并且允许座舱内的多个用户同时通过所佩戴的头戴式显示设备观摩多媒体设备中的游戏进展，满足了用户社交需求，提高了用户体验。
在根据本申请所述的车载增强现实系统的第一实施例中，多媒体设备1与中央控制端2通过HDMI或DP接口连接，中央控制端2包括分解模块21、中央控制模块22以及至少一个输出模块23，其中，分解模块21的输入端与多媒体设备1通过HDMI或DP接口连接，分解模块21的输出端与中央控制模块22连接，中央控制模块22与至少一个输出模块23连接，输出模块23与头戴式显示设备3连接。
分解模块21用于接收多媒体设备1所传输的包括视频信号和音频信号的混合信号，并将该混合信号分解成视频信号以及音频信号，并将视频信号以及音频信号传输至中央控制模块22。具体地，分解模块21优选为HDMI/DP转CSI和I2S的芯片，能够将包括视频信号和音频信号的混合信号分解成单独的视频信号以及音频信号，并将视频信号通过CSI接口输入中央控制模块22，将音频信号通过I2S接口输入中央控制模块22。中央控制模块22用于接收该视频信号以及音频信号，并将该视频信号以及音频信号混合成混合信号后传输至至少一个输出模块23。具体地，中央控制模块22将从CSI接口输入的视 频信号和从I2S接口输入的音频信号经过内部处理后完成混合从而产生包括视频信号和音频信号的混合信号，并将该混合信号通过内部总线传输到至少一个输出模块23。
