在实际应用中，不同的车内情景模式所关注的车控状态特征可能不同，比如，接打电话情景更关注车控音量特征，而车内外人员交流场景更关注车控车窗特征，因此，车控状态特征可以根据不同的车内情景模式选择车控音量特征和车控车窗特征中的任意一种或两种。
为便于理解本申请公开的音量调节方法，本申请提供了几种车内情景模式，并针对每种车内情景模式提供了对应的音频播放音量调控策略，也即，步骤S103具体包括：
(1)车内乘员休息情景
在当前车内情景模式为车内乘员休息情景时，将乘员休息区域的音频播放音量降低至第一音频播放值。
本实施例中的第一音频播放值的取值依据实际需要而定，优选取值为0。
车辆行驶过程中，当车载音频设备播放音频时，比如，播放音乐和导航，根据车内摄像头采集车内环境图像识别副驾乘员状态和后排乘员状态，当有车内乘员休息时，将乘员休息区域的音频播放音量降低至第一音频播放值。
本实施例中的乘员休息区域包括：副驾驶区域和后排区域。当只有后排乘员休息时，此时，可以仅将后排区域的音频播放音量降低至第一音频播放值；当副驾乘员和后排乘员均休息时，除驾驶员侧音响播放音频外，其他位置的音频播放音量均降低至第一音频播放值。在实际应用中，还可 以播放白噪音进行助眠。
当车辆配置有头枕音响时，可以通过主驾侧头枕音响播放音频，对于其他位置的音频播放音量均降低至第一音频播放值。
本实施例中的车内摄像头包括：OMS(Occupant Monitoring Sensor，乘员监控传感器)摄像头和DMS(Driver Monitoring System，驾驶员监控系统)摄像头。
在当前车内情景模式为预设音量增大情景时，将所述乘员休息区域的音频播放音量从所述第一音频播放值以渐强方式增大至正常状态对应的音量；
其中，所述预测音量增大模式为：车内乘员睡醒或车辆当前位置距离目的地的剩余距离为预设距离。
具体的，当根据车内摄像头采集车内环境图像识别出车内乘员睡醒时，可以在乘员睡醒预设时间段后，比如1分钟，从第一音频播放值以渐强方式增大至正常状态对应的音量。
本实施例中的正常状态指的是，车内乘员均未休息时的状态。
当根据导航路线确定车辆当前位置距离距离目的地的剩余距离为预设距离时，从第一音频播放值以渐强方式增大至正常状态对应的音量，以使乘客提前苏醒，准备在车辆到达目的地时下车。
其中，预设距离的取值依据实际需要而定，本申请在此不做限定。
(2)车内乘员接打电话情景
在当前车内情景模式为车内乘员接打电话情景时，将车内音频播放音量降低至第二音频播放值；
当检测到车内乘员停止接打电话时，将车内音频播放音量由所述第二音频播放值以渐强方式增大至正常状态对应的音量。
其中，第二音频播放值的取值与第一音频播放值的取值可以相同或是不同，具体取值依据实际需要而定，本申请在此不做限定。
在实际应用中，当车内信号检测器检测到车内有电话信号接入时，将车内音频播放音量降低，还可以控制车内氛围灯闪烁提醒车内乘员有电话 信号接入。
根据车内摄像头采集的车内环境图像确定车内乘员是否接打电话，当车内乘员接打电话时，持续降低车内音频播放音量至第二音频播放值。当检测到车内有电话信号接入，而车内乘员未接听电话时，可以在预设时间段后，将降低的车内音频播放音量恢复至正常状态对应的音量。
在车内乘员接打电话过程中，实时采集车内环境图像，当根据车内摄像头采集的车内环境图像确定车内乘员停止接打电话时，可以控制音频播放音量进入播放。
(3)车内乘员交流情景
在当前车内情景模式为车内乘员交流情景时，开启音量闪避功能；
当车内乘员交流结束时，关闭所述音量闪避功能，并将车内音频播放音量恢复至正常状态对应的音量；
其中，所述车内乘员交流场景为：检测到人声以及乘员之间的动作交互。
本实施例中的音量闪避功能指的是：在人说话和不说话的时候，声卡能够自动调节背景音乐的音量大小。音量闪避功能具有渐入渐出的效果。
具体的，当车载音频设备播放音频时，若音频播放音量较大，则车内乘员沟通交流时需要大声说话，甚至喊着说话。
本申请在车载音频设备播放音频时，根据车内麦克风实时检测人声，以及根据车内摄像头实时检测车内乘员之间的交互动作，当根据人声和车内乘员之间的交互动作确定当前处于车内乘员交流场景时，开启音量闪避功能。当在车内乘员交流结束，比如预设时间段内未检测到人声时，关闭音量闪避功能，并将车内音频播放音量恢复至正常状态对应的音量。
(4)车内外人员交流情景
在当前车内情景模式为车内外人员交流情景时，将车内音频播放音量降低至第三音频播放值；
当车内外人员交流结束时，将车内音频播放音量由所述第三音频播放值恢复至正常状态对应的音量；
其中，所述车内外人员交流场景为：车内播放音频且音频播放音量大于预设音频音量，车速降低至0，车辆侧窗打开，车内乘员的视线或者头部所指方向朝向打开的车辆侧窗；或者，车速降低至0，车门打开，车内乘员的视线或者头部所指方向朝向打开的车门或下车。
本实施例中，当车内播放音频音量较高超过预设音量时，车内播放音频必然会对车内外人员交流产生影响，因此，本申请在确定当前车内情景模式为车内外人员交流情景时，将车内音频播放音量降低至第三音频播放值，以保证车内外人员交流顺畅。
其中，第三音频播放值的取值依据实际需要而定，本申请在此不做限定。
