1. A control device for changing screen and audio of an AVN (Audio, Video, Navigation) system based on a mode of a vehicle, the control device comprising:
a surrounding-state-information acquisition unit including a camera and a microphone, and configure to acquire surrounding state information of a vehicle; an output unit configured to output the surrounding state information acquired by the surrounding-state-information acquisition unit; a gear-shifting-state sensing unit configured to sense a shifting state of a gear of the vehicle; a booting execution unit configured to perform an initial booting process for booting the AVN system when a system power is applied with a start of an engine of the vehicle; a control unit configured
to output the surrounding state information acquired by the surrounding-state-information acquisition unit from the output unit with priority over the initial booting screen and audio outputted by the booting execution unit when a reverse gear state is sensed by the gear-shifting-state sensing unit while the initial booting process is being performed by the booting execution unit, andto output a video signal from the surrounding-state-information acquisition unit, reduce a first audio volume corresponding to a first audio signal, and increase a second audio volume corresponding to a second audio signal outputted in a mode corresponding to the reverse gear state to a level higher than the first audio volume, when the reverse gear state is sensed by the gear-shifting-state sensing unit while outputting the first audio signal; and an input unit configured to receive an input to select the mode of the vehicle from
a media mode for playing a video or an audio,a toggle mode for switching the mode between two different modes with pressing a first button, in which a video or an audio different from the video or the audio of the media mode is playable, anda sustain mode for irreversibly switching the mode with pressing a second button, in which a video or an audio different from the videos or the audios of the media mode and the toggle mode is playable, wherein,
when the first button is pressed while the video or the audio of the media mode is being played, the control unit is configured
to store the media mode as a hold mode,to mute the video or the audio being of the media mode being played, andto play the video or the audio of the toggle mode,when the first button is pressed again while the video or the audio of the toggle mode is being played, the control unit is configured to play the video or the audio of the media mode stored as the hold mode, andwhen the second button is pressed while the video or the audio of the media mode or the toggle mode, the control unit is configured to play the video or the audio of the sustain mode. |
