Control device for changing screen and audio of AVN system based on mode of vehicle
A control device for changing screen and audio of an AVN system includes a surrounding-state-information acquisition unit that acquires surrounding state information of a vehicle, an output unit that outputs the surrounding state information acquired by the surrounding-state-information acquisition unit, a gear-shifting-state sensing unit that senses a shifting state of a gear of the vehicle, a booting execution unit that performs an initial booting process for booting the AVN system when a system power is applied with a start of an engine of the vehicle, and a control unit that outputs 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.
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, and
to 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, and
a 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, and
to 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, and
when 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.
2. The control device according to claim 1 , wherein
the media mode includes at least iPod mode, DTV mode, DVD mode, Music mode, Photo mode, Radio mode, Video mode, Bluetooth™ Music mode, Digital TV mode, Aux Audio mode, and Aux video mode,
the toggle mode includes at least INFO mode, HOME mode, and CLIMATE mode, and
the sustain mode includes at least MAP (DEST, ROUTE) mode, Phone mode, and Setup mode.
3. The control device according to claim 1 , wherein icons for the media mode, the toggle mode, and the sustain mode are arranged and displayed on a foreground of the screen in order of a frequency of use.
