The present invention relates to an in-vehicle audio device, and more particularly, to an in-vehicle audio device and a control method thereof in which a driver in a vehicle shares data with a nearby vehicle through Bluetooth communication.

In general, a vehicle audio system plays radio reception, plays back audio recorded on a tape, plays back CD-DA and MP3 audio recorded on a Compact Disk (CD) / Digital Video Disk (DVD). In general, the audio system outputs through a plurality of speakers installed in a vehicle to reproduce the audio, allowing the passengers to listen to the rich audio.

In addition, a variety of portable MP3 players are recently being distributed, and these MP3 players (MP3 Players) are being integrated into mobile phones, personal digital assistants (PDAs), PDA phones, and the like.

In addition, such integrated devices use the term "Bluetooth device" as a generic term for devices such as MP3P, PDA, PDA phone, etc., which can form a short-range wireless network with external devices. .) Equipped.

In accordance with this trend, a Bluetooth module is also provided in a vehicle audio system to output MP3 audio reproduced in the Bluetooth device through a vehicle audio system providing rich sound.

However, in the prior art, when the user's voice or sound signal is transmitted to a driver of a nearby vehicle, the voice or voice signal is transmitted through the path of the calling Bluetooth module-> the calling wireless terminal-> the receiving wireless terminal-> the receiving Bluetooth module. Since a sound source signal is transmitted, there is a problem in that it cannot be transmitted when the receiving wireless terminal is in an off state or on a call.

An object of the present invention is to solve the conventional problems as described above, a vehicle audio device and a control method for sharing data with a nearby vehicle by direct Bluetooth communication between Bluetooth modules provided in the vehicle audio device without intervening a wireless terminal The purpose is to provide.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

1 is a block diagram schematically illustrating a configuration of an in-vehicle audio device to which an embodiment of the present invention is applied.

As shown in FIG. 1, an in-vehicle audio device 100 for applying the present invention includes a Bluetooth module 110, a display unit 130, and an audio controller 150.

The Bluetooth module 110 may search for a vehicle audio device (hereinafter, referred to as an adjacent vehicle audio device) having a Bluetooth module adjacent thereto.

That is, a search signal is broadcast by setting a frequency hopping sequence to search for communication-enabled Bluetooth devices located in the vicinity. Bluetooth devices that scan the inquiry signal are synchronized with the frequency of the inquiry signal and then send the Bluetooth device address and clock information to the Bluetooth device that broadcasts the inquiry signal and search for a Bluetooth device that can communicate. Bluetooth devices are likely to be searched for Bluetooth devices that can communicate.

The display unit 130 displays a search list of the communicable adjacent vehicle audio device.

The audio controller 150 controls the Bluetooth module 110 to perform a search operation when the search request is made through the input unit 120 from a user, and displays a list of audio device for the adjacent vehicle according to the search result. Control to transmit the selected data to the designated adjacent vehicle audio device.

In addition, the audio controller 150 transmits a message requesting permission to transmit data before transmitting the selected data to a designated adjacent vehicle audio device, and then transmits the data only when there is a permission response thereto. Control to send to the audio device.

In addition, the audio controller 150 controls the display to be displayed on the display unit when the permission of data transmission is requested from the audio device for the adjacent vehicle after the Bluetooth module 110 is turned on. In the case of receiving data from the audio device of the adjacent vehicle, in the form of data, that is, voice data, the audio is reproduced through the path of the audio processing unit 140-> amplifier unit 170-> speaker 200 and the sound source. In the case of data, the data is controlled to be stored through a path of the audio processor 140-> audio controller 150-> storage 160.

When described in detail with reference to the accompanying drawings the operation of the embodiment according to the present invention configured as described above.

In the present invention, a control method of an in-vehicle audio device includes a process of transmitting selected data to an in-vehicle audio device (hereinafter referred to as an in-vehicle audio device) having a Bluetooth module adjacent to the periphery, and receiving data from an in-vehicle audio device. The data reception process will be described after the data transmission process.

2 is a flowchart illustrating a process of controlling transmission of voice or sound source data according to an embodiment of the present invention.

Referring to FIG. 2, when the Bluetooth module 110 is turned on, the Bluetooth module 110 automatically switches to the Bluetooth communication mode (S200), and when a search request of an adjacent vehicle audio device is input from the user through the input unit 120 (S210), the audio controller. 150 performs a search for an adjacent vehicle audio device through the Bluetooth module 110 (S220).

When a plurality of adjacent vehicle audio devices that can communicate according to the search of step S220 are found, the audio control unit 150 displays the list on the display unit 130 (S230 and S240).

Based on the list displayed on the display unit 130 in step S240, the user designates an adjacent vehicle audio device to be transmitted through the input unit 120, and then selects one of voice or sound source data (S250). It is also possible for a user to designate transmission of voice or sound source data to the plurality of adjacent vehicle audio devices individually.

That is, for example, it is possible to designate transmission of voice or sound source data to a plurality of searched adjacent car audio devices in common, or to designate transmission of voice data to some of the plurality of car audio devices and transmit sound source data to others. have.

Accordingly, the audio control unit 150 requests transmission of the selected data to the adjacent vehicle audio device designated in step S250 through the Bluetooth module 110 (S260).

If transmission is allowed in response to the request of step S260 (S270), the corresponding data is transmitted to the audio device for the adjacent vehicle that allows the transmission (S280). In this case, when transmission is not allowed, the display unit 130 displays a message for the adjacent vehicle audio device that has refused transmission.

3 is a flowchart illustrating a reception control process of voice or sound source data according to an exemplary embodiment of the present invention.

Referring to FIG. 3, when the Bluetooth module 110 is turned on, the Bluetooth module 110 automatically switches to the Bluetooth communication mode (S300), and when the permission of data transmission is requested from the audio device for the adjacent vehicle (S310), the audio controller 150 is performed. Through the display unit 130 informs the user that there is a request for permission to transmit data from the audio device for the adjacent vehicle. In response to this, the user determines whether to allow transmission (S320).

When the user determines to allow the transmission through the input unit 120 in step S320, the audio controller 150 reproduces the data received from the adjacent in-vehicle audio device and stores or reproduces the data to the speaker 200.

That is, after determining the data type (S330), in the case of voice data, the audio processing unit 140-> amplifier unit 170-> reproduced by the path of the speaker 200 (S340), in the case of sound source data The audio processor 140 stores audio through the path of the audio controller 150 through the storage 160 (S350).

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example and can be variously changed in the range which does not deviate from the summary.
