In order for Bluetooth pairing to be performed between the user terminal and the AVN terminal, both terminals must have a NFC (Near Field Communication) chip, and it is inconvenient to approach the terminal closely. However, since the AVN terminal 100 and the user terminal 300 according to the disclosed embodiment do not require a separate chip to be installed, access between the terminals is not required when the Bluetooth is paired.

Hereinafter, a flow of an operation for performing Bluetooth pairing between the AVN terminal 100 and the user terminal 300 will be described.

9 is a flowchart illustrating an operation between an AVN terminal and a user terminal for Bluetooth pairing according to an exemplary embodiment of the present invention.

Referring to FIG. 9, the AVN terminal 100 may receive a control command related to Bluetooth pairing from a user (900). For example, as shown in FIG. 4, the user touches the 'Bluetooth connection' icon 401 displayed on the display 101 through the touch screen or clicks through the controller to input a control command related to Bluetooth pairing can do.

In response to receiving the control command related to Bluetooth pairing, the AVN terminal 100 may transmit a Bluetooth pairing command to the user terminal 300 (910). At this time, the AVN terminal 100 can transmit the Bluetooth pairing command converted through voice to the voice through the speaker. That is, the AVN terminal 100 can convert a control command represented by an electrical signal into a control command expressed by a voice using a voice conversion module, and then transmit the control command through a speaker.

The AVN terminal 100 may identify the user terminal 300 operating the Bluetooth antenna within a predetermined range and receive authentication information and identification information from one of the identified user terminals 300. [ The predetermined range may be a range in which the AVN terminal 100 can be connected to the user terminal through the Bluetooth communication network, but is not limited thereto. For example, the predetermined range may indicate a range that supports the Bluetooth communication network through the communication module built in the AVN terminal 100. [

At this time, when connected to the user terminal 300 connected through the USB port 103, the AVN terminal 100 can identify the user terminal 300 through the USB port 103, If not connected, the AVN terminal 100 can identify the user terminal 300 in which the Bluetooth mode is activated, i.e., the Bluetooth terminal is operating within a predetermined range.

As described above, the user terminal 300 can receive a voice command through the voice recognition sensor, and can recognize the voice command received through the voice recognition engine, thereby helping to perform the corresponding process .

For example, the user terminal 300 can receive the Bluetooth pairing command through the built-in voice recognition sensor and recognize that the voice recognition engine corresponds to a command to activate the Bluetooth mode. Accordingly, the user terminal 300 may operate the Bluetooth antenna to activate the Bluetooth mode (920). In addition, the AVN terminal 100 may operate the Bluetooth antenna to activate the Bluetooth mode (930).

In Bluetooth pairing, the Bluetooth mode of the user terminal 300 and the AVN terminal 100 must be activated and the authentication procedure of the user terminal 300 and the AVN terminal 100 must be completed. In order to perform the authentication procedure, the user terminal 300 may transmit the identification information of the user terminal 300 as well as the authentication information of the user (940).

When the authentication information is stored in the memory, the AVN terminal 300 can search whether the authentication information matched with the authentication information received from the user terminal 300 among the authentication information previously stored in the memory exists.

  As another example, if the data to which the identification information is mapped in the authentication information is stored in the memory, the AVN terminal 300 searches the authentication information mapped with the identification information of the user terminal 300 among the authentication information previously stored in the memory , It is possible to compare whether the retrieved authentication information matches the authentication information received from the user terminal 300. [ As a result of the search, if authentication information previously stored in the memory matches the authentication information received from the user terminal 300, the authentication procedure is normally completed and Bluetooth pairing can be performed.

If it is determined that the authentication information matches (950), the authentication procedure between the AVN terminal 100 and the user terminal 300 is completed. At this time, if the Bluetooth pairing host is the AVN terminal 100, the AVN terminal 100 may transmit the identification information of the AVN terminal 100 to the user terminal 300 (960). Accordingly, the user terminal 300 can recognize that the process for Bluetooth pairing is completed, and can recognize that the connected host is the AVN terminal 100 through the Bluetooth pairing.

The user terminal 300 can transmit to the user that the Bluetooth pairing is completed based on the identification information received from the AVN terminal 100. [ For example, the user terminal 300 may notify the user that the Bluetooth pairing is completed through the speaker, or may inform the user that the Bluetooth pairing is completed through the display.

According to one embodiment, the user terminal 300 may transmit a pop-up message to the user informing that the Bluetooth pairing is completed based on the identification information received from the AVN terminal 100. [ As shown in FIG. 6, the user terminal 300 may display a pop-up message indicating that the connection with the HYUNDAI NAVIGATION is completed through the display 350.

In addition, the AVN terminal 100 may also notify the user that the Bluetooth pairing is completed through at least one of the display 101 and the speaker 143. For example, referring to FIG. 7, the AVN terminal 100 may display a pop-up message 700 indicating that the user terminal 300 is connected to the top of the screen through the display 101. 8, the AVN terminal 100 may display a pop-up message 800 informing that the user terminal 300 is connected to the center of the screen through the display 101. [ That is, depending on the manner in which the interface is configured, the pop-up messages 700 and 800 may be displayed in various forms as well as displayed in various locations, but are not limited thereto.

Meanwhile, 'SHV-E250S' corresponding to the product number of the user terminal 300 is included in the pop-up message shown in FIGS. 7 and 8 as identification information of the user terminal 300. However, the AVN terminal 100 may also include various information for identifying the user terminal 300, such as a serial number and a MAC address of the user terminal 300, in a pop-up message, It is not.

Meanwhile, the user terminal 300 and the AVN terminal 100 can complete the Bluetooth pairing (970, 980), and both terminals can send various data through the Bluetooth communication network.

Conventionally, the user terminal and the AVN terminal must be built in the NFC chip, and the NFC and the Bluetooth mode must be activated. In addition, there is a disadvantage in that a separate application for Bluetooth pairing must be installed and executed, and the terminals to be paired with Bluetooth should be brought close to each other so that simple security paring (SSP) is performed, and Bluetooth pairing is performed.

The AVN terminal 100 and the user terminal 300 according to the disclosed embodiment need not include an NFC chip in a terminal to be Bluetooth-paired and do not need to install a separate application. Therefore, the user can more conveniently use the Bluetooth communication network.

10 is a diagram illustrating a case where a plurality of user terminals are identified in a vehicle according to an exemplary embodiment and a Bluetooth pairing command is transmitted to a plurality of identified user terminals.

There is not necessarily only one user terminal in the vehicle, but a plurality of user terminals may exist. As shown in FIG. 10, a plurality of user terminals 300, 301, 302, and 303 may exist in the in-vehicle seats 21, 22, 23,

Upon receipt of a control command related to Bluetooth pairing from the user, the AVN terminal 100 can transmit a Bluetooth pairing command containing information to activate the Bluetooth mode through the speaker. Correspondingly, the plurality of user terminals 300, 301, 302, and 303 existing in the vehicle can receive the Bluetooth pairing command output from the speaker and activate the Bluetooth mode.

Accordingly, the AVN terminal 100 can identify a plurality of user terminals 300, 301, 302, and 303 in which the Bluetooth mode is activated within a predetermined range. The predetermined range described below means a range in which the Bluetooth Pairing command is received and the Bluetooth terminal is able to identify the activated user terminal. The predetermined range may be set within a range in which Bluetooth pairing is possible, or may be set by a user or a designer, and there is no limitation. For example, the AVN terminal 100 may identify the user terminals 300, 301, 302, and 303 located in the vehicle among the user terminals operating the Bluetooth antenna through the communication module.

At least one user terminal among the identified user terminals 300, 301, 302, and 303 may transmit authentication information and identification information to the AVN terminal 100. According to one embodiment, as shown in FIG. 10, the AVN terminal 100 may receive at least one of authentication information and identification information from the user terminal 300 located in the passenger seat 22.

Accordingly, the AVN terminal 100 can search whether or not the authentication information matched with the authentication information received from the user terminal 300 is stored in the memory. Alternatively, the AVN terminal 100 can check the identification information received from the user terminal 300 and search whether or not the authentication information to which the above-described identification information is mapped is stored in the memory. If authentication information matching the authentication information received from the user terminal 300 is stored in the memory, the authentication is completed and the AVN terminal 100 and the user terminal 300 can be connected through the Bluetooth communication network.

In addition, the AVN terminal 100 can receive authentication information from two or more user terminals. For example, the AVN terminal 100 may receive authentication information and identification information from the user terminal 300 located in the driver's seat 21 in addition to the user terminal 300 located in the passenger seat 22.

For example, when the user terminal 300 located in the front passenger seat 22 and the user terminal 300 located in the driver's seat 21 are normally authenticated, the AVN terminal 100 can access the user terminal 300 located in the passenger seat 22, The user terminal 301 located in the driver's seat 21 can be connected to the two user terminals 300 and 301 via the Bluetooth communication network by performing multi-pairing.

As another example, the AVN terminal 100 may display a screen on which at least one of the two user terminals 300 and 301 can be selected through the display. Accordingly, the AVN terminal 100 may perform multi-pairing with respect to two user terminals 300 and 301 according to a user's selection, or may perform Bluetooth pairing with only one user terminal.

11 is a flowchart showing an operation of a vehicle supporting Bluetooth pairing with a user terminal.

The vehicle may receive a control command related to Bluetooth pairing through devices capable of receiving various control commands from the user (1100). For example, as shown in FIG. 2, the vehicle includes a center input unit 43 implemented by a display 101 navigation input unit 102 implemented as a touch screen type, a jog shuttle type controller, or a hard key type controller, The user can receive a control command related to Bluetooth pairing from the user.

When receiving a control command related to Bluetooth pairing, the vehicle can transmit a Bluetooth pairing command converted to voice using the voice conversion module to the user terminal (1110). For example, the vehicle can output a Bluetooth pairing command converted to voice through a speaker and transmit it to the user terminal.

Accordingly, the vehicle may identify one or more user terminals that are within a predetermined range (1120). The predetermined range is a range in which the user terminal in which the Bluetooth mode is activated can be identified.

The vehicle may identify user terminals operating the Bluetooth antenna within a predetermined range and receive authentication information and identification information from one of the identified user terminals. The predetermined range is a range in which the vehicle can recognize that the Bluetooth antenna is operating, and may be a range in which the vehicle can be connected to the user terminal through the Bluetooth communication network, but is not limited thereto.

Meanwhile, the vehicle can receive the authentication information and the identification information through the communication module, and can search whether the received authentication information is stored in the memory. That is, after the vehicle receives at least one of the user authentication information and the user terminal identification information from the user terminal in advance, only the authentication information is stored in advance in the memory, or the identification information is mapped to the authentication information and stored in advance in the memory , And can be used for an authentication procedure when Bluetooth pairing is performed later.

If it is determined that the authentication information related to the search result identification information is stored, the vehicle determines whether Bluetooth pairing with the user terminal is to be performed based on whether the corresponding authentication information stored in the memory is matched with the authentication information received through the communication module (1130).

If it is determined that the authentication information is matched, the authentication is completed, and the vehicle can perform Bluetooth pairing with the user terminal through the communication module (1140). Accordingly, the vehicle can exchange various data with the user terminal through the Bluetooth communication network. For example, the vehicle may receive a music file from a user terminal and play the music file received via the speaker. In addition, the vehicle may receive the moving image file from the user terminal and reproduce the moving image file received through the display, but the present invention is not limited thereto.

12 is a flowchart illustrating an operation of a user terminal supporting Bluetooth pairing with an AVN terminal.

The user terminal may receive the Bluetooth pairing command through the speech recognition engine 1200 and may perform a process corresponding to the received Bluetooth pairing command. For example, the user terminal may turn on the operation of the Bluetooth antenna to activate the Bluetooth mode (1210).

In addition, the user terminal may transmit the authentication information of the user and the identification information of the user terminal to the AVN terminal in order to perform the authentication procedure required for Bluetooth pairing. At this time, the user terminal can transmit the authentication information of the user and the identification information of the user terminal to the vehicle through the communication module.

The AVN terminal determines whether or not the authentication information of the user received from the user terminal matches the authentication information of the user stored in the in-vehicle memory. If it is determined that the authentication information matches, the AVN terminal can complete the authentication procedure.

Accordingly, the AVN terminal can transmit the identification information, thereby enabling the user terminal to recognize that the authentication procedure is completed. That is, the user terminal can receive the identification information from the AVN terminal (1230). At this time, the user terminal transmits the identification information through the pop-up message, and at the same time, it can transmit to the user that the authentication process is completed and the Bluetooth pairing is performed, and the identification information and the Bluetooth pairing are performed to the user through various methods . Accordingly, the user terminal performs Bluetooth pairing (1240), and can exchange various information with the AVN terminal through the Bluetooth communication network.
