The present invention for achieving the object as described above, in the auxiliary device equipped with a portable terminal configured to enable voice and text communication with the other party and wireless information retrieval from the Internet website, the terminal mounting unit 100 ) And a display unit 200 capable of wireless communication with the terminal mounting unit 100, wherein the terminal mounting unit 100 is a portable terminal equipped with a web browser for wireless Internet search ( Various information transmitted and received between the mounting unit 11 on which the 10) is mounted and the portable terminal 10 mounted on the mounting unit 11 and the RF module 18 via the RS-232C communication port 12. And wirelessly transmit the various information processed by the main CPU 13 and the main CPU 13 to control the operation of a digital signal processor (DSP) for speech recognition to the display unit 200, and an antenna 19 It is composed of an RF module 18 for providing a radio signal received from the display unit 200 to the main CPU 13, the display unit 200 is transmitted from the portable terminal mounting unit 100 RF module 25 for receiving the received radio signal through the antenna 24 to the sub CPU 26, and wirelessly transmits the various data processed in the sub CPU 26 to the portable terminal mounting unit 100. And the sub-CPU 26 and the sub-CPU 26 controlling the driving of the monitor 27 and processing various types of information transmitted and received between the RF module 25 and the monitor 27. The monitor 27 is configured to display a search window and a search information window for wireless Internet search by the operation of the web browser of the terminal 10.

In this case, an LCD or a TFT is used as the monitor 27 for the wireless Internet search and the extended display 27 for displaying the searched web information, which may be installed in a vehicle or various other spaces.

In the drawings, reference numeral 9 denotes a key pad, 15 an audio amp, 16 a speaker, 17 a mic, 20 and 21 a regulator, and 22 a The power controller 23 is main power.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with an exemplary drawing.

Referring to FIGS. 1A, 2B, and 2, after the portable terminal mounting unit 100 is mounted at a predetermined position of a vehicle, a pair of display units 200 are installed at a predetermined position of the vehicle. The driver, i.e., the user, may perform voice or text communication with the other party or search for information on the Internet website regardless of driving. In other words, you can talk with the other party or search the Internet while looking at the extended monitor 27.

First, when the Internet is connected by a key of the portable terminal 10 mounted on the mounting unit 11 or a keypad 9 connected to the mounting unit 11, the monitor 27 in the portable terminal 10 is connected to the monitor 27. The search box for searching the Internet is displayed by the operation of the web browser.

Of course, the various information output from the portable terminal 10 is provided to the main CPU 13 through the RS-232C communication port 12 and processed, which is converted into a radio signal in the RF module 18 and then the antenna ( 19) to be transmitted to the air wirelessly.

Then, the RF module 25 of the display unit 200 converts the information about the search box received through the antenna 24 and provides it to the sub CPU 26. Accordingly, the monitor 27 extended by the control of the sub CPU 26 displays a search window for searching the Internet.

When the user views the search box displayed on the extended monitor 27 and selects web information provided by a plurality of Internet websites by operating the keypad 9, the corresponding web information is installed at a predetermined position of the vehicle. It will be displayed on the extended monitor 27. Of course, the above web information is also transmitted to the display unit 200 by wireless, as in the case of the search window is naturally displayed. Therefore, the display unit 200 including the monitor 27 composed of LCD, TFT, or the like can be installed anywhere in the vehicle, that is, where the driver's gaze is most comfortable.

Preferably, by configuring a plurality of keys around the monitor 27 or by integrally configuring the touch screen, the search box or search information displayed on the extended monitor 27 may be directly selected on the monitor 27.

Of course, when making a voice call as in a conventional portable terminal, the voice signal of the other party received through the portable terminal 10 is processed by the DSP 14 for speech recognition and then amplified by the audio amplifier 15. The voice signal output to the speaker 16 and, conversely, collected by the microphone 17 is processed by the DSP 14 for voice recognition and then transmitted to the counterpart through the portable terminal 10. Therefore, the driver can make a telephone call with the other party while driving while holding the portable terminal to his ear.

According to the present invention, a wireless display can be installed regardless of a place or a space by wirelessly connecting an expanded display to an auxiliary device of a communication terminal such as a mobile phone or a PDA. You can check the window or searched web information on the extended display, which makes searching the Internet more convenient.

In particular, when the present invention is applied to a hands-free vehicle mounted on a vehicle, a driver may view a desired location by viewing a search box for internet search such as a map or web information by internet search in a more enlarged screen among the driver. The effect is to go smoothly.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention. will be.
