As shown, the control unit 100 includes a GPS input unit 131 for receiving position information of the vehicle transmitted from the GPS receiver 500; A memory storage unit 132 for storing voice data, a map, and various kinds of information; A power supply unit 133 for supplying operation power to each unit; A voice output unit 134 for outputting voice information such as announcements through the audio 700 and the speaker 300; Battery charging unit 135 for charging the battery of the mobile phone (800); A voice signal processor 136 for processing a voice signal of the mobile phone 800 to perform a hands-free function; A gyro sensor 137 for detecting a rotation angle of the vehicle; By referring to the position information of the vehicle received from the GPS receiver 500, the information received from the mobile phone 800 and the map information stored therein, the moving path of the vehicle is determined and displayed on the liquid crystal display 120. On the other hand, when the GPS signal is not received from the GPS receiver 500 to determine the position of the vehicle by calculating the rotation angle and the moving speed respectively input from the gyro sensor 137 and the speed sensor 900 installed in the vehicle It is composed of a central processing unit (139).

Here, the speed sensor 900 is a sensor installed in a drive unit such as a wheel tire of a vehicle to detect a moving speed of the vehicle, and the detected data is input to the central processing unit 139 of the control unit 100.

5 is a view showing a state of use of the vehicle telematics system of the present invention, Figure 6 is a view showing the front portion of the control unit of the present invention.

As shown in the drawing, the control unit 100 receives various types of living information along with road guidance and telephone communication through wireless communication with an Internet information center and displays them on the liquid crystal display 120. 120 is configured by dividing the main display window 121 and the auxiliary display window 122 to selectively display the map and various information. In addition, the remote control switch operation unit 200 further includes an emergency button 210 for calling an emergency rescue service using wireless communication.

Referring to the operation of the present invention configured in this way in more detail as follows.

First, when the user requests directions to a desired destination by voice and text through the microphone 600 or the remote control switch operation unit 200, the control unit 100 uses the mobile phone 800 as a modem in real time from the Internet information center. By downloading the road guidance information considering the traffic information wirelessly and displays the turn-by-turn display with the map owned on the screen of the liquid crystal display unit 120 of the control unit 100, the speaker 700 linked with the audio 700 (300) ) Provides a guidance service to the user by the announcement broadcast.

In this case, the door speaker 300 outputs a relative voice from the RH speaker through audio during a phone call, and outputs a path guide voice through audio from the LH speaker when performing the route guidance function.

Here, the control unit 100 has optimized the usability by owning the map itself and downloading the road guide route considering the real-time traffic information from the information center, and at least optimizing the amount of data received from the information center by owning the map. System.

Referring to the operation of the control unit 100 in more detail, as shown in Figure 4, the power supply unit 133 supplies the operating power to each part of the control unit 100, voice to the memory storage unit 132 Data, maps and various information are stored in advance. In this state, when the user requests a road guidance through the remote control switch operation unit 200, the panel switch operation unit 110, or the microphone 600, the GPS input unit 131 receives the location information of the vehicle transmitted from the GPS receiver 500. Receive input.

In addition, when the driving of the vehicle starts, the gyro sensor 137 detects the rotation angle of the vehicle, and the speed sensor 900 installed in the vehicle body detects the moving speed of the vehicle.

Therefore, the central processing unit 139 determines the moving path of the vehicle by referring to the location information of the vehicle received from the GPS receiver 500, the information received from the mobile phone 800, and the map information stored therein. When the GPS signal is not received from the GPS receiver 500 while being displayed on the liquid crystal display 120, the rotation angle and the moving speed respectively input from the gyro sensor 137 and the speed sensor 900 installed in the vehicle. Determine the location of the vehicle by calculating the, the voice output unit 134 outputs the voice information, such as the announcement and the road guidance through the audio 700 and the speaker 300.

On the other hand, when the user wants to make a mobile phone call, the voice signal processor 136 processes the voice signal of the mobile phone 800 to perform a hands-free function, and the battery charger 135 charges the battery of the mobile phone 800. Make sure your phone works properly.

In addition, in the existing system, only the turn-by-turn display is displayed on the small screen of the mobile phone 800, so that the user's recognition of the guidance path at the intersection becomes a problem, but in the present invention, the map is provided on the liquid crystal display 120 separately provided. By displaying, the user's perception of the guidance path can be greatly improved.

In addition, the conventional system is to interfere with the user's safe driving by operating the key of the mobile phone 800 to use the function while driving, the present invention is to position the remote control switch control unit 200 in the driving handle, that is, the steering wheel It does not affect the safe driving because it does not take your hands off the steering wheel for driving directions and hands-free phone calls while driving.

In addition, the button configuration of the remote control switch operation unit 200 and the panel switch operation unit 110 is briefly composed of a back button to return to the previous menu, a voice button to enable voice input, a confirmation / call button and a four-way button, The operability is optimized so that all functions can be operated with the minimum operation switch.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

As described above, according to the vehicle telematics system according to the present invention, the telematics control unit has its own map and improves the recognition and usability by displaying the movement route on the map together with the turn-by-turn indication, and all the functions. Maximize convenience and safety by operating the remote control switch, optimize the operability so that all functions can be operated with the minimum operation switch, and accurately determine the moving position by using the vehicle's internal sensor even when GPS signal is not received. It works.
