Abstract

Disclosed are a telematics terminal and a method for transmitting route guidance information data fitted to a receiving terminal. The method includes the steps of initializing operational conditions of a mobile communication terminal by transmitting device information of the telematics terminal to the mobile communication terminal when a connection between the telematics terminal and the mobile communication terminal is detected, receiving display performance information from the mobile communication terminal, creating route guidance data to be transferred to the mobile communication terminal for telematics services, selecting a route guidance region to be transferred to the mobile communication terminal from route guidance data based on the display performance information of the mobile communication terminal and reconstructing route guidance data for the selected route guidance region, and transmitting the reconstructed route guidance data to the mobile communication terminal. Thus, it is possible for the users to use telematics services without exchanging the mobile communication terminals.

Claims

1. A method for transmitting route guidance data from a telematics terminal including images and vector data to a receiving terminal, the method comprising the steps of:

(i) initializing operational conditions of a mobile communication terminal by transmitting device information of the telematics terminal to the mobile communication terminal when a connection between the telematics terminal and the mobile communication terminal is detected;

(ii) receiving display performance information from the mobile communication terminal;

(iii) creating route guidance data for telematics services to be transferred to the mobile communication terminal;

(iv) selecting a route guidance region to be transferred to the mobile communication terminal from route guidance data created in step (iii) based on the display performance information of the mobile communication terminal received in step (ii) and reconstructing route guidance data for the selected route guidance region; and

(v) transmitting the route guidance data reconstructed in step (iv) to the mobile communication terminal.

2. The method as claimed in claim 1, further comprising the steps of:

monitoring position movement information of a vehicle in the route guidance data displayed in the mobile communication terminal; and

repeating steps (iv) and (v) when a position of the vehicle deviates from a route guidance data area displayed in the mobile communication terminal.

3. The method as claimed in claim 1, wherein data communication is carried out between the telematics terminal and the mobile communication terminal through a universal serial bus interface.

4. The method as claimed in claim 1, wherein in step (i), the mobile communication terminal receiving the device information of the telematics terminal initializes an application corresponding to the device information and transmits a response message thereof to the telematics terminal.
