It can be delivered to the users (passengers) (S320).

Then, the control unit 106 determines whether it is time to transmit the location data of the vehicle to the exchange server 200 (S330). As a result of the determination, when the transmission time is reached, the controller 106 transmits the identification information, the position data, and the time data of the vehicle to the exchange server 200 through the wireless communication controller 103, and the exchange server 200 All information received from the vehicle terminal 100 is transmitted to the control server 300 (S340).

In addition, the control unit 106 determines whether the content is received from the exchange server 200 through the wireless communication control unit 103 (S350). As a result of the determination in step S350, when the content is received from the exchange server 200, the controller 106 classifies the content by type and stores the content in the first storage unit 101, and then the content is stored in a predetermined order. 1 is displayed through the display unit 105 (S360).

On the other hand, the control server 300 is matched with the coordinates of the map and the location data received from the vehicle terminal 100 via the exchange server 200 and the network communication network 400 through the S340 process and displayed on the screen, By displaying the display of the vehicle displayed on the screen differently using the identification information of each vehicle, the operator of the control server 300 can easily and accurately determine the current driving state by linking the vehicles as well as the current position of the vehicles Support. For example, when the control server 300 receives the location data of bus 1, the control server 300 may search for a stop between the bus 1 and the bus moving in front of the bus 1, and the estimated time of arrival of the bus to each of the detected stops. It is possible to detect a building near the bus movement, and the like is transmitted to the terminal 100 of the vehicle and the portable terminal 600 of the vehicle user so that the user can easily recognize the driving situation of the vehicle.

In addition, the control server 300 processes a variety of information, such as news and traffic information and provides the content to the vehicle terminal 100 every predetermined time, the control server 300 is a unique number of each registered vehicle, that is, Using the phone number, the content is transmitted to the vehicle terminal 100 through the exchange server 200.

In addition, the control server 300 predicts the arrival time of the vehicle stop by using the position data and time data of the vehicle transmitted from the vehicle terminal 100, and the predicted information exchange server 200 and the network communication network 400 Through) transmits to a terminal 600 that the user can carry and carry, such as a portable telephone or a PDA. In this case, since the arrival time of the vehicle station expressed through the user terminal 600 is continuously displayed until the next scheduled time is transmitted, the vehicle users can use the vehicle accurately at a desired time.
