Abstract

In the case where a line for connecting the communication section mounted on the navigation terminal with the center communication section provided in the information center is established and the starting point information and the destination information are sent from the navigation terminal to the information center, the current position of a vehicle, which is measured after the completion of the connection of the line, is sent to the information center as the starting point information. According to the thus sent information, a drive route is calculated in the information center.

Claims

1. A navigation terminal comprising:

a measurement section for measuring a current position of a movable body;

a communication section for transmitting information to an information center; and

a destination setting section for setting a destination, wherein;

after the communication section establishes a connection line with the information center, the communication section transmits information indicating the measured current position as information for router search.

2. The navigation terminal according to claim 1, wherein the information for the router search include information indicating the destination.

3. A navigation system comprising:

a navigation terminal; and

an information center, wherein;

the navigation terminal includes;

a measurement section for measuring a current position of a movable body;

a communication section for transmitting information to the information center; and

a destination setting section for setting a destination;

after the communication section establishes a connection line with the information center, the communication section transmits information indicating the measured current position as information for router search; and

the information center receives the information for the route search.

4. A computer program making a computer function as a navigation terminal comprising:

a measurement section for measuring a current position of a movable body;

a communication section for transmitting information to an information center; and

a destination setting section for setting a destination, wherein;

after the communication section establishes a connection line with the information center, the communication section transmits information indicating the measured current position as information for router search.

5. A computer program making a computer function as a navigation system comprising:

a navigation terminal; and

an information center, wherein;

the navigation terminal includes;

a measurement section for measuring a current position of a movable body;

a communication section for transmitting information to the information center; and

a destination setting section for setting a destination;

after the communication section establishes a connection line with the information center, the communication section transmits information indicating the measured current position as information for router search; and

the information center receives the information for the route search.

6. An information transmission method for a navigation apparatus, the method comprising:

measuring a current position of a movable body;

transmitting information to an information center; and

setting a destination, wherein;

the transmitted information is information indicating the current position, which is measured after a connection line between the navigation terminal and the information center is established.
