Claims
- 1. A navigation terminal comprising:
a positioning unit for positioning a current location of a mobile unit; a setting unit for setting up a place of departure and a place of destination; a communication unit for transmitting and receiving information to and from an information center; a temporary storage unit for storing the drive route information received by the communication unit; and a drive guide unit for guiding the driving on the basis of the current location positioned by the positioning unit and the drive route information stored in the temporary storage unit, wherein when the drive route information received by the communication unit is the information of a partial drive route in the total drive route connecting the place of destination and the place of departure that are set up by the setting unit, the guide unit starts the drive guide on the basis of the received information of the partial drive route.
- 2. The navigation terminal according to claim 1, wherein
the navigation terminal receives the remaining drive route information from an end of the partial drive route to the place of destination while the guide unit is making the drive guide on the basis of the information of the partial drive route.
- 3. A navigation system comprising:
a navigation terminal including a positioning unit for positioning a current location of a mobile unit, a setting unit for setting up a place of departure and a place of destination, a communication unit for transmitting and receiving information to and from an information center, a temporary storage unit for storing the drive route information received by the communication unit, and a drive guide unit for guiding the driving on the basis of the current location positioned by the positioning unit and the drive route information stored in the temporary storage unit; an information center having a center communication unit for receiving the information indicating the place of departure and the place of destination transmitted by the communication unit; and a drive route calculation part for calculating the drive route on the basis of the information indicating the place of departure and the place of destination received by the center communication unit, wherein when the drive route information received by the communication unit is the information of a partial drive route in the total drive route connecting the place of destination and the place of departure that are set up by the setting unit, the guide unit starts the drive guide on the basis of the received information of the partial drive route.
- 4. A computer program making a computer function as a navigation terminal comprising:
a positioning unit for positioning a current location of a mobile unit; a setting unit for setting up a place of departure and a place of destination; a communication unit for transmitting and receiving information to and from an information center; a temporary storage unit for storing the drive route information received by the communication unit; and a drive guide unit for guiding the driving on the basis of the current location positioned by the positioning unit and the drive route information stored in the temporary storage unit, wherein when the drive route information received by the communication unit is the information of a partial drive route in the total drive route connecting the place of destination and the place of departure that are set up by the setting unit, the guide unit starts the drive guide on the basis of the received information of the partial drive route.
- 5. A computer program making a computer function as a navigation system comprising:
a navigation terminal including a positioning unit for positioning a current location of a mobile unit, a setting unit for setting up a place of departure and a place of destination, a communication unit for transmitting and receiving information to and from an information center, a temporary storage unit for storing the drive route information received by the communication unit, and a drive guide unit for guiding the driving on the basis of the current location positioned by the positioning unit and the drive route information stored in the temporary storage unit; an information center having a center communication unit for receiving the information indicating the place of departure and the place of destination transmitted by the communication unit; and a drive route calculation part for calculating the drive route on the basis of the information indicating the place of departure and the place of destination received by the center communication unit, wherein when the drive route information received by the communication unit is the information of a partial drive route in the total drive route connecting the place of destination and the place of departure that are set up by the setting unit, the guide unit starts the drive guide on the basis of the received information of the partial drive route.
- 6. A drive guide method for use at a navigation terminal, the navigation terminal including a positioning unit for positioning a current location of a mobile unit, a setting unit for setting up a place of departure and a place of destination, a communication unit for transmitting and receiving information to and from an information center, a temporary storage unit for storing the drive route information received by the communication unit; and a drive guide unit for guiding the driving on the basis of the current location positioned by the positioning unit and the drive route information stored in the temporary storage unit, the method comprising:
receiving information from the information center by the communication unit; and starting the drive guide by the guide unit on the basis of the received information, when the drive route information received by the communication unit is the information of a partial drive route in the total drive route connecting the place of destination and the place of departure that are set up by the setting unit.
