1. A navigation system for a vehicle comprising:
- a receiver that receives transportation information and fuel efficiency information from one or more source vehicles located in a specific region;
a remote central processing unit (CPU) that generates navigation information of the specific region using the transportation information and the fuel efficiency information;
a transmitter that receives navigation information from the CPU, and transmits the received navigation information to a target vehicle; and
a database that accumulates the transportation information and the fuel efficiency information of the specific region and stores the accumulated information,wherein the CPU provides the target vehicle with navigation information that is generated using real-time transportation information and real-time fuel efficiency information during a predetermined range from a start time to a predetermined time and provides the target vehicle with navigation information generated using transportation information and fuel efficiency information that is pre-stored in the database after the predetermined time.

11. A navigation method for a vehicle by a navigation system comprising:
-
a) receiving a route search request for a specific region from a target vehicle by a receiver of the navigation system; b) receiving transportation information and fuel efficiency information from source vehicles located in the specific region by the receiver; c) generating navigation information using the transportation information and the fuel efficiency information by a remote central processing unit (CPU) of the navigation system; d) transmitting the received navigation information to the target vehicle by a transmitter of the navigation system; and e) accumulating the transportation information and the fuel efficiency information of the specific region and storing the accumulated information in a database, wherein the CPU provides the target vehicle with navigation information that is generated using real-time transportation information and real-time fuel efficiency information during a predetermined range from a start time to a predetermined time and provides the target vehicle with navigation information generated using transportation information and fuel efficiency information that is pre-stored in the database after the predetermined time. - View Dependent Claims (12, 13, 14)
