Vehicle navigation server, and vehicle navigation device and system using the same
First Claim
1. A vehicle navigation server comprising:
- a travel route calculating device for calculating at least one proposed travel route of a vehicle based on data input by a registrant to the server, the data including a current or start position and a destination of the vehicle;
a traffic information extracting device for extracting traffic information relating to the proposed travel route from a traffic information storage device;
a communication point setting device for defining at least one communication point on the proposed travel route, so as to newly extract traffic information for an area from each communication point to the destination from the traffic information storage device and to send the newly extracted traffic information to a vehicle navigation device built in the vehicle when the vehicle passed the communication point;
a data storage device for storing at least data for identifying the registrant, data of said at least one proposed travel route, and data of said at least one communication point, and a data sending device for sending at least the traffic information and the data of said at least one communication point to the vehicle navigation device, wherein said at least one communication point includes a point from which a detour route for taking a longer way around a place noted in the traffic information can be defined; and
the traffic information sent to the vehicle navigation device is a combination of detailed information about a section from the current or start position of the vehicle to selected one of said at least one communication point and simplified information about a section from the selected communication point to the destination.

Abstract
A vehicle navigation system for selecting a suitable travel route based on transmitted traffic information. A server calculates a proposed travel route based on input data and defines communication points so as to newly extract traffic information for an area from each communication point to the destination from a traffic information storage device, where a point from which a detour around a place noted in the traffic information is included. The server stores data for identifying the registrant, the proposed travel route, and the communication points in a storage device and sends the traffic information and communication points to a vehicle navigation device. The sent traffic information includes detailed information about a section from the current or start position of the vehicle to the closest communication point to the vehicle on the way to the destination and simplified information about a section from this point to the destination.
