Objective position information supplying method in navigation system, and navigation system
First Claim
1. An objective position information supplying method in a navigation system of detecting a present position of a self vehicle, comprising the steps of:
- judging whether or not a distance between the detected present position and an objective position is within a predetermined distance set for each of objections positions, which include a position scheduled to pass therethrough and a position scheduled to arrived thereat;
judging whether or not a direction to the detected present position from the objective position is within a first angle range, which is selected in advance for each of the objective positions, said first angle range being relative to a direction of the self vehicle entering each of the objective positions, said selected first angle range being stored in a memory device as first angle range data for each of the objective positions;
judging whether or not a direction to the objective position from the detected present position is within a second angle range, which is set with respect to an advance direction of the self vehicle at the detected present position; and
supplying a predetermined kind of information as for the objective position to a driver if the judged distance is within the predetermined distance, if the judged direction to the detected present position is within the first angle range, and if the judged direction to the objective position is within the second angle range.

Abstract
An objective position information supplying method in a navigation system for detecting a present position of a self vehicle, includes the steps of: judging whether or not a distance between the detected present position and an objective position is within a predetermined distance set for each of objective positions, which include a position scheduled to pass therethrough and a position scheduled to arrive thereat; judging whether or not a direction to the detected present position from the objective position is within a first angle range, which is set for each of the objective positions on a standard of a direction of the self vehicle to enter each of the objective positions; judging whether or not a direction to the objective position from the detected present position is within a second angle range, which is set with respect to an advance direction of the self vehicle at the detected present position; and supplying a predetermined kind of information as for the objective position to a driver if the judged distance is within the predetermined distance, if the judged direction to the detected present position is within the first angle range, and if the judged direction to the objective position is within the second angle range.

9. A navigation system comprising:
-
a detection means for detecting a present position of a self vehicle; a judgment means for judging whether or not a distance between the detected present position and an objective position is within a predetermined distance set for each of objective positions, which include a position scheduled to pass therethrough and a position scheduled to arrive thereat, judging whether or not a direction to the detected present position from the objective position is within a first angle range, which is selected in advance for each of the objective positions, said first angle range being relative to a direction of the self vehicle entering each of the objective positions, and judging whether or not a direction to the objective position from the detected present position is within a second angle range, which is set with respect to an advance direction of the self vehicle at the detected present position; a memory means for storing the selected first angle range as first angle range data for each of the objective positions; and an information supply means for supplying a predetermined kind of information as for the objective position to a driver if the judged distance is within the predetermined distance, if the judged direction to the detected present position is within the first angle range, and if the judged direction to the objective position is within the second angle range according to a judgment result of said judgment means. - View Dependent Claims (10, 11, 12, 13, 14)
