NAVIGATION SYSTEM WITH FUNCTION OF ONE-TOUCH MAP MATCHING CORRECTION AND METHOD THEREOF
First Claim
1. A navigation system with a function of map matching correction, for matching self position and driving direction to map data and displaying the map-matched position and direction, the system comprising:
- a GPS module for receiving each position signal from a plurality of GPS satellites, measuring the self position and driving direction, and outputting information on the measured position and direction;
a map database for storing the map data;
a storage unit for storing a candidate designation index, road information corresponding to the candidate designation index, a guidance stop flag, a flag activating a map-matching correction button, and voice data for road sequence guidance;
a display unit for, under a predetermined control, displaying the map data, activating or deactivating the map-matching correction button, magnifying and displaying candidate roads, and generating a coordinate value of a position on a screen pressed by an external force; and
a controller for, when there are one or more parallel roads within a predetermined distance from a road of the map-matched position, indexing the parallel roads, generating a candidate road array for storing information on roads including a road of the map-matched position according to an indexing sequence, activating the map-matching correction button, and sequentially selecting candidate roads of the candidate road array depending on the number of times of pressing the map-matching correction button while performing the map matching correction.

9. A method of correcting map matching in a navigation system having a function of map matching correction, the method comprising the steps of:
-
measuring a current position and, when there are one or more parallel roads within a predetermined distance from a road of the measured position, preparing an array for storing indexes for and information on the road of the measured position and the parallel roads and corresponding to the stored indexes, and activating a map-matching correction button; and
sequentially moving the roads according to an indexing sequence by the number of times of pressing the map-matching correction button, while performing the map matching correction.
