Embodiment Construction

[0035]Various embodiments of the invention will now be described in detail, examples of which are illustrated in the accompanying drawings. The same reference numbers are used throughout the drawings to refer to the same or like parts.

[0036] refer to figure 2 , figure 2 A block diagram of a navigation system that includes a GPS receiver 210 that receives navigation messages transmitted from a plurality of GPS satellites (not shown in the figure). The GPS receiver 210 calculates and outputs a DOP (dilution of precision) value representing a degree of reliability of a received navigation message. The navigation system includes a sensor unit 220 and a map data storage unit 230 . The sensor unit 220 may include a gyroscope for detecting the traveling angle of the moving object, and various sensors, such as a speed sensor for detecting the traveling speed of the moving object. The map data storage unit 230 stores map data used for searching the driving route of the mobile ...

Abstract

A navigation system, and a method for guiding a moving object having the navigation system, include a control unit which determines a current position of the moving object and whether the moving object has arrived at a guide point of a guide target. The control unit provides the drive path based on the current position of the moving object. Upon arrival of the moving object at the guide point, a first turn guide icon and a second turn guide icon are determined for the guide target, wherein the first turn guide icon and the second turn guide icon collectively represent suggested vehicle operations at the guide point and a drive direction at a position of the guide target from a plurality of previously stored turn guide icons. The guide icons are sequentially displayed relative to the drivepath throughout the vehicle operation at the guide point.

Description

technical field [0001] The invention relates to a navigation system and a method of guiding a moving object through a driving route within the navigation system. Background technique [0002] Traffic congestion and other stresses on infrastructure have also increased due to the increase in the number of various moving objects such as motor vehicles on roads and highways. Specifically, the number of vehicles has increased far more rapidly than the actual increase and improvement of the supporting infrastructure. Thus, navigation systems in vehicles and other moving objects provide a means of avoiding or reducing traffic congestion. [0003] The navigation system detects a current location using navigation messages transmitted from a plurality of GPS (Global Positioning System) satellites and moving state detection signals detected by a plurality of sensors such as gyroscopes, speed sensors, etc. provided to corresponding moving objects. If the current position of the mobile...
