Problems solved by technology

Therefore, in the traditional driving direction decision, even if the road ahead is identified as going straight ahead within the user's line of sight, if the road ahead is not within a predetermined angle of the driving direction, the navigation system will recognize the driving direction as turning left or right, This frequently leads to a phenomenon that the displayed path does not match the real path seen by the naked eye, and becomes one of the factors that confuse the driver and endanger safe driving

Abstract

An apparatus and method for determining a driving direction of a navigation system are provided. The apparatus includes: an input unit for receiving longitude and latitude coordinates, a road type, and a number of lanes; and a traveling direction processor for determining a current road on which the own vehicle is located using point information received through the input unit. When the road ahead is of the same type and the same lane, the driving direction is determined as straight forward, and when the current road and the road ahead are determined to have different types and lanes from each other, the driving direction is determined as a left turn / right turn using a convex hull algorithm and straight ahead; and an output unit for displaying on a screen which driving direction of the road is a left turn / right turn and straight ahead.

Description

technical field [0001] The present invention relates to a navigation system, and more particularly to a device and method for determining the driving direction of the navigation system, wherein when performing a navigation route search, it determines the left turn / Turn right or go straight, and can clearly show the road ahead whether to turn left / right or go straight, allowing users to drive stably. Background technique [0002] In a conventional navigation route search method, a convex hull algorithm is used to determine left / right turns or straight forward according to the relationship between roads associated with vehicle positions. [0003] The convex hull algorithm is one of the optimal two-segment methods proposed by Golden and Stewart, and a path between two points is obtained using this convex hull algorithm. [0004] The convex hull algorithm is based on the assumption that there are three points (node ​​1, node 2 (intersection) and node 3), the ego vehicle is on ...
