Abstract

The invention provides navigation devices capable of guiding in a way of finding a destination out successfully, navigation methods and programs. The navigation devices comprise: a vehicle location acquisition unit for acquiring a vehicle location, a map information storage unit for storing map information including road width information, a destination setting unit configured to set a destination, a route search unit for searching for a route to the destination based on the map information, a route guidance unit for performing route guidance based on the route; and a last branch point acquisition unit for acquiring a last branch point on the route, wherein based on a road width of an entering link entering the last branch point and a distance from the last branch point to the destination, the route guidance unit determines a point at which last guidance to the destination is to be given.

Description

technical field [0001] The present invention relates to a navigation device, a navigation method, and a program for route guidance. Background technique [0002] So far, various proposals have been made regarding techniques for guiding a route from the position of the own vehicle to the destination. [0003] For example, there is a navigation device configured in such a way that the arrival judgment distance for judging arrival at the destination is changed according to the road type of the road connected to the destination, and when the distance from the vehicle position to the destination is less than or equal to the arrival judgment distance , to provide guidance indicating that the destination has been reached (for example, refer to Patent Document 1). [0004] Patent Document 1: Japanese Patent Laid-Open No. 2005-30864 [0005] However, according to the above-mentioned navigation device described in Patent Document 1, when the road type of the road connected to the de...
