Navigation device, route guidance method, and program

摘要

Disclosed is technology for providing guidance in a manner that facilitates travel along a guidance route when there is a road which has a carpool lane. A navigation device (100) is provided with: a current-location calculation means for calculating the current location of a moving body; a recommended route search means for searching for a recommended route to a destination; a guidance-point setting means for setting a guidance point in the recommended route; and a guidance information notification means for notifying predetermined guidance information when a moving body reaches a set guidance point. When predetermined conditions are fulfilled, the guidance-point setting means sets in a road which has a carpool lane a guidance point for notifying information for guidance from said road to a branch road, before the guidance point that would be set in a road that does not have a carpool lane.

主权项

1. A navigation device comprising:
a current position calculation unit configured to calculate a current position of a moving object, a recommended route search unit configured to search for a recommended route to a destination, a guidance point setting unit configured to set a guidance point, at which guidance information to guide the moving object is output, on the recommended route a first distance before a point where guidance becomes necessary, and a guidance information announcing unit configured to display on a screen or output from a speaker the guidance information, when a moving object reaches the set guidance point, wherein, when a distance between a leaving point where the moving object should exit carpool lanes and a branching point where a road with carpool lanes branches off is shorter than a predetermined distance, the guidance point setting unit sets the guidance point to a second distance that is shorter than the first distance before the point where guidance becomes necessary.
