NAVIGATION DEVICE

摘要

Disclosed is a navigation device which extracts an entrance and exit section which exists ahead of a vehicle and in which a vehicle is permitted to make a lane change between an HOV lane and a normal lane on the basis of information about the position of the vehicle and map data in which the HOV lane and the normal lane are defined by a single link, extracts a branch point on the HOV lane existing ahead of the vehicle on the basis of the map data and the position information, determines a guidance time for the extracted entrance and exit section, and another guidance time for the branch point, and provides guidance notifying that the vehicle can exit the HOV lane or guidance notifying that the vehicle can enter the HOV lane at the guidance time, or provides guidance on the branch at the other guidance time.

主权项

1. A navigation device comprising:
a memory device that holds a computer program; and a processor that executes the computer program read out from the memory device, wherein the computer program is configured to perform a process of:
acquiring map data in which a single link represents a plurality of lanes of a road including at least one special lane and a plurality of normal lanes, the map data being a map data in which entrance and exit between a particular special lane of the at least one special lane and one of the normal lanes which is adjacent to the particular special lane are permitted only in a predetermined permitted section;extracting an entrance and exit section of the road which exists ahead of a vehicle and in which the vehicle is permitted to make a lane change between the particular special lane and the adjacent normal lane on a basis of the acquired map data and position information about the vehicle;extracting a branch point on the at least one special lane which exists ahead of the vehicle on a basis of the acquired map data and the position information about the vehicle;determining a guidance time for a lane changing permitted section defined by the extracted entrance and exit section, and another guidance time for the extracted branch point, the both guidance times being determined such that a guidance time during travel on the at least one special lane is later than a guidance time during travel on the normal lanes; andproviding, at the determined guidance time, exit guidance notifying that the vehicle is permitted to exit the particular special lane onto the adjacent normal lane or entrance guidance notifying that the vehicle is permitted to enter the particular special lane from the adjacent normal lane, or branch guidance on the branch point on the at least one special lane.
