Navigation system
First Claim
1. A navigation system, comprising:
- (a) a data storage portion containing map data;
(b) a current position detection portion that detects a current position of a host vehicle;
(c) an acceleration lane remaining distance acquisition portion that determines a distance from the current position to the end of an acceleration lane where it merges with a main thoroughfare, based on the map data and the current position of the host vehicle;
(d) a merging support guidance selection portion that selects a type of merging support guidance that will support the merging of the host vehicle from the acceleration lane into the main thoroughfare, based on information for the host vehicle in the acceleration lane, information for a vehicle on the main thoroughfare, and the distance from the current position to the end of the acceleration lane; and
(e) a guidance execution portion that executes the selected merging support guidance.

Abstract
A navigation system includes data storage that contains map data, a current position detection portion that detects a current position of a host vehicle, an acceleration lane remaining distance determination portion that determines a distance from the current position to the end of an acceleration lane where it merges with a main thoroughfare, based on the map data and the current position of the host vehicle, a merging support guidance selection portion that selects a type of merging support guidance for supporting the merging of the host vehicle from the acceleration lane into the main thoroughfare, based on information for the host vehicle in the acceleration lane, information for another vehicle so located on the main thoroughfare as to be accounted for in merging, and the distance from the current position to the end of the acceleration lane, and a guidance execution portion that executes the selected merging support guidance.

15. A navigation method for providing a host vehicle with guidance for merging into a main thoroughfare from an acceleration lane, comprising:
-
determining the current position of the host vehicle;
determining the distance in the acceleration lane between the current position of the host vehicle and the end of the acceleration lane where it merges with the main thoroughfare with reference to stored map data including information on the acceleration lane;
selecting merging support guidance based on information for the host vehicle and information for a vehicle traveling on the main thoroughfare and posing a potential obstacle to the merging; and
outputting the selected merging support guidance to the driver of the host vehicle. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
