Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0025] FIG. 1 is a diagram showing a navigation system according to an embodiment of the present invention.

[0026] In the figure, 10 is an automatic transmission control unit as a power train control unit, and the automatic transmission control unit 10 is a power transmission that changes gears according to a predetermined gear ratio, that is, for an automatic transmission without The variable speed machine (CVT), the stepped speed changer (automatic transmission, automatic transmission), and the electric drive device are controlled.

[0027] In addition, 14 is an information terminal, for example, a navigation device which is an in-vehicle device mounted on a vehicle, 63 is a network, and 51 is an information center which is an information provider. A navigation system is constituted by the above-mentioned automatic transmission control unit 10, the naviga...

Abstract

A route guidance system includes a current position detection portion; a route search processing portion that searches for a specified route to a destination; a guidance intersection setting processing portion that sets a guidance intersection based on the specified route; a recommended lane computation processing portion that computes the recommended lane on each road on the specified route, based on the specified route; a recommended lane change point detection processing portion that detects a recommended lane change point, where a recommended lane changes, between the current position and the guidance intersection; and a recommended lane change notification processing portion that, before the host vehicle arrives at the recommended lane change point, notifies the driver that the recommended lane will change. The recommended lane change point is detected, and the driver is notified, before the host vehicle arrives at the recommended lane change point, that the recommended lane will change. Therefore, the driver is not confused when being guided to drive the host vehicle in the recommended lane.

Description

technical field [0001] The invention relates to a path guidance system and a path guidance method. Background technique [0002] In the past, in a navigation device, for example, GPS (Global Positioning System) is used to detect the current position of the vehicle of the own car, that is, the current place, map data is read out from the data recording unit, and a map screen is formed on the display unit. Displays the current location of the vehicle, a map around the location of the vehicle, and the like. Therefore, the driver as the operator can drive the vehicle according to the position of the vehicle displayed on the map screen and the like. [0003] Also, if the driver inputs a destination and sets a search condition, a route search process can be performed based on the search condition, and a route from the departure point indicated by the current location to the destination can be searched according to the above-mentioned map data. In this way, the searched route, th...
