DRIVE SUPPORT APPARATUS
First Claim
1. A drive support apparatus disposed in a self-vehicle and performing a drive support control for supporting a drive operation of a driver in the self-vehicle, the drive support apparatus comprising:
- a controller, the controller configured to includea self-vehicle positioner sequentially determining a current position of the self-vehicle having the drive support apparatus by receiving a navigation signal from a navigation satellite of a satellite navigation system, and obtaining current position information from the received navigation signal;
a road determiner sequentially determining a currently-traveled road that is currently traveled by the self-vehicle, based on a matching result of a map matching that places (i) the current position of the self-vehicle determined by the self-vehicle positioner on (ii) one road link in a road map that represents (a) each road by using a link, and (b) each intersection by using an intersection node;
a node determiner sequentially determining a first intersection node on the currently-traveled road determined by the road determiner, the first intersection node first encountered by the self-vehicle in a travel direction from the current position of the self-vehicle;
a priority determiner sequentially determining whether the currently-traveled road determined by the road determiner is, against an intersecting road, a priority road at the first intersection node determined by the node determiner;
a drive support controller performing a suppressed drive support control, when the priority determiner determines that the currently-traveled road is a priority road, the suppressed drive support control being suppressed from a normal drive support control that is performed when the priority determiner determines that the currently-traveled road is a non-priority road; and
an area setter setting a determination-kept-unchanged (D-K-U) area, based on the intersection node determined by the node determiner, whereinthe priority determiner keeps the determination of the priority road unchanged from a determination result made before the self-vehicle enters the D-K-U area, upon determining that the current position of the self-vehicle is inside the D-K-U area.

Abstract
A drive support apparatus includes a self-vehicle positioner determining a current position of a self-vehicle, a road determiner determining a currently-traveled road of the self-vehicle by map-matching the current position on a link of a road map, a node determiner determining a first intersection node on the currently-traveled road, a priority determiner determining whether the currently-traveled road is a priority road at the first intersection node against an intersecting road, a drive support controller performing a suppressed drive support control when the priority determiner determines that the currently-traveled road is a priority road, and an area setter setting a determination-kept-unchanged (D-K-U) area based on the intersection node. Based on the above, the drive support apparatus can accurately determine whether a current situation is a drive support suppression situation in which the drive support to a driver should not be provided.
