a node determiner configured to determine a first intersection node on the currently-traveled road, the first intersection node representing a first intersection including at least the currently traveled road and an intersecting road;
an area setter configured to determine a closed-shaped determination-kept-unchanged (D-K-U) area around the first intersection node;
a priority determiner configured to determine a priority of the currently-traveled road at the first intersection node before the subject vehicle enters the D-K-U area, the priority determined as either a priority road or a non-priority road; and
a drive support controller configured to control the drive support control of the subject vehicle in the D-K-U area based on the priority of the currently-traveled road, whereinthe currently traveled road is represented as a first road link by the map information and the intersecting road is represented as a second road link by the map information, and whereinthe D-K-U area surrounds the first intersection node and includes a portion of the first road link and the second road link within the D-K-U area, and whereinwhen the subject vehicle enters the D-K-U area, the priority determiner maintains the priority of the currently-traveled road determined before the subject vehicle enters the D-K-U area, and whereinwhen the priority of the currently-traveled road is determined as the priority road, the drive support controller suppresses the drive support control when the subject vehicle is in the D-K-U area, and whereinwhen the priority of the currently-traveled road is determined as the non-priority road, the drive support controller performs the drive support control when the subject vehicle is in the D-K-U area.

Abstract
A drive support apparatus includes a positioner determining a current position of a subject vehicle, a road determiner determining a currently-traveled road of the subject 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.
