Abstract
A traffic lane acquisition section obtains traffic lane information that includes the road shape of a host-vehicle lane, from road map information, based on the detected position of a host vehicle, expressed by position information obtained by a host vehicle position acquisition section. Based on detected positions of traffic lane identification-use objects, contained in object information obtained by an object acquisition section, a lane boundary line identification section identifies lane boundary lines. A region estimation section estimates a displacement-possible region of the host-vehicle lane ahead of the host vehicle, based on the lane boundary lines that are obtained by the lane boundary line identification section. If a predetermined lane reliability condition is not satisfied for the lane boundary lines, then the accuracy of estimating the displacement-possible region is updated by using the road shape of the host-vehicle lane from the traffic lane information obtained by the traffic lane acquisition section.
