Abstract
This invention provides a vehicle cruise control system which, during recognition of a shape of a road extending in a frontward direction of host vehicle, can calculate the road shape rapidly and accurately from a positional relationship with respect to the host vehicle. The system includes at least: a position change detector that detects, from information on the road existing in the frontward direction of the vehicle, a horizontal distance from a line segment orthogonal to a traveling direction vector of the vehicle, to a centerline of the road, the detection being conducted at a plurality of measuring points in an extending direction of the traveling direction vector; a road shape recognizer that identifies the shape of the road from data relating to linearity of changes in each of the horizontal distances, the linearity data being obtained by the position change detector; and a cruise controller that controls traveling of the vehicle according to results of the identification by the road shape recognizer.
