Abstract: A method and an apparatus are provided to recognize a shape of a road on which a vehicle is traveling. Road edge shapes on a left side and a right side of the vehicle are recognized, from positions of roadside objects detected based on detection information from an on-board radar. Lane shapes that are shapes of lane boundary lines on the left side and the right side of the vehicle are recognized, from positions of lane boundary lines detected based on an image captured by an on-board camera. For each of the left side and the right side, such that the recognized road edge shape and the recognized lane shape are compared with each other, and the road shape is identified based on the comparison results.

Abstract: This disclosure provides as an aspect a course estimator having a curvature radius estimator, a calculator and a determination section. The curvature radius estimator obtains first information on a forward traveling path ahead of a vehicle in a traveling direction of the vehicle at different time points and estimating, on the basis of the first information obtained repeatedly, each curvature radius of the forward traveling path at a respective time. The calculator calculates change information indicating magnitude of time change in curvature radius of the forward traveling path on the basis of the estimated curvature radiuses of the forward traveling paths. The determination section determines whether or not there is a changing point where a road shape of the forward traveling paths changes on the basis of the calculated change information.

Abstract: A driving support apparatus installed in a host vehicle calculates an overlap ratio relating to a target object positioned ahead of the host vehicle within the same traffic lane, as the ratio of the width of the target object to its lateral distance from a lane marker line of the traffic lane, and also detects the motion condition of the object (i.e., stationary, moving towards, or in the same direction as the host vehicle, or moving laterally with respect to the forward direction of the host vehicle). An amount of compensation for retarding or advancing the commencement of a collision avoidance operation by the driving support apparatus is determined based on the overlap ratio and/or the motion condition of the target object.
