A collision predicting apparatus detects subject targets present in the traveling course of the own vehicle by using the relative distance and the relative velocity, etc. The apparatus also calculates the predicted collision time of each subject target on the basis of the relative distance and the relative velocity. The apparatus also detects the relative lateral position of each subject target, and corrects the relative lateral position. The apparatus then executes a collision-predicted target selecting routine, in which the predicted collision time of each subject target that does not meet a predetermined condition is set at a predetermined maximum value. The apparatus selects a subject target that meets the predetermined condition as a collision subject target, and predicts whether the collision subject target will collide with the own vehicle.

What is claimed is: 1. A collision predicting apparatus, comprising:a subject target detector portion that detects a plurality of subject targets which exist in a course of the vehicle and which have a possibility of colliding with the vehicle;a relative quantity detector portion that detects a relative quantity between the vehicle and each of the subject targets detected by the subject target detector portion;a collision time calculator portion that predicts and calculates a collision time of each of the subject targets until a collision with the vehicle, by using the relative quantity between the vehicle and each of the subject targets detected by the relative quantity detector portion;a collision subject target selector portion that selects a collision subject target having a high possibility of colliding with the vehicle based on at least the collision time of each of the subject targets calculated by the collision time calculator portion;a collision predictor portion that predicts a collision between the collision subject target selected by the collision subject target selector portion and the vehicle by using the collision time of the collision subject target;a relative lateral position calculation portion that calculates a relative lateral position between the center axis of the vehicle and a part of each of the subject targets, wherein the relative lateral position is calculated based on the assumption that the vehicle is moving linearly relative to the subject targets;a curvature estimating portion that estimates a radius of a curvature along which the vehicle is running;an estimate relative lateral position calculation portion that calculates an estimated relative lateral position by correcting the relative lateral position calculated by the relative lateral position calculation portion based on the radius of the curvature estimated by the curvature estimating portion; andwherein the collision subject target selector portion excludes the subject targets from the collision subject target if at least one of the relative lateral position and the estimated relative lateral position is greater than a predetermined distance.
