PROBLEM TO BE SOLVED: To estimate the course of an object present in front of one's own vehicle with high accuracy even when the steering angle of the one's own vehicle is suddenly changed. SOLUTION: As regards a course estimating method based on the past positional history of an object and a course estimating method based on the relative position of the object and the traveling state of the one's own vehicle, a method to be used when estimating a course according to whether the absolute speed of the object is high or low is determined. The determined course estimating method is used to estimate the relative course of the object. COPYRIGHT: (C)2007,JPO&INPIT
