POSITION DETECTION METHOD AND POSITION DETECTION APPARATUS FOR PRECEDING VEHICLE AND DATA FILTERING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a position detection method and a position detection apparatus which have improved calculation accuracy of the position data of a preceding vehicle.

SOLUTION: A method for detecting the position of a preceding vehicle 2 in relation to one's own vehicle 1 comprises: a step of acquiring a primary data set having vehicle range information riand lateral position information Li, Ri; a step of linear regression processing for performing linear regression processing on the vehicle range information riof the primary data set, and acquiring a secondary data set having the vehicle range information riwherein the deviation with the acquired linear regression line is at or below a prescribed threshold value and corresponding lateral position information Li, Ri; a step of clustering processing (S6) for performing clustering processing on the lateral position information Li, Riin the secondary data set, and acquiring a tertiary data set having lateral position information Li, Riin the largest cluster and corresponding vehicle range information ri; and a step of position information calculation (S7) for calculating the vehicle range and lateral position at the present time t0using the tertiary data set.
