摘要： The invention relates to a method for determining the course of another vehicle (25) in relation to one's own vehicle (23) by measuring the position of the other vehicle in relation to one's own vehicle by means of a transmitter/receiver system, such as a radar system. The method permits course determination both on straight and on bend segments. According to the method, the side location (d) of the other vehicle and one's own vehicle is determined at a position where the other vehicle is level with one's own vehicle, by moving the front vehicle backwards in time and/or moving the rear vehicle forwards in time, on the basis of position measurements of the position of the other vehicle. The side location of the other vehicle is compared with the side lcoation of one's own vehicle, by which means a measure of the discrepancy between the course of the other vehicle and the course of one's own vehicle is obtained. According to the invention, the position where the other vehicle is level with one's own vehicle is determined on the basis of the inertial speed vector of the other vehicle (25) at one or more points in time.
