An azimuth of the direction of travel of the host vehicle is acquired, a radius of the road on which the host vehicle is traveling is estimated, a location of another vehicle is acquired, an azimuth of the direction of travel of the other vehicle is acquired, the other vehicle is positioned on a coordinate system, an origin of which is the host vehicle, and an axis of which is the estimated road radius in the direction of travel of the host vehicle, and determination is made on whether or not the other vehicle is on the same course as the host vehicle by taking account of the width of the course, location error, azimuth error, error in the estimated road radius, error due to drift of the vehicle, and change in the curvature of the course.
