Abstract

Beam control over headlamps is performed with the arriving position, a predetermined time later from the present time, as a target position. At this time, the radius of curvature of a traveling road ahead of a vehicle is calculated on the basis of data from a navigation unit, and the arriving position of one's own vehicle is estimated on the basis of an advisable vehicle speed corresponding to the radius of curvature. Thus, the arriving position of one's own vehicle can accurately be estimated by taking into consideration variation in vehicle speed that is likely to occur in the near future.
