Abstract
A vehicular headlamp apparatus includes: a headlamp that illuminates ahead of a vehicle; illumination range changing means for changing an illumination range of the headlamp; detecting means for detecting a position of a forward vehicle present in front of the vehicle; controlling means for controlling the illumination range changing means based on the position of the forward vehicle detected by the detecting means; and determining means for determining whether or not the position of the forward vehicle is within the illumination range. When the position of the forward vehicle is determined as being within the illumination range, the apparatus changes the illumination range so as to have the position of the forward vehicle fall outside the illumination range. When the position of the forward vehicle is determined as being outside the illumination range, the apparatus does not change the illumination range or performs, on the illumination range changing means, a control of suppressing change of the illumination range.
