Vehicle headlamp device

There is provided a vehicle headlamp apparatus comprising: control means which is adapted to change an illumination region of a position of a detected target object following until it is calculated that a shift angle between a reference direction and a direction to the target object with respect to a headlight exceeds a maximum displacement angle which is covered by the headlight in a low beam, and which is adapted, when it is detected that a vehicle speed exceeds a predetermined threshold, to set the maximum shift angle to a small deflection angle, and to change the current lighting region to a Abblendlichtbeleuchtungsbereich, if it is calculated that the displacement angle exceeds the set on the small deflection angle maximum displacement angle.
