VEHICULAR HEADLIGHT APPARATUS

摘要

The vehicular headlight apparatus includes a control means configured to change a light illumination area following a position of a detected target object until a shift angle between a reference direction and a direction to the target object with respect to a headlight is calculated to exceed a maximum limit shift angle, and configured to, when a vehicle speed is detected to exceed a predetermined threshold value, set the maximum limit shift angle to a small deflection angle, and change the present light illumination area to a low-beam light illumination area covered by the headlight in a low-beam state if the shift angle is calculated to exceed the maximum limit shift angle set to the small deflection angle.

1. A vehicular headlight apparatus comprising:
a headlight which illuminates ahead of a vehicle; changing means for changing a light illumination area of the headlight; recognition means for recognizing ahead of the vehicle; analyzing means for calculating a position of a given target object based on data outputted from said recognition means; vehicle speed detecting means for detecting a speed of the vehicle; and control means for controlling the changing means, when the given target object is detected, said control means working to change the light illumination area through said changing means in order to minimize dazzling to the given target objet based on analysis results derived by said analyzing means, wherein when the speed of the vehicle, as detected by said vehicle speed detecting means, exceeds a given threshold value, said control means changes the light illumination area to a low-beam light illumination area earlier than when the speed of the vehicle is lower than the given threshold value.
