Abstract
An apparatus for automatically adjusting a direction of a headlight of a vehicle includes a steered angle sensor detecting a steered angle of a steering wheel of a vehicle, a vehicle speed sensor detecting a speed of the vehicle, a control unit performing a swivel control by which the direction of the light axis of the headlight is adjusted to a target direction depending on the steered angle and the vehicle speed, and a variance calculating device calculating a variance of the steered angle detected by the steered angle sensor. The control unit halts the swivel control unit when the variance calculated by the variance calculating device exceeds a predetermined threshold.
