A headlight control apparatus for controlling an irradiation angle of a headlight of a vehicle based on a pitch angle includes a height sensor and a camera. The height sensor detects a displacement amount of a spring upper member with respect to a rotation axis of the vehicle as a contraction length. The apparatus obtains an infinity point correlation value based on an infinity point position in the image obtained by the camera in a vertical direction. When a predetermined condition is satisfied, the apparatus obtains a standard pitch angle based on the contraction length and obtains the infinity point correlation value at the present time as a standard infinity point correlation value. When the condition is not satisfied, the apparatus obtains the pitch angle based on the standard pitch angle, the standard infinity point correlation value, and the infinity point correlation value at the present time.

A vehicle headlamp aiming adjustment system includes a headlamp controller configured to adjust an emission direction of light emitted from a headlamp; a sensing unit configured to measure a sensing area on a ground and measure a change of the sensing area; and a controller configured to receive information about the sensing area measured by the sensing unit, compare the measured sensing area with a pre-stored reference area, and transmit a control signal to the headlamp controller such that the emission direction of light is adjusted in accordance with a change of the sensing area when the sensing area is different from the reference area. The above-describe vehicle headlamp aiming adjustment system can check an emission area of light of a headlamp and secure the driver's field of view by correcting the emission area.
