In controlling a vehicle headlight that has the ADB (Adaptive Driving Beam) function, low beams and high beams are appropriately controlled even when a vehicle ahead is making a turn. A vehicle headlight control device detects a turning motion in accordance with a change in an open angle of the vehicle ahead that can be obtained by monitoring lights of the vehicle ahead, and controls the headlight such that, before switched to high beams, the headlights continue a low-beam illumination for a prescribed delay time with respect to an area where the turning motion was detected immediately before the vehicle ahead went to a non-detected state. The vehicle headlight control device may be configured to determine the delay time based on an own vehicle speed and an open angle immediately before occurrence of the non-detected state. |
