An optical axis control apparatus includes an optical axis controlling unit for calculating a pitch angle using output values from an acceleration sensor provided in a vehicle and controlling, using the pitch angle, optical axis angles of headlights provided in the vehicle, during stop of the vehicle; and a rolling motion determination unit for determining, when the vehicle has started traveling, whether there has been a rolling motion during the stop of the vehicle. When the pitch angle has been changed during the stop of the vehicle due to loading or unloading of baggage or a change of passengers, etc., and the rolling motion determination unit determines that the rolling motion exists, the optical axis controlling unit corrects, when the vehicle has started traveling and the rolling motion has been terminated, the changed pitch angle, i.e., the amount of change in pitch angle, using the amounts of correction set for each roll angle, and controls the optical axis angles using the corrected pitch angle, the each roll angle being obtained during stop of the vehicle.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.
