Abstract
An absolute pitch is outputted from an inclination sensor. A gradient related quantity is outputted from a gradient related quantity detection sensor for detecting a gradient related quantity that can specify a gradient of a road surface. The absolute pitch angle and the gradient related quantity are acquired by a vehicle headlight control apparatus. Based on the absolute pitch angle and the gradient related quantity, a pitch angle of a vehicle with respect to a road surface is calculated by the vehicle headlight control apparatus. Based on the pitch angle, an optical axis direction of the head lamp is controlled by the vehicle headlight control apparatus.
