Abstract
A head lamp device for a vehicle capable of changing a lighting region in front of the vehicle in right and left directions, in which change of the lighting region is suppressed so as not to give the driver a sense of incongruity when a steering wheel is operated in one direction and then rapidly in the other as in case of counter-steering. The device comprises a lighting region changing mechanism for changing the lighting region of the head lamp; a steering angle sensor for detecting a steering angle; a turning movement detector for detecting a turning movement of the vehicle body in right and left directions; a first lighting angle calculating mechanism for calculating a first lighting angle based on the steering angle detected by the steering angle sensor; a second lighting angle calculating mechanism for calculating a second lighting angle based on the turning movement detected by the turning movement detector; a lighting angle deciding mechanism for deciding a final lighting angle from the first lighting angle and the second lighting angle; and a controller for controlling the lighting region changing means to change the lighting region on the basis of the final lighting angle.
