Abstract
A head lamp device for a vehicle capable of changing a lighting region in front of the vehicle in rightward and leftward directions is provided. The device comprises a head lamp, a lighting region changing mechanism for changing the lighting region of the head lamp, a right wheel speed sensor for detecting a rotational speed of a right wheel, a left wheel speed sensor for detecting a rotational speed of a left wheel, a lighting angle calculating mechanism for calculating a lighting angle of the head lamp from the right and left wheel rotational speeds detected by the right wheel speed sensor and the left wheel speed sensor respectively, and a control mechanism for controlling the lighting region changing mechanism on the basis of the lighting angle calculated by the lighting angle calculating mechanism to change the lighting region.
