An apparatus for automatically controlling an irradiation angle of a head lamp is provided to reduce an error of a proceeding direction and an output value of a sensor by including a variable torque sensor. A torque sensor(110) is mounted on a steering column and senses the torque applied to a rotation axis inside the column. An electronic control unit(130) automatically controls the irradiation angle of a head lamp(120) according to the torque sensed in the torque sensor. A first step motor and a second step motor rotate the head lamp within a predetermined angle range according to the control of the electronic control unit. A power supply unit(160) supplies the power to the torque sensor, the electronic control unit, and the first and second step motors. |
