Abstract
A headlamp leveling device and a headlamp leveling method. The headlamp leveling device may include a control voltage generator that generates a control voltage based on a width of a pulse, a control integrated circuit (IC) that controls a rotation direction of a motor by comparing a voltage level of a feedback voltage with a voltage level of the control voltage, a shaft position detector that generates a voltage corresponding to a position of the shaft moving with rotation of the motor, and a feedback voltage generator that generates the feedback voltage based on a voltage generated to correspond to the position of the shaft.
