ABSTRACT:
A auto-leveling system for vehicle headlamp comprises a headlamp an optical axis L of which is tilted vertically by a drive of a motor, a control unit16for controlling the drive of the motor10, a vehicle pitch angle sensing means14, and a headlamp lighting switch11, whereby the control unit16controls the drive of the motor10based on a sensed pitch angle such that the optical axis of the headlamp is always set to a predetermined tilted state with respect to a road surface when the headlamp lighting switch is in an ON state, wherein the system has a daytime running light lighting deciding function, and the control unit16controls the drive of the motor10so as to fix the optical axis L of the headlamp at a frontal lower limit position when the headlamp lighting switch11is in an OFF state and a daytime running light is turned on. Thus, the drive of the motor10in a daytime running is eliminated and a load applied to the motor10is reduced.
