Abstract

The present disclosure relates to a leveling controller device lamp and a control method thereof, and specifically, to a vehicle lamp leveling control device and a control method thereof, the device comprising: at least one acceleration sensor configured to detect an acceleration of a vehicle in at least one direction; a wheel speed sensor configured to detect a wheel speed; a lamp configured to emit light; a driving unit connected to the lamp to adjust a direction of the light; and a controller configured to calculate a dynamic angle value with respect to a road surface when the vehicle accelerates or decelerates when the vehicle is traveling, and calculate a first static angle value based on the dynamic angle value of the vehicle, and calculate a second static angle value and a road grade value of a road where the vehicle is located when the vehicle is stopped, the direction of light emitted forward by the lamp is then controlled based on the first static angle value or the second static angle value.

Description

[0001] Cross-references to relevant applications [0002] This application claims the interest in the Korean Patent Application No. 10-2020-0149785 filed with the Korean Intellectual Property Office on November 11, 2020, the disclosure of which is incorporated herein by reference. Technical field [0003] The present invention relates to a leveling control device fora vehicle lamp and a control method thereof. Background [0004] The statements in this section only provide background information related to the present invention and do not necessarily constitute prior art. [0005] The vehicle is equipped with lights, each of which has a lighting function to easily identify objects around the vehicle when driving at night. [0006] Among these lights, when the vehicle is driving at night or in a dark place such as a tunnel, the headlamps have the basic function of ensuring the driver's forward vision by emitting light in the same direction as the vehicle. In general, headlamps are ...
