DESIGN OF AUTOMATIC HIGHT-LOW BEAM CONTROL SYSTEM ON AUTOMOBILE

Car lighting system is a necessary means that helps drivers to observe in limited visibility conditions, the lighting system is also used to inform the movement situation so that people around can recognize in the night. In addition, the system also has the function of displaying  the automobile operating parameters to the driver through the tableau panel and illuminating the space in the automobile. In cars, in order for the lighting system to work, the driver must turn on the light switch and make a continuous transition between hight beam and low beam when the car is operating in the city or when there is a vehicle moving in the opposite direction. To reduce unnecessary operations when controlling the lighting system, it is necessary to have a design which installed automatic hight-low beam control system. The paper presents the design, calculation and installation of electrical circuits that control the automatic hight-low beam transition on automobile by LabVIEW software and applies this experiment on a real model.
