IMPLEMENTING THE CONCEPT OF ADAPTIVE LIGHTING OF THE ROAD BY A MOTOR VEHICLE

Abstract

Background. Driving at night requires drivers to concentrate more, which leads to premature fatigue. Particular attention should be paid to reducing the glare of drivers of vehicles when oncoming cars. In this regard, an urgent task is to further improve the system of car headlights and headlight design. The purpose of the work is to improve road safety in the dark. Materials and methods. The problem of blindness is that the illumination of the roadway between oncoming cars increases inversely proportional to the square of the distance between them. Therefore, to increase traffic safety it is necessary to control the maximum level of illumination between approaching cars and to change the light intensity of their left headlights so that the illumination of the road surface between approaching cars should not exceed the limiting values. Results. The system of the head illumination of the car was designed to implement adaptive illumination of the roadway in all traffic modes of the car, which ensures safe passing of oncoming vehicles. RGB LED as a light source allows you to create different types of light distribution without using additional lights. The offered way of lens moving allows increasing the accuracy of creation of a required light distribution. Results. Adjustment of the software for stationary modes of operation when driving at a constant speed can be made on a specially equipped for this purpose site of the manufacturer's plant. Operation in transient modes is defined by time of reaction of the system as for illumination increase at approach of cars, and time of restoration of light intensity of the left headlight after driving apart as a result of sharp change of illumination of a road bed. These actions will require additional field testing in the factory laboratories. Conclusions. The proposed adaptive head lamp allows you to create the required light distribution in the modes of far, dipped and fog lights, thereby increasing the safety of road traffic.
