The theoretical foundations and practical aspects of the application of the adjustment headlights military automotive technology. The analysis of known approaches to building systems adjusting headlights. The structure of the system, its mathematical analysis conducted and compiled the relevant algorithms. Systems of passive and active safety, signaling and warning systems, driver's state control, vehicle adaptation to traffic conditions acquire wide development. The quality of the road lighting conditions is significantly affected by the high-quality performance of tasks according to its purpose and on the safety of traffic at night. Adaptive lighting systems allow the lights to be rotated only in the horizontal plane. During the movement of military vehicles on roads with a slope and on roads in mountainous terrain, it is necessary to turn the lights, both in horizontal and in vertical planes. Modern microcontrollers allow you to adjust the headlights automatically, without the participation of a person, which prevents the driver from being distracted from the control process and improves visibility while driving both for him and for crew members. The application of the correction of headlamps on military automotive equipment is especially relevant for units of the Armed Forces of Ukraine, which often have to conduct hostilities at night in the course of an anti-terrorist operation. In this study, algorithmic velocity estimation is used for the measurement of positions. Together with the sensors, the body position on the formation of input signals is fed by the output of the steering wheel positioner, as well as the angles of rotation of the headlights, which can be rotated horizontally and vertically. The peculiarity of the headlight control system in the vertical direction is the need for high-speed system with uneven road. The formation of input signals for these sensors are scalable and buffer amplifiers, which coordinate the signals of the sensors by level and by power with the inputs of the microcontroller. Generation signals arrive at a multichannel analog digital converter built into the microcontroller.References
