The purpose of the research is the analysis of existing systems for monitoring the driver's condition using an Android mobile application to increase the level of active safety with the development of an algorithm for monitoring the driver's condition. At the same time, such parameters as turns and tilts of the head, duration of eyelid blinking, yawning are taken into account. As a result, the state of drowsiness, impaired attention, and drunkenness of the driver is analyzed. The article analyzes the methods of monitoring the dangerous condition of the driver during the movement of the vehicle. The list of programs used in this case is given. The Drive Safely mobile application was chosen for the research, which is based on monitoring the condition of the driver's eyes and mouth. Based on research, eye PERCLOS should not exceed 28% and mouth PERCLOS should not exceed 30%. An algorithm for recognizing emergency situations in the vehicle cabin based on the image of the driver's eyes and mouth from the front camera of a smartphone has been developed.

М.; Коломієць, А. Б.; Котовський, О. О.; Kandiak, N.; Kolomiiets, А.; Kotovskii, O.Для дослідження явищ під час утворення об’ємної форми тари методом одночасного сгинання клапанів розгортки з гофрованого картону створено стенд. Привод інструментам, що надається від крокового двигуна, може бути як рівномірним, так і за певними законами руху. Розглянуто електронні пристрої керування двигуном та вимірювальним модулем, а також спеціалізоване програмне забезпечення. Створено програму керування швидкістю вала двигуна під час робочого і зворотного ходу. The improvement of the equipment for the forming of the volumetric shape of packages and containers requires a detailed study of the phenomena in the folding process of sheet material with a complex structure (corrugated cardboard). A stand has been created to study process parameters, successful research on which should be provided by programmed control of tool movement and synchronous transfer of measured data to a computer for further processing. Moving tools (punches) are driven by a stepper motor. The movement of the stepper motor shaft is programmed to obtain both a uniform movement and movement according to a certain law, which can be different for the working and reverse moves. Forces are measured by a strain gauge clamp, the signal from which is also transmitted to external devices for visualization and processing. The basis of the motor control and measurement unit is the Arduino Uno microcontroller, which, together with the Arduino Nano controller and the analog-to-digital converter, significantly expands the functionality of the stand. The diagram and operation of the created control and measurement unit is described. A special program has been created to study the geometric, kinematic and power parameters of the process, the possibility of quickly changing the law of motion, providing various ratios and laws of motion to the working and reverse motion of punches. The laws of motion for the motor shaft are presented in it in the form of matrices of values, which are accessed before starting the measurement from the stand control panel. The parameters of the process of simultaneous folding of corrugated cardboard, which were investigated using a stand, are described. The developed measurement technique and means of controlling the movement of the stepper motor of the tool drive allowed to estimate the maximum effort, the nature of the change during the work cycle, to compare different types of material and folding modes. The result of determining the optimal parameters of the process of operational packaging & container formation is the creation of recommendations necessary for the design of modern energy-saving equipment.Item Забезпечення якості роботи підприємств автомобільної інфраструктури з позиції ергономіки(ЦНТУ, 2022) Чорна, О. В.; Прогній, П. Б.; Попович, П. В.; Шевчук, О. С.; Фалович, Н. М.; Буряк, М. В.; Chorna, O.; Prohnii, P.; Popovich, P.; Shevchuk, O.; Falovych, N.; Buryak, M.В статті визначено важливу роль автомобільної інфраструктури в транспортній системі, ідентифіковано її складові, окреслено напрями застосування ергономіки в системі автомобільних перевезень, розкрито багаторівневу структуру в системі «водій-автомобіль-дорога-автомобільна інфраструктура», в межах системи встановлено спіральний характер еволюції її елементів, яка передбачає постійне повторення дій та заходів, спрямованих на покращення умов праці, що відбувається щоразу на вищому рівні, обґрунтовано, перспективні напрями розвитку автомобільної інфраструктури. The article identifies the important role of automotive infrastructure in the transport system, identifies its components, outlines the application of ergonomics in the road transport system, reveals the multilevel structure in the system "driver-car-road-car infrastructure", within the system established the spiral nature of its elements. which provides for the constant repetition of actions and measures aimed at improving working conditions, which is happening at the highest level, justified, promising areas of automotive infrastructure. An integral part of road transport is the road infrastructure, which provides favorable conditions for the proper implementation of transport companies' mission. Despite the fact that the road infrastructure is not directly involved in transportation, its role is equally important, because it creates the minimum and additional conditions for road transport to perform its function - to ensure efficient, comfortable and safe transportation of passengers and goods. In the conditions of dynamic development, an important task of the automobile infrastructure enterprises is to establish effective system interaction by coordinating the actions of all components of road transport processes within a single system. The use of a systematic approach in this case allows to ensure the high quality of enterprises in the field by combining the production potential of man, technical means and the environment. These elements form a holistic system "man-machine-environment" (LTS) [6, p.163], which is the subject of study of ergonomic science and has significant potential in terms of improving the quality of the system. The article defines that the peculiarity of the system is its tendency to entropy, resulting in the evolution of its elements. At the same time, the improvement of one of the elements unbalances the system and leads to the evolution of its other subsystems, which again stabilizes its state, but at a higher level. It is substantiated that such development of the studied processes is characterized by a spiral tendency of development, according to which the actions and reactions of the elements of the system are constantly repeated, but each time at the highest level.
