Problem. Checking the brake system of a vehicle is crucial in terms of assessing its operational safety, and performance indicators and permissible modes are determined by the state standards of Ukraine. However, there are challenges related to the accuracy and objectivity of evaluating the braking efficiency of a car. The coefficient of adhesion between the wheel and the road surface is the primary factor that significantly affects the braking dynamics of a vehicle. This coefficient constantly changes due to various factors such as road surface conditions, tire design and properties, tire effectiveness, and car speed. Assessing the impact of these factors on a car's braking performance is difficult. Goal. The aim of this study is to experimentally determine the influence of tire properties on vehicle braking efficiency by conducting a multifactorial experiment on cars of different brands with different types of tires. Methodology. The study employs the method of conducting braking tests under road conditions using the necessary equipment. Statistical data on braking efficiency parameters were collected from cars equipped with different tire brands. Experimental tests were conducted on Mazda 323F and Hyundai Elantra cars, using tires from various manufacturers such as Sava, Tigar, Nokian, and MICHELIN. The tests were performed on asphalt-concrete surfaces under dry and wet conditions, and the braking efficiency indicators were measured. Originality. The experiment revealed that the quality of the rubber used in car tires has a significant impact on their braking efficiency within a wide range. The deceleration of a category М1 vehicle can exceed the minimum requirements for braking efficiency, established by national and international standards, by 29-67%, depending on the tire brand. This research presents prospects for further development of experimental and statistical studies in this field, aiming to provide a better understanding of car braking efficiency parameters based on tire quality. Practical Value. The data obtained from this study are of practical importance for evaluating the effectiveness of car braking during expert investigations of traffic accidents. This enables experts to draw more objective conclusions about the accident process and determine the driver's ability to avoid such incidents.

One of the promising trends in modern training is the maximum immersion of students in educational material in order to ensure the immersiveness of education. To increase the efficiency of the educational process, new information technologies are being actively introduced. Such technology is augmented reality (AR). Augmented reality allows you to implement this approach using smartphones, tablets and computers. Currently, two approaches are used: marker and marker-free technology. The use of augmented reality is possible both online and offline. Materials for the implementation of this technology in the educational process are usually prepared by IT companies using languages and programming tools of their own development, which somewhat reduces the availability of technology for ordinary users (both teachers and students). The purpose of this study is to analyze the reasons that limit the spread of augmented reality technology in the educational process and to offer own solution to this issue. On the example of using the Aurasma platform, an option of introducing augmented reality technology into process of training of operators of multi-purpose armored military vehicles is proposed. The proposed option of using public software and devices for the development and application of the information system allows students to study the device, the principle of its operation, features of diagnostics and maintenance of systems, units and components of the military vehicle. The proposed technology of augmented reality allows to increase the level of remote learning of information material by 8.2%, as well as to ensure the formation of highly qualified bachelors, masters or doctors of philosophy upon implementation of remote learning technologies in higher education. With the development of information transmission technology 5G and above, the need for such information systems will grow. The decrease in the cost of smartphones, tablets and other devices, such as augmented reality glasses, will also give an additional impetus to the development of this technology.
