Problem. Increasing the active safety of automobiles remains an important issue in modern automotive engineering. This study will investigate opportunities to increase the effectiveness and scope of automotive active safety measures. Current active safety measures, while effective, are limited in their ability to address the dynamic and multifaceted nature of hazards on the road. Factors such as human error, changing road conditions, and the emergence of new traffic patterns still pose significant risks. These challenges require a comprehensive analysis of opportunities to increase the effectiveness of active car safety. To address these challenges, novel technologies must be explored, industry collaboration must be encouraged, and adaptable standards must be established to integrate and enhance active safety features in vehicles. Thus, itis essential to identify and capitalize on opportunities for progress in active vehicle safety to reduce traffic crashes and promote safer transportation systems Goal. The overarching goal is to significantly improve the effectiveness and breadth of active safety measures for vehicles. This includes: enhanced protection, proactive risk reduction, technology integration, behavioral adaptation, and regulatory strengthening. Achieving these goals will require a multidisciplinary approach that combines technological innovation, behavioral science, regulatory adaptation, and industry collaboration to create a comprehensive and effective active vehicle safety ecosystem. Methodology. Analytical research methods are used, Researching and developing cutting-edge technologies. Originality. A detailed analysis was carried out and the principles of operation of systems and mechanisms included in active safety systems were presented. This analysis will allow to determine the advantages and disadvantages that should be paid attention to when studying these systems. Practical value. Enhanced active car safety offers a variety of benefits and has substantial value. Reduced accidents and fatalities: Reduced accidents and fatalities, advanced safety measures can significantly reduce the frequency and severity of accidents, leading to fewer injuries and fatalities on the road. Improved traffic flow, proactive safety systems reduce potential hazards and contribute to smoother traffic flow and less congestion caused by accidents. Technological innovation, advances in active safety can contribute to broader technological innovation and influence advances in areas other than automotive safety.

The article presents the results of a study performed and substantiated based on the principles of a new method of diagnostics of technical conditions of a hybrid powertrain regardless of the structural diagram and design features of a hybrid vehicle. The presented new technology of the diagnostics of hybrid powertrains allows an objective complex assessment of their technical condition by diagnostic parameters in contrast to existing diagnostic methods. In the proposed method, a mechanism for the general standardization of diagnostic parameters has been developed as well as for determining the numerical values of the parameters of the powertrain. The control subset was used to control the learning error. As a result of debugging the system, the scatter of experimental and calculated points has decreased, which confirms the quality of debugging the tested fuzzy model. As a result of training the artificial neural network, the standard deviation of the error in the control sample was 0.012·Pk. A symmetry method of diagnostics of the technical state of a hybrid propulsion system was developed based on the concept of a neural network together with a neuro-fuzzy control with an adaptive criteria based on the method of training a neural network with reinforcement. The components of the vector functional include the criteria for control accuracy, the use of traction battery energy, and the degree of toxicity of exhaust gases. It is proposed to use the principle of symmetry of the guaranteed result and the linear inversion of the vector criterion into a supercriterion to determine the technical state of a hybrid powertrain on a set of Pareto-optimal controls under unequal conditions of optimality.

“…Among others, for economic and rural development reasons, there is a growing interest in plant-derived fuels (biodiesel) [18][19][20] and LPG or CNG gas fuels [9; 10; 15; 21; 22]. The automotive industry is currently undergoing a huge transformation related to the development of new propulsion systems (hybrid and electric), while improving internal combustion engines [23][24][25][26][27][28][29]. From a local point of view, the operation of electric vehicles can be considered environmentally friendly, since the operation itself does not produce GHG [26].…”

The automotive sector is characterized by a high energy demand related to the use of fuels and maintenance of vehicles in technical readiness. Currently, more and more often solutions are sought that will save energy and cause less losses in the so-called wasted energy. Most of the energy, about 60%, generated from internal combustion engines is dissipated despite the constant efforts of engine manufacturers to improve their economic and ecological properties. In addition, energy is generated in road vehicles from other components, e.g., the suspension system. As a result, systems are being sought to recover some of this energy to power certain sensors and vehicle systems. This study presents energy recovery systems in road vehicles. Based on a literature study of the presented research of various research centres, it was noticed that there is a huge potential in the recovery of energy lost in the vehicle suspension systems. Research shows that it is possible to obtain a regenerative power value of several hundred watts, which depends on the type of vehicle and the road type on which the vehicle is traveling. An area that has been little explored, but also has energy potential, is the recovery of energy from the internal combustion engine suspension system in the engine compartment. This article presents technological solutions for the energy harvesting from the vehicle suspension system and preliminary studies of the potential energy recovery from the suspension of the 4-cylinder in-line diesel engine in an off-road vehicle. It is also important that energy recovery systems have application potential in traditional vehicles powered by internal combustion engines, as well as modern vehicles with hybrid or electric drive.
