In this article, the importance of the interaction between fuel quality and the technical condition of the vehicle is examined to determine its dynamic characteristics and road safety. The research is based on the analysis of the impact of these factors on the vehicle during operation and maneuver execution, especially during overtaking maneuvers where having sufficient engine power reserve to achieve the required level of acceleration is crucial. It is noted that understanding the reasons for changes in dynamic properties is critical, as a reduction in the engine power reserve of the vehicle can complicate the safe execution of overtaking maneuvers. The main focus of the work is placed on the necessity of considering these changes in the vehicle's mobility control systems. The article also includes an analysis of recent research in the field of the interaction between fuel and the technical condition of the vehicle. Research in this area is aimed at understanding the interaction between fuel parameters and the technical characteristics of vehicles to make transportation more efficient, extend the service life of vehicles, and address environmental challenges. The article concludes with findings that emphasize the effectiveness of the developed coefficient for considering the technical condition of the vehicle and fuel quality to enhance the accuracy of safety systems and predict the potential acceleration of the vehicle in traffic. The proposed coefficient will make it possible to increase the accuracy of predicting the potential acceleration of the car by the on-board system. Additionally, the possibility of using this coefficient to detect changes in fuel quality and the technical condition of the vehicle is discussed, providing drivers with information through onboard diagnostic systems and measurement complexes to take appropriate actions.
