Estimation of the efficiency of functioning of the driver-car-road-environment system by energy indicators

The driver-car-road-environment (DCRE) system is a large and complex system, the efficiency of which is closely related to significant energy costs. Estimation of energy costs during the operation of the DCRE system and finding reserves for increasing the efficiency of the system remains an important task in the present time. The functioning of the DCRE system is characterized by a change in the parameters and dynamic properties of its constituent elements in a wide range and sometimes in an unpredictable manner. In practice, a partial study of the influence of individual factors or their combinations on the effectiveness of the DCRE system seems to be a rather difficult task. This necessitates a comprehensive energy assessment of the functioning effectiveness of the DCRE system. The studies were carried out in order to assess the efficiency of the DCRE system and develop proposals for identifying reserves to reduce energy and material and technical costs when solving issues related to the efficiency of the transport process in mountainous conditions. Until now, when assessing the effectiveness of the functioning of the DCRE system according to the energy indicator, methods based on assessing the effectiveness of its individual elements have been used. It is advisable to use a systematic approach to solving such problems. The obtained results of the effectiveness of the functioning of the DCRE system indicate the low efficiency of the system in terms of energy indicators, as well as the existing sufficiently wide possibilities and ways to increase its efficiency. The proposed mathematical models for assessing the energy efficiency of the functioning of the DCRE system in relative units, as well as in quantitative terms (in terms of linear fuel consumption) are sufficiently adequate for practical purposes. The article proposes a mathematical model for a comprehensive energy assessment of the efficiency of the DCRE system by linear fuel consumption.The research results can be introduced into production when calculating the efficiency of the transport process.
