“…The choice of the most efficient mode of operation of the MTA is a rather difficult task (figure 1), the quality of the solution of which is affected by the ability to objectively and accurately determine the current parameters of the unit, to adequately assess the potential for improving the efficiency of the operation being performed, and to take the necessary control actions. To solve this problem, a concept was proposed [11] for the development of a personal electronic assistant for a machine operator, which, based on instrumental control of a number of current parameters of the operation of a machine-tractor unit, makes the necessary calculations and analysis and, in the future, offers solutions to improve the efficiency of the current operation in current conditions (figure 2). The proposed concept made it possible to facilitate the solution of a number of problems.…”
