Structural diagram of the "driver-car-environment" system

Abstract

A conceptual scheme of the "driver-car-environment" system is proposed, which uses the provisions of the theory of functional systems and the presentation of the car as a functional system containing three levels: engine, chassis and body. The functioning of the system is characterized by a change in the parameters and dynamic properties of its elements in an unpredictable manner. Information interactions at the tactical level are considered as interactions of multimodal images of the elements of the "driver-car-environment" system, presented in the form of state vectors of these elements. Factors affecting the efficiency of system functioning are considered. A diagram of the functioning of the "driver-car-environment" system has been developed using system objects, which allows evaluating the influence of various factors on system indicators, taking into account the main processes of the system, feedback as process control parameters, and connections with the environment that take place in operating conditions. In particular, the driver's control actions are characterized by actions on the accelerator pedal, clutch pedal, gearbox lever, steering wheel, brake pedal. The "environment" subsystem is characterized by the parameters of the road and atmospheric air. The efficiency of the system is closely related to significant energy consumption. The system has low productivity in terms of energy indicators, but the reserves for increasing its profitability are far from exhausted. Until now, when evaluating the effectiveness of the VANS system according to the energy criterion, methods based on the evaluation of the effectiveness of its individual elements were used. The system approach allows you to evaluate energy and material costs and find reserves for improving the efficiency of the system as a whole.
