The article describes a parametric method of controlling the speed (due to a wide-range stepless change in the gear ratio of the transmission) and substantiates the choice of electric motor and internal combustion engine of hybrid cars. Based on this approach, a typical functional diagram of the drive structure and a two-stage technique for its automated conceptual design using common tools for computing (MS Excel) and modeling (MatLab/Simulink) are proposed. The paper shows an example application of this approach to determine the energy and kinematic parameters of a hybrid car drive on “Granta” chassis (stage 1 of the methodology) and the calculation of operational indicators and characteristics of the concept on the drive simulation model (stage 2 of the methodology) in four characteristic modes. Among them: acceleration-braking—to assess the dynamics of the machine; driving “on the highway” with various constant speeds—to develop recommendations for optimal driving; runs in the “urban” driving cycle, taking into account “traffic jams”—to assess fuel consumption and energy of the traction battery in the main mode of machine operation; the system operation in the “parking” self-charging mode of the traction battery—to assess the autonomy of the developed hybrid car. The developed computer tools of the proposed methodology allow one to make informed decisions even at the stage of conceptual design of hybrid cars very quickly.
