The paper describes a simple simulation tool for determination of vehicle energy consumption under dynamic conditions, suitable for early stages of design and linked to other tools being developed inside Vehicle concepts modeling (VECOM) project framework. The simulation tool is based on ordinary differential equations and a dynamic expandable library of vehicle component features. It describes vehicle dynamics in longitudinal direction and the appropriate efficiencies of engine, transmission and accumulation components (if used). All required data may be obtained by targeted simulations using multi-dimensional methods or by experiments. The simplified algorithms finding the best usage of powertrain chain efficiency in dependence on required pre-defined operation conditions (real driving record or a driving test cycle) were established.
