Abstract: The aim of this paper is to present mathematical models of all the propulsion components of mild-hybrid and full-hybrid transmissions that allow the modelling process of fuel and energy consumption in any homologation driving cycle to be performed in detail. The characteristics provided in the article concern: the full load engine torque curve, full load electric motor power curve, combustion engine efficiency characteristic, including dynamic states and warm-up period, electric motor efficiency characteristic, inverter efficiency characteristic, battery characteristics in a wide temperature range and efficiency of the transmission. Moreover, the main principles concerning vehicle resistance and gear ratio selection are provided. The article concerns all the aspects limiting ranges of gear ratios, engine and motor(s) speed as well as their torque and power for the most common designs of hybrid transmissions: mild-hybrid with manual and dual-clutch gearbox, parallel full-hybrid with dual-clutch gearbox and full-hybrid e-CVT: series and series-parallel.
