A hybrid-propulsion powertrain with planetary gear set: simulation results and a design approach

A power-split hybrid powertrain adopting a planetary gear set is proposed in this work as alternative to the traditional hybrid-propulsion schemes. The main advantages of this drivetrain are: · Sluggish dynamic behaviour of the internal combustion engine, like in series powertrains; · Traction torque provided directly by the Internal Combustion Engine (ICE) and by the electrical drive at the same time, like in parallel powertrains; · 2 or 4-wheels-drive layout; · Pure electric operation when driving into restricted zones. The Simulinkâ model which allows ADVISORã to generate energy flows and emissions of the vehicle is presented. Moreover, the paper explains the control strategy and proposes a design approach of a sports-car adopting this powertrain.
