Control and Optimization of Hybrid-electric Vehicle Powertrains

Dear colleagues,

ICE-based hybrid propulsion systems still appear to be one of the most promising technologies available to face the transition towards the sustainability of the mobility sector, especially in extra-urban environments and for heavy-duty applications. Many off-road propulsion applications could benefit substantially from the definition of low-environmental-impact and low-energy-consumption hybrid propulsion systems. From this point of view, the hybridization of electric propulsion systems with lower energy vectors (e.g., CNG, LMG, LPG, hydrogen, and biofuels) could introduce further benefits both on a tank-to-wheels (TTW) and on a well-to-wheels (WTW) basis.

Hybridized propulsion systems, however, introduce one or more freedom degrees to be optimized. Optimizing rules and algorithms should be differently designed considering the functional connections between the different available fuel sources (e.g., series, split, parallel hybrids), the sizing and characteristics of conventional or innovative on-board energy storage systems (ESSs), as well as the various possible applications and the foreseen use cycles of the vehicles. All this considered, a strong effort of the scientific community is still needed in this sector. This Special Issue therefore invites original papers on all aspects connected to the control and optimization of hybrid-electric vehicle powertrains. In more detail, expected contributions for the Special Issue could for example regard (but are not limited to):

• Control and optimization algorithms for hybrid-electric vehicle powertrains;
• Modeling and prediction of powertrain energetic and environmental behavior;
• Optimal powertrain design;
• Conventional and innovative energy storage systems (ESSs): their modeling, management, and control;
• Expected well-to-wheel (WTW) and tank-to-wheel (TTW) vehicle performances;
• Regenerative braking strategies and control.
