“…While a hybrid system itself can lead to a fuel saving potential of 6-8% [33,34], an intelligent EMS can add up to 2% fuel saving. Further fuel saving measures such as e-components and a waste heat recovery (WHR) system can add another 3% [35,36] and 4-5% [37,38], respectively. The design of the powertrain and auxiliaries itself is of significance, as well as the control of the powertrain, as documented in [39,40].…”

To fulfil the CO2 emission reduction targets of the European Union (EU), heavy-duty (HD) trucks need to operate 15% more efficiently by 2025 and 30% by 2030. Their electrification is necessary as conventional HD trucks are already optimized for the long-haul application. The resulting hybrid electric vehicle (HEV) truck gains most of the fuel saving potential by the recuperation of potential energy and its consecutive utilization. The key to utilizing the full potential of HEV-HD trucks is to maximize the amount of recuperated energy and ensure its intelligent usage while keeping the operating point of the internal combustion engine as efficient as possible. To achieve this goal, an intelligent energy management strategy (EMS) based on ECMS is developed for a parallel HEV-HD truck which uses predictive discharge of the battery and adaptive operating strategy regarding the height profile and the vehicle mass. The presented EMS can reproduce the global optimal operating strategy over long phases and lead to a fuel saving potential of up to 2% compared with a heuristic strategy. Furthermore, the fuel saving potential is correlated with the investigated boundary conditions to deepen the understanding of the impact of intelligent EMS for HEV-HD trucks.

“…Net FE benefits when fully loaded on a highway cycle have been estimated at between 5.2% and 13% compared to the conventional baseline. Under transient driving conditions of an urban cycle, FE benefits approaching 38% have been predicted [51][52][53]. Compared to the parallel hybrid configuration over long-haul drive cycles, the PSH design exhibits 0.5% to 2% higher FE improvement and 2% to 3% better engine BTE [132,140,141].…”

“…As a result, the additional energy conversion losses combined with limited regenerative brake opportunities lead to limited FE improvements [88,133]. Various studies have shown fuel economy penalties of between 5% and 16% with high loads on highway drive cycles [51,52]. An SH-LHT in urban driving does show significant potential, with up to 18% fuel economy improvements, due to the greater opportunities for regenerative braking and lower average load demand on the engine [133].…”

Mitigating CO2 emissions from long-haul commercial trucking is a major challenge that must be addressed to achieve substantial reductions in greenhouse gas (GHG) emissions from the transportation sector. Extensive recent research and development programs have shown how significant near-term reductions in GHGs from commercial vehicles can be achieved by combining technological advances. This paper reviews progress in technology for engine efficiency improvements, vehicle resistance and drag reductions, and the introduction of hybrid electric powertrains in long-haul trucks. The results of vehicle demonstration projects by major vehicle manufacturers have shown peak brake thermal efficiency of 55% in heavy-duty diesel engines and have demonstrated freight efficiency improvements of 150% relative to a 2009 baseline in North America. These improvements have been achieved by combining multiple incremental improvements in both engine and vehicle technologies. Powertrain electrification through hybridization has been shown to offer some potential reductions in fuel consumption. These potential benefits depend on the vehicle use, the details of the powertrain design, and the duty cycle. To date, most papers have focused on standard drive cycles, leaving a research gap in how hybrid electric powertrains would be designed to minimize fuel consumption over real-world drive cycles, which are essential for a reliable powertrain design. The results of this paper suggest that there is no “one-size-fits-all” solution to reduce the GHGs in long-haul trucking, and a combination of technologies is required to provide an optimum solution for each application.
