Abstract

The main objective of this study was to evaluate the potential benefits that can be achieved with application of various electrified components to a 40 tons heavy-duty long-haul truck. A realistic base long-haul truck with its conventional powertrain components is modelled in a simulation environment and on top of that, by adding degree of freedom to the system with electrified components and their controllers, the opportunities of hybridization in terms of fuel economy

improvement are examined over Heavy Heavy-Duty Diesel Truck (HHDDT) and Urban Dynamometer Driving Schedule Heavy-Duty (UDDSHD) cycles. Every hybrid vehicle configuration as well as the base vehicle used in this study were modeled using representative internal combustion engine (ICE), battery pack and electric drive components in AVL CruiseM™. Hybridization of the long-haul truck offers up to 4.9% fuel economy compared to conventional vehicle. In addition, the same powertrain configuration provides an 24.4% reduction in tailpipe NOx emissions and an 22% reduction in urea consumption.
