Abstract
This paper investigates the effect of the powertrain efficiency map on energy optimal speed trajectories, especially stop-to-stop trajectories. A variety of different efficiency maps are explored and the energy optimization process is carried out. It is shown that while the efficiency maps can have a significant impact on the overall transportation energy, they have little impact on the shape of the optimal speed profiles. A number of very different efficiency maps and their effects on speed trajectories are illustrated. Also, the impact that vehicle and segment parameters as well as average speeds have on the savings are investigated. This paper also presents the impact of transient penalty on the shape of the energy optimal trajectories and associated savings. It is observed that, by adding an additional transient penalty to the energy balance, the shape of trajectories changes and energy savings decrease.
