Detail:
The project aims at developing mathematical tools to model and simulate scenarios allowing to optimize the performances of diesel-electric hybrid powertrains. In a hybrid vehicle the driving power can be provided by the internal combustion engine or by the motor generator or by a combination of the two. This versatility has to be combined with choices for various degrees of freedom, such as the gear or the vehicle speed, under given on-road and traffic conditions. Furthermore, a new final condition comes in play: the electric stor-age device, namely the battery, which has a limited capacity and needs to remain sufficiently charged. Because of the complexity of the driving mechanism and therefore of its coordination, the system cannot be entirely controlled by the driver in a manual form. At least part of the control effort should be overtaken by automatic algorithms, running on a control unit, mounted in the vehicle. Since the performance of a diesel electric hybrid powertrain heavily relies on the overall management of energy flows and on the control of the powertrain components, the mathematical areas of “Optimal Control” and “Optimization” appear as indispensable tools, not just for design and performance evaluation, but also to derive real time strategies, to be implemented in the control units. The purpose of the study is to evaluate the capabilities and performance of new optimization techniques that can be applied to the energy management of hybrid powertrains.
