Abstract
Energy management in modern vehicles typically relates to optimizing the
powerflow in the (hybrid) powertrain, whereas emission management is associated with the combustion engine and its aftertreatment system. To achieve maximum performance in both fuel economy and hazardous emissions, the concept of Integrated Powertrain Control (IPC) is presented.
This paper presents an overview of TNOs IPC roadmap. It is shown how system integration takes a dominant role in the near future and how complexity of the powertrain is handled in a structured way. The potential benefit of IPC is emonstrated for a commercial hybrid delivery truck case study. Based on simulations with a validated powertrain model, analysis is carried out considering the trade-off between energy management and emission management. It is demonstrated that the CO2 emissions and related operational costs allow
for a reduction of 3.5%, whereas NOx emissions can be reduced up to 27%. The added value of IPC is that it targets the NOx emissions exactly at the boundary set by emission legislation whereas the remaining freedom is used to achieve lowest operational costs.
