Abstract
This article presents a cost-based optimization strategy that
explicitly deals with the requirements for fuel consumption and
emissions. Based on the Integrated Powertrain Control (IPC) approach,
the overall powertrain performance is optimized by integrated
energy and emission management. The potential of this
strategy is demonstrated for a parallel hybrid diesel truck with a
Selective Catalytic Reduction (SCR) de-NOx system. New results
are presented for a challenging city cycle; although the average
power demand is low, IPC is able to keep the SCR catalyst temperature
relatively high. With this IPC approach, the CO2-NOx
trade-off is optimized in a systematic way. It is demonstrated that
CO2 emissions and related operating costs are reduced by 3.5%
or 24.9% NOx emission reduction is achieved, depending on the
applied IPC calibration.
