Predictive online control for hybrids: global optimality, robustness and realtime capability
In this paper an approach for the real time optimal
control of vehicles with more than one source for providing
traction power (e.g. HEVs) is presented. After a short
classification of existing approaches and their respective
characteristics the new modular concept as a combination of two
algorithms is introduced. For the basic online management an
equivalent consumption minimization strategy (ECMS) is
implemented. The adaption towards changing driving conditions
is realized by an independent calculation and adjustment of the
main decision criterion of the ECMS towards the predicted
operational profile using a calculation time optimized dynamic
programming approach.
