Development of an Efficient Thermal Electric Skipping Strategy for the Management of a Series/Parallel Hybrid Powertrain

In recent years, the development of hybrid powertrain allowed to substantially reduce CO2 and pollutant emissions vehicles. The optimal management such power units represents a challenging task since more degrees freedom are available compared conventional pure-thermal engine powertrain. priori knowledge driving mission allows identifying actual control strategy at expense quite relevant computational effort. This is realized by off-line optimization strategies, as Pontryagin minimum principle—PMP—or dynamic programming. On other hand, for an on-vehicle application, unknown, certain performance degradation must be expected, depending on degree simplification burden adopted strategy. work focused simplified strategy, labeled efficient thermal electric skipping strategy—ETESS, which presents similar but with much-reduced based alternative vehicle either or unit (no power-split between units). ETESS tested in “backward-facing” simulator referring segment C car, fitted series-parallel reliability method verified along different cycles, sizing, efficiency components assessed strategies. outcomes put into evidence that gives fuel consumption close PMP advantage drastically reduced time. extended online implementation introducing adaptative factor, resulting well-assessed equivalent minimization preserving
