Abstract [en]

With upcoming stricter emission legislations and increasing fuel prices reducing fuel consumption, i.e. CO2 emissions, are one of the driving forces behind development in the automobile industry. One solution to reduce fuel consumption is hybridization, giving the vehicle overall higher engine efficiency. In this thesis it has been investigated if it is possible to reduce fuel consumption via hybridization with maintained performance for different hybrid topologies and degree of hybridization. This is investigated by developing models in Matlab/Simulink which are used in the AVL rapid prototyping’s plant model. Results from the simulations shows that there are vehicle layouts that would comply with set demands (fuel consumption and performance) both when using parallel and series topology. The conclusion is that the fuel consumption reductions are large enough to make it interesting with hybridization, however further investigation is needed to determine if the increased costs would make hybridization beneficial.

Abstract [sv]

Stigande bränslepriser och framtida lagkrav har gjort att minskad bränsleförbrukning (CO2-utsläpp) är en av de drivande krafterna i utvecklingen hos dagens bilindustri. Ett sätt att lösa detta är med hjälp av hybridisering, som låter förbränningsmotorn arbeta på bättre effektivitetspunkter. I det här projektet har det undersökts om det är möjligt att reducera bränsleförbrukningen och samtidigt bibehålla fordonets prestanda med hjälp av olika hybridiseringsstrategier och -grader. Undersökningen har utförts genom att modeller har tagits fram i Matlab/simulink och sedan använts med simuleringsverktyget i AVLs rapid prototyping styrsystem. Resultaten från dessa simuleringar visar på att det finns fordon med komponentkombinationer som uppfyller kraven på lägre bränsle förbrukning och prestanda för både parallell- och seriehybrider. Slutsatsen är att bränslebesparingarna är tillräckligt stora för att göra hybridisering intressant, dock behövs vidare undersökningar om huruvida det är ekonomiskt hållbart med hybridisering.
