Recentemente, i trasporti sono stati una delle categorie più attenzionate per quanto riguarda le preoccupazioni globali sulle tematiche di inquinamento ambientale e sicurezza energetica. L’Europa si sta impegnando a transitare verso una mobilità totalmente sostenibile. L’utilizzo di veicoli elettrici sta diventando le soluzioni maggiormente adottate, tuttavia per agevolare questa trasformazione è importante anche ottenere un miglior risultato in termini di consumi ed inquinamento dai veicoli con motori a combustione interna (ICEVs). Offrire una modalità di valutazione del consumo energetico dei veicoli, per poter identificare potenziali margini di miglioramento, è vitale e necessario. In tal senso, questo lavoro di tesi mira a proporre un’equazione del consumo energetico che si applichi ai cicli di guida WLTP ed offra versatilità rispetto alle diverse tipologie di veicoli a cui viene applicata. A tale scopo, ricerche precedenti hanno proposto l’equazione per il NEDC, stessa metodologia applicata per il nuovo ciclo di guida. L’espressione viene verificata tramite MATLAB e VI Grade CarRealTime, ne viene inoltre proposta anche una versione estesa che include nel calcolo gli effetti di scivolamento longitudinale. Delle equazioni presentate vi è anche data evidenza dell’intero processo d’analisi sottostante, ottenendo basse percentuale di errore ed un alto potenziale di implementazione in stime reali.

Abstract
In recent years, transportation has been one of the centers of attention regarding the global concerns about environmental pollution and energy security. Europe has committed to transforming into a sustainable mobility. The use of electric vehicles is becoming the solution but achieving better fuel consumption for internal combustion engine vehicles (ICEVs) is also important for this transition. Offering a way to estimate the energy consumption of vehicles to identify the potential windows of opportunity to improve it, is vital and necessary. In that sense, this thesis work aims to propose an energy consumption equation that applies for WLTP driving cycles and offers versatility to be applied for different types of cars. For that purpose, previous research has advised the equation for NEDC, and this methodology is used for the new driving cycle. The expression is verified through MATLAB and VI Grade CarRealTime, and an extended version that encompasses the longitudinal slip effects is also proposed. The equations are presented and all the analysis behind is also shown, obtaining low percentages of error and a high potential to be implemented in real estimations.File | Dimensione | Formato | |
