Questa tesi è sviluppata in collaborazione con Aston Martin Lagonda ed Imperial College London. Il suo scopo principale è quello di costruire un modello di veicolo elettrico ibrido ad alte prestazioni per scopi di simulazione e studiare strategie avanzate di gestione dell'energia ottimizzate sia per le performance sportive sia per l’omologazione delle emissioni.
This thesis is developed in partnership with Aston Martin Lagonda and Imperial College London. His main purpose is to build a high-performance hybrid electric vehicle model for simulation purposes and study advanced energy management strategies for both race and homologation performances. At the present time it is expected that the importance of the software will be such that it can optimize the integration between electric and thermal motors and be able to drive the vehicle completely autonomously in all conditions, according to the most important purposes of always increasing performances and at the same time reducing as much as possible the emissions. All these considerations become increasingly important and difficult to combine when it comes to high-performance electric hybrid vehicles, since on the one hand you have to consider the enormous weight of performance that must be extreme and to the continuous search for the record over competitors and on the other hand consumption intended as a focus on environmental impact and fuel economy for the customer. These considerations seem to be at odds with each other, but with an appropriate integration strategy will ensure a new generation of high-end vehicles that are significantly better performing than in the past, passed in all respects. The considerations presented above are most necessary than ever to understand the complex panorama in which car manufacturers currently are. While hybrid vehicles were destined for mass production at the beginning of their production due to the issues just listed, environmental impact, in recent years manufacturers of high-performance supercars and hypercars have also begun to hybrid models on the market. The main reasons for this choice are two: the first is the need to increase the power-to-weight ratio (specific power) as much as possible in order to be able to be lendly and technologically better than the competition (currently it has been vehicles with powers greater than 1000 hp thanks to the introduction of electric propulsion. The second is the need for all carmakers to lower the quotas of C02 total of their fleet to avoid paying fines, if in fact initially this problem was not a priority for such manufacturers now begins to be a goal to be achieved in order not to run into financial problems. It is important to consider in this first phase of analysis how the achievement of the power density share of 200 hp/liter must necessarily pass through the union of a traditional thermal and an electric powertrain. This consideration, however, opens up more complex scenarios when we talk about the total weight of the vehicle, in fact if on the one hand you can achieve the ambitious goal for which it concerns the power density on the other it goes to worsen the appearance related to the weight CO2 emissions and dynamic vehicle performances. The aim of the thesis will therefore be to present the benefits of electrifying a high-performance vehicle both from the point of view of the performance aspects, which characterizes the definition of a sports vehicle itself, as well as in terms of It concerns the environmental aspect related to lower fuel consumption and therefore harmful emissions to the planet.
