The purpose of this thesis is to explore the main motivations that influence the transition to a new generation of Electrical and Electronic (E/E) architectures based on the Software-Defined Vehicle (SDV) paradigm. Today, the E/E architecture can be considered as the nervous system of the vehicle; in fact, the E/E architecture includes both ECUs and the vehicle network that, organized together, realize the vehicle functions. So the E/E architecture represents the element that enables vehicle innovation, from basic control tasks to advanced capabilities such as autonomous driving and over-the-air (OTA) software updates. This work also aims to propose potential solutions for future E/E architectures expected to evolve from traditional distributed systems toward zonal SDV architectures.
