The growing electrification of automotive systems is driving increasing interest toward suspension technologies that enhance ride comfort and road holding, while improving vehicle energy efficiency, enabling active control of vehicle dynamics, and the recovery of energy from road-induced excitations without requiring major changes to existing vehicle architectures. Within the objectives of the ”Spoke 2: Sustainable Road Vehicles” project, devoted to the development of lightweight, energy-efficient, and reconfigurable electric vehicles, the integration of an active suspension system represents a key step toward reducing the environmental, economic, and social impact of road transportation. This thesis investigates the integration of a Rotary Regenerative Shock Absorber (RRSA), into the rear suspension of a low-voltage reconfigurable battery electric vehicle equipped with a conventional twist beam suspension layout.
