Dynamic Modeling and Testing of a Novel Drive-by-Wire Pedal-Assisted Electric Ultralight Vehicle

Advances in transportation and mobility constitute a cornerstone of sustainable development. This work presents the SNAP vehicle, a four-wheel, pedal-assisted electric platform designed to bridge the gap between bicycles and conventional automobiles. Particular attention is devoted to the drivetrain architecture and to the adoption of a drive-by-wire system in place of a traditional chain transmission. The study specifically examines the single-motor configuration, in which traction is provided by the rear-right wheel, and includes the instrumentation of a prototype vehicle to assess whether such a layout ensures satisfactory dynamic performance. These investigations directly contribute to two United Nations Sustainable Development Goals: SDG7, which promotes affordable and clean energy, and SDG11, which focuses on creating sustainable cities and communities.
