SmartCorners: Innovative E-Corner Design of Smart Electric Vehicle

17th NOVEMBER 2025 ACTIVE SUSPENSION DESIGN A complete suspension rethinking and redesign is possible with the adoption of an electromechanical active shock absorber. The damper tube can be removed, and the coil spring is replaced by a torsion bar to ensure the system’s required stiffness. The freedup space is exploited to fit the active shock absorber leverage, optimized to achieve the required damping performances. Also, the endstops are embedded in the actuator design. SKATEBOARD DEMONSTRATOR Between the several project outputs, a demo skateboard vehicle will be assembled and tested in PoliTo to assess and show the benefits of such an innovative vehicle architecture. The skateboard will allow to demonstrate the benefits of combining IWMs with advanced by -wire technologies. PROJECT OVERVIEW The project aims to refine electric vehicle (EV) design and operation through user-centric,adaptable, and energy-efficient smart corner systems (SCS), which incorporates in-wheel motors (IWMs) and advanced vehicle dynamics control technologies. SMART-CORNER DESIGN The smart corner system represents a compact, scalable and modular unit, combining within the corner the powertrain (IWM), the by-wire braking and steering systems, and the vertical dynamic control of the vehicle with an active electromechanical shock absorber. All SCS components are seamlessly integrated into the corner architecture, providing a modular design that can be easily applied to various vehicle chassis. This configuration supports the use of a skateboard chassis while freeing up space for the battery pack, passenger cabin, and luggage compartment .
