Abstract: A wheel is provided with a wheel rim in a single piece that visually corresponds to two ordinary rims joined at their flanges, as well as a wheel rim that integrates this wheel. The wheel, particularly designed for use on vehicles, includes a substantially cylindrical wheel rim and a substantially circular wheel disc associated to each other, the rim having at least two substantially circular and concentric regions and each of the circular regions configuring a groove for positioning a tire. The rim further includes a substantially annular intermediate region provided with at least one radial through bore for ventilation.

Abstract: An obstacle avoidance and vehicle stability system as provided that includes a plurality of wheels, each driven by an independent electric motor. Each of the electric motors provides rotational drive to its respective wheel. The electric motors may also provide braking through a retarding force. A controller is electrically connected to the electric motors. A plurality of vehicle sensors are electrically connected to the controller for detecting vehicle information indicative of vehicle stability. The controller receives information from the vehicle sensors and controls the electric motors and braking device to maintain vehicle stability, for example, during a hard braking maneuver to avoid a collision with an obstacle. The controller commands the appropriate electric motor and/or braking device to accelerate and/or decelerate the appropriate wheel to maintain control of the vehicle.
