The present disclosure provides a machine and mechanism of an electrically controlled low-unsprung-mass wheel unit for vehicles. The design incorporates independent propulsion/braking, axle control, steering, and suspension (IPASS) of each wheel during vehicle movement. The purpose of the design is for a traction-adaptively-optimization (TAO) control which include but not limited as the following: 1) better road surface gripping and ride quality by lower unsprung mass; 2) safer, quicker, and sharper turning ability—transformative turning; 3) adaptive obstacle avoidance; 4) a list of new, unique, and advanced vehicle motion features. The mechanism comprises at least: an axle adjustment that controls the distance of a 1165 wheel from the vehicle body, which allows for the outward extension of the wheel via a slider. The slider is connected to a linear actuator, which is powered by the first independent electric motor for track width adjustment. A steering system includes a pinion, powered by the second independent motor, rolls against an inner gear at the top of the unit turn in opposing directions. Hiding the motor and gears in the hollow shaft results in an extremely low profile. A propulsion system, powered by the third independent electric motor, controls the wheel's forward and backward motions using a spline, bevel gear reducer, and planetary gear reducer. Each wheel unit also has an independent suspension system located inside the wheel rim. The suspension uses a hydraulic dampening and supporting system and springs to absorb the shock from vertical movement when driving on uneven surfaces.
