Abstract: A stabilizer is disclosed for a three-wheel vehicle having a frame extending between a front portion and a rear portion. The front portion of the frame supports a front steering wheel and with the rear portion of the frame supports plural driving wheels. The stabilizer comprises a right and a left stabilizing wheel mounted on a right and a left side of the frame. The right and left stabilizing wheels are positioned above the supporting surface when the three-wheel vehicle moves in a straight direction on a supporting surface. The right and left stabilizing wheels engage the supporting surface when the vehicle is turned in a right and a left direction respectively for stabilizing the three-wheel vehicle while maintaining steering ability. Preferably, the stabilizer includes a right and a left director for directing the right and left stabilizing wheels in a forward direction when the right and left stabilizing wheels are positioned above the supporting surface.

Abstract: An electronic steering assembly is disclosed for a dual motor vehicle having a first and a second motor for driving a first and a second drive wheel. The electronic steering assembly comprises a handlebar rotatably mounted relative to a base. A sensor senses the rotational position of the handlebar relative to the base. A control is interposed between the sensor and the first and second motors for powering the first and second motors in accordance with the rotational position of the handlebars for steering the dual motor vehicle through the rotational movement of the handlebar.

Abstract: A power wheel chair is disclosed having an improved motion control comprising a frame having a seat for transporting an occupant. A right and a left caster wheel are located in proximity to a front frame end. A right and a left drive wheel are located in proximity to a rear frame end.

Abstract: A foldable personal mobility vehicle is disclosed comprising first and second units having first and second wheels being rotatable about first and second axles. A drive unit rotates the second wheel for moving the foldable personal mobility vehicle. A pivot disposed substantially parallel to the first and second axles pivotably connects the first unit to the second unit for folding the personal mobility vehicle. The foldable personal mobility vehicle may include a folding unit for automatically folding the foldable personal mobility vehicle.

Abstract: A vehicle is disclosed having a reduced turning radius comprising a directional wheel assembly for turning the vehicle and a drive wheel assembly for driving the vehicle. The drive wheel assembly has a first and a second drive wheel independently driven by a first and a second motor through a control circuit. A counter-rotation circuit counter-rotates the first and second drive wheels upon a major turning position of the directional wheel assembly to enhance the turning of the vehicle. A reducing circuit reduces the speed of the motors upon a minor turning position of the directional wheel assembly. The vehicle may include a slide mechanism for providing a reduced wheelbase to further reduce the turning radius of the vehicle. One embodiment of the invention includes an improved steering device for controlling the directional wheel assembly.

Abstract: An improved footrest system and an improved electrical switching device are disclosed for a personal mobility vehicle having a rotatable chair. The improved footrest system comprises a first and a second footrest plate pivotably mounted to a first and a second end of the personal mobility vehicle.
