The present invention is an electric mobility vehicle such as a powered knee walker, scooter, bicycle and a multi-passenger vehicle comprising a unique steering column assembly capable of being manually steered also autonomously steered by means of steering actuators. The vehicle user can select a manual drive mode option to operate the vehicle physically or the user can select an autonomous drive mode each mode allows the vehicle to operate more efficiently both indoors and outdoors. The vehicle is configured with a platform for standing, sitting and leaning, and the framework is configured with a front and rear drive system, the front drive system incorporates the steering column and one or more steering actuator which control front and rear propulsion systems. The propulsion includes; a DC powered truck module, a fork module, or a cantilever module, and each respectively comprise a drive motor, brake, sensor and accelerometers for self-balancing control. The steering column controlling system is the main driving force of the vehicle and utilizes wireless interface communication linked to short range proximity sensors including LIDAR or laser sensor unit, cameras, and handlebar throttles comprising grip force sensor to control speed and braking, and other vehicle devices. The steering column and framework contain an array of USB power cabling interconnecting electrical components to an IO communication network and to an electrical control system and battery bank.

In an inverted pendulum vehicle, the fore and aft dimension of the vehicle in a forwardly tilted, parked position is minimized. A pivot center line of a base end of a tail wheel arm is located inside a circle centered around a center of a tail wheel and having a radius equal to a distance between the center of the tail wheel and the rotational center line of the drive disks, and with respect to a hypothetical tail wheel arm, a first line is a line extending along the hypothetical tail wheel arm when the vehicle is in the upright position, and a second line is a line extending along the hypothetical tail wheel arm when the vehicle is in the forwardly tilted, park position, the pivot center line being located on or above a bisector of an angle formed by the first line and the second line.

A usage detection system for a self-balancing powered unicycle is disclosed. The usage detection system is adapted to detect an indication of intended usage from a user and to provide an indication of intended usage. The indication of intended usage comprises manipulation of the overall unicycle device resulting from preparatory action taken by the user prior to the onset of the intended usage. Operation of the powered unicycle may thus be controlled based on an indication of intended usage from the usage detection system.

The present invention discloses a self-balancing scooter, including a scooter body. The scooter body includes: an upper shell, a middle shell, a lower shell, pedals and bottom plates. The upper shell includes a first upper shell and a second upper shell. The middle shell includes a first middle shell and a second middle shell.
