A self-propelled, one-wheeled vehicle may include a suspension system configured to provide arcuate, generally vertical motion of a board relative to an axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems may include a shock absorber and a swingarm that couple the wheel assembly to the board.

An intelligent somatic full-balance electric vehicle comprises two wheels (11, 12) of a same size and a motor (4) disposed between the two wheels (11, 12), the two wheels (11, 12) being coaxially connected to the motor (4) through an axle (3); the intelligent somatic full-balance electric vehicle further comprises a control system (10) and a power supply (9); both the control system (10) and the power supply (9) are disposed inside a housing of the vehicle body and located above the wheels, or between the two wheels (11, 12); or one of the control system (10) and the power supply (9) is located between the two wheels (11, 12), and the other is located above the wheels; vertical columns (6) are separately disposed at two ends of the axle (3), and the vertical columns (6) are separately provided with pedals (5) on external sides of the wheels. Because the two coaxial wheels (11, 12) are used, the electric vehicle can implement full balance like a bicycle, and in addition, has unique advantages of a monocycle, namely, having a small size and being easy to carry.

An electric vehicle may include a board having two deck portions each configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. A motor assembly may drive the wheel assembly in response to board orientation and rider presence information. A rider detection mechanism may include one or more strain gauges, and may be configured to detect rider presence and rider weight information. A responsiveness of the motor may be automatically adjusted based on the rider weight information.

An electric vehicle may comprise a board including first and second deck portions each configured to receive a left or right foot of a ride, a wheel assembly disposed between the deck portions and including a ground-contacting element, a motor assembly mounted to the board and configured to rotate the ground-contacting element around an axle to propel the electric vehicle, at least one sensor configured to measure orientation information of the board, and a motor controller configured to receive orientation information measured by the sensor and to cause the motor assembly to propel the electric vehicle based on the orientation information. The electric vehicle may include exactly one ground-contacting element, and the motor may be a hub motor.

The yoke module is including wherein an elongated USB power cable, one or more yoke module sections accommodating access for the USB power cable and wire connectors to be threaded through one or more slotted openings and to exit out the top yoke module section, a first connection method to connect with the drive motor's lead cable harness directly to the USB power cable, a method to conceal and protect the drive motor's lead cable harness and the USB power cable by means of a coupling enclosure and yoke sleeve enclosure achieved through the yoke module's fabrication process. The yoke module also comprises a method for USB power cable to provide electricity power to drive a motorized wheel. The yoke module system comprises a second connection method for the yoke module to plug into auxiliary components including; a battery, a computer control system, and sensors for motion stability.

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 power control apparatus 10 to supply power, which can be packet transmitted/received, having predetermined identification information in a header part, to a plurality power consumption apparatuses 70 from outside includes (a) an identification information separation apparatus 20 for receiving the identification information and separating it, (b) a power reception propriety determination apparatus 30 for determining whether to receive the power based on the separated identification information, and (c) a power supply control apparatus 40 for controlling the power supply to the power consumption apparatus 70 connected to a power control apparatus based on the separated identification information.

An electric vehicle may comprise a board including deck portions each configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. A motor assembly may be mounted to the board and configured to propel the electric vehicle using the wheel assembly. At least one orientation sensor may be configured to measure orientation information of the board, and at least one pressure-sensing transducer may be configured to determine rider presence information. A motor controller may be configured to receive the orientation information and the rider presence information, and to cause the motor assembly to propel the electric vehicle based on the orientation and presence information.
