Self-stabilizing skateboard
DCFirst Claim
1. A self-balancing electric vehicle comprising:
- one or more wheels having a common axis of rotation;
a board having a first end and a second end, wherein the board is tiltable about the axis of rotation of the one or more wheels;
an electric hub motor coupled to a power supply and configured to drive the one or more wheels;
a motor controller configured to receive orientation information indicating an orientation of the board and to cause the hub motor to propel the board based on the orientation information; and
a pivotable handle which is transitionable between a stowed configuration, in which a distal end of a grip portion of the handle is disposed adjacent the hub motor, and a deployed configuration, in which the distal end of the grip portion of the handle extends away from the hub motor.

Abstract
A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

23. A self-balancing electric vehicle comprising:
-
a board having a first deck portion and a second deck portion, and an opening between the first and second deck portions, wherein each of the first and second deck portions is configured to support a respective foot of a user oriented perpendicular to a direction of travel; a wheel disposed in the opening between the first and second deck portions, wherein the board is tiltable about an axis of the wheel; a hub motor configured to drive the wheel; a power supply configured to power the hub motor; a motor controller configured to receive orientation information indicating an orientation of the board and to cause the hub motor to propel the board based on the orientation information; a status indicator including a plurality of illuminators viewable through a slot formed in an upper surface of the board; and a handle pivotably attached to an axle mounting block of the vehicle and configured to transition between a stowed configuration in which a distal end of the handle is disposed adjacent a hub portion of the wheel and held in position magnetically, and an extended configuration in which the distal end of the handle extends away from the hub portion of the wheel. - View Dependent Claims (24, 25, 26, 27, 28)
