Abstract
An electronic control device for an electric skateboard that obviates the need for remote control is described. The device includes one or more hub motor integrated into a wheel hub or coupled to an axle of the electric skateboard and electric control unit that detects speed or acceleration of the hub motor and adaptively controls speed or torque of the hub motor based on feedback from rider's manual operation of the skateboard.

An electronic control device for an electric skateboard that obviates the need for remote control, the device comprising:
- one or more hub motor integrated into a wheel hub or coupled to an axle of the electric skateboard;
- and
- electric control unit that detects speed or acceleration of the hub motor and adaptively controls speed or torque of the hub motor based on feedback from rider's manual operation of the skateboard,
- wherein the electronic control device is configured with an algorithm that calculates skateboard rider's manual propelling force, weight, or specified speed and an algorithm that compensates the manual propelling force by driving the hub motor to output a resistant electric torque to safely limit acceleration rate of the skateboard at startup.
A method of adaptive control of an electric skateboard without use of a separate controller, the method comprising:
- providing an electronic control device comprising an electric control unit and a power battery, wherein the electric control unit is coupled of a hub motor installed on the electric skateboard, wherein the electronic control device is configured with an algorithm that calculates one or more parameters of the electric skateboard and provides a compensation input to the hub motor,
- wherein the electronic control device manages a damping factor that affects rider's perceived resistance coefficient of a surface.
