1. 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.
