The invention discloses a dynamic balance scooter and a speed-limiting control method and system thereof. The speed-limiting control method of the dynamic balance scooter comprises the steps of obtaining the real-time duty ratio of pulse width modulation signals of a motor, comparing the real-time duty ratio with the target duty ratio threshold value of the pulse width modulation signals of the motor in a speed-limiting mechanism, judging whether the real-time duty ratio of the pulse width modulation signals of the motor exceeds the target duty ratio threshold value of the pulse width modulation signals of the motor and carrying out speed-limiting control over the dynamic balance scooter according to the comparison result if yes. Due to the fact that the real-time duty ratio of the pulse width modulation signals of the motor directly reflects the carrying state such as the weight of a driver, the habits of the driver and the road condition, speed-limiting control over the dynamic balance scooter can be achieved by comparing the real-time duty ratio with the duty ratio threshold value.
