FALL-RESISTANT METHOD OF INTELLIGENT ROLLATOR, INTELLIGENT ROLLATOR AND CONTROLLER THEREOF

Disclosed is a fall-resistant control method for an intelligent rollator, an intelligent rollator and a controller. The intelligent rollator has a vehicle body, front wheels and/or rear wheels configured at the bottom of the vehicle body and driven by a motor. The fall-resistant control method includes: recording the current position of the motor as the initial position when the moving speed of the intelligent rollator exceeds a first threshold and the acceleration of the intelligent rollator exceeds a second threshold; determining a first braking torque according to the position change of the motor relative to the initial position, wherein the greater the position change, the greater the first braking torque; determining a second braking torque according to the moving speed and/or acceleration of the intelligent rollator, wherein the greater the moving speed and/or the acceleration, the greater the second braking torque; determining the fall-resistant braking torque according to the first braking torque and the second braking torque.
