A mobility assistance device and a driving method thereof are provided. The mobility assistance device includes at least one bracket and a driving device which drives the at least one bracket. The driving device includes a brushless direct current (DC) motor, a rotor angle sensor, and a sensing driver. The rotor angle sensor senses the angle of the brushless DC motor. The sensing driver uses a corresponding algorithm to estimate a corresponding angle corresponding to an angle velocity switching of the brushless DC motor. The corresponding angle is used as an angle of the brushless DC motor. The sensing driver drives the brushless DC motor according to the corresponding angle, so that the brushless DC motor provides supporting force to the at least one bracket.

Mobility assistance device and driving method therof

A force applying auxiliary device and a control method thereof are provided. The force applying auxiliary device includes a sensor group, a processor, and a force applying driver. The sensor group includes a first sensor disposed on a first side and a second sensor disposed on a second side. The processor collects motion posture data of a user according to the first sensor and the second sensor, and determines whether a motion of the user is abnormal. When determining that the motion of the user is abnormal, the processor selects at least one preset abnormal pattern as a specific abnormal pattern according to the motion posture data, and controls the force applying driver to provide a force by using the specific abnormal pattern. A force difference between first and second forces applied to first and second side feet is adjusted based on a difference in sampling values between the sensors.
