PURPOSE: A method for driving a force-assisted electric wheelchair is provided to easily apply the method to an existing manual wheelchair or electric wheelchair, and to provide sensors of which the manufacturing costs are lower than the costs of the existing sensors. CONSTITUTION: A method for driving a force-assisted electric wheelchair includes: a step of measuring a force on a hand rim applied by a user using FSR(Force Sensing Registor) sensors(34R,34L); a step of receiving and gathering information measured by the FSR sensors; a step of determining a linear acceleration and an angular acceleration of the center of a wheelchair body by applying a fuzzy algorithm to the information measured by the FSR sensors; a step of calculating and outputting the rotational velocities of motors(50R,50L) driving wheels through the linear acceleration and the angular acceleration; and a step of outputting a motor control signal for driving the motors based on the rotational velocities, and driving the motors.
