Abstract
A method of controlling a motorized wheelchair including a seat frame supporting a seat, a back frame to which the seat frame is detachably connected, a first main wheel and a second main wheel respectively installed at both lower ends of the back frame, an inclination detecting sensor which detects an inclination, and a controller which controls the main wheel and the second main wheel, includes receiving an input for a turning operation, calculating an inclination angle of a running ground by the inclination detecting sensor, and determining whether the inclination angle is greater than a reference angle.
