An objective of the present invention is to provide an electric wheelchair and a control method thereof which can minimize a volume when not in use. According to an embodiment of the present invention, the control method of an electric wheelchair comprises: a step wherein a backup command is inputted by an input unit in an electric wheelchair including a seat frame having a seat to allow a user to sit thereon, a back frame having a backrest to support the back of the user and being separably coupled to the seat frame, and a main wheel coupled to the lower end of the back frame; a step of outputting an image photographed by a rear camera installed in the back frame to an output unit; a step wherein a rear protrusion detection sensor installed in the lower surface of the back frame detects a protrusion on the ground; a step of determining whether a protrusion detected by the rear protrusion detection sensor is higher than or equal to a preset reference protrusion; an emergency braking step of operating a brake of the main wheel if the detected protrusion is higher than or equal to the reference protrusion; and a step of outputting a warning for the detected protrusion to the output unit.

    본 발명의 실시예에 따른 전동 휠체어의 제어방법은, 사용자의 착좌를 위한 시트가 구비되는 시트프레임, 사용자의 등을 지지하는 등받이가 구비되며, 상기 시트프레임과 분리 가능하게 결합되는 백프레임 및 상기 백프레임의 하단에 결합되는 메인휠을 포함하는 전동 휠체어에 있어서, 입력부에 의하여 후진 명령이 입력되는 단계; 상기 백프레임에 설치되는 후방 카메라가 촬영한 영상을 출력부에 출력하는 단계; 상기 백프레임의 저면에 설치되는 후방 단차 감지센서가 지면의 단차를 감지하는 단계; 상기 후방 단차 감지센서에 의하여 감지된 단차가 미리 설정된 기준단차 이상인지 판단하는 단계; 상기 감지된 단차가 상기 기준단차 이상인 경우, 메인휠의 브레이크를 작동시키는 긴급 제동 단계; 및 상기 출력부로 상기 감지된 단차에 대한 경고를 출력하는 단계를 포함할 수 있다.
