Intelligent wheelchair based on motor imagery electroencephalogram and head posture and control method

The invention discloses an intelligent wheelchair based on motor imagery electroencephalogram and a head posture and a control method. The intelligent wheelchair comprises an electric wheelchair and additional devices including electroencephalogram acquisition equipment, head posture acquisition equipment, neck myoelectricity acquisition equipment, a head posture estimation module, a virtual cursor control module, a wheelchair man-machine interaction interface module, a fatigue sensing module and an intelligent wheelchair. A control method comprises the following steps: (1) in a motor imagery electroencephalogram control mode, using sensory motion rhythm to control a virtual cursor, and in the head posture interaction control mode, using a head posture to control the virtual cursor; (2) switching the motor imagery electroencephalogram control mode and the head posture interaction control mode according to the fatigue state of the neck muscles of the user; and (3) calculating corresponding rotating speeds of l
