Fully-automatic wheelchair and control method

The invention discloses a fully-automatic wheelchair and a control method. A detection system is connected with a control system. Steering, acceleration, deceleration and balance of the wheelchair are controlled by the control system through an adjusting system. The detection system comprises an ultrasonic sensor and a tilt angle sensor. The control system controls steering, acceleration and deceleration of the wheelchair according to received road condition information fed back by the ultrasonic sensor, and controls a pushing rod motor to work according to received information of the tilt angle sensor so as to enable a seat of the wheelchair to rotate around a wheelchair support, so that the seat of the wheelchair is always perpendicular to the horizontal plane. According to the fully-automatic wheelchair and the control method, due to the fact that the detection system composed of the tilt angle sensor and the ultrasonic sensor is arranged on the wheelchair, the road condition is detected in the moving process of the wheelchair, and the wheelchair is made to avoid obstacles in time; the seat of the wheelchair is made to rotate around the wheelchair support, so that the seat of the wheelchair is always perpendicular to the horizontal plane, the discomfort caused by center-of-gravity shifting of a rider during slope climbing is eliminated, and stability of slope climbing is improved.
