CONTROL SYSTEM FOR WHEELCHAIR USING PALATAL PLATE

摘要

PROBLEM TO BE SOLVED: To provide a control system with which a wheelchair may be safely controlled because it is possible to surely judge which pressure sensor is operated by a tongue. SOLUTION: Four pressure sensors are placed in a wireless type palatal plate, a pressure sensor exhibiting the greatest pressure value is identified as a pressure sensor operated at this time point based on the pressure signal data from each pressure sensor inputted through transmitting and receiving circuits (step S27). On a step S37, going straight or turning to the right or to the left of the wheelchair is judged, and in steps S39 and S41 or steps S43 and S45, a PWM value corresponding to pressure value data at the time point is outputted and the wheelchair is driven.
