Abstract :
A dual-motor-driven rear-wheel four-wheel electrical powered wheelchair is introduced, whose seat can move to facilitate mobility of people on and off. The system is composed of two MCUs, the main control fragment is completed by the MCU I. MCU I is used to detect rocker movement, MCU II is used to detect speed and display the current state of operation through the LCD chip 12864. In the process of acceleration and deceleration, an S-curve velocity control algorithm is used to ensure the human riding comfort. The experiment shows that the system basic characteristic is satisfied.
