Abstract: Based on the electric-powered wheelchair kinetic control system developed by the author,this paper proposed treatises on various fault detection schemes of the electrical component and wiring problems,such as joystick displaced,low battery,charging mode,MOSFET fault,brake disconnections,and etc.Specially,this paper proposed the charging mode and brake disconnection fault detection schemes initiatively in domestic,which greatly enforce the safety and reliability of the electric-powered wheerlchair kinetic control system.The fault detection methods have the reference value in application.
