The Development of an Automatic Break System for a Wheel Chair in Slope Condition

Abstract

          Speed retarding control in a typical wheelchair is normally mechanically controlled by a user. Sometimes, the wheelchair users which usually are disable people could not properly slow down the vehicle speed and may lead to serious injuries. Therefore; the objective of this work is to construct an automatic speed retarding control in a wheelchair   especially in a slope runway. The speed control system will autonomously monitor the slope condition of the runway by a 3D-accelerometer sensor. When the slope condition reaches the setting value, the servo-caliper break will automatically turn on. With Fuzzy logic algorithm, the wheelchair speed will be smoothly reduced for the safety of the users.
