Smart eye using Ultrasonic sensor in Electrical vehicles for Differently Able.

Abstract

In this competitive world, electrical vehicles play a vital role. The cost of fuel is rising day by day. In order to meet this issue we need a vehicle that can overcome these problems. Physically challenged people prefer electric vehicles which are more convenient and reliable for them to travel. Controlling the speed in electric vehicles has been a major drawback, which needs to be rectified. The proposed system uses ultra-sonic sensors and controls the speed of the vehicle automatically. The ultrasonic sensors measure the distance of the obstacle and according to the corresponding distance the speed of the vehicle is regulated and reduced gradually. All these processes are carried out by automatic acceleration and deceleration without the guidance of the person driving the vehicle. The process of acceleration and deceleration is more important for controlling the speed of the electric vehicle. The speed is controlled proportional to the distance of the obstacle from the vehicle. Thus it can safely decelerate the speed and turn away from the obstacles. This system ensures safety while driving for the physically challenged person. In addition to the features of ultrasonic sensor, an infrared sensor is also used to avoid collision with obstacles. The variations in the pulse width with respect to changes in the speed is inferred using simulation of Proteus software. Keywords: ultra-sonic sensor, infrared sensor, smart eye.
