HANDFREE DRIVING FOR AUTOMOBILES

[attachment=16402]

INTRODUCTION

All of us would like to drive our car with a mobile held in one hand, talking to the other person. But we should be careful; we don’t know when the car just before us applies the break and everything is gone. A serious problem encountered in most of the cities, National Highways, where any mistake means no ‘turning back’! There comes the tomorrows technology; Hand free driven car. Utilizing the modern technological approach in Robotics.[1]


What is the need for safety precaution?

All around the world almost 45% of the accidents occur by mistakes of the driver. In some cases the driver is engaged in some other affair than driving. In USA the highways are so crowded that in some situations mistake on the part of one person on the road can lead to serious accidents. Most of these accidents are fatal. One such accident took place in the year 1997, on a foggy morning the on a heavily traffic highway a series of collisions took place in which 5 lost their life and more than 40 injured.


Automotive Collision Avoidance System
It is the Automotive Collision Avoidance System (ACAS). The ACAS/FOT Program has assembled a highly focused technical activity with the goal of developing a comprehensive FCW system that is seamlessly integrated into the vehicle infrastructure.. The FCW system incorporates the combined ACC & rear-ends CW functionality


Forward Collision Warning system
It is the Forward Collision Warning system. It was one of the earlier programs done by the DDE systems. It included the forward looking radar sensing system. It is high range forward looking radar. Forewarn Smart Cruise Control with Headway Alert uses a mechanically-scanning, 76 GHz, long range radar sensor to detect objects in the vehicle’s path upto 150 meters or 402 feet ahead.
