ADAPTIVE SPEED CONTROL AND COLLISION MANAGEMENT IN AUTOMOBILES USING ABS

Electronics and Communication Engineering

Rear end crash is the most common type of road accident. The existence of several technologies to prevent rear end collisions in automobiles work only in low speed. Accidents that occur at low speed doesn’t cause much damage. The proposed technique can prevent accidents at all speed and can be applicable to all kinds of automobiles. The design vehicle is to be equipped with RADAR to sense the distance of preceding vehicle and the speed at which it moves. It is also to be equipped with Anti-Lock Braking System that engages brake to slow down a vehicle, prone to collision until the relative speed between those vehicle and preceding vehicle becomes zero. The Time-to Collision is evaluated and is ensured to be lesser than the braking time to make relative speed to zero. Once the relative speed is made to zero before collision occurs, then the succeeding vehicle will move at a speed equal to speed of preceding vehicle maintaining a constant distance which is equal to stopping distance of vehicle at that speed. The ABS which is now available in all vehicles not only performs effective braking but also maintains stability during the braking process thus preventing collisions at any speed and ensures safety commutation.
