ACCIDENT AVOIDING BUMPER SYSTEM

The aim is to design and develop a control system based intelligent electronically controlled automotive bumper activation and automatic braking system called AUTOMATIC ACCIDENT AVOIDING SYSTEM (FOR BUMPER CAR). This project consists of Control Unit, Pneumatic bumper system and pneumatic braking system. The Ultrasonic sensor senses the obstacle. There is any obstacle closer to the vehicle the control signal is given to the bumper activation system and also braking system simultaneously. The bumper and braking system are used to protect the person and vehicle. Some of the automotive manufacturers already use shock absorption system that consist passive damper located between the bumper and the vehicle chassis. However, by using this system most of the force will be dissipate by transmitting all the impact energy through the compression of the damper and the remaining force will be transferred to the vehicle chassis. This system normally has very high static damping coefficient and cannot dissipate higher speed collision force. In this project, dampers were used to provide dynamic damping coefficient and reduced the crash impact and lowering the transmission of the remaining force to the vehicle body. The present work is an attempt to develop a concept to make a shock proof accident avoiding system which can meet out the requirement of safe journey. The objective of bringing down the rate of accidents which are increasing day by day is almost achieved in present work within the limitation of work as mentioned.
