Abstract - In today’s world vehicle accident is a
major problem. To avoid this we have developed an automatic impact reducing system in our project. The system is based on intelligent electronically control system known as “Automatic pneumatic-bumper system”. Automatic pneumatic bumper system uses infrared sensor (IR), which is used to sense the vehicle coming is front of our vehicle which is responsible for an accident. As soon as any object or vehicle is sensed by the sensor the sensor sends feedback signal to engine through the relay control to activate the Solenoid Valve which allows the flow of compressed air to the cylinder. During the working of Automatic Pneumatic Bumper system simultaneously the driver also try to stop the vehicle by applying brake pedal which somewhat slows down the engine. The compressed gas flowing through the solenoid valve will activate the cylinder which in turn activates the Bumper. This system provides pre-crash safety to the vehicle. As well as it improves the response time of vehicle braking to keep safe distance between the vehicles. By using this system we can obtain control over the speed of vehicle in short distance Key Words: Automatic Pneumatic Bumper System, IR Receiver, IR Transmitter, Electromechanical System, Solenoid Valve
1. INTRODUCTION India is the developing country. India is a densely populated country with the vehicle usage being really diverse. While the available resources which are used to run the vehicles like road quality & new technologies in vehicles are being developed to avoid accidents. The number of people expired during vehicle accidents is very large as compared to the other causes of death. Though there are different causes for accidents but proper technology of braking system and technology to reduce the damage during accident should be developed. Hence there is need of Impact Reduction system to prevent the accidents and to reduce the damage to vehicle and also the driver. To achieve this goal, we design this Automatic Pneumatic Bumper system. Our main aim is to design & develop automatic control system based on intelligent © 2017, IRJET

2. OBJECTIVES The future of any industry is more than just developing new technology. It is integrating the approach towards achieving safety. Impact Reducing System approach represents considerable shift from the traditional approach to safety, by considering safety in terms of, Firstly avoiding the possibility of accidents, and secondly, protecting occupants when a crash is unavoidable, we can prevent more accidents, save more lives, decrease material damage to vehicles and reduce medical costs. Following are the main objectives of Impact Reduction System with Pneumatic Bumpers: - To ensure the braking of vehicle in time. - To increase the crashing distance during accident. - To increase the safety during pre-crash. - To increase external safety to vehicle body. - To decrease the level of passenger injury by use of external vehicle safety device. - To reduce the requirement of internal safety devices like air bags.
3. CURRENT TRENDS In conventional vehicles there are different mechanism operated for braking system like hydraulic, pneumatic, or mechanical system. But in all these braking mechanisms the input signal is to be given directly from the driver by applying the brake pedal. Thus, braking of vehicles is totally manual operated. So, if the driver fails to see the obstacle in front of his driving vehicle or fails to apply proper braking force on the brake pedal, he may lose the control of his vehicle, leading to accident. Also the driver may not able to pay complete attention when driving at night. So there are many chances of accidents. Urgent application of brakes may also result in imbalance by skidding of the tyres of the vehicle. So, There are no arrangements to prevent or minimize the damage on the vehicle or the passengers.
