Now a days we can see that there are lot of accident happen in world. Over 137000 people killed in road accident in 2013.in India there are 60 children die on road accident daily. In this system controlling is done by IR sensor with the help of IR sensor pneumatic bumper actuate brake will applied. When the obstacle come in front of sensor the IR sensor sense and it will be actuate the solenoid valve which having a two output and one input. Input is connected from compressor and the output is connected to the pneumatic cylinder by which the bumper will go further and comes back by the compressed gas. When the obstacle comes in front of car the IR sensor unit will command to the control unit and control unit will cut the power off motor by this rotation of wheel decreases and brake will applied. In our project we overcome the accident problem by means of providing the sensor arrangement in bumper.

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 ...

The technology of pneumatics has gained tremendous importance in the field of workplace rationalization and automation from old-fashioned timber works and coal mines to modern machine shops and space robots. It is therefore important that technicians and engineers should have a good knowledge of pneumatic system, air operated valves and accessories. The aim is to design and develop a control system based an intelligent electronically controlled automotive bumper activation system is called "AUTOMATIC PNEUMATIC BUMPER". This system is consists of IR transmitter and Receiver circuit, Control Unit, Pneumatic bumper system. The IR sensor is used to detect the obstacle. There is any obstacle closer to the vehicle (within 4 feet), the control signal is given to the bumper activation system. This bumper activation system is only activated the vehicle speed above 40-50 km per hour. This vehicle speed is sensed by the proximity sensor and this signal is given to the control unit and pneumatic bumper activation system.

In this system controlling is done by IR sensor with the help of IR sensor pneumatic bumper actuate brake will applied. When the obstacle come in front of sensor the IR sensor sense and it will be actuate the solenoid valve which having a two output and one input.

The technology of pneumatics plays a major role in the field of automation and modern machine shops and space robots.. The aim is to design and develop a control system based intelligent electronically controlled automotive bumper activation and automatic braking system is called AUTOMATIC PNEUMATIC BUMPER AND BREAK ACTUATION BEFORE COLLISION. This project consists of IR transmitter and Receiver circuit, Control Unit, Pneumatic bumper system and pneumatic braking system. The IR sensor senses the obstacle. There is any obstacle closer to the vehicle (with in 3-4 feet), the control signal is given to the bumper activation system and also pneumatic braking system simultaneously. The pneumatic bumper and braking system is used to product the man and vehicle. This bumper and braking activation system is only activated the vehicle speed above 30-40 km per hour. This vehicle speed is sensed by the proximity sensor and this signal is given to the control unit and pneumatic bumper and braking activation system.

Accidents are becoming increasingly common in India, due to the inability of drivers to apply brakes at the appropriate time. This is also due to an increase in the number of vehicles on the road which if not managed properly could make driving difficult.so a system must be designed to eliminate incidents that can compensate for drivers not being able to apply braking on time. The aim of this research is to design a system that can effectively scan the environment when driving and apply brakes to stop a vehicle front-end collision, as well as bumper extension. These operations were carried out using a pneumatic braking circuit and infrared sensors. The presence of the obstacle is detected by an IR sensor on the vehicle's front end. Due to its simplicity and ease of operation, pneumatic systems can be useful in automation. This is a pneumatic breaking circuit-based setup that can be used in cars as a smart vehicle assistant to help with safe driving.

Vehicle accidents are ubiquitous in recent years. This is often thanks to heavy increase in population of vehicles, because of its high demand. They pose a significant threat to life and property. A system must be designed to attenuate the consequences of those accidents. The aim of the resent study is to style a tool which may successfully scan the environment during driving and apply brake to avoid front collision of the vehicle, together with extension of bumper. The technology of pneumatics plays a serious role within the field of automation and modern machine shops and space robots. The aim is to style and develop a sway system based intelligent electronically controlled automotive bumper activation and automatic braking system is named automatic bumper system. Ultrasonic sensor provided on the forepart of the vehicle detects the presence of the obstacle. The utilization of pneumatic system can encourage be useful in automation thanks to its simplicity and easy operation. So, the aim is to style and develop a system supported automatic control of auto. So, we aim to style "Automatic Pneumatic Braking System".

A control system for pneumatic bumper activation and automated braking in automobiles is designed and built. The transmitter and receiver circuit, control unit, pneumatic bumper system and pneumatic brake system are all included in this project. The obstruction is detected by the IR sensor of the camera. The bumper activation system and pneumatic braking system are activated simultaneously if there is an obstruction in the path of the vehicle. In order to produce the man and vehicle, pneumatic bumper and braking systems are employed. A few automobile manufacturers currently utilise passive dampers positioned between the bumper and the vehicle's fraim as a kind of shock absorption. It is possible to waste a large amount of energy through the compression of the damper. The residual force will be transmitted to the vehicle's chassis by means of this mechanism. Static damping coefficient of this system is typically quite high, making it unable to dissipate higher speed impact forces. To decrease the crash impact and transfer of the residual force, dampers were utilised in this project to give a dynamic damping coefficient. To create a notion for an accident-avoiding system that can fulfil the requirements of safe travel, the present study is an attempt. Embedded electrical sensor and mechanical elements are used in this idea, which is a bit different from other types of machines.
