Now-a-days vehicle accidents is the major problem. Automatic Braking with Pneumatic Bumper System Using Proximity Sensor is used as novel project for the purpose of prevention of accidents happened in the restricted roadways. The system is based on an intelligent electronically controlled with automatic bumper activation system “Automatic Braking with Pneumatic Bumper System Using Proximity Sensor”, will be assembled on four wheeler vehicle. Generally this system consists of two mechanisms and these are automatic braking system and pneumatic bumper system. Automatic braking system uses the Infrared Sensor (IR) which senses the vehicles which come in front of our system and which may be a cause for accident. Then sensor gives feedback to the engine through relay to stop the working of engine. During the working of Automatic Braking System simultaneously the driver of the vehicle will also try to stop the vehicle by pressing the brake pedal. Limit switch is provided below the brake pedal which is used to activate the pneumatic bumper and disc brake simultaneously to reduce the damage to the vehicle which occurs if both vehicles collapse on each other. This provides pre-crash safety for vehicle. As well as this system improve the response time of vehicle braking to keep safe distance between two vehicles. By using this system we control the speed of vehicle in small distance.
