Development of Accident Preventive Bumper

Mechanical Engineering

Now-a-days, accidents taking place are very frequent in India which occur mainly due to the inefficiency of driver to apply brakes at the right time. To prevent the accident, there is no provision to apply brakes when the driver fails. Also, In currently used vehicles generally bumpers used are of rigid types. These bumpers have specific capacity and when the range of the accidental force is very high then the bumper fails and the force is transferred towards the passengers. So the current system never reduces the damage of both vehicle and passengers. To overcome these two problems development of automatic bumper and braking is important. Therefore, the aim is to design and develop an electronically intelligent braking system which can automatically sense the objects ahead of the vehicle and applies brakes itself to avoid collision. The system also activates extractable bumper which may extract and reduces the damage to the vehicle’s body. This bumper may extract or retract with the help of using Pneumatics technology which is much easier to implement and is readily available easily. Automatic braking system use the infrared sensor (IR), which is used to sense the vehicle coming from front of our vehicle and which is responsible for accident. Then sensor sends feedback signal to the control unit and activates the solenoid valve. When the solenoid valve gets actuated, the compressed air goes to the pneumatic cylinder and actuates it. During the working of Automatic braking system simultaneously the control unit activates the pneumatic bumper system to reduce the damage to vehicle which occurs in accidents. This system provides pre-crash safety to the vehicle.
