Abstract
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 frame 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.

Summary
One of the most essential purposes of a vehicle's braking system is to properly stop the vehicle when it is moving. Since the height of the vehicle is higher than that of other vehicles, the rear view cameras are unable to show the image properly and the vehicle will not brake automatically, increasing the risk of an accident. The model is completely parametric and may be used to test for varied levels of adhesion It is exported as c-code and integrated into an HIL system to provide an efficient test platform for the electronic Brake Control Unit [4]. A solenoid-operated pneumatic braking system is installed to maintain vehicle speed and prevent accidents. An signal of high speed is presented, and automated braking is done by shutting off the fuel supply to an engine when its setup speed is surpassed, according to our project design. A solenoid valve and an operational amplifier circuit employing LM324IC are utilised in our project [5]
