Working principle:

 This system is used at the time of emergency during work. In normal travelling of vehicle this system is off and it never impact on the normal working. When any obstacle, humans, animals or vehicle is came in front of the vehicle then the installed infrared sensor senses that obstacle the received signal by IR sensor is provided to the control unit. This control unit operates the relay according to the input signal. The relay operated by control unit cut off the electric power supply given to the engine so the working of engine is stop. When the engine stops the working the motion of vehicle suddenly reduces. At the same time of working of IR sensor the driver also applied the brake so braking system works by two methods. There is some incidence when the working of automatic braking works and engine running is also stop but due to the moment of inertia on vehicle tries to forward motion of the vehicle. This inertia motion causes accident. During such incidence the driver also uses manual braking system. In this manual braking system limit switch is also installed below the brake pedal. By receiving the foot force of driver the limit switch activates and provides the signal to the solenoid control valve. Solenoid control valve open sport going towards the bumper system and brake shoes. This pneumatic force used to forward motion of the bumper. By receiving the impact of accidental force bumper try to deflects. The flexible nature of the bumper able to sustain the force and so the impact of this force on vehicle is reduces. When the external body is kept safe then there is no chance of inner damage.
