Accident Avoidance Using IBS and AOCS Major Project

Accidents are increasing at a higher pace and are most common if driving is inadequate. Driver drowsiness is considered an important factor in vehicle accidents, Over Speed can also be considered as another important factor for vehicle accidents.

The main objective of this project is to develop a system for automatic speed control and accident avoidance using eye blink and ultrasonic sensors to keep vehicle secure.

It includes an intelligent braking system in which, whenever any obstacle comes in front of a running vehicle the ultrasonic sensor detects the obstacle at a distance of 4m away from it and sends a signal to embedded board or microcontroller.

And if the driver is drowsy or about to sleep, then the eye blink sensor detects the eye blink and if eyes are closed for more than 30 seconds, the vehicle stops automatically.

Apart from these, the safety of the vehicle can also be ensured by introducing A.O.C.S (Automatic Over Speed Control System). It basically controls the speed of the vehicle by continuously checking it through sensors which sends the signal to the microcontroller.

Whenever the speed is increased above the predefined critical speed, the microcontroller through its logical circuits sends the signals to the actuators via its output pins. The actuators apply necessary force on the brakes and reduce the speed to its safe value.

The sensor used in this system is an optical type infrared sensor and the actuators are stepper motors to which the output of the microcontroller is connected.
