The automotive vehicles are maximized by warning systems and collision avoidance for potential collision with an object like pedestrian or vehicle. Based on potential collision, these systems typically start to ignore collision and/or offer an advice to an operator of the vehicle.

 This A NOVEL REAR END COLLISION ACCIDENT AVOIDANCE SYSTEM WITH DYNAMIC SPEED GOVERNOR project includes distance-measuring system depending on ultrasonic sound with the use of PIC 16f877A micro controller to send ultrasonic sound waves to the target and gets the particular echo. The ultrasonic sound sensor is utilized to discover on reaching echo to the system. The time taken by the ultrasonic burst to complete the distance from the system to the subject and vice versa is definitely calculated by the micro controller.

 When the distance among obstacle and vehicle passes a limit then it offers the signal of warning to the driver. It even controls the vehicle’s speed and when the speed limit increases then the driver gets informed. The speed limit is maintained by authorities for various vehicles class.

 The project “DYNAMIC SPEED GOVERNER” is the modern technique which monitors the vehicle speed externally than internally. The two PIC16F877As, RF transmitter, and a receiver monitor the speed measurement and control.

Conclusion:

This article introduces a system of to measure the distance with the use of ultrasonic sound and PIC 16f877A micro controller. This system avoids the accidents. It detects the echo on the arrival to the system. There are many kinds of vehicle speed limiters which are used today to control the traffic like malls, hospitals, and schools. This system includes a micro controller that stops the vehicle on finding that the vehicle is going to hit any other vehicle.
