Construction and Performance Test of an Automatic Collision Avoidance Vehicle to Prevent Accident

Abstract

The main aim of the project to develop a system automatic accident avoidance car using ultrasonic sensor. Whenever any obstacle is detected in running vehicle depends on distance automatically control the speed of vehicle. The ultrasonic sensor system continuously sends signals and monitors any car or other obstacles are in front of car. The distance up to which ultrasonic sensor can work may be up to 50 cm. When any obstacle or vehicle detected by ultrasonic sensor system it will send signal to the Arduino pro mini controller. After receiving this signal embedded board sends a signal to the motor to reduce the car speed automatically which can control car speed immediately. Vehicle is controlled automatically without any manual operation when the vehicle is at 50cm distance away from the front vehicle. When the car come closer to an obstacle then it will reduce its speed 50cm to 30cm distance, if obstacle don’t move in-front of the car then our vehicle will stop automatically. Many accidents at High-ways are taking place due to the close running of vehicles, all of sudden, if the in front vehicle driver reduces the speed or applied breaks, then it is quite difficult to the following vehicle driver to control his vehicle, resulting accident. To avoid this kind of accident, the warning system, which contains alarm and display system can arrange at rear side of each and every vehicle.
