Abstract
This paper proposes an intelligent collision avoidance system as a prototype, which avoids vehicle accidents and to provide a greatest security to the user in adverse or bad weather condition. Here, Ultrasonic sensor and vibration sensors placed in the car, where vibration sensor is used to detect the lane and avoids accident in significant manner. The vehicle state information is obtained using Ultrasonic sensor, which will continuously track for any obstacle from front side. If the obstacle is detected then microcontroller will continuously compare the distance given by Ultrasonic sensor. If the obstacle is closer to the car then the microcontroller will start applying safe limit conditions. The obstacle distance is 2cm the image captured by webcam and Obstacle details are sent to the user through Email by using GSM. If the distance is 5cm buzzer will be switched ON. The distance is 10cm send the phone call to user. The overall system is controlled by PIC and information is displayed on LCD. The vibration sensor with certain range of accelerating is fixed in the vehicle. When the vehicle is dashed with another or any other obstacle the vibration sensor detects whether the vibration is limit within range or not. It is greater it reports as accident and activate the auto dialer
