Collision Control and Collision Avoidance Using Ultrasonic Sensor

The 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 IR sensors placed in the car, where IR 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 the brake within the safe limit. The GSM provides warning message when the safety distance is reduced than safety limit. The overall system is controlled by ARM 7 and information is displayed on LCD.
