Speed Control and Automatic Accident Avoidance of Vehicle Using Multi Sensors

Abstract

The main aim and objective of this is to develop a system to safeguard the people in the vehicle from getting into accidents, to develop a system automatically controls the speed of vehicle and avoids accident using eye blink sensor and ultrasonic sensor. Whenever any obstacle is detected close to the vehicle, system automatically controls the speed of vehicle. The driver in sleeping or drowsy position the eye blink sensor detects the eye, if the driver’s eyes are not blinking for 10sec, gives alert alarm to driver and vehicle is stopped automatically, if it is not done manually. 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 4 meters. When any obstacle or vehicle detected by ultrasonic sensor system it will send signal to the embedded board. 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 4-meter distance away from the front vehicle. Also gives alarm to alert the driver. Many accidents at High-ways are taking place due to the close running of vehicles, all of sudden, if the driver in front vehicle reduces the speed or applies brakes, 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. If any short circuit occurs in engine part or the driver is smoking smoke sensor detects it and gives alert to driver and stops the vehicle.
