Ultrasonic Anti Crashing System For Automobiles

Abstract: Obstacle detection has been the topic of much research in the past and new ways for avoiding various types of obstacles in various surroundings have been experimented upon . But the focus has been mostly on obstacle avoidance by autonomous agents and that too was mostly limited to extruding obstacles. These tended to make the detection mechanism very system-specific and not much suitable for general purposes. In fact , even if the user has adequate control over a device , he/she may still benefit from such a detection mechanism. Now though much work has been done for detecting various sorts of protruding obstacles , depressed obstacle detection has been somewhat neglected. This project focuses on building an user-friendly device that specializes in detecting intrusions besides doing close range obstacle detection. Automobile safety can be improved by anticipating a crash before it occurs and thereby providing additional time to deploy safety technologies .Warnings can be like buzzer if the driver is approaching a pothole or any obstruction, driver may be warned in advanced regarding what the road entails. The project‟s ultimate aim thus finalized as, one to build a general, easy-to-use and versatile system that detect potholes, besides close objects , and give warning to the user accordingly.
