Abstract—Through this our expectation is that the car should break automatics if any obstacle detection as per sensor input.It should also break if the car does not follow driving track and re-track car. If the above said condition it should generate alert message for immediate help and send that message to a predefined mobile number.In that SMS it is should send current place latitude and longitude obtained from GPS so using that latitude and longitude,we can find its location on earth and we can provide fast help in case of emergency. The Microcontroller PIC18F26K22 is interfaced with a track sensor that continuously detect, track, vehicle is in motion if track sensor output detect off road path,then microcontroller immediately slow down vehicle speed and try to move the vehicle back on path depending on track sensor output. Also microcontroller interfaced with IR sensors to detect any obstacle is present in vehicle path, is in movement.
