A Review Paper on Automatic (Intelligent) Braking System with Gas Sensor and Alcohol Detector

Road accidents are a commonplace in today's scenario. Accident prevention has been one of the leading areas of research. Our project is designed to prevent accidents due to loss of control, drunken driving, and rash driving. Using circuitry aided by a microcontroller kit to provide a real time monitoring system. In our work, braking distance and the distance of the obstacle are taken into consideration along with the speed of the vehicle to provide the basis for calculation. The microcontroller kit is powered with a microcontroller 16PI and programmed to calculate the braking distance and take actions accordingly. The Hall sensor helps in finding the speed of movement of the vehicle and the ultrasonic sensor senses the distance of the object in front. These sensors provide real- time inputs to the microcontroller program. Using a Hall sensor the system will sense the speed of the vehicle and with the microcontroller, it will calculate the braking distance: that is the distance required to bring the vehicle to a complete stop for that speed. Braking motors is incorporated to activate the brakes thereby achieving automatic braking procedures. The system helps in conjunction with the driver judgment if the driver doesn’t sense the obstacle and applies the brake at the right time then the microcontroller initiates braking motor to apply the brakes automatically. Our future work deals with incorporating real time brake shoe wear system to provide enhanced feature for the intelligent braking system. Our Intelligent Safety concept car provides a glimpse into the future of automotive safety, and how much more advanced these individual systems can be for avoiding accidents and protecting vehicle occupants when they are integrated into one system. The future of automotive safety is more than just developing new technology; it is shifting the approach to safety. By looking at safety in terms of avoiding accidents in the first place – and then protecting occupants when a crash is unavoidable – we can prevent more accidents, save more lives, and reduce insurance and medical costs to society.
