Intelligent Braking System Using Electromagnetic Actuators

The accident prevention has been one of the leading areas of research today. Our paper is designed to prevent accidents due to loss of control, drunken driving, and rash driving, using circuitry aided by a microcontroller kit. This paper focuses on a system known as ‘Intelligent braking system’ (IBS) which employ several sensors to respond when emergency conditions occur. In our work, braking distance and the distance of the obstacle are taken into consideration along with the speed of the vehicle. The sensor detects speed of movement of the vehicle and the ultrasonic sensor senses the distance of the object in front of vehicle. These sensors provide real- time inputs to the microcontroller program. Using sensor, the system will sense the speed of the vehicle and with the microcontroller, it will calculate the distance required to bring the vehicle to a complete stop for that speed. An intelligent mechatronic system includes an ultrasonic wave emitter provided on the front portion of a car producing and emitting ultrasonic waves frontward in a predetermined distance. An ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle and RPM counter gives speed of vehicle. The reflected wave gives the distance between the obstacle and the vehicle. Then a microcontroller is used to detect the pulses and apply brakes to the vehicle the breaking motors is incorporated to activate the brakes thereby achieving automatic breaking 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. 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.
