Three girls of MIT’s Sri Savitribai Phule Polytechnic institute have designed a low-cost intelligent brake assist system to automatically control speed of a moving vehicle, and reduce impact in case of a collision.
Pallavi Deodhar, Pooja Misra and Bhagyashree Deshpande are in their final year of the three-year Electronics and Telecommunication diploma course. “The statistics of road traffic accidents from India reveals that last year 1,42,000 people lost their lives in road accidents. This can be due to reasons like driving under the influence of alcohol, speeding, stress, and sleeplessness among cab drivers… We though about making something to prevent such deaths. That is when we thought of an intelligent braking system,” said Pallavi.

The project won the second prize at the DIPEX competition in Nashik. “We designed the hardware. Coding was hard for us and Vikas Madke, our mentor, taught us coding,” added Pallavi.
Pooja said, “We placed an ultrasonic sensor in front of our prototype. Ultrasonic waves sent from the device deflect back when it hits an obstacle. The car automatically reduces speed and at a critical distance, brakes automatically. We placed IR sensors on both sides of the vehicle so that any obstacle about to collide with the car is detected and the car automatically shifts to the opposite lane.
