Self driving cars: A peep into the future

This paper presents a unique embedded controller design of a driverless, green energy powered, collision protected and GSM destination guided vehicle. A GPS module accurately tracks the location of the car, source and destination, and mapping the co-ordinates provides navigation Speeds of the vehicle is automatically controlled by keeping a safe distance, which is a function of speed, with the vehicle in front. Distance of the front and side vehicle are continuously monitored by a stepper motor controlled rotating distance measuring sensor and the speed limit as well as track changing are done accordingly. It also prevents collision due to an obstacle. Camera with image processing unit has been used to sense traffic signal and traffic density. The driverless car is powered by green energy from a rooftop solar PV panel with battery backup. Useful audio information also is provided to the passenger.
