Tracking Robot : Distance keeping with ultrasonic transceivers

Abstract: Fuel efficiency and safety in traffic is something that the vehicle industry prioritizes, although there is always room for improvements. This report presents how ultrasonic sensors could be used in road trains to keep distance between vehicles in order to reduce fuel consumption and increase safety. A small model in the size of a radio controlled car has been built to evaluate how this technology works in small scale. The results indicate that this can be done, and discuss the advantages and disadvantages with this technology in road trains.
