Comparative study of different controllers in an autonomous vehicle system

Abstract In recent days the entire world moving towards autonomous driving vehicle. For the last decades, the world started more research on Autonomous or Auto-pilot vehicle. It faces lot of challenges to design such a system. In recent, Google and tesla designs an autonomous vehicle in the name of waymo. The main aim of this research work is to provide healthy transportation with high safety and security. This waymo vehicle is now under testing with conditional and unconditional environment. In this paper it is focused on a controller part to take care of the vehicle in critical and non-critical environmental situation. In this perception, this research gives the overview of the various controllers with its merits and demerits. The controller is to imitate like a human driver. Normally the human eye focus on mobile and immobile objects, road sign, pedestrian etc., the controller need to focus the road condition, optimal steering control with less tracking error and cruise control.
