Design and Implementation Issues in Autonomous Vehicles- A Comparative Review

Advanced methods like autonomous cars are usually designed as a composition of characteristics which are independent functionality units. Functionalities prefer to interact and unknowingly impact each other's behavior. But the major problem is to detect and handle the functionalities interactions, especially those that breach the system requirements, resulting in failure. In this paper, we will review the current technologies used for autonomous cars including design issues, testing and implementation. Based on our review, we have highlighted the various issues involved in the design and implementation of autonomous vehicles based on the parameters of map, cost and software complexity. We believe that our review will help researchers in the field of autonomous vehicles to refine works in state-of-art towards better implementations.
