Recent Advancements in Autonomous Emergency Braking: A Survey

Background/Objectives: This paper is aimed to present a study on the need for Autonomous Emergency Braking System (AEBS) in Autonomous Vehicles (AVs), terminologies, important AEBS metrics, and recent research on AEBSs in AVs. Methods/Statistical analysis: This paper discusses the AEBS research carried out in the recent past, with integrated technologies. The study articles are sourced from databases like IEEE Xplore, Springer Link, Science Direct, and Elsevier Journal Finder, etc. The keywords used to fetch the relevant articles are: autonomous vehicles, self-driving vehicles, automatic emergency braking, autonomous emergency braking system, and collision avoidance in AVs. The surveyed literature was published between 2009 and 2020. Findings: The observations in this study reveal the following: various tools used to simulate AVs and AEBSs, widely adopted metrics for consideration and evaluation, real-time implementations of AEBS (sensors and prototypes), and different technologies used for the effective implementation. Novelty/Applications: The detailed study on AEBS in this paper emphasizes various interesting factors to make AEBS more robust and reliable. The findings are outlined in the summary section as the future research agenda. Hence, there is a great room for effective AEBS implementation with the blend of our findings.
