Design and Implementation of Automatic Emergency Braking System

Abstract

Vehicle technology has increased rapidly in recent years, particularly in relation to braking systems and sensing systems. ASS (active safety systems) are being researched and developed to prevent accidents and target mitigation. Among many useful active safety systems, it has been reported that AEBS (Advanced Emergency Braking Systems) effectively prevents accidents and reduces casualties simultaneously. The project aims to distinguish between systems currently in production like traction control (TC), electronic brake force distribution (EBD), brake assist (BA) and electronic stability control (ESC) functions and future systems that are currently in development. The project aims to develop a prototype system that offers a collision functionality in production vehicle, a system which can operate automatically with the help of high profile sensors based relay circuit and some modification in traditional braking system that can alert the driver in front collision and apply the brake automatically in emergency or critical situation. AEBS with ultrasonic sensors (up to 10m range) and pneumatic cylinder actuation provides automatic braking. City Safety system study shows potential to prevent crashes up to 30km/h and save over 150,000 whiplash injuries annually.
