Driver distraction, or misjudgment is the most common causes of car accidents. As a result, the research and implementation of vehicle safety systems have accelerated in recent decades, making Advanced Driver Assistance Systems (ADAS) critical for improving road safety. The study here focuses on, how to test ADAS, namely Autonomous Emergency Braking System (AEBS), by taking into account, things like, appropriate test environments, and traffic scenarios, as well as verification, and validation methodologies. For simulation, we have used IPG Carmaker to measure the braking efficiency of the vehicle, on a curved road path. In this paper, Ackermann’s geometry and Bicycle Model are also studied, in order to understand the dynamics of the vehicle, to enhance the accuracy of lateral distance estimation, especially during curved maneuvers.
