Evaluation of Automated Emergency Braking Systems for Collision Avoidance 2024-26-0185

From the past few years, there is a pressing need for implementation of automatic in-vehicle safety systems to avoid vehicle crashes and fatalities. Development of autonomous emergency braking systems (AEBS) to detect and avoid collisions in such critical moments is of paramount importance. In this paper, AEBS is developed for a four-wheeler system that aims to detect vehicles and controls the ego vehicle based on the expected stooping distance (ESD). This control system aims to react based on the real-time relative distance & speed of the ego vehicle to actuate appropriate braking force. Control systems developed in Altair Activate are co-simulated with CARLA, a virtual reality simulator for autonomous driving research. Various scenarios including low and high-speed car to car motion, urban high and low traffic density environments are simulated to study the robustness of the control system. Further, studies are conducted to evaluate the effectiveness of the systems by varying the activation threshold, distance etc. The results of this evaluation demonstrate the effectiveness of the AEB system in reducing the severity of collisions, and the system’s ability to function correctly in different scenarios. Later, suitable modification to the control system is suggested in case ESD is very high when compared to Stopping distance.
