The evolution of driver assistance technologies has significantly transformed modern mobility, progressively shifting from simple mechanical aids to sophisticated electronic systems capable of supporting the driver in complex environments. Among these technologies, Autonomous Emergency Braking (AEB) has emerged as one of the most impactful safety systems, designed to detect imminent collisions and autonomously apply braking to mitigate or avoid impact. As road networks become increasingly complex, and traffic density continues to rise, the role of AEB in enhancing safety and reducing accident severity becomes even more crucial. This thesis investigates the behaviour and performance of AEB systems within a virtual testing environment, leveraging the SUMO (Simulation of Urban MObility) traffic simulator, MATLAB Simulink, and their integration through the TraCI interface.
