This bachelor thesis focuses on the design and implementation of an analytical predictive model-based approach for vehicle braking dynamics control within Autonomous Emergency Braking (AEB) systems. The primary objective is to compare the proposed model with a conventional reactive system, which triggers braking interventions based on instantaneous threshold violations, resulting in shock mechanical discomfort for the passengers and a severe collision risk under reduced adhesion conditions. Within the scope of this work, a hierarchical control architecture was developed, where high-level state logic coordinates logical, hybrid, and continuous processes. The predictive algorithm itself utilizes a structural white-box vehicle model, conceptualized as a 1 DOF material point, to analytically calculate smooth braking trajectories in real time. Simulation verification in MATLAB/Simulink across four operational scenarios demonstrated that the predictive model completes the braking maneuvers with a smooth acceleration profile, and with kinematic jerk values remaining safely below the comfort threshold 2.5 m/s^3. In contrast, the reactive model generates critical shocks well above the specified limit and induces massive oscillations of control variables due to anti-lock braking system (ABS) interventions, which causes a significant kinematic discomfort.
