Abstract: |
In recent years, the evolution of autonomous vehicles has led to a growing interest in advanced braking systems, such as brake-by-wire (BBW), which offer significant advantages in terms of efficiency, safety, and maintenance. This thesis focuses on the modeling and simulation of a brake-by-wire (BBW) system using the MATLAB and Simulink environment. The main objective of this thesis is to develop a detailed model of the BBW system, based on electromechanical brakes (EMB), design an advanced control strategy, and integrate this into a BEV model, validating the system through simulations. The adopted methodology initially includes the design of the EMB system, with the creation of an accurate mathematical model of its main components, including the electric motor, the actuation system, and the control electronics. Subsequently, the EMB model is integrated into a complete BEV model to simulate the system's response to various operating conditions, accurately representing the vehicle's dynamic behavior. A rule-based control strategy, capable of understanding braking intensity, is developed to ensure the distribution of braking demand between the EMB system and regenerative braking. The results obtained demonstrate that the proposed model can faithfully replicate the dynamics of the BBW system. Furthermore, the implemented control strategy allows for battery SOC savings. In conclusion, this thesis contributes to the understanding and development of BBW systems for battery electric vehicles. The results obtained have potential implications for future research and applications in the field of advanced braking systems for electric vehicles. |
