Desenvolvimento de um sistema de frenagem de emergência baseado na distância de colisão utilizando a metodologia Model-V

Abstract

This work proposes the development of an automatic emergency braking system based on collision distance, using the V-Model methodology as the foundation for the development process. The justification for this approach lies in the need for more precise and adaptable solutions for different types of vehicles, since traditional systems are often based on the time to collision, disregarding variables such as vehicle weight, speed, and braking capability. The main objective is to implement a system that uses braking distance as a critical parameter for activating emergency braking, providing a more effective and safer response in imminent risk situations. The adopted methodology follows the stages of the V-Model, allowing continuous validation throughout the development process, from requirements specification to field testing. Automotive sensors, such as radars, were integrated into the system to provide real-time data on distance and relative speed between vehicles. The braking algorithm was calibrated based on adjustable parameters, in order to adapt the system’s behavior to the specific characteristics of each vehicle. Experimental tests were carried out with a real vehicle at different speeds and braking pressure levels, enabling the validation of the proposed solution's effectiveness. The results showed that the system is capable of accurately identifying risk situations, triggering braking efficiently and contributing to reducing the risk of collisions. It is concluded that adopting an approach based on collision distance and customization through configuration parameters provides greater precision and flexibility to the emergency braking system, representing a significant advancement over traditional methods.
