Trabalho completo:

A evolução da indústria automotiva tem sido impulsionada pela crescente complexidade dos veículos modernos, que dependem de sistemas eletrônicos para funções críticas e de segurança exigidas por legislações. Esses sistemas variam desde unidades de controle básicas até Sistemas Avançados de Assistência ao Motorista (ADAS), necessitando redes de comunicação confiáveis, eficientes e de alta largura de banda para operar de forma integrada. Nesse contexto, os protocolos de rede veicular tornaram-se a base da eletrônica automotiva moderna. Este artigo analisa o papel da Ethernet nas redes automotivas, abordando seu conceito, aplicações, vantagens, desvantagens e sua comparação com protocolos como CAN e LIN. A transição para sistemas de infoentretenimento avançados, atualizações Over-The-Air (OTA) e ADAS impulsiona a adoção da Ethernet, apesar dos desafios ligados a custo, complexidade do chicote elétrico, compatibilidade eletromagnética, cibersegurança e integração com protocolos atuais. No entanto, uma abordagem híbrida, que usa protocolos convencionais para tarefas sensíveis à latência e Ethernet para operações intensivas em dados surge como solução equilibrada, direcionando a tecnologia automotiva rumo a maior automação, conectividade e funcionalidades voltadas ao consumidor.

The rapid evolution of the automotive industry has been driven by the increasing complexity of modern vehicles, which now rely heavily on electronic systems for critical and safety functionalities required by legislation. These systems, ranging from basic control units to Advanced Driver Assistance Systems (ADAS), demand reliable, efficient, and high-bandwidth communication networks to operate seamlessly. In this context, in-vehicle networking protocols have become the backbone of modern automotive electronics. This paper analyzes Ethernet?s role in automotive communication networks, focusing on its concept, applications, advantages, disadvantages, and how it compares with common protocols such as CAN and LIN. The shift toward data-intensive infotainment systems, Over-The-Air (OTA) updates, and ADAS drives Ethernet adoption, although challenges persist in cost, wiring harness complexity, electromagnetic compatibility, cybersecurity, and integrating current protocols with newer Ethernet frameworks. Ultimately, a hybrid approach that uses conventional protocols for latency-sensitive tasks and Ethernet for data-intensive operations emerges as a balanced solution, guiding automotive technology toward higher levels of automation, connectivity, and customer-focused functionality.
