The evolution of in-vehicle networking has seen Ethernet transition from a single application solution to a foundational technology across various automotive domains. Initially, Ethernet was employed in limited areas such as diagnostics and in-vehicle infotainment systems, where its high bandwidth capabilities relative to legacy protocols were advantageous. However, as the automotive industry progressed, the need for a more robust and scalable communication network became evident.
With the advent of advanced driver-assistance systems (ADAS), autonomous driving features, rich data intensive applications and high speed mobile connections, data demands have increased within vehicles. These developments highlighted the limitations of legacy systems and underscored the necessity for a more capable networking solution.
Over the last 14 years, Ethernet’s proven automotive reliability and scalability have led to its broader adoption across various vehicle domains. Its ability to support high-speed data transmission makes it ideal for connecting multiple systems that require substantial bandwidth and low latency. For instance, the implementation of zonal architectures, which streamline wiring and reduce complexity, relies heavily on Ethernet to manage communication between different zones within the vehicle.
The rapid growth in data-intensive applications has accelerated the shift towards multi-gigabit Ethernet solutions. Standards such as 2.5GBASE-T1, 5GBASE-T1, and 10GBASE-T1 have been developed in IEEE to meet these increasing bandwidth requirements. This enables features like zonal architecture and rich central compute applications and services requiring high bandwidth, low latency data from the distributed ECUs in the vehicle.
The adoption of Ethernet in automotive networks has been remarkable. Over the past decade, hundreds of millions of automotive Ethernet ports have been shipped, reflecting the industry’s confidence in this technology – so much so that every global high volume car manufacturer has deployed Ethernet in their vehicles.
Ethernovia’s range of automotive Ethernet products covering PHYs and Switches provide the building blocks required by OEMs to build the next generation of automotive networks for their vehicles. These devices will further accommodate the growing data needs of modern vehicles, supporting advancements in connectivity, automation, and safety features.
In summary, Ethernet’s journey in the automotive industry illustrates a transition from limited, domain-specific applications to a comprehensive networking backbone.
