Current projections indicate that by 2020, more than 120 million cars will be equipped with Ethernet connectivity, with the premium segment connecting up to 35 systems with Ethernet, and in mid-range vehicles, between 8-20 systems. Ethernet is well-qualified to serve as the bus of choice for next-gen vehicles because it delivers the necessary capacity, performance and versatility unavailable from CAN bus, FlexRay, MOST, J1850/1939 and other semi-proprietary protocols. This article will show how Ethernet can meet the requirements of tomorrow’s vehicles and how it will shape the evolution of automotive networks over the next 5-10 years.
