Why We Need an Automotive Variant of Ethernet
Lessons
Ethernet is a widely used networking technology, but it is not without its limitations for automotive applications. In order to meet the demanding requirements of automotive systems, such as high-speed data transfer, functional safety, and cybersecurity, a specialized variant of Ethernet called Automotive Ethernet was developed. Automotive Ethernet uses a single twisted pair for both transmit and receive operations, which allows for higher data rates and lower power consumption. It also supports a number of safety features, such as time-triggered communication and deterministic latency. As a result, Automotive Ethernet is becoming the de facto standard for networking in modern vehicles.
