automotive Ethernet

The use of Ethernet networking in a vehicle for its information and entertainment systems. When fully developed in the 2018-2020 time frame, automotive Ethernet will reduce cost and weight considerably over the traditional wiring harness that supports multiple transmission systems (see MOST, CAN bus, FlexRay and LVDS).

Starting in 2010, automotive Ethernet at 100 Mbps has been used for diagnostics and firmware updates when the vehicle was serviced. In 2015, Broadcom's Ethernet-based BroadR-Reach met EMI requirements for various point-to-point links. In the future, automotive Ethernet will become the communications backbone in a vehicle, providing a 1GbE network over twisted pair or plastic optical fiber for all internal systems (see 802.3bp and 802.3bv). See ECU and Ethernet.

"Some of our test solutions will focus on battery and EV infrastructure, automotive radar, V2X communications, automotive Ethernet, and electronic board testing," he said.
These tools compliment what commercially available tools can do, by stressing the lower, typically/previously untestable physical layers, for Fast, Gigabit, and Automotive Ethernet. Previously only available internally, the public can now test their devices in the same manner that the UNH-IOL would, allowing for immediate debug in any lab around the world.
IEEE has formed a task force to develop IEEE P802.3ch Standard for Ethernet Physical Layer Specifications and Management Parameters for Greater Than 1 Gb/s Automotive Ethernet.
