automotive EthernetThe use of Ethernet networking in a vehicle for its information and entertainment systems. When fully developed, 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 is used for diagnostics and firmware updates when the vehicle is 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 single pair Ethernet and 802.3bv). See ECU and Ethernet.
