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
