A CDE Definition
An IEEE standard for in-vehicle communications using Ethernet. Expected in the 2018 time frame, the 1000Base-T1 specification from the 802.3bp committee provides Gigabit Ethernet transmission over unshielded twisted pair cables. The high-speed 1000Base-T1 is designed to co-exist with lower-speed 100Base-T1 (100 Mbps) systems throughout the vehicle. See 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.
