Continental to roll out Ethernet in all automotive domains

Continental to roll out Ethernet in all automotive domains Automotive supplier Continental AG has provided details regarding the roll-out of Ethernet as the technology for in-car networking. The company also announced plans to replace MOST as the current infotainment networking technology by Ethernet.

The increasing bandwidth requirements, driven by next-generation camera-based driver assistance systems in the first place, make Ethernet the ideal means for data networks in vehicles, Continental said. With a robust bandwidth of 100 Mbit/s and the usage of simple, cost-effective unshielded two-wire copper cable, Ethernet will connect all relevant ECUs, antennas and sensors, the company explained. With this position, Continental was among the first tier ones to commit to Ethernet; the company announced to support Ethernet already earlier this year.

Now Continental has submitted a kind of roadmap for the roll-out of Ethernet. In the first step, the electronics provider plans to equip the Interior and chassis & Safety domains with Ethernet since in these domains wiring is a relatively easy task. Later, the cars could be networked entirely with Ethernet, doing away with technologies today in use but with much lower performance. For these the next steps, the relatively long automotive design cycles apply: First products will be available in 2015. Gradually, Ethernet will conquer all automotive domains. "Until 2020, we can imagine to have first pre-development projects with Ethernet in all domains", Continental writes in a press release.

Ethernet would make a plentitude of benefits available to carmakers - benefits that other segments of the IT world already could use for decades but were not accessible for in-car networking designers because of the extreme EMC requirements in vehicles. "Ethernet will help to reduce the total vehicle costs and at the same time increase functionality," explained Continental board member Helmut Matschi.
