Your Next Car's Electronics Will Likely Be Connected By Ethernet 180

Lucas123 writes "As the sophistication of automotive electronics advances, from autonomous driving capabilities to three-dimensional cameras, the industry is in need of greater bandwidth to connect devices to a car's head unit. Enter Ethernet. Industry standards groups are working to make 100Mbps and 1Gbps Ethernet de facto standards within the industry. Currently, there are as many as nine proprietary auto networking specifications, including LIN, CAN/CAN-FD, MOST and FlexRay. FlexRay, for example, has a 10Mbps transmission rate. Making Ethernet the standard in the automotive industry could also open avenues for new apps. For example, imagine a driver getting turn-by-turn navigation while a front-seat passenger streams music from the Internet, and each back-seat passenger watches streaming videos on separate displays." This might get us into trouble when the Cylons show up.

    This article is about the L1 PHY layer, not the L2 Data Link layer. There is no reason to assume this means your car will be using TCP/IP. The diagram in TFA clearly indicates that the PHY layer being discussed here is independent of the protocol.

    In fact, the included diagram seems to indicate broadcom is pitching some kind of adapter device which would enable inclusion of the new L1 layer with no changes whatsoever to the programming of the devices on either end. One would hope that such a thing would be only considered a stop-gap measure while they reworked their components to use the new bus natively in future models. History clearly shows that such adapters tend to be inefficient.

    Connectivity used when shit has to just work all the time, regardless how many hipsters are in the area.
