Poll Are You Interested in Learning About Automotive Ethernet?

Defined by the OPEN Alliance SIG, Automotive Ethernet, or IEEE 802.3bw (formerly BroadR-Reach), is an Ethernet physical layer standard designed for automotive connectivity applications, such as advanced safety features, comfort and infotainment features.

Automotive Ethernet enables multiple in-vehicle systems to simultaneously access information over an unshielded single twisted pair cable. The benefits for automotive manufacturers include reduced connectivity costs and cabling weight, with greater signal bandwidth.

To achieve greater signal bandwidth, Automotive Ethernet utilizes a full-duplex communication link over a twisted pair cable with simultaneous transmit and receive capabilities with PAM3 signaling. Full-duplex communication with PAM3 signaling can make visualization of Automotive Ethernet traffic and signal integrity testing very complex.

Poll Question: Are you interested in learning more about automotive Ethernet?

Full-duplex communication link over a single twisted pair cable? Now you have my attention!

I'm interested in most things - so this is no exception !

A quick Goog shows that PHYs with standard MII, RMII, RGMII interfaces are available, eg TI DP83TC811R-Q1.
This TI chip has lots of interesting diagnostic stuff but it's a lot pricier than a classic 100M Ethernet PHY.

It should be possible to hook one of these up to a micro with a standard Ethernet MAC quite easily.

I run a robotics club.
Learning and sharing real life applications is what life is is about.
Maybe we can build hobby cars & robots using a similar platforms and philosophies.
I already have built hobby cars with automatic object avoidance, auto slowdown, and auto stop on object detection (altho I wish I could get automotive sensors as cheap as hobby sensors )
Vision systems on hobby cars and robots are doable too, using examples from PyImageSearch, DonkeyCar, and PixyCam.

Autonomous vehicle control is going to be interactive with sensors networks, GUIs, and vision systems.
Wouldnt it be exciting to homebrew the same automotive control systems into Power Wheel cars and smaller RC models to show off at Maker Faires, schools, and universities ?
Lets do it !

I've worked with can bus', so I'm interested in learning how it compares to it

I always interesting in learning - even if it's something I'm unlikely to encounter.

Having said that, I thought I wouldn't encounter Modbus TCP/IP, but the knowledge I gained on E14 unexpectedly made itself useful in the middle of a conference call a couple of weeks ago.

As goes the automotive industry, so goes segments of industrial equipment. We are already using Ethernet between HMI's in marine propulsion applications. This will just be the next evolution.

Automobiles represent one of the largest technology purchases most of us ever make. This industry is a massive employer of technical people, there is continuous technical innovation in this industry with lots of spin-offs to other industries and lots of spin-ins from other industries and it is very useful and interesting to try to keep up what is happening in the automotive industry.
Just like CANBUS, automotive ethernet could have many applications outside of the automotive industry. Think rugged, low-cost wearable connectivity.

My answer is "Yes". I'd like to know more about what's going on with all the electronics. The manual for the entertainment system is twice as big as the automobile manual for my car. And from an ethical hacking point of view, I think we need more informed people.

(My possible but out of date answer could have been: I started coming to e14 for rPi and BBB only, but that has changed.)
