- In-vehicle Networking Technologies Compared - AutomotiveEthernet (100BASE-T1, 1000BASE-T1, 10BASE-T1s), CAN-FD, LIN, FlexRay, MOST, SerDes, A2B
We will cover a basic overview of some of the most popular in-vehicle or automotive networking technologies. Each technology is then compared to the others based on selection criteria including: costs, maximum supported data payloads, addressing methods, topologies, supported communication types, cabling considerations, versatility and others.

Excellent presentation, a wealth of knowledge delivered. Thank you!
Thank you so much man! I work in the automotive industry and wanted to know more about ethernet. Very nice explanation.
This presenter did an excellent job of keeping things relevant, simple and not getting into the weeds (like most engineers tend to do). I’ll be coming back to visit your site in the future.
great overview and summary of the technologies and trends. thank you!
Really great overview Colt. Appreciate ICS putting out valuable information for public consumption!
Well put together presentation with the right amount overview and detail.
This is just pure gold, really... Amazing video, one of the most comprehensive ones that I have seen in engineering field in general.
Thanks for the kind words!! We're so happy you found this helpful. If you're in the metro Detroit area in May, come check out more of our products and demos at our Automotive Tech Day! intrepidcs.com/techday2023
Excelent documentation and presentation! This should go up in views, it's worth it!
Thank you
Thanks for the video and presentation.
ICS has the best people in the business! Thank you for sharing your valuable knowledge with us!
Thanks for your kind comment
Just awesome. Thank you very much.
Thank you for this comprehensive explanation! Means a lot!!
Always happy to help! Let us know if we can assist you in any other ways or if you'd like to schedule a demo with our experts (:
brillian! tahnks so much for such a good video and explanation
I am new to Networking topic and was looking for a good overview and the necessity of each type of network. Thank you so much for the presentation, it was highly useful!
Thank you Aditi, We are adding new videos every week on our RUclips channel. Feel free to like and subscribe our channel.
Really nice. This is worth for automotive SW engineer.
Excellent presentaion !!
Thanks a lot for this amazing video, it was very helpful
Really good and helpful talk. I think you missed out on one important part of why Bosch chose CAN be a bus-topology. In a car, you have dozens to hundreds of CU's from different vendors and as an OEM you want to keep the vendors interchangable. So you need a lot of one-to-many communication, information like board voltage, vehicle speed, tire speed is measured at one node and is communicated with all devices.
So for the board voltage example, you could either choose:
CAN with one sensor for voltage and a message that is received by 100 nodes.
Ethernet with either one sensor on each node or layers of switches with 100 end nodes.
I'm certain that Ethernet will be the dominant backbone of a car from now on, but the way CAN work leaves some benefits that Automotive Ethernet needs to fill in.
Are you Beamspot?
Manuel - thank you for the comment. I will include this info in the future.
Thanks sir. It is a great video and technoligies information.
Thanks ✌🏻
Great presentation. Looking forward to checking out the 2nd addition. Any updates on when it will become available?
We will keep you posted, but we are still planning for sometime this year.
Could I ask: what is some/ ip's location in the picture of Vehicle Networking Technologies?
I try know the marketing for future electric vehicles
Awesome, is that book you showed, does it cover autosar details as well. thanks.
Chapter 6.4.4 covers AUTOSAR but we are working on 2nd edition of the book that will cover alot more about AUTOSAR. You can read the sample here cdn.intrepidcs.net/brochures/icsusa/Sample-AutomotiveEthernet-TheDefinitiveGuide.pdf
Hello Mr. Correa,
I currently work for an interior company (tier I) to OEM's and I want to focus into lighting and electronics, your video has helped me a lot to understand regarding software technologies but is there a training or Master Degree maybe that you would recommend please? I studied international trade so is hard for me to keep up technically with these topics
Message from Colt "Thank You, I do not have any suggestion on training"
Just curious, from a technicians standpoint, if canbus and flexray are both a max of 10mb/s is the oscilloscope the issue why we need a specific lead for flexray, whereas with canbus regular scope leads seem to be fine when capturing communication waveforms? Specifically Pico scope. maybe a dumb question, but Ive also had no issues capturing canbus on a slower handheld hantek oscilloscope. FlexRay seems to be the exception and the leads for it are pretty expensive.
CAN FD can hit 10, but normally is not ran that fast. 2M is more common. I have scoped FlexRay with a Pico scope. I have never seen CAN-FD at anything close to 10M.
@@arpanrughani7477 So are these specialized FlexRay leads unnecessary? I read somewhere these leads were needed to view FlexRay waveforms, and I didnt really understand if CAN is the same speed why would we need to speed so much extra on leads you might use once a year.. Does it depend on the Pico Scope model, I mean even the 10Mhz scope should work then.. Maybe Im wrong..
@@alanw5879 If the baud rate is 10M, you would want a faster scope. 10M is 100ns per bit. Sampling at 10Mhz, 100ns per sample. You need more than one sample per Bit. 2 would be a minimum (Nyquist-Shannon Theorem) but realistically you would would 10-100 or more to get a good picture. Flexray is differential, so 2 lines. The more feature filled probes will have some filters and look to do the adding in the probe. So rather than using 2 probes and adding on the scope, which will take twice the samples per second, you can use one channel and more samples per second to get a better picture. Automotive ethernet is a different story, you do need fancy equipment for.
@@arpanrughani7477 ok I see what youre saying, watching CAN bus we have the differential, High and Low so the difference really is the ability to watch both those signals on one lead freeing up another channel as well as some sampling amount. Thanks for clearing that up for me. I appreciate it. I use my scope on as many diags as possible, Its really amazing how much we can do with a scope now for automotive purposes. Never thought Id be able to see a bad head gasket on a scope. cool stuff... Thanks again.
When will the new book be ready?
The second edition will come either end of this year or early next year.
Hello
May I know how ECU 2 knew the MAC address of ECU 3?
How actually the data is transmitted?
Hello Karthik,
What slide are you referring to?
@@IntrepidControlSystems
I am not sure whether this topic is covered or not
I would like to know in general
If a new ECU is added for example
Light ECU and steering ECU
How will they come to know there MAV address
Or simply they will broadcast?
@@karthikkperla90 Please email this to icscontactus@intrepidcs.com, Someone from our Sales or Support team will be happy to answer your questions.
Hey sir i just want to know what does redundancy mean? And thank you in advance
Network redundancy is process of providing multiple paths for traffic, so that data can keep flowing even in the event of a failure.
@@arpanrughani7477 thank you sir for your help
Is it possible to speak more about time critical ethernet?
Yes we can do a presentation on that, if you like to speak with of our experts. Please fill out this form intrepidcs.com/sales
Hi, do you sell ista+ ?
We do not sell ista+, but we do sell similar products. Please reach out to our sales team by filling out this form and we can help you with your use case. intrepidcs.com/sales/
love u
Honda still use MOST network for their audio needs in their newest cars XD
Cons for Most Bus that Colts talk about in his presentation is very accurate. We will see companies switching to Automotive Ethernet instead.
You have to work more the way you present the group services, it looks like an old school power-point presentation, otherwise thank you for the presentation
Thanks for the feedback.
