Comma AI/OpenPilot Update -- Watch it in Action on Gen1 Rivian (Video)

[gerrylum]

Hopefully, there's a way to get around this limitation. Otherwise, the Sunny-Lukas MADS version is great...especially on main highways.

I'm optimistic we'll be able to get around it. There were similar limitations on other Hyundai power steering columns that were able to be worked around so I hope that we can use a similar method with ours.

• Will it be merged into mainline Sunnypilot or Openpilot?
Unlikely—it will probably remain a separate, Rivian-specific branch. Of course, that could change depending on future development.

Why won't this eventually be merged into mainline of either OP or SP? Does that imply this will never be officially supported? I assume the majority of cars supported is via mainline.

"Officially supported" is a strange term to use for an open-source project. But for the sake of argument, I assume what you mean by that is support for Comma's branch of Openpilot. Comma, however, does not sell the harness modification and therefore has no reason to add support to vanilla OP.

Being eventually merged into the main branch of Sunnypilot is more likely. I guess I would relate the efforts being done on Lukas' branch for the Rivian to how Bluepilot is used to develop, test, and stage Ford specific enhancements before being submitted to the SP team to potentially be merged.

Has anyone upgraded the SSD in the 3x to a bigger SSD? I know many did it to the 3, just not sure if the 3x has been done, or if there is any reason to.

The SD memory card (not SSD)? What for? They give a spec for sizes and there's no reason you can't change it if you want.

As to the question on stop and go, problem traffic, it really shines there with the potential exception of leaving a slight bit of extra following gap than most people. I'm fine with it, the other day I had some asshole in a lifted emotional support truck tailgating me within 2' (not making that up) because he didn't like how much space I left. As if somehow being closer, put him closer to his destination. He passed me with rage and a finger, I told the Comma to move over a lane, and lady Karma showed up 45 seconds later with his lane totally stopped

Been using Filet o Fish without many issues. Looking forward to Tonb Raider 6. Been hearing good things.

I am on filet-o-fish so far as well. It has been pretty solid. I am using aggressive for the personality. It will stop short and then inch up to a more reasonable gap.

I was asking about support in the context of Comma, but you raise a good point. Coming from the software world, living in a test branch usually isn't a path for success. How are other cars added? I assume each car doesn't live in it's own fork, but eventually makes it way back to the main. I don't really understand the difference between OP and SP. Why would it merge into SP but no OP?

What happens if Lukas slows down (for whatever reason) staying current with main branch?

Not sure what you meant by “other cars being added”—are you referring to Lukas’ test branch?

If you’re asking how cars get added to Openpilot generally, it’s mostly thanks to the open-source community. That’s exactly how Rivian support happened—not by Comma, but through the work of contributors - like Lukas who did the bulk of the work porting Openpilot for the Rivian and designing the wiring harness. Comma may eventually roll in vehicle support once it’s stable, especially if it helps them sell more Comma 3X units and harnesses, but the heavy lifting was done outside of Comma.

As for why this would merge into Sunnypilot (SP) and not Openpilot (OP): Sunnypilot is a user-maintained fork, which gives the community more flexibility. Comma won’t merge features into Openpilot unless it aligns with their business model. Since Lukas’ solution depends on a harness mod that Comma doesn’t sell, there’s no incentive for them to merge that into the mainline.

As for what happens if Lukas ever slows down or, heaven forbid, stops developing - the fact that this is open source means anyone can pick up where he left off.

I can find no evidence that you can select aggressive with the Rivian selected. It behaves the same way (broken) as when you don't go through the steps to sort-of select it. I don't think it sticks at all.

Filet O Fish gets drunk at random. It did it today. In an area I drive regularly, it suddenly started driving over lines and dots. No reason I can explain (clear, daytime, etc). This is after a couple hours of driving all over town with great results.

• Is there a public issues list?
No, but there are not many issues to speak of. Beyond the 90° steering issue referenced above there aren't any glaring outstanding issues beyond Rivian-specific tuning.
.

I wouldn’t say there are no issues. While perhaps not directly related to the comma, the Rivian doesn’t seem to be happy with a comma connected. I’ve been experiencing Rivian cruise control errors and failures, including some that require a vehicle reset. While most of these errors flash on the screen and only temporarily disable all cruise control functions, it’s certainly concerning to know that they could potentially damage the Rivian and necessitate a service visit. I’m not sure how common this issue is, but I’ve read reports of others requiring a service visit after connecting a comma.

Overall, I’m enjoying the comma, but I believe it’s crucial to thoroughly investigate these issues to avoid causing any damage and requiring a service visit.

Are you submitting routes with logs when these events occur so they can be investigated?

Several people can review the logs. Lukas has done so. So while there isn't a specific SLA, there are still people who can, and want to, help.

Nope, but can look into doing that.

Totally understand. I'm not expecting specific support—I know this is a passion project and many are contributing in their own time. I’m glad to have it and plan to keep using it, but I do think it’s important to acknowledge that Rivian+Comma is still very much a work in progress and carries some risk of vehicle damage that could require a service center visit to resolve.

Do you think OSS is just operating in a vacuum? My business has been OSS-based for decades and the software has grown accordingly, with bugs addressed properly.

Are you submitting routes with logs when these events occur so they can be investigated?

Do you have a pointer to a list of things that should be submitted or not? Is my drunk driving submittal-worthy? Also I know that Lukas' fork doesn't go in Firehose, but it does get log reviews then?
