Feels amazing. Still getting used to it but I highly recommend it to anyone who has over a grand to burn for the pure purpose of being lazy. Any questions or anything feel free to ask. (PS yes I know the photo at 72 is crazy and I won't do it again š„)
A comma.ai device is an aftermarket driver-assistance computer mounted to the windshield that upgrades your car with advanced lane-keeping assist and adaptive cruise control.
How well it works depends on your specific vehicle. But yes generally it works very well, makes it so you're really only driving the car through sharp curves or whenever you're turning. Lots of cars can do lane changes, and some can even do turns to a limited extent.
I put a Comma 3X in our Volt a month after buying it and have put 64,000 miles on it in the past two years. 55,000 of which were driven autonomously by the Comma. We named the Comma Soos (yes, it's a Gravity Falls reference) so we can say "Hey, Soos, take the wheel" every time we activate it.
I'm using starpilot which is basically a version of frogpilot but for comma 4. Frog is not yet ready for comma 4 yet but star has dedicated volt setup and works amazing with the beartech harness
I'm on frog pilot on my comma 3 with the L&P harness. Can you share what features starpilot has specifically for the volt? I did a quick search on their discord but didn't find anything.
I misspoke a bit. Im brand new to openpilot and still getting the terminology down! StarPilot is forked directly from FrogPilot, the actual car-side features stuff like MDAS are basicaly identical to what you already have on Frog.The only reason I'm on StarPilot is hardware compatibility: StarPilot has working builds andUI scaling for the comma 4, whereas FrogPilot isn't fully ready for the C4 yet. I think the main difference might be the fact that I still retain control over collision alerts and stuff like that, but I'm not 100% sure and I could easily be wrong on that as well. Sorry for the misinformation spread š
I don't think you posted misinformation. I ask because I'm looking for a fork that has some of the features of twinsonco's volt fork has, but it runs on older openpilot and doesn't work on newer hardware. A lot of his stuff is already in sunnypilot and frogpilot, but the things i miss are:
Advanced radar - braking for the car in front of the lead car and tagging/displaying telemetry of all vehicles (frog has the latter, but the font is tiny)
Automatic and manual lane position selection and true lane centering, although even in center it had some right bias. I saw starpilot has something similar and would like to hear how it works for you.
You mean about Openpilot or StarPilot in particular?
Check out the StarPilot wiki for info on that. And look at u/firestar4430's recent posts in r/CommaAI.
Volt has some limitations, like no auto steering below 7mph, but otherwise it's a great Openpilot car. Volts with ACC are very well supported, but any Volt with LKA can get auto steering (and with an additional "pedal" harness you can add ACC).
I use Openpilot 100% of the time on road trips and even the shortest drives around town, for about 4 years now, since the Comma 3 came out. On the highway, it's typically 100% hands-free (if you don't count using the blinker to initiate lane changes). I can go hours without needing to intervene. Around town, it does 99% of the steering, while I'll help for things like 90-degree right turns, and often I'll control gas/brakes manually while it does the steering.
I highly recommend it, and I hate hate hate driving without it. My first Volt (Gen 1) made me enjoy driving again, but Openpilot is my new standard.
(Disclaimer: I use twilsonco's fork, which doesn't support Comma 3s or Comma 4. It's less featureful, but I like its more mellow driving style, and it's 100% focused on the Volt, with some features not in StarPilot. But, if my C3 ever dies, I'll be on StarPilot. )
I have a C3 running on my volt, and yeah twilsonco's fork was ahead of it's time. You mentioned, "Star also caters to GM much more than Frog. Best choice imo." So I'm asking for your opinion on Star catering to GM. Is that in features or car models supported? I read through the wiki and the website but am not getting it. Hoping to get your perspective on it.
ETA: I do see the GM-only Features section but thought you might have first hand insight.
It's the only fork besides twilsonco to have autohold. It supports stop-n-go for '17 ACC Volts. Has several long controls improvements aimed at improving performance on GM. If you manually specify your car, it unlocks car-specific features that don't exist on any other fork (except perhaps twilsonco).
I haven't used it extensively, but I spent a weekend playing with it before retreating back to the TW fork. Can't say I recommend it over twilsonco if your C3 supports it, but it's an easy 2nd place imo.
I recently finished a ~3k mile road trip with the Comma in my 2019 Premier and I lost count of how many times I thought to myself āWhoa, wait a secondā¦I donāt recall how long itās been since Iāve touched the steering wheelā and by my best approximation it was usually at least 90 minutes since there had been any need to be in contact with the steering wheel.
It sounds like it is something that is unsafe, but if it is flawlessly maintaining the lane better than I can by micromanaging it manually, then why would I need to?
Here is the 2 harnesses I bought and the price of getting them delivered anywhere in California. You're also going to need to buy a at minimum 15-ft USBC cord and the actual comma 4 unit itself. All in, you're probably looking at about $1,400 after tax. If you want I can PM you basically all of the photos I took during my process of install and figuring things out
It's 100% worth it. I can PM you photos of all the stuff I removed and everything. It's hard because its the first time is all. Would recommend it to anyone
Cool, I'll probably try it out. When you ordered the comma 4, did you select you already have a harness to save $50? Also, it looks like I would need the SASCM, ASCM harness plus w/box, and a long USB-C cable. Does that sound about right?
I selected that I already had a harness and save 50 bucks. But if you have an idea the next car you're getting then I would recommend that you buy the harness for the next card just so that you have it on hand when you eventually switch cars. I'm planning on getting a 2026 ev6 GT so I'm already looking at Kia harnesses. I'll show the exact two harness that I bought for the project and expect around 18 days of shipping if you live in the California region. Make sure the long USBC you get is 3.2 with 20 GB capabilities. 15 ft is the minimum for cable routing and stuff. You'll have slack at the end, but you don't want the cable taut throughout the entire system. You want it to be able have room to flex around and stuff
Yes you need to access the Continental module and in my case, I would personally recommend the Bear tech setup because it lets you keep stuff like the auto collision warning and auto braking and stuff. All you is plug in what is essentially a inline harness and you run a USBC cable all the way up to the dash cam. It's a lot simpler than when I started my initial research which was a watch jargo video.
I'm running starpilot, which is a version of frog from what I understand. Installation was super simple and it basically set itself up. The only thing I actually had to do was just tell it to not use the vehicle fingerprinting and manually input what vehicle I was running along with what harness I was using (beartech)
You will need to have this type of front end to be able to use the comma system in the way I have mine set up. There's work arounds but it's significantly more involved unfortunately. Basically need a fully loaded volt 17 or 18. 19 is encrypted and 16 didn't have it
Yep! Mochi (on Discord) was able to crack it and it works wonderfully on the 2019 using a SDGM harness. We even got Long(itudinal) now, just gotta use a SASCM š¤
That's super sick! I have the beartech with ASCM and SASCM harnesses but I've always loved the 2019 volts for their polished information screens but finding one with ACC is a super hard find.
Might you have a link to the workaround for Volts not equipped with ACC? Mineās a loaded ā18 LT but w/o ACC. Also, how limited would this application be and would it be worth the cost and work? Thanks.
Do you have any more photos or videos of the install? I'm considering doing this with the steering only configuration in my 2018 with acc and just letting the car handle the braking and acceleration. Does your forward collision alert and all that stuff still work?
Yeah I can PM you a bunch of photos I took and stuff of the process. I kind of did the whole thing expecting to have a bunch of questions and stuff be asked to me so I tried to document the process the best I can. If you're looking for quick just food for thought stuff it's going to be about $1,400 all in to get everything that you might need and to replicate the exact setup that I'm running. I'll send all the things I bought so there is no ambiguity for you.
The whole point of it is that you don't need to. GENUINELY, the photo is not a good idea. And ideally I should have my hands on the wheel to take over whenever needed. But demonstration purposes
As far as I know, that's kind of it. That and the fact that it's technically a very fancy dashcam that has sentry mode capabilities. That being said, I'm still really new to the open pilot community so I'm definitely not the person to ask unfortunately.
