Comma.ai

I only tried Sunnypilot test-c3.
I changed lane change blinker thing to 2 seconds, laneless. I don't think I changed anything else in the settings.
I did also have it download the maps, which I think only matter to show the speed limit, which doesn't matter because my truck already shows it and there is no navigation on the Comma for my truck.

Do I just give it the URL of https://openpilot.comma.ai after resetting it?
I see instructions on how to change via SSH but I don't really recognize the commands to bother going that route. I'm not familiar with Github until now.


Which one? The "Ram OpenPilot Community" or the Sunnyhaibin one?

That is the stock op. Are you on discord?
 
On the RAM discord the link for RAM 1500 realfast is pinned in the pinned massages' Just type in realfast in the search engine
 
I have been using Sunny's test build for months and love it. I disagree with the idea that laneless is the best - I keep it on auto most of the time. I only force laneless when on roads with poor lane markings, or if using in inclement weather that is reducing vis/covering the lines. If the road has good markings, using auto/forcing lanelines model generally holds better within the lane IMO, especially in city driving. Lanelines also helps avoid driving in the middle of a narrow roadway as long as it has good lane markers - some of the rural roads on my commute are fairly narrow, and the laneless model will ride the middle of the road... but lanelines will stay in its lane.

I agree it has a lot of shortcomings as a dash cam. I have seen screenshots from at least one fork that overlays pertinent driving data onto the video output, so it is possible. Quality is decent, but it really stands out in terms of dynamic range and low light/night clarity. The windshield glare can be annoying, but I haven't noticed any issues as a result of it.

Agree. I use auto almost exclusively.

Hard to tell from the photos. I didn't see anything wrong. On the full stop, when did it start to go into the other lane? It stops steering around 6 to 8 mph. That's a limit of the truck's EPS firmware. Same for the loss of torque on some curves. It's not a Comma problem, it's a Ram problem.

I don't understand how that can be. My truck has the Auto Parking feature, which lets it turn the steering wheel even at 0 MPH, in order to park the truck while I operate gas, brakes, and gear selector.

I think any RAM that is supported by OP has the same feature.

So, the truck clearly CAN control steering at speeds below 6 to 8. In other words, it sounds like a Comma/OP problem, to me.

No, it is a limit in the EPS firmware. The EPS firmware will fault if we try to apply too much torque. But we can only apply any torque over 32 mph. This is because LKAS doesn't activate until over 32 MPH. We then set a bit in OP that tells the truck LKAS is active which then allows us to continue to steer under 32. Auto park is only available on trucks with that. It is controlled in the parktronics module. When I added it to my truck, I had to replace it with the correct module. The only way we could activate full torque would be to fool the truck into thinking it is in autopark mode. That isn't really an option as comma has said that is a safety issue.

And there you go. It's not a truck issue. It *could* be done. It's a Comma/OP issue.

A minor and pedantic point. Please ignore me. I'll show myself out.

Well, I said could. There is no guarantee that even doing that would work.
 
I guess I will have to run back down to Darksteel's place and try my Comma3 on his truck and his on mine.
I do have a spare USB3 cable in case that has a problem too.

Haha.
I was just thinking of messaging you and seeing what settings you had configured for Sunnypilot (I think you were using test-c3?)
The realfast beta2 is working well for me. I haven't had a ton of time yet but i'm happy with it so far. I do with I had settings to make the device turn off quicker then whatever the default time is.
Not a single crash running the realfast build so far.
 
Sunny's has all of Realfast incorporated in it with the Nov test-c3 Build. I have not tried the Mid December release yet as it is not as stable per Sunny.

I have seen where sunny has said that, but the 20221216 build has been completely stable for me. I’ve not had a single problem, and I find that the steering/centering is improved as compared to the previous (test-c3) build.

Also, my truck steers all the way to 0.

You have the special EPS firmware. It's funny that Ram has different firmware that allows true steer to 0 on some Rams.

Yeah that’s wild. Did that start in 2022? Or does it have to do with having the self parking feature? Which I have.

Nope, there is no reason for it. We have some 2019s that have it too.
 
I have a 2021 Laramie with a Good EPS Firmware. I was one of the first to test for Steer to Zero.
It worked fine all the way to work, but failed with errors on the way home. With some subsequent
Testing we found the Reverse Bug that caused the error.

I will try the December build by this weekend.

Thanks for that explanation. When I initially installed openpilot and mounted the unit on the windshield, I plugged it in and took off for a test drive with the wires dangling and the cover laying on the seat beside me.
I immediately initiated ACC while still on neighborhood streets and driving around 30-35 mph. When I got on the freeway it acted erratically or not at all. I was ready to return it for a refund. But after taking a deep breath and reading this thread I started over... took it inside, connected it a charger, Reset it and installed sunnypilot. Went back out and took it for another drive and waited to initiate ACC until I was on a highway with good lane markings going a steady 55mph. It's worked "perfectly" ever sense. By "perfectly" I mean "has met or exceeded my expectations."

My previous experience with lane keep assist is in a 2017 Audi with that feature, "stop & go," and "traffic jam assist." The Audi is a pleasure to drive in all aspects and it's "Driver's Assistance" is a huge help, especially on long trips. So much so that I was experiencing serious buyer's remorse when the RAM system proved so ineffectual in the 2019 Limited I recently purchased.

But with the Comma3 working this well it's actually markedly superior to the Audi.
  1. Comma "sees" the road more clearly and almost instantaneously in almost all reasonable conditions. The Audi sometimes takes a long while to see the lane markings and easily loses them, sometimes for no perceivable reason. The Audi is no help at all on roads without clear lane markings: with faded yellow lines on your left or on two lane roads with no white stripe on the right it can be more harmful than helpful.
  2. Comma doesn't annoy you with constant beeping to put your hands on the wheel. Even with your hands on the wheel, the Audi beeps on any straight road unless you jiggle the wheel within 15 seconds. It beeps so often you're tempted to ignore it.
  3. Comma doesn't "fight" you for control or make quick, unpredictable steering adjustments. The Audi often tries to take an exit and on rare occasions will swerve unexpectedly. For example, this morning there were light sprinkles that were causing distortions through the windshield. I was passing a truck in narrowed lanes when the Audi suddenly jerked to the right. Fortunately, I was anticipating that could happen and had my hands firmly on the wheel. I should have turned it off.
I suspect the Comma's advantages stem from the fact it "sees" the lanes and tries to steer down the lane, while the Audi only sees lines and tries to steer between them. I don't have enough experience with how the Comma deals with stop and go traffic jams to compare the Audi, but in limited experience it seems promising.

I use comma in traffic with stop and go, and it works surprisingly well. It does have a lag before going when traffic starts to move, so I usually use the gas to get going. Otherwise, if I wait for the truck to go there is more space than I like, and the person behind me probably thinks I'm daydreaming.
One thing I really like about SunnyPilot is the mute function.
Enjoy, and be safe.
