Comma AI self driver assistant

Flipping it worked! Manually selected in Sunnylink.
Says sensors calibrating

edit: working! Just did a drive and it’s fine.
Thanks for all the help @Ajzride and @UncleTony

Resurfacing this since a few people have reached out — this seems more common on 2024s.


Some users are seeing AC not working when the comma is installed.


This has been traced back to OBD power being in use. This has been resolved by replacing the long USB C cable, but the correlation isn’t fully understood yet.


Steps to try:

1. Rotate the connections on both sides of the lightning coupler
2. Make sure everything is fully seated

If that doesn’t resolve it:

• Replace the comma-supplied OBD-C cable with a 10ft USB-C (3.2 Gen 2x2) cable
  
  
  I would suggest getting the replacement cable from amazon and testing with it prior to installing it under the panels in case the issue still exists and at that point I can send you a new coupler and the cable can be returned to amazon.

@UncleTony I saw you recommended FoF Liquid Crystal on Discord.

Any chance there's explanations about Liquid Crystal vs WD40 vs Notre Dame?

I haven't done any highway testing yet, but was thinking about what I should be looking for - I was also interested in all the new world model stuff.

I preferred FoF liquid crystal when I had my lightning. I know a lot of people prefer WD40 and Notre dame as well. It really just depends on what you like and the way the truck performs with the model.

Enhanced my Google Fu and found this for future people wondering about models and "what you should run"

Thousands of people don't even select!

Model selection is the biggest point of contention across the entire community. Being on a torque based vehicle now, I have just stayed on the default model and it’s been fine for me.

If you're like me wondering what "Default (Did not use model selector)" is - you can check the repo:

It's `CD210` today

It’s not really a power problem. The OBD power comma uses also has can in it and it adds a resistance to the setup from the OBD port. I would try unplugging it and see what it does. The comma will just take a little bit longer to boot. If that fixes the issue, I can suggest a new long cable

Thanks for redirecting me in the right direction. I was able to resolve this issue.

I initially tried unplugged the OBD cable from the harness but was seeing the same A/C issue.

Then I just swapped out the USB long cable with another (shorter) one that I had at home. Everything seems to be working as expected now!

First, I want to thank everyone who has made this community an awesome experience to be a part of. There has been an amazing amount of collaboration and positive feedback for the entire BluePilot team. As we reach the two-year anniversary of the launch for BluePilot, I am taking a moment to let the community know that I am shifting my priorities now that BluePilot 6.0 has been released. I never had a desire to lead my own fork; the whole project started because I was passionate about improving how openpilot behaved on Ford vehicles. After I developed several key improvements, but my PRs were rejected or ignored by Comma and the popular forks, and since I felt guilty about how much better my experience was than everyone else driving a Ford, I started BluePilot. While I have learned a lot from leading this project, it is not the type of activity that I enjoy. The grind of keeping up with the changes forced on forks from Comma has left me with no time to pursue the aspects of the project I do enjoy. I have been unable to make any progress on better lateral control, firmware unlocks (I bought a spare PSCM over a year ago and have not had an opportunity to work with it), and new vehicle ports (Big Bronco anyone?). Now that bluepilot is in a very stable state, I will shift my focus back to the efforts I believe will have a greater long-term impact on the community. My reduced online presence will require other members of the community who have benefited from the last two years of work to give back by helping new users get started in the ecosystem. @tonesto7 will be continuing to support the project, ensuring the platform can remain current by incorporating upstream changes and supporting compatibility going forward. I am also seeking individuals who would be willing to take on a role of interfacing with the community for bluepilot, soliciting feedback on new and future features, testing, and developing the future branches. If you are interested in taking up this mantle, please reach out to me via a direct message.

Now you just need to buy a rivian and come help me with my lateral issues

Happy to help where I can with community questions.

I tried LCD, didn’t love how it felt in curves.

tried the reverse drive (return) in the default model (cd210). Only issue I’m encountering is sporadic right curves hugging the right side.

otherwise I’m enjoying default settings with default.

EDIT:

Going to change one setting with Custom Tuning:

BluePilot: Low Curvature PID Gain = 3.05

I didn't really notice much ping pong, so I think it's mostly about holding center.

UPDATE:

tried default (cd210) and LCD and tried tuning. Couldn’t stop the lane hugging. Lane hugging was even worse with LCD.

Setup the recommended WD40 (Advanced lane position, -0.05 lane offset and default tune)

will try again tomorrow!

MAJOR UPDATE BELOW:

ultimately ended up on wd40 with the recommended settings (my lane offset is -0.10 probably bc of local uniqueness)

 

[BluesClues]

Is recalibration recommended after changing models?

just did a drive to airport but will push lane adjustment more. Was consistently to the right side.

I have always recalibrated when I changed models. I don't know if it's recommended or not.

 

[KingStraasha]

Yes, recalibrate after each model change so that it will begin learning about your vehicle.

@BluesClues I have been toying with the POP models. I didn't like POP V2 but I do like POP v1. I am using these settings with good success. I feel like it stays centered while going straight but it goes slightly towards the inner line during curves (this is most likely the model):

Use Custom Tuning Profile: True
Predicted Curvature Blend Ratio Low: 0.30
Predicted Curvature Blend Ratio High: 0.30
Enable Advanced Lane Positioning: True
Enable Lanefull Mode: True
Custom In-Lane Offset: -0.0
Low Curvature PID Gain: 2.0

I am not sure how they will work with WD40 though.
