Comma AI self driver assistant

[watts/up]

I'm going to add onto this question and ask: Has anyone noticed any beneficial or adverse affects to efficiency when using Comma? I don't want to start a whole 1PD vs 2PD debate, but I'm just curious if there could be any attributable changes because of it...

BluePilot is just sunnypilot with a bunch of Ford specific patches applied.

comma got rid of connected navigation because it never worked. They are supposed to rewrite it in 2025 And put it back out there.

basically it behaves like BlueCruise (hands free lane centering) but on any road, not just mapped interstates.

Does it stop and go at stop lights and stop signs? I’ve seen different videos. Sorry just questions that keep coming up.

I don’t think 1PD will work when you engage Comma ACC. The regen confuses it and cancels ACC. I think Isaac has it on his to-do list.

Yes, but that is very beta and only works about half the time.

Well I’m going in! Just ordered the comma. Saw the sale where the car harness is free and that was enough for me. So now I impatiently wait.

I should be getting it tomorrow. Im assuming from the videos I’ve seen I will install openpilot then go back and install blue pilot? Can you give me the link for that or point me in the direction of where to go to make sure I do the install correctly. I’m pretty comfortable with tech but want to make sure I do everything right. Thanks!

You can install BluePilot first. Just be sure to go into the menu and set your tuning profile to low, or turn off advanced lateral control.

1 Pedal works fine with Comma ( what i mean is it is seamless. You dont notice when you turn on or off. And when you have mads on you can drive one pedal with steering controlled by Comma.)

You are using Ford ACC not OP ACC though. If you turn on OP ACC and Experimental mode, I think 1 pedal gets broke.

Thanks, had to look up MADS. I think I may have made my question more complicated than it needed to be by mentioning 1PD/2PD. Really I'm just curious about efficiency overall: I'm guessing efficiency shouldn't be affected much, if at all, if the truck is still using regenerative rather than friction for the bulk of its breaking. I was wondering if the software would be more aggressive than me in acceleration and/or harder when breaking. Again, probably over-thinking this.

The acceleration profile is tunable, there are 4 levels of aggressivness.

This is correct. The OP ACC seems to recognize the regen/braking on 1PD and disables the ACC.

Ok, for those that are ordering new kits..

Comma sends you all you need now for the F-150 platform. They now include the long USB C cable with a USB C to USB C connector and the 90 degree standard cable. I taped my connectors with Electrical tape because I was thinking it would end up under the headliner. Now that it is installed, it sits right next to the rearview mirror casing. Leaving the tape as of now because the adapter is silver and it looks better black.

If you want to use Blue Pilot, it seems you will have to use the link @Ajzride posted for staging

installer.comma.ai/bluepilotdev/staging-2.1

otherwise you get stuck on the registration.

Blue pilot is way better than (Base) sunnyride after about a 20 mile comparison on each.



Personally I am going to leave the stock harness on my setup for the time being due to the startup errors being pretty minimal and the fact that I almost always remote start the truck.

1000% times better than blue cruise.

Edit to Add: Ferrites won't do anything to resolve the issue, in my case, I had no errors until I plugged in the USB C and comma unit.

I have been through the 18 pages (and growing) of this thread a few times and I'm still trying to wrap my head around what is actually needed for this harness. I am going to order a Comma once I get this all figured out so I can use the 30-day trial period to make sure it works on my 2024 Pro to which I added ACC/LKA as outlined on the forum (a 42 page thread, so this one is still easier to work through). @Ajzride told me it's "likely" that Comma will work for me.

-Regardless of if I get the v1 or v2 harness from Comma, will I still need to add an extension or extend the stock harness, as well as add some resistors to certain wires?

-Is @Drayday55 or @Ajzride still making extensions as a side hustle? Do I need to see if I get a v1 or v2 harness first before seeking out an extension? I assume I have to receive my harness first and then send it to them to modify?

-If I just use an unmodified stock harness and everything that comes in the Comma box, can I just plug in the Comma or turn it on after I have started the truck to avoid errors? Is this a practical solution? Are the errors on the truck or on the Comma? I don't have a Comma yet to see for myself if this solution would work.

Thanks in advance for any answers or advice.

You can just order the Q4 Ford harness with your unit and you will get everything you need to install. If you want to get your harness modified, you can have it sent to someone that will do the modifications (Either ship the harness directly to them or send it to them once you get it).

The canbus errors are an issue with the lightning. It's not a huge deal if you park inside, and remote start. But mine has been crashing running blue pilot randomly during drives which causes the canbus network to throw a bunch of errors while driving. (None of them really effect the base functions of the truck, but you lose a lot of the stock assist features).

I am working on a PCB to replace the female to female adapter they send you to connect the long and short USB C cable, as I've successfully added resistors to the USB C cable and resolved the canbus errors.

I really have no idea what will happen once I have the PCB completed as I plan on turning it into Comma to see if they will accept it as a resolution and start shipping it with the kits.

The canbus errors will come regardless if you plug it in before or after you start the truck as it will error out with the USB C cable plugged into the harness until open pilot is fully booted up and sending its own signal.

We are working on an update for BluePilot to be compatible with the newer comma devices shipping. We have no idea what comma changes, they have no documented updates. But something clearly doesn’t like the older software BluePilot is based on. The problem is that we are built on SunnyPilot, and he hasn’t updated yet either, so a lot of features are going to be missing from this release.
