2025 RAM Lane Centering

[firecadet613]

You cannot hack the systems on a 19-24. You can add a device called a Comma to it, but it is far from a hack. And it works way better than Super Cruise or Blue Cruise and better than the new factory Ram system.

And the new factory system on the 25+ system works the same or very similar to Super Cruise and Blue Cruise. It may not have all the features, but it is NOT lane keep assist (LKAS) that we have now on 19-24.

Good to know, thanks!

Blue Cruise gets great reviews -- but Ford is kind of proud of it. Hardware is on all vehicles (that can be supported) and software is enabled by subscription. That's tempting because most of my driving is local, but we sometimes travel with grand kids or pull a pop-up and I could enable it per month. Ford (and GM) have a lot better road coverage than RAM, and I haven't found anything about plans for RAM to cover more. I really don't understand why only mapped roads are supported. There will always be road construction that shifts a lane -- does it just give up, or does it follow the lines? And when lines are available, why the need for the map? I'm even OK with being responsible for decreasing speed on tighter curves, but a "good" vision system could look ahead at lane markings and calculate whether there is sufficient torque available to make the turn, or if the cruise speed is safe for the turn.

I like the idea of lane centering even for local driving. When my wife needs to get something or even pick up a cup, it seems like she takes her eyes off the road too long and sometimes does drift in the lane. From the owners manual and one response, it does seem that web sites got it wrong, and lane centering simply watches for lane lines or something that it can interpret as lines. Just like the Tucson.

The mapping is (my understanding) due to the road curves, etc. I used Super Cruise on a rental out in Yellowstone and it was impressive (and nerve racking) to see it slow to 57 or so on some tight turns on a 70mph two lane...

It was neat and fun to try on a rental, not sure how much I'd use it on my daily driver, though I've come to appreciate the adaptive cruise (which I wasn't a fan of the first time I experience it on a Nissan rental)...

Mine has "White Knuckle Cruise" for freeway driving. As long as I am paying attention it does a really good job.

Wife‘s Grand Cherokee Overland has the assist. It works very well in conjunction with adaptive cruise, but the trick is learning where the pressure spots on the wheel are. I can rest one or two fingers on the wheel, it works. Remove hands or don’t hit the right spots on the wheel, it’ll bark at you.

Driving up north for hours, it’s a nice break.

Sounds similar to my wife’s system. Hers also has bird assist.

I looked there... and really dislike Discord!

Yes, it really sucks for getting/giving product support. A threaded forum (like, for example, this one that we're on) makes it a LOT easier to have focused conversations and for later people to find the info that was provided in those older conversations.

Comma customer service gave some suggestions that didn't work. I cleared and reinstalled OpenPilot, which included OS re-install. Didn't help. Instructions to re-flash from Windows didn't even work so perhaps there was a device problem. Plugging in OBD sent a signal to the Comma so at least some of that was fine. Best guess is defective Y harness. But my background is software and not hardware, so that's just a guess. It did a GREAT job tracking lane lines (marking them with green) plus road edge (in red). On multi-lane it would stay closer to the right edge of the right lane, but perfectly centered in left or center on I-75. It tended to hug the inside of turns a bit, and lane change was more abrupt than it should be. I was using SunnyPilot on the Tucson. FrogPilot seemed like the focus was on gimmicks, and the frog "croak" was just plain dumb! Open Source is great if the best of the forks are merged back to the base, but it seems like Comma needed a strong software product manager. Get lane centering PERFECT before going after E2E navigation. But I understand that's a lot more fun!

Thanks again for your help. I still haven't decided on the upgrade and am slightly tempted to wait for RAMCharger -- but expect at least $15K more and I can't really say I need it.

I upgraded from a Comma 2 to a 3X last Fall and have been running SunnyPilot in my '21 1500 since then. It definitely DID have a problem (for me, anyway) of cutting too far to the inside on curves. But, the latest release (in the last month or two, IIRC) has made it a TON better. I only very rarely have to intervene on curves anymore.

I am waiting on the 2nd or 3rd year of the RamCharger for my next truck. It will be interesting to see how the factory ADAS in that compares to running OP/SP in my current truck.... It would be nice to no longer need a Comma, but I am very skeptical that RAM will even equal what OP does, much less exceed it.

Hearing that the current ADAS offering for the '25s actually requires you to put a hand on the wheel regularly is a clue to me, right there, that I will be hoping for OP to be available for the RamCharger by the time I buy one. I do road trips in the 300 - 500 mile range on a regular basis. Getting on the Interstate in my current truck and not having to touch the steering wheel for hours at a time is really nice!
