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!

I'm considering upgrading from 2019 Laramie. Most online info says lane centering is on "approved" highways but the owners manual says marked roads. Which is correct? Also, does "hands on the wheel" really mean steering input (like on my 2019) or do they now use a touch sensor? And if so, is it both hands as implied by documentation? I drive our Tucson with one hand on the bottom and try to remember to put a bit of pressure on the steering wheel before the warning is displayed. (Can be up to 2 minutes of hands free driving....)

Is the lane centering near perfect? Or does it hug corners, ping pong, drive toward one side of the lane, drift across the lane marker, etc? Getting it right should be fairly easy software.

Hello Knelso4. I just purchased a 2025 1500 bighorn with pkg2 (big screen, upgraded stereo) I have never been in a newer vehicle with a more garbage lane keep system. I understand that it is not a hands free system, but this thing will float you over to one side of the road to the other and yes, like a ping pong throw you back into the lane. At highway speeds and set to heavy it is down right dangerous. My wife had a Hyundai Santa Cruz and now has a Hyundai Sonata. When that system is activated, it will keep you centered in the road. If a curve is coming, it will keep you in the cente of the lane and turn the car. My 2025 1500 will never keep the vehicle in the middle of the road and when it corrects itself, it will throw you in the lane to (if your lucky) bounce you off the other side of the road. It seems to do better seeing the white line on the passenger side, but good luck on the middle line. I LOVE my new truck, but HATE the lane keep. If someone in the forum can tell me it is not supposed to act the way it does and I should have it looked at that would be wonderful, but until then, it is dangerous.

It's not dangerous because you are using it wrong. It's not a lane centering system. It's designed to keep you from crossing the lanes or going off road. It pushes you back from the line. You can adjust the torque it applies. If it jerks your truck, then it is broken. But from mine and most people's experience, it doesn't if you have your hands on the wheel.

Vincent nailed it. It’s called Lane Keep Assist.
My wife’s GC has the ability to keep you centered in a lane, but you still must have a hand on the wheel (or as I’ve found out, at least 2-3 fingers pressure).

You’re asking it to do what it’s not designed to.. it’s assist. You’ll note if you go to change lanes without a turn signal, you’ll feel it nudge you as well. But in no fashion is it meant to keep you centered. For me, it’s more of a nanny to remind me to use turn signals.

I think in my wife’s GC it’s called Active Driving Center Assist or something like that.
