How is your LKAS (Lane Keep Assist System) performance?

[MIGULZZ]

oh yea also keep in mind if any of you are lowered that can also change the way it reads the lanes, it so hard when I have to tell customers we can only recaibrate oem spec cars...

No issues with my LKAS - Dead center on highway straight roads with small bends. Setting it to active in the settings ensures it's always trying to steer to keep center - versus the normal setting. Find it also works really well on city roads for 35-50mph. Can get in the way with curvy/fun driving, but that's what the button to disable it is for.

If you keep getting the warnings just apply some steering input. It's not about having your hands on the wheel but the electronic steering seeing some input from the driver.

I've tested many vehicles including Tesla with partial autonomous features like LKAS.
hands on detection on Stinger is actually quite good compared to what are out there in the current market.
Most cars there are out there needs to see some sort of torque from driver for vehicle to determine driver has their hands on the wheel.
I've only seen one vehicle from Cadillac that actually detects your skin making contact with steering wheel without having to input some torque to the steering wheel. .

Good to know. I still won’t use it though. Why does it tell me to pay attention (or take a break) when I already AM paying attention?

There is an attentive meter somewhere in the dash menu. I believe if the LKAS detects/warns you multiple times about the steering wheel it may assume you attentiveness is low. You should be able to turn it's sensitivity lower though in the settings. Also, have the option to turn it off I believe so it never bothers you about taking a break.

Initially, it took me about 1,000 miles to get used to the nudging by the steering wheel. It feels exactly like some POS with loose worn steering that is trying to wander and millions of miles have developed an instinct to push back against it. After about 1,000 miles I adjusted to just let it have its own way and we're doing okay now. However I do dislike it trying to take every off ramp when the right line curves away, but when the line is back 75 - 100 feet down the road, it centers up again.

In the beginning, the 'keep hands on the wheel', 'driver's hands not detected', 'lane keeping assist disabled', about every 4 miles even with both hands firmly gripping the wheel, seemed rather insulting. But I decided if I let a car piss me off, it was my problem, not the car's. So now I just ignore that crap and really enjoy driving the car.

Still good to know. The on/off button works well enough for me.

I keep mine off. i have had it in most of my cars, they are totally useless IMHO, the worst ones couldnt even steer up a few degrees curve in the road without me going into the next lane.
The same with attentiveness thing, if i am going in a straight line and the car aligns it self to go perfectly for maaaany kilometers, why should i have to jerk around the steering wheel like i was chocking the rooster?

 

[Dodger Blue]

I only use it sparingly. The warnings to keep my hands on the wheel (even when they're there) are a bit annoying and I don't feel like I should have to induce some unnecessary input just to satisfy the computer. It defeats the purpose, if you ask me. But it's good to know that this is "working as intended" and not a software bug, I guess...

 

[Cyrus Duong]

I use it more like an assist to keep me centered instead of relying on it to steer completely like autopilot. While it is capable its meant to help you in case you get distracted looking at something on the side of the road or reading road signs. It is a little bothersome how it tugs back, but as long as you are actively steering as you would normally, it should never have to warn you. It detects based on driver giving input (maybe not enough to steer the car) like a thumb on one side or the other. From what I can tell.

If you want it to do it without input then you should look into getting something like comma.ai
I've thought about it myself - It can even act as a dashcam AFAIK. But I just haven't had the time to look into what it would require. Maybe if there is enough interest for our cars I can try to figure it out and do a write-up... But I think our LKAS is sufficient for the common people.

Disclaimer - You, the driver should always be paying attention to the actions on the road and be ready to react accordingly. I do not have any experience in the use or functionality with comma.ai openpilot and am not held responsible for my recommendation. Do the research and understand the what is involved.

It's one of the best in the industry outside of Tesla so there's that. In general the amount of time you can go without putting your hands on the wheel is correlated with how much money you spend on the car. The stingers is pretty good.
That said the Telluride one is the better version, I assume it's the one the k900 has and it is probably the best drive assist suite outside of Tesla. There is a night and day difference between the two systems in my opinion.
For the stinger I really only use the system on the highway to keep me in lane when I have to poke at the tablet on my dashboard. It's been especially useful when I've had to join conference calls while on the road.

Everyone says Telluride has better version.
does anyone know if Telluride has better Camera for lane detection or just better logic?
If it is just better logic, I hope that better version can be apply to our Stingers with simple SW update.

 

[Cyrus Duong]

My hunch is its software. They have the ability to follow cars in front of you (cruise follow). AFAIK. But doubt it'll be pushed into stingers as they probably have a validation/safety process they have to follow for each vehicle. Probably don't want to take the risk of trying to make something work that hasn't been validated or developed for our car... At least as a software engineer that's my viewpoint.

 

[Ucinn]

I can't answer why it's better, my hypothesis is that with it being much higher off the ground, it can see the lines on the road better. I'm sure the software is different since it lets you keep your hands off the wheel for a longer period, but that could be the only change..just don't know.

It's more than just software as far as I can tell. The driver assistance suite has some integration with the GPS. Its command flow is a little different too. Basically without adaptive cruise control on, the LKA is essentially the same system as the Stingers, it will keep you in the lane but will bother you much more frequently if it doesnt detect steering input. When adaptive cruise is on it appears to also activate an enhanced version of the LKA. It will auto adjust cruise speed based on the speed limit of the highway your are driving on and certain interstates will allow the car to drive itself for miles before it warns you to put your hands on the wheel.

 

[Ucinn]

That's called the highway drivers assist (HDA) which is completely useless if you ask me. It's supposed to change your speed on a federal highway to the speed limit it has on the GPS unit. You have to set your cruise at the exact speed of the road you're on or it won't work. Once active, then it will change it. Problem is, around here more times than not, that speed displayed on the GPS is wrong. It also doesn't take in to consideration construction areas. I don't know of anybody who wants to go the posted speed limit anyway. I don't use it.. I just used the smart cruise control (SCC) and Lane Keep Assist(LKA) on the way home and the LKA is better at staying center lane and in curves than the Stinger is using just those two features. It also wouldn't bug me as much to put my hands on the wheel using just those two features.

I'm just saying that if the GPS recognizes you are on one of those highways, then you can rely on the LKA for longer than you otherwise would.

 

[Ucinn]

The LKA uses the same system, a camera mounted on the windshield, The SCC uses the same radar plate in front. the GPS is only used when you use the HDA which is just for setting your speed.

I tried mine a few times on not-so-perfect quebec roads. It worked half of the time that it was supposed to work. Some corners I could let the car drive itself and turn autonomously (with my hands lightly on the steering wheel). Some other corners, it only beeped when it crossed the white line on the right side of the road.

It doesn't seem to detect the yellow center line, or at least it never corrected me when I went over it (only beeped, so it does detect it somehow). Tried playing though "normal" and "full" LKA setting.
