Adaptive Cruise Control Feedback

[Anton]

a few things...


The lane centering and lane position thing absolutely works and if you slightly hold the wheel to push it in the lane you can feel the steering adjust to this new position. it feels like there are only like 8 positions the car can be in and when you get to one you will feel it click in.


ACC does fantastic as long as it knows there is a car ahead. The issue with it braking late seems to me entirely limited by its ability to recognize the car ahead. If you are following close to the car it will slow down smoothly, still a bit slower than I prefer but it does it fine. BUT, and a big BUT. ACC is affected by not only the follow distance you set but which drive mode you are in. I think they only tuned it for engage mode, as both whisper and unbridled perform terribly. whisper always brakes late and often causes the crash alert to chime. unbridled brakes too hard and undershoot its target causing it to brake, let go, brake, let go.

one pedal mode does nothing in cruise control. you can actually see the car disable 1pd when you turn on cruise control. I like to drive with 1pd on because if a car is too far ahead for the car to tell its stopped i can just pause cruise control, let 1pd start slowing me down and then re-engage the cruise control and most of the time it immediately realizes the car is stopped and do its thing.

No. Lane centering does not work for me like you described. I've tried fighting the wheel and holding it on one side for upwards of 15 seconds. As soon as I release it goes back to "drink driving correcting" and going back to what it thinks is the center. For me, I really think there's only one position that the car will center to and doesn't listen to any user input as preference. 8 positions??? What do you mean? 8 positions within the lane? The steering wheel always fights me and never adjusts.

ACC starts slowing down wayyy too late when there is a car stopped ahead that you did not follow... I've tested it once and it felt very uncomfortable for it to start breaking so late. I'm probably not going to test it again... otherwise ACC is fine.

I don't know if its actually 8 positions but when you are trying to push it from center you can feel the wheel relax its centering in steps. It makes it feel like there are a number of sub-lanes that the car will track to. It generally won't let me set a position where you would be on top of the lane but i can absolutely move the car's tracking position closer to the center line or closer to the outer line. but as its mentioned in the manual it forgets that as soon as you or it 'cancels' lane following.

ACC isn't meant for bringing the car to a stop with a car just sitting there. The radar + camera has to understand that the not moving object is a car and its infact in the lane. Its slow for sure but you shouldn't rely on it. I however do abuse that a lot by using 1pd. If i see the car doesn't see the stopped car in front i will pause ACC, let 1pd start slowing down, then reenable ACC. the car will very quickly pick up on the stopped car and work like you want.

Do you have the car set at max distance from the vehicle in front of you? What lane assist aggressiveness do you have on? If it’s on high or aggressive, try normal. It did wonders for me.

... I'm curious if anyone has tips for going from ACC to turning it off while in 1 pedal without some kind of big lurch?

My specific example is I'm in the right lane (probably should just avoid doing that) with ACC on and a car is aggressively merging on and I'm worried the ACC won't see it so I want to disengage and slow down a bit without slamming on the brakes. Do you just use the brake pedal at that point? Normally in 1 pedal I'd feather it a bit so it's not anymore sudden than it needs to be. But if I just disengage ACC altogether, regen is going to kick in hard unless I find a good spot on the accelerator pedal which is a bit difficult.

Do you just ride the brake? I'll definitely eventually get used to it, but I find the brake pedal on this thing pretty dang sensitive. So while it seems like a normal reaction to ride the brake, I'm wondering if there's other options as well?

Just press the middle button on the left. It will turn off the cruise and you'll start to slow down. It's the scratched button in this picture.

yes, THIS.

My recommendation is to turn off one pedal mode when you are using ACC.

My commute is mainly highway so I use ACC and lane centering a lot in my Leaf since 2019. I hardly use one pedal mode. I only use it as an auto brake hold when I'm the first car or when I use drive thru lines.

NOT this

Yea but then regen kicks in pretty hard, no? I mean yes that's better than slamming on the brakes unnecessarily, but still seems a bit aggressive.

Put your foot against the accelerator pedal and then hit the ACC engage/disengage button as Zackwyatt showed. Works like a charm, although it does take a little practice putting pressure on the pedal so as not to accelerate or decelerate.

My problem is that ACC accelerates WAY too fast when resuming. A bit of a drag … makes me not want to use it at all & no, speed recognition is not enabled.
