Highway Assist

[vcbuddha]

Has anyone else noticed that the Highway Assist is not working as well after the most recent update? After the last couple of map updates, it seemed to be working very well, consistently keeping me in the center of the lane. But, after the last big update that came out, now it's weaving all over the lane again. It seems like every time there's a new navigation update that comes out, it screws up the highway assist function. Is it just me, or has anyone else noticed this too?

Just be careful. HA is definitely not designed for non-highway use.

It is geo-fenced to work only on certain roads. I drove 3800 miles from MOntreal to DC to SF Bay area mostly HA 72mph and some of it in rain at night in construction zones where I lowered it based on speed limit, curves and mild slopes. It worked nearly flawlessly including the left or right bias.

What was the thinking behind Highway Assist?
Is if for people who like to play with their phones while driving?

 

[Cosmo Cruz]

Huh...decided to read the Owner's Manual

I see now that I was trying to find Adaptive Cruse while in Highway Assist. It just turns it off.
You have to select Adaptive Cruse with the Dream Drive button first. It's not the default. So you have to go the wrong way to get there.
I keep thinking I know how this car works.

I'm going to try driving with the steering wheel all the way up and the seat all the way down so I can see the display. I'm trying to figure out the dimensions of the person who designed the cabin, and how the heck he can drive for hours in that position.

Keep your hands high, your butt low. look comfortable for a long dream drive ?

I have no idea what you’re talking about - honestly. You do not need the Dream Drive button to select ACC first. You can switch while HA is engaged, with a long press of that same button.

Can you or someone with you take a video of what you’re doing so we can assist?

Fwiw, I have no trouble seeing the screen and am very comfortable. But I sit very low in the car, as I always have in other cars. (Part of why I don’t like SUVs)

All I’ll say is that I’m very disappointed now w HA, I recently took delivery of a Rivian R1T and theirs is 100x better than LUCID. I was ok with Lucid’s until I tried my R1T on the highway , much more stable, better lane change, and most important to me, you just barely have to place your thumb on the wheel and it never asks you to take control.
For a car that has been on the market a year earlier than Rivian and costs 50% more, I expect more, I really hope they improve on HA at leqst to match Rivian’s experience.

I agree that Lucid can and should HA. Lucid has not been on the market longer than Rivian. Rivian started production a couple of months before Lucid.

I guess you are right, their Launch edition was ahead of the Dream Edition but I took delivery of my AGT in April 2022, I think before regular deliveries for Rivian, or maybe not. The important part is they need to improve their HA, especially hands off or minimal touch and lane change, also I get patches in the middle of interstate were it suddenly goes off for a couple of miles(not available) and that is dangerous.

Lucid has told us that hands free HA is coming this year which means soon. I hope additional improvements come after that.

My car was built the same month as yours. The car will alert you quite clearly if Highway assist is not available, so I don’t think that makes it dangerous if the car tells you something is not available. However I’m sure yours is misbehaving as I was having random issues with highway assist quitting but then also not going into cruise control even though it would say it was in cruise control but greyed out, and it turns out the batch of cameras in our cars may have some issues. Service investigated mine thoroughly, found the cameras were part of a batch later determined to have the potential for error or failure and replaced them. Since then my HA works better, a bit better than the ADAS in my Volvo V60 PHEV which also has similar incorrect “hands on wheel” alerts too often. As @Adnillien said Lucid service also told me hands free ADAS is coming soon.

along I-20 and I49 HA suddenly quits and becomes unavailable, when you are doing 70-80 miles/hr on HA and it suddenly changes to adaptive cruise control it can be dangerous, then after 2 miles of the same highway it suddenly becomes available again, is always same stretches of highway so is something on LUCIDs maps that is wrong. the car does not alert that HA will become unavailable in the next few miles, it just automatically switches and if you are not paying attention it can be a problem.

How is the cellular reception in that area? HA requires connectivity where Adaptive CC does not.

 

[Hcuellar77]

didnt know it needed cell reception, it could be that then, my cellphone works fine but it the car's antenna is weaker, it does happen at stretches in the middle of nowhere.

 

[ATP2023]

Fascinating! What highway has traffic lights and intersections? I wonder if it was mapped?


If you have timestamps, send those to customer care - they will have the engineers look at the data. If not, save timestamps in the future and send ASAP so they can pull logs.


Haha yeah, this is a known bug. It's a bit overzealous right now, particularly when backing out - often sees cross-traffic that is across the street, lol

I wish Lucid could add the ability to put time stamp when the car does something so they can view. Rivian has the ability to by pressing and hold the Hazard button to create a time stamp report.

That’s not a bad idea!

 

[Bunnylebowski]

Yeah that’s a good idea, I had to remember the date/time and then tell Lucid. They can still pull logs for the event but it helps if you can tell them when. The other thing I really wish Lucid would do is allow you to view the actual error message, usually it’s gone off the screen pretty quick and then you just have the meaningless orange alert triangle.

That’s a different problem than highway assist failing for another reason, it really doesn’t alert you in any way when you’re in HA that it’s disengaging? That’s not normal behavior, even in a non-mapped area it will come up with an orange map icon and alert that HA is not available. I have seen that happen if it had prolonged loss of cellular but never just switching with zero alert of any kind.

it does say HA not available but at the same time it disengages and switches to adaptive cruise, I don't consider that a warning of any kind, couple of times it has caught me off guard not holding the wheel and it swerves to one side, not much because I have lane warning but still scary. Driving the same stretch tomorrow, will try to see exactly what is does and mark the spot.
