Do you fully trust your self pacing cruise control?

[EdP]

The collision warning reacts to distance and rate of approach of the car in front of you.
Still confused. I thought if the collision warning comes on and you do not break accordingly, it will slam on the breaks on its own.

Guys?

Yes, it is supposed to and a couple of people here reported that it does. I just hit the brakes rather than try to find out.

You must adapt and gain trust in the system......then its the best thing ever invented!!! Takes confidence to put full faith in the adaptive cruise control, but once you are there......it is awesome.

Will someone volunteer to build a barrier out of something soft like cardboard boxes and then drive your car into it at high speed to see what happens.

Won't work. You need more mass. There was an explanation some time back but a simple barrier like boxes or sheets of paper does not activate the system.

You need to build a simulated Parking Lot out of aluminum foil.

I’ve had my collision avoidance system activate several times and it almost caused me to have an accident. If your passing someone while simultaneously approaching another car from the rear in the open lane and your intent is to slip into a hole in front of the slow-poke in front of you being passed, be careful. As the sensors see a rapid approach to the rear of a car In front of you and them not knowing your getting ready to change lanes, the car will brake right about the time your ready to cut over in front of who your passing. This can cause the vehicle your passing to run up your butt real quick. It’s happened to me twice now. I’m in control and the car says no, I got this and it takes over when I don’t need it to, startled the piss out of me. Yes, I know I probably should drive more careful and I generally do. Occasionally an idiot driving turns in front of me going 5mph and refuses to come up to traffic speed and I just quickly pass them and slip back in front. The 3.3 certainly has the power and ability to do this, just be careful for when your ready to zig and the car says, I’m braking first as you just started to change lanes. Not a good combination of events.

A few weeks ago I was following Yogi Berra's advice to take the fork in the road, heading into the left lane of the right fork when someone to my right swerved into my lane. I slammed on the brakes and turned hard left at the same time to avoid the other vehicle. I don't think the AEB system activated, maybe because I was braking. Luckily, i ended up in an open V-shaped area dividing the two arms of the fork and didn't hit anything.

Admittedly, AEB is different from adaptive cruise control that is supposed to bring the car to a stop if the vehicle in front does and start again if under 3 seconds. I have to admit I've never tried that, though I've used cruise control often.

How does a radar system measure mass/density?

I don't know but it was posted here some time back as to what the parameters are for it to work. The box idea has been brought up at that time.

 

[Regor60]

0-60 in 5 seconds takes 1.5ft to get up to 5mph... lol

So you're recommending flooring it towards a parked car ? Momentum may not be your friend

That's if it sees the car in front of you. If you're both rolling and the car in front panic stops then it will work. The radar was picking it up the whole time.

If a car is stopped at a red light 2 blocks away, you'll slam right into it. The radar didn't pick it up because it's not moving.

I also said the system won't work and you'll hit the car... so... be quick? LOL

Is there any difference between the 2018-2021 G80's Adaptive Cruise Control & Lane Keep Assist vs. the 2019-2021 G70's Adaptive Cruise Control & Lane Keep Assist?

I remember reading something a while back about how the G80 had an older LKA that was kinda bad and an older ACC that was untrustworthy. Not sure if Hyundai improved it with the G70s.

Like I said, the cruise control whould shut off occasionally "conditions not met" in my 15 G80 but never in my 19 G70

Interesting. I coulda sworn I read something 1 or 2 years ago about how Hyundai did small upgrades to the ACC in the 18+ G80 vs. the 15/16/17 model years.

Does anyone else who own a newer 18+ G80 be able to comment on how it stacks up against the G70? I like the G80's plushness, but it does seem like the G70 has slightly more refreshed tech -- brighter & sharper backup camera, higher resolution (?) infotainment screen (albeit 1" smaller which could be why it looks sharper), and potentially better ACC/LKA nanny assist features.

I had a 2015 and now a 2018 G80. The ACC works equally well but going from memory the 18 has a setting for faster acceleration on resume.

As for the LKAS, not impressed by either. I get some vibration in the steering wheel if I go too far to the side. On a gentle right curve, if I take my hands off the wheel it tracks the curve but puts my left tires on the yellow line. I don't really feel any assist in normal driving.

My experience with adaptive CC today. I drove 950 miles. Of it, 900 in interstate, at least 800 allowing the CC to do the work.

In both South and North Carolina it rained off and on. For about 200 miles, due to weather and traffic, speed varied from 10 mph to 80 mph. It was up and down every couple of miles too.

All I did was steer. Even with people cutting in front, it slowed down perfectly. Certainly .made the trip much easier on me. Another 250 miles in the morning and my friend will be making us a G & T with lunch while looking out at the ocean.

I think is is natural for drivers to not trust a vehicle's collision avoidance (CA) system. After all, many of us have been driving vehicles for a long time now that had no CA technology whatsoever, other that the one in our own brain. And as applied to everyday life, our internal CA system keeps us from walking into walls, tripping over objects on the floor and so on, so being alert is ingrained. And it's a healthy mistrust, too. It keeps us from becoming complacent, usually followed by "crunch" sound.

After driving a BMW 750 and a BMW 640 for 3 years each, I have found that the CA technology does work. in keeping my foot near the brake pedal, though, my motto is--to use Ronald Reagan's words--"trust, but verify".

How much confidence you have in your pacing cruise control.?

I find that if I'm coming up fast on a stopped car I will unconsciously override the system and put my foot on the brake.

How about you? Do you fully trust anything electronic?

I love my adaptive cruise control. It took a little while to feel comfortable with it, but now I can’t live without out it. One thing I learned is that you can adjust the distance between you and the vehicle ahead. 1 car length is way too close and I found myself overriding it a lot. 3 car lengths is too far apart as that invites other drivers to cut in front of you. But for me, 2 car lengths is just right.

Wait until your next Genesis with HDA (Highway Driving Assist). You don't have to steer, just make sure you are touching the steering wheel so it doesn't alert. Way cool!

And it doesn't try to take exit ramps anymore.

My experience with LKS and the ACC in my G70 has been pretty great. The ACC tends to be slow to react to cars accelerating away from you, I guess it's better-safe-than-sorry programming. I like how it does not freak out when someone cuts in front of my car on the highway, it just gently starts to slow down to the programmed distance. It will occasionally move in towards a slower vehicle too quickly, and then slam on the brakes. Its traffic jam features have been flawless for me, as another poster reported earlier.

The LKA is also great. Ed, the (your) G80 must have different programming, or sensor setups, but my LKA is awesome. It centers well, and follows curves quite well, even fairly tight ones. Today it drove for almost 12-13 minutes through a series of curves before asking for intervention. It does 5-8 minutes with any intervention on a regular basis. Mine appears to be a sort of combo between LKA and Gen/Hyundai Highway drive assist. I had the chance to sample HDA on a 2022 G80 for a 900 mile road trip and - while better than my G70 - it behaved very similarly, but with more features and a bit more accuracy. But my 2019 G70 3.3 Elite's LKA is very functional, useful and accurate. I very much trust it (up to a certain point). You do have to pay attention, as you should be, and rescue it, or just touch the wheel form time to time. But overall, it's great and a real sanity-saver on long drives. I love it. Very windy days are its enemy, though.

I remember reading somewhere that the 2019 G70's LKAS and ACC saw improvements compared to the 2018 G80. But then Hyundai improved on those features further in its 2020 Palisade and Sonata. And recently, someone else mentioned Hyundai improved on the 2020 Sonata's system in the 2021 MY.

In my test drive of the '21 Sonata, I thought it had the best LKAS system that I've ever felt. But everything else felt like an step down than any of the slightly older Genesis G70 and G80s.
