Comments on Adaptive Cruise Control

[Rey]

My initial reaction to the concept of adaptive cruise control was, at best, skeptical. I wondered if it could be turned off.
Now that I have used it extensively on the first 2500 miles of my 2011 Genesis, I can say that I am dazzled by it. You cannot, to my knowledge, disable it. If the front "view ports" of the system become too dirty/snowbound to "read", then the system will not engage.
You can set the system for any one of three following distances. The system ignores cars driving faster than you or cars in parallel lanes.
Where the system has really shined is travel on two lane highways following cars who do not maintain an even steady speed. Constantly adjusting one's speed to match that of the proceeding car is tiring. The adaptive cruise control does this speed matching quietly and effortlessly.
My understanding is that the adaptive cruise control will not necessarily cause your car to stop before a stationary object, like a deer or a stalled car.

If it detects a non-moving object in front of you it will bring the car to a near stop. A beep will go off telling you it has disengaged and alerting you to step on the brake to complete the full stop. It generally beeps around 5 mph when I have used it.

My first experience with adaptive cruise control was on the highway on the way home from the dealer. A car jumped into my lane and it worked like a charm, slowing then picking back up when the road was clear. I have used it some since then but can't make myself trust it completely. Should be really useful for an impatiemt driver like me on a fairly crowded highway. We'll see.

My G has the “Intelligent” cruise control and I’ve used it since I bought the car in 2007. In the beginning I wondered if it was a viable option but soon after much use my confidence in the system was reassured. I use it a lot mostly to curb my enthusiastic tendency to go fast which is easy with my G. This gives me some insight on the difference in systems between my G and my Genesis. My G uses a “Infra Red” sensor to achieve this marvel of technology not sure but I think the Genesis uses a Radar type of sensor to achieve same. As much as I like the system in the G the system in the Genesis is superior. The small nuisances that have to be tolerated in the G have been overcome by the Genesis system. For one with the G if somebody jumps in front of me even going faster it immediately slows down. It can fooled very easily by a very slight turn in the road being an Infra Red type sensor its beam is very narrow. It’s resume time after slow down is too slow. It suffers from an inherit system flaw associated from its Infra Red operation driving towards the sun at sunrise causes the systems to turn off. A known problem.. My Genesis has proven itself much easier to live with no oddities yet. Both systems work well and my G is a blast to drive but with the Genesis I don’t have adjust to it. .

Tracking of the adaptive cruise control is very cool even on a crowed 5 lane highway, the sensors turn with the headlights, lol

I also found that the adaptive cruise control applies brakes when coasting down a steep hill with no car in front, very cool

I've been impressed so far, but still have trouble trusting it. It would be great if the system provided some visual feedback in the display when it slows down or speeds up.

Well, it does, you just have to pay attention. The speedometer for one. Also, if you try to manually press the accelerator when the cruise is set, the display will flash and tell you what the cruise is set at.

When the cruise slows down significantly you can feel the deceleration noticeably and vice versa when you speedup.

Actually, after just completing a drive with over 1,000 miles with the cruise set, I trust the system more than my manual driving skills.

I know that significant increases or decreases in velocity are noticeable on the speedometer and in the seat of my pants. But having some visual indication that the car is responding to subtle changes would help boost my confidence that the system is doing what it's supposed to do. I'm still new to it, though, and I think that over time I'll learn to trust it more.

 

[CenTexan]

I'm impressed by the system as well. I do wish you could select to have a small indicator come on when you are cruising below the speed limit (as caused by a slow driver ahead of you). It's easy to enjoy the ride and so not pay attention to your speedometer, finding out that you are actually travelling under the speed limit. Minor concern, tho.

BUT - does anyone know if the brake lights come on when the system slows you down? IOW, do the folks behind you see your brake lights and so know that your vehicle is slowing down for a slower car in front?? Could be dangerous if not!

Yes they do. It's AWESOME. I love SCC.

If they didn't I'd be dead already. It stopped my car several times already!

I wonder if there is anybody else here who, like me, never uses cruise control...
(My commute is about 10 minutes on a very crowded road, and on the rare occasions when I'm traveling on a high speed road I never remember it's there)

I wasn't a big fan of cruise control with any of my previous cars - it seemed to require more attention than it was worth. But the SCC on the Genesis is changing my mind, and I'm starting to use it under conditions I wouldn't have considered before.

(I would love a 10 minute commute, though!)

I actually use cruise control sometimes in areas with very low speed limits (25-30 MPH) and fruquent speed traps where I would otherwise drive too fast and risk getting a ticket. Also do like it on the highway especially with the adaptive feature.

Once you use the adaptive cruise control you will love it and appreciate how it makes driving easier.

The only time I use Cruise Control is on a long Road Trip. I never used it for the first 4 months I owned the car. So, I did not know how sweet this feature was, until I took a 1400 mile trip.

With that said, some people adapt to new technology more willing than others. I have an older friend (75) of mine that got a Subaru with remote keyless entry. He refused to use it, (Very Stubborn) choosing to insert the key and unlock the lock the drivers door, and then he used the power un-lock to unlock the doors. When he parked the car he would hit the power lock and then close the drivers door. One time we were on a 350 mile road trip, and he stopped at a gas station. He left the car running and instinctively hit the power locks and closed the drivers door. He just locked us out! -- This cost him $45 to call the service guy with a 'slim jim'. I tried to get him to use the remote key, but he still refused saying 'that this has never happened before. - Did I mention he was stubborn?

Your friend has a few (fewer than 10) years on me, and I can see how that could be. I'm not averse to new things, but I'm not interested in stuff that clutters or does not improve my life - as defined by me - in some way. I have never liked or cared about cruise control before, and I still don't. I don't have the tech package, so I don't have the ACC anyway, but even if I did I wouldn't use it. Keyless entry is another matter altogether, although after owning my Genesis for nearly a year I still sometimes reach for my keys as I approach the car. Old habits die hard, and the older you get the harder they die. .

I went to 2011 NY Auto Show yesterday and no one on the floor could answer my questions on adaptive cruise control so here they are:
1. If car in front of you comes to a complete stop will the ACC stop you completely without your intervention?
2. If you stop completely without pressing the brake will ACC then accelerate you when the vehicle in front of you accelerates without reengaging the system.
I feel that this is critical in stop and go traffic.
Thanks.

Can't say about complete stop, however the acc has slowed mine from 65 to about 8mph then resumed the set speed when traffic started moving again. I use it almost everyday and it always works great.

As I stated before I’m really satisfied with the operation of this SCC. I use it most of the time even in heavy traffic it’s that good. Its recovery time from slower is very good. Its reaction and tracking ability is excellent. Like stated before It’s very useful in very slow situations that are particularly difficult to maintain. Like I said before I’ve used SCC before in my G35 but because of its nuisances it was only useful in light traffic or highway conditions. Not so with this system. To address your questions when I drove off the lot last December I waited 2 weeks to make sure there were no problems and drove to Florida. This gave me extensive time to use and test this new SCC system especially as compared to my G. To address your questions. 1. I tried this test many times, with the SCC enabled the car will come down to about 5 MPH (which is damn slow) beep to alert and roll SCC needs to be reset (resume). 2. If the car slows to above 8 or 9 mph it will accelerate again to set speed.
