Smart cruise

[atc]

hey I just bought a new 2011 3.8 with all the bells etc but I dont think much of the so called smart cruise , does any one know if the smart part can be turned off so I just have normal cc
Thanks

You can set the distance to just one bar and then use it in most cases like old tech cruise control. BTW we love the smart cruise and use it everyday in Atlanta GA traffic and it works flawlessly.

My Infiniti G has an “Intelligent” cruise control which is the same thing but uses a laser for operation versus a radar system like in the Genesis. My G can operate in ICC mode or normal mode. I originally was disappointed in not having that option in the Genesis because one day the sensors were covered in mud and the SCC was inoperative. So no cruise. That wouldn’t have happened with my G. But let me say this the SCC in the Genesis is far superior to one in the G. Like homeostone said I use it mostly all the time. Whereas on my G it’s only a highway tool. I’m really sold on the Genesis SCC operation and find it adds to the cars enjoyment. It frees me up on a mundane task to enjoy my ride. I think after you’ve used it for while and develop some confidence with it you’ll appreciate it more.

You will love it on a long trip. I set mine to one or two bars depending on how much traffic in on the road.

Curious as to what you don't like about SCC. I prefer it because I don't have to be nearly as vigilant about the vehicle in front of me slowing as I did with my old CC. The only other feature I'd like is some clear indication that my speed has dropped below the set point - for example, if my set speed is 75 and the car ahead slows to 72, I may not notice the difference for awhile.

Whether you like it or not I discovered some unique traits about it during a two day 1200 mile drive. I don't know how better to explain it but but there must be some kind of an accelerometer in the car. As I drove through the mountains of WV on a freeway, the road is relatively twisting, if the car felt some lateral "G", side to side, the car slowed down several miles per hour. Also, if the car went through a dip in the road and then experienced less than one G out of the dip it also slowed. I'm no hallucinating. I experienced both many times. The system is great but takes time to adapt to. I found myself using the cancel/resume buttons a lot in traffic. I set it on one bar but it doesn't let one get close enough to a car in front of you to let the lovers of the left lane know you want to get by.

Stoof Pilot, I know what you flew, I've got a couple of hundred traps in F-4s.

Are you sure that the variations you experienced weren't related to periodic loss and re-acquisition of the "target" ahead? I've found that on winding roads the radar will lose contact with the car in front of me as it heads around a curve, and it will also sometimes respond as if it's receiving echoes from the roadside barrier. There may be similar issues with hills and dips.

I find the Smart cruise works well, but I agree with others that the ability to turn off the 'smart' part would be a very welcome addition. I find on crowded highways with traffic changing lanes in front of you on a regular basis, the cruise will invoke braking causing unwelcome deceleration and much confusion to following drivers. I know the system is just doing its job, but I find I now have to anticipate such changes and hit the 'Cancel' button before the brake lights come on.

I have experienced the same - I notice on the on ramp that I guess the car thinks I have too much speed

I like the SCC.... I would like that it be a little 'smarter'. It needs a camera to identify things like brake lights so that it can prepare sooner. SCC IS NOT good when sudden traffic stops are involved.... like when you come up on an Interstate backup. If it could 'see' further down the road it would be able to anticipate this condition.

Set the distance to one bar.. in close traffic. Most of your concern will disappear.

Thanks for all the replies , it seems I have to live with it apart from that I am so far very happy with my new Genesis. BTW I rebadged today and the trunk looks much better

 

[Skywagon]

Waveman,
Perhaps you could be correct, I honesty don't know. I don' think the dips were deep enough to cause a loss of contact and there were no cars in front of me during most of the turns. Perhaps it was painting the guard rail? I've got 1200 more miles to go. Will try and figure it out.

I am amazed at how well the system handles cars merging in front on the highway. If they merge in and are pulling away the system just eases off the gas to re-establish the following distance but if someone merges in and is not accelerating away the car does not hesitate to throw out the anchor. I was in heavy traffic with the following distance set to one bar. A car merged/cut in front of me and stomped on the brakes. Instinctively my foot moved for the brake but my seat belt was locked and the car was braking before my foot got to the pedal.

This thread got me thinking...

When the car slows due to SCC, do the brake lights go on? Obviously, if I were to slow significantly, the driver behind me should be alerted with brake lights. Of course, the flip side would be if the SCC was making many slight adjustments then the brake light would be coming on too often.

I would think that the way it should work would be if there was a slight decrease in speed just by getting off the gas, then no lights. If the car were to apply brakes for a more significant decrease, then brake lights would be needed.

Any idea how this works?

 

[pilotdane]

It works like you think it should. If it can control your speed with the throttle it does but if it must decelerate faster then it uses the brakes which also turns on the brake lights. I've been wondering if it would be useful or just annoying to have a brake light indicator on the dash. It might be nice to know when the car is turning on the brake lights but in the end does it really matter? And, would another idiot light blinking on/off be more annoying than good? It might lead you to not notice an important indicator illuminating... like that annoying oil symbol.

It should be easy to tell when the SCC detects a vehicle ahead by the car pictogram that appears in the display. What I don't know is how well its algorithm differentiates a stationary object (like a barrier) at the side of a curve from a real car. You'd think that it'd be simple, but I bet that there are circumstances under which the system is fooled one way or the other.

On the 2012 the display in the middle of the dash showing your car and the distance bars will light the brake lights on your car in the display when braking. I love that display, lots of cool and even sometimes useful stuff going on there. I just wish I could change the color of the car in the display to match my Cabernet Red car. LOL

The computer must keep track of what it sees and decide what to ignore. I have never had it lock on or have a false alarm for anything stationary by the side of the road or oncoming traffic. It probably knows your vehicle's speed and disregards anything coming at it at that speed. Then it probably throws out anything closing at a very high rate relative to your speed like oncoming traffic. That leaves things traveling at a relatively similar speed to your car.

So far I've had two false alarms that caused my car to slow down when not required. Both times I was on a multi lane road and it locked onto a car in an adjacent lane. When driving on hilly two lane roads I will sometimes see the car symbol on the dash blink on and off when the car I'm following is at the extent of the three bar following distance. All in all I am amazed at how well the system works and it's been a dream come true on long trips in traffic.

 

[tazrig]

since this is a radar based system does anyone know if it messes with radar detectors? in other words if you have one on your window does the scc set it off when on?

 

[tompass]

No problem with use of radar detector.
