Adaptive Cruise Control

Trust is the magic word here

I had an idea it would but chickened out at 8mph when all the beeping and lights flashing forced me into putting my foot on the brake. I was called an idiot on the old site for testing this feature.

Hi BOBO, FWIW, my 06 Base WILL COME TO A COMPLETE STOP by it's self unless I step on the brake and believe me, that's VERY HARD to keep from doing just to show off.

When I'm going about 35 and come up on another vehicle that it stopped, mine shuts off at about 3 MPH. then the annoying beeping starts and the red crash symbol comes up in my HUD. My ACC never brings me to a complete stop...

The other question would be what does the driver of the following car see if the acc suddenly makes our xlrs stop? Do they see brake lights or what?

Yes... anytime the ACC comes on and brakes, the brake lights come on to warn the drivers behind you. Pretty cool, huh??

 

[hawkeye372]

I guess I'm always driving so wasn't sure. Unless I get out and run behind the car as its going down the road, I would know. Unless I take it out at night and concentrate on the rear view to see any reflection. But then that too would be dangerous because you would take eyes off the front traffic Not recommended.

Hawkeye,

You must have missed my earlier post.

Jack - I have my windrestrictor hooked up to my brakes (gets brighter when brakes applied) and the windrestrictor definitely lights up when the ACC slows down ... but my guess is that because the foot pedal is not depressed, the ACC is not deactivated (I don't think the ACC is tied to the brake lights - but rather the brake switch at the foot pedal... just guessing though).

When I preformed this test, I was on a metered on ramp, up hill grade, and my car did come to a complete stop and the engine rpms dropped to idle. I did have to hit the brakes because the car started rolling backwards.

Now that I think about it, the ACC could have shut off at 3 mph and there would not have been enough forward momentum to keep going forward.

This on ramp is about the longest one in my area. If you go to Google Maps and select the Manchester Blvd. to the I-405 freeway South and select the satillite view and zoom in, you'll see this on ramp on the west side of the I-405 freeway.

A few of us gear-heads around here us it as a small drag strip (Not legal) to test mods we've made on our cars. Of course, we only do this early in the morning when the traffic is light. If we want to race each other, we'll pull up to the meter lights and wait through a couple of cycles until the cars in front of us are out of sight then when we get the green light, we'd take off.
This on ramp is two lanes and has cement walls on each side with chain link fencing on top of the walls.
It is about an 1/8 + mile flat and straight then it starts the up hill grade and into an 'S' curve before it merges onto the freeway.
This is where I tested the ACC at rush hour in the afternoon when the freeway was bumper to bumper south bound and I could get up to 30/35 mph to set the ACC.
I was behind one of the yellow county road maintenaince trucks with the big protective rear bumpers incase the car didn't stop, it would do little to no damage to either vehicle. When my car stopped, I noted that there was about 3 to 5 feet distance between the vehicle and the warning lights and beeper were going off until I stepped on the brake peddle when the car started rolling backward.

You must have nerves of steel, I have tried this too once but never tested it further, very freaky.

I was actually wondering if as you come to a stop via the ACC and assuming the ACC does not kick off upon stopping, does the car start driving forward when the traffic does? That would be interesting in a traffic jamb on a freeway.

 

[BusaMan]

I just had to try this. Mine nearly came to a stop, but crawled toward a collision at 3 mph. At that point, it was easy to just stop the crawl. I suggest you set your "gap" to a bigger distance than you normally use, just to keep you from a cardiac incident.

It's really not hard to do, as long as you cover the brake pedal because when it kicks off, and it does kick off, you have to stop tire rotation. When I had my 04 I never used it in heavy traffic because everybody would keep jumping into the space in front of me which would make my ACC really slam the brakes on. I remember having three or four car lengths in front of me while using it and I had it set to the closest tolerance. Out here in La La Land that's an invitation for a couple of cars to dive in.

No Sandy, my ACC kicked off and you can not re-engage it until you're up to about 30 mph.

And the ACC in LA traffic is useless because it dosen't matter how close you are to the vehicle in front of you, some idiot will always cut in of front you!
If traffic is moving at the rate of speed that you can use the ACC, it will only allow you to get about 3 to 5 car lenghts close to the car in front of you and at that distance, cars will be continually getting in front of you and after a few cars do that, you'll find that you're hardly making any forward progression and you shut it OFF.

........and at that distance, cars will be continually getting in front of you and after a few cars do that, you'll find that you're hardly making any forward progression and you shut it OFF.

Absolutely! In very heavy traffic the ACC is not advisable. However, if you are cruising on an un-crowded highway either crack at the of dawn on a Sunday morning in California or crusing from Chicago to Davenport Iowa on I-80 it is great!

I know this may sound a little weird but I use mine in heavy traffic for unseen slowing!
If you set it at around 40-50 and traffic flowing around 60 then I use the gas pedal to roll with the flow and suddenly there a quick slow down before you get from the gas to brake the ACC will already start slowing the car! Those couple seconds could save a accident! "Just Sayin"

No, not weird at all, unless there are two of us that are weird. I used to do the same thing to keep the space closed up.

What! Okay, we are just going to have to keep a much closer watch on you guys. This guy and his guard dog have volunteered for the assignment.




If you see them don't be alarmed and yes, they are watching you.

I thought this was an ACC-related thread. After Tyrones's threadjack, it should have been re-directed to a new thread. Threadjacking makes it very difficult to find info later on.

What threadjacking are you referring too? I only see one post by Tyrone and it was all about the ACC
