brake assist.

[Packy]

Curious, I know if your driving with adaptive cruise controll and the cars come to a slamming halt, the adaptive will stop you fast. I've experienced this, its reaction is so fast it scared me.

What about if your spacing on your cell phone, eating the Whopper and chugging a cold one while yelling at the kids, without adaptive on and you fail to act on a row of stopped cars? Or a wall? Will the S6 stop its self?

Recently I say a test of several cars on some TV show that showed many cars with some sort of brake assist will slow but not stop. MB and BMW did not. The new Subaru system did stop completely from 45. Anybody be unfortunate enough to have to test this?

Was wondering about the exact thing on the RS7. Would love for someone to give feedback.

Not sure of stopping but my A6 did go bananas on the brakes once. I was the usual speedy gonzalez when all of a sudden the tc in front of me just slammed the brakes to turn right. And my car shut the moon roof in a flash in addition to slamming the brakes.

I saw the video, but if you notice, in all cases, it was following a car that braked abruptly. Ive experienced that aspect. My question is one that was already stopped. That is a bit different. Other manufacturers claim their cars will stop to avoid an object, but as far as I know Subaru is the ONLY car that has been proven to do this. I'm not about to "try" that one. Maybe someone has. Accidentally of course.

I've only known that reference to mean a cold beer. Hopefully you are referring to something else.

snagitseven's post is spot on IMO. Mine came with a separate pamphlet explaining presense plus and it was clear that you cannot rely on the system to avoid a collision, only to engage to lessen the impact. Since the system doesn't intervene until the last minute you couldn't expect it to completely avoid a collision in all cases, but I don't doubt the poster who reported that it did just that because if the laws of physics would allow it I'm sure the system is going to try to stop a collision by applying maximum braking force.

I had an experience where the system engaged the brakes to avoid a collision. Going 30ish in a residential area the car in front went to turn right and I (intentionally) did not slow intending to gently swerve left to go around him but I was cutting it very close to him. I'm sure the maneuver would have worked fine but it was close and the system engaged the brakes. Surprised and startled me. On other more appropriate occasions I've received the dash and audible warming but I was being attentive and it never engaged the brakes for me.

I've gotten the warning several times. Other than that a few days ago car in front of me going about 45 mph, tire popped. The car immediately started braking as if it were coming to a full stop. Though at the same time I was swerving to the next lane.

LOL. I was throwing in all the things your not supposed to do while driving. But if it helps, a cold soda you got with the whopper. [:D]

Perfect post. I watched the videos. Basically it will most of the time, but miss on a few according to a few who have actually tested it. I really like the one from gatorguy who said his wife rearended someone. Leave it to a woman to cause an accident WITH an anti accident feature. Sorry women, had to go there. Maybe it wasn't even turned on.

Ive rearended two people in my time. Both in work delivery trucks, one was a bonifide brake failure where the pedal went straight to the floor with no resistance. I had time to say "OOOOOOH craaaaaapppppp".

the other was when a woman in the middle lane decided she missed her right turn and went ahead and made it. 4 cars laid rubber to the road. My little Toyota wasn't as adept at stopping as the 3 infront of me.

Two got me also, one drunk, one another brake failure, line came loose.

Luckily, no accidents or tickets in 22 years.

Bwahaha. Everything is right ..just dont get caught..

To the OP's question, this system will not intervene with "stationary" objects.

[HyperM3]

Do you speak from experience?

Yeah, check my sig.

[HyperM3]

Let me clarify the question. Has it happened to you?

No, however, I also don't want to try it considering in all the literature that is written about the adaptive cruise and its components have stated that it will not work with stationary objects.

That being said, the brake assist has saved me several times when in traffic. I think the person in front of me is going to go faster than they actually do and I end up pressing the gas harder than I should. Then I hit the brake to avoid tapping them, the assist kicks in and stops the car dead in its tracks.

It states in the manual that stationary objects are not considered for the accident avoidance system. Too much computational algorithms probably. Although, I've seen some commercials that suggest other cars do include stationary objects...

I am not really sure of that. I always hit rail tracks on my way to the gym and one day they were redoing the road around there. My 6 almost stopped right before rolling on to the rail tracks . Culprit- a wide band-aid patch kind of road they laid down just at the edge of the tracks. So may be it does engage with stationary objects also. On a side note - the DIS said : brake guard "ENGAGED" . I felt like an F16 pilot :P :P

Interesting reading these anecdotes after having originally saw the IIHS results (see link). In their tests they use a stationary object that looks like cloth (ie infrared won't pick it up, radar may not reflect the same) with a frame of some sort holding it up so it "looks like a car" to human eyes.

The Audi slows down to ~1 mph in the slower test, and it doesn't even engage the brake in the faster test (true to Audi's documentation). Also, it gave a warning, so I bet the auto-braking would have engaged if the tester had tried gently touching the brake in reaction to the audible and visible warning.

I had the warning go off once while I was driving on the freeway and a slow car decided to merge in the freeway behind a large truck in front of me. Definitely a neat experience, as I was looking to pass the truck and would not have noticed as quickly otherwise.

No, thats a completely separate feature to stop at all rail road crossings like a bus. Audi doesn't advertise that one but now the cats out of the bag. Is there nothing these cars wont do?

[Tampaukfan]

Mine has engaged twice, both times it scared the crap out of me. First time I was coming around a bend following a mini van.
A box on my passenger seat slid off and I reached to grab it, van slowed considerably and the brake assist engaged and the seat belt caught me on the throat.
The car came to a complete stop and the van ended up stopping too so it did save me from a rear end collision.
Out of all the options I have had on my cars the brake assist is by far the most useful one and Ill never own another car without it.
