Does the ACC function in a way that helps to avoid "distracted collisions"? for example driving in town you look away and the car in front of you stops abruptly, does it auto brake? if the answer is yes does the ACC need to be turned on each time? I have been to 2 dealers and have received conflicting answers.
Does it work like this? How does Ford Pre-Collision Assist with Pedestrian Detection work?
or is it just fancy cruise?
Thank you for the help as i really want to get this thing ordered soon!
Just picked up my rig today and drove 120 miles with adaptive cruise control active. Never hit the brakes and ranged from 65 to 20 mph. It was weird to trust, but the brakes pushed hard when traffic slowed quickly. Hope that helps, but I'm not going to test a close call.
If you were driving in town and a child ran out or a car slammed on the brakes ahead of you and the cruise wasn't on would the truck auto brake?
No it wont auto brake, with the cruise off, the collision avoidance system will warn of possible collision and if you dont tdo anything will pre-charge the brakes so when you do hit them you get max braking right away. The adaptive cruise is wonderfull as far as setting your speed then it will adjust to traffic flow up to your set speed. It will slow down and re-accelerate when the traffic picks up, If the trucks ACC doesn't have the stop and go feature, it wont bring the truck to a stop, the DW's fusion has this feature, not sure if I like it, seems to stop too abruptly for my liking.

I also add that it beeps and provides max braking as wb6anp said, regardless of how hard you press the brakes. (Assuming that the system has calculated an impending collision, and subsequently warned the driver) If you don't hit the brakes at all, you will slam into the back of the car it was warning you about.

The F-250 SD does not have fully adaptive cruise control w/ stop and go, and therefore will deactivate below approximately 20 mph. It will maintain your speed above that, slowing down as wb6anp stated, and then accelerating back up when the traffic clears to your "pre-set" value. (Down to ~20 mph)
Did some more testing. It beeps and shuts off the cruise control at 12mph.
Why would it do this? And not bring the truck to a full stop?
I owned a 2013 Outback for a few years that had Eyesight. It was a wonderful thing to use in stop and go traffic. It would completely stop the car and when traffic moved, it would beep. Tap the gas and it would resume.
I've not tried Ford's ACC system, but I did try a BMW with radar based ACC and didn't like it as much as I did Eyesight.
I've found a sweet 2017 F-250 that has ACC. But this revelation has me second guessing the purchase.
Any way a software update will resolve this oversight? And any chance that software update will be applied to 2017's?
It does shut off at 12MPH and you can not resume its function until you reach 20MPH. I have no idea why they built it this way. Makes no sense what so ever. What's worse is it will slow to 12MPH on its own and then just beep and turn off. If a driver was distracted the truck would just drive into the car in front of it at 12MPH. I have the pleasure of driving 2 hours a day through San Francisco traffic and the ACC should make my life easy. But without the stop-and-go feature my right leg kills me after 2 hours of braking. My wife has a Durango and we went over 400 miles on her ACC with stop-and-go one time. FORD SDs are WAY behind when it comes to this feature. I would love to hear their reasoning on this set up.

Yes software could easily adjust this, but forscan can't at this time and ford probably won't due to safety issues.
I didn't add ACC to my truck cause sorry I'm not going to put my safety and my family in a computer to slow my truck down.
The computer checks the road 100 times a second. It is MUCH safer than you driving. The ONLY instance of a system like this failing was in a Tesla that the perfect circumstances happened to fall into place. Tesla fixed it so that circumstance can't happen again. BTW the guy that got killed in that car was watching Harry Potter on his iPad. Self-driving cars are the way to go!!

Ditto. This is just stupid. And I feel you on the leg thing. After I got used to Eyesight I used it 100% of the time. Regardless of traffic conditions.
Well, unless the sun or other visibility issues arose. To which it would disable itself and set off a loud alarm.
