Mine is always on when CC is active and although it is a great safety feature one mustn’t rely on it.
For instance a computer can act fast but only to what is happening not what is about to happen or how a braking event is not really that critical as the muppet in the BMW is so desperate to overtake the truck that he has almost missed his junction.
Balancing and finding a cooperative working environment between computer and human safety devices can make for a very safe truck, neither on its own is better than mutually masterbating the road ahead.

well thats that then…the oracle has spoken…the o/p was apparantly driving like a brain dead zombie fanny not paying attention and AEBS is completely useless as any normal professional driver would constantly be on the ball and never require any form of electronic aid whatsoever. …simple as that. would someone please forward this observation to folvo/scania/merc etc so they realise its a complete waste of time,and in future would they please just make trucks without it and sell them a bit cheaper.it serves no purpose other than a back door means of trialling driverless trucks for the nt too distant future when we will all be out of jobs and waffling dung on here…so thats is…no more to see here,move on,topic closed…on reflection,i think il flog my satnav on fleabay now,and see if i can revert back to using a lodestone…
Conor is the Chuck Norris of lorry driving. Conor Norris doesn’t brake, he makes the earth spin faster beneath him

Yes,it’s doesn’t just “go off” and slam the brakes on if it does then you should defect it.
Actually the systems fitted to the DAFs do exactly that. We’ve over 100 in our fleet and all of them do it at some point or another.
Common places:
Bridges over motorways
When going round a tight bend with fence posts near the kerb.
When approaching a junction with traffic lights where there is a light on an island in the middle of the road and the road bends to the left of it.
When a car is pulling into a petrol station entry sliproad on a dual carriageway and braking. It is clearly obvious they’ll be clear of your lane and a driver wouldn’t slow down at all but I’ve had the system whack the brakes on.
xichrisxi:
Basically you get an alarm first for 3-5 seconds which tells you of the impending danger,if you touch your brake before that 3-5 seconds is up then the computer recognises your aware of the situation and leaves the braking to you,
I didn’t last night when it slammed all on as I was going under a gantry on the A1M southbound approaching J44. Must’ve got maybe a second at the most.
People like you worry me. You think its infallible which couldn’t be further from the truth.

Never had one that was height sensitive but mine does recognise a vehicle decelerating on a exit slip as a hazard so will switch it off prior to event and then back on after, this falls under me reacting to what is about to happen mentioned earlier.
For height thing are the settings wrong as it may be using line of sight to far ahead.

We gave all seen the you tube clips with the Volvo or Scania trucks etc and have made some silly remarks about how dangerous they would be with certain loads such as steel etc to which I say secure your load properly and keep a distance and it will not move.
Yesterday afternoon heading up the New Jersey turnpike and coming to the split for local or express routes to the George Washington bridge, I chose the right lanes for local because it showed no delay as the left lanes for express showed 28 minute delay, I was doing about 65 mph when a Swift truck four lanes to my left suddenly turned 90 degree’s and drove across all four lanes to the local side, I was about to die … This wonderful safety system stopped my truck in about 50 feet without locking the wheels and left about 5 feet between me and the side of the afore mentioned vehicle. Believe me, the reaction of that truck saved my life.
I concur,Not quite as dramatic as your experience tbh,but had a divine intervention myself recently on a34 Bicester that saved me from a sudden stop coincidence with an empty flatbed,courtesy of my actros sensing a milliseconds delay on my part,so i forgive the many wanings and occasional lock ons it gives me day to day.
How did we and our forebears manage for all those years driving (a bloody sight faster than they go now) vehicles with nothing like the braking capability they have today, and most went through their whole lives behind the lorry wheel without ramming some bugger up the arse.
I asked one of the lads with a lorry equipped with this marvel how to switch it (and adaptive cruise) off when i have to use one, he looked aghast and said if i should have an accident with it turned off it would be my fault…no i won’t counter that point because i’m denting the wall with me head…

Aye but the roads weren’t a heaving with wall to wall aluminium in past times as today would be my riposte to that old bean.

DAF have told me that the the anti-collision AEB cannot be disabled as its part of the EURO 6 requirements. There is an "off" button on my 65 plate but it doesnt totally turn it off. So having street furniture “jump out in front of you” or bridge shadows “cut across your path” is a continuing problem. Doesnt happen everyday, sometimes goes for a whole week with nowt, then just as you start to relax itll throw 3 hissy fits in a morning. And yes, it has been defected and DAF say all is well.
Maybe it will save my life one day? Maybe itll lead to 1,000s of drivers all having premature heart attacks brought on by the stress of waiting for the next false alarm? ACC in DAFs can be (in mine anyway) turned into conventional cruise control by holding down the button used to increase/decrease the separation distance. And bashing your head against a brick wall is not necessary, if you don`t attach your seat belt, as the EAB will automatically push your head against the windscreen.

Ironically Pat stated as being being an old school night trunker would have been expected to know better than go storming through a dodgy split in traffic at 65 mph.
i think people are getting adaptive cruise and AEBS mixed up.
AEBS and how it works is dictated by legislation. It HAS to give a warning before braking. I can’t remember the exact figures but it is something like first warning at 1.4 seconds and another warning at 0.8 seconds - then 0.8 seconds later it’ll brake. If the driver takes positive action it won’t brake by itself.
In my experience drivers who seem to have problems with the AEBS and false alerts or unrequired braking need to consider their driving style or defect the system. If the driver has read up on how it works they will understand the circumstances in which it would alert and so avoid them which will in turn give a safer drive all round.
The AEBS systems will be life savers but it does worry me what happens to non-AEBS trucks driving too close behind or unsecured loads.
Of course it can’t be many years and all trucks will be merrily following each other in a ‘platoon’ and the driver not in direct control most of the time.

The false alerts I get on my 65 plate DAF are pretty much instant. Red collision icon, bleeper, and full brakes. One and a half seconds warning? I dont think so. And anyway, what action should a driver take to avoid a phantom? Always gone off after a second, but always very sharp braking. I dont think its my driving style (yeah, who ever does!) as the system will kick in on a road empty of traffic, but with an over pass or maybe a road-sign near the road edge. DAF have checked it out and said all OK. The other drivers with sister vehicles all report the same trouble. Im sure you`re correct about the theory of how it should operate, but my own experience shows differently.
Well all i can hope is we don’t get any winters any more.
The thoughts of this safety system jamming the anchors on when it sees something or nothing on a nicely icing road fills me with confidence.
Rare days like that are, but not rare are those early winter evenings where previously salted roads attract the damp and turn that salt residue into a fine lube, heavy traffic doing its thing and our errant finest euro 6’s (of which there will be thousands) likely to chuck the anchor out at any moment, reason or not.
Yeah can’t wait to get mine.
I drove a 65 plate DAF CF for Iceland a few months back. Came to a right turn and as soon as the unit made the turn it slammed the brakes on. As I made the turn I assume it saw the parked car I needed to just miss and was probably thinking I was about to hit it.
A decent driver does not need their truck to think for them, its a bloody hindrance.
The actual EU legislation is quite complex and describes how the system must work, how they must be tested and even covers false alarms if I remember rightly, but this only applies to trucks made after 1/11/2015 and although some older trucks have AEBS they are not necessarily to the same standard.
As far as I know, braking should not take place unless the appropriate warnings have been given. 1.4 seconds is about the average time it takes a human to react and get the brakes on. Some of the warnings can be ‘haptic’ so perhaps a vibration or dip of the throttle, but as far as I know the 1.4 and 0.8 second warnings are lights and buzzers.
Get onto DAF and get detailed instructions for their system, then compare it to what happens and defect it if it is faulty.

Interesting reply. But, having defected it, or them, and been told that all is ok, how can a driver with no access to test equipment go on? As you say it is a complex bit of kit, and me saying "it aint right" isnt gonna carry much weight.
I do think it is a good idea, but was it Douglas Adams who said “technology is what doesn`t quite work right yet”?

Don`t worry the anti-skid technology will turn the brakes off so correcting the skid you wer… oh, the truck …was getting into…

Yeah thats the bit, you and i both know the anti skid stuff aint worth a pail of cold ■■■■ when ice gets added to the equation, you don’t brake in those conditons unless you need to because even a momentary unplanned lock up of the wheel on ice and all that carefully nurtured control is history.
Let alone the fun of wondering as you gingerly slither along when the next full emergency brake will happen…probably find bomb disposal experts would have the nerve for it
Its just more tripe from the one size fits all mindset, because some drivers are numpties who shouldn’t be allowed anywhere near a bloody lorry ever and carnage has resulted because they were, all must now be tarred with the brush.
