Radar / Adaptive Cruise / Emergency Brake - Questions and Issues

[GolfVII]

1. City Emergency Brake only works below 30 km/h.
Those crooks were clearly driving faster than that as they tried their getaway.

2. The object you're about to hit must also be moving. Another ad fail.

1. True you can see the blurred speedo go over 40km/h...

2. It was my understanding the ACC does not detect stationary objects at all and the ECB when travelling under 30km/h will stop before hitting a stationery object. I guess that is why you can not set Cruise Control under 30km/h?

you are correct this advert is a fail

while travelling with ACC activated I had a Merc driver pull-out from a truck going 40km/h up a hill to pull in front of me doing 100km/h car alarms went off but no breaking etc ( I think or I reacted to quickly) lucky I was able swerved and applied breaks other wise I would have had a new bonnet emblem.

I'm so tempted to try driving in to a box in a car park and see how this really works, should have asked to borrow the box from my new fridge when they delivered it doh! delivery guys would have been like WTF is he doing lol

It's saved my a$$ or should I say front twice now from idiots doing illegal u-turns. Works a treat. Cars turning left can set it off but I keep it on for the extra safety it adds.

Does anyone know how this (or Active Cruise Control) works on the manual models? Surely they would inevitably stall

I just had another watch of the iconic Volkswagen ad demonstrating City Emergency Brake


Volkswagen Golf - The Getaway (City Emergency Brake Technology) - YouTube

and suddenly realised there are two things wrong with it:

1. City Emergency Brake only works below 30 km/h.
Those crooks were clearly driving faster than that as they tried their getaway.

2. The object you're about to hit must also be moving. Another ad fail.

Time to call the ACCC?

The system will brake to a stop at speeds up to 30kmh (both stationary or moving object)

Between 30-80 kmh, the car will warn about stationary objects, but will not brake.

Between 30-200kmh, the car will warn & brake with moving objects.

Full throttle will override any assist systems in place.

The ad is misleading tho.

I can't remember where I read this, but Front Assist & City emergency braking are different between AUS and EU spec Golfs. The EU ones have a camera mounted at the top of the wind screen. This camera is primarily used for lane keeping assistance however, it also increases the maximum brake pressure that can be applied by the car, increasing the effective activation speed for Front Assist & City Emergency Braking.

AUS spec Golfs don't have the camera fitted as part of DAP. This reduces the effectiveness of the system when compared to EU equivalent.

The ad is misleading tho.

And potentially dangerous if an Aussie ever decides to emulate the ad

I think they call it natural selection

Hi,
Today on my way from Canberra to Sydney I tested front assist. I truly enjoyed it. I tested all distance modes. Perfectly working. When I indicate n come to right lane it accelerated nice n smooth. Cars cutting me when my ACC is set to 110 I could see the front assist detecting these cars and slowing. Another one I found today is trucks slowing down rapidly in uphill and front assist slowing my car in full control. And when they speed in downhill it picks up speed smoothly.

City emergency braking is worrying I thought I could test that when my car is moving at 20km/hr. I sense brakes are preparing but i couldn't wait till it brakes. Distance between cars is less than 2 meters.

I will try with big card board box in an empty car park in the night when I get back home just to confirm it is working in my car. I needed that confirmation. I will update once I did the test.

ACC is great, I'd never buy a car without it from now on! Correct me if I'm wrong but I believe front assist is different to ACC in that it is VW's collision avoidance system. I've had front assist start beeping at me two times, once when I was entering a tunnel and I guess it must've thought the ceiling was a wall or stopped car. The second time was at a stopped car turning right just before I went into the left passing lane.

Has anyone had front assist brake for them yet? Love to hear how it goes.

I personally haven't had it full brake for me. Had a friend who "used" it and described the experience as pant ****ting.

Apparently at 30km/hr, the car doesn't leave much room once stopped. Cuts it very fine!

I've had front assist brake for me. Had ACC set 90km/h coming around a bend sun in my eyes and car in front decided to brake hard and turn into a driveway. My GTI braked really hard and I was able to avoid a serious crash. Scared the crap out of me actually.

Love how the system works. Wish my Amarok had it as its my daily.
