Radar / Adaptive Cruise / Emergency Brake - Questions and Issues

City Emergency Brake

Hi all

Can someone explain in more detail about emergency brake assist that comes with drivers assistance package?
From what I know, it brings you to a stop if you are below 40kph, or is it 30kph?
What happens if your going faster that the allocated speed? Is there any warning or is the option then useless?

Also, how does VW eba compare to other cars eba?

The car will warn you to apply the brakes before it applies them. I'm not sure about how the speed limits fit in.

Disregard my post. Wrong info.

Haven't picked up Mk 7 yet but if it's like my Merc it alarms if it detects a dangerous closing speed and primes the brakes, tensions the seatbelts and once you touch the brakes will apply max braking before your foot could. At slower speeds I think it actually brakes for you. There is a good video, I think it's Fifth Gear. Comparing a Merc and VW and another. The VW is the only one that doesn't hit the " object" in front !

My Caddy Maxi Life has it.

Basically, if you apply the brakes in an emergency, then it will take over and apply them as hard as it can to stop you as quickly as possible.

This requires you to really stand on the brakes, at which point Emergency Brake Assist will take over and apply the brakes even harder. There are also other parameters that come in like the speed you are travelling at, and how long you have applied the brake pressure for. This is to avoid unnecessary emergency stops.

For most people, it is unlikely to activate. You have to apply the brakes so hard that you leave finger impressions in the steering wheel.

Oh, Mercedes Benz brought it out in their cars many years ago and ended up disabling it because it was so sensitive that it triggered far too easily and drivers ended up with new boot emblems just stopping for traffic lights.

There is some confusion here guys.

City Emergency Brake is what the OP is referring to. It uses the radar from the radar cruise system to detect an imminent collision, and jumps on the brakes to either prevent or reduce the severity of an impact. This feature is only found on vehicles with the radar cruise as part of the Assistance Pack.

Brake Assist detects when you have applied the brakes in a rapid 'emergency' way, and increases the brake pressure to a level beyond that you would be capable of by simply exerting more force on the pedal. This reduces the delay between when your foot touches the pedal and when the car actually starts heavy braking.

Can vouch for the City Brake Assist in the Passat at least. First week I had it l looked away for a sec and a car had almost stopped in front of me. Suddenly all hell broke loose Beeper goes off, brakes nearly put me through the screen and we come to a shuddering halt.

All with my foot still on the loud pedal.

Car has the full driver package. Mine apparently doesn't detect a stationary object according to the manual, just slow moving ones.

Newer models like the 7 are probably better still

Sounds a great option to get DAP which includes the Adaptive Cruise Control - a lot of useful and safe technology - I like the idea of these braking systems...........I want DAP I want DAP!!

I reckon this is the City EB you meant to link to:

Pretty sure our Golfs don't use lasers.

That's what the Passat has. Front assist with City EB Definitely works well

Does having the City Emergency Brake fitted as an option have a positive effect on insurance premiums? ie two otherwise similar MK7s, one with Driver assist package the other without. If so it might be worth considering for a family member who is the market for a MK7.
I recall a top Gear episode reviewing the MK7 R or GTI and Clarkson mentioned that in the UK the inclusion of CEB markedly reduced the premium. Was he serious or was he having a lend? I am guessingAustralian insurers will see it as a means to reduce their risk without passing on a cut to our premiums.

Didn't make any difference to mine When I put the model in it listed all the factory options I just ticked the ones I had and it gave me a price

It didn't make any difference to mine either. Maybe when lots of cars have this feature they will simply increase premiums for the remainder that don't.

Who wants to test out Front Assist and City Emergency Brake.

Hi All!

I've been watching some videos of the FA and CEB in action. I want to give it a go. It looks like fun!

Anyone interested in helping to figuring out what sort of test rig we could put together and then finding a car park somewhere

Cheers,
