Title: SBS Smart Brake Support- not working?
Post by: Madasadad on October 03, 2017, 09:11:20 pm
My car seems to have SBS support, however when i set up a cardboard box barrier to test the system, in every case and at all speeds, the system failed to work/ intervene.  Is there any way of verifying that the system actually works?

I have the second generation car, so had no idea that such tricks exist in the new 6. I found online some videos and it seems that it had to do with the settings.

First I found this:

Have you played with the distance settings?

Then I found this from the CX car:

This is impressive.

Has all the fails you explain but then he sets the distance and it works with the same carton test you do while previously it did not.

I would play with the settings and if it does not work, I would visit the dealer to ask them to demo/check it for free.

I know there are many conditions (grey areas) under which the system will not work, plenty of information in the manual.

I had a bit of a "situation" last week. Parking the car in the NCP multi-storey place, pulling up to the ticket machine, yellow barrier ahead of me. All of a sudden car stops, honks and displays a message about the emergency breaking.

Bit weird, wasn't going quickly or unable to stop in time. Felt like the engine stalled, honk was a funny accent too.

This is what to expect when the system actually does work...... hope this helps in the slightest.

Hi
I think you will find if you tested against something metal it will work better if it works I asked the dealer to show it works in my car and he drove at a builders skip and it stopped fine but having an auto the car then wanted to drive of again towards the bin but at tick over speed.

I would use the two Mark 1 eyeballs you were born with and a bit of common sense.
If you cannot fit two 52 seater coaches between you and the car in front, then you are too close, this why shunts happen.
You have a driving license which means you are responsible for the safe  operation of the car on the road, not a bunch of electronics, you will be falling asleep at the wheel next.
There were such things as ABS  assisted collisions  when that came out, looks like the same will happen with SBS.
