I too think you are right...the distances (close, medium, far) seem longer than what they should be. Does your FCW seem to work right? I wonder if those distances are off too? Or I wonder if since you are not in USA maybe the whole thing is programmed differently?

That's the ACC set speed limit, the 120kph is the speed limit warning.

The FCW works fine, it only starts going nuts when I'm really close to a car at high speeds (overtaking etc). But that's a few feet away from the bumper.

I can't confirm if my ACC is acting up until I see comparison pics. I'm currently trying to find youtube videos and online pictures that show ACC along with speed and settings, it's the only way I can confirm. And of course anyone here that can help me out too !

**edit** For any new reader, please check previous page for more info about my concern.

Re: Adaptive Cruise Control - Car distance ?

My ACC when set to one bar is about 3 car lengths from the car in front of me

the first pic seems a little far but don't know if speed plays a factor. i tested the three distances today at 60mph it is about 3 car lengths, then 5 car lengths, and about 7 car lengths for closest to farthest settings. i will try driving at slower speed to see if there is a difference this weekend.

Re: Adaptive Cruise Control - Car distance ?

After more testing, I came to realize that the distance is exaggerated (like the first pictures I posted) because the car slowly tries to catchup with the car in front of it.

When travelling at a lower speed and constant acceleration, the distance is merely 2-3 cars apart. Furthermore, travelling at a higher speed while the car in front decelerates, the distance goes back to 2-3 cars apart from a further 3-5 car distance. I think it's a mechanism to avoid high speed collision and give the controller some time to react, not sure.

Here is another pic while testing. Distance is about 2-3 cars apart (use white car for measurement).
Note : It seems like relative distance plays a role in images, as cars appear closer in reality when compared to these pics I'm taking.
