Adaptive Cruise Control Questions

3388 Views 8 Replies 6 Participants Last post by  Loboc
I haven't found an answer to this and would like to ask the forum. Driver's Confidence Package 2 gives "automatic forward, low speed automatic braking" with forward collision alert. I believe I read that was 31 MPH or less.

ACC (Adaptive Cruise Control) gives "Full Speed Front Automatic Braking"

Here is the question for a car equipped with ACC BUT not having cruise control on. If I am driving 45 MPH or 55 MPH and the car senses I might hit the object in front of me, will the car try to stop itself? I can't seem to find any answer. Does anyone know?

Based on my experience NO. You must have ACC ON before the car will brake at speeds over 31 MPH. It does work, it's not as smooth as a human, but once it locks on to car you are following it will stop the car to a dead stop if the car in front of you does so.

Re FCA and FAB all I can say is I don't think I have the guts to test it. I have gotten many FCA's and have always gotten to the brake pedal before the car has reacted. I guess if I were really not paying attention it would engage. But to sit back and hope it works is not human nature.

I wonder if there is some test we could conduct in a parking lot to see how it works. So far I haven't seen any YouTube video's with a Volt. There are a few with Tesla's though.
Everybody is still too chicken.

BTW - Have you SEEN the FCA come on? GEEZ!!! It has an HUD that broadcasts 6 superbright LED's across the windshield while beeping at you. It WILL get the attention of anybody with a pulse.
Jarring is how I describe it. The BEEPING could wake the dead.
