Autonomous Emergency Braking - any experience?

Post by FairlyOldGit » Tue Oct 18, 2016 11:38 am

Has anybody had to call on the Autonomous Emergency Braking ? and if so I would
be interested to know how it worked and under what circumstances it kicked in.

ISTR that Jaguar weren't 100% that it would avoid an impact.

p.s. I have no intention of going out to test it myself !

:lol: Nope, but I've wondered the same thing. Somebody needs to test it out on a cardboard box... volunteers? Anyone?

Only happened once to me.
Turning into a car park with over hanging bushes and the stupid car must have mistaken one for something more substantial.
Brakes banged on briefly with a graunching noise and a couple of beeps then released straight away.
I had words with it after and it's never happened again.
Stupid cat.

After the salesman explained to me how it works whilst on a test drive, I asked if he could try and run me over when we got back to the dealership.

He refused because of something to do with health and safety.

I was approaching a right turning coach in an outer lane and estimated I could easily swerve around it using the nearside lane but the AEB thought differently and applied the brakes. I continued to steer into the nearside lane with brakes juddering for a second until the way was clear.

Interesting comments already!

I wonder what the 'graunching' / 'juddering' on the brakes was down to ?
I assume that neither of you PhilB or robertW had any problems with brakes under normal use -
could it be some form of ABS kicking in?

Phil what sort of hammer did you use when you had words with your car? :lol: :lol: :lol: :lol:

Juddering/graunching is indeed abs. XE hasn't done it so far, but i've had that experience in previous cars under heavy braking!

I noticed in the manual that the system doesn't actually intend to stop for mere cardboard boxes (or, perhaps, human guinea pigs). It says it's designed specifically to detect "real vehicles, plus other certified Euro NCAP target objects".

But if the objects are targets, why stop?

ash,

Overhanging Bushes must qualify as 'a certified Euro NCAP target object' judging by PhilB's experiences !

That would explain why it also says "It is recommended that the AEB system is switched off when driving off-road".
