Aggressive Emergency Braking?

[Derektsla]

I’ve owned a Tesla for seven years. Today is the first time I’ve ever had automatic emergency braking kick in on my cyber truck (or any Tesla). It caught me off guard because I was steadily breaking harder with plenty of room between me and the car in front of me, but apparently the truck didn’t think that was enough and pulled the pedal right out from under my foot and slammed it to the floor. I didn’t have an “oh crap” moment because it stopped me well before the car in front of me. I’m 99% sure my level of breaking would’ve stopped in plenty of time, but maybe the truck is more cautious due to its weight or distance before the vehicle in front of it. No FSD or Cruise was active during any of this. I was under braking slightly to avoid tossing things around my bed, but that went out the window when the truck took over.

Has anyone else witnessed what they think is more aggressive emergency breaking on the cyber truck specifically?

What's your early warning and follow distance setting? Have video of the incident?

Mine doesn’t seem to like stop and go highway traffic on the interstate. Seems to get on it pretty hard and stop way too closely to the car in front of me instead of casually braking with plenty of time. I’ve reported this quite a bit to Tesla so hopefully someone or AI listens to those recordings.

Other than that this has never happened. Just seems to brake way too late even with a completely stopped car on the highway 200’ in front of me.

I think Medium. I have not looked at the video. I’ll take a look at it soon. It did make the beep when it saves a clip after, so I assume there is one to watch.

I agreed that FSD brakes late a lot of times. I often disengage to brake sooner and send that feedback to Tesla. This is different than that, so I assume it’s different logic.

I never hit the brakes, regen usually more than enough to stop quite quickly.

Yes, over 300k miles on MS/M3 never had an issue. Day 1 of CT ownership I let it roll a little fast toward the car in front of me at a light, planning to add brake in time, but then WHAM full stop, everything went flying including my drink, NOT a fun experience... but hasn't happened since, not sure if it was a bug or it subconsciously taught me not to do that anymore.

My experience driving down the Interstate is that the the CT brakes abruptly many times, apparently due to changes in the color of the road pavement (as near as I can tell). This is an 80 mph to 50 mph abrupt deceleration, and really puts all the passengers on edge. Very unpleasant, sometimes happening once a minute.

Once a minute? O-o

So, every mile and a half?

If one has not had an AEB event yet. It seems like you did. Welcome to the party. I have had many. It is like a five point harness lock up or feeling like falling till a harness catches you. Be thankful. It really has saved my ass many a times. Often on flat top tow trucks or items sticking off back of a truck. Has been as small as 2 inches or sometimes feet to impact.

I drive like 50k to 70k a year. So crap happens.

AEB has been added to potential side impacts if it can see a cross mover. All it is trying to do is minimize impact. Can't always make the stop.

That is phantom braking. Not AEB. If it was AEB your passengers experiencing it once a minute would be peeing pants.


Also AEB shows in alerts. If it isn't there it wasn't AEB. It does save a snippet as well. Not sure if Tesla puts this in the accident avoidance stats, as mine were off AP or FSD over the years and cars.

Happened once on the MYP crossing an intersection. Good the passengers at the back had belts on.
