2020.32.3: Way too fast through curves

[LowlyOilBurner]

Can anyone else confirm that their car now sucks at slowing down for sharp curves while on TACC or AutoSteer? Model Y here on 2020.32.3.

NoA also disengaged while making a lane change onto an on ramp that normally it does perfectly. Red steering wheel “take over immediately” flashing.

I’ve read of the regressions in updates, sucks, but looks like this is what’s going on here.

I posted this in the 2020.32 thread under the software/updates section, figure it’s more relevant to make a thread here about it. Thanks!

That actually sounds good to me. Tacc is a cruise control, i expect it to keep its speed unless it will hit a vehicle in front. I'm actually tired of jt slowing doen for plenty of reasons. Noa on the other hand should slow down when necessary obviously.

 

[LowlyOilBurner]

Well, in moderate curves it seems better, not hugging the left lane marking as much. I’m talking on sharp curves, seems way too fast for me.

 

[GtiMart]

I guess it might be a matter of taste / driving style. I vastly prefer a cruise control that keeps its speed. Autopilot should indeed adjust its speed, and most certainly NoA. To what speed does it adjust depends on the driver. I would love an "agressivity" setting like there is for the NoA lane change. I would have it to madmax I've been finding recent updates more cautious in general. For example, the forward crash alerting, even on the late setting, has been screaming at me more recently, to the point I've had to turn it off.

Tacc is a cruise control

I love that TACC (not just Autopilot/NoA) slow down for sharp curves.
TACC == Traffic Aware Cruise Control, to me "traffic aware" means more than just aware of other cars.

I've also noticed that the car starts to slow down for curves a lot later than before (at the last minute) and also goes through the curves faster, if for some reason it does not slow down it leaves little time to react.
This makes me less confident because, at least here in Europe, now it triggers the warning about lateral acceleration in curves that previously was doing without problems, that is particularly bad specially if the roads markings are missing or washed out since it tends to drift to the middle of the road instead of keeping in lane.
Model S updated from 2020.28.6.

You're abusing the definition of traffic If you lookup the definition you'll see that traffic is about cars, pedestrians etc following a route. Traffic aware cruise control should be aware of that, and that's about it. If you want a system that drives for you, taking into account the road markings and speed signs, that would be autopilot (the name is actually not correct as it's just an assist) or NoA.

What about "traffic pattern"?
I understand that most manufacturers treat TACC as cruise control with car detection -- that doesn't make it better or right.
Maybe Tesla should call it Smart TACC

Someone disagrees with me quoting the dictionary? Wow... Ok, I'm out

I drove some twisty country roads this morning, it’s not as bad as I thought. AP did a good job. Seem the spiking of the brakes at the crest of a hill is gone, it’s doesn’t slam them on, much much smoother now. I guess it just sucks on slowing down on my road?

Yes, this Curve Aware Cruise Control feature is either gone or way, way too aggressive. I think it is gone.

I live in the hill country with lots of curvy roads. It used to work very well if slightly timid.

We need this feature back with a control so users can adjust the aggressiveness to their liking. I would actually prefer that control replace the car lengths knob which I rarely use.

Funny to read this. I actually keep my foot near the accelerator pedal when corners come up because I know the TACC will slow down way too much for my preferences.

It seems AP has been alternating between two variations of curve behavior for the past year or so, one that brakes and one that mostly doesn’t (current one). It doesn’t feel like either version has changed much, but they just almost go back and forth every couple large firmware versions. Anyone have an idea why?

They probably want to see how often drivers override the behavior to test the threshold that has the fewest / satisfies the most drivers.

I actually like that it’s going through corners are near full speed again. Last few updates have caused it to slow dangerously down, to a point where it’s too slow.

I generally agree with this, but honestly it would sometimes be useful to have a standard cruise control with no safety features or possibly just radar based forward collision warnings!

I finally tried 32.3 last night and saw no difference through a few of the curves I’ve driven multiple times... still slows down to at least 5-10 mph below the speed I’d pick if I were driving through the same curves

... Anyone have an idea why?

Because they are listening to complaints on this forum?

 

[3gmcintire3]

There seems to be different desires of how this cruise control should work. Some are saying it should not change speed at all, others that it should but go thru the curve at a fairly high speed and others wishing it would go thru at a lower speed.

Can we have some user control of this feature?

 

[LowlyOilBurner]

2020.36 is no better. Some curves are way too fast, others, it handles fine.
