Does TAAC use regenerative braking when decelerating?

My Model S is at 207,000Km still on its original brake pads.

I think that an update in the last 12 months actually increased regen on TACC to levels above the normal levels that we get when driving manually. Possibly even to the levels you get in Track Mode. Certainly pretty harsh at times.
I average 15,000km/year. Hopefully I'll still be driving and on my original brake pads in 13 years!
Thanks. I never expect to need to charge beyond 90% so battery SOC shouldn't be an issue. The regen rate appears to be higher when using TAAC than when driving manually. In other words, when TAAC is braking, say from 80kph approaching stopped vehicles for example, the level of braking is higher than if I were to simply take my foot off the accelerator.
I've noticed that TAAC often brakes later than I would if driving manually. I've wondered whether that's a limitation of the automated driving system picking up the need to brake later than a human driver would or a strategy to maximise regen efficiency.
I‘m not sure about the optimal regen rate. It is an interesting point. If I‘m in a situation where I think the car will break late, I usually disengage TACC/autopilot and manage it myself. Mainly for the sake of comfort, but also to give following cars more time to see me slowing down.
Yes, I have wondered the same and have come to the opinion that it probably is for maximum efficiency, why stop an almost 2 tonne of inertia unless it is needed. It does cut it very fine sometimes.
yes I agree, but tesla don’t agree as they continue to gift cars with phantom braking…today I was going past a parked truck in tacc (not autopilot) so I was steering. I was around 1m clear of the parked truck but the car didnt agree so it slammed on the brakes. Horrible crunching grinding sound came with it. Fortunately no-one behind me.
Yes, it is very afraid of passing trucks at the moment. I wonder if it interpreting them as traffic queues. There was some discussion about trying to avoid having cars suddenly encountering stopped traffic obscured by a longer queue in one lane.
Nevertheless it is really a problem with the current driving model.
It has never liked passing anything in the same lane, so if there are parked vehicles in the left lane you can't cruise in the left lane past them. Same with cyclists in that lane.
Thats not entirely correct. There were plenty of cars parked to my left, it was only the truck it had an issue with. In suburban Adelaide most parking is to the left of an extra wide left lane. It isnt marked.
This is for tacc only not autopilot.
