Phantom braking to be investigated
- Thread starter Alex987854
- Start date
the autopilot in general is perfect on motoray.
although all I really want is
a) be able to disbale the ding dongs completely (joey mode not quiet enough)
b) when I change lanes it re-enables automatically, like with any other lane assistant system on all other manufacturers.
ideally - a+b, but at least 1 thing, please.

Well, as discussed, none of us in the UK have driven one anyway...
For now, this works to tell the difference, I believe. Tesla Vision minimum follow distance has apparently reduced from 3 to 2 via software updates since Tesla Vision cars started shipping, however, and it seems eminently plausible that in a future software release these differences might be eliminated.
It would be great to have a reliable way of distinguishing between radar-based and Tesla Vision vehicles, that isn't dependent on vagaries of autopilot that can change from release to release. Unfortunately, it doesn't appear that one exists.
For now, though, it appears that Tesla Vision is limited to recent (no radar) cars in the US (and maybe Canada?). It hasn't yet, as far as I know, rolled out to any US cars that originally shipped with radar (except for the special case of cars that have opted in to FSD beta). My personal guess is that it will be deployed to the legacy (radar-equipped) North American fleet before they start to ship radarless Tesla Vision cars in other markets...
camera-only is known as Tesla Vision. As discussed in other posts, it's only in the US. All UK cars still use radar (at least, as far as anyone knows).

ok... but breaking is issued by camera - it notices something odd and brakes. i.e. on t-junction car is a bit more into the junction, and although stand still - car thinks that it is moving into junction and brakes. happened today
I guess it's because Tesla is always in the news, but how come the BMW i3 cruise control was never investigated for phantom braking?
My i3 is guaranteed to phantom brake on a motorway journey, so you have to cover the accelerator. Shadows, bridges, sun, rain... Oh and on a dual carriageway if there is a vehicle in a lay-by.

I think in part it's because the Model 3 is a victim of its own success. BMW simply don't sell anywhere near enough i3's to rack up significant numbers of complaints for the problem to be on the NHTSA's radar (no pun intended).

I drive an i3s for three years and thought it was just standard cruise control. Admittedly didn’t do a lot of miles in that time <9000 but never had a single ghost event.
I’d be happy with a standard non “intelligent” cruise portion on the M3. In my opinion fwiw, the sensors, the software and the British public on British roads are decades away from FSD/ EAP working properly.
Does the i3 rely on cameras alone? I ask because my last two BMWs had adaptive cruise and the system was essentially flawless, unlike the TACC in my M3.
The simple fact remains that Tesla have made outrageous claims for their system in the past, and not every Joe Public has kept up with their downgrades. Also opinion differs on what constitutes phantom braking. Those who have only experienced a 'bit of a slow down' don't think it matters. Those of us who have had the brakes slam on full at 70mph (for no obvious reason) had to throw their trousers away. Human reaction time can't beat a machine.

The adaptive cruise, lane keeping and lane changing on my X3 has been flawless in the year I’ve had it. It once briefly started to phantom brake as I went past a lorry but it quickly sorted itself out before I could put my foot down to speed up again.
Bmw lane assist was very good. I just wish that I didn't have to re-enable lane assist (aka auto pilot) every time I change lane..
Anyone knows the hack how to have it running all the time without purchasing enhanced autopilot?
It is the i3 ACC I am talking about, so not just the standard speed keeping one What model year did adaptive cruise control get better? - BMW i3 Forum
Of course if only BMW did OTA updates to improve it... oh wait that's why you have to buy a new car

OTA updates on Teslas have done nothing to improve phantom braking. Buying a new Tesla won’t help either. Tesla are clearly incapable of fixing it.It is the i3 ACC I am talking about, so not just the standard speed keeping one What model year did adaptive cruise control get better? - BMW i3 Forum

Just a quick update on the TACC issues I mentioned. Last night, I was on the A14 east bound going across the top of Cambridge and the decided to cut the maximum speed on its own with no user intervention from me as I mentioned in my posts in this thread. It happened at exactly the same place as it did on the last time I went through this stretch of road. As I mentioned earlier, the speed limit symbol doesn't change but I watched the TACC speed cut dramatically on its own for no reason and you have to manually re-set the speed back to 70mph.
A couple of google maps pins of where it happened:
This one it went from 70 to 40 Girton · Girton, Cambridge CB3 0JN, UK
This one went from 70 to 30! 102 A14 · 102 A14, Milton, Cambridge, UK
The ID.3 ACC does the same thing. It could be out of date mapping info in the database from a temporary speed limit during roadworks, or just a glitch in the lat long & the car thinks it's on a different road entirely. There are a handful of spots my ID.3 will always slow down seemingly randomly.

2019 VW Tiguan Tech R. Phantom braked so much I stopped using adaptive cruise control and the worse thing is that stomping on the accelerator would take around ~1s to repond and a further 1s to start accelerating. It was too dangerous to use at motorway speeds. It had two replacement cameras in 12-months but it never went away. I sold it.
I love adaptive CC but it sounds as if I’ll get it with the MY. I can’t imagine that 354 complaints and no fatalities in the past nine months will make them doing anything. (According to one news website)

It's really not that bad. Actual phantom braking is realy a thing (literally stamping on the brakes at 70) but pretty rare even on these forums.. unexplained slowdowns more common due to shadows, lorries veering onto your lane, that kind of thing, more common but even then I've been up and down the country and despite the occasional WTF moment not something that's worried me.
That leaves mapping errors.. which depends where you are. I've not come across those recently and not sure they really count as phantom - they're completely predictable when you know where the error is.
