Yeah, they detect blurry lens, sunglare, wiper in view, blocked lens (triggers on repeater cams in my garage for example). This (the second example for sure) is not a valid sign and nobody should be expected to obey it.
The first one isn't even a stop sign. It is neither the right color nor the right font. If you get a ticket for running that one, you might motivate me to go to law school and pass the bar to defend your BS ticket!
FYI, this is the sign in the second picture I was thinking looked like a stop sign and would be partially blocked.
If they notice that before one date all measurements agreed with the map and after a date they disagree, they can remove the previous mesurements and add the new and then remake the map for the local region. Map making is pretty robust to incorrect measurements nowadays, see for example Olsen’s proposal: (see lesson 20) Robot Mapping - WS 2018/19 - Arbeitsgruppe: Autonome Intelligente Systeme For how to update a local map, see lesson 16. Ground truth, which they use to verify the map making process, not to make maps, likely comes from a lidar and RTK GPS based map maker. HD maps is an extra sensor for the system. It decreases uncertainty and adds robustness. It allows you to see when your vision is covered etc. And if your camera goes blind you can still know where the lane markers are as you use radar to position yourself in the map and slowly drive to the side and stop.
Great answers @heltok thanks so much! I particularly see the value in having HD maps if the sensors fail and the car needs to make an emergency stop.
Along the same lines, there’s a stretch of highway on my way home where the right lane merges. Right about where the merge starts there’s a “Lane ends” sign above. The maps are very detailed so it knows it’s a merge lane. It also knows no lanes have signs over. What it doesn’t understand is that the merge lane has a sign over it. My car will come to a full stop when it gets to that sign (I’m assuming cuz it thinks it’s an obstacle). It’s been happening for months ... at least since NOA was released. I’d think that there’d be a priority in reconciling HD maps vs reality that “Stop or you’re going to die!” map behavior would be quickly reconciled with my very real ability to drive through perceived hazard and continue home.
I recently noticed that on my daily commute, Autopilot (or Autosteer) suddenly (overnight) started to drive much better; less weaving, didn't try to take a merging lane anymore etc. The firmware has stayed the same (2018.50.6) so it must be an update in the maps, right? How old are the current AP maps in Europe at this time?
I've seen the same in Ukraine. It looks like new maps released. And I was really surprised when was finding NoA trigger in the Autopilot menu! I activated it, checked that if the route is outcide of city it offers to use NoA but haven't had a chance to check how it works. But anyway I didn't expect NoA in Ukraine soon! Nice surprice!
Yah, the newer the more reliable. So a disagreement such as this: «HD map: Stop sign, timestamped 3 minutes ago» versus «NN: Splattered bug on windshield, no visual on any stop sign» should perhaps send some brake command (unless «NN: Semi truck at full speed 1 meter behind you»). Or...?
Very interesting to se NOA on somthing else than model 3 in Europe! What firmware are you running? Did you get updated release note also with noa desvription? Noticed big downloads?
That, plus weighting by road/road type. Perhaps low traffic volume roads should be treated differently?
It was a really big surprice for me! I got 2018.50.6 few weeks ago but there wasn't any notice about NoA in the description. The same as it was in December when I got 2018.42.1 and 48.12. There was neither notice nor NoA itself. Now there is a notice about NoA but in a history of descriptions for previous versions. Pictures are under the spoiler: Spoiler: Version notices I noticed a download of 5 GB via wifi last week. I think this is new maps but as you know it doesn't show any messages after a map update.
Sorry if I missed it... now that we can see map version on the in-car software tab, do we know how to decode the version number? Are we tracking versions?
Good questions. Current version in my AP2.0 X 100D is NA-180906-1605 North American version dated 06-Sep-2018 at 4:05pm as a wild guess
