AP2 AutoSteer swerviness...??

[Lou gagna]

17.17.4 definitely helped: It basically eliminated the back and forth wandering on straight or nearly straight road segments. On curves, I still find that it navigates through curves by mild jerks of the steering wheel as opposed to a smooth sweeping motion, but it's more "correct" than before (e.g. rarely gets close to the edge of the lane and makes you nervous)

Mild jerks seem to be due to the software rigidity to keep the car right in the middle of the lane, versus a human driver that will go to the interior limit of the curve at the center point of the curve, in one stable arc of driving.

Still trying to find all the hardware/software versions & updates. MX 100D, delivered 31Mar17 and have added 3,400 miles to our beauty as of 5Jun17. The latest wifi update about two weeks ago helped significantly. Before, we could not autosteer on WA SR3 at all Now we can. SR3 between Shelton and Allyn is swervy and varies in speed from 40 mph to 55 mph. Beautiful drive by the way. It is two lanes, one in either direction. Near the turnoff to Harstine island the lane separation and line painting was done by Buba under the influence. Lines are blurry and in some cases overlapping:-( Our MX when approaching from either direction swerves towards oncoming traffic and confirmed this on multiple occasions. Once when there was no oncoming traffic or anyone behind me, I allowed the car to see how far it would go before I pulled her back, and it was at least a tires width over the line before AI corrected itself back safely in our lane. I have also found that on at least one occasion the car swerved into oncoming traffic once the solid line became dashed as for passing. That was interesting. Since there are a lot of curves the car does jeter bug (around curves). For now I use auto cruise control, but not the auto steer along this route without being more than vigilant.

On major freeways (WA 101), I found our bluemax following a group of gamblers headed to the local casino. She must think I gamble more than on the Tesla stock she was all set to willingly follow traffic right down the off ramp. There was no traffic in the left two lanes going forward. Funny, but required paying attention. FYI that was last week.

Oh, and auto steer does not appear at this point to recognize speed limit signs with yellow background, like a speed reduction:-(

So I have used AP for a couple weeks now and have logged a few hours with it on. I think my issue is that the AP will swerve me to left and then redirect me to the middle of the lane. it'll often cross the lane markings when it over steers and swerves left.

Does anyone have this issue? I took it to DS and they found no problems. thanks.

Just came back from long road trip, we did the exact trip 2 month ago, ap2 was better last time. On this trip, we experience a slight left to right to left steer even on stright marked lanes. Disappointed with tesla.

What firmware? This thread goes back to April, so it's covered probably a different version of the firmware for each post!

I'm on 17.38 now, and will be doing more testing on a road trip next weekend, but posting any comments without having the version in the post or in your signature really doesn't tell us anything.

BTW, AP2.0 does NOT read signs, it uses the database until we are told different.

I did a long road trip from North Jersey to Corning/NY- almost 3-4 hours drive. The autopilot had some near misses but otherwise held up for 95% of the trip. the close misses were when there were off ramps or construction that made the lines hard to read.

 

[Electroman]

It is two lanes, one in either direction.

I would never use - AP 1 or 2 - driving in the left lane with opposing traffic only separated by a line.

To be expected.

I do this all the time, but with very little slack given to AP... plenty of disengagements because it's a little too close to the center line... it has improved quite a bit on 17.36 I'd say it's now very good at this if it's a solid line and not in a dotted passing permitted line.

I noticed yesterday on 17.38 that autosteer really seems to prefer white lines, so much so that it will dive across a two lane road if it loses the center double yellow to go for the white line on the other side, or at least try to stay in the middle of the two outside fog lines. Definitely have to keep your hands on the wheel with two lane roads.

It most certainly has a bias for white lines over yellow lines. My suspicion has been that the cameras are monochromatic and only see black and white therefore white lines pop with contrast while yellow lines are not as visible.

I just posted a video talking about the hazard that repaired cracks on the highway cause all sorts of problems for AP2, but not AP1. I will be publishing a thorough comparison shortly of AP1 vs AP2

I find this happens in the training or micro recalibration phase lately after updates... it seems to improve with time for me

Excited to see your comparisons! I’ve noticed more false identification of lines in last two firmware updates .... much better in some ways but these mistakes seem like they are shifting to new algorithm or camera integration or something ... new lines on redone roads are the worst offenders

Prior to the last update (pre-2017.36) I found AP was hugging right-side of lane. Once I got 2017.36, I found it was much better centered. However, yesterday it started hugging the right-side of the lane again. No recent updates, so there is either some background/silent updates happening or the vehicle is doing some self-calibrating and/or learning over time.

I would take it in for calibration. I had a misalignment issue on my MX despite the firmware updates and they fixed it for me. My issue was it kept jerking to left and crossing lane/hugging left lane. after taking it in, it's usually centered fine.

I have had a 2017 MX for a couple of weeks, and have been testing the AP for a reasonable amount of motorway and highway travel.
My feeling is that for LH driving (New Zealand) it really has a long way to go before being safe/reliable. Perhaps it is better in right hand drive environments?

Here's my findings:
- The car seems to hang slightly to the left of middle of the lane and wanders around. If you are in the right hand lane (the fast lane), you really want to sit slightly to the right. Otherwise you are really close to large trucks you are overtaking, and given both you (the tesla) and the truck wander quite a bit, there is very little room for error. I usually grab control just before passing anything large.
- As someone said previously, it is a *long* way from being safe on undivided highways (i.e. where there isn't a barrier). It wanders around, and even had one wheel completely over the middle line across the rumble strip and towards the oncoming traffic around a gentle corner before I grabbed it back. This was a well marked road.
- Anything at all confuses it... road repairs, old paint, bridges.
- It really seems to hate cones off to the side of the road, and drives at them. Similarly vertical strips (used beside the road sometimes) sends it all over the place.
- Bridges are very bad - here the guard rails tend to start wide of the road and become more narrow - kinda like this http://www.newzealandnz.co.nz/wp-content/uploads/2014/09/Small-Town-New-Zealand-South-27.jpg. but with a wider 2-way road. Even when the road and bridge are clearly marked, the car steers straight at the bridge entry wall. Its not even trying to stay on the road.

Sadly - bug reporting seems broken in my car so there's no way to report this stuff. I can use the audio "Bug Report" command, but it just says "Thanks". I can't even report the bug in the bug reporting software.

Just thought I'd note that the system did very well yesterday on a long curvy drive to the northern beaches on a two lane road - it started drifting a couple of times to the center, but for the first time, quickly corrected itself. I wonder if there is some sort of learning going on?

I find it perfectly safe to use though as long as you expect nothing. I'm always surprised at the people who expect the system to drive for them. It's just helping, you are still driving.

I'm not expecting full driving... but a more graceful way of handling itself would be nice
(i.e. fewer sudden surprises).I have to be ready for it to strongly swerve off at any moment,
which it does often even on well marked dual/large motorways. Wifey wont trust it at all
because you have to regularly and firmly grab back control.

I think I'm starting to learn the few scenarios where it can be trusted (reasonably empty divided multi-lane
motorways, no trucks, no repairs, no roadworks, no bridges or cones). It seems to do well
in rush-hour on motorways too - mainly because it is stop-start and moving at very low speeds,
so its sudden lunges are happening slowly.

Perhaps you are right - expect nothing so whatever it delivers will please.
Personally... I was hoping for more.

Have 4K on my X. Had a scratch on my windshield and a bad door sensor that prevented the car from accepting updates. Don't ask me why. Had window replaced and was told that one of the updates that I missed was for autopilot. My car did a pretty good job before the updates but was worse after. More jerky, and wood sometimes favor the right side. Took it back last week. They recalibrated the sensors all around and said they were "a little off". Ap is just now dialing in but it is improved and better than before the update. Hope this helps.

Does anybody think alignment could be an issue with this? I got my car recently. And it would drift to the right (pretty noticeable). I.E. While normal driving just let go of steering wheel and it would drive of the right side of the road with a little time. I was on a road trip home from picking the car up from Fremont so not much I could do about it. After getting home I had them fix the alignment. Maybe just me but it seemed to rock a little back and forth when I first turned on AP and would adjust more then I would like after that. Not sure it was consistent though. I have not had a long trip since fixing but seems better. Overall though I was pretty happy with it so maybe not that bad....

I have been on 2017.38.f8.... since the day I got the car (updating on the same day from .36).

 

[Tompilot]

The first thing they asked me when I complained that the car was worse after the repairs was "how is your alignment?".
So I would think that alignment could be a problem. Mine seems fine. Hope this helps
