Pilot Assist, Adaptive Cruise Control etc.

[dgomes]

One feature that I was trying to install (on my 2017 XC90 T6 Inscription) was ASL (Ajustable Speed Limit) and CSA (Curve Speed Assist).

These, it seems, came out in 2020 (maybe 2019) with Pilot Assist 3. My car has Pilot Assist 2...

We managed to change the config and the ASL and CSA buttons showed up. But upon activation I could see no change in car behavior...

My take, at this point, is that is it likely to be dependent on Pilot Assist 3, which my car does not seem to have. (or means to be upgraded, I guess...)

Another possibility is that ASL and CSA need additional specific GPS information (for CSA) and maybe some Road Side Information / conversion? for the ASL...

Does anyone have further hypothesis and/or ideas to try?

I had done some testing with my car as you know. CSA was enabled but didn't seem to work. The ASL did work.

I did find a further setting for Nav map data to include "speed info" or something like that, did we change that on your car? After I changed that on my 2019 S60, I got a "Nav map update" notification the next day...coincidence? Who knows! Now I can't remember what happened next ha, I think I lost interest, as I was just curious about it but the CSA/CSW and ASL/SL stuff didn't have a lot of use to me. I may have turned it off last config update.

[dgomes]

I think the only parameters we changed were ASL CSA and max speed limit.

I will look to see if I find other speed related config lines.

[Power6]

Check out Road Sign Information, change the "without Speed Limit Adaption (SLA)" version to "with Speed Limit Adaption (SLA)" setting, for your appropriate country. Don't know if that does cause the loading and/or use of the SLA data, but I believe that is where the information to drive CSA is pulled from.

What about trying to enable PA3? It looks like this is set via the 'Auto Pilot Function' parameter.
I'd guess that the PA3 and CSA/ASL software was developed after your car was manufactured, so it's a question of whether the new code has made it into your car via some of the routine software updates. There is of course the question on whether PA3 had any additional hardware dependencies.

[dgomes]

I just looked into that (Pilot Assit 2/3).

The only parameter I found in reference to Assist 2 or 3 on the Variant Attributes was:
On a 2017 XC90: KI03 - TRAFFIC JAM ASSIST - With Traffic Jam Assist 2;
On a 2022 XC90: KI04 - TRAFFIC JAM ASSIST - With Traffic Jam Assist 3;

The question is whether the 2017 car was at any point updated to a new code.

Any guess in which ECU that code would reside?

Besides just trying it out, I could look up the Hardware and Software page for each car and see if the respective ECU hardware and software are of different or equal versions, that could give some clue.

[Power6]

Lot of unknowns with PA3 yeah. A lot of what we don't know is how the conifg readouts translate to the config string of the car, which is what goes into the config files. There is some interpretation there. I have seen there are "config logic" files that can occasionally get updated from Volvo on the CEM. that appears it might be the code for how items are translated. That's a mystery for now.

PA3 could be a real software update/load though, maybe not even a config item, but actually updating existing code of the existing feature. Could be a number of modules, ASDM, VDDM, BCM, PSCM would all be involved in PA. The PA3 upgrade is available as an accessory I think...anyone want to try that, and capture those software files ;-)... I guess if VIDA even lets you buy that. I know you can buy the PA install accessory as an individual in VIDA in the US, it's not restricted like the Polestar Tune.

Wondering if the following levels are supported on MY16 XC90

023. CRUISE CONTROL Adaptive cruise control stop & go, level3

145. TRAFFIC JAM ASSIST With Traffic Jam Assist, Level 4

314. ADAPTIVE CRUISE CONTROL VERSION ACC version (1,2,3,4 ?)

318. AUTO PILOT FUNCTION (HAD ) Auto Pilot level (1,2,3 ?)

Don't think so - sorry forgot to reply to PM.

Remember what you have the file for is the Polestar 1. I.e the latest and greatest.

Radars, cameras etc have been updated over the past 7 years. What is in your file is known working - unless somebody pops up with a Variant Attributes for a fully loaded XC90 from 2016 that has had dealer updates recently then we aren't going to know. You can play with the settings - but do you really want to risk it with a self drive function and end up off the road? I didn't... Hence your settings mirror what I know to work

[Power6]

You *could* play with it, that's how you find stuff. But probably be careful. What I know so far is "Auto Pilot" has nothing to do with Pilot Assist. I remember now that SPA XC90s were used for Uber autonomous vehicle testing in Phoenix, AZ. I think that config might refer to that or other autonomous vehicle testing programs.

The other levels don't know too much about. Just what others had shown me that works. Maybe one of the levels has to do with auto lane change with PA when you activate the turn signal (car must have side sensors like Park Pilot Assist requires, to work). You might try the settings and not drive the car at first, just see if you get config errors, or DTCs for missing hardware needed.

I'd be up for if one of the ACC settings would make it not time out in stop and go traffic! PA2 is no big deal to me (I'm real good at steering) but the stop and go handling, that feature is awesomely relaxing.
