It's nothing to do with how much you raise the pedal though. It's about the amount of deceleration in metres per second.

So if you're doing 100kph, the tiniest release of pressure will trigger it.

If you're barely moving, you'll basically need to lift your foot right off the pedal.

You just need to trust it!

I might buy a mirror with a suction cup so I can see my brake light during a normal drive. And then I will know how much I need to raise the pedal before brake light shows I don't want to be rear ended cause my brake light didn't engage.

just drive at night where there is no streetlights, its very easy to see and learn when the brakelights come on.
they problably light up more if you DONT use OPD.

And steering and throttlemapping and OPD has changed every update since we got the car 6 months ago, biggest change was 2.7.
Smallest change was 2.8-2.9 now. Very tired of this, but sure, they have changed things for the better, but that has had a price that have made the car overall less involving and fun.
The OPD after 2.9 is ok, would love it like 2.5 again but as long as they dont do it worse then this again I dont have a huge problem.
the steering is the biggest problem right now and the throttlemapping lost the fun with 2.7, got it back with 2.8 and lost again with 2.9.
Now the mapping is some strange mix between 2.7 and 2.8 and doesnt have the good thing from any of them!
it was boring on 2.7 but very linear and easy to modulate when gunning it, you knew the last bit of pedaltravel would always get the hardest push, like a NA car!
But the fun with 2.5 was that it built up speed/power on half throttle like a turbocar and you got this little pocketrocket behaviour that felt fantastic on small pulls.
that came back with 2.8, but 2.9 moved that longer back on the pedal again and messed up everything.
And the steering lost confidence, and that is a big nono, but since 2.8 its better then ever (stable) in high speeds, if you have hard steering and lka on!

and for everybody that has not yet updated there car to 2.10, start noticing how your car feels in different roads and settings and how much throttle is needed at what speed and how the opd bites and WHEN it bites, because the biggest difference in opd is the ”deadzone” between throttle and braking, it used to be razorthin! Its not now!
That is both good and bad, but its sure is less fun.
But start noticing so that you can notice what changed! Because 2.10 WILL change these again, because that is as usual what volvo firmware says, and its said that for every firmware that polestar says it didnt!

I'm going to go out on a limb here and say that either your car is broken or you have a very vivid imagination.

I went to the service and they presented to me the design documents of the architecture for the OPD subsystem and is currently capped in v2.9 to 0.25Gs, no matter how fast or slow you go the car will never apply a major brake force that surpasses that amount automatically, you have to press the brake pedal now for that. You can open the Performance App and test to confirm this.

In v2.4 I remember it felt like 0.4Gs, which changed in v2.7 to about 0.3~0.35 Gs. I do not have my car at that version now and I would never imagined this was going to be changed creating such an undesirable driving behavior so I was not measuring that at those moments. But anyone on the forums with the car still using any of those version could sent us a video to confirm or not this.

it felt like 0.4Gs

How do you translate a feeling to deacceleration force?

are you talking to me now?
do I really need this everytime I am trying to talk about changes to the cars?!
how many red cars have you seen today?!
probably none! Since your brain isnt looking for them!
But now that I asked you there will be either tonnes of red cars around you or you will notice the lack of red cars!
Me, I am looking for red cars 24/7, and doing that I will notice any increase or decrease in my observations, down to x amount.
This is why I am telling you to notice how you car feels and behaves, otherwise you wont notice any change, if its not huge.
but still most people completely misses enormous changes to this car!
like the lka steering problems that now are gone! But gone is also the good steering without lka.

If you dont notice these things then fine! I dont care! But telling me I am imagining because you or your car dont feel anything, THAT I do care about!
come back when you care about how a car drives, feels, behaves!
And we should add that this car needs a very curvy 50-70km/h road to come alive, start there if you have not and BE AWARE of the cars behaviour and your inputs!
and then update the car and see if everything is EXACTLY the same.
Good luck!
I am leaving this thread so dont bother replying!

And much of that "remembering it felt like..." could well be just your own experience due to the experience being novel. Things always seem more intense when they're new. I'll use as an example the shower in my master bathroom. After a remodel, I had installed a waterfall in addition to the regular head. At first my wife hated it because she said she felt like there was just too much water and she was drowning (her words) when showering. Now some 8 years later she complains when she has to travel and stay in a hotel because it just "doesn't feel like it gets me as clean as our shower at home". The novel experience was more intense, but as she became accustomed to it she has grown to really like it.

I've had my car since 2.0 days... I seem to recall my car arrived with 1.8 actually and then got the 2.0 update shortly after I got it. Anyway, I have only noticed one significant change in OPD deceleration which was when they made the engagement of regen gentler. However, I don't use my brake pedal any more today than I did when I got the car and in fact I noticed in 2.7 that the OPD regen became slightly more "intense". I drive the same routes roughly today than I used to and I've had no problems with OPD at all. It's not as "novel" and you're correct it doesn't feel as "intense" as it used to but I have chalked that up to my "experience fatigue" with the deceleration rather than an actual reduction in deceleration on lifting off the pedal.

 

[lermy3d]

How do you translate a feeling to deacceleration force?

I tested empirically by braking with the Performance App opened until the G force applied by my braking it felt like I was on 2.4 again, same for 2.7, which was in-between of what we had in v2.4 and v2.9.

 

[lermy3d]

Things always seem more intense when they're new.

I could probably had a agreed with you if I was indeed new but after having the car for months, almost a year now, and overnight after doing an update I had to slam the brakes at my first drive the other day which I have never had to do before in the past 8 months since I got the car... it just does not explain why the lack of braking force.

Then there's a nonzero chance you have some sort of problem with the software. Maybe a register got tripped or something. I presume you've tried changing the OPD strength levels back and forth to see if there's a difference?

I think the general consensus here seems to be that the problem is either you or your car rather than some inherent problem with either the car or update. It might be worth a convo with Polestar and see what they say because your experience doesn't seem to match the general experience. In fact after a quick jaunt in my car (needed to go get dog food) I can say that in my opinion the regen braking is better than it was at some points during my ownership and certainly no worse than it was when I got my car. Now again as I noted some of that could be tempered with the fact that I might not be perceiving it totally correctly, but I can say I didn't touch my brake pedal once during today's drive... so there's that datapoint

 

[lermy3d]

presume you've tried changing the OPD strength levels back and forth to see if there's a difference?

Yes!! I tried that at no avail, I turn it off and on, changed profile, which indeed it feels even softer en the Low profile, if I recall correctly right now the Low profile is capped at 0.1 Gs, perhaps it has more decimals but they do not display that level of accuracy in the Performance App.

I think the general consensus here seems to be that the problem is either you or your car rather than some inherent problem with either the car or update.

I think you have missed quite a few comments, LOL, I don't blame you the thread is at 152 comments of everyone given their impressions on OPD.
But I can point you to this other example: Where others have experience "the panic brake"
So this is not specific to my car.

It might be worth a convo with Polestar and see what they say because your experience doesn't seem to match the general experience.

I did that already: I took the car to an appointment to the service.
They said there is nothing they can do.

but I can say I didn't touch my brake pedal once during today's drive... so there's that datapoint

There is also the fact that we have compared behaviours from my LRDM which brakes in a slower time compared to a single motor version!!! which is absolutely bunkers: Side by side comparison braking tests.

But yeah, that is basically a summary of this thread. So if you do not feel it have changed you are basically starting to brake earlier than before and adjusted for that unconsciously, is either that, or your car did indeed had no change, in which case it might be a bug affecting only some of us. Are you already on version 2.9? That version is when OPD became way too soft, on my car at least.

 

[aviblack56]

The 'One Pedal Drive' feature is getting useless after 2.9 update, moreover it has gotten way too soft on this update specifically, even though I personally wrote Polestar about the first change they made on this lane when they change it from the good, reliable and stiff on 2.4 to softer 2.7, just like there was no 'Low Profile'. The 2.7 version had a softer regenerative brake even in the 'Standard Profile', which is the strongest value possible to setup for it that is user faced.

In the first 24hs after using software update v2.9 I had to slam the brakes twice on that day or else I would have crashed into the car in front because of this chabge.

Which begs the questions:

1. What is the point of having a 'One Pedal Drive' feature if you have to use 2 pedals? None.
2. Are we safer with this change? No, we need more distance and space in front of us to fully brake.
3. What happened with driver's muscle memory after getting an update that changes the way we have adapted to learn? Muscle memory is useless now.

Let's review how this setting would it be in a world where drivers could actually customize their driving preferences:

Bottom left corner, in case it went unnoticed.

Adding a poll to get attention on what are drivers preferences on this regard.
Also, do you guys use the Low profile?

In my case I actually would prefer a value in-between 2.4 and 2.7 but the UI does not provide a way to let me set my preferred customized driving style for that matter.
Unrelated but since the feature is on the same screen and I have also stated the question to the Support Team: What is the purpose of a Creep function without 'auto braking'? No response yet.

OPD is my favorite “feature” on the car. Not only does it add to safety, in my opinion, it makes the car so much more fun to drive. My greatest dread in moving away from my 325i with a stick was losing connection with the “driving experience”; this is as close as it gets to bringing that aspect back to driving without having control over gearing (which is obviously not part of the EV driving experience). I drove several IVs in the process of buying my Polestar, and found that its OPD is most to my liking.

That said, I think your idea is brilliant, and I certainly hope that the company will update the software to make it so.

 

[ThunderEyes]

I did that already: I took the car to an appointment to the service.
They said there is nothing they can do.

Maybe you should try test driving a Polestar 2 at your nearest Polestar space. See if you get the same experience in that car as with your current car. That can help you determine if there's something wrong with OPD in your car.

After reading this thread a couple days ago, I started actively monitoring how often I needed to use the brake pedal. (Driving LRDM + standard/full OPD + no creep + sport mode disabled)

I did 6 drives which included a mix of freeway and city (more than 50% of the time city) driving. Altogether, in that time, about 2 hours of driving. Didn't do anything special/unusual, just drove normally.

Over the course of all that time, I used the brake pedal exactly once. It was when I was driving aggressively to a stop sign and had to slow down quickly. Other than that, didn't need the brakes once, on freeway, stop signs, speed bumps, or lights. I'm not sure why your experience is different, but it certainly doesn't match my experience driving my AWD P2.

Lastly, I'll add that I'm around the 15-20th percentile of aggressive drivers and that it's extremely rare for me to even need to fully take my foot off the acceleration pedal while driving, so the max G force available from OPD isn't even utilized.

 

[ThunderEyes]

Just to make sure we're on the same page, are these the settings you're using?

 

[lermy3d]

and that it's extremely rare for me to even need to fully take my foot off the acceleration pedal while driving, so the max G force available from OPD isn't even utilized.

One test you could do to verify that the max force available is not utilize is to select any speed you like, can be 40km/h, can be 60km/h, open the Performance App, then lift the foot altogether while doing nothing else and let the car go into a full stop on its own. If you are on the Standard profile you will never see it go beyond 0.2 Gs on the Performance App, if you are on the Low profile you will never see it go beyond 0.1 Gs.

If you apply the breaks you will see it go beyond that automatic maximum limit, and it can go from 0.3 to 0.5 depending on how hard you are going and how hard you slam the brake.
But in the automatic OPD system your car will indeed try to utilize the maximum G force configured if you remove the foot at once. Which is what I stated above, 0.2Gs for Standard, and 0.1Gs for Low, 0 of course when OPD is off. This is how is working now on v2.9.

It's very rare to fully lift my foot off the accelerator pedal, so I'm not sure how useful this is to examine. Is this something you did a lot before the changes you noticed in 2.9?

There are no other settings for OPD anywhere else on the UI of the car. So yes, that is the only page where you can do that.
