Traffic sign recognition code activation

[Ted1999]

Hi all. I have searched on this topic but can't find a precious thread. I live in Australia and the traffic sign recognition is not activated. As it is available in other areas I assume there must be a way to access the code to switch it on.
Is anyone aware of an aftermarket product to do this?
Thanks!

If possible you will need PIWIS to access and activate. Your dealership is the obvious candidate but they may not do it.

It's not always accurate anyway - going through a 20mph village the other day I had a nice red 100 sign on my dash would have been hard pressed to reach anywhere near 100

I thought traffic sign recognition was part of the Lane Keep Assist option (LKA). Does your car have that option?

Yes it does, but the traffic signal recognition is turned off in Aus. I had it in my AMG and it worked well

Is air suspension now enabled as that was disabled by region also?

It's horrendously bad. You're better off rolling a pair of dice.

It was even worse in 2021, at least after all the updates it's sometimes correct. But 70% correct is still utterly useless.

Even in Germany.

That is so odd. My AMG was accurate I would say at least 95% of the time. It was very rare for it to get it wrong and when you think of how easy recognising a speed sign is versus some of the other things the vision system has to do safety wise, there isn't really an excuse!

Me too.

The main failing is down to missing signage not the tech - particularly after roadworks where a speed limit has been imposed and the sign to reestablish the normal speed limit is missing.

The other issue is inaccurate mapping data.

For these reasons I don't use the speed limiter with sign recognition as it can lead to unexpected braking.

I would expect innodrive to be similarly impacted.

Can't blame the car for everything.

I always run a GPS app on my phone ("FlitsMeister", with radar and traffic conditions warnings) which is more like 99% accurate, pretty much all over Western Europe. Certainly on highways, but even off.

Google Maps also has a maximum speed indicator that has a similar accuracy, although I don't use it that often.

Porsche really is so often so wrong, even on highways with nothing special going on. Initially I could make some excuses for it as the maximum speeds on Dutch highways had been changed a couple years ago and they do have confusing time of day restrictions below them. Often 130 at night and 100 during day times. But in other places it's 120 at night or 80 in the day time. (That's ignoring the dynamic speed limit on LED displays.)

But then again they have similar (as well as even more confusing combinations and conditions) in Germany with otherwise the same signs. Having since visited most other countries around here, I can say Porsche is not much better there either.

I too have seen fairly simple Mercedes and Kia models, probably starting around 15 years ago, display speed limits pretty accurately. It always made me wonder whether they did vision or GPS mapping. Both of which were pretty remarkable for the time: with the limited vision hardware/software capabilities and no over the air updates of maps, let alone a 24/7 internet connection.
