Speed limit recognition is dodgy

[SteveG511711]

It should work, but many times it doesn't. There are a lot of stories of it picking up the wrong speed limit from Wheelie bins with numbers on (or any sign with white lettering), side road speed limits in error. I suppose it's trying to do it's job, but on a straight major road I travel it mises the national speed limit sign and stats in the 40mph preceding it, then 100 yards further on it changes it to 60mph (which is what it should be). So, what's going on, is it cross referencing the speed limit through GPS like sat navs do? Possibly, because I had another instance where one part of a major road I use changed the limit from 50moh to 40mph bug every time I reach that point it changes it to 50mph. Does anyone have an answer? The local MG dealer doesn't ?

Hi 'PTW', thought that it was just me? Sometimes I am driving along, minding my own business and trying my best to stick to the speed-limit and then, indicator suddenly shows 100. Took me awhile to sort out what 100 meant. MG dealer, "Oh it has gone into Kilometres instead of Miles". Oh, that's OK then? Mostly it reverts back to miles after a short drive. The MG3+Hybrid Trophy is certainly the strangest and quirkiest car that I have ever driven! I am learning to live with this strange beast!

The system is comical in the way it hardly ever gets it right, I may even have to look where I'm going soon.

What really irritates is when I'm in a genuine speed limit that it has got right I may 5-10 under the limit and it covers it up and tells me to "SLOW DOWN" why does it do that, it is the crappiest software I have ever had to work with, and I sold puters for living in the early 90s

Mine doesn't tell me to slow down. It just starts to beep if I am 1 km/h over the allowed speed limit.

I think I saw the possibility to set up a general speed limit warning in the menu, which is deactivated on mine. It's somewhere in the menu on the dashboard screen... Might this be a possibility?

I think it's on the steering wheel right hand side.

hello, alex144, but do you have to reactivate it each time you start the vehicle? This is what I have to do to stop hearing the overspeed beeps

 

[Alex144]

I'm not sure if we're still talking about the same thing.
The general speed warning (sign recognition), which only beeps, cannot be switched off permanently as far as I know.

Then there is the manual speed warning (one speed limit can be set), which in my case issues a text warning "slow down", I only tried it on once for test purposes. However, it also remains off permanently when deactivated. See picture.

great, thank you for this additional information

Having travelled quite a few kilometres observing this recognition of limit signs, I can confirm that I have not seen any aberrations in signage on French roads.

If you really want to confuse it, try crossing over a border from a 50kph sign to an area where the sign reads 30mph. It takes a few minutes for the GPS to catch up and realise what's happened.

Wow, 70 linux versions, things have changed since I last looked.
Do you have a favorite?

The easiest way:

UBUNTU

Used exclusively since 2008, I no longer have Windows with its bugs and viruses.

I don't mind the speed warning per see, it's just a reminder.

I don't believe we have a Linux user on here, tried it and couldn't get rid of it fast enough I'd rather be spied on.

In some systems it is is combination of sat nav database info and the camera recognition. So if the camera has not passed a speed limit sign for a certain amount of time it will revert to the "known" speed limit from the GPS data.

This was certainly the case (in my Mini) when roads near me went from national limit (60mph) to 40mph, 30mph and 20mph zones. The car would revert to its GPS data and always show the wrong speed limit.

Does this Nanny software have a name?

You're obviously wrong, there's Italy and me at least. I won't go near windows either, it drives me crazy

How come? We don't bleed anybody dry.

Frightened of Windows

No not frightened, just frustrated.
