Speed limit recognition.

Hi I have had 3 Kona's now . A petrol premium sport, a SE hybrid an now the 2022 ultimate EV.
On all of these I have been told that the car uses camera's to read the Speed limit signs.
I am sure that this can't be true as I have noticed on many occasions that when new signs have been put up or they have been altered my satnav carries on telling me the old speed limit.
Has anyone else experienced this?

The earlier deliveries of Kona EV in the UK in 2018 certainly had it - not so sure about later ones. This thread from 2019 might be informative - see the first couple of pages of posts...

My September 2018 Premium SE certainly has this feature and it works. Just goes dippy occasionally like for instance when a side road has a different speed limit sign, or I come off tha Aston Expressway onto the M6 (Spaghetti Junction) where there seem to be no speed limit signs.

I seem to recall that this should have been an at extra cost option but the early cars got this as a freebie. Even stories of cars having this removed. Fortunatly I still have this feature. It picks up temporary limits at road works.

My Ultimate definitely reads temporary road speed signs, that are displayed on the HUD.
I will check the built in satnav next time I use the car, I usually use Tomtom via Apple car play so can’t recall without checking.

Edit: I’m almost sure the satnav displays speeds supplied by the downloaded maps ie tomtom.

Well I absolutely loved the Petrol sport ! couldn't really fault it at all. Very smooth auto box, Loved the way you could shift to sport by just pulling the stick to the right. and loved all the gadgets.
The EV I only had it for about 7 months it was still a great drive but it's when it was running on the electric that I really enjoyed it. Unfortunately that was not for long enough.
With the silly price of 2nd hand cars I took the chance of selling it for what I had paid 7 months before and bit the bullet and paid out for the EV . Very expensive in my opinion but I do love it! :)
I was very very lucky to get a brand new one without any wait :)

Initially at least it was an option (ISLW) - Hyundai didn't originally intend to offer it, but some early demo cars had it enabled by mistake, and they did offer it as a paid upgrade. Not sure what the situation is on 2020 & later cars.
I believe later satnav versions show limits from mam data, so may be hard to tell if the camera-based warnings are enabled or not.

My 2020 Kona EV most definitely reads speed limit signs. Only today I noticed passing a side road that it picked up an errant 30mph sign that wasn't quite aligned correctly. In road work sections too it sometimes flips between the temporary 40/50 limit and the normal speed limit if there aren't enough repeaters for the restriction.

Indeed. 2021 Ultimate, and that generally reads signs correctly, but seems to be easily fooled. I have one section of road in a built up area that it thinks is 10mph and I have yet to figure out why. But, now that explains why I have seen ridiculous figures such as 80 being displayed!

Also I havehad a couple of occasions where it has read and displays a no-overtaking sign, but fails to read the Nebo of no-overtaking zone. So I’m pretty sceptical that it won’t always see the start of a section either.

Cameras that read speed limits are a mandatory part of the road pricing 'black box' system that has been installed to every new car for a few years now, together with the car's actual speed, GPS & driver info. One of these months the government will announce a switch on date, they're just waiting for most of the unfitted cars to be scrapped. If your car is under warranty, I'd get the dealer to check it out, otherwise when road pricing comes in my guess is you will get the bill. It will, if nothing else become a part of the MOT.

PS. The software is capable of 'billing' you for speeding, South Africa wanted that, if the government chooses to switch that bit on.

Care to quote a source?

My 2018 Kona doesn’t even have any external connectivity to facilitate such monitoring, and those with Bluelink are connected to a private service to which the government has no automatic right of access.

My original understanding (probably wrong, yet again!), was that there were local beacons carrying the speed data that could be received by suitably equipped cars, that would show the local speed limit. Now it seems from the current comments, that this data is merely identified by the car's camera. Its a pity that it is apparently not possible to get a definitive answer to the question of the data's origin from the manual. [ISLW?]

My Kona Ultimate 2022 manual says that the camera at the top of the screen reads speed limit signs, but the Nav system also provides speed limit data for display. I don't know how priority is chosen. It also mentions Manual Speed Limit Assist (If fitted).
This Hyundai video explains that it is possible to choose to have the car speed controlled automatically (in America) to match the speed limit signs (or SatNav data). There is a further option to add or subtract 3 or 5 MPH. The option does not seem to be available in my English Kona, though the road signs are read and displayed. I have many times felt that the car does settle on 30MPH by itself when I immediately select cruise as I pull away BUT I can't be certain this is happening! I may be kidding myself.
Does anyone know if this function is available in UK?
(I usually set cruise to 33 in 30 MPH areas because ALL speedos show 30 when the speed is actually 27.)

I think the priority is simply whatever changed last: if you cross what the map data says is a speed limit boundary the car's idea of the limit changes, and if you pass a speed limit sign it updates to match the sign.

I think Kia/Hyundai have missed a trick here that could increase safety... I am surprised that there isn't a button somewhere that sets the speed limiter to the speed determined by the speed limit signs. Then, all you would have to do to ensure you do not exceed the limit is hit the button every time the limit changes. I drive with the limiter set to the speed limit a lot of the time and it is a bit of a pain to have to reset it every time the limit changes. Little things make all the difference :)

I nearly always use cruise to keep me to the speed limit and Hyundai's smart cruise makes that even more convenient in most urban conditions near home. I too would love to be able to ask the setting to jump up or down to the next normal limit.(20, 30, 40, 50, 60, 70.) To make the alteration just using cruise requires several seconds attention. I would like to have the setting add 10% though, to arrive at real speeds. (The American version does seem to offer adjusting +/- 3 or 5 MPH for motorways)
