new speed limiter law now in effect

i've not heard any info on how the various manufacturers have implemented this though; there seems to be a dearth of information on what's quite a significant law change.

had it on a suzuki vitara in Poland a few years ago. basically flashed the speed at you when you passed a sign. the sat nav i had was better.

I would expect it is a GPS linked system to a speed limit area database, so the vehicle knows where it is and what the speed limit will be. It's not clear whether there is just a warning or the speed will automatically be limited.

The article mentions that the system can automatically reduce the vehicle's speed if warnings are ignored (3rd paragraph).

this example came up in a previous thread; how will a GPS system safely and consistently distinguish between two roads very closely spaced, where the speed limit sign from one road is visible from the other? the most obvious example i can think of is an off-ramp from a motorway where the posted limit can be half what it is for the motorway lane less than 10m away.

likely it won't be that sensitive.

Speed on the Naas Road and M50 is 100kph, but the slip joining them is 50 or 60kph. You're only on the slip for 20 seconds, so I doubt a system will force you from 100 to 50, then prevent you from accelerating back to 100 to merge onto the M50.

I imagine speed limiters won't limit you to the posted speed limit, but will instead limit you to excessive speeds. 140kph on a 120, 50kph on a 30, stuff like that. It's still up to the driver to maintain speed to the posted speed limit.

Put bigger wheels on the car 😉

That article from Cork Beo refers to "here in the UK". 🤨

Daily Mirror group website, just recycles content from other ones. DublinLive is the same group too, and a Galway one.

As I understand it the system will alert you in multiple ways that you are exceeding the posted limit , but you will be able to "ignore" it.

Some will introduce an artificial pause in the throttle that you'll have to push past.

For example , today I drive a PHEV and if running on battery only, if I want to "force" the petrol engine to kick in I have to push down a bit harder on the pedal so that the computer recognises the request... A bit like an computer enforced turbo lag pause..

I would imagine that this system will feel a bit similar..

Like DRM for cars. Between this and paying to turn on your heated seats in BMW the future is not looking too rosy ...

If these kind of systems are going to become mandatory then they can only work properly if the information they're being fed with is accurate. This is a problem though at the moment ...

1) GPS based speed limit data in car satnav systems is often incomplete, inconsistent and in some cases plain wrong.

2) Camera based speed limit detection systems are prone to error in many ways, twisted signs on side roads being read by mistake, non-standard signs like the 80/60km/h signs on the N11, mistakenly reading speed limit signs on the back of commercial vehicles and missing speed limit signs after roadworks to name but a few.

Still curious that there's such little info about it, the car companies certainly aren't boasting about it, perhaps they're worried it might dent sales a little?

They are now mandatory, some use GPS sat nav based database, others use cameras on road signs, others a combination of the two. You can over-ride the speed by pressing the pedal harder. The systems are far from perfect. Once all cars on the road have them the penalties for speeding will increase, that's the aim.

You'll be able to disable it through software no doubt. You can do things like disable the seatbelt ping, or the start/stop feature if you want to as it is, so this will just be another tweak.

Where it'll get interesting is if insurance policies are adjusted to account for this tech or if it'll fall under modding the car.

Intelligent Speed Assist systems have been installed on cars for a while the only change is to make them mandatory and to be on by default. I've used the ISA on my car, it's OK, but I find it impossible on the M50, it finds it hard to distinguish between the main line of the motorway and parallel slip roads.

It's not to stop people doing 140 on a motorway. It's to stop people doing 121 on a motorway.

I had this in a hire car years ago that was set manually. When you hit the limit you set it would restrict the power for a bit. I'd set it to 30mph by mistake and when I tried accelerate to join an A road it really struggled to get up to speed. Hopefully you will be able to turn it off at start up.

No doubt we probably won’t see any discounts to account for this new technology anyway🙄

I had a TomTom SatNav previously ( when not every car had them as standard ) and when you hit a speed limit, it warned you in no uncertain terms, and you would back off the accelerator pretty quick, just to shut it up!!! But in all fairness, it did wah it was supposed to do, and I still use it just for that purpose even though the inbuilt satnav is far better, so I put it in the glove box.

i suspect you're confusing a basic speed warning (which my 2012 car has) with a supposedly intelligent system which can actively read the currrent speed limits?

You keep an old Tomtom sat nav unit in your glove box to warn you when you go over the limit???

You have to charge it regularly and keep it updated. What's the point?

Larbre34

The ISA can be turned off at the beginning of each journey and overridden easily by gunning the loud pedal even while its engaged. Just like lane keeping can be now.

No doubt there'll be patches available commercially to trick it out entirely even when it becomes an active system in 2024.

Otherwise I highly recommend my trick for avoiding the annoyance and expense of modern in-car tech, buy a 6-cylinder BMW from pre-1992 and keep it forever. Not a screen to be seen, nor an intrusive feature to be screamed at. 170hp, power steering, ABS, sounds mega and only fifty quid to tax as well!

I drove about 2000 miles around California last month - the sat nav / cruise control had a massive problem keeping up with the actual limits on the roads. At times using the assisted cruise the car would suddenly just slow down as the sat nav decided the limit was reduced while the signs are saying a different speed - and then the sat nav on apple maps would have another limit. I was painful to use and some what dangerous to suddenly decelerate on a free way when doing 70mph with cars all around you

I got it in either 2018 or 2019, with life long updates included, and it charges off the 12v socket. I only use it now for its speed limit warning capabilities, but I still keep it updated anyway, simply because I can. Normally, I use the cars inbuilt sat nav, with its bigger screen, but the mobile phone Google one, is great too I find. There are towns and villages near me where you would think that you had passed the exit speed limit sign, only to find out that you had not, or even if you were just cruising along on the highway, and find that imperceptibly the speed has increased to above the limit.

magicbastarder

and find that imperceptibly the speed has increased to above the limit.

there's an easy way to perceive that!

It was a manually set limit, which I'd set to 30mph, and the car died when I tried to accelerate onto an A road luckily there wasn't any traffic as it could have been nasty if I was trying to merge onto a busy fast flowing road.

But with the "intelligent system" it's going to be worse unless it can be turned off. I've often being driving on a motorway and Google maps will pick up a merge lane limit and warm me i'm speeding, image trying merge safely onto a 120km/h road and the car thinks it's still on the 60km/h section and slows your car when you want speed?

Article here from the EU Road Safety groups explaining how it's going to work

And a more specific one here

The key bit of info for this conversation appears to be this

The ISA system is required to work with the driver and not to restrict his/her possibility to act in any moment during driving. The driver is always in control and can easily override the ISA system.

The ISA regulation provides four options for systems feedback to the driver, from which car manufacturers will be free to choose from:

Cascaded acoustic warning

Cascaded vibrating warning

Haptic feedback through the acceleration pedal

Speed control function

The first two feedback options do not directly intervene but only provide warnings (first optic and if no response from the driver, a delayed acoustic/vibrating warning), which have to be as short as possible in duration to avoid potential annoyance of the driver.

The other possible feedback relies on the pedal restoring force - it will push the driver’s foot gently back to make the driver aware and help to slow down. The driver can ignore this feedback and override the system by pushing slightly harder on the acceleration pedal. Even in the case of speed control function, where the car speed will be automatically gently reduced, the system can be smoothly overridden by the driver by pressing the accelerator pedal a little bit deeper.
