EV general discussion

It's weird how different limiters/ACC work for different people. I use ACC all the time in my ID3, probably for nearly 50% of my 45mile commute and love it.

I've had to switch to limiter in the C3 hire car as it's just got dumb cruise and it feels like going back to the olden times.

I wouldn’t have a car without adaptive cruise now - spent hours of my life looking through autotrader for an EQC which had the optional extra pack with it was it wasn’t standard on any trim level. Only way you could tell (any adverts never mentioned it) was the slightly different set of buttons on the steering wheel…

I use it everywhere - just set to the road speed limit and let it do its thing. Have to remember the OH’s EQC doesn’t have it and is liable to plough into the traffic ahead when using bog standard cruise :D

Never used a limiter in my life - not sure I like the idea of the car just saying no if I’m trying to accelerate…

Lots of cars with one pedal driving will do that anyway.

There's a huge hill in the town near me and it's a 20mph limit. With my regen set to auto I can go down it at 20mph and if you take your foot off the accelerator it'll stay at 20mph anyway.

Depends how steep the hill is


A good implementation of a speed limiter takes variance out of the situation.


Set the speed. Go. Change when needed.
 
Time is money. I drive as fast as I can to get to destination on 1% battery at arrival. Bigger battery for the win. Couldn’t care about 2.7/m vs 3.5/m when it’s so cheap anyway

The ID 7 has a manual one.


You set the speed and you can’t go above it unless you floor the accelerator


It’ll brake going downhill too, which is handy for a few hills with speed cameras on them

That’s exactly what the adaptive cruise does

I'm another speed limiter fan, its excellent on a crowded road/motorway/town as a safety net when adaptive cruise just isn't practical.
 
I have seen ACC used in some very dangerous situations. A guy actually stated his EV shot off in an SUA (sudden unintended acceleration) at a red light and almost T-boned another car had he not been alert.

On further inspection it seems he had enabled ACC in an urban environment to drive for him in rush hour traffic. At a red light the car in front got a left filter light but the driver claiming SUA was going straight ahead.

So ACC seeing the road ahead was now clear, and of course not knowing what a traffic light is, accelerated off just as it is programmed to do. Somehow this driver still insists it was an SUA and not incompetent and downright dangerous use of ACC*.

Note standard ACC, not some form of autonomous driving that sees traffic lights.

Indeed - they’re all driver aids, and it is absolutely the driver’s fault for not knowing how to use them properly.

Sounds like they were using one pedal driving and just mashing it on or off, and let's face it taxi drivers aren't generally known for their great driving anyway :cry:

It’s literally not


Adaptive cruise is setting a speed target, a limiter is a speed limit



With the limiter, you retain full control over driving, except you just can’t go over a set speed. It means you’re fully engaged in the drive.


Adaptive cruise takes control away from you and tries to manage the speed for you, and in my experience does a poor job.


You need to turn it off for roundabouts, tight corners, urban environments and other situations where you don’t want the car targeting the speed you set.



They’re completely different systems trying to achieve different things.

Agreed, I always use the (manual) speed limiter, basically means I can just drive normally but can pay more attention to what's going due to not having to keep half an eye on the speedo to make sure I'm not creeping over the limit.

Not a massive fan of ACC on the other hand. If I set it to e.g. 70mph it's because I want to do 70mph, not "whatever speed the car in front is doing up to 70mph". It's alright in slower moving traffic (although at that point I tend to switch it off as I'd rather be fully in control due to the increased number of hazards) but on a relatively clear motorway when you're approaching a slower car you either have to move out extra early before the ACC kicks in, wait until your speed starts to drop, or figure out that precise moment between too early and too late. With normal CC you just move out when you're at the correct distance without any of that faff.

They both have their merits, and ideally a car would have both, but given the choice, I'd take standard CC over ACC any day.

This wouldn't happen in my car, as if it's fully stopped for more than a few moments then you need to either tap the pedal or cruise button to move again.
