Annoying slowing in Adaptive Cruise

[madmanacrossthewater]

in our new EV, I have noticed that when in cruise on a country lane, and enter a slight bend, the car slows down, and down and down going round the bend.
I always use Cruise control, but find this really annoying, does anyone know if it can be "muted" whilst in cruise?

Thanks all

Unfortunately not. You would have to temporarily take it out of ACC and then resume.

Or just apply some accelerator pedal during the bend. Of course, that negates some of the reason for using Adaptive Cruise Control in the first place, but I find it useful.

Thanks for your comment, but if I do that, the KERS would slow it down even more

I guess that is what I will have to do,. Annoyingly, I know its a safety thing, but it just gets slower the longer the corner...

As coulomb has said, I just help it through the bend with a little pressure on the accelerator pedal.

All cruise control systems that I have used (ICE included) have a feature that senses the cornering forces and slows the car if these become too great. Some are more sensitive than others and this can spoil the drive on say a fast relatively slight bend. Some systems won’t slow until there is quite a lot of cornering force.

Hyundai and VWs I've had didn't do this (both with radar cruise).

I think this is a Chinese car thing.

Totally agree....our Peugeot 2008 didn't slow on the bends.
I'm not sure how long the corner would be until it totally ground to a halt!

The Ioniq 28kWh didn't do it, but the Kona did and it wasn't as severe as the ZS.

Agree it's a pain in the neck. Even worse on motorways when it does it when overtaking with cars behind. They must think your are an idiot.

Regarding the KERS comment, try dropping it down from 3 and it won't have the same impact if you knock off the acc. I tend to do that on back roads for the same reason.

I get annoyed by the same "feature". I've found that it slows down less if you have it in Sport mode though.

Could the slowing on corners effect be controlled by changing the radar control system? The slowing might be due to the radar noticing the corner? Or it might have an input from the steering system?

I believe it engages based on how far you're turning the wheel. I've not done a proper test, but my experience it allows more turning before slowing down when in Sport mode than in Normal or Eco.

I have noticed this effect, it only seems to happen if the road has a concrete wall - divider and only on a few roads. Next time I might try reducing the radar distancing setting to "1" (closer) and see if it occurs.

Good idea

It's intentional. From the manual (page 207):

"When driving on a bend, the adaptive cruise control may actively reduce the vehicle speed to maintain vehicle stability and safety."
