Just having a lunchtime browse through the used car adds - well, it idles away a few minutes. I've come across Renaults fitted with...

Critical Sliding Velocity understeer control

A quick Google throws up lots of Renaults fitted with it but nothing to suggest what it does or how it does it. Anyone care to make a suggestion - either factual or something humorous that's made up.!?

Well, there's a video:

The name 'Critical Sliding Velocity' is a load of arse to cover for the fact that its French name is Contrôle or Correction de Sous-Virage (understeer).

Hmmm so it's ESC but from their website, 'enhanced by an additional understeer control function which corrects understeer in emergency situations.'

Does 'classic' ESC only correct oversteer then?

I wonder if the Renault system identifies the 'I've steered too much, stalling the tyres, causing epic understeer and I'm about to crash' moment and gives a little more impetus to turning the car around what it thinks it can achieve rather than what it thinks the driver is telling it.

ESC algorithms are a bit of an art form at best.

Wait 'til steer-by-wire becomes the norm :lol:

'Steer by wire' is the future, eh?
