I was wondering how does the KERS3 mode perform when slowing down on icey or slippery roads. Is it safer than using brakes?
I had the same thought the other day.I was wondering how does the KERS3 mode perform when slowing down on icey or slippery roads. Is it safer than using brakes?
Had this a few times with the Prius, it gives the impression that the car is suddenly accelerating, not noticed it yet with the ZS though.This is an interesting topic that spans all EV’s really.
As far as I know there is no abs active under kers so if grip is lost the car will skid - but I’ve never actually had this happen, so I can’t confirm this from my experiences. The first part of applying the friction brakes (I think) applies some kers initially then the friction brakes take over if more brake pedal pressure is applied (again this may vary depending on the set up/model).
There has been much debate about using regeneration in slippery conditions. The general consensus appears to be to set it to a low (or turn it off if available) regen level if very slippery.
GoodIn fact I can't be assed with an argument over this so fill you boots, say what ever you want I'm out
Interesting concept though - it doesn't operate ABS by pulsing brakes, but should prevent wheel lock in it's own way. (albeit not one I would be relying on in icy conditions!)NO it doesn't operate the ABS or Traction control
I don't think the original question was a binary, either/or concept - at least not to me anyway. It felt more analogous to using engine braking in an ICE car vs the brakes - but not to the exclusion of them.OMG, I really didn't know that!! ever day is a school day......maybe I'll get a few eggs and suck on those, so your happy to use KERS only in snow???ice, forget about the ABS, traction control, small little things like those safety devices????
I'd read the same somewhere, that higher levels of regen can cause locking up of a wheel in very icy conditions - the same as strong engine braking can. I suspect, since KERS seems to be quite variable in strength based on battery temperature, charge level, speed, etc - combined with tyre traction due to road conditions and tyre abilities - and variables on a model to model basis too - then either experimenting in a safe location, or setting to minimum, might be wise.This is an interesting topic that spans all EV’s really.
