Is there a petrolhead in the house?

Electronic Stability Program on your car. What does it actually do? I ran for a while with it on, then for a while with it off. Couldn't tell the difference.

Can anyone explain what it is supposed to do?
 
Usually that is skid control, if the driving wheels are going to wheelspin it slows them down so they do not lose grip.

Different carmakers call it different things.

Or of course it could be some kind of suspension control, perhaps stopping the car from rolling in the corners.

I don't know. Check your manual.
 
Allows you to steer sharply in emergencies by braking each wheel independently so as to better enable the car to follow the steering direction of the driver rather than skid or flip to an undesired location.

Right, so it is a ' save your arse ' mechanism. That explains why there is no discernible difference between off and on in normal road driving. Thank you.
 
Yeah it's for those moments when a 20 tonne concrete block falls off the lorry in front of you on the motorway, and you need to steer round it rather than spin into the central reservation.
 
It actually stands for Extra Sensory Percetption, it allows your car to predict what you wanted to do and do it even though your fallible human body failed to communicate this properly. You didn't notice the difference since you're already one with your machine.

The next question would be 'are there any situations in which you might be better off with it switched off (if your car allows it)'. Can't think of any myself... perhaps if you are messing around in a race track or rally circuit.

I had to turn it off when trying to do a hill start on compacted snow last winter, I was steering to get grip but it seemed to think I needed some braking.
 
I didn't know the Austin 7 came with ESP.

It uses solid-state accelerometers to detect anomalously high levels of dγ/dt (rate of change of yaw angle) and then selectively brake different wheels to recover the situation.

Utterly cunt you at times when you least expect IME.

you slide left you correct it and then the ESP or ASM (active stability management) kicks in and over corrects your correction causing you to spin. EVERY time.

It presupposes that you as a driver will not react to a situation and attempt to steer out of it and attempts to control the car's direction by use of abs/cadence braking and steering increments with suspension changes in order to change the weight distribution over the wheels...

which is great in theory, the reality is we all react behind the wheel and it makes the car kangeroo about in really unexpected ways which for an experienced driver is bloody hard to control and correct but for someone with the more usual standard driving knowledge/experience/skill it will always lead to an accident, I cannot for a second think why this still infant technology ever got past the safety audits...

leave it off unless you take your hands of the wheel in cases of skidding in which case return your licence instead and use a bus...

GLC - such a fantastic driver, he knows better than every major car manufacturer in the world. Sure, they make millions of cars a year, and sure, accident rates continue to improve as car safey does. But you've driven a Bently damnit, what do they know!

ok clown shoes...

in which case why isn't it fitted to GT cars, F1 Cars, F3000 cars etc etc etc... people who've got car control because they've stuided the craft will turn it off every time. people like you who clearly can't tell there's a significant difference should leave it on... if only so you're pitched into the wall...

here's a non-obscure you've been searching for an hour after the comment to vindicate your ad homine attack link...

http://www.autocar.co.uk/blogs/stillatthewheel/archive/2011/02/10/170498.aspx

why would it be that autocar that well known and respected journal would say ... exactly what I have about when to switch off or not...

fuck me you're a thick cunt...
 
No theyre not.

They've said if you want your car to slide it needs to be turned off. I've said in a slide the car kangaroos around with it on. How is that different?

Tell you what let's get an Alfa 157 with ESP and well take it round a set course in say Milton Keynes and we'll do 2 circuits with it on and 2 with it off. After you can decide which set you preferred for ride quality.

It'll be the 2 with it off. Guaranteed.

I thought we were talking about driving on public roads. Do you do much sliding on the motorway?
 
When Clarkson drives the unobtainable supercar he likes to turn off traction control so he can drive slowly round the track spinning the rear wheels, quite childish really but it seems to be the only way he knows.

It is noticeable that when the Stig is trying to do a fast time in the same car, there is no NO wheelspin apart from off the start line and he does not get it sideways in the corners. In fact his style is so far removed from Clarksons as to be totally different.

Other than the other day when a brick went through the window at 70 no!!! Not often.

Hence mk suggestion lots of low speed roundabouts which simulate this even at 40. I've done it. I've experinenced it. Someone with limited advanced driving skill would not Handle it well. Largely because it takes control away from the driver at critical points and unbalanced the car.

The Stig does wheel spin. And has it turned off.

Clarkson is a terrible driver

Because the rules don't allow it

Autocar is a consumer magazine, not a peer reviewed journal. Nevertheless, there's what that article has to say on the matter

Yet ESP systems, good ones like those you’ll find in any VW, will prevent that accident from happening at all quite often.
Click to expand...
the system is so good as it stands that it makes a full blown spin a virtually impossible thing to achieve, even in the snow

around the Nurburgring last year, with none other than Hans Stuck at the wheel of our very own Scirocco R, ESP was no less than 100 per cent necessary. Without it even the great man himself might have been in trouble on a couple of occasion

Which is to say, it dosen't support your argument at all

Ahem.

Here's my post

And here's yours. Rather below ad hominem, which would be along the lines of "you're wrong because you're a cyclist"

yes surprisingly... had anyone been in the passenger seat then that would have been another story entirely... fell off a lorry I think Just before it hit it bounced off the side of a people carriers door and went in through the passenger window. I have enough time to think did that just drop from that ca... smack... then the entire window blow out!! the bloke behind started flashing and honking... that'll teach him to be too close!! :D coasted in to the hard shoulder and then inspected the damage then carried on.

Doubled the cost of my MOT tho having to replace the glass... other wise I'd have gotten away with a new hand brake cable. and of course had I not being goign to the MOt station I'd have not even been using the car!!! FML sometimes... :D

I've had a broken windscreen in the days when they went opaque, quite a frightening experience. The second time it happened was on the Autobahn, but I had pulled onto the hard shoulder before it actually disintegrated.
