Extra bit on accelerator?

[Christophe]

I know this was spoken about a while back but cant find the thread.

I noticed that if i pressed hard enough the accelerator pedal went furth by like a click. Is this meant to happen? Does it do anything? I tried various things but didnt seem to make me go quicker.

sorry if repost

I'm pretty sure it's a button to cancel the cruise control if you have it...

 

[kully]

cups have the click extention .... for warp drive iirc

 

[Christophe]

o right mine 52 172 ff. i dont have cruise control like

 

[Darren S]

I know exactly what you mean! Only seems to be noticable if you're giving the car some beans?

Hopefully someone has an answer. My m8 Steve almost has an obsession to find out what's causing it?

isn't that going against all Cup logic and adding extra weight

I don't have CC either but I still got the "button"

 

[kully]

go faster pedal

 

[bmh.01]

Overrides the speed limiter function basically.

 

[HartZ]

I always wondered what this did too!

 

[Ian_182]

FPMSL at some of the answers

yeh, if you use it at 139mph you can go a little bit faster....

 

[@Spoonie]

Do people not read the manual that comes with the car?

 

[Gumby]

Is it not just so they don't have to make 2 pedals, thus saving a lot on design and manufacturing costs?

 

[Ian_182]

Isnt it just a piece of plastic to stop your carpet wearing out

 

[bmh.01]

Do people not read the manual that comes with the car?

After reading most of the thread on here, i've come to the conclusion that not many do :S. God knows why not.

 

[StevieGreenstuff]

Had a good look at Darren S's Car, it happens before the pedal gets to the carpet stop; my cable-throttle ph1 has a carpet stop, but no click.

I see why some are saying cruise conrtrol overide but; Shouldn't this be operated by the sightest touch of gas or brake? Lol at folks slamming the gas on because there's traffic ahead?

I have experienced the 'click' in Darren's car myself, when driving ethusiastically (cruise control was off iirc).

It seems to only let you get past the click when your giving it some, but as a result of squeezing rather than mashing the gas pedal. It's perma-free whilst the car isn't running, but only seems to be operable with the engine running when already at high revs... But we can't see what the point of it is?

Does anyone have a definitave answer?

It is to turn the speed limiter off.

The manual refers to it as "kick-down".

If you quickly need to speed up you push the pedal firmly past the "kick down" point to disengage the speed limiter.

Get in the car, put the speed limiter on to 25 and reach this speed, now push the accelerator to the floor, clicking the button under the pedal. You'll find it overrides the limiter in case of emergency.

Thats what its for. Thread closed.

 

[StevieGreenstuff]

If that is what it is it sound a tad dangerous to me?

What kind of an emergeny system requires full throttle travel?

 

[@Spoonie]

How the f**k can it be dangerous?

 

[Ian_182]

I thought in an emergency you should stop.Not go faster.What situation would you use this for

 

[@Spoonie]

Moving out the way of fast approaching vehicles (Police, Ambulance) when you can't pull straight over, i.e Motorway.

 

[StevieGreenstuff]

How the f**k can it be dangerous?

Because when the sh1t hits the fan you need measured inputs. Being as the throttle is FBW the slightest touch should override it, as should the slightest touch of the brake; mashing the throttle to turn off the cc is a bit like taking a howitzer to a fencing match.

Also, if this is the definative answer, why is it that it's sporadically operable when cc is not engaged? Surely the click would either be permanantly there and just ineffective, or never accessible uless cc is engaged?

Why are you so bothered about what I see as quite an interesting nuance, so much so that you declare the thread 'closed'? Have I pi55ed you off in a former life?

this is renault we talking about dont forget.

If that was neccessary then turning it off with the slightest touch would give you full control from the off.

What if, for non emergency reasons, you just want to smoothly accelarate round slower traffic, Do you have to do that at full throttle too?

I guess they were right when they said driver aids would remove all control from the driver.

Its got nothing to do with cruise control. No you haven't pissed me off, I just can't believe people don't read responses fully. I've clarified it below.

 

[@Spoonie]

Right let me clear this up, there are two functions on 1 switch

Cruise Control - Shows green on the dash when activated, speed can be increased/decreased with +/- on the sterring wheel. This is overriden by touching the pedals or switch off via switch or 0 on sterring wheel.

Speed Limiter - Shows orange on dash when activated, max speed can be increased/decreased with +/- on the sterring wheel. Speed in still controlled via accelarator and can be overriden by depressing the accelarator pedal fully down (OP original query) or by pressing 0 on sterring wheel

WTF you going on about? Its got nothing to do with cruise control.

Ok so replace the term 'cruise control' with the term 'speed limiter', and reread. Surely the same points still apply. Also, the fact that I may not have appreciated your point exactly doesn't mean that

a) you'r answer has not covered all the questions I have about this, so please try and understand my broad spectrum perspective. I'm not saying that it doesn't do what you say, I'm just wondering why it has all these other, seemingly at odds, characteristics.

and b) why you're taking this so, er, so personally. Are you the reno design engineer responsible for this system? Am I having some kind of go at you, when all I'm saying is I'm really quite curious about what this pedal is all about?

If all it does is what you say, it's function could easily be performed by a throttle position sensor; creeping increases in position could be ignored, anything the ecu saw as a definative or deliberate would overide it.

So why all the complications to it?

S.

 

[16vMK2 to 172Sport]

omg! what a mess some people get them selves into, they dont understand so they have to persistantly talk bull - just accept the answers that are given. I was going to explain what "the click" did but the last couple posts made me really not bothered lol

Ok, Please post your questions and I will try and answer them. Ignore cruise control as it has nothing to do with this. Sorry if i offended.

do you understand the concepts of 'cruise control' and the 'speed limiter'??? do you know what each actually does?? because i think that why your gettin confused

I don't think he does as he mentioned over-riding with a slight touch on the accelarator.

Actually this kind of speed limiter does exist in all cars, its called a foot...

 

[StevieGreenstuff]

It's not a mess or talking bull, I just really want to know.

as to why I don't just accept the answers given; I wouldn't design a sytem like that. And in an emergency I'd want full control to be restored to me from the off.

At leat I'm not dismissing the other guy out of hand, which seems to be what you seem fit to do to me. I know I'm dragging this on a bit, but I'm tying to be +ve. If you don't like me asking the ultimately incosequentil questions I am, feel free not to make any comment at all. Suggesting I don't understand just because I'm saying I don't thing the system (as it's being presented) is any good is a bit of a cheap shot.

Any action by the driver should turn these systems off, surely, until you'r happy to turn them off again?

So no, I don't understand, which is why I'm asking the questions...

S.

 

[@Spoonie]

What do you want to know? The button under the accelarator, when pressed, overrides the speed limiter function. Thats all there is to it.

S.

Are you familar with how a speed limiter functions? You still have to depress the accelarator to move the car. When you hit the desired speed you do not accelarte anymore. If you take your foot off, it slows, if you brake it slows. However if you needed to accelarate above your limited speed you need an override. This is acomplished by fully depresing the pedal to click the button. You could switch it off manually then accelarate but in an emergency this may take too long.

Cruise control allows you to maintain a contanst speed without using any pedal. If you touch them it overrides.

Can't really expalin it any better.

Right, Ok, totally clear on that, and given the difference between maintaining constant speed, and limiting speed, I guess it would do that job pretty well.

I guess wasn't seeing the wood for the trees (a little bit) there.

So the questions I still have are;

Why does it operate infrequently when under 'normal' driving? ie why does the car let you access it at other times and not others?

With reference to above, why is it only when the engine is at high rev's? If the unit was faulty it would happen indescriminately. I found that you can't always manipulate the switch to 'click'?

 

[@Spoonie]

Actually this should answer your questions, to deactivate these driver aids:

Speed Limiter:

1. Switch off completely via the main switch
2. Press the 'O' on the O/R steering wheel control
3. Fully depress the accelarator pedal to press the switch

Cruise Control:

1. Switch off completely via the main switch
2. Press the 'O' on the O/R steering wheel control
3. Depress any of the pedals

I hope this helps

Not really sure what you are referring to here?

 

[MarkCup]

Me neither. My Cup has this clicky bit at the end of its travel, it's always been there from new.

Someone on here almost got rear ended by an HGV from not reading their manual about this...

They'd set the limiter to 30 mph for residential streets. Get to junction with 60 mph limit, pull out in front of rapidly approaching HGV (hey, it's a Clio 172 so no problem). Put foot down to accelerate, but stops at 30 mph due to limiter. All the time HGV travelling at 56 mph is closing fast.

In that situation, you want full throttle PDQ, so the button being at the bottom of the throttle pedal's travel is exactly where it should be.
