ive had this in a van for the last 5 months. Might be ust chrysler's
system, but it doesn't work too well for me, still get a loud tyre
squeal if I floor it to merge traffic. Nowadays I just turn it off
when I start the car.

i HATE this. Teach proper braking practice, not compensate for driver
inadequacy. i remember a few news stories from the UK a few years
back, where these kicked in uneqpectedly. guy tapped hi brakes because
he saw a speed camera ahead, just to chek his speed (as we all do) and
the thing did an emergency stop, causing a 3 car accident (car was
turning at the time). There were another case or two as well.
Until the car can sense the situation around it (not easy or
praticable) it should NOT have overriding command of motive systems.
Thats just plain common sense.

see your headlight switch - wire the first stop, so it'll also be
triggered by the ignition. if key's at II, lights are on - much better
than that stupid way saturn has of working off the handbrake -
friend's vue has its DRL going off every time he stops 9its a manual,
and he is n a hilly area, and drives properly, with handbrakes at
lights etc) volvo did it right years ago. if you use your regular
lights for daytime running, you don't need all the lights and
reflectors etc. just run from the ignition.

i wouldn't. I've not even a big ABS fan. i guess the problems is that
mostly these featurse are not set up as 'emergency' but as
'cautionary'. So they're on be default, and set to activate much too
soon. Of course, there are SOMe safety features I'd love to see
introduced into the UK thats been standard elsewhere for years. REAR
fog lights, for instance. Oh, and seperation of brake and turning
signals. removal of turning signals from being buried in with
headlights (see certain neons, and current crown-vics for instance.

Don't get me wrong, I'm no luddite 9in fact, quite the opopsite) but i
do know where technology should not be substituted for driver
shortcommings. instead of whacking more tech on, hold the drivers to a
higher standard.

That's the only way it can work. It's based on an ECU and a bunch of
sensors.

Erm... well yes. Stability protection cannot assume you're using standard
suspension and tyres on a dry road surface. If you replace your tyres for
el cheapo ones, it doesn't need to be told, it figures it out by itself. :-)

Spot on. Experienced drivers do it to. It's very hard to apply the right

Yes, but for 99% of drivers, 99% of the time, airbags, stability protection,
ABS, EBD and EBA is additional weight and cost. Sure, when needed it's
great. I can only think of one occasion when ABS was genuinely useful in
helping me avoid something under heavy braking. It doesn't help me stop, it
allows some steering control when braking hard... but it doesn't prevent a
skid if you brake and steer at the same time.

Traction control is the same. You can still wheelspin with traction
control.

Those cars I've driven with stability protection, they vary. BMWs allow
some oversteery antics. Mercedes don't. But you can still skid off the
road.

Airbags? This Accord (waves to Accord sat outside the house) has four
airbags (and a broken SRS module but that's something else). My last
machine was written off (www.dervman.com/kd57.htm) and the airbags were not
needed, thus not used. They sat in their housing for nearly five years and
when the car was lunched into a roll then hit the kerb, they didn't
deploy...

Some systems are designed to prevent oversteer in corners, but nothing can
overcome the basic laws of phsyics. For the system to work you have to skid
a little, that's how it spots you're skidding. Some tyres make a louder
racket than others.

The system is not triggered if you "tap the brakes." If you aggressively
punch the pedal then it triggers, but as soon as you lift off, it lets go
too. It uses a certain element of logic too, working on what your other
controls are doing, what they've just been doing, how much force and how
hard you push the pedal, so on and so forth.

Tapping the brake pedal doesn't trigger it. You have to jack on the anchors
with lots of force.

Actually if the guy was an idiot and was hammering along then punched the
pedal, he caused the crash in conjunction with the other chuffs behind.

It doesn't. It augments what the driver does.

I've played with all sorts of electronic systems. Some can be fooled pretty
easily. Accelerate hard then brake firmly and the Mercedes EBA is
triggered. Tapping the brakes doesn't trigger it.

One problem with this solution is power consumption, which in turn is linked
to fuel consumption. Running 110 watts of bulb uses up more than running 24
watts of bulb and does make an appreciable difference to motion lotion.
Thanks to the wonders of carbon credits, every part mile per gallon is
starting to count.

And the other issue of wearing out the wretched things. How many Volvos do
you see with one headlight working?

I agree, but I suspect we both know it's not going to be possible to achieve
this.

As for ABS, two sides of the coin. On the one hand, yeah it keeps you
pointing in the right direction when you stand on the brakes. On the other,
there are idiots that believe it shortens their stopping distance and thus
tailgate and drive too fast.

Way too many British people don't have the foggiest on how to use high
visibility lights (front fog, rear fog lamps). Some idiots put *everything*
on either to look cool or at the merest hint of rain. Other chumps keep
everything off until it's dark...

Some systems are designed to prevent oversteer in corners, but nothing can
overcome the basic laws of phsyics. For the system to work you have to skid
a little, that's how it spots you're skidding. Some tyres make a louder
racket than others.

The system is not triggered if you "tap the brakes." If you aggressively
punch the pedal then it triggers, but as soon as you lift off, it lets go
too. It uses a certain element of logic too, working on what your other
controls are doing, what they've just been doing, how much force and how
hard you push the pedal, so on and so forth.

Tapping the brake pedal doesn't trigger it. You have to jack on the anchors
with lots of force.

Actually if the guy was an idiot and was hammering along then punched the
pedal, he caused the crash in conjunction with the other chuffs behind.

It doesn't. It augments what the driver does.

I've played with all sorts of electronic systems. Some can be fooled pretty
easily. Accelerate hard then brake firmly and the Mercedes EBA is
triggered. Tapping the brakes doesn't trigger it.

One problem with this solution is power consumption, which in turn is linked
to fuel consumption. Running 110 watts of bulb uses up more than running 24
watts of bulb and does make an appreciable difference to motion lotion.
Thanks to the wonders of carbon credits, every part mile per gallon is
starting to count.

And the other issue of wearing out the wretched things. How many Volvos do

I agree, but I suspect we both know it's not going to be possible to achieve
this.

As for ABS, two sides of the coin. On the one hand, yeah it keeps you
pointing in the right direction when you stand on the brakes. On the other,
there are idiots that believe it shortens their stopping distance and thus
tailgate and drive too fast.

Way too many British people don't have the foggiest on how to use high
visibility lights (front fog, rear fog lamps). Some idiots put *everything*
on either to look cool or at the merest hint of rain. Other chumps keep
everything off until it's dark...

It's got everything to do with how risk-averse you are, how lucky
you feel, how often you do stupid things on the road, etc.

I'm only too happy to make a modest investment that might one day
save me from my own stupidity, and just as happy when those same
safety systems are never employed.

I'm especially happy to have them so that I can also be protected
from the stupidity of other drivers, too distracted by cell
phones to stop for stop signs or traffic signals.

A few years ago I was driving around Providence in a 25 MPH zone
and approaching an intersection where the cross street traffic
had to stop and I did not.

Just before I entered the intersection a driver flashed thru it from my
left doing at least 45 MPH. The 1990 van I was driving had NO airbags
and would not have been able to avoid the accident if I had gotten there
a couple of seconds sooner. If the situation repeats itself and I'm not
so lucky next time, I REALLY want the extra protection!

The first car I had with 4-wheel disc and ABS was a Nissan
NX-2000. It was a cute little red car, and occasionally my wife
drove it. One day a truck blew through an intersection and she
had to stand on the brakes and swerve all over the place to avoid
being hit. But she did it, largely because of that hammering
under the brake pedal combined with the excellent maneuverability
of that little sports car.

thats the point. it was a system fault. Wouldn't, couldn't happen with

read what you just said. It augments. how does it know it needs
augmenting. can it see why you're slowing? no, it can't. Right below
this you yourself say how you can fool these systems. If they can be
triggered into reacting inappropriately, why would you call that a
safety system.

We have a driver, a control system that samples the data all arond the
vehicle 9or is supposed to) and makes edcisions based on whats going
on around the vehicular unit. Is the car dong the same? if not, how
can it tell if the braking force needs 'augmenting'. Friend of mine
was involved with the Darpa grand challenge. one of the problems they
faced was braking - getting the braking force suitable for the
enviroment. it all depends on how far you have to stop, if you intend
to stop or just slow down, is avoidance needed, what surface you're
on, how you're loaded. no car on the market can tell any of that. It
could tell the mass you're carrying, but is that load in the back a
wardrobe, or half a tank of tropical fish, or 10 8ft sheets of
plastic. Are you stoping because there's a child just run out, you've
just spotted a cop with a radar gun, or the lights you were hoping to
make just turned red. Is it rainy, there snow, or sand on the road. If
it can't tell, how can it adapt. I could be braking, be just shy of
the braking limit for the conditions, but EBA thinks I meant to break
harder, so it presses harder, oops lockup, now thats the ABS kicking
in, thats longer stopping, less control, all for a system that think
sit knows better.

Dangerous? I should cocoa.

not when its working 100%. If you've lpayed with electronic systems,
you shoud know they're some of the most tempramental and fragile
things out there. They're also good at going wrong and giving no hint
of it until its too late.

Great, you assume the headlight bulbs are the ones used. not so, I
said the firststop. in the Us, thats the orange 'running lights', as
you should know the volvos in the UK used those small 11W sidelights.
dipped beam is the 55W elements, which are the second stop on the
headlight rocker. As a brit, i'm sure you appreciate the difference
between them - turn your lights on, turn the ignition off, and take
your keys out - should just be your sidelights that are left on.

nope, doesn't keep you opointing in any direction. it just increases
the chance that you will be able to steer. in many cases, ABS won't
stop you sliding at all. in some, it'll actualy make you spin.

again, as I said, don't use technology to compensate for stupidity.
The only way to beat that is education.

thats the point. it was a system fault. Wouldn't, couldn't happen with
standard brakes, can with the EBA stuff. THATS the point.

read what you just said. It augments. how does it know it needs
augmenting. can it see why you're slowing? no, it can't. Right below
this you yourself say how you can fool these systems. If they can be
triggered into reacting inappropriately, why would you call that a
safety system.

We have a driver, a control system that samples the data all arond the
vehicle 9or is supposed to) and makes edcisions based on whats going
on around the vehicular unit. Is the car dong the same? if not, how
can it tell if the braking force needs 'augmenting'. Friend of mine
was involved with the Darpa grand challenge. one of the problems they
faced was braking - getting the braking force suitable for the
enviroment. it all depends on how far you have to stop, if you intend
to stop or just slow down, is avoidance needed, what surface you're
on, how you're loaded. no car on the market can tell any of that. It
could tell the mass you're carrying, but is that load in the back a
wardrobe, or half a tank of tropical fish, or 10 8ft sheets of
plastic. Are you stoping because there's a child just run out, you've
just spotted a cop with a radar gun, or the lights you were hoping to
make just turned red. Is it rainy, there snow, or sand on the road. If
it can't tell, how can it adapt. I could be braking, be just shy of
the braking limit for the conditions, but EBA thinks I meant to break
harder, so it presses harder, oops lockup, now thats the ABS kicking
in, thats longer stopping, less control, all for a system that think
sit knows better.

Dangerous? I should cocoa.

not when its working 100%. If you've lpayed with electronic systems,
you shoud know they're some of the most tempramental and fragile
things out there. They're also good at going wrong and giving no hint
of it until its too late.

Great, you assume the headlight bulbs are the ones used. not so, I
said the firststop. in the Us, thats the orange 'running lights', as
you should know the volvos in the UK used those small 11W sidelights.
dipped beam is the 55W elements, which are the second stop on the
headlight rocker. As a brit, i'm sure you appreciate the difference
between them - turn your lights on, turn the ignition off, and take
your keys out - should just be your sidelights that are left on.

nope, doesn't keep you opointing in any direction. it just increases
the chance that you will be able to steer. in many cases, ABS won't
stop you sliding at all. in some, it'll actualy make you spin.
