Honda "Drive by Wire" question... what if the power goes out?

locking is not by design. the ability to apply it hard enough so that
it /can/ be locked /is/ by design. big difference. a locked brake does
no one any good.

 

alright I have to straighten this out. the air brakes have a large
spring that applies the brakes on loss of air pressure, on normal braking
they also use air pressure on the apply side to increase the braking
force. on a trailer with the loss of air pressure "usually" the spring
pressue is enough to lock the brakes. KB

How many layers of gold leaf are you planning on putting on that turd?[/QUOTE]

LOL, interesting turn of phrase.

How nice - so you're no longer in mine, either.

Your overreaction to my posts has been noted.

nicely put - i didn't mean to suggest that air brakes couldn't lock - i
meant to say that locking is a result, not a purpose.

Road injuries are a big problem,

What's are you comparing that to? What they were in the past?

I don't know about where you're from, but in my country road deaths
occur at about 4-5 times the rate of homicides, so there is reason to
improve saftey.

That's one way, but I doubt it will be the most effective once
technology is sufficiently developed. And it won't be developed other
than in small steps, such as brake-by-wire, throttle-by-wire,
steer-by-wire, navigate-by-wire, see-by-wire, think-by-wire.

I'm not sure about the Honda system, but the GM system allows
the computer to use the throttle to make other things that are
happening transparent to the driver. I know that the new v-8's
with the 4-8 cylinder technology use the electronic throttle to
make the shift from 4-8 cylinder transparent. The electronic
throttle is also used to "improve" tranmission shift quality.
There are bound to be all sorts of good reasons why you want
to control the throttle. Personally, as a tech that works on
the vehicles, I hate the fact that I can no longer "blip" the
throttle under the hood. I can use a scan tool to change
rpm, but there is no way, other then using a helper, to
rev the engine quickly anymore.

I also find that many of the vehicles have a very "disconnected"
feeling from the throttle. Some are better then others, so I'm
sure it's just a matter of tweaking the calibrations.

Now when it comes to "steering by wire".....I'm not sure
that I'd be in favour of that.

Depends on the surface. on loose gravel or snow, locking improevvs
baing, by packing material. Lot of the truck places here have lose
dirt and/or gravel for their internal roads, if nowhere else.

On smooth flat, clear surfaces, however, you are correct.

I agree that marketing and advertising and making a buck
play a huge role in design. I agree the outcome is most
certainly not always a better design, engineering-wise. I
could even stomach someone's argument that most design
changes are not engineering oriented at all.

But America is also a revoltingly consumer-ist society.
Which came first--the advertising blitzes pushing "bigger;
more," or some sort of instinctual drive from Americans to
insist on bigger more--is debatable.

So Americans want pickup trucks and SUVs which rarely
satisfy any physical need and are merely to keep up with the
Joneses. What's an auto company executive to do to keep food
on his family's table? So to speak.

But safety, things like better fuel mileage or more Hp
performance, are not ignored. Many improvements do lengthen
the life of a car, etc.

Honda & Toyota? Hmmm.

Yes, I know. But I hesitate to say more without reading up
on why GM and Ford has been going down the proverbial can
the last several years. I thought it was more like labor
problems: GM and Ford can't build a car cheaply. I dunno.
Someone can post a citation on why they're failing while I
guess Honda and Toyota are doing fine. 'Cause America still
loves big, gas guzzling vehicles, from what I see.

Can you point to any research that support this conclusion? I would be
very interested to see it, since all the research I have seen supports
the opposite conclusion: That driver training is ineffective at
improving
safety.

Please note that I am asking for references to actual peer reviewed
research,
not just opinion.

No...it has a regular old rack and pinion steering system.
The electric "assist" sits up in the steering column area
and simply provides the assist to a "standard steering"
rack and pinion.
