if you have hydraulic or air brakes, and most us have for at least 50
years, you have no direct mechanical linkage.

Hopefully, you have your answer but if not -

Drive by Wire typically refers to the electronic connection of the gas
pedal to the engine - so when you push down on the pedal, it sends a
signal to the engine control computer than you want to speed it. The
control computer then uses a whole series of inputs to determine how
to adjust the engine to meet your request. There isn't any mechanical
connection to the engine from the gas pedal. This is noticeable, for
example, when using cruise control - a DBW system won't cause the gas
pedal to move as the engine speed changes to maintain the cruise
setting. My Audi A4 has this feature.

Electric (or electronic) power steering simply replaces the hydraulic,
engine-driven power steering pump with an electric pump that doesn't
require being hooked to the engine. The steering is still a direct,
mechanical connection, so that if the pump fails, you can still steer
the car (albeit requiring much more force). I don't know that any cars
currently made have a non-direct mechanical connection between the
steering wheel and the front wheel, and would be VERY surprised to see
that happen in the near future.

wow, cheers guys, look like i started something there, didn't I? lol

Thanks again I now have a little more understanding :-)

Thinking of buying a used 2.2 Diesel and noticed this wording and never seen
it mentioned before.

Does anyone have a 2.2 accord? Your comments on the vehicle i would
appreciate....

thanks again by the way...

yes,and the L1011 gets constant maintenance and checks,and has triple
redundancy in the flight controls.

Actually, the L1011 has four separate hydraulic systems.

You bet they're maintained. Such doesn't exist in the automotive world.

So, as usual you are cantakerous and take statements out of context.

Drive by wire means EXACTLY that. Kindly stick to the basics, OK?

"drive by wire" is not "steer by wire".

kindly stick to "share what you know, learn what you don't", ok?

You all sound like a bunch of bickering women.

"Drive by wire" is a term usurped from "fly by wire" in the first place,
used to refer to electronic steering control, throttle control,
potentially braking control (haven't seen anyone using that yet, but
it's only a matter of time), or any other electronic,
non-mechanically-interfaced control of a car's "drive" systems.

The term is used differently by different manufacturers as to which
system it's referring to, and indeed, probably refers to multiple
systems in some (throttle AND steering together, for example). Since
the meaning varies with the specific make of car, debating it here is
completely meaningless... same as debating whether the proper term is
ABS for Antilock Braking System, or ALB for Anti Lock Brakes, or any
other acronym for that type of system, which varies from one
manufacturer to the next.

Actually, I'll accept your description since the application "...by
wire" is somewhat generic with automobiles.

Anti lock brakes have been used in aircraft for a long time but again,
airplanes are subject to specific mandatory maintenance regimens.

of course!!!

but /nobody/ has that. and nobody /will/ have that unless you want a

most modern cars have that now.

mercedes had it [sbc - sensotronic brake control] but dropped it -
customers didn't like it. they even retrofitted back to standard/abs
brakes for cars that had been shipped with it.

Actually,jet engines have had electronic "throttle" control long before the
term "fly-by-wire" came into use.The FBW term has been used for FLIGHT
controls("steering" the AC),not engine control.

It's changing THIS YEAR;

says Mazda will have it(electronic steering control) on one of their 2008
platforms

sorry dude, it's not. there are no cars that have that. not one.
/all/ use direct mechanical linkage between the steering wheel and the
front wheel knuckles. most have power assist. assist is not electronic
control.

you could argue that about the rear of honda's 4ws they had on the
prelude back in the 80's. but it's not the real deal. the fact
remains, all these vehicles have direct mechanical linkage. in the even
of system failure or shutdown, driver has direct mechanical control.
that is not the case with any form of "fly by wire".

Having the throttle controlled by an ECU (computer) driven Servo
instead of by a mechanical cable link. Something that Honda does very
well on the S2000 (which feels like a mechanical link and very
natural) yet very horribly on my wife's '07 Si sedan (which hangs for
about 1-1.5 seconds after letting off the throttle thus turning anyone
who has a clue how to drive into a herky-jerky looking idiot... In
this case it's worse than GM's skip shift and the service techs can't
seem to find a way to reprogram it...)
