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

Tell ya what, you give me a good citation on whatever Honda
is proposing be flown-by-wire, and I'll give you meaningful
commentary.

So far, I think people haven't any clue as to what's under
consideration here.

 

Indeed, one of the reasons I demand a manual transmission.

You're partly confusing two different things, the fly-by-wire i.e. no
mechanical link, and an automated control system. Not really the same
thing although the fly-by-wire makes implementing the automated control
easier. If it's a simple electronic replacement for a mechanical link
(with suitable redundancy) it's ok with me. Automated control trying to
second guess my decisions based on far less sensory input than I have,
is not ok with me.

The hydraulic steering on a lot of tractors and construction equipment
that was noted by another poster is a good example of basic fly-by-wire
or in this case fly-by-oil technology. It makes no attempt to second
guess the operators decisions and simply replaces what could be a very
complex mechanical linkage with a couple of nice flexible hoses.

The hydraulic brakes in cars is another even earlier example.
Brake-by-oil basically, and we still require the mechanical cable
operated backup system in addition to the split hydraulic redundancy. Of
course in recent years they've added the automated control a.k.a. ABS to
try to second guess the operator.

With the electronic throttle control servo failing in the WOT position
and ABS second guessing your braking, you would likely have gone right
through the garage, both the front door and the back wall.

Nice try. You obviously, regardless of gender,
dont understand how to relate parallels.

To categorically reject change because the "current system

I give you the pick-up and the platform frame SUV built on chasis and
suspensions from 1950 that all the people in the country have flocked to
dealerships like sheep and plunked billions of dollars on and to which the
automobile companies have spent next to nothing on in technology.

The idea of full-on "steer by wire" with NO mechanical backup is STUPID.
Throttle-by-wire is questionable, but at least not outright stupid, and
has some quantifiable advantages (throttle modulation during automatic
transmission shifts, more graceful over-rev protection, etc.) Full-on
steer-by-wire has no redeeming features to anyone except the automaker.
Not to the driver, not to the passengers, and not to other users of the
roadway who had sense to buy cars without steer-by-wire.

That said, I don't know of any true "steer by wire" systems on the road.
If Honda has "electric steering" I would hope and expect that its really
just an electric ASSIST steering system.

So it is a misapplication of the drive-by-wire term to electronic

They acutally call it "Drive-by-Wire Throttle SystemT"

I believe the Chevy Malibu has a steer-by-wire system.

I doubt it, seriously. To my knowledge, concept cars
are the only vehicles that employ steer-by-wire.
