why is it called drive by wire when there's no wire?

[BlahBlahYouToo]

wire = cable?

 

[PricklyPete]

wire = cable?

electronic wire

 

[BlahBlahYouToo]

hmmm... ok.
but the term itself doesn't lend one to think that it's referring to an electronic wire.

Bluetooth? Drive by wireless?

 

[SparkyJJO]

What would you have them call it?

 

[vshah]

What would you have them call it?

drive by computer?

which is made of...wires?

 

[KentState]

It refers to the linkage between what ever adjusts the throttle and the actual throttle. So it can either be a mechanical linkage (cable, linkage, etc) or a wire that connects the computer to the throttle.

 

[BlahBlahYouToo]

What would you have them call it?

simply 'electronic throttle' (vs. cable throttle).

The term was coined before you were born.

i thought the term started out as 'fly by wire' in aircraft - replacing direct mechanical control with electronic control.

Yes.

 

[exdeath]

Drive by wire refers to replacing a direct mechanical linkage with a computer and software signal driven servo, the term came from aircraft in the 50s (fly by wire).

 

[punjabiplaya]

drive by electronically controlled servo/actuator

That was always my understanding as well.

Well, that's what it means.

Nissan invented this tech for the 2002 Maxima.

Of course they did. They have ninjas working on a technology they call "fuel injectors" as we speak. Should be amazing and introduced in the 2022 Maxima along with the VQ65.

 

[speedy2]

BWAHAHA. I love when car companies try to market something like they invented the technology.

Fuel injectors are a myth.

Hey, I saw an ad on the weekend for a 2009 Kia forte or something and the person was saying how seriously Kia takes safety and it has tire pressure monitoring. No comments about how every single car in the US in 2009 had TPMS

The term was just carried over from the military coined "fly by wire" when they moved away from mechanical linkages to strictly computer controlled, which was first done in the early 70's. There were already computers, although pretty crude by todays standards, in aircraft previous to this so "fly by computer" wouldn't really make sense. It was meant to specifically designate no mechanical linkage attached to the controls themselves, but obviously wires. Makes sense that they would carry the name over when it was brought to vehicles since the engineering community in general is pretty connected - new technologies spread to a lot of different industries etc. And of course marketing is gonna jump all over it because it's catchy.

I think when most people hear the word "wire", they initially associate it with electrical wire, and not, say, piano wire.

I'm selling Nissan stock as we speak.

The first production fly by wire airliner was the Concorde, 1969.

There were analog fly by wire military aircraft in the 50's.

The first all digital FBW airliner was the A320, 1984.

BMW had ETC on it's 1988 7 series, first vehicle mfg to offer it, and Chevrolet had it on the 1997 C5.

And I must say, I think it works pretty damn good. I like the way the electronic throttle body feels.
