Toyota + Drive-By-Wire = bad idea?

People seem to think drive by wire is new.......it's been on tons of luxury vehicles for quite some time.

And where is the uproar about sportbikes with it?

Sorry but cable throttles will eventually become obsolete.

You are using a crash that happened over 20 years ago as evidence? It also doesn't make much sense when you consider the A320 series (fly-by-wire) has a better record with their controls than the 737 (not fly-by-wire) it competes with. The 737s rudder problems resulted in several crashes.

You usually have multiple layers of redundancy built in to make sure that any damage or failures can quickly be compensated for by switching to another control line. Where as with mechanical, if something breaks it stops working unless you have a back up system in place.

It's hard to say though, both have their advantages and disadvantages. Just so happens that Toyota's mistake will shed a bad light on electronic control systems doing your job for you.

I agree completely. I was simply pointing out that particular example Avatard provided was a poor one.

Electronic throttle control using redundant accelerator pedal sensor is a result of stringent emission regulation.

The 777 is fly by wire and I have yet to see any issues with it and that plane is almost 15 years old now. There are several newer models of airplane that are performing well using fly by wire. Shit, even Yamaha is using fly by wire technology in their motorcycles now. As long as there is redundancy in place in case of a failure, you'll be ok.

Yeah, just add "check is in the mail" and "I won't come in your mouth", and you have a real "triple crown" of promise.

I'm reassured :whistle:

A good record is better than reassurance. You choose to ignore both.:shrug:

[Avatard]

I don't ignore shit. For instance, I've noticed in my lifetime that complex electrical shit invariably fucks up (sometimes, in less than a year's time), where simple mechanical shit from the 1900s still works flawlessly even today.

You can fly in whatever shit bucket you want. I personally like vehicles where the controls are attached to....well, the control SURFACES.

[goof2]

You can believe whatever you want. The fact is that people on average drive more miles in their cars and own them longer now than they did when everything was mechanical. They aren't doing this because the cars are less reliable now.

As for passenger aircraft, it would be impossible for a person to fly a larger passenger jet without assistance from electrical systems. Unless you are flying in Piper Cubs you are pretty much dependent on electrical systems to work the control surfaces.

How do you feel about the F-16 Falcon?

[Avatard]

How do you feel about the F-16 Falcon?

Never owned one.

Lame -
Pulling the F-16 card is so hipster.

You are failing to take COST into the equation. I can assure you that if price is no object, electronic components would and could last a lifetime.

True, a space grade hermetically sealed highly quality controlled relay costs $100+ while an automotive grade relay that does the same thing is a couple of bucks.

I know....but I had to ask it. That's just how I roll.
