Toyota Hearlings on CNN Video on Internet

Sounds like we have another MBA problem here. LOL. Funny how those MBAs have been involved with so many problems lately--hedgefunds, swaps, derivatives, oil futures... Hey, these guys do know how to make money...at somebody else's expense.

 

NOtice also that Mr Toyoda wasn't going to appear until the Chairman, Mr Towns, 'invited him to appear'.

This is grandstanding by the congress critters for facetime in an election year. Now when they return to their districts they can point to this and say..'See what we did for you....'

 

I'm currently watching the hearings that are currently going on: C-SPAN3 Live Stream - C-SPAN
Its VERY interesting and I watched the entire broadcast yesterday. These Toyota people sure are getting hammered..

 

It's sad when Rep. Darrell Issa appears to know more about the Toyota electronic throttle control system than the Toyota senior mgmt testifying today.

 

Great, my Prius is now worth about $1000 less

 

The entire thing is pointless grandstanding for the public. Nothing technical gets solved by these hearings (or any such hearings really). Just soundbites for the media.
I'm still waiting to see some real science instead of emotional testimony. Both on the UA issue and the Prius brakes. Why is this so hard?

You shudda bought TM stock on Monday. It jumped almost $3 today. 1000 shares wudda made ya $3000 in one day.

Oh, btw, if you don't sell your Prius anytime soon and if you didn't buy TM stock then you neither lost any money nor made any money. Food for thought.

When I sell or trade in my Prius in 3-5 yrs I know how much it'll be worth ... ~ $500. Today means nothing.

 

But if you're more likely to buy another Toyota before you sell one... it's all good!

 

So these people never heard of interface chips with multiple
A/D converters on one die. It's industry-standard, and done all
the time. Now these lunkhead politicos think that to be safe,
every signal into an ECU has to have its very own physical chip
die or it'll mix up all its inputs. Nice going, that'll have
a great impact on the packaging industry, won't it.
.
The best that can come out of this is for "gilbert" to become
a household word meaning "I shorted wires together that shouldn't
have been, oops".

I love watching Hearlings on CNN.

 

Does it work on a fail safe system? One die, 1 power supply route! To be truely fail safe, everything should be duplicate physically including the PCB. (Just like you will not do a mirror on two partitions on a single hard disk.) When it die, everything go with it.

 

Yeah, if only I had a loose $71,000 to dump on the bet!

Absolutely. That's why I want 2 of everything. In fact, duplicate me and put me in a duplicate car driving in a parallel universe. Just to be safe.

Every engineering problem is solved with compromise. Then each and every compromise is very easy to 2nd guess by anyone not involved in the original work. I've been on both sides of that and it REALLY sucks trying to explain MONTHS of work (years in this case?) to some flunky who's got 10 minutes to listen. Who will then not understand it and give a 1 minute summary to another flunky who will answer questions at a congressional hearing.

The GM owners at the beginning of this thread made it sound like Toyota admitted to electronics problems, when all I find from news sites is that they're "still investigating the issue, including whether electronics of the gas pedal system might be at fault, but the company has not found any evidence of that yet".

CBC News - World - Recalls might 'not totally' fix Toyota problems: president"
They're saying that the current recalls "may not solve all problems" - does anyone really expect a guarantee (because that would be a really stupid thing to say on record!)

For the guys complaining that their 2010 is devalued - you should have left it parked at the dealer if you were worried about depreciation!

GM Fined For Slow Reporting Of Defects (washingtonpost.com)

When GM's product regularly falls apart ... folks expect it. It finally dawned on me why the media got so mad at Toyota ... they made such better stuff, for so many decades, that the public feels they have a RIGHT to be angry ... after all Toyota isn't GM ... Toyota is EXPECTED to make perfect cars. Sadly, the reality check came ... and people realized their Toyotas might not be an infinite number of times greater than GM quality that they presumed after all these decades.

 

No, that is not necessary, only the essential items required a fail safe system.

 

Right, isn't the driver an essential safety feature of the vehicle? Duplicate them! If one croaks then their copy is ready to take over.

Yes it's a silly example meant to point out silliness. The engineers have to make rational decisions about how far to take redundancy. Your mirrored hard drive example is perfect. Sure you can mirror two physical disks, but then what if a university professor shows how a sledgehammer can still make the server crash? Well obviously that server should have been clustered for better protection! It can go on and on.

I'm not saying the Toyota system IS redundant enough, I have no idea. Because it hasn't been explained well enough for anyone to make an educated call on it. I just think it's way too easy to come out and say "it isn't redundant enough" or make any claim really, when we don't know jack. Prof. Gilbert's findings based on only 3.5 hours of study haven't been peer reviewed, no explanation of how his induced condition represents real world possibilities has been made and yet he's allowed to present these "findings" in a congressional hearing? Way too preliminary for this arena.

Sorry, let get it straight. It was Toyota claimed that its a fail safe system. A system with essential sensors output mismatch and failed to generate an error signal is not very fail safe. It can only be described as "If it doesn't fail, its safe!"

 

I gathered you must have been sold by Dr David Gilbert's testimony.
Let see if anything more comes out from his advise.
