SUA - Here we go again

J.F.A.C. lets all read different interpretations into this document. The car was DELIBERATLY fooled into acting wonky, so it did! We should be surprised? If you got a TASER dart in the butt, you would suddenly accelerate too!

 

Its a good thing to do. It appears from the memo, that they simulated a sensor failure and found a bug. Now in Toyota's response they say they did a "adjustment and refinement" to correct this before production. I'm sure that they should have other documentation to say this happened. We always formally tracked these things. They may not want to give such documentation to CNN, since, well the media can blow up anything.

I would like to know if they did fix it. Toyota says the correct translation of the problem is "creep" not acceleration, and if that was the defect it hardly made the cars unsafe.

 

This was 1 of 3 anti Toyota anti Prius family reports CNN has posted since the Plugin and C models started arriving. Today's is a playground whine about the V on CNN Money. The other is a pro Volt piece with numerous unsubstantiated claims and incomplete data. (mpg in cs mode is?)

 

Tony, I took the time to look at your milage chart, and it is quite impressive. You can certainly see the yearly seasonal dips when winter rolls into the midwest. From what I recall you are pretty much a "Flatlander", not many hills to climb. Those 60 and 70 numbers are quite impressive.
I sure wish I did not have SR-2 to climb everyday on the homeward leg of the work routine. If I ever break 50 I will be amazed. My best was a 49.something, once, and never again duplicated! I usually run 44 in winter 48 in summer. That still beats the 4Runner all to hell!

Keep it up, you have set goals that I can only try to come close to, but you have proved it can be done!

 

So, how many software "bugs" have they not found....??!!

 

I always told my bosses "So far as we are aware, we have no undetectable errors"

 

Now that we have them just where they want us, lets move on!!!

 

this seems politically motivated to me.

 

This is the second thread on this CNN report.

Listen I'm not defending CNN, or condeming them.

What bothers me most about this whole incident, isn't a debate over what the Toyota tests results actually "mean". It's the fact that evidently Toyota did testing at some level, had results that did manifest into adjustments and change...and that information was not forthcoming or shared with the NHTSA.

If you have nothing to hide? Why are you hiding that information?

CNN may or may NOT be spinning this in a sensational manner. Since I can't read Japanese I don't really know.

 

lol

Why does Toyota test their vehicles if there are no problems? lol.

 

yes.. they tested pre-production product and improved it.
I bet they do millions of these during course of product testing.

Most important part here that this is not even production product and that car didnt even move... they just changed the level of sensitivity of the sensor and speed of reaction of radar sensor, from 0.5s to even less.... car again did not even move, warnings triggered.

Which is irrelavant completely actually. It does not matter. This is preproduction testing.
I am sure they had ACC not even work at all during first tests. Products dont get developed in the limbo, it is trial and error. Which is why tests are being done.

And the product in question was never sold on any market in this form and was never sold on any Toyota/Lexus in USA.

So what is the problem? That Toyota tests their parts before going into production?

Or GM poor sales?

I hope they sue CNN because they have real reason to do so.

 

The "telling" issue was that they added a specific test to yet another, a different model, to be sure it wasn't subject to the same "SUA" flaw. If the they were satisfied that the firmware was fixed for the initial product why not trust that fix for subsequent products...?

 

there is no SUA... it is adaptive cruise control, it is supposed to accelerate on its own. It has nothing to do with SUA.

 

???? That's not something I said. Of course all automotive manufacturers test their vehicles.

The point is? Not all manufacturers are involved in huge NHTSA investigations...and not all manufacturers evidently have documents that seem to contradict statements they made about their own testing in the past.

 

The 'SUA' in their test, and the 'SUA' suffered by many US drivers, don't fit under the same definition of 'SUA'. One phrase is being used to describe different events, and CNN got confused by the shared words.

Have you ever heard of Regression Testing?

Don't trust. Verify. There is damn good historical reason for this.

 

"...That's not likely..."

More likely than otherwise, a LOT more likely than otherwise.

Assuming NipponDenso is the source (more likely than otherwise) for the core software then dozens of marques, even US marques, will be using the same "base" software.

Who do you suppose writes, supplies the base/core source code, or at least specifies the software for all of the third party devices, climate control, transaxles, etc...??
