Sudden Acceleration, Spaghetti Software and Trauma at the Kitchen Sink

The TOYOTA pictured below belonged to Noriko Uno who spent the last minutes of her life attempting to STOP her runaway TOYOTA.

Many of the victims of TOYOTA have touched my life with the terror they endured in the last few minutes of their lives.

Below is an excerpt from an article, another MUST READ AND SAVE.

Under the right circumstances, this might be any one of us!

[emphasis added]

.....It wasn’t until the Booker v. Toyota
case was heard in an Oklahoma court in October 2013 that
malfunctioning electronics became the central issue.
In September 2007 75 year old Jean Bookout had been
exiting an Oklahoma highway in her 2005 Toyota Camry
when it suddenly accelerated. Bookout was unable to stop
the car and it fell into a culvert injuring her and killing her
passenger and best friend Barbara Schwarz. Before she
died, Schwarz called her husband and said ‘Jean couldn’t get
her car stopped. The car ran away with us. There`s something
wrong with the car.’ Without this vital information, Toyota’s
various explanations in terms of an elderly driver
mistakenly pressing the accelerator pedal instead of the

brake, a loose all-weather floormat entrapping the
accelerator pedal, or a sticky accelerator pedal might have
sounded plausible to a jury. However, the lawyers engaged
on behalf of Schwartz and Bookout started to investigate
the possibility that the root cause might lie in
malfunctioning throttle control electronics. And here is
where the MDL expert evidence became of critical
importance.

On the hardware front, Professor Todd Hubing and his
team at Clemson University had managed to induce
sudden acceleration incidents by means of EMI without
triggering any fault codes, something that Toyota had
claimed could not happen. On the software front, Dr
Michael Barr, a world expert in embedded computer
systems, was able to provide a very thorough critique of
the electronic throttle control software after having been
given permission to carry out a lengthy examination of the
Toyota Source Code in a locked room under the very
tightest of security conditions. His 800 page report used in
the Bookout case is still under lock and key, but his set of
slides presented to the jury and his testimony are available
on the internet and are well worth reading.4

Barr writes: ‘In a nutshell, the team led by Barr Group
found what the NASA team sought but couldn’t find: “a
systematic software malfunction in the Main CPU that opens the
throttle without operator action and continues to properly control
fuel injection and ignition” that is not reliably detected by any
fail-safe. “’. In other words if there was an electronic
malfunction it would not be reliably detected – and instead
of triggering the vehicle into limp home mode it would
open the throttle and cause a sudden acceleration and no
trace of the fault would be detectable afterwards.


In the footnotes:

It is salutary to remember that every escalator on the
London Underground is fitted with emergency stop
buttons: not so cars fitted with electronic throttles!
