Toyota: pedal fixes are working - debunks expert professor

 Toyota: pedal fixes are working - debunks expert professor
2010 Toyota Electronic Throttle Control, 03 March 2010, Dr. Matthew Schwall of Exponent

Embattled automaker Toyota held a press conference and photo op yesterday to convince the car buying public that their vehicles are safe.  The event was organized to gain credibility following claims by a Southern Illinois University professor that Toyota's sudden acceleration problem is electronic.

Professor David Gilbert of SIU went on record saying that he was able to recreate the sticky gas pedal by adjusting the electronics involved.  Further, Gilbert stated that it was possible for no error code to be created from the problem.

Toyota disagrees with Gilbert's findings, and hired a batallion of experts to prove his theory as unrealistic.  Amongst them was Stanford University researcher Chris Gerdes, who said the SIU experiment is not possible in the real world.

"You cannot rewire a circuit and expect it to behave as it was designed to," Gerdes told reporters.  Gerdes runs Stanford's Center for Automotive Research, and works as an associate professor in mechanical engineering.  He believes advanced electronics in vehicles, like stability control, has led to a reduction in driving-related fatalities.

However, Gerdes did backpedal a bit at the event.  "I don't want to go on the record saying there is not a problem with Toyota," he was quoted as saying. "I have not studied the matter that well."

Toyota used Irvine, California, engineering company Exponent to replicate the SIU experiment on other vehicles, including the BMW 325i, Ford Fusion, andd Subaru Outback.  After the circuitry was changed the way Professor Gilbert outlined, each of the three had similar acceleration problems.

"We don't think there is a ghost issue out there," said electronics general manager Kristen Tabar.  However, Tabar, who works at the Toyota Technical Center in Ann Arbor, Michigan, did say that more work needs to be done, and that all claims need to be examined.

Nearly eight million Toyota vehicles have been recalled in the last few months.

Ok so this guy is a doctor. And he thinks that it is surprising that with a computer unit meant to program and scan all the sensors in a car he can alter the way the car functions. That's like saying on a computer, "hey there is still a problem with all hardware, if you uninstall your drivers your piece of hardware wont function" GENIUS!!

...except for the news today, March 8, 2010 that another Toyota Prius in southern California, USA exhibited run-away acceleration of 94 mph. The Police helped to bring the Prius to a safe stop with no one hurt...they interviewed the driver and you could plainly see he was scared out of his wits...

Just to highlight that it was an automatic acceleration that made th car reach 94mph, not a stuck pedal! If that's not electronics, then what is it? Toyota is so terrified that it could be electornics that they make massive press conferences and try to prove otherwise! But are they willing to tackle the problem or are they too scared that if indeed it is an electronics problem, they would have to recall ALL TOYOTA'S AND LEXUS CARS and they currently don't even know what the problems are. Why have they not recalled the Lexus models? accidents have happened, causing deaths due to this acceleration problem in Lexus cars!!! Further poving that it is not just a pedal problem in the Toyota's. One thing for sure - I AM NEVER GOING TO DRIVE OR BE A PASSENGER IN A TOYOTA OR LEXUS. I urge all Toyota and L drivers to stay away from highways and keep your following distances... I don't want some Toyota hitting me from behind!

I had the same problem with my Jeep in the 70's. I would just turn off the engine or place the engine in neutral or put the brakes on really hard as it was fairly easy to overcome a fairly underpowered engine with the brakes. Jeep could never find the problem so I sold it. I guess all cars would benefit from throttle deactivation with application of the brakes.

I guess with all this new technology there will probably be more problems.. How is Chevy dealing with the Cobalt electric steering problem?

No more excuses for breaking the speed limit, then?

lol Toyota entirely ignored/didn't understand what the professor was trying to explain. By forcing the system to go into the sudden acceleration scenario/glitch, there wasn't any warnings displayed on the ecu. No warnings is what Toyota has up until now lazily relied on to say their ecu is fine.

Why would their be? There is no recording of such things on ANY car, the accelerator being fully pressed is not flagged as an error. I don't know about what car you drive, but if the check engine light comes on when the gas is fully pressed there is a problem....

No problem eh? Funny that there has been at least 60 reported sudden acceleration incidents on Toyota vehicles that had their gas pedals / floormats replaced, and as somebody already said a 2008 Prius just did the same thing yesterday. A Tundra owner in British Columbia ended up in a ditch because he could not stop his truck and when he asked Toyota to investigate the electronic data recorder they refused. There is either an endless loop in the software that occurs in certain conditions, or the computer chip has a flaw.

This is a blessing in disguise... Toyota, you better double check your cars...before you put them on the road again. One more thing, please try to make more attractive cars in the future...

Back to my original thoughts, why was that person pushing the pedal all the way down...Especially now knowing that there is a problem. Why hasn't he taken in his car in for the recall? Why didn't he put it in Neutral, pull over, pull the hand brake and shut off the engine...Retards look for an excuse/lawsuit. I mean i can kill myself in any car with a manufacturer problem/lack of warning. I could swallow the push cigarette lighter, and blame them for making it small enough to swallow and not put a warning on it saying "don't swallow".

calm down people, the whole Toyota-circus is so obvious, that make me think, it's a "stun" by Govt. Motor team up with media & government... everything "planned" at the right time. just think, people... it's start getting annoying now. if i were the CEO of Toyota, i would say: ok, let's shut down all U.S. factories, lay-off all employees, stop purchase parts from all U.S. suppliers... we're doing fine in homeland, Europe & Asia. & China is soon to be the biggest market anyway, let's start over ther... forget the U.S. Market, let those people deal with their G.M. junk!

I find it interesting that NHTSA all of a sudden has a conscience now that it comes to a problem with a Japanese automaker. They covered up problems with 4WD rollovers for decades and am pretty sure that these rollovers account for many, many more fatalities in the US. Their agenda was simple - to save Detroit. I'm not saying that SUA in Toyotas should not be investigated. It should. But it makes you wonder if NHTSA's agenda has changed very much, if at all, over the last few decades.
