Toyota Sudden Acceleration Is Driver Error
phantomfive writes "The NHTSA has investigated data recorders from Toyota cars whose owners claimed to have crashed due to an accelerator error. They found that the throttles were wide open and the brakes weren't being pressed. The investigation looked at a sample of the cars, selected by the NHTSA." Jamie found this article with a superior headline at Balloon Juice.
... that the throttle and brake position logging was recording correct data. If there's a fault in the ECU or software, how can you guarantee the data logging is correct?
I am not surprised.... Same thing happened to Audi back in the day.
One thing for me that was a dead giveaway was that every single report regarding the Toyota sudden acceleration issue happened in the good old United States (Same for Audi, by the way). Statistically, it's very unlikely that such a problem would only happen in a single country even though these cars do not differ significantly between different countries. You'd expect a few deaths in Japan, France, German, the United Kingdom where Toyota cars are also very popular.
Too bad for Toyota that their brand has been permanently damaged in the US. (Just ask Audi how well it went for them the years after the accusations). GM, Ford and Chrysler are probably very happy about this.
While this is a useful data point, it's not conclusive. If the root cause is some electronics error whose symptoms are a sudden acceleration and (according to two victims) no response to the brake, it's not surprising that the black box -- presumably using the exact same input controlling the engine -- would claim that the accelerator was fully pressed and the brake was untouched.
Driver error... Great! So all Toyota needs to do is issue new drivers.

From the article: Police in Sheboygan Falls, Wis., investigated and believe driver error was to blame, Chief Steven Riffel said Tuesday. He said surveillance video showed that the brake lights didn't illuminate until after the crash. But Mr. Riffel said that determination is preliminary and that his agency has turned over the investigation to NHTSA. Based on the black box data, NHTSA investigators found that the brake was not engaged and the throttle was wide open, according to a person familiar with the matter. Ms. Marseille sticks by her story. "It makes me very angry when someone tells me, 'She probably hit the gas pedal instead,' because I think it's a sexist comment, an ageist comment," she said.
Brake lights are controlled by a simple switch in the brake assembly. Regardless of how much TOyota may have jacked up the throttle system I doubt they were able to screw that up too. Sounds like most these idiots are too stupid to own a car

Notice that all the problems happened at around the same time. It's not a constant failure rate.
The problem caused a massive amount of publicity and public awareness. Toyota drivers would most likely see problems where before they'd just shrug and carry on. I bet you'd see a similar effect for any manufacturer if you could create a suitable media storm.
No sig today...
I am not surprised with this outcome. I read an article from Car & Driver a while back where the specifically tested the scenario of trying to stop your car with the throttle wide open. Here's the link.
br> Key facts:
1) In a Toyota, shifting into neutral while the throttle is wide open, will disengage the engine from the transmission and slow the car down. So all of the people claiming that these cars are all computers and not mechanical so it still wouldn't work, are full of crap.
2) They brought a standard Toyota Camry up to highway speed (including a 100 MPH test) and hit the brakes while still holding down the accelerator. The result? The brakes were able to overpower the engine and slow down the car. The faster your initial speed, the longer it took, but the distances, even at 100 MPH, were reasonably safe.
C/D's conclusion without actually analyzing the specific reported incidents, was that the most likely cause of these accidents was driver error, specifically people hitting the gas instead of the brake. The natural instinct for any driver if a car starts accelerating uncontrollably is to hit the brakes, which C/D has shown is sufficient to slow the car on its own. If that wasn't sufficient, then the thing to do is to shift into neutral. This real data from the incidents seems to support the gas instead of brake theory, and the statistics showing a sharp spike (and subsequent sharp drop-off) in "unintended acceleration" incidents after Toyota instated the recall for sticky accelerators and at a time when the US auto industry has one foot in the grave, Toyota is looking more and more in the clear on this one.

Here's a list (SUA) sudden unintended acceleration complaints to the NHTSA

Atop that, most of SUA complaints to the NHTSA are a sham.

Its not about a design flaw, some people are on their cell phone, distracted, and in some cases plain DRUNK. One Toyota SUA had a driver with a blood alcohol level of .103 (link above). Its easier to blame the car rather then admit you were drinking or were texting on the cellphone.
In other cases it turned out to be a complete hoax (in the case of the California Prius incident):

The 2009 Lexus ES 350 that California Highway Patrol Officer Mark Saylor was driving was a "loaner" vehicle given to him temporarily while his car was being repaired.
It has a "starter button" instead of an ignition key, and requires that the bnutton be depressed for 3 or more seconds if the car is in gear, or it may not function to turn the car off at all over certain velocities.
The shifter has a strange configuration which allows it to "emulate" a manual transmission while it is really an automatic transmission. The "N" position is also used to shift up a gear.
