It does the opposite. the unsecured mat slides forward and when the pedal is pressed forward the mat edge slides on top of the lower edge of the pedal trapping the pedal all the way forward. to expect someone unfamiliar with the car to figure out how to unlock it at elevated speeds in traffic when the pedal has it held in place is pretty unlikely, also. in my vehicles, i might be able to jam the gas pedal from underneath it with a paver sized brick, but not a floor mat. it was also speculated earlier that mat interfered with the braking, but the mat shows no evidence of any contact with the brakes pedal. it's probably like the game mousetrap. the floor mat installation was the trigger in an unlikely sequence of events. i still would like to know that sequence of events was and how repeatable it is. What you're missing here is that the mat that was in the vehicle was not supposed to be there at all. It was an All Weather mat from a different vehicle and it was stacked on top of the OEM carpetted mat and it was not secured in place to avoid it from sliding forward and the dealers have been specifically warned by Toyota and the NHTSA not to stack mats in this manner. It was a cluster from jump street. \) [.... All Weather Mat blocking the Gas Pedal...] .......{....carpetted OEM mat........................................} If the very thick All Weather mats are not in the vehicle to trap the gas pedal then this tragedy doesn't occur. None of the OEM carpetted mats are thick enough to come anywhere near the gas pedal. In addition none are heavy enough to hold the gas pedal all the way in the forward position. In addition they are secured to the floor by two hooks so that they are nowhere near the gas pedal. How do I know? I've tried to cause such a situation on a wide variety of vehicles using only the OEM carpetted mats.

Replying to: kdhspyder (Nov 04, 2009 4:34 pm) you really have no clue how brake assist works, you just think you do. i have no clue how it actually works either, but i am now willing say it can't be tricked. the black box is the best hope to determine what was going on

Replying to: explorerx4 (Nov 04, 2009 7:46 pm) Normal pressure on the pedal in normal situations equals a normal pressure on the brakes. Slamming pressure on the pedal activates the BA function via the ABS system to give you full force right away. If a driver doesn't slam the pedal right away then he/she doesn't get the full stopping force of the BA function. And yes BA probably did not get the right signal in this case as I noted because the driver probably ( my own guess ) thought initially that nothing was really wrong and thus didn't slam on the brakes initially. But this is all speculation and serves no purpose without specific data.

"Toyota Motor Corp. released misleading information about an investigation into problems with stuck gas pedals that led to a massive Toyota recall, the U.S. government said Wednesday, stressing the issue is still under review by federal safety regulators. The National Highway Traffic Safety Administration said it was still investigating the case and meeting with Toyota to hear about the company's plan to redesign the vehicles and fix "this very dangerous problem."

Replying to: kdhspyder (Nov 04, 2009 8:19 pm) don't forget CR had almost no braking from 80 mph will maintaining throttle after doing the same test at 60 mph. i am not willing to make assumptions about what should work based on what happens in normal situations. systems can have unexpected reactions under stress. |
