WASHINGTON — NASA and the National Academy of Sciences are joining the government’s effort to figure out what caused the sudden acceleration problems that led to Toyota’s massive recalls.

NASA scientists with expertise in electronics will help the National Highway Traffic Safety Administration study potential electronic ties to unintended acceleration in Toyotas. NASA’s knowledge of electronics, computer hardware and software and hazard analysis will ensure a comprehensive review, Transportation Secretary Ray LaHood said Monday.

In a separate study, the National Academy of Sciences will examine unwanted acceleration and electronic vehicle controls in cars from around the auto industry, LaHood said. The National Academy is an independent organization chartered by Congress.

These studies taking about 15 months will cost about $3 million, including the expense of buying cars that have allegedly had unintended acceleration. Both studies will be peer reviewed by scientific experts, the Transportation Department said.

Toyota said in a statement it was “confident in our vehicles and in our electronics” and would cooperate with the government review.

“These studies are just the kind of science-based examination we have been calling for. Bringing some sunshine to this subject is bound to separate fact from fiction, which will be good for Toyota, the industry and the motoring public,” the company said.

“Carmakers have entered the electronics era, but NHTSA seems stuck in a mechanical mindset,” House Energy and Commerce Committee Chairman Henry Waxman, D-Calif., said last month. “We need to make sure the federal safety agency has the tools and resources it needs to ensure the safety of the electronic controls and on-board computers that run today’s automobiles.”

Toyota has attributed the problem to sticking gas pedals and accelerators that can become jammed in floor mats, and has cited no evidence of an electrical problem. The company has noted that other manufacturers also have had reports of cars surging forward.

Reviews of some recent high-profile crashes have failed to find a mechanical or electronic problem…

A police investigation of a March 9 accident in suburban New York involving a 2005 Prius found that the driver, not the car, was to blame. Tests following a March 8 incident in San Diego in which a driver reported the gas pedal on his 2008 Prius got stuck, leading to a 94 mph ride on a freeway, found that the hybrid’s gas pedal, backup safety system and electronics were working fine. NHTSA’s review of Toyota’s electronic throttle control systems is expected to be completed by late summer. The safety agency, with NASA’s help, is looking at electronic systems used in Toyotas and whether they have flaws that would warrant a defect investigation.

The National Academy of Sciences’ National Research Council will review industry and government efforts to identify possible sources of unintended acceleration, including electronic vehicle controls, human error, mechanical failure and interference with accelerator systems.

The experts will look at software, computer hardware design, electromagnetic compatibility and electromagnetic interference. They will make recommendations to NHTSA in mid-2011 on how the government agency’s rulemaking, research and defect investigations could help ensure the safety of vehicle electronic control systems.
