u.s. auto safety agency nhtsa needs improvement - study says  -  car electronics system
Focus on US: critics point out that electronics may be the reason for Toyota's unexpected acceleration, but a report from NHTSA and NASA last year pointed out other problems. NEW YORK (CNNMoney)--
According to a new report from the National Academy of Sciences, government safety regulators and NASA researchers believe that the electronic problem may be the cause of the unexpected acceleration of Toyota's car, which is correct.
However, the National Highway Traffic Safety Administration should have the expertise to reach this conclusion without the need for outside help.
NHTSA feels incapable of investigating Toyota (TM)
The NAS reported that the electronics themselves showed the agency's disturbing weaknesses.
The technical expert group writing the new report was convened by the NAS at the request of the National Highway Traffic Safety Administration to study how to use computer control systems to investigate the future of unexpected acceleration of modern cars.
After the establishment of the NAS committee, NHTSA released a report last year, and there is no reason to believe that the failure of software or electronic systems is related to a large number of reports that Toyota Motor accelerated out of control.
As some consumer rights advocates and personal injury lawyers claim, NHTSA has recruited scientists from NASA to investigate the possibility of faulty electronic devices.
Instead, the report found three possible reasons: the floor
The cushion of the accelerator pedal.
Throttle pedal defects that cause some accelerators to get stuck.
And, in many cases, the driver mistakenly pressed the throttle instead of the brake pedal.
Toyota recalled millions of vehicles in 2008 and 2009 related to pedals and ground pad obstacles.
Although the new NAS report supports NASA's conclusion and believes that the NHTSA's decision to close the investigation is "reasonable", it does send a red flag.
The report said: "It is disturbing that concerns related to unexpected acceleration have evolved into questions about electronic security that NHTSA cannot convincingly answer, which requires NASA to provide extensive technical assistance.
In contrast, automakers are now developing or even opening more complex and complex electronic systems to the public ---
Including the technology to drive your own car. -
Electronic throttle control is relatively simple and clear.
The NAS reports that given that the technology is almost ubiquitous in modern cars, NHTSA should have the technical expertise to handle the survey itself.
"NHTSA has taken steps to strengthen its expertise in electronic control systems while expanding research in this area ---
The agency has extensive experience in research, rulemaking and law enforcement projects dealing with automotive electronics issues, "the security agency said in a statement in response to the NAS report.
The NAS reports that increasingly complex electronic systems will only increase the likelihood of security issues.
The report therefore urges NHTSA to conduct a strategic review to enhance the security agency's technical expertise in automotive computer systems.
Like the Federal Aviation Administration, which is responsible for aircraft safety, NHTSA should be more involved ---
And earlier. -
Automakers are looking for ways to ensure safety.
Among other specific proposals, the report said that NHTSA should convene a "permanent technical advisory group" to address electronic issues.
The report also strongly supports NHTSA's requirement to improve the "event data logger" so that they can track a wider range of data.
Today's equipment installed on most new cars keeps recording data-
Includes the use of speed, throttle and brake pedal, and steering wheel angle--
Then store the data for a few seconds in the event of a crash.
Improved data recorders can look for short electronic faults and driver errors, making it easier to diagnose system defects, the report said.
