Electromagnetic signals' link to gas pedals probed
The National Highway Traffic Safety Administration is investigating whether#x electromagnetic signals such as Compact fluorescent lampthose from radar and cellphones could interfere with electronic gas-pedal controls in vehicles including Toyotas.
Transportation Secretary Ray LaHood confirmed Wednesday that the government is investigating potential electrical problems. LaHood said NHTSA will conduct an investigation into electronic throttle control systems and potential electromagnetic interference in the nation's fleet of vehicles.
The agency plans to meet with Toyota and other manufacturers, suppliers and outside experts to better understand the electronics that control engine throttles and the safeguards to prevent problems when vehicles are exposed to "electromagnetic interference," or EMI.
Some plaintiffs' attorneys and consumer advocates say signals from radar, radio waves and other sources are causing vehicles' electronic throttles to accelerate on their own.
NHTSA plans to do more vehicle testing for EMI if interviews Compact fluorescent lampwith auto industry officials and experts suggest it's necessary, said one official, who was not authorized to comment publicly.
Federal safety officials also have widened their investigation of Toyota's sticky gas pedals to see if the same problem could exist for other automakers using CTS parts.
NHTSA has sent a letter to CTS, the Indiana company that made the pedals behind Toyota's recall of millions of vehicles,google优化, to find out more about gas pedals CTS made for other companies.
CTS says it makes pedals for Honda, Nissan and a small number of Ford vehicles in China.
NHTSA's Office of Defects Investigations on Tuesday #xinterviewed United Kingdom-based electromagnetic interference expert Keith Armstrong, who says EMI is a "likely cause" of some of the unintended acceleration in Toyota vehicles. Armstrong will testify as Compact fluorescent lampan expert witness in a Ford sudden-acceleration lawsuit in Florida this week.
