What on earth is going on with those Toyotas?
U.S. Transportation Secretary Ray LaHood today announced two investigations designed to answer questions surrounding the issue of unintended vehicle acceleration.
LaHood also asked the U.S. Department of Transportation Inspector General to assess whether the NHTSA Office of Defects Investigation conducted an “adequate review” of complaints of alleged unintended acceleration reported to NHTSA from 2002 to the present.
The ongoing controversy of the problem in Toyota and other vehicles have led to numerous charges from critics that NHTSA is underfunded and improperly staffed to deal with safety matters. It appears particularly weak in the area of electronic controls and systems, as automakers continue to expand rapidly their use in all vehicles.
There are also charges that former NHTSA employees working for Toyota prevented thorough investigations and delayed safety recalls.
The independent National Academy of Sciences will examine the subject of unintended acceleration and electronic vehicle controls across the entire automotive industry. A panel of experts 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 study is expected to take 15 months. See The Case for “Black Box” Electronic Data Recorders
NAS experts will look at software, computer hardware design, electromagnetic compatibility and electromagnetic interference. The panel will make recommendations to NHTSA on how its rulemaking, research and defect investigation activities may help ensure the safety of electronic control systems in motor vehicles.
NASA Specifically on Toyota Issues
Separately, the National Highway Traffic Safety Administration, DOT’s vehicle safety agency, has enlisted NASA engineers with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to help tackle the issue of unintended vehicle acceleration in Toyotas. At least 52 deaths are allegedly the result of the well-publicized problems and an ongoing series of recalls for Lexus and Toyota models. (more…)
