NASA Can't Find Unintended Acceleration Causes in Toyota's Electronic Throttle Control System Page 3



National Academy of Science panel which is also investigating possible links between UA and electronic vehicle controls across the entire automotive industry will report its findings later in the year.

Shares in Toyota jumped about 5 percent on the NASA report, according to the BBC.

Toyota's response to the report's findings was this:

"Toyota welcomes the findings of NASA and NHTSA regarding our Electronic Throttle Control System with intelligence (ETCS-i) and we appreciate the thoroughness of their review. We believe this rigorous scientific analysis by some of America's foremost engineers should further reinforce confidence in the safety of Toyota and Lexus vehicles. We hope this important study will help put to rest unsupported speculation about Toyota's ETCS-i, which is well-designed and well-tested to ensure that a real world, un-commanded acceleration of the vehicle cannot occur."

Even with the release of NASA's report, the debate over whether electronics play a role in UA in Toyota vehicles will continue for some time to come, at least in court. One of the lawyers involved in a UA class action lawsuit against Toyota is quoted in this Daily Breeze story as saying that the NESC team didn't "account for the fact that we continue to see runaway events post-recall. People have had their cars fixed - the pedals and mats - and NHTSA is still getting complaints."

"I don't think the report ends this matter one bit," the lawyer was quoted as saying.

This story, written by Robert Charette, was originally posted on IEEE Spectrum, an editorial partner of High Gear Media.

  1. The NASA study is hard to swallow in light of the many credible people who have had the problem. Is it possible that the electronics function fine in a test environment, but are affected by the presence/certain type or proximity of cell phones in the user environment. Has anybody ever examined whether a certain type of cell phone, computer, or mapping system was common to all these incidents?
    As in avionics, even though frequency interruption is rare, there must be some degree of a risk, so they ask everybody to turn off their electronic devices during takeoff and landing.
    Hard to believe that the best and brightest would not have already examined or discarded this theory by now. Just wondering.
