Exponent’s Event Data Recorder report is based on extensive testing of a cross-section of Toyota and Lexus models. These include models that had the highest rates of Vehicle Speed Control complaints made to the NHTSA. Exponent’s report validates that Toyota’s Event Data Recorders (EDR) are a highly reliable and useful tool that, along with physical evidence and forensic analysis, can help investigators reconstruct and understand the causes of a collision.
Exponent’s report on Toyota’s EDR is the first of several sections of a comprehensive, independent investigation Exponent is undertaking on issues related to claims of unintended acceleration in Toyota and Lexus vehicles. Retained in 2009, Exponent is conducting tests of various aspects of Toyota’s Electronic Throttle Control System with Intelligence (“ETCS-i”) in multiple vehicles under a variety of normal and abnormal conditions. As each of the remaining installments of the overall report are completed and provided to Toyota in the coming months, Toyota will make them available for public review as well.
Last year, as part of its overall commitment to strengthen quality assurance in North America, Toyota committed to increasing the availability of Toyota’s EDR read-out tools, and today there are more than 150 Toyota EDR readers deployed across North America and the U.S. territories. Fourteen of these devices were delivered to the NHTSA and Transport Canada to allow these regulatory agencies to retrieve data independently from Toyota vehicles during their investigations.
Moreover, Toyota and Bosch have entered into a license agreement to allow commercially available Bosch Crash Data Retrieval Tools to have access to Toyota EDR system information. All of Toyota's 2011 model year vehicles are equipped with advanced EDRs that have the ability to capture pre-crash as well as post-crash data.
Comprised of graduates from the most highly regarded engineering programs in the world, such as Cal Tech, Stanford, and MIT, Exponent is one of the world’s foremost engineering firms, having provided consulting services to the automobile industry for 40 years. Exponent scientists and engineers also are called on to present their opinions in judicial proceedings, and to do so for Toyota in cases involving unintended acceleration. Exponent has conducted several major engineering and scientific investigations for the U.S. government.
Exponent was retained by the NASA in 1986 following the Challenger explosion to evaluate the safety of the shuttle design components. Exponent was also called in to determine how to safely conduct the rescue effort after the Oklahoma City bombing, and its engineers were on FEMA's Search and Rescue Teams following the September 11, 2001 terrorist attacks and Hurricane Katrina. Exponent is currently working with the U.S. Army to improve the military’s Improvised Explosive Device detection technologies to help protect our soldiers in Afghanistan and Iraq.
