Maybe it's not PEDAL CONFUSION after all



When Bret Quinlan's TOYOTA CAMRY surged out of control, he struck a building.





This is an excerpt of the press release from Mr. Quinlan's attorney: 

However, in March 2014, Toyota entered into a deferred prosecution agreement with the United States Department of Justice in which the company admitted that it mislead consumers by concealing and making deceptive statements about safety issues affecting its vehicles that caused types of unintended acceleration. Toyota subsequently agreed to pay a $1.2 billion financial penalty – to date the largest imposed on a motor vehicle manufacturer. Also, recently many damaging Toyota documents have come to light during the course of unintended acceleration jury trials that have cast a dark shadow on Toyota’s actions in terms of what they knew, when they knew, and issues of ETCS defects.

Additionally, after removing the unintended acceleration allegation from his complaint, Quinlan received notice that the Camry was included in a class action lawsuit against Toyota based on the ETCS defect. Further discovery found Toyota had received more than 37,900 complaints concerning the ETCS, which have been installed in Toyota-brand vehicles sold in the United States since 1998.


FROM: 

+ 37,900 complaints ignored by Toyota




Maybe it's not PEDAL CONFUSION after all.

HOPKINTON – A West Main Street shopping plaza sustained minor damage after a Framingham man drove his car into it on Tuesday.

The driver of the Toyota was not identified as he and a passenger were taken to the MetroWest Medical Center in Framingham after the 12:37 p.m. crash for evaluation, Hopkinton Police Officer Patrick O’Brien said.

The cause of the crash is still not known.

“A person pulled into a parking spot at 77 West Main St., and the vehicle jumped the curb and came to rest against the building,” O’Brien said.

The address is a small shopping plaza that contains several businesses, including Dynasty Chinese Restaurant and Tri-County Medical Associates.

The town’s building inspector looked at the building after the crash and determined there was no structural damage. O’Brien said there appeared to be minor damage to some bricks.

O’Brien said the driver has not been cited, and police hope to interview him and the passenger later after they are released from the hospital.

Toyota and Lexus are #1 in cases of sudden unintended acceleration and FORD is #2. The current unintended acceleration plaguing newer vehicles is the electronically-induced type. The engine throttle control systems depend on computer software to command them. Sometimes glitches occur...like in some of your other electronic devices...which can cause the command to be different than what you desire. The evidence of the glitch is often undetectable after the vehicle is restarted.

Unfortunately, the EDR (black box) is not always accurate as shown by expert Dr. Antony Anderson in his analysis of a 2012 Toyota Highlander. The EDR results indicated the driver was not braking when she was doing so. The EDR results are inconsistent.

The key to avoiding a horrific crash during a SUA event is whether or not the vehicle has an effective fail-safe in the event a glitch occurs. If it does not, as in the case of the glitch-prone Toyota ETCS-i, then the vehicle may become a runaway with an ineffective means to stop it. Unfortunately, the safety standards aren't as strict in automobiles as they are in airplanes. Some manufacturers have more effective fail-safes than others. In the case of Toyota, an embedded software expert, Michael Barr (see Oklahoma Bookout vs. Toyota court case involving a 2005 Camry) found that an electronic glitch could induce a SUA event. Another expert, Dr. Henning Leidecker, found that a SUA event could also be triggered by "tin whisker" formation, particularly in 2002-2006 Toyota Camry vehicles.

SUA events have been DEADLY for vehicle occupants as well as pedestrians and people in storefronts, buildings, and even homes. The numbers of such crashes are ever-increasing with the advent of the very complex ELECTRONIC throttle control systems.

A Case Study of Toyota Unintended Acceleration and Software Safety




ECE Seminar: A Case Study of Toyota Unintended Acceleration and Software Safety



Starts at: September 18, 2014 4:30 PM
Ends at: 6:00 PM
Location: Scaife Hall 125
Speaker: Phil Koopman
Affiliation: Electrical & Computer Engineering, Carnegie Mellon University
Refreshments provided: Yes

Details:Abstract:
Investigations into potential causes of Unintended Acceleration (UA) for Toyota vehicles have made news several times in the past few years. Some blame has been placed on floor mats and sticky throttle pedals. But, a jury trial verdict was based on expert opinions that defects in Toyota's Electronic Throttle Control System (ETCS) software and safety architecture caused a fatal mishap.

This talk will outline key events in the still-ongoing Toyota UA litigation process, and pull together the technical issues that were discovered by NASA and other experts. The results paint a picture that should inform future designers of safety critical software in automobiles and other systems.

Prof. Philip Koopman has served as a Plaintiff expert witness on numerous cases in Toyota Unintended Acceleration litigation, and testified in the 2013 Bookout trial. Dr. Koopman is a member of the ECE faculty at Carnegie Mellon University, where he has worked in the broad areas of wearable computers, software robustness, embedded networking, dependable embedded computer systems, and autonomous vehicle safety.

Previously, he was a submarine officer in the US Navy, an embedded CPU architect for Harris Semiconductor, and an embedded system researcher at United Technologies. He is a senior member of IEEE, senior member of the ACM, and a member of IFIP WG 10.4 on Dependable Computing and Fault Tolerance.
