Messerschmidt and Austin to Present at the 2012 ARC-CSI Crash Conference

Bill Messerschmidt of MSC, and Tim Austin of the Wisconsin State Patrol Academy will give a presentation on “Using ECM Diagnostic Data in Crash Reconstruction” at the 2012 ARC-CSI Crash Conference, which will take place June 4-7, in Las Vegas, Nevada.

Messerschmidt and Austin’s presentation explores the presence of important, volatile fault data in heavy vehicle Engine Control Modules (ECMs) that are oftentimes ignored, inadvertently erased, or overwritten during the ECM data imaging process.

They will discuss how and when diagnostic records are written, how they can be useful in collision investigations, as well as how the data can be preserved correctly. Messerschmidt and Austin will describe data imaging methods, such as the use of surrogate vehicles and devices like the “Truck in a Box.”

The ARC-CSI Crash Conference takes place annually and—as they have done for the past 10 years—the ARC-CSI Crash Team will conduct multiple, fully instrumented live crash tests of vehicles in real world crash scenarios. Learn more about the crash tests.

The two days that follow crash test day are comprised of technical presentations given by experts from around the world on topics relevant to investigating and reconstructing vehicle collisions. Learn more about the topics and speakers for the 2012 ARC-CSI Crash Conference.

Bendix ABS Research by Ben Smith Forthcoming at SAE 2012 World Congress

Messerschmidt Safety Consultants (MSC) is proud to announce that Benjamin Smith, in conjunction with Timothy Austin of the Wisconsin State Patrol and Mike Farrell of Fox Valley Technical College, will have their most recent research published at the upcoming Society of Automotive Engineers (SAE) 2012 World Congress in Detroit, Michigan, April 24-26.

Their technical paper, “An Examination of Diagnostic Event Data in Bendix Antilock Brake System Electronic Control Units,” will be presented during the Event Data Recorders (EDR) section of the Occupant Protection session.

The paper pertains to the function and accuracy of the Bendix EC-60 and EC-30 ABS controllers in real-world crash scenarios. In particular, the study focuses on the diagnostic event recording and reporting functions within the electronic controllers of Bendix ABS systems.

This research is unique, as it is the first time that Bendix ABS systems have been formally explored as a source of crash event data in the investigations of motor vehicle crashes. The underlying research for this paper was conducted in the spring of last year on late-model Volvo and International commercial vehicles in Appleton, Wisconsin.

SAE EDR Symposium: Day 2, Session 5

The final session of the SAE 2011 Highway Vehicle Event Data Recorder (EDR) Symposium - a fine event - was the second Unique Applications.

The first speaker was Dave Plant from Washington, D.C. Mr. Plant spoke about research with the new DDEC 10 ECM system. Impressively, he was able to not only describe the new attributes of the DDEC 10, but he also compared this new system to the results of both SAE 2010-01-1004, which he co-authored (dealing with power loss and key signal requirements) and SAE 2001-01-0808, which dealt with data retrieval methods in other Detroit Diesel engines (and which Dave was the lead author of). Most interestingly, the DDEC 10 is a three-module system, with an additional module that controls emissions.

The second speaker was John Brophy from NHTSA. Mr. Brophy discussed the NHTSA NASS, SCI, and CIREN programs. These projects are currently collecting data, including EDR data, on thousands of crashes each year to be used in various highway safety projects (such as Dr. Gabler's work, which was discussed on Day 1). For example, between 2007-2009, NASS and SCI conducted 21,000 vehicle inspections, collecting approximately 600 data points per crash.

The third speaker was yours truly, discussing driver braking behavior in heavy vehicle (HV) crashes. My research attempts to use HVEDR data for the purpose of determining the characteristics of HV operator braking responses in crash and near-miss events. The research was able to demonstrate similar braking behavior between the HV operators and research respondents in testing of passenger vehicle drivers.

The final speaker was Balaji Yelchuru, who discussed using EOBR and on-vehicle technologies for green transportation. There seems to be a great deal that electronic real-time data can do, not just for our immediate safety as road users, but also for our environmental health and well being.

Well, that's a wrap. I hope those who followed my live-blogging found it enjoyable, and I hope to see you at future SAE events!!!
