MSC to Host CDR User Training Classes in December 2012 (CDR Version 8.0 & Newly Covered Vehicles)

Kelly Messerschmidt
Technical Communications Manager
MSC

Messerschmidt Safety Consultants (MSC) will host the CDR Systems Operators Class and the CDR Analysis and Applications Class on December 3 – 7, 2012, at The Accelerator at Southern Miss, which is located in Hattiesburg, Mississippi. The classes will be taught by instructors Brad Muir and Jon Northrup, of Crash Data Specialists LLC. Muir and Northrup will be using the latest version of the Bosch Crash Data Retrieval (CDR) System, version 8.0.

The CDR System allows users to image important vehicle crash data present in the Airbag Control Modules (ACMs) of most late model production vehicles from manufacturers including Chrysler, Fiat, Ford, GM (Chevy, Olds, Buick, Pontiac, Saturn, Cadillac, GMC, Holden, & Opal), Honda/Acura, Isuzu, Mazda, Mitsubishi, Nissan/Infiniti, Saab, Sterling, Suzuki, and Toyota/Lexus/Scion.

Learn more about the vehicle coverage in CDR Software v8.0.

The CDR Systems Operators Class is an eight-hour class that covers the basics of operation, including how to determine if the subject vehicle is supported by CDR, how to select the appropriate connection method to safely image crash data, and how to create reports and save the imaged data for later use. This class serves as the prerequisite for the 32-hour CDR Analysis and Applications Class, which Crash Data Specialists will be teaching Tuesday through Friday (December 4 – 7, 2012).

The CDR Analysis and Applications Class teaches users how to understand the function of the Event Data Recorder (EDR) information present in some ACMs. In this class, users perform line-by-line data analyses, learn how to apply the data to the crash, and receive instruction on delta-v, closing speed analysis, and a variety of additional topics.

Register for the CDR classes online, or register by calling MSC's office at 205.444.0071.

Bruce Gazdick's "Practical Applications of CDR Technology" Class Taught at MSC

Bruce Gazdick's Power Distribution Center (PDC) tool

William Messerschmidt
Principal Technical Analyst
MSC

On June 18th, Messerschmidt Safety Consultants (MSC) hosted "Practical Applications of CDR Technology," at our Pelham, Alabama office. The course was taught by Mr. Bruce Gazdick of L & L Investigations and was attended by the staff of MSC, as well as local law enforcement officers from Hoover and Pelham, AL Police Departments.

It was a great privilege for us at MSC to have Bruce Gazdick teach this fantastic class at our Pelham, AL office. Bruce is a former Jacksonville, Florida Deputy Sheriff who handles products liability investigations nationwide with ESIS and EAA. Bruce also works as an instructor for the Institute of Police Technology and Management, where he teaches "Event Data Recorder Use in Traffic Accident Reconstruction," along with Mr. Richard Ruth and Mr. Bill Wright.

Bruce designed and developed the Power Distribution Center (PDC), which is a tool that facilitates accessing Event Recorder data in heavily damaged passenger vehicles. The eight-hour course, which included lecture, Q&A, and hands-on training focused on using the PDC and preserving diagnostic fault data in airbag modules.

We'd like to thank all of those who attended--and especially our instructor Bruce Gazdick--for an excellent day of training!

US Senate Passes Bill 1813 Mandating Event Data Recorders (EDRs) in Passenger Vehicles by 2015

Benjamin Smith
Principal Technical Analyst
MSC MS

Earlier this month, in the 2nd Session of the 112th congress, the United States Senate passed Bill 1813, which mandates the presence of event data recorders (EDRs) in all vehicles sold in the US by 2015. Additionally, the US House of Representatives is considering similar legislation.

Section 31406, titled “Vehicle Event Data Recorders,” indicates that Part 563 of Title 49, Code of Federal Regulations, will be revised with new regulations centered on the implementation, capabilities, ownership, and accessibility of EDRs in passenger vehicles available in the United States.

Furthermore, Part D (revisions) of Section 31406 requires that EDRs record data for a “reasonable” amount time before, during, and after an airbag deployment or rollover and that these data be accessible by means of “commercially available equipment” in a “specified data format.”

SAE EDR Symposium: Day 2, Session 3

Bill Messerschmidt
Manager
Messerschmidt Safety Consultants

We're into the home stretch of an excellent conference, and the first session after today's lunch is Passenger Car Event Data Recorder (EDR) Applications.

The first speaker is Michael Varat from KEVA Engineering. Mr. Varat is discussing a method of modeling and completing an incomplete crash pulse in passenger vehicle EDR data sets. In this case, the RCM from a Ford captured a portion of the crash pulse, but not the entire pulse. Mr. Varat's presentation uses the techniques for crash pulse modeling, or curve fitting, that are described in his 2000 SAE Technical Paper. This is super cool! Mr. Varat mentioned that the technique he is describing will be the subject of a 2012 SAE paper. I am looking forward to reading it!

The second speaker is Dr. Matthew Craig of NHTSA, who is discussing Advanced Automatic Collision Notification (AACN). The goal is to get the "right person to the right place, at the right time." This means getting those who are seriously injured to a Level 1 Trauma Center. This is extremely important and useful information. Having worked in law enforcement and been a first responder to quite a few crashes, I'm well aware of how difficult it can be for medics and officers to respond appropriately and make good triage decisions. EDR data may be highly beneficial to AACN algorithms. NHTSA is working with the CDC on estimating the benefits of AACN, as well as the implementation of AACN systems to the level of the 911 center.

The third speaker is Tony Reed from TRL in the United Kingdom. Mr. Reed is discussing the EDR experience in the UK. Most EDRs are purpose built Incident Data Recorders and have been used mostly by emergency responders (police, fire, ambulance). Less than 1% of the UK fleet are US vehicles, based on Mr. Reed's research. In spite of the small numbers, TRL has taken a leadership role in EDR data acquisition and analysis in the UK, and has purchased the CDR Tool.

Mr. Reed discussed a case where the Thames Valley Police called on TRL to use the Bosch CDR Tool. (I am jealous by him stating that in the UK, all police agencies use Total Stations and will be moving to 360 degree laser scanners.) The case involves a Chrysler 300 that struck a slow-moving vehicle on the M40, west of London. Mr. Reed was able to cross-check the EDR data using both HVE Software and also with CCTV that was active on the Motorway. Using these techniques, Mr. Reed and TRL were able to validate the EDR, and the striking driver pled guilty to Careless Driving Causing Death, "in the face of overwhelming evidence." Very neat stuff!

Over the last two days, I've had the great pleasure of speaking with Mr. Reed at some length on the subject of electronic tachographs that are mandated by the EU and in use throughout Europe. Seeing the type of data mandated and available in the EU has been very interesting.

The last speaker in this group is Cleve Bare of Exponent, who is discussing the potential issues with Serial Bus latency as pertaining to pre-crash data. Mr. Bare and his colleagues instrumented a test vehicle and demonstrated that the speed shown at Time = -1 occurred at random intervals, evenly distributed at any point in the final second before algorithm-enable. The vehicle speed was accurate to within approximately 1 mile per hour. Their hard braking runs showed wheel slip as would be anticipated in such circumstances.
