This four day (32 hour) course will provide the Collision Reconstructionist who has completed a CDR System Operators or equivalent CDR “technician” class the necessary background to understand the function of the Event Data Recorder information present in some electronic control modules on most late model production vehicles available from, but not limited to, BMW, Chrysler, Ford, General Motors (including Holden for Australia), Honda, Mazda, Nissan, Suzuki, Toyota and Volvo vehicles. Note that new coverage will continue to be added in 2013 from other car makers and the data from their systems will be added to class materials as soon as it becomes available. Airbag system deployment decision making will be discussed as it relates to the information recorded within the airbag control modules (ACM) of the CDR system supported vehicles.
Each generation of modules for the supported vehicle families will be covered including line by line analysis of most parameters utilizing CDR reports from actual crashes and staged crash tests where relevant. The students will be provided copies of CDR reports used in the class for later reference.
In addition to the analysis of the individual line items, the application of the data to the crash at hand will be discussed including: delta-v and closing speed analysis, principle direction of force (PDOF) calculation and applications, comparison of pre-crash parameters including vehicle speed, throttle position, engine speed and brake application, methods of comparing internally recorded information as well as information from external sources and how they handshake for comparison, using CDR data in a situational appropriate reconstruction will be covered. Several case examples will be used in assignments to be completed by the attendee's as part of the class material All notes for case examples are made "live" using a Tablet PC and all instructor notes / math are provided in PDF on FUSB flash drive before end of class.
Several Greg Russell Excel programs are also distributed as part of class materials.
*********Crash Data Specialists has gone PAPERLESS! ************** We now distribute a USB "flash drive" at the start of class as well as pads for note taking. ALL class slides are in SINGLE slide to a page with room for electronic notes to be made on the page. All slide material can be Highlighted in the PDF (for classes after June 2014). All notes made are SEARCHABLE from within the PDF eliminating the need for "stickies" and highlighters on paper!. Adobe Acrobat 11 or newer REQUIRED. Acrobat is a FREE program downloadable from Adobe.com. Both PC and MAC versions are on the USB flash drive. NOTE: CDS maintains a small number of "NetBooks" that will be available at class. Please ADVISE upon registering if you will require hard-copy and a link to a printable version will be provided for download and local printing.
Individual course sections include:
- Terms and Conventions found in relation to CDR/EDR field
- Airbag deployment decision-making basics - how, why and when airbags and related system deploy
- Crash Sensing and critical timelines - idealized timeline for decision making, other inputs to the systems
- Crash Pulse recording methodologies currently used i.e. g vs. time or delta-v or when both may be recorded
- Delta-V recording variations - which systems record x-axis only, whoch record x and y axis and for what time period data is recorded
- Calculating Principle Direction of Force from CDR data - what you need to know and be aware of
- The NHTSA CFR 49 Part 563 Rule is discussed with examples of Part 563 intent ACM data is presented
- Pre-crash data sources and things that can affect their accuracy
- BMW vehicles supported and the data from their ACM (known as an ACSM - Advanced Crash Sensing Module)
- Chrysler supported vehicle reports and recorded data from first coverage up to the most recent supported vehicles
- Ford supported vehicle reports including ACM and PCM (powertrain control modules) data elements from beginning of Ford CDR coverage up to the latest ACM which now contain pre-crash data
- Ford PCM data timing relating impact to “time 0” and restraint deployment signal (RDS) reception
- General Motors CDR reports by generation including ROS (rollover sensor) data, Engineering Translation reports including the latest model year ACM data and variants. GM section will include Holden vehicles for Australia and region classes.
- Honda CDR Reports, including examples form real-world crashes.
- Mazda vehicles including sample reports from real-world crashes.
- Mercedes vehicles supported and the data from their ACM
- Nissan CDR Reports - including a fuse panel guide for all supported Nissan vehicles to assist in back-powering (Nissan Owners Manuals do not include this information).
- Suzuki CDR Reports and sources for back-powering information
- Volvo vehicle CDR reports - note: Volvo provides coverage back to 2011 model year
- Toyota ACM data including Generation 1, Generation 2 and the newly added Gen 3 (12EDR) modules, both with and without pre-crash
- Accuracy and Reliability as displayed through results of controlled testing from various sources
- Case studies and in class assignments to tie CDR report analysis to crash investigation
- Hyundai and Kia EDR Tool reports and content, including key information on data integrity will be discussed.
Other course resources included on USB Flash drive with class materials include:
- extensive reference material including sample CDR files in .CDRX PDF format for virtually every CDR System supported ACM/PCM/ROS
- listing of available CDR/EDR Accuracy and Reliability studies and papers
- Class hmaterials in NON-WATERMARKED format!!! - in PDF format so "clean" copies i.e. those without students notes can be printed for reference
- Legacy vehicle coverage distributed via an eLearning module provided in the class DropBox (Includes pre-Modely Year 1999 GM vehicles without pre-crash, 2001 Ford Taurus, and 2001-2004 Ford Crown Victoria
- Other older systems will be moved to eLearning modules within the USB drive foldersx to make room for new material as required
- eLearning modules include Adobe PDF handouts
This class is days 2 through 5 of the complete CDR System Operation, Analysis and Applications Series and is available to attend as part of a 5-day complete series, or as an individual 4-day class for those requiring only training in the Analysis and Application of CDR data. Limited oportunities for those seeking an update MAY attend days 3-5 for reduced enrolment. Inquire for eligible classes!
Completion of the CDR System Operators or equivalent course is a recommended pre-requisite. (The CDR Technician class as offered by Collision Safety Institute since 2008 or one of their Technician Class trainers is an acceptable pre-requisite, as is the IPTM Methodologies class.)
