Accessing and Interpreting Heavy Vehicle Event Data Recorders
I.D. # C1022 Duration 3.5 Days

Recent advances in commercial vehicle equipment have increased the potential for incident-related data to be recorded surrounding a collision event. What some have called a "black box" is more properly referred to as a Heavy Vehicle Event Data Recorder (HVEDR) as defined by the SAE J2728 HVEDR Recommended Practice. The term HVEDR is used to describe any type of electronic function that has the capability of storing data surrounding a defined event within an electronic control module found on a heavy truck or bus and that communicates on the SAE J1939 or J1587/J1708 data communications protocol. This course highlights the various vehicle systems and triggering events that may provide data useful in a collision investigation. Guided by recognized industry experts, techniques for preservation and interpretation of HVEDR data will be explored. This highly interactive workshop includes in-class instruction, demonstrations and practical hands-on experiences for acquiring and analyzing data from commercial vehicles.

This course will include discussions on the four standards. Anyone who wishes to do so can purchase these ahead of time by contacting SAE Customer Service. Please note: purchasing the SAE Standards is not required.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 24 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103.

Please note, attendees are required to bring their laptops to this seminar to utilize the electronic handout materials and participate in hands-on data extraction and analysis exercises.  
Note: Last day of class ends at approximately 12:30 pm


Learning Objectives
Upon completion of this workshop, you will be able to:
  • Identify the potential sources of HVEDR data available on commercial vehicles
  • Utilize various methodologies for accessing and imaging data from HVEDRs while preserving the data in its original electronic format within the control module
  • Compile documentation of the vehicle and the imaged HVEDR data to properly establish foundational facts that tie the data to the vehicle and to ensure the reliability of incident specific data
  • Properly interpret data from HVEDRs and understand the limitations of this data
  • Analyze HVEDR data in the context of collision reconstruction

Who Should Attend
This course is a must for anyone involved in the investigation and analysis of commercial vehicle crashes who needs to understand the types of event data that are available on commercial vehicles, how it is generated, how it is accessed from the vehicle, and how to apply it in a collision reconstruction. In addition, this course can be valuable to the motor carrier safety manager, independent adjusters, claims managers or attorneys handling commercial vehicle collisions.
Prerequisites

An undergraduate engineering degree or a strong technical background is highly recommended. A basic knowledge of college physics and calculus, as well as a familiarity with commercial motor vehicles is expected.


***Please be advised that this course involves one or more of the following: driving and/or riding in a vehicle; participating in a vehicle demonstration; and/or taking part in an offsite tour using outside transportation. You will be required to sign a waiver on-site and produce a valid driver¿s license from your state/country of residence.***
