Most commercial vehicles in use today have some form of event data recorder (EDR).  These EDRs monitor and record data on the databus of the vehicle, and often are capable of providing information about the kinematics of a vehicle before, during and after a major collision.

Understanding how to access, recover, and interpret these data is important to engineers and police involved in collision reconstruction, as well as fleet managers, attorneys, insurance companies and researchers seeking to prevent future accidents.

Course Highlights/Features:

  • Case Studies
  • Basic Validity Testing in a Hands-on Environment by performing EDR downloads in the 'field'
  • Actual Engine Modules will be available for downloading
  • Hands-on, Interactive Instruction
  • Field Day
  • Focuses only on Heavy Truck (Commercial Vehicle) EDRs
  • Testing and Evaluation
  • Class size is limited ...Sign Up Today!

Audience:

This short course is designed for:

  • Police and Civil Accident Investigators
  • Engineers with Forensic Practice
  • Researchers Interested in the Application of Truck Event Data to Highway Safety
Objectives:
By attending this course, you will walk away...

Knowing how to:
  • Access the data and preserve it so that it is viable evidence in court or civil proceedings
  • Troubleshoot connection problems between the PC and the engine computer after severe crashes
  • Access the event data stored in late model heavy trucks, including Detroit Diesel, Caterpillar, and Cummins engines
  • Become familiar with the published research into accuracy, reliability, and application of the data
And Understanding:
  • How the reported data are measured and calculated, so that valid interpretations can be made
  • The known limitations of EDR data, including when data is not captured
  • How data are collected and how they can be validated
