Crash Data Retrieval System
  • Vetronix Corporation

History - Vetronix and GM
  • ? Vetronix/GM Relationship Began in 1984.
  • ? GM Selected Vetronix to Develop First Event
    Data Retrieval Unit (EDRU) in 1990 (For GM use
    only).
  • ? In 1999, GM Awarded Vetronix with
    Exclusive Contract to Develop
  • Crash Data Retrieval System (CDR) for GM
    and the aftermarket.

3
History - Vetronix and Ford
  • ? In November, 2000, Ford agreed to let Vetronix
    develop software that will interface with the
    Crash Data Retrieval system (CDR) and enable
    users to download crash data from select Ford
    vehicles.
  • ? First Ford Upgrade (software and cables) will
    be available in Fall, 2001.

NTSB Recommendation -
  • The National Transportation Safety Board (NTSB)
    has formally proposed that automobile
    manufacturers equip their products with recorders
    capable of storing crash data that could help
    develop a safer national transportation system.
    The Vetronix CDR System helps further the NTSBs
    recommendation by creating a product that
    downloads the data stored in recordable airbag
    modules.

5
Vetronix CDR System
  • Downloads pre- and post-crash data from the
    vehicles airbag module to a laptop computer.
  • The Windows? based software CDR software presents
    this data in an easy-to-read graphical and
    tabular format.
