Crash Data Retrieval (Automotive Black Box)

The Crash Data Retrieval System by Bosch allows us to download vital data from the accident vehicle air bag module (computer) including vehicle and engine speeds, throttle position, and brake and seat belt status prior to, during, and following impact.

Data from the Crash Data Retrieval System, or CDR, aids in the reconstruction of many vehicle accidents.  It also helps identify where any vehicle malfunction occurred.  The CDR output diagram below was downloaded from a vehicle with a stuck accelerator which resulted in a fatal accident.  Air bag modules record selected data for both an airbag deployed accident and a non-airbag deployed accident that is severe. Examples of reports are below:

Example Deployment CDR Report
