Crash Data Retrieval (CDR) – Vehicle Accident Reconstruction
The Bosch Crash Data Retrieval System is a litigation proven tool that allows the Professional Analysis and Consulting accident reconstruction experts investigating vehicle crashes the opportunity to image crucial crash data parameters leading up to and during a crash. This crash data, which is stored in the vehicle’s Airbag Control Module (ACM), may be used to make informed decisions about the accident based on the crash data “imaged” from the vehicle in question. The system currently supports most vehicles on the road today.
The ACM’s potential capability to save data after a crash has caused some to mistakenly refer to it as an “Event Data Recorder” or EDR, sometimes referred to as the “Black Box”. In reality, the ACM’s primary job is to detect sudden changes in direction and/or rotation and, when appropriate, deploy restraint devices like airbags. The ACM uses certain bits of information including that from crash sensing systems, seat belt related sensors and occupant detection systems, to decide whether or not and when to deploy airbags and other restraint system devices. When certain conditions are met, the ACM may record data associated with these sudden changes in direction and/or rotation (i.e. a crash) which can later be “imaged” by the CDR tool.
Benefits of Imaging Vehicle Accident Data for vehicle accident reconstruction include:
- Pre-crash vehicle data (up to 5 seconds prior)
- Vehicle speed
- Steering wheel angle
- Crash severity (delta-V)
- Brake switch status
- Seat belt status
- Accelerator pedal position
- Order of impacts, if multiple
- Transmission gear position
- Airbag deployment data
- Occupant presence
- A proven track record of admissibility in litigation
Easily recover vehicle crash data from multiple manufacturers including:
- GM – Cadillac, Buick, Chevrolet, Pontiac, Oldsmobile, GMC, Saturn,
