Event Data Recorder — EDR

Advanced Research Test EDREvent Data Recorders or EDR devices, installed in the vehicle, record what happens in your car during an airbag deployment or wake-up speed change situation.  Typically these devices record pre impact speed, Delta-V or speed change in the event, and possibly other inputs like seat belt operation, and throttle position.  Each manufacturer has their own set of criteria and values.

Photos shown are for research and testing of an advanced EDR.

EDR systems can be much more robust and offer many other features which would be very valuable to fleets and businesses.  Photos shown here detail testing of an advanced EDR device.  Selected acceleration, deceleration, turn, and other tests are performed with the NEV before testing with real vehicles.

EDR systems provide real credibility associated with impacts because they provide an unbiased record of what happens.  This information can be vital to document what happened in the “event”.

EDR’s are typically referred to as Black Boxes.  However, in looking at the attached photos none of the devices are actually black.  The advanced EDR is in a white box and an actual Flight Data Recorder is orange.

EDR’s are in the news and in your car.  Every vehicle today has airbag devices.  Every OEM has their own data that they can retrieve post impact so they can evaluate how well their car and safety devices performed in the crash.  Other data from the EDR requires special diagnostic and test equipment for data retrieval.

The National Highway Traffic Safety Administration, NHTSA, and the National Transportation Safety Board, NTSB, have been very active with EDR issues.  NTSB has a long history with the five transportation mediums that embrace EDR: highway, rail, pipeline, aircraft and vessels (boats/ships).
