What data is recorded on the EDR unit?
At this time the data that is recorded varies depending on the vehicle manufacturer, make, model and model year. In general it may record data elements like vehicle speed, engine speed (in RPMs), percent throttle, braking status, longitudinal or forward post crash velocity changes, and seat belt usage. By 2011, all vehicles being sold in the United States that collect EDR data, (most models by 2010) will be mandated under federal law to have EDR units that are available for public retrieval, and that are mandated to record a minimum of 15 data elements specified under the law, including those stated above, in events detected by the airbag module, under a standard event detection threshold.
