CDR / Crash Data Retrieval

EDR / Event Data Recorder

When investigating a car accident or insurance claim, no single piece of information can paint a complete picture of what occurred and who was at fault. Law enforcement, insurance professionals and investigators know this all too well.

First-hand and eyewitness accounts of the incident are notoriously unreliable. Environmental factors and road debris can change between the occurrence of the event and the on-scene investigation. Video of the incident – if it’s available — may not capture key in-vehicle actions that influenced a crash.

As such, any comprehensive investigation requires a detailed analysis of the various human, vehicular, and environmental factors that may have influenced or caused the event. Within that universe of evidence, an unbiased and reliable source of information has emerged – and even grown more powerful as in-vehicle technology has advanced: The Event Data Recorder (EDR), which is integrated into nearly every car, light truck, and SUV sold in the U.S. since 2013. The EDR is a device that automatically records important technical information inside the vehicle in the seconds before, during, and after an accident or critical event.

Many consumers may be unaware that the EDR exists, as the EDR does not have an interface that displays the data it records inside the vehicle. Furthermore, the EDR only captures and stores data when certain events occur, such as when airbags are deployed or when sensor readings consistent with a collision trigger its recording function. Because there is no on-board interface to display EDR data, an external tool is required to download and present any data recorded by the EDR.

This is where the Bosch Crash Data Retrieval (CDR) Tool comes in. The Bosch CDR Tool is a reliable, versatile, and increasingly powerful industry standard platform that retrieves EDR data from the vast majority of modern vehicles. After EDR data is downloaded from a vehicle and saved in a secure file format, the CDR Tool software generates a detailed report that can be used by investigators in a variety of ways. Over the past two decades, CDR reports have become a vital part of investigations conducted by insurance claims adjusters and Special Investigative Units (SIUs). They are also routinely used by law enforcement agencies. EDR data translated by the Bosch CDR Tool is admissible in court, and CDR reports have been used to identify fraudulent insurance claims, verify insurance claims, and assess vehicle speed and driver input in the moments leading up to a crash.
