What is EDR “black box” crash data?

Vehicle Event Data refers to the information recorded by a vehicle's onboard systems. This data includes a wide array of parameters related to the vehicle's operation and performance. Some key aspects of this data include: 

Pre-Crash Data (5.0 Seconds Prior to Impact): This includes vehicle speed, brake and accelerator pedal use, steering input, and more, providing a snapshot of vehicle dynamics before a collision.

Crash Type, Recency, and Severity: Information such as the direction of impact, g-forces experienced, and other details that denote the nature and severity of the crash.

Occupant Information: Number of occupants, seatbelt usage, and related data are recorded to understand the conditions within the vehicle during an incident.

 EDR-supported vehicles can record a wide array of data, which includes:

Crash Event List: Up to six crash events with details on the event order, severity (Delta-V), crash pulse time, and type of impact (e.g., front, rear, side), along with recency details.

Pre-Crash Data Sets: This encompasses 55 to 75 data points per record, including raw data like vehicle travel speed, brake and accelerator pedal usage, steering angle, engine speed, anti-lock brake activation, gear position, seatbelt use, airbag deployment, and occupancy status.

Collision Sciences offers enhanced information such as:

Organised Crash Event Records: These records include contextual data like crash event order in a table format, added severity context, calculated forces, and impact direction.

Calculated Pre-Crash Data Points: Includes vehicle deceleration, braking force level, steering direction, and distance to impact.

Statistical Injury Risk Analysis: Links Delta-V to EDR studies on injury risk, providing a biomechanical and epidemiological perspective.

Potential Fraud and Liability Flags: Analysis of pre-crash data to identify discrepancies in reported circumstances, driver behavior, and avoidance opportunities.

Vehicle Health Diagnostics: Includes engine and transmission diagnostics, emissions test failure flags, and enhanced vehicle diagnostics.

Freeze Frame Data and Diagnostic Safety Codes: Provides specific information related to Diagnostic Trouble Codes (DTCs) and safety-related diagnostics.

DTC-based Repair and Cost Information: Insightful data for vehicle maintenance and repair estimations.

Recall Information & IIHS Safety Flags: Essential for understanding the safety record and recall history of the vehicle.

Vehicle Market Value and Specifications: Information on the vehicle's current market value and specific details like weight.

VIN History: A comprehensive record including historical data such as Registrations/Compliance, write-off and theft records.
