EDR Crash Analysis for Motor-Vehicle Claims and Litigation
EDR Crash Analysis for Claims, Investigations, and Litigation
EDR Crash Analysis is the evaluation and interpretation of recorded vehicle information obtained from a supported Event Data Recorder following a qualifying motor-vehicle crash.
Crenshaw Investigations provides EDR/CDR retrieval, vehicle inspection, photographic documentation, EDR crash analysis, and written reporting for motor-vehicle claims, investigations, and litigation throughout California.
A meaningful analysis identifies the applicable recorded event or events, applies vehicle-specific definitions and limitations, and compares the available values with photographs, damage, statements, police reports, repair records, and other evidence relevant to the assignment.
Have an active motor-vehicle matter, or want a practical overview of EDR evidence?
What Is EDR Crash Analysis?
EDR Crash Analysis involves reviewing EDR/CDR native files and manufacturer-generated reports, identifying the applicable recorded event or events, and evaluating the recorded parameters within the definitions and limitations established for that vehicle.
The analysis may address event status, pre-crash timing, vehicle speed, braking, accelerator or throttle input, steering, restraint status, deployment commands, longitudinal or lateral delta-V, crash-pulse timing, ignition-cycle information, and other supported values.
EDR Crash Analysis also requires attention to manufacturer-specific terminology, sign conventions, recording intervals, event-locking behavior, threshold requirements, module condition, and whether the recorded event reasonably corresponds with the crash under review.
The purpose is to explain what the available recorded information supports—and what it does not establish—within the agreed scope of the assignment.
EDR Crash Analysis Services
Depending on the vehicle, assignment, and requested scope of work, EDR Crash Analysis services may include:
- Review of EDR/CDR native files and manufacturer-generated reports
- Identification and comparison of recorded event records
- Evaluation of speed, braking, accelerator, steering, restraint, and deployment information
- Review of longitudinal and lateral delta-V, crash-pulse timing, and event sequence where recorded
- Comparison of recorded values with photographs, damage, statements, and other evidence
- Identification of vehicle-specific recording limitations and data gaps
- Written EDR crash analysis reporting
- Technical consultation regarding recorded findings and limitations
What Data May Be Reviewed in EDR Crash Analysis?
The information available for EDR Crash Analysis varies by vehicle make, model, model year, installed systems, event type, recording parameters, and module condition. Depending on the supported vehicle and recorded event, available information may include:
- Pre-crash vehicle speed
- Service-brake status and brake-pressure information, where recorded
- Accelerator-pedal or throttle input
- Engine or electric-motor speed
- Steering input
- Stability-control and ABS activity
- Longitudinal and lateral delta-V
- Crash-pulse timing and event sequence
- Driver and passenger restraint status
- Airbag and pretensioner deployment commands
- Event status, event timing, and multiple-event information
- Ignition-cycle, odometer-at-event, and diagnostic information, where recorded
- Other manufacturer-specific vehicle and crash information
How EDR Crash Analysis Assists
EDR Crash Analysis for Attorneys and Law Firms
EDR Crash Analysis may assist attorneys in evaluating disputed speed, braking, accelerator input, steering, restraint use, crash severity, event timing, and the sequence of multiple impacts. Recorded information may be compared with statements, photographs, police reports, damage, repair records, and other evidence.
EDR Crash Analysis for Insurance and Claims Professionals
Claims professionals, SIUs, corporate risk departments, and authorized business clients may use EDR/CDR analysis to evaluate consistency, exposure, crash severity, event sequence, and technical questions that may require further investigation or coordination with counsel.
EDR Crash Analysis for Vehicle Owners
Vehicle owners may use recorded vehicle analysis to better understand what the available EDR data shows concerning vehicle operation, restraints, deployment activity, delta-V, event timing, and other supported parameters surrounding a qualifying crash event.
How EDR Crash Analysis Can Assist a Case
When crash accounts conflict or technical issues are disputed, EDR Crash Analysis can provide objective vehicle information that may be evaluated with the other evidence in the matter.
EDR Crash Analysis Compared With a Driver Account
If a statement describes hard braking, accelerator release, steering input, or a particular speed before impact, the available EDR parameters may provide an objective technical record of the recorded pre-crash interval.
The analysis can compare those values with the driver’s account, photographs, vehicle damage, and other evidence relevant to the disputed issue.
EDR Crash Analysis of Multiple Recorded Events
Some supported vehicles may contain more than one event record, particularly in a multi-impact crash or when another qualifying event occurred before or after the loss under review.
Analysis of event status, timing, pre-crash values, delta-V, restraint information, and other recorded parameters may help identify which record most reasonably corresponds with the crash being investigated.
EDR Crash Analysis and Recording Limitations
An EDR report may show that a particular parameter was not recorded, that the event did not meet a required threshold, or that the available interval does not answer the disputed question.
Identifying those limitations is a necessary part of EDR Crash Analysis and helps prevent the recorded information from being overstated.
