EDR SYSYTEM- Event Data Recorder

What is EDR?

EDR (Event Data Recorder) is an onboard device that records data about road incidents—commonly known as a vehicle's "black box". Its function is to automatically record selected driving parameters several seconds before, during, and after a collision or road accident. EDR does not record audio or video; it exclusively focuses on technical data essential for safety analysis.

Who is EDR Intended For?
According to the UNECE R169 regulation, the EDR:

EDR SYSYTEM- Event Data Recorder

is exclusively intended for vehicle manufacturers (OEM)—cannot be installed by private individuals or third-party companies.

EDR SYSYTEM- Event Data Recorder

is mandatory for new vehicle types approved from January 7, 2026, in categories:N2 and N3 – Heavy-duty vehicles (trucks),M2 and M3 – Buses and coaches.

EDR SYSYTEM- Event Data Recorder

is mandatory for all newly registered vehicles from January 7, 2029.

FAQ

What Data Does the EDR Record?

  • Vehicle speed
  • Accelerator pedal position
  • Brake pedal position or braking status
  • Longitudinal (X-axis) and lateral (Y-axis) acceleration
  • ABS system status (active/inactive)
  • Engine RPM
  • Steering wheel angle
  • Driver’s seatbelt status (fastened/unfastened)
  • Brake light activation status
  • Electronic Stability Control (ESC) status

  • Event start time (T0)
  • Activation time of safety systems (e.g., airbags, seatbelt pretensioners)
  • Peak collision acceleration recorded
  • Velocity changes (delta-V)
  • Status of collision mitigation system activation (e.g., AEB, FCW)
  • Secondary collision information (if applicable)

  • Vehicle Identifier (VIN) or another EDR-specific identifier
  • EDR software/data recording version
  • Recorder operation status (whether recording was active)
  • Event timeframe (timestamp in milliseconds before/after T0)
  • Number and type of recorded events (e.g., whether one or multiple impacts were recorded)

NOTE

Regulation R169 does not require recording audio or video. All data must be stored locally, protected against manipulation, and provided exclusively to authorized entities in accordance with data protection regulations (e.g., GDPR in the EU).

Key Benefits of Implementing EDR

By implementing EDRs that comply with UNECE R169, manufacturers can not only meet international standards but also unlock powerful data-driven opportunities. These systems support continuous development of driver-assist technologies, help optimize design, and ensure legal clarity when it matters most.

Although EDR data isn't accessible to end-users, manufacturers in cooperation with fleet operators can analyze it, indirectly enhancing fleet risk management and driver safety optimization.

01

Precise Accident Analysis

Thanks to recorded technical data, investigators, manufacturers, and safety engineers can accurately reconstruct incidents, identify causes, and determine potential human or systemic errors.

Supporting ADAS Development

EDR data is valuable in enhancing Advanced Driver-Assistance Systems (ADAS) and autonomous driving technologies, contributing to overall road safety improvement.

Improved Vehicle Design

Manufacturers can analyze the effectiveness of passive (e.g., airbags) and active (e.g., emergency braking systems) safety measures, directly influencing future vehicle designs.

Legal Support

In certain jurisdictions, EDR data can serve as evidence in civil or criminal proceedings—provided compliance with local legislation and data protection laws.

 

Reduction of Fleet Accident Costs

Although EDR data isn’t accessible to end-users, manufacturers in cooperation with fleet operators can analyze it, indirectly enhancing fleet risk management and driver safety optimization.
