When we say “Black box” or data recorder (a device that records data with a specific algorithm), the first thing that comes to mind is airplanes, and of course they are mandatory in all aircraft. However, from the summer of 2024, they will be mandatory in all new cars sold in the EU.

Traffic accidents also have financial consequences for the people involved in them, and it is often difficult to decide who caused the accident. That’s why the EU passed a regulation that all new cars (class M1 – up to eight seats) must have an EDR (Event Data Recorder) built in, like N1 class vehicles, including pickups and vans whose weight does not exceed 3,500 kilograms. This decision applies to all 27 EU members (Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands , Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden).

According to European Commission documentation, EDR records data on the speed, braking, position and tilt of the car on the road, as well as how safety systems react. The device will record these parameters in a short period of time, five seconds before and 0.3 seconds after the impact. Of course, the data must be recorded with high precision and ensure its persistence. In addition, the device analyzes whether the emergency call system has been activated. It is known that the eCall system has become mandatory in the EU since April 2018.

The EDR will be built into the airbag control unit and cannot be turned off. Activates automatically when seat belt pretensioners and airbags deploy. In addition, it starts recording when the vehicle’s active hood pops up or when there is a lateral or longitudinal speed change of more than 8 km/h within 0.15 seconds.

All data stored by the EDR belong to the owner of the vehicle and will only be available to the competent authorities to assist in the reconstruction of the accident. The device works on the principle of a closed loop, and the data is collected anonymously to prevent manipulation if it falls into the wrong hands. The last four digits of the vehicle’s VIN number are not stored, nor are any other types of data that would reveal the identity of the owner.
